How To Jailbreak iPhone OS 3.1.3 using Redsn0w for iPhone 2G/3G

February 8, 2010 — by Simon Ng190

As reported earlier, iPhone Dev team has released redsn0w 0.9.4 for jailbreaking iPhone 2G/3G running iPhone OS 3.1.3. If you are planning to upgrade your iPhone to OS 3.1.3, this guide walks you through the whole jailbreak process.

Before we begin, please read through the note carefully:

  • This guide is intended for jailbreaking iPhone 2G and 3G (no unlock needed) running iPhone OS 3.1.3.
  • For iPhone 3G users that requires blacksn0w or ultrasn0w to unlock your iPhone, please stay away from iPhone OS 3.1.3. DO NOT upgrade your iPhone to OS 3.1.3 as it also upgrades the baseband version that is unlockable.
  • For those using iPhone 3GS, please stick with iPhone OS 3.1.2. DO NOT upgrade to 3.1.3 as all popular jailbreak tool (e.g. blackra1n) do not support jailbreaking your device on iPhone OS 3.1.3.
  • Make sure you use iTunes 9.0 or up for the jailbreak. If you are using older version of iTunes, please upgrade it first. You can download the latest version of iTunes from Apple.
  • As usual, before jailbreaking, make sure you have backup all your contacts, sms, photos, etc via iTunes. Simply sync your iPhone and backup the iPhone data.
  • Disclaimer: Jailbreaking may void your warranty of iPhone. Again, jailbreak it at your own risk. There is no guarantee that this guide works on all iPhone devices.

Okay, let’s go straight to the jailbreak procedures.

Upgrading to iPhone OS 3.1.3

WARNING: Let me highlight again. This guide is for iPhone 2G and 3G (using official sim card) only. If you want to have your iPhone 3G unlock, please stay away from upgrading to iPhone 3.1.3.

1. Download iPhone OS 3.1.3 firmware (2G / 3G) and save it into a folder.

Note: Some browsers mis-recognize the .ipsw file as a zip file. You may need to end up with a file with extension (.ipsw.zip) after download. You can simply rename the extension from “.ipsw.zip” to “.ipsw”. In case your browser automatically extracts the .ipsw file, I suggest you to use Firefox to download the firmware file.

2. Connect your iPhone via USB and launch iTunes.

Note: I suggest not to use the docking for the jailbreak. Connect the USB cable directly with your iPhone.

3. Restore your iPhone with iPhone OS 3.1.3. For Windows, hold SHIFT key and click on the “Restore” button and select the firmware file (i.e. For 3G, please select iPhone1,2_3.1.3_7E18_Restore.ipsw. For 2G, please select iPhone1,1_3.1.3_7E18_Restore.ipsw) you have just downloaded. For Mac, hold option key and click on the “Restore” button and select the firmware file to restore.

4. If you’re not using official sim, your iPhone will not be recognized by iTunes after restoration. Don’t worry. It’s normal. You can then close iTunes and continues with the next step.

Jailbreaking Your iPhone using Redsn0w

5. Next, we will jailbreak your iPhone using redsn0w. You can download redsn0w 0.9.4 here (Windows / Mac). Once download it, extract it.

6. Also, you’ll need the iPhone 3.1.2 firmware during the jailbreak process. Download it here (2G / 3G).

7. Once you got everything prepared, you can start to launch “redsn0w” to start the jailbreak process.

Redsn0w Logo

8. Click “browse” and select the iPhone 3.1.2 firmware file. For iPhone 2G, please select iPhone1,1_3.1.2_7D11_Restore.ipsw. For iPhone 3G, please select iPhone1,2_3.1.2_7D11_Restore.ipsw. Redsn0w then verifies your firmware file.

redsn0w ipsw identified

9. If your firmware is correct, click “Next” to continue. Select “Install Cydia” and “Unlock”. Then click “Next” to continue.

Note: For iPhone 3G user, you will not see the unlock option.

Note: If you have pwned your device before, I still suggest you to uncheck the “Already pwned” option. From my experience, if I select this option, I can’t go through the whole jailbreak process.

redsn0w select option

10. (Optional and for iPhone 2G only) Next, you’ll be prompted to provide the bootloader files. You can download the bootloader (3.9 / 4.6) here. Once download, please click browse and select the bootloader files. Then click “Next” to continue.

redsn0w select bootloader

11. Now, make sure your iPhone is turned OFF and connected with your computer via USB cable. If you haven’t done so, simply connect it with USB and then power it off before you click the “Next” button.

redsn0w plug in iphone

12. Once you click “Next”, follow the procedures to put your iPhone into DFU mode. If you fail to do so, don’t worry. It won’t brick your iPhone and you can simply go through the procedures again until you get it work.

redsn0w put into DFU

13. If you have successfully put your iPhone into DFU mode, redsn0w will do the rest. Just sit back and relax.

redsn0w jailbreaking

14. While jailbreaking, your iPhone will show downloading jailbreak data, flashing NOR, etc. And, just don’t touch your iPhone and keep waiting.

Quickpwn - Jailbreak #1

15. Once completed, redsn0w will let you know the jailbreak process is successful. Your iPhone will be restarted and automatically launch BootNeuter (for 2G only) to perform unlock. This process will take 3-5 minutes to complete. Be patient. When complete, your iPhone will be rebooted.

redsn0w jailbreaking done

16. After reboot, your iPhone should be jailbroken. Lastly, sync back your backup data with iTunes and restore all your contacts & SMS.

  • Thanks! But I got a question here.

    That means for 2G it can be unlocked? Is it true?


    • @Dennis,

      Yes, you’re right.

      • Richard

        Hi Simon

        my iPhone 3G ver. 3.1.3 Baseband 05.12.01. well everything was done, but my iPhone seems to be stuck in “Downloading Jailbreak Data…”
        What should be done now??
        Pls reply….


        • Kapil

          @Richard – Were you able to solve this? Even my iPhone is stuck on this step.

          @Simon – Could you please help. all the steps till it shows “Downloading Jailbreak data…” were done properly.


      • deepanshu

        even after doing this whole process ..
        after showing downloading jailbreak data screen it gets back to the invalid sim situation..
        again that emergency call ..
        now what should i do.?

    • George Swanson

      Yes Dennis the 2G can be unlocked, if you need a windows version, use kittyra1n


  • AJ

    Simon – I have used geohotz blackra1n to unlock my iPhone 3G to 3.1.2 with baseband 5.11.07?

    Can go for this guide to upgrade to 3.1.3?
    Are the warnings to hold off upgrade for iPhone 3GS (5.11.07) only?


    • @AJ, please hold off the upgrade as you are using blacksn0w to unlock.

  • Lisa

    Simon, I’m a little bit confused by the instructions. (I have an iPhone 2g, btw).

    First, we’re to upgrade to firmware 3.1.3 following Steps 1-4.

    In Step 6 you say one needs firmware 3.1.2 and you give a download link. I’ve already got firmware 3.1.2 from the previous jailbreak (using B1ackrain). Do I skip Step 6? Why would I need firmware 3.1.2 after having just upgraded to firmware 3.1.3?

    Also, my phone uses a vodafone UK card – unlocked and jailbroken three times now. No problems. Are you saying if we jailbrake now to upgrade to firmware 3.1.3 – this will prevent me from using the sim card?

    Sorry for the questions, but it’s just not clear to me. And I do not want to mess up my phone. I’m happy to jailbreak again – but I need to know the answers first:).

    Thanks for such a helpful blog!

    hi, i got a question too: my Iphone (3.1.2) with O2 simcard from uUK was unlocked with blakrain/cydia before, now i live in Canada and i used a Telus simcard,unfortunately (i dont know WHAT kind of blackout i’ve got the same minute) but i agreed on the upgrade from Itunes to 3.1.3..ofcourse i lost my blackrain and etc. was trying to install it again and in the process when it came to the point to the itunes question of “restore”, i did that as well.. the result is- my iphone locked itself completely, i cannot use it all. it gives me only the option of “emergency calls”. i went to few place to unlock it, but they all say it is impossible, and might be lost forever or in a good case scenario i will to wait atleast 3 months..any ideas/advices?
    thanks in advance

    • martyn garbutt

      hi i have same problem. fitted a new comms board from america and itunes wont recognise it. emergancy calls only.did you find a cure?

    When I upgraded to 3.1.3 I thought I would never get my jailbreak apps back. BUT this worked! I still have all my information (contacts, apps, etc) and now I have my cydia right back where it belongs! What a life saver! I just can’t live without BiteSMS! Thanks Simon!

    You are an excellent man.

    Cool .. it’s useful for a JB loser such like me .. haha .

    Anyway , many thanks for your sharing.

  • Chris

    Hi Simon I had follow all ur instruction but it end up showing the Apple logo on my iPhone 2G but I been waited for about 2 hours. Does it need to take so long?

    Help me

    • @Chris, it won’t take too long. Looks like there are some issues during the process. I suggest you to go over the procedures again. Usually, a second attempt will work.

  • raddg

    Thanks… it worked for my 2G which I had to update to 3.1.3. In comparison to blackrain and the added steps to remove a few glitches, redsn0w got it unlocked no need to do that diskaid trick, ready to go with your new sim. Did it a couple times, changed the bootimage for fun, getting into DFU is second nature.

  • pankaj

    I tried running redsnow-win_0.9.4 but my iphone never reboots even after waiting for long..if I reboot it manually, i do not see cyadia.. my phone is 3g 3.1.3 with firmware 5.12.01

  • tippler

    Ok I have a 3G still using version 3.0 firware 04.26.08 and am so confused by these instructions?…. can I use the above method and upgrade or will this not work on my phone? BTW I am on Tmobile.

    • @tippler,

      I think you are using an unlocked iPhone 3G. This guide is not for you as upgrading iPhone to 3.1.3 may make your iPhone unlockable. That means you’ll not be able to use it on t-mobile. If you really need to upgrade your iPhone, I suggest you to upgrade it to OS 3.1.2 and jailbreak it using blackra1n. You can further check out this guide.

  • Fred

    2 Quick questions: I had the battery of my jailbroken iPhone 2G 8GB replaced last week at the Apple Store but they swapped my whole phone and gave me a new iPhone 2G that is “ready to register” (showing the USB-to-Itunes graphics), and I am only able to make emergency calls.
    (1) Can I go ahead and follow your steps here?;
    (2) How do I know which OS version Apple installed in my new 2G phone? I called the Apple Store and they told me they did not know.
    Thanks a lot for taking the time to write this manual and answer questions!

    • @Fred,

      As you’re using iPhone 2G, you can apply the above procedures to jailbreak and unlock your iPhone. Let me know if you got any problem.

      • Fred

        Hi Simon,
        Thank you so much for answering! I am trying to follow your RedSnow steps, but the problem is that in Steps 2-3, when I USB my iPhone to my Mac I get the “Welcome to your New IPhone” screen that prompts me to “get started” by “1. Activate your iPhone with AT&T; 2. Register and get an iTunes Store Account; 3. Put your contacts, music on your iPhone”… and a “continue” button. That is, I never get to see what you describe in your Step 3: “For Mac, hold option key and click on the “Restore” button and select the firmware file to restore” (I never see a restore button). I took the AT&T SIM out and was able to restore using the iTunes restore backup for my Iphone (so I now see the iPhone icon in Itunes, but I didn’t have to choose any firmware file as suggested in your steps 1 & 3). However, when I put the SIM back on again and USB the iPhone to my Mac, I get the “get started” screen again. Should I ignore it & run Redsnow? Continue with the registration process? I am a bit lost. Thanks again! / Fred

  • Fred

    Ignore my previous post and sorry for the bother. I just went ahead and used RedSnow despite the welcome screen… and it worked beautifully! I just made a couple of incoming/outgoing calls from my just-jailbroken iPhone 2G. It sounds great! Thanks so much for your great posts and help! / Fred

  • didado

    Hey Simon!!

    I followed all the process. I got cydia back on my iphone 3G, but when I try to install any application from itunes, it comes the message: “The application xxx was not installed on the iPhone “my iPhone” because an unknown error occurred (0xE8008001).

    What do you think is the problem?

  • imboone

    Hi, I
    have a question about Jailbreak. I was reading the instructions and I”am confused (don”t know much about computers and how they work). My question to you is will Jailbreak work on ipods?

    Thanks, imboone

    • @imboone,

      Yes, jailbreaking also works on iPod touch. The procedures for jailbreaking iPod touch is very similar as described in this article.

    Hi Simon,
    I successfully upgraded my iphone 2G from 3.1.0 to 3.1.3 using the above guide. Now the problem is I’m not able to restore my earlier backup data via itunes.
    It does show up “Restore in Progress” on the iphone screen and after about 10 minutes progress bar on itunes turns out to show an error message that ‘the iphone was disconnected’.
    In order to restore all contacts and messages, do I need to sync back iphone only or do I need to restore earlier backup?
    Please help me.
    Thanks v much..

    hi my name is raj and i have an Iphone 3gs and it is locked i can do only emergency call and it does not accept any sim card. what should i do. I tried to check my iphone it ia a 3.1.3 version. any one can help me to sort out plzzzz.


  • I got iphone 3GS 3.1.3 32 GB ….from French …. can’t use with Thai sim…… plaaese help me how i can unlock this iphone…?

    • @Yutthana,

      Sorry. For iPhone 3GS running 3.1.3, there is no unlock solution available yet. iPhone Dev team is working on the solution but there is no release timeline. I’ll keep you posted on the release.

  • aks

    My unlock didn’t work..
    I got an iphone shipped from US
    It was supposed to an unlocked iphone 3g and was used by friend there.
    unfortunately before shipping he changed the setting to “restore factory setting” and the phone upgraded itself to 3.1.3 & along with factory settings.
    when i tried to use my local sim here in India..the phone showed the sim as invalid sim.
    Now i tried to jailbreak using your above instruction. I saw the warning that its only to be done will offical sim.. but a few lines below – step no.4 it was said its ok even if its an unoffical sim.. this caught me in dilemma but i still proceeded.
    I got stuck after step no 13. the redsnow was saying “please wait till phone reboots” .. which didn’t happen even after 20 mins, I lost patience and tried switching it on manually & found out it had gone to emergency call mode.
    Now even itunes was saying the phone is with invalid sim.
    earlier at least i was able to use the phone as ipod, now even that is not possible.

    please tell me what to do, it would be of great help if you can give me a solution. FYI my baseband had also changed to 05.12.01 along with the upgrade.

    • @aks,

      As it’s upgraded to firmware 3.1.3, you lose the unlock for your iPhone. As of now, there is no unlock solution for baseband 05.12.01.

    • @aks,

      If your iPhone 3G is with old bootrom, you can try to downgrade the baseband. Check out this post for details.

  • Roobiie

    Thank you very much Simon. i’ve been searching for the net on how I can jailbreak my Iphone 3G 3.1.3 for 2 mos. now. and when I browsed your site, Finally i downloaded this redsn0w 0.9.4. Now I can happily use again my iphone.

    Btw, it was also here when I first learned to jailbreak iphone 2.x

  • aks

    hi simon,
    Read ur blog on using fuzzyband, My issue is .. to install fuzzyband, the phone should be jailbroken, were as my phone is still in emergency call mode, the phone & itunes both are saying sim is invalid

  • Jorge MIguel


    I had an iphone 2g Edge original Running OS 3.1.3 and i followed all the mentioned steps and phases, at first i got it wrong with snowbreeze and now i used Redsnow and got my iphone unlocked and up in top shape

    Thanks man

  • iNeedHelp

    My iPhone is factory-unlocked 3GS 32GB, model MC133; baseband 05.11.07; bootloader 6.4. Bought from Indian Grey market last month with 3.1.2 (7D11) installed.

    I have jailbroken my 3.1.2 firmware using blackra1n RC3. Result: tethered reboot; cydia crashes now and then. Can’t browse the root folder from any 3rd party software i.e., DiskAid/iPhoneExplorer/iFunBox. It says, my phone is jailed.

    Following this post, can I rejailbreak using redsn0w 0.9.4 and upgrade to 3.1.3 firmware keeping factory-unlocked? I use Windows XP, iTunes 9.0.3.

    • @iNeedHelp,

      For iPhone 3GS, I suggest you stay with iPhone OS 3.1.2 and avoid upgrade to 3.1.3. If you really need to jailbreak your iPhone again, I suggest you to follow this post and use blackra1n for the jailbreak.

  • Eduard

    hey i got a question, before this i wasn;t even able to turn it on and i was only able to make emergency calls,
    after doing this im able to turn it on but, i get a msg that says sim locked and i have 2 options “OK” and “UNLOCK” and if press unlock it asks for a pin code
    wasn;t it unlocked? or is there anything else i need to do ?

    • @Eduard, that’s the PIN code you have assigned to lock your phone. Just enter your PIN to unlock the screen.

      Hope u’ll reply.


      • @Richard,

        Presently, there is no solution for unlocking iPhone 3G with baseband 05.12.01. In case you have upgraded your iPhone to 3.1.3, you may try out this solution to downgrade the baseband (only work for bootloader 05.08).

        • Richard


          Thanks for your reply. Well I did everything and got my phone jail-broken, but unfortunately the bootloader is 06.04.
          So is there any solution to unlock iPhone with bootloader 06.04, yet??

          Pls inform, whenever the solution comes out.

  • Bomor

    Sorry if I am in the wrong site. But can you please help

    I have a first generation iPhone 2G, I asked to have it jailbroken and they put version 3.1.3 on it, I have been told not to sync it with iTunes, as it will lock up. If the battery runs out, I have been told again that I will have to jailbreak it again, I am told that all this has to do with version 3.1.3. So evrey time the battry is low, I have to switch it off and charge the battery again.
    Can you please tell me if there is a way to overcome this issue, and how please

    • james

      someone is having you on mate. i have a jailbroken 2g running 3.1.3 firmwere and the battery is always dying cuz my misses is always playing on it lol. and i regulary back it up via itunes. you have nuffing to worry bout 🙂

  • Bomor

    James I appricate you taken the time to email me back, regarding this subject. As I am not at all Technicial when it comes to any type of mobile phone.
    Can you also tell me how easy it is to jailbreak an iPhone 2G or 3G, and where I can get this information from.

    • James

      NO probs mate 😀 well I personally have only jailbroken iPhone 2g the above jailbrake method was really easy and it jailbroke on the first attempt 😀 and since that I had done my mates 2g with the same method, the redsnow makes it really easy with 3.1.3 firmware. Plus is unlock’s it at the same time. Just make sure you back all your stuff up b4 you do it, that way if anything goes wrong you can restore it to the way it was! You will have to back everything up then do a fresh install of 3.1.3 firmware on your iPhone b4 it will jailbrake. This has to b done or it willnot work! When you have compleated the obove steps you just do a restore of the backup you done at the beginning then it will put all your SMS, contacts, Picts, apps ect. If you need any help just let me know,, James..

      • Bomor

        Hey James.
        I cannot seem to backup my Iphone 2G, as it just hangs, I was trying to try my luck at what you suggested, but its just hanging, Remember I first stated that I was told I could not use itunes, with this 3.1.3 firmware. let me Rephrase that, I was told not to try and use this iPhone 2G with itunes with 3.1.3 firmware, as it would hang??
        any suggestions on how to get my iPhone going again.
        Many thanks for your help

  • Meltz

    How do I know if it’s Jailbroken? All my apps are still there and everything looks the same. I went through the whole process, but I think it didn’t work.

    • James

      Hi there meltz. It sounds like it didn’t work. What iPhone and firmware are you useing? I will guide you through the process. 🙂

    • @Meltz, did you see Cydia icon on your home screen?

  • James

    Hi there bomor it seems like you have a problem with the version of iTunes! May I ask what version you are using? And this might seem like a silly question but when you try a backup, are you doing this with a active Internet connection? James…

    • Bomor

      Hey James, I relly do not know how to thank you guys, form all your help. If it were not for people like yourselves, people such as myself would be completely stumped, so thanks.
      I am using itunes ver, and yes I am using a active Internet connection, whening trying to back up, as this is the main computer for my home. This runs two more computers off it

      • Bomor

        James I forgot to add, I am using Windows XP, if that helps, my other computers run on Vista ultimate, maybe there is a conflict? or does it not matter?

    • sachin

      Hey Raj,

      Great to know that u have upgarded ur Ihpone. I would need some help from u,
      I have downloaded all the stuff mentioned in the steps above. Now, when I’m connecting thru Itunes and trying to restore my Ihpone its going thru d normal upgrade process and not asking for the restore path where i’ve stored the iPhone1,1_3.1.3_7E18_Restore. I did not hve the same issue when i upgraded to 3.1.2

      I would really appreciate your support.

      Looking forward to hear back from u.
      Thanking u in advance.


  • james

    hi there bomor, sorry its taken a couple of days to get back. i was on holiday and my battery died on my phone. im not quite sure why it aint backing up. what error message are you getting from itunes? have you tried using one of your other systems? maybe a problem with your itunes! but re-installing itunes can be tricky because it leaves bits of the program all over your system and you have to make sure its all removed before you re-install. so give it a go on one of your other systems and let me know how you get on.. 🙂

  • Sachin

    Hi Simon,

    I have downloaded all the stuff mentioned in the steps above. Now when I’m connecting thru Itunes and trying to restore my Ihpone its going thru d normal upgrade and connection to apple and not asking for the restore path where i’ve stored the iPhone1,1_3.1.3_7E18_Restore.

    I would really appreciate your support.

    looking forward to hear back from u.
    Thanking u in advance.


  • james

    hey sachin. are you holding the shift key then left click the restore??

    • Sachin

      Hi James,

      Really appreciate your prompt response.

      Yes, I’m holding the SHIFT key and then clicking the RESTORE button….
      I’m following the steps as mentioned and not doing any other than that….


    • Sachin

      Hi James,

      Really appreciate your prompt response.

      Yes, I’m holding the SHIFT key and then clicking the RESTORE button….
      I’m following the steps as mentioned…


  • james

    have you turned off auto check for updates on your itunes?

    • Sachin

      Hi James,

      The Auto check updates is also OFF. Ideally, when you hold the SHIFT key and then click the RESTORE button, it brings up the explorer window to choose the restore file. But in my case it always connecting to the Apple server.

      I would really appreciate your support….

    • sachin s

      Hi James,

      I’m still unable to upgrade my 2G Iphone to 3.1.3. I would really be grateful if u can assist me in upgrading the same.

      Still I’m encountering the same issue, The Iphone is connecting to the Apple server for the regular update and not opening the explorer window so as to provide the restore file provided above.

      I request you and would be really be happy 2 hear back from you.

      THanks & Rgds,

  • james

    hi sachin. i feel a little confused about your situation. are you sure you have downloaded the 3.1.3 firmware? it seems like your itunes is not locating the firmware! you have to download the firmware and point itunes to the location of which you saved it to..

    • Sachin

      Hi James,

      I really appreciate the support.
      I have re-downloaded the firmware (iPhone1,1_3.1.3_7E18_Restore) from the link provided above. However, still its going for the normal upgrade. I’m using Itunes ver.

      I’m connecting my IPhone thru the cable, opening Itunes, using the SHIFT key, clicking on the RESTORE button.

      I’m too confused as I didnot encounter the same issue when i upgrade to 3.1.2 and with d same way it opened the xplorer window as askd me for the restore file.

      Please assist.

      Thanks & Rgds,

      • Sachin

        Hi James,

        Apologies if i’m bothering you.

        Request you to please assist me in upgrading my 2G IPhone to 3.1.3.

        Its really difficult for me to understand why its going for a normal upgrade through the apple server and not asking for the restore file.

        I would be really grateful.


      • Josh

        Hey James,
        Sometimes Itunes doesnt recognize the firmware files if they are downloaded as a ZIP. If you rename the firmware file endin in (.ispw ) it should work out better for you.
        I appreciate you sharing your knowledge wit everyone Sachin.
        It helps out alot. I have an old school 2g I kinda messed up and upgraded to 3.1.3 on Itunes. I’ve spent the last two days of my free time doing ALOT of research to try to find the right mods to do to it. I guess patience will pay off in the long run. I did the Redsnow 0.9.4 , and the 3.1.2 firmware but its still one 3.1.3. I did get Cydia down but its showing an Error message: refreshing data…could not fetch. I’m not sure what I should do now because I’ve already been throght the “jailbreak” thing. Any Ideas ?

  • jenny

    Hi Simon/James,

    I have an itouch 2G,n when i run redsn0w 9.4, i dun see the “unlock” option that will lead me to the bootloader files section. Also, if i try to follow the steps ahead without the unlock option, i’ll be stuck at the witing for reboot page when the 30 sec for pressing the home button is up. i’ve tried to jailbreak it a few times and would appreciate some help. Greatly appreciated. Thanks.


    • james

      sorry jenny. i don’t think this break is 4 pods. that’s what you are refereeing to?

    Hello Simon,
    Unfortunately,I upgraded my iphone 3g to 3.1.3 firmware (base band 05.12.01) but someone help me to removed apple and usb logo and my Cyndia was found working perfectly but my problem now is that the phone can’t recognize my sim.
    please help

    • james

      when you update to 3.1.3 it also updates your baseband to (05.12.01) and this is why you have lost your unlock! atm there is no unlock available for this baseband. but it will be available soon as geohot and the dev team are soon to release (fingers crossed) will post it on here as soon as they release to keep you up to date usman..

    • james

      have you tried “fuzzyband” to check if you can downgrade your baseband?? if you have bootloader 05.08 then you can downgrade your baseband and then unlock your 3g agen….

  • Usman

    Thanks James, I have already tried ”fuzzyband” but my baseband not supported. As you said I will keep waiting for dev team.

  • james

    any time usman. im in the same boat as you lol.

  • isneno

      Hi James

      My iPhone is 3G baseband 05.12.01 and boot loader is 06.04. Is it possible to unlock by “ultrasn0w 0.93”??
      I was able to jailbreak my iPhone, but lastly while downgrading base band it showed, “it is not possible as the bootloader is 06.04”.
      So will it work for boot loader 06.04??
      Please confirm me.


      • james

        yes it will work fine. and you can now also update to ios4 as this is also unlockable and able to be jailbroken on the 3g 🙂 if you need the links to get the tools let me know.

              Hi James

              Thanks again. I got it unlocked. I jailbroke my iPhone much earlier, but waited for the unlock software. Well awesome work from Dev Team.

              Thanks to u and Dev Team. It worked perfectly.


  • HAmza


    please help me out…i repeated the process thrice…..just stuck into screen on red snow

    “Please wait while your device is being processed”

    Waitingf or reboot…

    it has been a hr? usually how long is the process?

    • Richard

      Hi Hamza

      I faced the same situation, what you are facing now. Actually the total process takes not more than 15 minutes. So as you described the screen stucks in “Please wait while your device is being processed” or “Waiting for reboot…”.

      I had the same problem, so I installed resn0w 0.9.4 to a new computer, here I used my friend’s computer, then using firmware iPhone1,2_3.1.2_7D11_Restore.ipsw, I easily jailbroke my iPhone 3G Baseband 05.12.01 with Bootloader 06.04. But at that time no unlock tools were available for this version. I could only jailbreak and I have to wait for couple of months for new crack. The Dev Team released ultrasn0w 0.93 to unlock latest iPhones.

      My advise to you to use a fresh computer, it may don’t sound illogical, but I tried so many times and lastly I was successful installing each and every software to a new computer. iTunes, resn0w 0.9.4 and “iPhone1,2_3.1.2_7D11_Restore.ipsw.

      One more thing you can do, disconnect your internet connection, when you are installing iTunes and redsn0w 0.94 to a another computer to jailbreak. Connect your internet connection after the jailbreak is done.

      Hope you will be successfull this time.

  • Sameer

    Hi Simon,

    An emergency!

    All was fine, I was happily using my iphone2G, 3.1.3, unlocked using redsnow and today morning, while installing an app from cydia (IOS 4 3g theme) the phone suddenly shutdown and wouldnt restart. I tried restoring, it restored to 3.1.3, but it doesnt get unlocked using redsnow (I followed all steps, it doesnt work after step 13 ( after entering DFU mode.) It is strange because it worked a few days back (I successfully unlocked my phone) and now redsnow doesnt work. I’m sure it is because of the cydia app.
    I even tried restoring to 3.1.2 and unlocking using blackrain, but there was some asl.dll missing problem and it didnt work. Ive tried restoring it several times in 3.1.3 using redsnow and it doesnt work after that step. Am cusring myself for going to cydia to install the app.
    Please help.

  • Sameer


    Nevermind.. I learnt my lesson, not to install any random app on cydia.

    I tried many times it never worked, finally, I restored it to 3.0 it worked (redsnow), then I restored it to 3.1.3 and this time redsnow didnt give any problems.

    My phone is back to normal.

    Do post in case you come across any iOS4 hacks etc for 2G ers like me.

    Simon. I have two questions.

    1. I recently unlocked my Iphone 2g using Redsnow to use on a tmobile network and everything seems to be working corrctly. I was in the proccess of downloading WIFY under cydia and my battery died while doing it. when i charged the phone and fired it back up everything works great but cydia. in fact every time i try to access cydia it loads up and then kicks me back to the home screen. Do i need to re install cydia? if so how?

    2. I recently purchased a road trip iphone FM transmitter for my car. while placing my iphone on the doc a message came accross the screen that says you need to update firmware to run this app on your device. will this mess up my unlock? should i go ahead and upgrade the firm ware? I would like to use the ipod doc in my car but am unsure if this would mess up the unlocked phone on the tmobile network.

    Hi Simon,

    Currently I am using iPhone 2G with firmware 04.05.04_G. I followed your tutorial to upgrade to version 2.2.1 (5H11) along time ago and haven’t update it for a long time.
    If I want to upgrade to OS version 3.1.3, do I need to upgrade it to OS 3.0 first then follow the sequences 3.1.1 then 3.1.2 ? or I can upgrade it straight away from 2.2.1 to 3.1.3?
    Please advise.

    Hi Simon,
    I he upgraded my IPHONE 2G from 1.1.4 to 3.0 with your wonderful and easy guidelines. Everything is alright except Youtube. I cannot access youtube now.
    Any possibility that 2G- 3.0 can be upgraded to IOS4+ ??
    Your response is highly appreciable.


    • @Nitin,

      There is no way for iPhone 2G to upgrade to iOS 4. Apple has already ended the support of 2G from iOS 4 onwards. By the way, you may check out this post if you still have problem connecting YouTube.

      • Nitin

  • Sweetb

    Thanks you so much Simon! I tried heaps of times to jailbreak and unlock with RedSnow 0.9.4 and got stuck rebooting at the apple logo. Then I realised what I was doing wrong which was that I was using the original 3.0.1 firmware at the start of Redsnow instead of the 3.1.2 firmware. (I was on 2G 3.0.1).

    You’re a champ! This is the 2nd time you’ve saved my 2G 🙂

    @Simon – This post was simply awesome
    @ Iphone locked users like me earlier – I will explain the problem I faced and how I got it back.

    Note – I never upgraded iPhone in last 3 years when I jailbroken it first. That means I was not aware of most terminologies and procedures.

    Problem – I had jailbroken 1.1.4 iPhone 2g without knowing baseband and other details. I was planing to upgrade it to 2.0.1 for Microsoft Exchange Support but it failed during restoration. That means my phone was in DFU/Recovery mode without knowing what to do next. In order to resolve it we thought of upgrading my iPhone through iTunes. We were not sure which version iTunes is restoring. It restored iPhone1,1_3.1.3_7E18_Restore.ipsw but the phone was locked. None of emergency number worked to get me out from there.

    I went through lot of blogs and found following.
    1. For iPhone 2G, please select iPhone1,1_3.1.2_7D11_Restore.ipsw and not iPhone1,1_3.1.3_7E18_Restore.ipsw. This would take you out from “Unable to Recognize ipsw” error. Most of the times I was usingiPhone1,1_3.1.3_7E18_Restore.ipsw and was getting above error. After going through this blog it is resolved.
    2. Ensure to keep your iPhone switched off and connected to iTunes step above.
    3. During last step, in case your iPhone doesn’t reboot automatically , no panic. Disconnect it and do that manually.Bootlader might take 5-7 minutes.

    Since I was first time user things have really gone great but I missed all applications, contacts, SMS etc which is fine:)

    I am an idiot. My wife’s really mad at me. I tried to upgrade her old 2G Jailbroken phone to 3.1.3 – and bam! locked out!

    Looks like iTunes backed up the data tho…in library/….

    And seems like her home screen is showing her old wallpaper. so I am thinking all her data is still in there somewhere.

    Can we jailbreak 3.1.3 and still maintain or restore all her contacts, emails, and notes?

    Please help save my marriage!!!

    Just to inform you, I tried to download redsnow 0.94 window version using the link in your article [ How To Jailbreak iPhone OS 3.1.3 using Redsn0w for iPhone 2G/3G] Feb 8,2010 returned this message:

    404 Not Found

  • Cybertherea

    The link for redsn0w did return a 404 error, but I found it elsewhere on the web. The detailed, accurate step by step instructions were invaluable. Thank you!!!!

    I do not even know how I ended up right here, however I believed this submit was great. I do not recognize who you’re but definitely you’re going to a well-known blogger in the event you are not already. Cheers!

  • Generally I don’t read post on blogs, however I wish to say that this write-up very forced me to check out and do it! Your writing taste has been amazed me. Thank you, quite nice post.

    That movie where the chick puked green shit on the priest, masturbated with the cross, spun her head around, crawled backwards down the stairs, and wanted everyone to lick her vag…. What was that movie? Oh yeah! The Exorcist.

    Hi Simon
    I followed the steps and everything went as it should of done until I tried opening the cydia app then it just stays on “loading data” screen. Ive tried waiting for half an hour and nothing happens. I can press the home button and it will take me back to the home screen but same thing happens every time I try Cydia. Any Idea?

    • The newest available version for iPhone 2G is 3.1.3. Officially you can’t upgrade to iOS 4.0 or up. In case you’re looking for hack as a workaround, you may check out http://www.whited00r.com.
