Downgrade Baseband 06.15 to 05.13.04 Using RedSn0w 0.9.14b1

June 19, 2012 — by Simon Ng12


Not long ago, the iPhone Dev team announced an update of its popular jailbreak tool “Redsn0w”. The latest version allows iPhone 3G/3GS user to downgrade the baseband from 06.15 to 05.13.04. By downgrading, users who are originally stuck with the 06.15 baseband, can now use ultrasn0w to unlock their iPhone.

Here is the official release note of Redsn0w 0.9.14b1:

The iPhone Dev Team is happy to announce a baseband downgrade option in redsn0w for those who are using the iPad’s 06.15 baseband on the iPhone3G or iPhone3GS.

Typically you’d have the 06.15 baseband if you unlock with ultrasn0w but updated your iPhone baseband past 05.13.04. With this new capability, you can now downgrade specifically from 06.15 to 05.13.04 (even if you never had 05.13.04 on that device before). This gives you the best of both worlds: ultrasn0w compatibility and a normal iPhone baseband with full GPS and the ability to use stock IPSWs again.

Here are the steps:

Use the “Extras->Select IPSW” button in redsn0w to tell it which firmware version you have installed (new-bootrom 3GS users can usually skip this step but it doesn’t hurt for them to do it too).
Do a controlled shutdown of your iPhone (“slide to power off”). This step is very important to avoid mount problems when the ramdisk is running!
Go back to the first screen and click “Jailbreak”. Enable the “Downgrade from iPad baseband” checkbox, disable Cydia if you already have it installed, and click Next to proceed through the normal DFU ramdisk steps.
After the ramdisk gets launched and you see the Pwnapple running on your iPhone, you’ll eventually get to the “Flashing Baseband” step. THIS STEP TAKES A VERY LONG TIME to complete and there won’t be any feedback while its running. Please just let it be for the next 3-8 minutes! When the ramdisk has done its job it will reboot the phone on its own.

For those who are wondering if you can update your 3G or 3GS to 06.15 solely for the purposes of downgrading to 05.13.04, the answer is “yes” for 3G owners, and “maybe” for 3GS owners. The iPad baseband is not compatible with 3GS units manufactured week 34 of 2011 or later. If you have an iPhone3GS and if digits 3-5 of its Serial Number are 134 or later (xx134…), then you should NOT try to install the 06.15 baseband on your 3GS! It will brick your radio, preventing both the downgrade from working and normal iPhone software from using it as a phone! Be warned!

As usual, Redsn0w 0.9.14b1 supports both Windows and Mac OS. You can download it using the below links:

If you’ve tried out the downgrade, remember to leave us comment and share your experience.

Unlock iPhone 4 LogoiOS 5.1.1 was released few days ago bringing a number of bug fixes and HDR photos improvement. Jailbreakers and unlockers were asked to stay away from the update but I am sure some went on to update regardless of the warning. The main problem is for the unlockers as you can’t connect to your carrier which leads to a problem. In most cases, ultrasn0w could be reinstalled but since there is no update from the Dev Team, you now need to rely on ultrasn0w fixer 5.1.1. Read on for more details.

How To Unlock iPhone 4S, iPhone 4 on iOS 5.0 or Up

April 23, 2012 — by Simon Ng25


This is a big news for iPhone 4S and iPhone 4 users. Earlier, a Chinese iPhone hacker Loktar_Sun has released a solution for unlocking a jailbroken iPhone using Sam Bingner’s SAM (Subscriber Artificial Module) package. This SAM unlock method should work with all baseband versions.

I’m not able to test the method on my iPhone 4S as it’s a factory-unlocked version. However, the method has been verified on U.S. carriers by the iPhone Dev team member musclenerd as well as another iPhone blogger.

An Update about iPhone 4S Unlock

November 28, 2011 — by Simon Ng8


Unlock iPhone 4 LogoWhile Apple has already offered factory-unlock iPhone 4S in some countries, there are still many iPhone users waiting for an unlock solution that allows them to use SIM card from any carriers.

Not long ago, @musclenerd from the iPhone Dev team has announced on Twitter that the team is working on a promising unlock solution for iPhone 4S. The odd part, however, is the upcoming unlock solution will only work for iPhone 4S, the latest generation of iPhone. This may suggest the unlock solution depends on a hardware exploit which only found on iPhone 4S.

Temporary Unlock Method for iPhone 4S, Try at Your Own Risk!

November 19, 2011 — by Simon Ng1

Earlier, Gizmodo shared an usual method to unlock an iPhone. The method does not require you to jailbreak the iPhone. What you need is an original SIM card from AT&T and follow a set of procedures to unlock it.

As reported by Gizmodo, some users found the method works on their iPhone but some are not. I do not have the AT&T SIM card to test. I’m not sure whether this method works on all models of iPhone. So try at your own risk.
