Some iPhone users have reported that Winterboard doesn’t work after jailbreaking with blackra1n, the 30-second jailbreak tool developed by GeoHot. iPhone just can’t change theme in Winterboard.
So, what’s the problem and how do you fix it?
A reader (thanks, Rawsole!) has sent me a tweet for the possible fix. It looks like the problem is due to Icy and it’s suggested that not to install Rock/Icy to avoid the issue. If you’re following the jailbreak guide to install cydia only, you shouldn’t have the problem.

Alternatively, if it doesn’t work out for you, I suggest you to use PwnageTool 3.1.4 to jailbreak your iPhone again. iPhone Dev team also addressed this blackra1n issue on its blog:
For the early adopters who ran blackra1n and are having problems with mobilesubstrate, winterboard, diskaid, or ifunbox, you can install a custom .ipsw from PwnageTool to fix these issues. That’s because all jailbroken devices accept a custom .ipsw created by PwnageTool. (However, if you ran blackra1n on a 3G or 3GS that means you updated to stock 3.1.x, and the carrier unlock is now out of reach. We’ll continue to work on a carrier unlock for the latest basebands, but the timeframe for such an unlock is unknowable.)
Do you experience this Winterboard issue after blackra1n jailbreak? Let us know if the solution works out for you.

winterboard not working in 3gs 3.1 pls help/
If Winterboard is not working after Blackra1n, Cydia, and Icy then you can restore your phone and make sure you install Cydia ONLY! DONT install Icy!
I made that mistake and I really didnt want to spend those long hours restoring my phone so I reinstall Cydia from Blackra1n and reinstalled Winterboard and it works again.
The error is not caused by icy itself, it is caused by DPKG the unpacker causes extraction errors.
All you have to do is to reinstall DPKG and reinstall the apps and dependencies again. MobileSubstrate must be reinstalled too.
@Islam Adel,
Great advice! Thanks.
thanks bro
How do i re-install DPKG??
that did the job. it worked on my Iphone 3gs 3.1.2 I had icy, rock and cydia all on the phone. I restored my phone and used Blackra1n to jail break the phone. installing only cydia, fixed the problem. thank so much!!!!!
