Guys I am on 5.0.1 Jailbroken & everything was going perfectly. I did not install any new app or cydia tweak.

I was replying a friend over sms, my phone got stuck. I waited for few moments & turned it off [home + power button]

Since then it is not turning on & it is stuck on Apple logo. I tried multiple times, shut down & start, still no vein. I also connected to iTunes thinking it might be in some DFU / recovery mode, but iTunes just gets crashed OR stops responding when I connect my iPhone.

Please help me !

I have saved them using Tiny Umbrella & even on cydia I remember pressing "make life easier" or something... But I thought I cannot downgrade since Apple stopped signing it. Isn't it ?

Okay I will google & find out... thanks for the help mate ! And btw why did u downgrade ? for untethered JB ?

I also like to know one more thing, my friend has a iPhone 4 locked & using Gevey SIM. Can he upgrade to 5.1 preserving baseband & have the unlock working ?

Yes...you can update to 5.1 and preserve baseband...do your homework on" How To" as you will only have one go at it...


I own an iPhone 4...I used Sn0wbreeze v2.9.3(using the iFaith tool within) to build a signed custom 5.0.1 firmware... takes a bit of time to build the firmware but downgraded first time with Sn0wbreeze..:)
FYI.. there is a stand alone version of iFaith which I used initially but kept getting error37...the fix is to use the iFaith embedded in Sn0wbreeze...

Some tips I found useful if you use Sn0wbreeze...make sure iTunes host files are reset and pointing towards Apple servers and not Cydia...
No need to use tinyumbrella once you have created your signed custom firmware..make sure you use the iReb tool(again built into Snowbreeze) to get you into a pwned DFU mode...
downgrade should go like clockwork:)
