Not able to downgrade...
I have an iPad 2 gsm on ios 5.1 and have shsh blobs for 4.3.3 . I tried to follow the guides on internet to downgrade it. It says me to enter pawned DFU mode but redsn0w shows an "No operations supported for this device" error. If I try to restore it normally it shows an iTunes error 1 and goes to recovery mode after restoring. Even fixing recovery mode through TinyUmbrella doesn't work.
Thanks in Advance.
Take a look at this tutorial: http://www.ipadforums.net/jailbreaki...hsh-blobs.html
Hopefully, by following the steps, you'll be able to downgrade to iOS 4.3.3. Good luck.
