i have see many people asking for Downgrade 3Gs when it already oniOS 4.02.
IF YOU HAVE NOT SAVE YOUR SHSH.
1- you'll need this TinyUmbrella download here The Firmware Umbrella
2- Open up Tiny Umbrella -> tick Advanced Option -> Select 3Gs 4.01 -> Cydia and Click SAve My SHSH
It will give a message say " Successful SAVED " something like this from memory.
With BOTH Already saved or JUST SAVED USE THIS STEP TO RESTORE BACK TO iOS 4.01
3- Start TinyTSS Server.
4-iTune - Back up you Data (if needed) -> then put iPhone in Recovery Mode (you should know how by now, if not use the search button) and Shift/Option, Click RESTORE and Select "iPhone2,1_4.0.1_8A306_Restore.ipsw"
Just relax and wait for the iTune to finish off.
and Start you JB and Unlock.
I have DONE a few by this method, 100% success
Hope this will help. and if anyone here want to add comment or correct me please do so.
