REAL solution for 3Gs Downgrade to iOS 4.02!
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.

These instructions are no longer valid. Apple is not signing iOS 4.0.1 anymore. If you do not have your 4.0.1 SHSH on file already, you can not restore to 4.0.1.
The preceding forum post has been brought to you by the letter "N" and the number 42.
iPhone 4, 32GB (iOS 6.1.2 | evasi0n | SHSH: 4.0 - 6.1.2)
iPad 2 3G, 64GB (iOS 6.1.2 | evasi0n | SHSH: 4.3 & 4.3.3 - 6.1)
