How to downgrade iphone 3gs OS 4.0 to 3.1.3?
I downloaded 3.1.3 IPSW and put my iphone into DFU mode. When I chose restore, windows pops up “verifying iphone restore with apple”. then another window pops up telling me that my device is not eligible for a restore. HELP!
As you read this, there is no-way to downgrade your Iphone 3gs on 4.0 OS back to 3.13
You’re going to have to wait for the new spirit software update and the new snowbreeze 2.0 which they should be coming out by the end of this month. I hope, I got myself a 3gs also that I need to get it jailbreak and unlock. Good luck.
Sincerely,
