My friend got two iPhone 3GS (software is 4.1 jailbroken, second phone is at 4.0). One is jailbroken and the other one is not. The jailbroken one, in cydia it shows that it could be upgraded to 5.1 and 5.1.1.
I tried helping him to upgrade his phones. Using redsnow Ver 0.9.15b3, I tried upgrading both phones to 5.1 and 5.1.1. The redsnow stopped working after few seconds after the phone ran on DFU mode. Then an error showed - "Redsnow stopped working, Windows is looking for solution."
I tried it on at least 3 laptops with the same error. Any help would be highly appreciated.
