Hey. I've tried to update my Iphone 4s with ios 6.1, jailbroken with Evad3rs Evasi0n Jailbreak. I want to update it to ios 7.0.6. I have downloaded a ipsw file. I tried a lot of different guides and it always ends up with a error message. Changed host files, turning of firewall, DFU-Mode, TinyUmbrella, Older versions of iTunes. In the end i tried to update to ios 8 through iTunes completely, even that ended up with a error message. Anyone have a soulution for my problem? Anyone now a way to do this without iTunes? I dont remember all the error messages but some of them was, 4006, 11, 1601. Sincerely.
