hello everybody, i'm so glad i found this forum.
i have a jailbroken ipad 2 4.3 version , and i don't want to use it as a jailbroken anymore.
so i tried to upgrade it to the newest version 6.1.2, but with no luck, everytime i finish with that error 1603,1604.
so far, this is what i tried :
* restore the ipad on 2 different computer, using all usb ports
* uninstall and reinstall Itunes to the newest version
* enter into DFU mode and download manually from GETIOS the 6.1.2 version and try to restore it with SHIFT + RESTORE
* change cables
* remove\add the apple lines from hosts file
now i'm stuck with an ipad that don't even come up, sometimes when i charge it for long time it shoes the recovery mode ...
please help me out, what else can i do ?
