My wife tried to jailbreak an AT&T iphone4/iOS 7.0 using greenpoison RC6, which doesn't support iOS7 or even 6. Now the phone is looping on the Apple logo, even when I manage to put it in recovery mode, and try to restore it using itunes, the restore never work, and give different errors. I managed to put it in DFU mode and tried tinyumbrella with itunes, still no go. I tried latest redsnow, selected iOS6.0, and tried to jailbreak, the process completed on the computer and I get the msg stating the rest will take place on the phone, but the phone reboot on the looping Apple logo.
Anyway I can fix that phone?
