I bought my iPod touch 3G a few months ago and decided to jailbreak it using tethered jailbreak for 4.3.5(using 4.3.4). Everything worked fine and I made sure not to turn it off until I left it with a friend of mine who powered it down. Ever since then I've been stuck in a recovery loop. I tried iReb which says tethered jailbroken devices cannot be repaired, i tried Recboot, fixrecovery, I also tried tiny umbrella but the fix and exit recovery buttons were greyed out. I cannot even recover using itunes as it is always giving error messages. Any help resolving this would be greatly appreciated.
