My iPod has been jailbroken for around 2 years & has been working fine, until last night. It randomly went on to the blank screen with the apple logo. I tried using redsn0w to reboot it, & on redsn0w it said "done" but the iPod just went to a black screen & wouldn't do anything. So I tried to jailbreak it again, & it got about half way through the process then stopped on "Waiting for iPod touch 4G", but the iPod doesn't do anything! It's just stuck on a blank screen. It goes into DFU mode fine, & also recovery mode. I tried to reset it by iTunes but it came up saying "This ipod could not be restored. An unknown error occurred (3194)". I also let it die last night hoping it'd just work this morning when I turned it on, but nope that didn't work either. I don't know what to do! If anyone has any suggestions they'd be much appreciated! I don't really want to have to buy a new iPod.. Also before anybody says "this is why you shouldn't jailbreak blablabla", just don't. If I get this fixed, I'm going to keep it UNjailbroken. Pleaaseeeee helpppp?
