I was running 4.2.1 on redsnows tethered jailbreak and the jailbreak worked fine for a long time then yesterday it just wouldn't turn on. So I tried to restore it and it worked the first time but once i jail broken it and then synced it the ipad crashed and had to restore again. The second restore will not finish and is stuck on that last half inch of the restore bar( I have retried the restore a couple times). What do I do? thanks for any help.
