I have an iPad (64GB WiFi running 3.2) that was jailbroken. In Cydia I was notified of an essential update. I allowed it to continue and the iPad rebooted. However it didn't restart, I just got the Apple logo and a rotating arrow. Waited a while (30 minutes) but it didn't continue. In attempting to restart the iPad I managed to get it into recovery mode, iTunes says it needs to be restored. So iTunes downloads 3.2.1 and starts a restore. This seems to proceed normally but then stops just before the bars both in the iPad and iTunes get to the end. I waiting overnight but it didn't complete. Anyone have any bright ideas on how to recover it?
