I have been out of the jailbreak scene for nearly two years now but I recently bought an iPod Touch 4 because it was dirt cheap. It had 4.0 on it but I wanted to have the latest untethered/jailbreakable software (which is 6.1.2). I can't update via iTunes because that would put me at 6.1.3, so I downloaded the ISPW and tried to update via a shift-restore. Now I'm stuck in a restore screen loop and I keep getting errors. I tried a few things with Tiny Umbrella but I just kept getting various errors when trying to restore. I made a custom ISPW with sn0wbreeze. Tried shift-restoring that, more errors. I have no idea what to try next.
