I have a jail broken iPod touch 16 GB 2G running 3.1.2 firmware. I was recently updating some App Store apps via WiFi and it froze. I did a force reset (hold power and home buttons until reset) and ever since I haven't been able to turn it on. Every time I try it shows the boot screen with the apple for roughly 30-40 seconds and then shuts off again. I've been able to put it into recovery mode but REALLY REALLY want to avoid a full restore. Any suggestions?
