Ok, I just downloaded this new app from cydia called "Boot Logo". I have an ipod touch 2g 2.2.1! So, I selected an image, then tapped "Flash Logo", then "Flash". Then in two seconds, my screen went black. I've tried some things but they all failed: 1. Put it in DFU mode(hold power and home button for 15 seconds then released the power button for 10 second.) Then try to restore in itunes and itunes didn't recognize it but my computer said, "USB Device Not Recognized"! 2. Tried to charge it and nothing happened. If anyone can help me, please tell me! DO NOT POST ANYTHING IF YOU NOT KNOW HOW TO FIX THIS!!! I HAVE tried iBrickr, and ZiPhone!
