My jailbroken iPod 4 is stuck on the apple boot logo, it randomly gets darker and then brighter again. It happened because I tried installing a bunch of stuff from Cydia at once and then this happened after I tried to respring. Normally, I would restore it, but I can't because I have to sync it to iTunes, which I can't do because it needs me to put in my password on the device, which I can't do. I tried putting it into recovery mode, but it is completely unresponsive in this state. I can't think of any information to add, but if you think you can help and want to ask a question go ahead.
