Okay, I bricked my ipod nano by doing some soldering for a battery charger wrong, and now it's bricked. It's not able to charge anymore, and when it's connected to 5V USB power, the back of it get's really hot.
I want to exchange the nano's battery with some other 3.7V power source and then connect it to a PC, with a cable with a disconnected 5v power cable - just the data cables.
Could this work?
