iPhone 4 won't turn on (old and new mobo)
I was fixing an iPhone 4 and i think i damaged the motherboard (shorted it). The thing didn't blink afterwards, pluged in it was only chirping (no display). I tested the battery, which worked on another iPhone, a different battery had no effect.
I got a new motherboard now and it still doesn't do anything. There isn't even any chirping.
What else can i try/change?
