So I followed this procedure, tore the foil on the back of the screen as I was removing it. Not sure if that’s an issue, but after reassembly, the phone will not turn on. The screen is black occasionally flickering like it’s trying to come on, and the blue LED is on constant. None of the buttons work, even to try to force it to shut down. The only way to get the LED to turn off and the screen to stop flickering is to unplug the battery. I replaced the battery and the daughterboard. Haven’t applied any new adhesive yet, so I can still easily disassemble the phone. Any advice?
