Why doesn't my x4 boot up?
What is there in the back of a Moto X4 that prevents phone from booting up? I've replaced motherboard, charging port, battery and phone still won't start. When I put the same parts into a Moto X4 with a cracked back, everything works, but not when I put them into the back I want to use - its in perfect condition. HELP!
Is this a good question?
