What’s the problem with my phone? It shows the Apple Logo but it shows a black screen after. What happened?
You should probably replace the water damaged motherboard.
You probably did something wrong when putting the phone back together.
Why did you follow a teardown to replace the LCD display? I thought that iFixit has a LCD display guide for this phone.
You should probably plug in the phone. I’m only saying this because most Android phones turn on when you plug them in.
