Boot loop after battery replacement
So someone dropped a phone off to me telling me they are stuck in a boot loop. I tried restoring and updating the iPhone and the iPhone disconnects while trying to do this. The customer then told me he tried replacing a battery and the first time the boot loop would go to a red battery and restart. He replaced the battery again and now it just shows the apple logo and restarts. I put the original battery back in and it still happens. I have been in revovery mode, DFU mode, I have taken the screen off and tried, unplugged the battery and plugged back in, unplugged the battery and held the power button dow for a while, tried holding home and power and I also tried using other software. When it tries to install or do any task it disconnects. It gives the error 4013.
Has anyone ran into this before? Any idea what could be done to fix it? Im not sure if this could be pry damage from him replacing the battery himself, but home and power do work.
Any help is appreciated!
Is this a good question?
