Phone won´t start. Frozen on apple logo
I have an iPhone 5S in for a repair. The customer accidentally put a wrong charger in the phone, and the changing port broke.
So I replaced the charging port and the phone turned on when I put in the charger.
But, it´s frozen on the apple logo.. It won´t boot properly. Once in a while it gets a white screen or a black screen..
Does someone know what might cause this issue?
Is this a good question?
