I replaced battery with a battery that screwed up my phone
So i ordered a battery for my Iphone and replaced the current battery in it. As far as doing the replacement it went very smoothly. When everything was put back together I started up the phone and there were vertical bars across the screen and there was nothing about the phone that was working at all. When I took the phone back apart, i read the battery writing and both the WHR and the APN didn't match. It was then i realized i was sent the wrong part. I put back in the old battery and there was no change. Just bars across the screen. Is my phone salvageable? If so how do I go about fixing it or is there a way to at least get my files off of the device?
