White vertical lines and unresponsive touchscreen
Hi, I wanted to replace my rear casing, however after looking at the battery, i noticed that my adhesive strips are to short, so i couldn't pull on them to get the battery out, instead of heating up the adhesive I gave up and decided to reassemble the iphone. I plugged in the battery and reattached the screen flex cables. When I booted it up, a lot of vertical white lines appeared and the touch screen became unresponsive.
PS (it's currently on 39% charge, I haven't tried to replug the battery and I haven't tried to clean the connectors)
