I replaced the phone screen, and forgot to unplug the battery before replacing the screen. At first there was no display but the phone lit up. I managed to get the phone on, but now it’s displaying 2/3 screens. The bottom ones are copies of the top screen. The top screen is the actual screen. It works and the touch works on all parts of the screen, and it’s super jittery everywhere on the phone. Is there anyway to restore this phone thanks!

Open up the phone one more time and disconnect battery and then try to reconnect/reseat propperly the 2 flex connector of the screen on the logic board. Before closeing the phone check the screen if it works. Hope this will help/
