Thank you for your guide. I’m almost finished but before closing the screen to the frame I’m testing whether the touch works. But on the unlock screen all numbers but 1, 2 and 3 work. What could cause this problem? I have installed the kapton tape on the replacement screen.
Did you unhook the battery before you took off the screen and reinstalled it? Unhook the battery and disconnect the screen connector and get a magnifying glass and see if the pins were damaged. If they are ok on both connectors than take a qtip with a little alcohol and clean the connectors then brush them off with a soft brush. Reconnect and try it again
