I had previously replace the front and rear case. The phone was functioning except that the power button did not turn it off I replace the power and sensor cable, and now nothing works. When I charge the phone I am getting a beep-beep signal from the vibrator. What does that mean
After ruining a few screens, I am now convinced that there is no alternative to removing the display assembly for this particular repair. Sometimes I replace the cables, sometimes I just replace the button, but I always remove the screen! And for that I use a good amount of heat on the top but mostly on the bottom next to the home bottom, and a good suction cup.
Did you take out screen when fitting button as the screen cables are not ment to be bent forward. The screen needs to come out when fitting power flex If so then you have damaged the screen.. Bonging when in charge indicates a damaged screen also.
