Experienced immediate problem: there is s strap going from the home button to the screen, about 1-1/2 inch long. After removing 3-4 screws I saw no way to disconnect it from either end. My daughter came to help get the screws back (my 70 years have problems with very tiny screws). Slid a piece back and the strap came free of the home button ares. Screen could only open then 75-80 degrees. Tapr tore. Pried battery out. Replaced on original sticky tape. Restarted fine and about to recycle the charge. Thanks for the kit and all. But 6 demos and 3 inatructions never mentioned this strip! So careful opening it up, please!!
