I had a difficult time removing the battery. The installation went okay after that but putting back together was a challenge for my "old" eyes. I used a table magnifying lamp to get the screws on the end of the screw driver and the for the placement of the screws. I had trouble with the cables but used my fingers to feel when they snapped in correctly. Buy phone rebutted and it said it had 76% battery. Everything looked fine until I needed to recharge it. It will not take a charge & now it just reboots continually (as others have said). I took it apart again and checked everything. Another hour taking the screws out, checking the cables and putting it back again. Same issue. I'm seeing that others had a bad battery. I didn't put the old battery back in as it bent coming out and I don't want to take a chance that it was damaged. So now- do I take it apart again and send the battery back? Any other suggestions??
