Apple logo cycling on and off after battery replacement.
I have replaced my Iphone 5s battery per your video instructions. You left out the part about keeping track of screw sizes and non-magnetic screw. When I power on, the Apple logo appears for 1 minute and ten seconds and disappears for 3 seconds. This continues constantly and cannot be turned off without opening the phone and disconnecting the battery. I have tried to boot with the instructions on your website (which is where I found out about the screws). No luck. I noticed that the battery I ordered from PhonePartWorld.com is part number 616-0728 and the original battery part number is 616-0718. On-line research shows 4 part numbers for the 5s battery and both are supposed to be okay. Is this true? Are you able to tell me what may be wrong? Thank you.
Is this a good question?
