Why did it go into "restore mode" replacing the battery?
I have the same issue with the addition that it went into "restore mode" after the battery replacement and stayed in a restore mode loop. with the buttons not working the only way I can get it out of the restore mode loop is to unplug it from the computer at the end of the restore when the phone powers down to restart. at that point it will power up properly and allow me to to an icloud backup restore and use the phone almost normally. but as I said before, neither the home nor the lock button will work. I reopened the phone but can't find any physical damage to the board, not even a scratch or dent. I fix iphones regularly and have never had this issue, and unfortunately/fortunately when I do finally run into this issue it is on my own phone lol Anyone got a picture of the component that is responsible for this phenomenon?
Is this a good question?
