Boot loop after replacing battery
I recently replaced the battery (replacement battery from iFixIt) in my iPad Air 2. After the replacement, the iPad will only turn on when connected to the charger, and even then it stuck in some sort of boot loop. It turns on, displays the Apple logo for 1-2 seconds, turns off, then turns back on, and repeats this loops indefinitely.
I have read online that this is the “loop of doom” and it is the result of the battery not having enough charge to boot.
I have had it connected to the charger for 2 hours and it still in the loop.
