Won’t turn on after battery replacement
After battery replacement it won't turn on anymore. No reaction on the screen, no haptic feedback - no vibration, phone offline in "find my device"
What I tried:
- plug in to charger
- long press power on
- long press power on + volume down
- even tried to reconnect the old swollen battery which worked before, but with the old battery which worked an hour ago it's also dead.
- I fully reassembled the device in case it does some integrity checks before booting, (Fingerprint sensor, etc.)
Any ideas what I can try?
I did not notice any breakage during replacement, nothing had to be forced. I have no idea what to try.
Is this a good question?
