I've got a couple old Androids (MotoX and something else ~2015ish) that won't boot due to dead batteries. There's an endless loop of:
- Charge to ~.25%
- Phone automatically powers on
- The boot process takes more power than the charger can provide, so it drains the battery
- Automatically powers off because battery is back to 0%
I've had them on the charger for a few hours and watched this process repeat over and over. Short of disassembling and swapping the batteries I've tried everything I can think of to get them to power up
- avar 3y agoI've never had a phone that refused to boot up with the battery fully removed and the USB charger plugged in.
- throwawayqc 3y agoYou could try: - booting into recovery -- find out which key combo might trigger that at power-on - booting into an OEM download mode -- "" - probably a cable insert + key combo - triggering the Qualcomm download mode -- "" That would load a different boot setup (maybe kernel, or just ramdisk, and whatever tools they added on top from that particular OEM), and that may allow you to charge. That can work sometimes.
- angry_moose 3y agoYeah, those fall in the "I've tried everything I can think of" category. They don't help, the devices die too quickly to make it into any alternate boot modes.
