Had my triple bypass in Sept. Offline for a long time.
So DING DING DING my APPLLP 9 boots now!! Thank you pablo11!
The firmware you sent me worked.
Followed:
Installed the driver from the Flashing Tool onto a Win 10, then ran the flash tool and downloaded only after finding the scatter file from pablo11’s firmware for my device.
This advice got it to boot (after flashing) DM100 or LEMFO LEMT Hard Factory Reset or Boot into Recovery/Safe Mode
adb shell am broadcast -a android.intent.action.MASTER_CLEAR
Now 
to see if it will charge from 1% overnight.
