Posted by stlpaul,

Rubber band worked for me! I had a power meter attached. During the process, there was a 150mA pulse approximately once every 10 seconds while the power button was depressed. After about 5 hours, the LED turned into a fast blinking red light, and charging rate increased to 500mA. When I saw this, I removed the rubber band. A short time later, the screen turned on, Android booted and charging rate went up to 2000mA.

Useful details

quite easy...too late for me but good to know 😄

I measured 3,20V on the battery connector at red flashing state, is this voltage the very low battery state ? I thought it was more around 3V, but probably depend on battery model/technology

Also I inject 4,1V direct on the battery connector, and in about 30s I had 5% battery, so this trick is very good !

Did you have the red notification light flashing about once per second when trying to charge it?

This seems to be the status of mine too. It's drawing constant 50mA, but even after leaving it for 24 hours, it will not boot.

The rubber band trick is also NOT working for me. I tried several times, leaving it for over 24 hours for one attempt. So I'm guessing you had to disassemble and connect a bench PSU to the battery connector?
