Did not work for me. It is fully charged and shows 100% charged. WhenI power it up it goes to the 2nd LG screen with the orange emblem. If It will not turn off without removing the battery.
THis is from another Message Board. I am copying and pasting a solution someone else had. So hopefully this work.
Literally JUST fixed my problem.
Left it plugged in with the stock Cord/USB Charger for 4 hours, came home and it was 100% Charged screen.
But then, it wouldn't boot past the LG Screen.
I then reseated the battery, popped it back on the charger and now it's ON and working.
That resolved the problem for someone else. Let me know if it works for you!
