J3 won't turn off

[atorreaa]

Hello everybody, it's been a couple of month now since I stopped using my J3, because it won't turn off anymore, so my battery drains quickly. I want to give it a last try, so here it goes:

1. When I try to turn it off (turn off o r sleep mode) it just exits the main screen and shows "Battery Full" screen. Anytime I press the "Play / Pause" button it quickly turns on. That's why I know it remains powered on all the time, otherwise it should show the usual J3 splash screen at startup.

2. I managed to turn it off, but the process is weird. First, I have to plug the player on a PC using the USB cable, then unplugged it and connect it to a external USB battery (5V and 500 mAh). After that it turn off (it turn off inmediately after connecting to the external battery).

3. I already tried formatting (with the special tools listed on this forum) and tcctools, but nothing happens.

Please, if anybody knows something about this problem, just let me know.

Thanks guys!
