NOKIA LOGO + GEARS + Dead battery icon

[monstervinvin]

device: Nokia Lumia 1520
Can anyonehelp me? I'm really desperate.

I did everything from downgrading to 8.1 then
downloading windows insider app.

I am in the fast ring and got two updates.
> the latest build for windows10 mobile 100136 and the 8.1 reboot update
> i charged it to 100% = checked it on my status bar.
> now the I pressed install now then the Gears started spinning.
> it gave me a few PROGRESS then suddenly it went to the NOKIA logo and displayed a BATTERY low icon with a PLUG on it...

it keeps repeating like that I even have it plugged in all the time

The battery might be loose. I dunno how you could fix it but this used to happen to my 525 almost all the time but was easily fixed by removing and re-inserting the battery.

I suggest you take it to the nearest care center since the 1520's battery is non-removable
