Help Battery Problem!? Suddenly shutting down at 100% level

Hi guys, i dont know what the root cause of my Nexus 10 that suddenly shuts down even at 100% battery level.. Then if I'll turn it on again it will only boot on the swirling four colored circles, then will turn off.. if i plug charger to it, it shows charging but at a drained battery level.. :(

I would like to know who also experienced the same issue and have you tried to resolved the problem? how?

What is this actually, a system/software-sided battery malfunction? or is it battery-hardware related?

If this is a software-related maybe i could just re-flash and wipe everything to my nexus 10, to refresh the tablet,. If the battery itself is the problem, im in big trouble.. as the nexus 10 battery replacement is kind of hard to find..


I dont know what to do. Please help save my nexus 10! Thank you in advance guys! :fingers-crossed:

Have been using 4.4.2 Alliance Rom for a year - suddenly stops at first logo

I've been running rooted with Alliance Rom build 32 for about a year with zero problems. The phone battery ran low last night and the phone turned off. When I turn it on it stops at the first logo. I can't get into Philz
recovery. It will go into downloader mode. I tried using Odin to revert to the stock MJ9 I started from when I used Casual. It flashed successfully (stock pit and MJ9) but still gets stuck at the the first logo and won't go into recovery.

SD card is removed. I haven't made any modifications to the phone for the past six months except adding a few well known apps from the store.

Any advice on how to get back to where I can load recovery and proceed to reinstall would be greatly appreciated.

PS.

I would have bought a new phone last year but it seems all the ones I like are bootloader locked. I can live without the stylus (would love a new note though...). Any recommendation on a replacement for the Note 2 would be much appreciated.

[HARDBRICK?] Galaxy S4 Mini Duos suddenly dead

Hello
My galaxy (i9192) just went dead. No custom roms or anything. It was working ok until battery discharged. Now it has 2,8V and wont charge.
Ive tried debrick images found here but none of them worked. Only "life sign" form this phone is QHSUSB device that showed up as Qualcomm HS-USB QDLoader 9008 after drivers installation.
Do you have any suggestions what else i can try?

Thanks in advance :)
