N7 won't stay on - Nexus 7 Q&A, Help & Troubleshooting

I just just updated to TWRP 2.3.2.1 flashed the 4.13 bootloader and flashed scroslers 4.2 rom, while Google Play was restoring my apps the screen started flickering and there was white noise coming out of the speaker and then the screen just went blank. The only way I can get it to power up is to plug in the USB cable, doing this it powers up on its own and boots in to the ROM and then in a minute or less I get a flickering screen and the unit shuts down again. I have tried to get into recovery and it always shuts down before recovery starts. Any ideas?
Edit: Got into recovery did a complete wipe again and reflashed the ROM but the N7 shut down again as soon as TWRP started installing the ROM.

Try the nexus 7 toolkit if you can get your nexus to be on the time you need to flash stock and after that see if it remains on. If not, lock up and get it fixed

Nexus 10 won't boot - solved

I tried (clean) flashing a droid concepts build over on droid-hive a little while ago and everything went ok when flashing. I tapped reboot system in twrp and the screen went black and didn't boot. I can't get it to boot consistently either into the os or into fastboot. It'll occasionally let me into recovery and I tried restoring a backup and also just rebooting from recovery and it won't boot at all. When it is plugged up, it'll show the charging icon when I tap the power button like it does when the screen is off. I've tried everything I can think of. Any help would be appreciated. Thanks.
Edit - I finally got it into fastboot and I flashed the stock google image. Its working now.

[Q] Google icon bootloop

Then I turn on the phone google logo appears, stays for few secs then phone turn offs, after a sec it turns on again with a google logo and it goes like this infinitely. I can't get into recovery, because the same happens if i click Recovery in fastboot. It fixes after charging the battery a bit, probably my battery was dead before, but today I fully charged phone, tried to root my phone so I unlocked bootloader and when I needed to factory data reset, in recovery mode i got red triangle, I turned the phone on and off and got this bootloop again.
Any ideas on how to fix?
EDIT: Finally i turned it on, rooted the phone installed franco kernel, hybryd radio, and ParanoidAndroid, with bad gapps, reinstalled good gapps and now the phone does it again, except it doesnt restart, just freezes at google logo screen
After bootloader is unlocked flash a custom recovery through fastboot, boot to new recovery, wipe all, flash ROM of choice
If this doesn't work then wipe all in fastboot and flash ROM through fastboot, but a working recovery is nice to have

N4 Semi-Brick? Can I recover?

Hi,
I have a N4 that was new but the screen cracked on it and eventually the battery died as well (wouldent hold a charge). I got the battery and screen replaced but as soon as this happened I could not boot into any rom. I had twrp installed but everytime I tried to install a rom such as CM it would install but would stay stuck in the boot loader. I then used NRT to try and kick it out of bootloader and I tried several different stock firmwares, 5.01, 4.4.4, and 4.2. The only rom that was able to get past the boot animation was 4.2 it went to the welcome screen to choose a language but I could not select anything via touch screen. In that screen I could lower and raise the volume via the rockers and turn the screen on and off. I had twrp installed and the touchscreen worked fine in twrp. I also tried this: http://forum.xda-developers.com/nexus-4/general/tutorial-how-to-unbrick-n4-t2347060 and it also let me get into the developer firmware but of course it is encrypted so I could do nothing. The phone has not had contact with water etc. Do I have any other options? Can I get some type of diagnostic such as logcat or something?
Thanks!

Nexus 10 powers off during boot screen

Hey all,
Just some details before the background.
I was running a stock with a unlocked bootloader for a while now. I basically only use my nexus now to watch netflixs and HBOgo. Got the tablet over four years ago.
This morning after it's nightly charge I went to unlock it and it froze up. I rebooted it, noticed the date was off (Jan 1st) and froze after I unlocked it. Reboot again, it made it to the screen where it was optimizing my apps but the screen starting flickering and having artifacts, and powered off. Now it will power itself off 5 or so seconds into the boot animation.
I've tried going into recovery via the bootloader but when I select it and hit the power button it just turns it self off. I then used the nexus toolbox to reflash a stock rom (along with a factory reset), and TWRP. I tried booting up again and same thing. I then went into TWRP and start troubleshooting, but the screen is starting to flicker and have artifacts, then powers off.
Is the hardware dead on this?
Sorry for the jumbled mess of details, i've been bouncing around trying to troubleshoot/fix this.

PIT files
My nexus 10 has the boot loop problem and I think I have been left with the only option of Re-Partition but I need the PIT file. Can anybody help or provide this file?
I have tried everything else (fastboot, adb, temporary custom recoveries, Nexus Root Toolkit) with no success.
Is the battery original? If so, it's possible the battery could be reaching its end.

Nexus 4 won't power on, fastboot recovery mode accesible

Hi All,
I am having a similar kind of problem like many others already stated but mine one is a bit unique.
My phone will power on, google logo appears, it starts to boot then nothing happens....it keeps on restarting the sequence but never completes the boot process. I can access fastboot, recovery mode but the phone itself doesn't start.
However if I keep it plugged to my wall charger it completes the boot process and I can access my phone, but if I unplug and start using it just shuts down randomly (1 min-30 min).
I have wiped cache, restored to factory already. Currently I am running 5.1.1 with no modification at all.
Any suggestion to bring it back to life is appreciated.
Replace the battery and I think it will work without any issues.

Most likely the battery is dead.
