[Q] Nexus 7 won't turn on

My Nexus 7 has been freezing on me lately, so I figured I should back it up. During the backup it froze at 60%. After a reboot I attempted to backup the most important data but titanium backup kept failing. After two failed attempts the tablet powered off by itself. It would not boot past the Google logo. I was able to get to fastboot mode. While in recovery I did a factory reset. After the factory reset the Nexus went in to a boot loop. It displayed the Google logo, then reset. I could still get in to fastboot mode and it froze once more while in fast boot mode. I powered it off and now it does not power up. The battery showed 43% when I was doing the backups, but I thought it might of been wrong so I recharged it for two hours. It still will not boot up. If I have the Nexus plugged in to my computer and turn it on I can hear the sound that a new device is connected but almost immediately the sound for the device being disconnected plays. I figure the flash memory has failed while writing to it during the backup, but the new device sound seems odd. It is under warranty and I will probably have to RMA it. But before I that happens I wanted to check with awesome xda community and see what you think.
Has anyone experienced this before? Any idea what went wrong?
Thank you for reading my post.

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.

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.

Repeat intermittent boot loop

hi all,
Just come back from holiday and SM-G928F edge plus (european model) battery was completely flat.
I charged the mobile and booted it up, loaded into Android then sounded like a lots of notification alerts then phone made a loud buzzing noise and crashed/auto-reloaded.
Since then it had gone into a boot loop. Tried holding power and vol down to reboot phone. Initially this function worked then no longer worked. Phone still stuck in boot loop...
Could not get into safe mode (hold power and vol down then release power)
Tried in recover mode (hold power, vol up and home), tried clearing cache took ages about 1 hour, also tried the format option, rebooted system and still boot loop..
Tried going into Odin mode (power, vol down and home) , used ODIN s/w and installed the latest XER version firmware, got success message but still boot loop...
Interestingly when I left it to constant boot loop, eventually it booted up Android now. However once I start using the mobile it intermittently reboots the mobile and then goes back into boot loop again...
When I did manage to get into Android I tried using an app to check the mobile health, strangely I notice it said I only had 1gb ram spare and the rest was used when mobile was factory reseted and I didnt expect so much RAM in use. During stress test mobile crashed and gone into boot loop again...
I am not sure this was affected by an auto update that may had gone wrong.
I don't root, just used stock firmware.
UPDATE:
Left mobile in boot loop until battery went flat, fully charged it and now can get back into Android. But it started to auto update some app and then auto rebooted/crashed and went into boot loop again.
Please help.
Thanks

Is there anyone who can help me please?

Rn7 global died all by itself

The phone rebooted by it self, no firmwareupdate going on, just random reboot.
Got stuck on redmi logo.
Could reboot and get fastboot, but could not flash original fastboot rom, got errors. a normal reboot gave only redmi logo.
Now the phone is out of power, not taking charge, not powering on.
Anyone have any solution for this problem? Or any tips? The phone is stone dead

Not sure if this will help...
here's my random reboot thread and fix

Well, i have no simcards or sd-cards inserted.
And its not charging or turning on. volume up and down + power is not making any results.
The weird thing is that it said "redmi" on the display for about 24 hours draining the power, and after it died out of power i'm unable to do anything with it. its basically a brick.
This happened totally random. just a spontaneous reboot into a never ending redmilogo.
During redmilogo i had the posibility to get it into fastboot by rebooting it, but mi flash would not accept the phone. so another reboot into regular boot ended in infinite redmilogo again :|

Your phone's bootloader unlocked?

Nope

Did you try keeping it charged for a while? Device might not show any sign (charging indication) but the battery will get charged eventually (I guess).

Charge it well and try to SIDELOAD that FASTBOOT IMAGE via PC..

It loooks like its bricked all by itself. i left it in charger for days.
I got contact with the phone with mi flash, but it has gone into some authentication mode with the flashing, so i'm not possible to reflash rom without authorization.
Read about this on reddit, and it seems like a dealer has to look at it.
