I can get into the boot-loader but it doesn't help at all and now it does not want to turn on at all

4.2 update fail

I just got a new Nexus 7 32 GB, I did a factory reset on it and then tried to update to 4.2 but it fails during the installation, it shows a dead android with a red exclamation mark after about half the installation and then reboots in to 4.1.2 again . Anyone have any ideas? No roms or anything used just factory reset.

I may have bricked my Nexus 7 and lost my data. Any ideas appreciated

Hello, I fear I have bricked my nexus 7 (2012 wifi unrooted) and lost all of my data
What Happened?
Play store would crash on startup so I went to restart my tablet.
When turning my tablet back on it gets stuck on the four circles loading screen and does not load any further.
What Have I Tried?
Firstly I went into recovery mode and tried "wipe cache partition" as recommended elsewhere. This changed nothing
Then I tried to flash 4.4.3 on in hopes it would replace potential corrupt files (whilst also getting an early update )
I used this guide cultofandroid com/63876/install-android-4-4-3-nexus-5-nexus-4-nexus-7/
It failed. When running flash-all.bat (with -w removed) it would be stuck on "waiting for device" and my tablet would also be idley waiting to receive files.
I thought that my laptop could not 'see' my tablet but think it actually could because I tried restarting my tablet whilst it was plugged in still, and command prompt showed some messages (unfortunately I didn't take note and cannot remember what they said!) whilst it was restarting
State of tablet now
I now cannot even get into recovery mode
When I turn my tablet on the normal way it loads to a screen which shows the "Google" text in the center of the screen, an unlocked padlock at the bottom, and the fastboot options top right (clicking them does nothing)
When I turn on my tablet on into fastboot mode and try to get into reovery mode I get an error message in the top left of the screen saying "Booting failed"
I'm out of ideas.
Is there any way that I can get my tablet back working normally with all my data safe?
Thanks for any and all help/suggestions
Don't go into recovery mode, just leave it in fastboot mode and run the flash-all.bat.
(The -w might be needed, as it reformats your partitions. Yes, all your data goes but if there are faulty sectors, this is the only way)
Thanks, I left out the -w but it completely wiped the tablet anyway. Better than having a brick.
Before I assumed you couldn't flash with out getting into recovery.
For anyone else doing this be patient. The command prompt looks like it has stopped a couple of times but it hasn't. Its only finished when it says 'press any key to exit' (took 4-5 minutes for me).
Also when it reboots your tablet it takes a while and actually reboot mine 2-3 times before it loaded up.

[Q] Nexus 7(2012) stuck in fast boot mode, bricked?

Have a standard Nexus 7(2012), 18m old. OTA upped to Android 4.4.4. a month+ ago. Never rooted. From then on it has lasted a week or less before freezes/reboots while using apps or even nothing at all.
Have undertaken boots to fastboot mode (android on its back, door open but no red triangle) and then entered recovery mode to wipe system cache and then do a factory reset. This sometimes progresses thru startup restoring apps ok. Sometimes it crashes part way thru. Often get background Chrome and Maps crashes of late as it redownloads my old apps.
Google HW support line recommended this course of action until last time when desperate Indian woman out of her depth tried to say it was a hardware fault and palmed me off on Ausus(uk) saying they did a 2yr warranty... which I think they don't. Still to investigate that one.
The reboots kicked off again today. So did the usual: did a cache clear then factory reset and it restarted. Now it crashed while the Android coloured balls still rotating! And forcing into fast mode to do a 2nd factory reset failed as when I select Recovery Mode it now says "Booting failed" in small letters at the top and dumps u back in Recovery mode, though less the Android logo on its back. Cannot restart bootloader either, same error. Rebooting just freezes with "Google" displayed.
Have I "bricked it" somehow. How to I get past this?
As a novice, I have got Nexus Root Toolkit v1.8.5and tried to reflash to stock 4.4.4 rom on it. But bootloader is locked, as it is delivered, and it will not unlock it. (read from The Definitive Guide on How to Restore Your Nexus 7 Tablet (Even if You've Bricked It from nexus7 wonderhowto site)
Anyone got any info on what to do here? Better reflash tool/instructions? Is it hardware problem? Do Asus uk do a 2yr warranty that I need after 18months? Is this tablet permanently a dead parrot?
Any help, I am desperate here. Thanks

Restart problem Nougat 7.0 on security update - fully stock

I downloaded the 2016-11 update - hit restart and install and as it starts to boot I get the green android robot on his back, red triangle and an exclamation mark - it also says "no Command" further down the screen - it then starts as normal after about 1 minute - Please help what can I do? I had spent a day reinstalling and configuring this repaired phone. The hardware repair is otherwise fine.

After Logo black screen, no root, stock rom 4.4.2

Hallo,
i hope someone can help me here.
After a low battery my phone doesnt turn on any more. After some research i thought it might by the "death battery problem". So i but the phone on Laptop Charge port for 6 hours and i got it booted in to system.
But only for some seconds and it turned of again. So i decided to buy a new battery. Installed it and tried to boot. Sometimes it bootet in to System, sometime just got Blackscreen. I tried hard reset in it showed some errors. That was some days ago. Now it boots and everytime blackscreen. I tried also longer presses like 10 secs and 60secs. I tried fast press for hard reset with boot logo. I have no detection on Windows. I never rooted the phone and it has still stock rom. Must be the latest kitkat 4.4.2 i guess. I checked every cable. No charge led or logo.
Hey dude check out my video https://youtu.be/rpmbk9RFE_U there is step by step instruction how to reflash your rom... Just watch im here for any questions.
