Nexus 7 OS got crashed - Nexus 7 Q&A, Help & Troubleshooting

Hi
While downloading and installing updates of apps my tablet stopped on its own and now it's showing only google word on screen and its not proceeding further to restart OS. Upon long pressing volume key android logo appearing with other info like
Fast boot mode, product name, variant, hw version, bootloader version, etc etc etc.
On the top its showing options like start, restart bootloader, recovery mode, power off. None of the options won't be able to restart my tablet. Can anyone help me as I am new to tablets and android.
Thanks

Are you 100% stock, stock/unlocked/rooted, unlocked/rooted/flashed custom ROM....?
Were you updating your apps via the Play Store and the tablet just rebooted, now it won't boot up?

Yes. I got notification that 4-5 updates available on play store and I selected update all 4-5. Couple of apps got updated and os shut down on its own

Problem got solved after manual factory reset using power n volume buttons. Looks like bootloader got corrected. Hence os is not able to restart. Thanks.

[Q] Rotation lock always enabled?

Hello, I have a N7 16gb C80 version running Stock rooted. My problem is I enable rotation and it works until i switch apps or press the Home button, then it locks it to portrait again. I have tried hard resetting, and even formatting system in TWRP and manually installing the 4.1.2 update, then rooting, and same. It was doing this on 4.1.1 as well, but only for about a day before the OTA came down.
Any help is appreciated, been working the google machine for a while to no avail.
No one else has experiences this?

Warning new supersu update lock the tablet

I just upgraded supersu from google play. After a reboot, the tablet locks after about 20 seconds or so. After that it is impossible to access anything. The tablet then reboot. The only pudate I did was supersu
It took me few tries to be able to access the settings and remove the update before the tablet locks.
Now it seems to work again without problem.
Don't update until the problem is solved
Mod if this should be placed in another forum feel free to move it

Same here, updated and did a few reboots due to enabling multiwindow in some apps and everything is working fine..
No problems here on note 10.1 and Note 2.
Just updated.. rebooted and no problems here..

Be worth reading Google Play comments before drawing any conclusions .

FWIW, I had the same issue, too. I'll also keep looking into it.
Also getting that request for "dumpstate", too.

I have looked further into the problem, it seems that the new supersu may not play well with some apps that request root access. I had avast anti theft software which required root. I uninstalled it reapplied supersu update and it is working. Also avast keep on giving me error even after the downgrade of supersu.
Like you I had the request for dumstate.
Finally I have avast on my galaxy nexus and the new supersu and no problem at all.
So as of now on the tablet I cannot have both (avast and new supersu) together

A friend of mine having the same issue with N7000.
How did you manage to uninstall update before getting stucked.
Same Issue here. Stucked after reboot after SU Binary update.
Managed to run "top" in adb shell which shows me that /system/xbin/su runs to many times......
no problem here on 5 devices

Restart the tablet as soon as you are on the lock screen tap status bar , tap settings, tap applications scroll to supersu and uninstall upday tap ok. You have to do it as fast as possible before 5he tablet locks... I had to do it a dozen times before succeeding
Good luck

This happened to me as well...had to race to SuperSU/settings and changed Default Access from Prompt to Grant and it stopped locking up...couple of reboots then and reset access on your apps after it completely reboots and settles down.....
I had this issue yesterday after installing ROM Android Revolution HD. I thought it was a problem with rom and returned to stock. But on stock I updated it and have no problems.
There's a new update with some bug fixes out. I don't know if it fixes your problem since I did not have it.

Nexus 4 big problems

I have some problems with my device, almost all applications are crashing: 'unfortunately the app stopped working' and sometimes it hot reboots by itself. The problem dissapers if i go in safe mode, i can download apps from play store, but when I reboot in normal mode and want to launch the app that I download it crashes again. I tried using the stock 4.3, 4 custom roms, different kernels, but the issue is still present, the phone is practically useless, I can only make phone calls on him..., everything else crashes. The problem is that I can't RMA ,because I bought the phone second hand.and doesn';t have warranty
and have you tried wiping data and running without any installed apps? then install one app at a time.. it sounds like it can be an issue with something that you installed.
Try downloading a stock rom, kernel, and IMG and flashing that. Sometimes stock fixes everything

Yes, I wiped everything in recovery ,even system too. After I log in in my google account everything starts to crash, gapps, UI, android keyboard etc. I tried making a new google account ,but nothing works, sometimes the play store works ,but I can;t download files larger than 4-5 mb, because at the end it says package file is invalid. In safe mode workes fine.
Sounds like you have the wrong gapps file. Or a corrupted one. Try a newer version.

How do I get rid of the system update notification on my Sprint G2?

Sent from my LG-LS980 using xda app-developers app
Well for me over on T-Mobile I either uninstall the update centre apk with titanium backup or flash a custom stock rom. But only problem is that say if something goes wrong example if you uninstall system keyboard and get forced to do a reset. On booting up you won't have the keyboard and might be in a jam especially when you need 1 to enter wifi password and mobile apn lol my t mobile g2 got an error and even tho I flashed back to stock the keyboard and a Lotta stuff I deleted are still not there and the phone senses it as an error and reboots after every 20 seconds upon booting okai good luck.

if you are able to flash roms then make sure you do a full wipe which is system/dalvik/cache/data. then install the rom. this should give you everything you have with stock including your keyboard.
Or you can just long press the notification go to app info and uncheck the show notification box

Wont download or update apps from the play store

I've had my G2 for a few months now, no problems. Earlier today i noticed that it wont update my apps or i cant download new ones. its just constantly stuck in the starting download stage, never actually starts downloading.
I've tried:
force closing the play store app
clearing the cache and data from the app
signing out of hangouts then back in (read that might help)
restarting phone, and powering off then back on
I am out of ideas. anyone have any suggestions?
I am having tg the same problem. Started earlier today. My guess is it's a problem with the market. Hopefully fixed soon.

ROM upgrade.
I have had this issue in the past and found updating the kernel from the custom rom's stock kernel to another kernel(furnace, paek, etc.) has worked for me.
I'm just on the stock LG rom, I've rooted, but that's all I've done. So not sure how to update the kernel.
Get a custom recovery like can or twrp, then look for a kernel compatible with your device
