Nexus 7 2012 unrooted - turns on but android won't load - Nexus 7 Q&A, Help & Troubleshooting

Hi all,
So yesterday I got the alert to update my nexus 7 (2012) unrooted tablet to 4.3.3 which I did. Unfortunately after downloading the update, when restarting to install, an error message came up with the android dude lying on his back and the word ERROR above him.
I restarted the tablet and everything worked fine apart from the fact that the tablet hadn't updated, which I could live with.
Earlier today I went to open the play store but it wouldn't load, the app just said no connection and there was a retry button. Wifi was working fine as I could play other games that need the internet, check twitter etc. So I decided to switch my tablet off and on again.
After turning on, the nexus animation logo comes up (with the 4 colours) and the tablet gets stuck on this page - it won't progress further and actually load android - I've no idea why this is happening. I haven't attempted to root the tablet or anything previously, only ever carried out OTA updates.
Any idea on what I can do please?
Thanks

I don't suppose anyone has any idea's on how I can get my nexus up and running again despite it getting stuck on the animation screen when I first turn it on?

The same happened to me. I had an error while installation of 4.4.3 . Since then, the device reboots, shows me the lock screen for 1-2 seconds and reboots, again and again. I tried the unbricking method with no success till now.

Thanks for the reply.
I managed to get my tablet working by using adb to unlock the bootloader and install the stock ROM again.
Then I locked the bootloader using adb and left it at that.
Only thing was the tablet factory reset itself in the process so I lost all my data etc. Id didn't have a backup which is my own fault I guess.

[Q] Nexus 7 troubles after rooting.

Hey everyone!
This is my very first " decent" post on xda even tho i do browse alot and read.
in ex when i rooted and changed roms to test out in my galaxy gio.. this place is truly a lifesaver and essence of everything what android is about.
now here is my deal.
recently ive ordered my usa imported nexus 7 from the swedish bazula.se
and was happy and everything. ive been reading alot about freezes and screenproblems, luckely i have not had those problems.. however,
yesterday ive decided to unlock and rood my n7 with the Nexus root toolkit v1.5.3.
installed the pda drivers and it all went well indeed without any problems.
exept now afterwards when everything went crazy.
after rooting, i couldnt open my f-secure mobile security app, no error msgs nothing,
also, as soon as started superuser app, it did quit after a second.
youtube videos are impossible to watch, it would stop the videos every 3 seconds. same with the games. freezes a second and meanwhile freazing, it brought up the game manu.. so impossible to play.
now, by that time it was really frustating and ive decided to install JB 4.1.2 that just got spitted out as a msg from the system that its avaiable.
root access was still there after the upgrade but in functionallity, no different, my problems did remained as above.
so i decided to do a factory reset. and problems still did remain.. so did the root. finally i did unroot the phone and reinstalled JRO03D and everything works again.. so does anyone of ya any idea wtf was going on? what could be the problem?
now should i try to update again to 4.1.2 without root?
thnks in advance

[Q] Nexus 10 stuck - read only? I can't update or change anything.

Hey guys,
I'm experiencing a weird problem with a Nexus 10 that was gifted to me. For some reason the Nexus 10 can't receive any updates and reverts to it's last state after a reboot. That probably doesn't make sense so here's an example:
I turn on the Nexus 10. I change the language in the settings. I connect to wireless. I install apps. When I reboot the nexus 10 has no history these changes were made.
Wiping/factory reset from Recovery does nothing. I can select the option but when I turn the tablet back on there is still a completely configured profile with personal data present.
It's currently stuck on 4.2.2. When I try to install the OTA update the installer downloads, the tablet reboots, then no record of the install is seen.
Finally, I've tried to flash Google factory images via ADB and fastboot. But, I can't complete the install because the bootloader doesn't remain unlocked after a reboot so the install never finishes. It seems to me the tablet memory is stuck in a state of read-only.
It seems to me the tablet is stuck on Read-Only somehow... does anyone know what else I can do? I've never experienced this problem before. Most of my research indicates an eMMC problem?
Thanks!

nexus 4 stuck at installing system update

my wife's nexus 4, is stock, not rooted.
she accepted the lollipop upgrade that came... and since then her phone is stuck at installing system update for past few hours.
I have tried to restart the phone by holding onto power button for a while... it restarts and then gets stuck back at installing system upgrade.
Any suggestions?

Have you taken the data backup? If so try factory data reset. Also try downloading lollipop factory images and install.
Ok.. after few more restarts. . Going to the recovery menu and more restarts. .. the system once went ahead into boot animation... and then update worked from there on.
Not sure why it did not work before or why it worked after 10+ restarts. But my wife was so glad that she did not have to loose all pics and whatsapp messages.
Thanks for ur suggestion thought.

Nexus 4 lollipop OTA fail [Solved]

Hi,
I recently tried to update my stock encyrpted Nexus 4 using the OTA Lollipop update. Now when I try to start the phone I can get past the decryption unlock screen as usual, but after that it gets perpetually stuck in the spinning circles sequence. Unfortunately, I have not backed up my data and would like to retrieve it if possible (I thought the backup to cloud feature was enabled, but I guess it wasn't...). I've tried pushing the official Lollipop update using adb sideload; everything seems to work fine (it unpacks and installs without any errors), but when I reboot the phone I still have the exact same problem as before.
Can anyone think of anything that I can do to recover my files? I'm holding out hope that my photos are still on the phone and can be recovered somehow.
Thanks!

[Q] Nexus 4 update not working

Hi Everyone
First post on this forum and first time trying to fool around with android.
I just replaced a new lcd + touch+ frame to an N4 its build was JOP40C
1) I said to myself why not trying to update manually to lollipop, well the N4 stayed stuck while booting with the colored dots.
2) I said to myself lets go back to JOP40c but that does not exist on google anymore so tried for hours many until JDQ39 and finally could get into my phone, but the number 6 and 7 where missing on the touch (???).
3) I said to myself well lets reinstall again and got totally my touch working.
4) Once done I received automatically an OTA from google, said to myself well lets do google, well the same happened again the phone was kind in a bootloop with the colored X.
Any help would be appreciated on why I am not able to update this phone, do I miss something that I should know and not found over all what I have read over the internet.
I have spent at least 3 working days on this and now I have to go back, make a living and hope that a pro will help.
I assume you're flashing the factory image and then you get a bootloop? Go into the stock recovery after flashing and do a factory reset.

Tried that too lots of post over the internet about that but nothing keep getting blocked on the colored cross or bowls.
Tried also with Nexus Root Toolkit
Just received again the google update to 4.3 jelly beans on the N4 pressed restart and install then got the green robot and saying installing system update.
Then the phone got stuck in his bootloop and tird again the factory reset.
Still stays stuck in its bootloop.

You ever check all sensors work?
Maybe the same problems with this http://forum.xda-developers.com/nexus-4/help/issue-sensors-update-t2973047#post60470486
HI
I have checked with another N4, installed a software and checked the differences.
Well you are wright on this one the luminosity and proximity sensors are not showing any sign of life.
It is already past midnight here in France, so I will check tomorrow if I can do something on these sensors.
Will keep you posted if I can fix the sensors and do an update after that.
Hi
How stupid I am, after screen change connector sensor was not pluged in and since I had placed the plastic cover with the screws, could not see it anymore.
At least after have lost so much time, next time I will post a little earlier and at least tonight I will go bed less stupid than yesterday
Google just send the 4.3 upgrade and everything went smooth just no touch anymore so cannot use the phone.
ok installed lollipop but still the same no touch, but now I can install an update but not use the phone.
Anyone on that touch problem
