[Q] nexus 7 keeps restarting after 4.3 update

this is my first time making an account/posting on xda after being a long time reader and user. just need some help with my nexus 7 32gb WiFi (Australian model) i have loved this tablet and I have never had a problem with it, its unrooted and has never been dropped or anything like that, i updated it to 4.3 ota last night and almost instantly after that I have noticed it keeps rebooting itself like so many other people have problems with on earlyr versions like 4.2, please tell me what I can do to fix this, I can't find any straight help, my location is off and always has been, but I have noticed every now and again I would notice (on earlyr version) fused location would always stop working and ask me to force close randomly, that now doesn't happen but instead it retstarts, so do u think this could be the problem? any help would be awesome, thanks.

If you're having a problem with 4.3 you can try two things.
1. Revert back to 4.2.2
2. Try a rooted official stock ROM.

I fixed the proble,m, I found a site that finally gave me a good option to try besides rooting as I don't want to root my nexus 7, turns out HD widgets was cashing the issue, but the issue only showed up after this update, thanks for ur help though.

I've had random reboots on 4.2.2 and one since updating to 4.3. Usually happens when I am mounting or unmounting a USB drive, but sometimes it's for no apparent reason.

Anybody want to try a possible fix or mitigation for random reboots?

UPDATE: don't need anyone testing this anymore as it is not fixing most reboots
Can someone who is running custom recovery and has bad/frequent reboots install the attached file and see if it alleviates your reboots?
Please let me know what version of the OS you are running and if you are on JSS15J or JSS15Q, whether you updated via factory image or OTA.
I am 99.99% sure nothing bad will happen to your system. This will not disable your ability to get OTAs, nor change any system files, nor affect touchscreen, nor affect GPS, ...

I'm running a version of cm which has worked better than stock but still a daily reboot. What is this file going to alter / Will it work on cm?

If it works, it should work ok with CM as long as you run it in TWRP.
It doesn't actually touch the ROM. It uses the kernel to reset the DDR3 memory timings and allows the system to retrain.

Thanks, I like to know what I'm flashing. Just flashed, will report back.

I'm on 15Q odex stock ROM. I never had an ota before.
I rooted and unlocked the boot loader and flash this ROM yesterday.

Just had a reboot on mine as well.
Running build 8 of this:
http://forum.xda-developers.com/showthread.php?t=2391779
[ROM][CM10.2][4.3][CyanogenMod FLO Kangs][DJL10.2][LINARO][Build 8][2013/08/25]

Ok, then it looks like this won't fix the random reboots.
Sorry, back to your regularly schedule program.

im on clean rom with elemental x 1.2 and i have never had a reboot or anything bad happen since. i did have issues on stock 4.3 with small tweaks but since clean rom i have had no issues whatsoever
Edit also was on slim bean flo and had same issues so it's something messed up in the rom i would assume and not the software version it self

Many problems with 4.4.2 on Nexus 4

Hey guys, I've been having A LOT of issues with the new updates. First the 4.4 and then the 4.4.2 that didn't solve a thing. I've installed them via OTA but after that i've already did:
- factory reset
- installed via fastboot 4.3, then updated via OTA to 4.4.2
- installed via fastboot 4.4, then updated via OTA to 4.4.2
- factory reset AGAIN - installed via fastboot 4.4.2.
I don't know what do to anymore! I can't take pictures because nexus just turns off the moment i take one. I can't install facebook, twitter or instagram and another random apps... And btw, is it normal that in 10 minutes the battery charges to 1% to 50%? i think i never noticed that...
BUT WHAT DO I DO? PLEASE HELP!
UPDATE:
This problem is solved, it was the battery. I've changed the screen recently and it needed a new battery too. Thanks to everyone that tried to help me

If you don't know how to use fastboot, use the Wugfresh toolkit, makes life very easy. It has the drivers, downloads recoveries, root files and the factory images. Really is easy with that.

Guys, like I said I used fastboot to install 4.4.2, it still didn't work. I followed this guide googlenexusforum.com/forum/nexus-4-roms/4046-guide-flash-stock-option-using-android-sdk-tools.html

Hey, guys, I haven't updated it to 4.4.2 yet cause my phone is rooted so I'm asking is it worth to go through all the process again? And if yes can anyone state the new features? ☺ thx a lot!

Looks like a hardware issue to me. Probably your battery is faulty... Could explain the shut downs and trying to use the camera usually drains more battery so again that could it be. Could you be more specific about the other errors that you get?

Hardware? It started to happen only when I updated the first time via OTA to 4.4.
I open the camera, I try to take a picture, the flash goes on and then the phone goes off. Sometimes I can turn it on and the battery it's the same, sometimes I can't turn it on without connecting to the charger because it goes off when I go to insert the PIN.
Well, after I understood that the problem was that apps, when I turned the WI-FI on, the phone immediately turned off after that I unistalled that apps and when I turned the WI-FI on I could go on Chrome and Play Store, and installed some apps (like n7 player) and everything was OK.
One time I installed Twitter and I used it for a bit and everything seemed fine but then I installed Facebook and the phone crashed again so I unistalled both. Same with Instagram.
I don't know how much more specific I can be... I really need help :s

it's not hardware. anyone who had this phone running pre 4.3 aosp will remember the camera issues and the clicking noises that went along with the focusing and then the reboots. the battery charging is also a widely experienced issue as well as going from a full charge to 50% in a few minutes. I'm getting the camera bug again on 4.4.2 hope a .3 build pops up soon to deal with it. I'm also 100% stock no root

exactly this is happening but on 4.4.2
BTW, when I'm charging the phone, none of this problems happens. I can install and use all apps and use the camera.

if I were having all those issues I'd try installing the Factory Image again or maybe try 4.4.1 and then use the OTA to update. BUT there is definitely some bugs in the latest KK release

I did all of that as I refered in the beggining... I will try to install 4.4.1 though, that was the only thing I didn't do, but I doubt it's gonna work, because installing 4.4 and 4.4.2 didn't solve a thing

sorry about the double post but there isn't the factory image for 4.4.1 here... https://developers.google.com/android/nexus/images#occamkot49h .
I tried to flash 4.4.2 following this guide http://rirozizo.blogspot.pt/2013/11/guide-how-to-flash-factory-images-from.html and when I turned it on I had no signal.. what does that mean? I guess it didn't worked..

The latest factory images are 4.4.2, that's why you didn't see 4.4.1 on Google's server. When you flash factory images, your radio will also be updated. When you flash a custom ROM, your radio doesn't get updated, that's why you had problem with cell signal. Or flash the appropriate radio for the ROM.

The phone asked me to insert PIN and then I had cell signal again.. Should I flash 4.4.2 again flashing the radio too? Because I have the feeling that this will not solve my problem. Like I said in the beggining I followed another guide to flash my phone, and in that guide it said to flash radio and "bootloader-mako..." (not sure what that is) and the cell signal problem still happened and then I couldnt install Facebook or Twitter or had my location on or using the camera without the phone turning off or rebooting...
EDIT: The phone just turned off when updating Google apps, so yeah... Didn't work :s

You said that when a PIN is input, the phone has signal again which means it's not a radio issue. Did you set up a PIN in the security section in your phone?

No this is just something that started to happen along with the other problems... Sometimes the phone loses signal for no reason and goes to the PIN input screen.

Which radio are you using? It should be .98 if you are on KitKat 4.4.2. You can flash a standalone radio zip file in recovery.

I don't know I will check later because now I'm not home. But when can I find that zip file and if I flash that it will only solve the cell signal thing right?

Samsung keyboard on stock kitkat not working?

If I flash stock kitkat my Samsung keyboard won't work (force closes over and over).. I've no problems with any custom roms, on sweetrom now with no problem.. It's not a massive issue but it's annoying me! Does anyone have any suggestions as to how to fix it?
P. S- installing SwiftKey etc isn't fixing it..

You may need to do a full wipe when you flash stock, it's possible something has corrupted somewhere along the line.

Yeah I've tried all the usual tricks, re - downloaded stock from several places with no luck.. It's baffling me..

Format all your data in system via CWM - then reinstall your ROM from scratch, it'll fix any coruption issues. ->>> Important >>> Make sure you make/get a PIT file for your device before you change anything in case you need to sort your partitions out for a reflash

I'll give it a try thank_you...

Nope still got the same problem.. Must be some weird conflict with my phone that I can't pin down.. Like I say I'm on a custom rom anyway but it irritates me because I know it's still there...

How bizarre , I'd stick with the custom ROM for now just in case something else gets crazy corrupted - This Kitkat stuff atm is causing havoc all around.

Yeah I think you're right, maybe different batches of phones and buggy kitkat are causing problems for a few of us? It'll all get ironed out in the end hopefully..

I got the same problem. KitKat update failed in the end and had to CF_Root in order to boot up.
Action Memo (with pen) are not working for me as well. It is all linked with Handwiting somehow.
Is your Action Memo broken also ?
The only thing that I didn't do is Wipe Data/Factory Reset in Recovery mode.
Did you try that ?

got the same problem as yours, no idea why though, after the update samsung keyboard and action memo stopped working.
I think I will wipe it tomorrow but it seems it's not working either

I'm checking around and they say that problem probably lies in the application S Pen Keep, there is no data on this one ... I guess as you said it's linked to the handwriting recognition. tried to do that using Snote transform into text as well and it immediately stopped working as well..

For time being I'm using different keyboard and I like it better than stock one. I really don't want to wipe a phone. Takes so much time to install everything back.

Did u guys intentionally or unintentionally uninstalled Samsung apps? From what I've understand, certain Samsung apps needs to be either freeze thru TB or disable it...

Haven't touched it. I've upgraded to KitKat without updating a bootloader and it happened.
Sent from my SM-N9005 using Tapatalk

same here, got the OTA update, after that it simply stopped working.. I don't need the keyboard .. I need the action memo more

Mine still isn't working, I'm on omega rom now so it doesn't affect me, but it still does it if I flash stock... Strange..

try to download another stock rom? maybe that will fix it.. if it did .. let us know... try to download the newest one that came up in Poland..

mine got fixed by formatting and wiping, re-download another stock rom I guess yours has some form of data missing ..
@Colide , just go back to factory settings , will resolve the issue, do it from the recovery of course.

I kinda hate it to wipe data. Lot of apps to reinstall. Thanks for a tip. ?

Sm-9005 power problems

The phone turns off randomly and i'm unable to turn it back on unless i'll take out the battery for a moment or connect it to a charger.
When using the charger method, the phone will display the empty battery animation but turns on when i hold the power button.
I can't point a specific scenario that cause the shut down, however, it seems like the phone uses more power than the battery can provide.
For example:
Happens in various battery percentage.
Happens more frequently when using navigation or Bluetooth.
Happened with stock kit kat rom.
Happened with cm12 (philz touch 6 recovery).

Sounds like a defect battery to me. Is there a bulge or bubbles on it?

at my 9005 work fine
CivZ-KK_Xplorer-Rev1.9-sm_n9005-4.4.2
it's very good
but i dont like cm 12

I want to try to replace the kernel, but since i'm using cm12 (5.0.2 lollipop) i can't determine by myself which one to install.
The n9005 kernels page here on xda show only kernel with kit-kat versions in the title or no info at all.
Ultimate kernel page for example doesn't say if it will work.
Olso, do i need to touch the rom or i can just install the kernel from the recovery and then reboot into my already installed cm12 rom.
Thanks for the advices.
