[Q] OTA update to 4.2.2 problems

My 7 is unlocked and rooted, using Nexus Root Toolkit. I did an OTA to get to 4.2.1 some time ago and that went well. Root and unlock persisted. I am now getting OTA options for 4.2.2 from the System menu. First time I got and error in Android's belly. I restarted and was still in 4.2.1. System then said that I was up to date. A week or so later System told me again that OTA was available and I got the same result.
Any suggestions as to how I can do the update?

You have two choices
1. Flash the stock 4.2.2 image using fastboot from here https://developers.google.com/android/nexus/images
Or
2. Flash this in CWM recovery (note this link is for the wifi model) http://android.clients.google.com/p....signed-nakasi-JDQ39-from-JOP40D.6ece895e.zip

You have to restore everything except relocking bootloader ... To be able to update ...when u finish ..just re-root

Same thing happened to me, I had to unroot and then root again after update.

Thanks for your post. I tried this using Clockwork and got a very long error message. I will quote part of it.
assert failed_apply_patch_check("/system/bin/debuggerd", "a2323a0c8 and a lot more
This is followed by error in file
I saw something about busybox changing some system files.
Any ideas??

How do I unroot without whipping all data?

Search this forum for "OTA debugged"
There are only a few threads - read them all before you take any action.
This particular problem appears to be caused by StickMount.
You don't need to delete everything, nor do you need to flash the ENTIRE stock image - only the boot.img and system.img (via fastboot) without doing a factory reset or any other wiping.
This will unroot the ROM, and (of course) prevent StickMount from working. So you should over flash a SuperSU root kit afterwards (via custom recovery).
This very same problem may recur on the next OTA - so for goodness sake's, make a nandroid backup before you re-install StickMount and give it root privileges.

Sorry for being a numpty... can someone put the above into a mini step by step guide for me.. I'm stuggling with the terminology.
I rooted my Nexus and have since forgotten anything techie regarding it. I have StickMount and cannot update to 4.2.2..
How do i flash boot.img and system.img via fastboot, where do i get these files from, what versions etc do i need? And over flash SuperSU root kit?
What is OTA?
Basically, I think i need a newbie guide. I am techie enough to achieve most things normally.. i just don't know the android system at all, and what i did know to be able to root it i have completely forgotten!
Any guidance would be very much appreciated. Cheers.

If you want it that bad. Just download the factory image from Google devs and flash it.
Then you also have stock ROM running.

Is there any way to revert back to stock recovery in order to get the update?
Further more, is there an option to do so without re-flashing stock all together?

You can get the stock 4.2.2 recovery from the 4.2.2 factory image. I did have it but as I only keep the current factory image I only have the 4.3 recovery to hand

OK, did some further investigations and here are my findings
1. If you have it, you can use Wugfresh's toolkit (V1.6.4 for now) and it has a utility that can simply restore stock recovery and if you want it, stock kernel as well.
2. The Toolkit will download all necessary files and prompted you before each step.
3. It will revert back permissions for the stock recovery as well
I'll give it a try later on at home.
Thanks guys

I am a bit confused. According to the “Nexus OTA Help-Desk” thread, the way to do this is as follows:
Scenario #2
You are stock, with root. Custom Recovery without any modifications or deletions.
Continue to Section B
Section B: Flashing in a custom recovery
1) Download the OTA.zip and copy to your phone.
2) Boot into recovery
3) Flash the OTA
4) Flash Su.zip: (SU is being updated often so check Chainfire's G+ for the latest) https://plus.google.com/+Chainfire/posts
NOTE: Root on 4.3 is not stable. Your mileage may vary.
5) Reboot
So, what is different about using this method to install the OTA and just running the OTA from the notification, and is this the incorrect method?
Is returning to the stock recovery the preferred and more or less foolproof method?

I'm not sure why there's people saying otherwise, but from my experience you don't need stock recovery to take on an OTA...
I've updated my N7 several times now from when I first bought it to 4.3 currently, all the time with a custom recovery. Unless you've changed some other files which causes an error during the OTA update, I don't believe there is a need to re-flash stock recovery at all.

@mlj11, lots of people have the OTA failing on them, even if they are on rooted factory image 4.2.2.
Why the OTA fails on rooted 4.2.2 is still unclear.
My N4 with rooted factory image 4.2.2 also updated like it should without error.
Maybe the unlocked bootloader is the issue letting the 4.3 OTA fail.

@DecypherT
I'm not saying that rooted users will have no problems updating. My post was in response to people on this thread saying that a custom recovery will stop the OTA. This is false.
It can't be the unlocked bootloader (and it has never been) causing the problem otherwise you or I wouldn't have been able to take the OTA, for example. More likely it's something else.
If any of a user's system files have been altered, there's a good chance the OTA will fail. In the past that happened to me because the Stickmount app changed one of the system files. Once I replaced it though, I could update without any problems.

Ok, good points you're proving here.
Still, it looks like the (OTA) android 4.3 is very unstable.
I'm on rooted 4.3 and experience no big bugs or flaws though.
I do see a very large decrease of battery life when using the phone (screen on) and a big increase when in deep sleep. When the phone is off I almost use no battery.

OK I tried that but I got a Status 7 error message and it aborted install. I have everything stock that I can think of. No custom kernel. No nothing. Any suggestions other than flashing back to stock completely via Wug's toolkit then doing the OTA through the tablet itself and then restoring everything with Titanium Backup?

You don't need to flash the stock image and lose your data, but even if you are on stock 4.3 you still need two things: stock recovery (if you don't already have it installed) AND you need to unroot! Being rooted will throw the Status 7 error.
Here's what I did:
First flash the stock recovery for JWR66V in fastboot.
Then use the "Full unroot" option inside SuperSU.
Apply the JWR66Y update using ADB sideload.
Then reinstall TWRP and install UPDATE-SuperSU-v1.51.zip using TWRP.
After rebooting you may be surprised to see that the SuperSU app needs to be installed again (seems to be a quirk a lot of us are having). Just head over to Google play and after that all should be good.

Hi, I'm looking forward to doing this step since I really want to get that OTA installed in my device. Mine is on stock ROM, rooted via wugfresh toolkit. My concern is, after doing this step, will I lose all data? Also could you please explain how to do the first step- "First flash the stock recovery for JWR66V in fastboot."? I'm still a bit new to all these things, so please bare with me.
Thanks!

Check out this thread. I flashed the Grouper.zip file, which is the OTA modified by commenting out the validation check that results in the Status 7 error. I copied it to /sdcard along with the Supersu 1.51 zip. The ota flashed perfectly using TWRP recovery. After booting and going back into TWRP, I flashed the supersu1.51 and regained root. You do not need to unroot or flash stock recovery to get this update. No data loss. I'm stock rom & kernel, rooted with TWRP recovery.

You won't lose data if you repeat the steps I took. However since you are asking how to flash a recovery in fastboot I would seriously be careful and do a bit of homework on how fastboot works. All the instructions you'll ever need can be found by searching xda. It really isn't as daunting as it sounds but you definitely need to understand how it works before trying it.
Or you could try the link that Groid posted if you aren't concerned about skipping the validation check. The process is definitely is simpler if you're "new to all these things".
I'm not opposed to using WugFresh's toolkit, he's a brilliant developer, but it's never a bad idea to learn about what happens in the background and see it with your own eyes.

[Q] Nexus 7 Jellybean 4.3 update

hi,
apologies if this has been asked before but my searches have not found a clear answer. i have a 2012 nexus 7 Rooted and running JB 4.2.2.
the OTA update to JB 4.3 fails everytime. it gets so far and then shows the android logo with a red triangle exclamation and just "error"
it reboots back to home screen after a minute or two.
my device was rooted using WUGS toolkit and TWRP recovery. i just did the basic rooting so i could use stickmount and have done nothing funny with the device since.
i have seen many guides about flashing 4.3 update that will wipe the device which i really want to avoid.
will it work if i just un-root and re-lock the device with the toolkit and then run the OTA update or is it more complicated than that.

Same Here!, I had TWRP recovery and I'm rooted, so Just Flashed stock recovery and I though I can update easily. But now I can't!
-By the way, I did not change any system file.

Since you have Stickmount did your error message reference a bad file check on 'debuggerd' in the /system/bin folder? It seems Stickmount may replace or alter that file and you have to put back an original for 4.2.2 to successfully flash the update with TWRP. After replacing 'debuggerd', the update flashed just fine for me. Are you sure you didn't get any text other than 'Error'? Are you sure you didn't freeze or delete any system apps?

It also happened to my nexus 4, they recommended to use this way: (It won't erase the data)
http://forum.xda-developers.com/showthread.php?t=2377307

hey, the error has no message or info. it literally says the word "error" with red exclamation and thats it. i have not touched any of the system apps or done anything that could upset the system files.
i will try the suggestion from alipashang77, thanks

There's tonnes of older posts with all the info you'll need. Gotta just search more.
Ota will erase everything except your internal/external sd cards. Plus ota wont work if anything system wise had been altered. You'd have to Odin stock 4.2.2 then do ota.
No reason why you can't just flash a 4.3 rom like anything else tho.
And in all cases, wiping your data and apps is best. You gotta back it up. Restore after. Apps and their data anyway. Restoring system app data is never ever a good idea.

Device won't update via OTA with a custom recovery. And 4.3 OTA will fail if you're rooted. So in order to get OTA make sure you have stock recovery and unroot, then as long as you haven't modified anything system wise it should update successfully. And no, OTA updates will not wipe any data.

thanks everyone. its finally updated to 4.3. i backed up my data and then flashed the stock 4.3 image and that failed and the device would not boot. i thought it was bricked but it let me flash the 4.2.2. image and then the 4.3 OTA update worked.
:good::good::good::good::good:

hi guys i know that the previous reply was that flashing to the 4.2.2 worked then the OTA worked, however i have an explaination for people that were stuck like me
i JUST managed to upgrade my nexus 7 to 4.3 (JWR66Y)
i found a helpful link to upgrade from http://forum.xda-developers.com/showpost.php?p=34552123&postcount=1
after following all the steps, my i wasnt able to flash the bootloader (bootloader-grouper-4.23.img).
after doing some googling today, i found that it is the bootloader in the 4.3 update that is different (according to http://forum.xda-developers.com/showthread.php?t=2417097&page=2) and that you need the JWR66V bootloader img file (which is also the bootloader-grouper-4.23.img) they explain it in the link above, and have a download link for it there.
so in order to do the update, what you need to do is follow the steps from the 1st link (extract all the files etc in place), but before flashing, copy the bootloader from the 2nd link into your platform-tools folder, then follow the steps to flash.
as long as you follow the steps, and skip step 10, you will keep your data also
hope that helped

Past OTAs would be successful when rooted, you would usually just lose root access. But the 4.3 OTA won't work while rooted, you'll just keep getting the failed message.

Nexus 7 2013 Android Update 4.3 to 4.4.2

Do you have problems updating Nexus 7 from Jelly Bean to Kitkat? Well I did, since the day got my hands of N7 device, it was unlocked and rooted.
Somewhere is Sep the News of Kitkat has been rolling out. In Oct my N7 device notified on the new Kit Kat upgrade. I have been trying using OTA update but each time came to "FAILED" installation and so decided to give up the idea since JB 4.3 was working fine.
Now Kit Kat rolled out 4.4.2 version and still I had the same problem, did some researched on XDA forum and tried each of their suggestion but still did not work out. I was always stuck with "KoreanIME.apk" error on recovery, perhaps something I deleted earlier on.
Using Nexus Root Toolkit Ver 1.8
Finally decided to use the Nexus Root Toolkit (NRT). The last time used it was rooting the brand new N7. Run NRT and it started gathered information and upgraded to latest NRT ver 1.8.
With the new NRT version I decided to Flash Stock + Unroot, hoping I can do the update by going back to stock. To my surprise NRT found the latest Kitkat 4.4.2 and installed on Nexus 7. Most of the data was lost but had earlier done a backup. After which just like a brand new device, log in my account and immediately all the previous Apps started to download back to the device.
Once that was done, Root the device using NRT included Custom Recovery check, the rest just follow NRT instructions to install BusyBox and all is Done!!
Apps like Watsapp had to be installed manually since it does not support tablet version. Other data were also done manually.
I would not recommend this method unless you are prepared to wipe everything clean, so do a backup first. There were no other options and this was the only method.
Hope this helps and if anyone can point out the mistake I have done, do share for others.

OTA update doesn't work with custom recovery if I'm not mistaken

OTA can work with custom recovery, I've done it several times, though the custom recovery was overwritten by the update.
Sent from my SGH-I747M using xda app-developers app

Yes, OTA in the form of .zip file can be flashed via custom recovery.
But it seems that OP's problem occurs when he's trying to update from official OTA notification, from my understanding if you try to update from official OTA notification with custom recovery installed it will fail.
Please correct me if I'm wrong since mine was done through adb sideload

I did it through the official OTA (not a zip file) with a custom recovery. There seems to be a myth out there that it's not possible, but I can say from experience that it is possible.

Just for clarification, besides using auto OTA update, I did tried it manually using razor and SuperSu zip files. Also as you mentioned ADB sideload. It did not work out.
Somehow using NRT was much easier, just sit back and let NRT do all the job. The only setback were the missing data. Not a big issue, anyway was nice to see the file structure cleaned up.
