[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.

Root and ota update

Hello guys I'm sorry it's really noop question
I have note3 n900 with Kitkat 4.4.2,
Is there a way to root it and still capable to get update by wifi? I know when the system been rooted will be modified and never receive update by wifi
I hope there's a way now.
Regards [emoji4]

Still no workaround.
You have to update via Odin.

Damn it ?
Thank you bro for your response

I download zip file from sammobile/firmwares , flash via Chainfire's MobileOdinPro. (its only a £$¥ and he deserves every cent) enable everroot, have all necessary files on external sd ie custom recovery ( CWM,TWRP,PhilsTouch) backup of last usable system, kernel and data.
towelroot.

Don't think so.
That solution is just for keeping root while flashing an update.

[Q] OTA 5.0 and Root

I just received the notice about the OTA update for android 5.0, if I install it will I keep custom recovery and able to install SuperSU for root access or do I lose complete root access and custom recovery?

If you have enabled ota survival in supersu you won't lose root (not 100% sure). Custom recovery will stay as is.

I think ota will fail quite surely as this time the script looks whether the complete system partition was tampered with which you have done by rooting
So either you first flash a fresh stock system.img or, which would be quicker and what i have done, do a fresh flash with lollipop factory img

The KK-to-L OTA update for Nexus 4 works the old way - by validating signature for every file to patch.

Not true, it patches the entire system block directly so OTA will fail in the OP's case.

In attached file there is updater script from "LRX21T-from-KTU84P" OTA update. There you can see that it verifies files on system partiton.

Hmm strange..
How come all over the internet people tell you not to do 5.0 ota cause it checks the whole partition hash??
Well.. For me it's too late anyways xD and a fresh install feels really nice (sorry for OT )

Do you believe in everything what people tell you? It's always better to check by yourself.

Well.. If quite a few different sources say that the ota mechanism is different this time, i believe it, yes.
And manually downloading the ota wasn't really sensible to me as my internet speed is really slow.

Has it been confirmed possible to download & install the OTA successfully on a rooted device running 4.4.4?

Yes, but you have to unroot (use the clean-up function of SuperSU) and reflash stock recovery (use flashify and transfer recovery.img to your phone from the official 4.4.4 factory image from googles own download page). Also, uninstall all apps that modify your system files, like Xposed framework and mods, BetterBattery etc. I'm not sure if you have to re-lock your bootloader too - I don't think so, but i did it to be sure anyway.
I did all that, and applied the OTA without any problems when the update notification appeared on my phone. You loose no data, but you do loose root.

[ROOT] 23.0.1.A.0.167 [LOCKED BL] No recovery needed

Hello,
I just wanted to share how I have rooted my device today, and it was way easier than the methods I have been reading about so far.
My device: Xperia Z2 , C6543.
How I did it:
1- I updated my flashtool to the latest version, downloaded the 7.1.2.A.0.314 ftf for my region and flashed like instructed in the post. (Note that If you don't have flashtool installed, you have to go inside it's drivers folder and install the Z2 driver so it can communicate to the phone).
http://forum.xda-developers.com/showthread.php?t=2759934
2- After the downgrade to the 7.1.2.A.0.314 version mentioned above, I went to the flashtool menu (My 65XX -> Root -> Force towelroot)
When prompted to, I have choosen the SuperSU option.
Then the towelroot app showed in the phone's screen, I've tapped on "make it rain" and let it run.
After that the phone restarted and it was rooted.
3. Okay, now that the 7.1.2.A.0.314 is rooted, an OTA update notification showed up to update to the same version (lol). Well, I just let it update, and the root was there (I confirmed by restoring some data in titanium backup).
4. After that, another OTA update showed up to update to 23.0.1.A.0.167. Again, I let it download and install.
Well, that's what it took for me to root my z2 in it's latest version with only one downgrade and no manual adb commands, no manual rootkit downloads, pretty similar to the way I've always rooted my ZQ (R.I.P - it drowned lol).
The credits are due to the hard-working people who made all the mentioned tools, I am only doing my part by sharing an easier method than what i've seen around. Feel free to share your toughts.
Laters!

Sorry to be noob! Will it break anything like camera x reality or anything? And for warranty, can I claim it by just unrooting it(it's in the su) ?

Did not break anything for me. Now I can use foldermount and transfer heavy apps to the external sd. Wonderful. As for the warranty, since there is no recovery installed and no bootloader unlocked, it is as easy as doing the step 1 in the procedure described. It will flash the unrooted system back.

But ist same method, if u use this or this tool.

This post doesnt deserve an original development section!

thanks. I will follow this guide as i had root, upgraded and lost it. But i've have been itching to flash stuff lol.

I am not sure I understand what you mean, but if you are talking about the xperiarootkit compared to the "force towelroot" from flashtool, I checked the scripts in advance and they seem to be the same thing yes. The only shortcut to what I did was not having to flash recovery, and creating customized ftf, etc.

Did you tried ota survival in Supersu?

not before applying the OTA. Perhaps that would have helped. I have the app installed, but it says the binaries are not installed, to consult the forums for re-rooting

I think you have to do all the stuff one again and root device. Then check the option for its root survival and do ota updates. I think you'll be fine with the updates.

Question, /System RW? (don't confuse it with a TA Restore, as it could only be restoring to the /Data partition).

I doubt you'll have system RW access as sony ric should still be running, but if root is working fine flashing nut's recovery should fix this easily.

root achieved and kept
Nice one thanks for the info worked well and updated to .167 ota and kept root.

Going to give this a try. Thanks

Thanks for the info, OP.
I used flashtool to downgrade my D6503 to .55, tried to use towelroot, no luck. used the CVE root exploit and got root, but after that update center failed the verification to .314.
Your method works, so cheers!

Will the Phone be wiped during this root method

flashtool will wipe your phone unless you unselect data partition (not recommended). The rooting part is non-destructive so no that part won't your phone.

Tried to install nut's recovery with supersu option but all the apks in the script could not be written into system folder. Also could not install xposed installer. May have to downgrade again and avoid this method
update: no need to downgrade again. sony_ric prevents r/w to system folder even with root, so I just used ric killer by forty two: http://forum.xda-developers.com/xperia-z2/general/4-4-4-sony-ric-killer-t2953141
afterward I was able to install xposed installer via normal method.

Thank you for the tutorial. It worked fine for me.
What will happen if I do a factory reset via settings-menu? Will root be gone? Do I have to downgrade again or can I install SuperSU to get root back?

Well then you will be surprised to know that the people with root can update via OTA, it's just that they will loose their root privileges after updating.
The only requirement for the updates is that you need to be on the stock CyanogenMod recovery to take the benefit of the updates also you need to make sure that the apps or zips that you flashed might not have tempered with the core framework of the system as the update checks the signatures before updating and if they don't match installation fails.
As for the OP, make sure you flash the stock rom and that's it. You don't need to unroot in order to get the OTAs. But if have missed it you can always flash the update manually

I'd recommend to go and watch this thread on YU forums, it's not mine, but it's the first post that came on how to get the update manually.
But still in short all you need to do is :
1. Download the OTA's .img file from here : https://drive.google.com/file/d/0B5qkmXkPr5WyMy1FUm9rNGdZZ2c/view?usp=sharing
2. Download the stock CyanogenMod Recovery from ere : https://drive.google.com/folderview?id=0BwVitsnY-WxvRVNYcnhRM05vX2c&usp=sharing
3. Download Flashify from app store if u r sure that you r rooted.
4. Open Flashify >> select "Recovery Image" >> select "choose File" >> browse the Recovery .img file that you downloaded and flash it.
5. Open Custom recovery, go to "Update" browse and select your ota update .img file and flash it.
It'll take about a min to flash it and if all goes well, you will have the updated build and the proximity issue fixed !
