New OTA break root?

Just got a notification for OTA to 5.0.1. Anyone know if this will break root? And if it will install with CWM custom recovery?

I kiddy got it too, I'll wait for the zip file lol.
Ya think it is really better to install from the zip file?

I downloaded the OTA but can't find where is the ota file. Any idea where is it?

Android Central has the log change. It's bug fixes really.
Also, in this thread a user states that apparently only with the full 5.0.1 can you install it with CWM.
http://forum.xda-developers.com/shi...p-nvidia-shield-tablet-ota-android-5-t2982677
You will lose root and CWM after the reboot but those took about 3 minutes to get back .. easy peasy. I'm now at 5.0.1 on my shield with root and CWM.
Cheers.
Hello aegern,
deletes the full update all the data? can you give me the recovery and root attach files?
Thanks

So here's what I did:
Download the full OTA then reboot to CWM (assuming your rooted + recovery) and unmount system partition ( I believe all others were unmounted) and then delete system, data, cache partitions respectively. Then flash the OTA zip followed by latest supersu.
Just tested this method and I have a rooted 5.01 32GB LTE US model working flawlessly. Even managed to take out the top spot in Hwbot Prime for the Shield (woops to newb for links I see lol)

So, did it work for you? I've tried the file in both this link and the official update and get the same thing with both. I'm still on KK and I can't install either the 5.0 or the 5.01 updates. I get the same "this is an ardbeg" error with any update I try to flash, and I'm flashing the full files, not the incremental updates. In fact, I have two tablets (both lte) and I updated the first one to 5.0 a week ago, no problem, but the new one I just bought, I can't even though I'm using the same files (cwm and update). I'm stumped.
Bah. nm. I went back and reinstalled the recovery from here again, http://forum.xda-developers.com/shi.../recovery-cwm-recovery-nvidia-shield-t2848064. Flashed 5.01 just fine. Not sure where I got the other recovery.

Hi dgjenkins, sorry answer so late. So, answering you first, not, it did not work for me. I actually did give up, the bad was that I tried so many ways to do it that I freezed the tablet and did not start again. Well, looking out there, I found this amazing video who saved my tablet of bust it again the wall and start from the original firmware.
https://www.youtube.com/watch?v=GsMo1tPlIFU
I did intal the Minimal ADB and Fastboot
Copy the image files in to the Minimal ADB and Fasboot directory c:\Programs Files (x86)\Minimal ADB and Fastboot
Ope Minimal ADB and Fastboot
-Type: fastboot flash recovery recovery.img
-Type: fastboot flash boot boot.img

-Type: fastboot flash userdata userdata.img
-Type: fastboot flash staging blob
-Type: fastboot flash dtb tegra124-tn8-p1761-1270-a04-e-battery.dtb
And done . I can now install the updates from the stock firmware. Maybe I will root it again once a stable way to root the shield tablet appear out there. :cyclops:
Happy Holidays and Thanks for the interest! :good:
Nvidia updates definitely trump Android ones. These days, Google is in the habit of pretending that a nexus 5 camera bug is worthy of a new Android version (that was KitKat) or that an update is a great place to break functionality (App Ops, also with KitKat). Anything that's not a minor version with updates you know you want... Avoid on a non Nexus unless you have a great reason for it.
Manufacturers besides Google, see, they do this thing I like to call quality control. They generally release an OS that is ready for the hardware and software*. Crazy, right?

Installing 5.0.2 on rooted tablet

So I recieved the notification that the 5.0.2 update was ready to install on my tablet. My tablet is ROOTED but that is all, still stock, I only root to use ad away. I get an error trying to install it OTA. How can I install the update, without having to wipe all my data? Sorry, I am very new to this stuff

No go on root. Your system partition has to be pristine. (Technically you can add files, but the ones that came with it have to be unchanged) Just undo any changes you have made and unroot and the OTA should work.
So if I get this right, OTA breaks also when recovery is stock, but supersu installed, modified hosts and gps.conf file

The HOSTS file came with the stock image. It counts, unfortunately. (I'm also an Adaway user)
Modify /system, you don't OTA. Period.
Just download the Nexus image and flash just system.img, not the batch file.
Can I flash the system.img in TWRP or do I need to flash the stock recovery?
And will this upgrade me from 5.0.1 to 5.0.2 without losing anything except for root?
Thanks!

Thanks for the info. Just had this problem myself and was trying to figure out what to do. This must be a 5.x problem? I've never had this problem on 4.x as long as I had the stock recovery installed. Just had to re-root after. Guess I'm off to download the factory images since it won't even show an update available after erroring out. It definitely still shows 5.01 as being the version I'm on.

Just download Scrosler's Factory Stock Rooted Rom 5.0.2 in the Android Development section and install via TWRP over the top of 5.0.1. No need for a fresh install.

Oh I wasn't going to do a fresh install (i.e. wiping everything), just flash that system.img or modify the batch file to remove the "-w" flag and just run that. I'm wary of running 3rd party ROMs now after I couldn't play movies through Play Movies that were downloaded to the device instead of streamed. Something to do with copy protection I guess
It isn't a "3rd party ROM," just a flashable version of 5.0.2. If you flash using TWRP, just don't have it wipe anything. I flashed his 5.0.1 flashable ROM over 4.4.4 (after updating my bootloader) and didn't lose anything.

Assuming this was in reply to me? I'm not worried about losing anything. I've done the whole back it up and wipe between ROMs a ton on my OG Droid and Galaxy Nexus. In this case it's a worry that Play Movies for instance will detect that it is not a stock ROM/image and will disallow playing downloaded versions of movies in the app. I.e. you can download vs. stream for offline playback. I nearly found out the hard way (night before leaving on a vacation) that I couldn't play downloaded versions (it will download but not play them) when I for instance installed AOKP to my Nexus 7. As best I could tell from a bunch of Googling, it's something to do with copy protection.
It was, but I didn't know your experience level. I guess what I wanted to say is that scrosler's stock rooted ROM is exactly that; once it's on the tablet it isn't any different from rooting the OTA or factory image. It's just flashable via recovery instead of having to use fastboot or flash-all.bat.

Ah ok. Well, I ended up using fastboot to flash the system.img last night and looks like I'm good to go. I tried unrooting (SuperSU remove root function) and changing betterbatterystats to a non-system app first but the OTA still failed. Yeah I learned how to use the basic adb/fastboot stuff when I got my Galaxy Nexus and again with the N7. I figured that way if I totally broke something I'd know how to fix it, and all the fancy tools weren't around when the GNex first came out (at least I don't think they were).
I dirty flashed scrosler's 5.0.1 ROM when I got the 5.0.1 OTA notification, but when the 5.0.2 factory image was posted I fastboot flashed the system.img from that and rerooted. Naturally, less than half a day or so later, scrosler posted his 5.0.2.
So for someone that's not really too experience with fastboot, could someone post a step by step?
Where would I get the system.img?

thats because it was a brand new method for 6.0, it was just developed and bugs were being worked out
Everything's fine for me.
FYI, the radio.img and bootloader.img are the same as MMB29K, so they don't need to be flashed. Boot.img and cache.img are the same size, but I'll flash them anyway. System.img is a different size, so it definitely needs to be flashed.
Looks like the kernel is the same.

While this is true. These security updates are meant to target thing like the root exploits. So while things may still work don't be surprised if it does start needing updates each time Google pushes a security patch. It's a cat and mouse game that will be played until Google manages to lock it down to the point that it is not worth it to root.

Stock w/ systemless root and Elite kernel.
To applying the update I downloaded the factory image from https://developers.google.com/android/nexus/images untar and unzip image-shamu-mmb29s.zip to get at the system.img file. Then did fastboot flash system system.img, just finished booting and and 'upgrading' my apps. It looks like something in boot.img changed too, but everything seems to be running perfectly fine without flashing it; note that I do have a custom kernel installed, so that might have something to do with it.
If you also fastboot flash boot boot.img then you will likely need to go through the root process again to modify the boot.img to allow root to work properly.
Code:
$diff shamu-mmb29k shamu-mmb29s
Binary files shamu-mmb29k/boot.img and shamu-mmb29s/boot.img differ
...
Binary files shamu-mmb29k/recovery.img and shamu-mmb29s/recovery.img differ

Is there any way to ota update the 38.7mb instead of 899mb and do it without PC?

The latest April 2018 OTA update Google pushes to my Nexus 6P is only 38.7mb.
Since my phone is rooted, it won't work and I have to download the full factory image, while OTA image being 899mb and smaller than the full image, then TWRP sideload, then re-flash twrp and re-root with Magisk.
My question is, is there any way to download the 38.7mb (assuming it works) and sideload that instead?
Further, is there any way to do the adb and fastboot stuff without a PC (my PC is slow, even in Linux with all the latest update), maybe with another phone or tablet?
Another problem just came up, TWRP can't verify the 899mb OTA image and failed.
I downloaded and flashed the 899mb OTA file twice, both failed.
Anyone has the same problem?
Guess I have to download the full image and extract files and flash.

You can't OTA when your using custom recovery. However I've heard if people using flashfire but have never tried. With Google backup doing such a great back up now just clean wipe and start from scratch. We use too just use superXe was completely stock based and updated frequently but the developer is really busy .
While I've never tried this, and you could cause problems with your device (Make a full nandroid!), you could try flashing stock recovery from the full image, then flashing normally from within the OS.
After flash is successful, flash back to TWRP..

Most, if not all, rooted Nexus manual update tutorials tell us to flash recovery stock recovery image, then flash custom recovery.
But I don't see why, and I've almost always skip this step without any problem, since Nexus 4.
But you're definitely right about making a full nandroid part.

Problem flashing stock image

I have UB and rooted with magisk 20.1. I rooted the October build by patching the boot image using magisk. I try to flash the new November stock image and it fails. It says
Writing boot
Failed (failed to write to partition Not found)
I think it may be connected to booting into slot a or b. Maybe?
Can anybody help?

I'm on October trying to flash November
Pretty sure you cant flash the boot image alone. I always flash the stock boot for the build Im currently on then take the OTA. I think there is a new bootloader for November. Not 100% on that though.
I'm just trying to flash the full factory November stock image. I downloaded it, unzip it, plug in the phone in fastboot and double click the run me bat file.
This has always been fine before but I am new to pixel 3a and have only done this once before, on October build. But I came from an original pixel so I've spent 2 years updating that in this way.
I can't work out why the flash is failing.
Try flashing the stock October boot.img then try updating. Ive never been successful flashing an OTA or factory image over a patched boot.

I only ever flash the one in use.
Just fastboot flash boot boot.img is all you need.
Your can also always just clean flash the OTA. Just download it, factory reset, adb sideload the OTA in recovery.
I've done that a few times now.

Yes, OTA and factory images are essentially the same thing just packaged differently.
And the easiest way to reroot is to just download and repatch the new stock image, or flash a custom pre patched kernel.

The OTA zip is packaged differently and does not include a boot.img file that we can use. (I'm sure it must be in there somewhere, but not in a usable form). Therefore you must download the "Factory Image" from Google. Unzip it, open it where you will find another zip file inside. Open that second zip file and you will find the boot.img file there. Move that boot.img file to your phone so that Magisk can access it and to modify it.

FYI here are the steps I took to update my rooted 3a this morning:
1. in Magisk Manager select Uninstall and select restore images (I did this because I kept getting a 'installation error' on the OTA page)
2. Like an idiot I rebooted my phone, do not reboot! So I had to reinstall magisk
2a. copy the boot.img of Oct to my phone to have it patched by magisk
2b. fastboot flash boot boot_patched.img
3. the OTA downloaded while I was on the stock boot.img so I just followed the magisk instructions to install the OTA in the other partition
Next month I'll just jump from step 1 to 3 and carry on being rooted.
The simplest way to update when youre rooted is to......
Reflash the stock boot from the current build youre on
Take the OTA directly on the phone
Download stock image from new build and move it to phone
Patch with Magisk and move to your PC
Fastboot flash boot boot.img
Ive done this for the last 3 updates and it works perfectly every time......I obviously substitute my kernel for the patched boot but the process is the same. I find this far simpler than messing with Magisk
Thanks for all the suggestions but I still cannot update.
I have tried restoring boot.img
data reset from recovery
relocking bl - ota fails
Unlocking bl again - won't flash using ADB
There is no problem with the phone being recognised on ADB, the flash Just fails as the screen shot in my opening post. I'm thinking it may be connected to needing to flash to the inactive slot.
Anyone got any ideas?
