Nexus 7 3G - 4.2.1 OTA Update for Custom Recovery - Nexus 7 General

Ok, so there seems to be some issues with installing the recent 4.2.1 OTA update with custom recoveries (ie: CWM or TWRP). I ran into this issue myself, and I've seen many other posts with similar problems. I've found the solution and explained it in multiple threads, but due to the nature of the issue, I thought it deserved it's own thread to make sure everyone is aware of the problem and the workaround.
Details:
The 4.2.1 OTA update comes in two flavors - nakasi and nakasig. The former is for WiFi devices (8, 16, 32), and the latter is for 3G devices. In turn, they each have their own device types - grouper and talapia, respectively. While the hardware differences between the WiFi and 3G models is negligible, and most things are interchangeable (ie: kernels, recoveries, etc.), the updates are NOT, and you need to pick the correct one for your platform. For the 3G models, this means the 'nakasig' version.
However, the first thing the OTA update does is validate the integrity of the system. In addition to checking about 200 files in the /system partition, it also looks at the device itself. Specifically:
assert(file_getprop("/system/build.prop", "ro.build.fingerprint") == "google/nakasig/tilapia:4.2/JOP40C/527662:user/release-keys" ||
file_getprop("/system/build.prop", "ro.build.fingerprint") == "google/nakasig/tilapia:4.2.1/JOP40D/533553:user/release-keys");
assert(getprop("ro.product.device") == "talapia" ||
getprop("ro.build.product") == "talapia");
While the first part checks the build.prop file to see what the "ro.build.fingerprint" has defined, the latter (bolded) assert examines what the RECOVERY says the system is. This is where the problem lies. AFAIK, there are no 'talipia' versions of CWM or TWRP. All 3G users running custom recoveries are using the 'grouper' (ie: Wi-Fi only) version. And this is fine 99% of the time. But this is the 1% of the time when they are not compatible. As a result, when the updater script checks recovery, and is told that the system is 'grouper', it aborts the update.
I ran into this issue on both the latest versions of TWRP and CWM. I wasn't sure why, since I thought it just looked at build.prop which was OK. After speaking with oldblue910, he explained that it is getting that information not from build.prop, but from the custom recovery, which is why the update was failing (thanks to oldblue910 for the info!).
SO, I was left with one of two options. I could either restore the stock talipia recovery or modify the update zip to ignore this information. I chose the latter. I'm not sure why Google decided to even but this redundant check in place, since the build.prop fingerprint check should suffice to validate the hardware. Not to mention that the next part of the update is to assert check the majority of files in 'system' anyway, which would fail if it wasn't a 3G device. In any case, by removing the above bolded lines out of the updater-script, my tablet was able to be successfully updated to 4.2.1.
Since many other XDA users run custom recoveries, it is safe to say many other users will run into this issue as well. So I put my custom update online for anyone else to use.

A couple notes:
1) This update zip is completely identical to the Google version, outside of the talipia check removed.
2) This update should ONLY BE USED ON 3G NEXUS 7 MODELS. It will NOT work on Wi-Fi only versions.
3) All the other asserts are left in-tact, as they should be. So your 'system' needs to be mostly stock. It checks and patches about 200 files, and if any of them are modified, removed, frozen, etc., the update will fail.
4) The OTA update does NOT check or update the bootloader or kernel, so modifications or non-4.2-stock versions in those areas are fine. However, as stated in #3, mostly everything else should be stock.
5) If the update fails on a specific assert, it will explain what the problem is (ie: the specific apk or odex file). You will need to fix that before proceeding. If you run into an issue and require assistance, you will need to explain the exact error message.
6) As this is almost completely stock OTA update, you WILL lose root/custom recovery unless you take precautions to prevent them from being overwritten. To preserve root, you can use RootKeeper or a similar app to back it up. The latest version of CWM also will warn you if root is lost and apparently restore it for you. For the recovery side of things, the update puts that recovery-recovery file on the system. You can either manually remove it via adb shell (BEFORE REBOOTING AFTER THE UPDATE), or in CWM (and possibly TWRP's case), it should warn you that you might lose custom recovery after the update and ask if you want it to fix it for you (say yes).
Hopefully this helps others who ran into the same error as me. Enjoy!

I compiled a CWM image for tilapia, so now users can flash updates and roms for their device without trying to by-pass the safety checks. With everyone recommending flashing grouper recovery, people are going to keep flashing grouper roms and wonder why things aren't working correctly.
The two devices differ in more respects than a simple assert check, including having different recovery.fstab files, which are used to make and configure recovery.
Better to have proper recovery for our (unique) device instead of a grouper port. The CWM image is not touch, the touch sources are not open source and koush's online builder is not producing a working image at this time. I ported one by hand, but it is too buggy to release.
I'll add twrp to the post sometime later.

Thanks, that's definitely a better solution versus a work around.
Though the safety check bypassed in the OP wouldn't cause any issues since it was redundant and unnecessary. The OTA update already checks build.prop for the model info and all the apks/odexes it updates, so it would be impossible to flash it on a non-compatible device. But you raise a very valid point about incorrect ROMs and other things. The 3G unit probably needs it's own forum.
Did you have to make any real modifications to CWM outside of changing grouper to talapia?

The 3G unit probably needs it's own forum.

Woohoo! Thanks.

I had some issues when I did the update. It gave me some errors, and aborted, but then I found a link that had the update and I got it to update. This happened on my n4 and n73g. Well, for some reason, the recoveries got deleted so I had to reinstall them. I was able to use the goo manager to restore TWRP on my N4, but it wasn't working on my N7 so I had to side load it. After this, I noticed that google now wasn't working on my n4, and the volume rocker on my n7 had some issues. I went in and wiped the cache and dalvik cache and rebooted. Google now works on my N4, and while the volume gets adjusted on my N7, it won't make the beep every time I push up or down on the rocker indicating the volume level. I haven't noticed any other issues, but I haven't really delved into my devices. I may try to do a factory wipe and return everything to stock just to see what went wrong in the first place and to see if I can do anything different I still can't figure out how to get ADB running on my computer, so yes I used one of the tool kits to load everything. I know the OP's position on tool kits, but I just can't figure out how to get ADB running manually, AND it takes so long to download and install everything unless I am installing things I don't even need.

Nexus 7 takju firmware update
Hi, while this is a very detailed description, I am still in need of help.
I just got a Google Nexus 7 from Google play store and it came with JVP15S firmware.
I understand that this is takju version of th edevice - I would like to upgrade it with the latest firmware but going through all the posts, I am totally lost.
I see upgrade files to upgrade from JOP40C to JOP40D - and see al ldifferent update combinations - but cannot fined one for JVP15S to JOP40D.
Also, all the updates are for different version "tilapia" and other fishes -- but none for takju (whatever that means)
Can someone direct me to right place to get the right updates/
Also I see a lot of posts and articles stating that Google is "pushing" the 4.2.1 Firmware JOP40D to Nexus 7 devices - how is this "pushing" manifest itself? What is the procedure for OTA update? Do I need to go to a place on Google to get it? Is it supposed to be downloaded automatically?
Hope someone can help.

Do you have the Galaxy Nexus or Nexus 7? If Galaxy Nexus, you of course would want to check those forums. As for the updates, you should normally see a notification alerting you of the update, but you can also check for it in settings/about phone/system updates. Otherwise the appropriate forum for your device will have links to the update files. Good luck!

lil help please
I updated to 4.2.1 with the OTA zip file using TWRP and voodoo root keeper installed. It flashed just fine. Rebooted with update. My root access is funky though. SuperSU is still there and I can access root file threw root explorer but I can't mount it as writable and when I install a new app that needs root access it never asks for it. Does superSU need to be updated? There is no update available for it.

Is your device rooted? Is this your first android device? You will get a little notification in the notification bar at the top saying your deivce has an update.. If you have not rooted, you will receive the first OTA in a day or two that will go from JVP15S to JOP40C. Then later, you will receive the update for JOP40D. Some people have had success at forcing the update by going to settings, apps, all, google framework services, and selecting force stop then clearing the data. You then go back into settings, about device, check for updates and check for update.

The N73G ships with an interim 4.2 build, which is JVP15S. There are some significant differences between this and JOP40C, which is the first update you will get out of the box. I imagine 4.2 wasn't fully finalized prior to hardware production, and they didn't want to hold it up until they were ready (wise choise!). In my case, within an hour after opening my N73G and turning it on, I had the 40C update notification. I applied this prior to rooting/modding/etc. ONLY after you are on 40C can you get the upgrade to 40D (4.2.1). Google pushes out incremental patch updates, so you can't skip a version.
So you have two options:
1) Apply update #1 and wait for #2 and then root/etc.
2) If you don't want to wait, and your device is still basically brand new and not setup (too much), AND assuming you want to root, customize, etc., just download the 4.2.1 system image from Google and fastboot flash it. You'll need to unlock the bootloader anyway, which will wipe your system, so now's a perfectly good time to do everything at once. Unlock bootloader, flash 4.2.1 stock (40D FULL IMAGE), flash custom recovery, install su zip, install any other mods (which is limited really to basic stuff and a custom kernel right now), enjoy.

Andoid 4.2.1 update

Thanks!
It is my first Android device.
I am trying to root it (unsuccessfully).
I was able to get the FASTBOOT unlock - but cannot root because of the drivers interface...
I did update the firmware by forcing via framework system. Had to do in two steps as it only upgrades one generation at a time.
By the way - I had the "takju" - now it is "tilapia" after "official OTA update.
I hope to get the rooting problem resolved - all instructions on the net are for older ROMs and I already screwed up my work laptop installing obsolete PDANET drivers which replaced the original drivers - so my device manager which originally saw my Nexus 7 as "Nexus 7" now sees it as "Android Phone Device". I do not know how to recvert back.
So now I am going to try my other laptop for rooting.
Hopefully I could find just a "professional step by step procedure - unlike many that I found on the net. Many people just happy to get on YouTube to show themselves off but the advice is half ass.
Thanks again for your help though I am half way through.
Best regards

I think you are either looking at really bad guides or simply making the rooting process much harder on yourself.
While some Android devices have more complicated unlocking/rooting/etc. requirements, that is not the case with Nexus devices - certainly not the Nexus7. The process couldn't be more simple. If you've already unlocked the bootloader, you are 1/3 of the way there. All you need to do is copy over a compatible "su" app zip to the device, install or run a custom recovery, install the su zip and voila - rooted.
If you already have fastboot running, that's the only tool you need. Download a custom recovery (CWM or TWRP) from a thread in this forum that is compatible, reboot into bootloader mode and install it:
fastboot flash recovery <recovery.img>
Then reboot into recovery mode (you can do this from bootloader), and you should be in CWM/TWRP. Then you simply install the SU zip using the menu on the screen.
It's a very simple process and does not require a special toolkit or anything like that.

Thank you for your reply and advice.
How do I place the "su zip" in the device and into which directory - I can try download directly to Nexus but needs to know where to place it.
Also what are "CWM" or "TWRP" And where do I place them for custom recovery procedure.
I apologize for my ignorance but Android is a complete new experience for me.

You can place the "su zip" anywhere you like on the internal storage. When you get into custom recovery (CWM or TWRP), you can select "Install ZIP" (or something along those lines) and it will bring up a file system explorer that will let you select the one you want to install.
CWM and TWRP are both custom recoveries. They replace the stock, and very useless, recovery and give you many more advanced features. Things like flashing zip files, making nandroid backups, etc. You need to flash them to your "recovery" partition. It's a very easy process, but will require some specialized software. There are many guides and toolkits (if that's what you want to use) online. Just make sure you use the Talipia recovery (which exists now in the 3G forum).

[Q] Rooted 5.0.1, OTA update to T-mo 5.1 offered, failed. How to proceed?

Hello everyone. My Nexus 6 has been running standard 5.0.1, which I rooted (using WugFresh's Nexus Root Toolkit - very useful software) . SuperSU has been installed, along with BusyBox, with TWRP as the custom recovery. My service is on T-Mobile, and just today my system update informed me that the 5.1 OTA update was ready to download and install. I allowed it the right to download and it claimed to be rebooting to install. Unfortunately, it rebooted into TWRP (I am guessing it expected the standard recovery)? I told TWRP it to simply reboot into the OS, and it appear the update has failed - nothing has changed. I'm still on 5.0.1 as shown in the settings etc.. Furthermore, attempting to check for System Updates again show no updates available; it seems it has "forgotten" that OTA 5.1 exists and/or assumes that it has already been pulled down properly? This is my first time updating a stock, yet rooted, ROM - I'm used to flashing or using another update system included in custom ROMs such as Cyanogen . I had hoped that since the OTA update was offered, it would have worked without the necessity to wipe my data as in a normal flash. I am guessing the error was in using the OTA update at all, or perhaps having TWRP installed? So I guess I am trying to figure out the best path forward from here.
I am to understand that the T-Mobile OTA 5.1 update activates a number of new features ,including VOLTE etc... so I want to be sure I get the correct ROM, as well as any baseband changes that may be necessary. I still have TWRP and the like, so I assume I could flash the update manually, if I was sure it was the right build and I got all the needed files. Now, I have to wonder, it appears that during the original OTA update, it did download the ROM somewhere. Perhaps I could find it on my device and select it in TWRP to update? Or would that not provide all the necessary files , overwrite something, or otherwise cause problems? Anyone point me in the correct direction perchance? Thanks.
Edit: I may have not been prompted for another OTA update because my battery was < 50%. Plugging it in and seeing if this changes anything. I read on Tmo's page that >50% battery is necessary to "qualify" for the update?
Also, according to https://support.t-mobile.com/docs/DOC-18109 - the Tmo 5.1 is "LMY47M". This build is not available yet at https://developers.google.com/android/nexus/images - only the "D" and "E" versions. Does this "M" version include VoLTE calling? I'm seeing discussion about these differing versions, yet very little solid information. I can't believe Google would split the ROM by carrier for a Nexus device! That's insane... having to look for all the custom ROMs that are built with the proper carrier specific build in mind!
a phone that is pure stock can take an ota. a phone that has any files changed, or not pure stock can not flash an ota, doesnt matter how many otas you try. you will have to flash the factory img.
So I should wait until 5.1 LMY47M is available and simply flash it via TWRP? Will I need to wipe anything at all when I flash it? Will I need to flash anything else, like Gapps? Rooting will need to be performed again? If I was running a custom ROM I'd know what to expect, but I'm a bit out of my element here.

you cant flash it in twrp. you can flash the factory img via fastboot while youre in the bootloader. or you can flash a 5.1 custom rom, that will be easier.

If you want to take the OTA, do the following:
Download the 5.0.1 factory zip.
Extract all of the files.
To unroot, fastboot flash the system.img.
Fastboot flash the stock recovery.img.
If you are unencrypted, fastboot flash the stock boot.img.

Furthermore, attempting to check for System Updates again show no updates available; it seems it has "forgotten" that OTA 5.1 exists and/or assumes that it has already been pulled down properly? This is my first time updating a stock, yet rooted, ROM - I'm used to flashing or using another update system included in custom ROMs such as Cyanogen . I had hoped that since the OTA update was offered, it would have worked without the necessity to wipe my data as in a normal flash. I am guessing the error was in using the OTA update at all, or perhaps having TWRP installed? So I guess I am trying to figure out the best path forward from here.
I am to understand that the T-Mobile OTA 5.1 update activates a number of new features ,including VOLTE etc... so I want to be sure I get the correct ROM, as well as any baseband changes that may be necessary. I still have TWRP and the like, so I assume I could flash the update manually, if I was sure it was the right build and I got all the needed files. Now, I have to wonder, it appears that during the original OTA update, it did download the ROM somewhere. Perhaps I could find it on my device and select it in TWRP to update? Or would that not provide all the necessary files , overwrite something, or otherwise cause problems? Anyone point me in the correct direction perchance? Thanks.
Edit: I may have not been prompted for another OTA update because my battery was < 50%. Plugging it in and seeing if this changes anything. I read on Tmo's page that >50% battery is necessary to "qualify" for the update?
Also, according to https://support.t-mobile.com/docs/DOC-18109 - the Tmo 5.1 is "LMY47M". This build is not available yet at https://developers.google.com/android/nexus/images - only the "D" and "E" versions. Does this "M" version include VoLTE calling? I'm seeing discussion about these differing versions, yet very little solid information. I can't believe Google would split the ROM by carrier for a Nexus device! That's insane... having to look for all the custom ROMs that are built with the proper carrier specific build in mind!

Update Available 2.19.401.2

Here you can download OTA, fresh firmware or system image to update your device.
OTA_M8_MINI_UL_K44_SENSE60_HTC_Europe_2.19.401.2-2.18.401.3_release_448048.zip [41.2 MB]
firmware.zip only [19.6 MB]
2.19.401.2_boot_system_2015-09-21--20-48-04_KOT49H.zip [TWRP] [1.15 GB]
Downloads: mega
​Let's see what's underneath
Main difference, I believe, is a security fix (libStageFright). I assume, that's it:
/system/framework/android.policy.jar
/system/framework/conscrypt.jar
/system/framework/framework3.jar
/system/lib/modules/moc_crypto.ko.sig.3.4.10
Zip also contains lots of *.p files (odexes, apk, jars mainly). Viewable through windows explorer. Don't know, what's that. Looks like a hash or a signature.
OTA includes firmware.zip containing {boot, hboot, recovery}, which can be opened through WinRAR (7Zip 15β failed). If you want just firmware, take it. Should be fastboot flashable.
*Additional notes*
Next lines describe my experience before I returned the device state to nearly stock.
Hello there. )
Want to share my experience. I have 2.18.401.3 and got promt to upgrade to 2.19.401.2.
Basically, as I get it, you need original recovery and that's it. (Pushed original kernel just in case. Also device is unlocked (tampered))
But under updating process the script mechanism checks some files to be original. Many system odexes, framework stuff and some libs.
My update failed on checking Books.odex (meanwhile, this app was deleted and redownloaded as user-app)
So, I might try to edit updater-script later or just copy files from update to folders they belong. The ota got a simple and obvious updater script for people who used to deal with them before. I'm considering delete parsing part or just push on screen what gives fail, but let updating happen. Need to be tested with system backup.

I tried to update from recent backup (the one before I changed kernel and deleted system apps), but facebook.odex didn't let me.
Finally, the very first backup did it. I took only system and boot, switched twrp recovery to htc, skipped all setup and installed OTA over fresh system.
Here you go. Now you have TWRP image of this update.
BTW, kernel version is different. CL build number is the same.
Hi,
can't I just flash it somehow with TWRP?
The standard update way does not work for me, because of changed *.odex files.
Already tried to flash original recovery etc.
Thanks

Unfortunately you cannot flash this with TWRP.
Is there a possibility to install this update (or any OTA updates) without having a "not-touched" system?
I could of course flash the TWRP recovery (what I've already done - it worked) but in that case I lose all my modifications. Is it possible to restore the TWRP recovery from that post and afterwards restore my own recovery without overwriting the system files which are needed to be up to date?
Thanks

You can try to restore the TWRP backup in the post. And yes, you will lose every mod since it is a backup of the stock, unrooted firmware.
The main problem of flashing the OTA zip would be that you will have to relock the bootloader before installing . So if you unlock it again, the internal storage will be wiped. The best way is to backup everything(Including the internal storage) and then proceed.
Actually, you can save your data while upgrading from non-worthy stock.
So, you may do this
Full backup, you never know what can go wrong.
Save or make a note of what you changed by yourself in system (from busybox to xposed & various modes.). You may use TB for sys-apps and simple file copying for modes. *
Restore updated system image from 1st post, so you have updated system.
See if it worked out and restore/reinstall your other system stuff.
* Remember, you still may access files of your twrp backup images through some archiver. Like I do using 7-Zip.
It's very important to save backup somewhere, cause it might be that my image can be not absolutely clean or can be not absolute right for your phone (like sell location difference). So it'll be easy to return back to working machine.
For this purposes I also setted up my TB for daily auto-backup of texts and settings and weekly backup of apps.
---
Don't sure about relock for upgrading. It seems to be launching, but it needs pure system and original boot & recovery. Some fastboot-magic helps here. That's how I did it after restoring to the very first backup.
So I have build number 2.18.161.3 rooted software on Vodafone, and received an OTA update build number 2.18.161.5-2.18.161.3. Obviously when I come to update it it goes to my custom recovery and can't go any further.
A couple of queries though I wanted to delete all the bloatware from my stock rom, after rooting I found I needed to S-Off as the bloatware keeps coming back on reboot so here are my queries.
Can I delete the APK files from the new OTA update and will this remove them if I install the OTA as a zip through custom recovery. Or can I use this update to wipe the bloatware from it all advice would be helpful

For bloatware removal just push a custom boot.img. Liberty kernel or dt2w presented here works fine, you may try them at least with making a backup of original kernel at first. (Custom made kernel might give you permission to write to /system without being s-off.)
I used liberty one, recently flashed the one with double tap to wake, works perfectly fine. Even sd is fine.
I'm not into kernels, perhaps as long as they suit your device they are fine.
OTA have its script, if it has such strings or if you write it into the script, you may delete some apps. Maybe, didn't try nothing with ota scripting. It easier to find working universal bloatware removal script as flashable zip package.
Otherwise, ota just adds some stuff or replaces current stuff.

If it has EE applications then it is an EE branded phone. Your updates will arrive differently and will have a different software number. So using the Europe zip will not help.

Excellent thanks for the reply so in short,
Grab the downloads from above (4 in total?)
Push and override existing TWRP recovery back to stock recovery (Dumbass Details would be helpful as I have not done this in ages)
copy the ADB the new rom to the phone (Again please forgive me as I have not done this in a few years need a memory jog)
Again thanks in advance

If you'll ask more specificly, I'll provide even shorter reply. )
As I get it, you ask for some short check-list / instruction
You need one of three files I uploaded, based on what do you want. )
You can flash big 1 gb system image v2.19.401.2 through twrp.
You can grab small upgrade package and update your 2.18.401.3 by yourself to have 2.19.401.2. Original firmware and fresh rom state might be needed.
You have other needs, you need just freshest kernel or etc., you grab firmware package and try hook it with bootloader or unzip and get the thing you need.
Pick the option and I'll write simple instruction.
I forget to read your previous post. ) So, you have 2.18.161.3 Vodafone. With root privileges (half-root, I assume)
So, yes, you need to restore original recovery of yours. Then it could handle the ota. If you can get it somewhere, you can update. You can get it in vodafone firmware (big package with everything) or if someone made recovery backup earlier.
My upload contains files for non-locked (operator's) devices.
As long as your phone has operator's rom, I can't give you proper advice. I assume, other recoveries/kernels/etc. might not be ok with your device due to hardware lock or difference.
But you can try always, if you sure you can handle it and revert or if you read on your situation enough. I can't advice you here on 100%.
But. If device is just a device, and roms are just roms (and some operator's special version is just a rom), you can flash other system and kernel and see what happens.
You may do a complete backup and save it somewhere and do one of the following:
Flash firmware.zip* contents, then go to TWRP and format all partitions except sdcard, then flash system image from above.
Just flash some custom 5.1.1 release. I use NostromoPop. It much smoother and it's lollipop.
*Firmware.zip contains boot, hboot, recovery. All that was for 2.19.401.2 but presumably can work separate. So you can get what you want and flash through adb. Like boot and hboot for proper device work on 2.19.401.2, or just recovery to try your vodafone ota w/o dramatic changes.
For futher safeness, you can backup hboot and boot or what you want.
I can recommend you to try custom sense-kernel for system write privileges.

Sorry to be a pain and your help is invaluable but just trying not to screw this up, My phone has been unlocked to all networks, and I would like either a stock rom bloatware free or a custom sense rom.
The phone is still S-On but I have unlocked the bootloader (Obviously). I Kept the stock rom hoping to use titanium backup to remove the bloat however I quickly found out the phone needed to be S-Off to remove it completely because as soon as the phone rebooted the bloatware re-installed it's self.
This is how I have the OTA update sat on my phone, I only Rooted for SU privs and put on TWRP everything else was stock. I did as a question in another post "Could I remove the APK from the OTA Zip on my phone then install it using TWRP and would that remove the bloat" but no response to that one.
Any help would be greatly recieved

Simply flash custom kernel: like liberty sense or stock sense w/ dt2w.
It will unlock the opportunity to write on every partition. I mean system, cache, etc.

Hi
I will assume you have the virus I have been seeing lately that wouldn't allow you to reset the phone, where in reset option the automatic restore option remains checked and you can't uncheck it.
The only solution is through TWRP, you need to enter TWRP, erase Cache, Data, System then flash the Lollipop ROM again or stock from here: http://forum.xda-developers.com/one...one-mini-2-t3250020/post63859743#post63859743
So there is no Rom available that's pretty much stock without bloatware that I can install with twrp? If not is there some idiots guide to putting my stock recovery back on thank you all again

Rooted Nexus 6 and updating to android 6.0

Hello all,
i rooted my nexus 6 and now that android 6.0 has been release i can't install the upgrade. My phone shows there is a system upgrade available. I have clicked to download the upgrade. Now its showing that a system upgrade has been downloaded and verified. Once i click on install update, it reboots to the teamwin. And to be honest, i don't really know if its taking the updated or how i can upgrade if possible.
can someone help me please?!!!!
Same answer every time. You can't get the OTA if you're rooted.
Options are :
- flash factory image (see sticky roll-up in general)
- flash a pre-rooted zip from recovery.
if you dont want to lose your data. just flash system.img, boot.img and recovery.img of your current build.
you can extract the images from the factory image...
Not only that, but by attempting to apply the OTA on a rooted device you risk bootlooping it, as I did with my Nexus 10 a couple of years ago.
Your best bet is to use Wugfresh's Nexus Root Toolkit (NRT). Since this is a major upgrade you can't use the "no wipe" option, so you'll lose any data that you haven't backed up first - photos, etc. - so do that before you do anything. Also take a TWRP backup of your current ROM and copy it to your PC so that at least you can recover to where you are now. NRT also has a backup option.
If you tell NRT that your current ROM is MRA58K (Android 6.0) and then tell it to flash stock and unroot, it will pull down all the required files before applying them to your Nexus. You can then re-root if you want to. It's a beautifully-engineered program, pretty well foolproof if you follow the instructions and choose the right ROM for your device.

Thats good news. What changed? Ever since that experience I haven't even tried an OTA. I was abroad at the time and lost the use of my Nexus 10 for most of the holiday.

OTA zips used to check individual files in system to ensure they matched before updating. It checks either md5 or sha hash. It didn't take account of every file or even files added by the users. so upgrading could cause issues.
Now, it checks the md5/hash of the entire system, which means all files are taken into account.. It will not flash of anything is changed.
Thanks - happy to roll you over to 19,400...

What is the purpose of each of the 3 different update zip files ?

Hi,
Sorry of this is a bit of a newbie question but:
What is the purpose of each of the 3 different update zip files ?
And do I have to apply them all - and in what order ?
In my case, I am about to update to B389, and I have downloaded 3 files for VIE-L29C636B389 (currently on VIE-L29C636B130), and I have an update.zip, an update_full_VIE-L29_hw_spcseas.zip and an update_data_full_public.zip.
I was planning on doing the first two by the dload method (with reboots in between), but the update_data_full_public.zip doesn't appear to have an update.app, so how do I load that ? (I do have TWRP on my phone, so could probably figure it out - eventually).
Cheers,
SZ
same question
I read somewhere that it should be flashed in that exact order. i'm guessing that is the same procedure as with auto OTA updates, except now we have rooted phones, so bye-bye to auto updates. I am currently on VIE-L29CB636B387 and i received an automatic Huawei notification of a new version (VIE-L29CB636B388) about a week ago. I tried to update to that version in System Update-Quick Update, but that didn't work (surprise!). There was no issue though as when I rebooted it just went back to 387. However, I now have a red "New Version" notification in my System Update. Please tell me how your upgrade went if you went ahead and flashed 389. I have the three files already from filefinder, i also have TWRP and/or I could use adb fastboot to install. Thanks in advance.
Hey,
I am not sure I want to proceed on the basis of something that somebody 'read somewhere' ....
Anyhow - I've not run these updates yet, as I wanted to backup my phone first, but TWRP keeps blowing up with an error in the middle of the backup, so I am not going to try anything until I get to the bottom of that.
Will let you know if/when I ever go ahead!
Cheers,

Hi,
TWRP blowing up during NAND backups? thats not a good thing. Upon the advice of a forum member (xzanium) I flashed TWRP 3.1.1-1 instead of TWRP-3.2.1-0-vienna. No hitches so far, solid backups and no hiccups in flashing SuperSU, also got xposed to work seamlessly and other stuff. I hope you are able to resolve the issue you mentioned and get around to getting VIE-L29CB636B389 on your phone.
Well good luck to you, and post here any progress if you would.
SZ,
I have an idea on what the purpose of each of the 3 different update zip files are for and whether you have to apply them all - and in what order.
Since I could make a NAND backup using TWRP without issues, and there was an OTA update notice for an upgrade to VIE-L29CB636B388 which I couldn't upgrade to while rooted, I decided to unroot in order to upgrade to that. First i did the requisite steps - uninstalled the xposed framework and proceeded with the full unroot with SuperSU. Then I performed the dload method to flash the update.app that I extracted from the update.zip.
It was here where i hit a snag. What followed was, I found out that Huawei needs a verified stock rom, meaning it has to be a fullOTA-MF-PV in order that the bootloader could be relocked. So I tried my luck and downloaded the stock ROM VIE-L29C636B370 and flashed that. Success! From there, and several auto upgrades later I was back to L29C636B370. Reinstalling my Google account also locked back FRP. At this point i am full stock EMUI 5
Now, to answer your question. When I tried to upgrade to VIE-L29C636B388 via system update quick update. I only saw one file - update.zip therefore this must the only one needed for incremental patches. The same holds true with update_data_full_public.zip as I later learned when I decided to use the proxy upgrade method in MT filefinder . It applied a 2nd patch. The third file, namely, update_full_VIE-L29_hw_spcseas.zip was not required for this incremental update. In fact, the update process was cut short and an error message appeared that the file could not be located, even though i copied that to the HwOUC folder. It appears that this was deleted before the fullOTA update could finish during the incremental update process. Clearly, this last zip is not necessary for incremental updates. So this must be the package which delivers the rest of the ROM, or the parts of it that needs to be changed.
So, obviously what "I read somewhere" was legit. I hope that answers your question.
cheers!

I'm doing it with all modules disabled.
What am I missing?

You may have to wait for the update over the internet, then once it starts there's more waiting for the installation to complete, plus you could end up with a "problem" error after everything seemed fine during the first 20 minutes. OTA updates will be less frustrating and faster using adb to sideload over USB.
This guide for Pixel 6 is a good reference for most Pixel 7 situations (the main difference with 7 is to patch, flash or restore init_boot.img instead of boot.img).

If it helps..
I just happened to use my P7 as an example in a different thread.
[Discussion] Magisk - The Age of Zygisk - Post # 2,648​
Includes a Github link showing the modification to the flash-all script I use.
Includes a Pastbin link showing my update from Nov -> Dec.
Cheers.
PS.
Just to be clear, I (always) use full factory images for Pixel updates.
- Factory Images for Nexus and Pixel Devices
Not the incremental OTA(s).
- Full OTA Images for Nexus and Pixel Devices

Thanks, I want to try the adb to sideload method, but I have doubts. it is technically detrimental to update flashing factory image / ota over the previous factory image? It's been years since my last rooted phone and I remember people suggested not to do this (I think they recommended full wipe), but I don't know how it goes today.

Helps me! Learned some new stuff and added it to my notes.

Flashing the OTA doesn't wipe but factory will wipe if you run flash-all (.bat for Windows, .sh for Linux) without removing the -w argument on the fastboot line. i.e., Flashing the OTA will get you updated without losing anything but flashing factory is preferable for updates as long as wiping is disabled.
The factory zip is what PixelFlasher uses for non-destructive updates without having to uninstall Magisk. It's the easiest way to update a rooted Pixel, but mistakes still happen. Like its developer recommends, best to tackle command line methods before jumping into GUI methods.
As far as detrimental flashing goes, with Pixels and stock firmware you would have to stray far off the trail to break the phone.

Thank you manjaroid! Finally I updated flashing the Dec factory image with flash-all.bat script (-w removed) and rerooted with the new patched init_boot.img it's really easy but we have doubts the first time. You answered my question (flashing factory is preferable for updates), but why is that? I want to understand a little bit more. And whats the difference between an destructive/non-destructive update?

How I might explain it is OTA's are incremental updates that patch specific particular parts of the system. You might want to look at it like in an instance of laying a foundation/base, OTA's would be like replacing cracked/broken/weak sections with bricks. As time goes on and more OTA's are released and patched, more of the foundation is put together by more and more bricks -- which may be (quick and easy) or may not be (not a single solid base/structure) more detrimental as time progresses (cumulative patches may inadvertently cause glitches/bugs down the road vs. a full factory [non-patch] update). While holding up upon that patchworks of bricks among the "foundation" is perfectly serviceable and can well enough hold up whatever structure is placed on it, having a whole piece unpatched foundation (Full Factory image) is still preferable as a base/foundation because implementing that "foundation" (versus a foundation with various patchworks in it [OTA's]) would include in itself whatever fix/reinforcement the bricks patched(cracked/broken/weak sections) [what the OTA's did] while establishing a complete whole unseparated-in-any-place base/foundation.
So, in the end, it's preferable to have a solid, whole, almost from-scratch Full Factory image firmware update than a circumstance of patching upon patching the way OTA's implement their updates.
Also, unless you update the device by OTA's from the OS and it's as simple as that (although it can take pretty long; upwards to seemingly 20 minutes) -- because you have an locked bootloader -- the only other way to install an OTA is sideloading it which means you have to download it to a computer, boot up the device in a certain way, and run a command on the computer; which is very similar and not too much different than what you would do if updating using a Full Factory image anyway -- download image (Full Factory instead of OTA), load up device in a certain way (bootloader/fastboot mode instead of recovery) and run a command (flash-all.bat instead of adb sideload .zip); one major difference is you must edit the flash-all.bat script so it doesn't delete user data and factory reset the device.
Sorry for the long explanation, but that is why IMHO it is more preferable to update using the Full Factory image than OTA...

Not a good choice of words ("non-destructive updates"). That's kinda redundant since most of us don't intend to lose anything when updating. fastboot has to be told to wipe or not so calling it non-destructive flashing would have made better sense.
