back to stock recovery - HTC One A9

I have HTC one a9 with build number 1.58.709.1. Rooted and unlocked bootload and have twrp. Never flash any roms.
I want to remove every thing that prevent ota to be installed.
I think twrp will cause problem for ota. So how can I remove it an have stock recovery?
The ruu is not available for x.xxx.709.x in web. But I find ota matching my build number. Is that help?

Yes, you can extract the recovery.img using this tool.

Thanks.
I will do that. Then what should I do with it? Flash it?
And I remember that after installing twrp I had format my internal storage to make it decrypted. How can I undo that?

Yes, you can flash the extracted recovery image via recovery.
For encryption, if you do the OTA update and let it reboot stock, it will automatically encrypt your data. Obviously, first boot might take a long time. If you interrupt it, you will lose your data.

After restoring stock recovery, I need to unroot and lock boot loader for getting ota?

To manually install an OTA, definitely not. All you need is the stock recovery, a COMPLETELY untouched system (never mounted r/w), and the correct ota.zip.

Is there a way to check if system modified or not?
I read before that some ota are patches asn some of them are complete os. They said only when you want to install patches you need untouched system partition.
The next ota will be android 7. So it format every partitions and modified system cannot make any problem.
Is it correct?

No, the Nougat OTA (for US unlocked at least) patched the existing system partition.
The easiest way to check is to attempt to install the OTA with the stock recovery. It will tell you.
If I were you, I'd flash stock recovery and system from your current RUU, then OTA update.
Another option is to just install the RUU. That will revert your phone to completely stock, wipe your data, and allow you to start fresh.

That's the problem. There is no ruu available for my build number (1.58.709.1.). I just find an ota with this bluid number. The ota did not contain a system.img.

Yes. I flash stock recovery. then I try to side load the ota to phone. Adb did not recognize device in boot loader or recovery. I don't know why. I use 15 sec Adb installer. It said it installs drivers.
Update: I notice that in bootloader on top of screen there is writing: "software status: official".
Does that mean system partition is untouched?

If your stock recovery has a menu, you can copy the OTA.zip to your phone or sdcard and install from there.

It said system partition has mounted r/w.
What can I do now? There is no ruu with my build number in web. I think s-off is my only way to get android 7? Or maybe htc publish ruu for all regions this time?
If I found system partition backup of my build number in web, is restoring it help?
update:if previous ota (1.56.709.70) has system image in it can i flash that sysem.img?
and do i have to install twrp again to be able to flash system.img?

System backups found online can be unreliable for OTA updates. Here's what I suggest:
Install TWRP to your phone, and backup your current boot and system to an external sd. Be sure that the 1.58.709.1 ota.zip is located on your external sd as well.
Extract the system image from 1.56.709.70 RUU, place it on your external sd card as well, and flash it in TWRP.
Reboot to stock recovery and install the 1.58.709.1 ota. It should verify the 1.56.709.70 system and patch it.
That should complete successfully. When it reboots, it will take a long time since it will encrypt data by default.
You will then be 1.58.709.1 stock and be able to take OTA updates.
If something doesn't complete successfully, stop and post the log here.

Unfortunately the latest ruu for Taiwan is 1.27.709.x for android 6.0.0. I download 1.56.709.70 ota. It doesn't contain system image too. 1.56 was first update if android 6.0.1 and 1.27 was latest build of android 6.0. I think system image of 1.27 is same as 1.5x updates.
I want to try your way in 1.27.

Ok, that MIGHT work with system images only. 1.2x boot and recovery images will not boot on 1.5x firmware.

6. try to install 1.58 ota. unsuccessful. see image 2.
7. boot to system. it got stuck in bootloop.

Did you swipe to allow system to be mounted r/w in TWRP? If you did, that could be the problem.
If not, you can attempt to use the system backups that you can download. You may have the same result, though.
Have you tried using HTC sync manager from download mode? Sometimes that will RUU your phone. Your data would be wiped though.

Yes. I allow twrp to mount system as r/w because without this twrp cannot flash system.img.
I don't understand last paragraph. Will you please explain more?

TWRP can flash the image without mounting system r/w. That is most likely what is breaking your OTA. Once the system is mounted r/w, it breaks dm-verity, even if you make no modifications.
You should start over and not allow system to be mounted r/w.
HTC sync manager can RUU most modern devices if you connect them in download mode with the software open.
It can be downloaded from HTC's website. I normally wouldn't recommend it since it usually interferes with fastboot and adb if it is installed.

you need to be STOCK for OTA to work. Custom recovery, custom rom, any modifications to system etc will all prevent OTA from working.

how to make it sure/check it , that im using stock ROM or not
and how to uninstall CWM ?
Flash stock recovery and did you make any modifications to stock ROM or flash a custom ROM? If so you need to undo all mods and replace anything you removed that is part of system, or just install stock.

I'm having the same problem, I had already flashed /system and /boot back to stock, just didn't flash recovery (because it wasn't needed before on KK), now I've flashed everything back to stock, but now it says "system up to date" how do i solve this now? I did grab the ota zip, so maybe i can force it to flash with that zip on the stock recovery?

Yeah, download ota file and sideload it, otherwise you're waiting for the ota to become available to you again via download on device.

Use cmd prompt to use adb. You'll need android SDK if you don't have it. Navigate in cmd where your adb is (also have your update.zip in that directory). Run adb and then adb reboot boot loader, wait for boot loader, on device go to recovery. Once recovery is up, press vol up while holding power to access menu, go to apply update from adb then back in cmd run adb sideload update.zip

check out the toolkit from wugfresh, that might be the easiest way for you if you don't know what you're doing... maybe take some notes so that you do remember what you're doing for future.

Should I unroot before installing latest OTA update?

I've got a Nexus 5 with Android 5.0. I've had it rooted and unlocked using SkipSoft Unified Android Toolkit. I recently got a notification for an OTA update for 5.0.1. When I tried to install it, it downloaded ok but upon restarting it dropped me into teamwin recovery menu with options for: Install, Wipe, Backup, Restore, Mount, Settings, Advanced, Reboot. Not knowing what to do I clicked on Reboot -> System which booted back into the phone. Nothing changed or got installed.
Does anyone know how I can apply the latest OTA update? Do I have to unroot first, apply and then re-root? Does the Toolkit have support for 5.0.1 rooting yet?
TIA
You must be 100% stock to update so yes, you need to fully unroot.
Though you should just fastboot flash the system.img and boot.img
Don't use toolkits. Do things manually. You can either flash SuperSU from recovery or use cf-auto root from a computer.
Its very easy, there is flashable 5.0 stock ROM, I dirty flashed, or you can do it like rootSU said via fastboot, root has been lost, then I flashed stock recovery via fastboot, there is thread for recoveries, then I upgraded via ota and flashed twrp via fastboot and flashed SuperSU to gain root and custom kernel.
My way is much quicker though as you flash 5.0.1 system and boot straight away. Nothing else.

Ok, I'm not 100% sure I understood everything you said. I've downloaded the 5.0.1 update from here: https://developers.google.com/android/nexus/images. Using 7zip, I noticed the system.img and boot.img is contained in the tgz file (along with several other files). Do I just extract just those two files? And then what do I do in Teamwin?
Will all my apps and data persist?
TIA

Boot into bootloader
fastboot flash system system.img
fastboot flash boot boot.img
Boot into Lollipop
You didn't touch userdata.img so it doesn't touch the data partition, although a wipe is usually recommended anyways because it's a new version of Android.

Flash back stock boot and you'll be back to stock, as long as you didn't modify any of the other partitions (/system, /vendor, /product). And flash back recovery using adb.
Get stock boot by downloading your firmware from http://hwmt.ru/oth/HWFF/info/view.php?find_model=mha
Then download Huawei Update Extractor https://forum.xda-developers.com/showthread.php?t=2433454
Open it up and open update.app which you extracted from update.zip. Right click on BOOT and extract, same with recovery.
Flash back boot using twrp and 'fastboot flash recovery recovery.img' to flash back stock boot.

You will have to flash back hw and public zips for your build. There's a folder (hw_init) in /data/ that gets wiped when you format data, it contain apps (system update for example) and the theme engine.
So you will have to flash back TWRP again and decrypt again if you went back to stock, else you won't be able to flash the zips. After that you can flash back stock boot and recovery, and you *should* be able to update via OTA.
Here's a little guide for getting HW and public for your build: https://forum.xda-developers.com/showpost.php?p=71302827&postcount=627
Also, question: What update are you trying to apply? It might just be that it's not approved by Huawei yet, and that makes it impossible to install using Firmware Finder.
And if you're trying the Dload method, it won't work. Only 2 offline firmwares have been released.
Edit: I should learn to read. So you're trying Dload? Yeah, that won't work.
I guess you could install your current full firmware using Firmware Finder, but for that you'd still need to flash back HW and Public so you can actually see the System Update button.
And that means flashing back TWRP, and flashing to /data requires decrypting, so you'd have to do that as well.

Thanks for that. Do I have to do a full wipe if coming from a MHA-L09C34B122?

Exact steps back to Stock with a clean "System Image"

Hi guys,
what are the exact steps to go back to stock with a clean "System Image" for taking ota updates?
I've made a clean backup via "System Image" in twrp with an unmodified system as stated in the twrp thread before i did anything else (root, etc.).
Thank you in advance
You dont need to. You can flash via ruu zip. Just use the same firmware as the phone is on now.

Thank's for the reply. But this was not the questions (please don' be mad). But what if i want to?
I did backup the stock recovery and a System Image backup prior to flashing TWRP via fastboot boot twrp-3.1.1-0-ocn.img (point 4/6 in the twrp thread).
What would be the exact steps? Can I just boot normal to twrp-recovery an restore the system image and the stock recovery? Like this:
Thank you in advance

Flashing RUU via recovery breaks the ability to take OTAs, correct? Where as running RUU exe doesn't? I think i read this somewhere in the xda ruu collection thread.

If you are rooted and/or have TWRP installed, then you need to restore the stock boot and/or recovery images before starting the update.
Then I will lose root access?
Not if you do it properly.
If you're using TWRP, then you'll have to restore the stock recovery.
If you're rooted then you can restore the stock boot using Magisk>Uninstall Magisk>Restore images but don't reboot or you'll lose root.
Then download and install the incremental update manually. Then install Magisk to the inactive slot and reboot.

1) Update software but DO NOT REBOOT
2) Open Magisk > tap install > tap Install to inactive slot > NOW reboot.
Make sure you disable any and all modules first. No need to uninstall, just disable them. Mainly just a precaution. Possibly remove security from the lockscreen too for good measure.
I lost root the other day actually forgetting to properly install Magisk before rebooting and now I have to buy a laptop just to root again.

Thanks @BillGoss, your instructions are perfect. Work like a charm.
Anyone have the stock firmware or stock image for 11.0.12.12.KB05AA? Trying to root it.

Use TWRP: https://forum.xda-developers.com/t/guide-rooting-oos-with-twrp.4327417/
since i did it manually and ended up with no boot.img backup from magisk, i had to manually extract boot.img from my last ota 11.0.11.11.KB05AA and reflash it through fastboot. then it let me update and i rerooted.
I get the notification but can't even try it because when i tap on it, it does nothing.

I managed to install the update, I used oxygen updater to download the update, used restore images option in magisk, installed update (DID NOT REBOOT), used install to inactive slot in magisk, then rebooted.
Seems like it all went well.

Do I have root and twrp, what should I restore? Only recovery? If so, you have maybe some stock for 11.0.11.11 kb05ba? I don't know why, but I only have a copy of the boot.

What don't you understand in post #5? You said you're rooted. So post #5 tells you what to do.

Sorry Bill, I get it all now. I just have to do as You wrote:
1) restore the stock boot using Magisk>Uninstall Magisk>Restore images but don't reboot or you'll lose root
2) install update manually, System update>Gear icon (local upgrade)
3) install Magisk to the inactive slot and reboot
Last question, where or how to download update manually?

Ah, well that's tricky if it's not available from OnePlus or the XDA rom thread. I believe Oxygen updater app will give you the rom also, but I've never used it.
Edit: just read your post again and I'm confused: what rom exactly are you looking for?
This thread is about ending up on 11.0.12.12.KB05AA
And if you're looking for that one you'll find it in https://forum.xda-developers.com/t/updates-thread.4188149/post-86165983
