Need help to create a TWRP update from OTA

I just receveid an OTA update, but the installation stuck because the system is rooted.
I found the update.zip file on my Handy, but it contains some directory (Meta-inf, patch and system) and a big file update.app that I believe contais all the update file.
Is it possible to extract the file from update.app and then create an update that can I launche from TWRP? And if so how could I do it?
Thanks

You can't.
flash back a stock recovery.

After ulocking bootloader and root the OTA didn't work with original recovery that's why I wanto to create an update that works with TWRP

did you try?

Yes I reinstalled the original recovery that you can find in t he root package and I completely unroot the phone using the unroot command in SuperSu.
Then I launch the update but after reboot it stuck at 11%, so I create the dload folder in my handy memory and copied there the content of update.zip and then forced the update. In this case, after reboot, it load until 99% that it reboot, but the installed version is still the 170 and not the 188.

Here worked, from post #393 to # 397 and #400
Stock recovery in root zip maybe too old.
Edit:
Ops perhaps it work on full update packages.

Sorry, forgot link: http://forum.xda-developers.com/p8l...-lite-android-6-0-marshmallow-t3305550/page40

You need the Huawei Update Extractor Tool, and do the following:
Load the UPDATE.APP file inside the HUET
Extract boot.img, system.img, and cust.img, from UPDATE.APP inside the HUET
Flash the respective files via Fastboot

so if I am on Marshmallow beta, should I flash the recovery that comes with the marshmallow or the recovery of the B052 rom ?

If you have to, flash the B052 recovery... you can always flash the Marshmallow recovery if it doesn't let you update.
I only flashed boot.img, cust.img, and system.img, when I upgraded; didn't flash Marshmallow's recovery at all.
Don't think you can even get OTA updates on the Marshmallow beta anyway (even via a normal bootloader-locked device).

Sorry for my late answer but I was travelling only with a Mac and I couldn't use Huaweu Update extractor.
This are the file that you can find in UpdateApp 188:
00.SHA256rsa.img
01.crc.img
02.curver.img
03.verlist.img
04.efi.img
05.fastboot1.img
06.boot.img
07.recovery.img
08.recovery2.img
11.cache.img
13.dtimage.img
14.dsp.img
15.fastboot.img
16.hifi.img
17.mcuimage.img
18.modemimage.img
19.modemnvm1.img
20.teeos.img
21.trustfirmware.img
And also the following directory:
META-INF
patch
system
Which file should I install, I didn't find a system.img and there are two different recovery
Thanks

You should not install any OTA with TWRP...
Flash back the stock recovery, update, then flash the twrp again, it's way easier and more secure, than doing a flashable zip from an OTA update without knowing what to do with the file within.
The OTA updates usually doesn't contain the SYSTEM.IMG file you are looking for, it contains individual files and scripts to patch up the current system partition to work with the new update.
From the two recoveries you should use the RECOVERY.IMG (the one without the 2 in it).
But again, I do recommend to flash the original recovery(not the one in the update), do the update, and put twrp back.

Where can I find the original recovery from ALE-L21C432B170, so that I can flash the original recovery again?
TIA

I found the original recovery and flashed it then I did a complete unroot and tried again to do the OTA update but it stopped at 11%.
Is there a different way to update?

Is it possible to update to B381 (via OTA update) having a custom recovery?

Hi all,
I currently have a P9 Lite with VNS-L31C432B371 firmware installed.
Recently, I received the VNS-L31C432B381 update via OTA. Unfortunately, when the phone reboots into recovery mode, the update does not even start; instead, I get redirected to the custom recovery (TWRP 3.1.0.-2, system partition read-only) "homescreen".
Is there a way to update to B381 without wiping the entire phone?
Thank you for your time.

The OTA update system uses the EMUI stock recovery so no, there is no way you can update your phone through the updater by using the custom recovery

Yes.
Download your build's update.zip, extract the zip to desktop, you'll then have an update.app (you probably need the full ~2GB build, not OTA, e.g I use B370);
Extract recovery.img from the update.app via HuaweiUpdateExtractor;
boot to bootloader;
fastboot flash recovery recovery.img.
Done.

I succeeded in extracting and installing the recovery from the update.zip. Unfortunately the OTA failed anyway.
At this point, I think I should just wipe the phone and install the complete update from here.

Well I , like you, had a custom recovery. The 3-button method didn't work for me and even after restoring the stock recovery I was unable to install the update.
I unpacked the Update.APP file and flashed through fastboot the BOOT, RECOVERY, VENDOR and SYSTEM .img files and I was succesful but now I have the Model number as generic_a15 and Build number NRD90M test-keys. I can only assume some of the other img files carry the information about my phone. At the moment is stable enough but I can't open the Security menu.
If someone has any idea on how to flash the other img files, please let me know

I only have old oeminfo.img packages, do you know how I can build one? There is a PRODUCT.img but it is considerably bigger than the oeminfo package that I have seen.
I flashed all the old B370 files, update.zip and update...hw_eu.zip, with DC Phoneix (a non free tool but saved me from.a bricked phone). After that, I flashed the new package and got the Security settings and Developer Options to work again.

Hi,
1) wipe Dalvik & cache, flash stock recovery of b370, and then do like you wanna update to b380 using firmware finder, (use the big file)
or
2) rollback to MM : flash oeminfo for your location (recommended) , flash Rollback Package via dload , and then flash stock B160 via dload.
or
3) remove root from SuperSu app, then use Rocatex uninstaller

[TUTORIAL-easiest] Rebranding to L19 C10 (Russian, EU) for Oreo update + video

Hi, I will show you the most easiest way to get oreo update (emui 8).
you must have installed twrp and unlocked bootloader.
1. Download this https://forum.xda-developers.com/honor-8/development/tool-srk-tool-huawei-bootloader-root-t3470823
2. Press 7 then 9, next 7 and 5.
3. Now download 2 files: http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1276/g104/v64076/f1/full/update.zip thanks to @jithendrav83
https://www.hihonor.com/uk/support/details/index.html?DOC_ID=92135 <- first
4. flash it by dload method
thats all. Now update your phone by huawei built-in updater or firmware finder.
But for me the best option is unlocking bootloader again, root then flashing by this tutorial: https://forum.xda-developers.com/honor-8/how-to/guide-flashing-unapproved-firmwares-t3668306
(method 2)
VIDEO OF EMUI 8 ON HONOR 8:
https://www.youtube.com/watch?v=VVe9gsyVxd0&feature=youtu.be

As you wrote, then the update will wait forever.
At this location you can, because. on the Russian version in the folder "cust" is your region. I recommend that you visit the Russian forum 4PDA.RU

Hi,
Would this work on Honor 8 single Sim device (I've FRD-L02)?

As per my guide, you only lose it if you're rebranding to AL/DL (chinese). Rebranding from L02, L04 to L09 is perfectly safe (I'm running L09C10 on my L04)

So best way to get Oreo on L04 is to rebrand with this method and redlotus to the Russian EU firmware and everything will work?

Hi,
I rebranded FRD-L02 to FRD-L19C10 and tried above steps. Installed Oreo by redlotus method. But got "data corrupted" menu and I formatted data. Now phone won't boot. Then I tried unlocking bootloader and phone booted. But sw version still shows B95 and its on Oreo. Looks like cust/region part is not flashed. Tried installing Twrp 3.2.1.0 and the one in Multi-tool, but phone won't boot to recovery. Its going into error mode. Any suggestions appreciated. Thanks.

If you look at the XML File you used for the RedLotus method, you can see that there are two versions in it (L09C10 and L19C10). I suppose that's the reason why it's bugging for you.
Don't know for sure though. Trying that method now too, will report back if that's really the problem.

To rebrand, you need an unlock bootloader.
1. Download the C10 oeminfo file https://drive.google.com/file/d/1VtOeGQ9GnKvcSVgraPP6-go6HCRbpyBB/view?usp=drivesdk. It is a zip file, extract it to find an img file. Reboot to TWRP and select Install Image and install the file to oeminfo partition.
2. Perform a complete factory reset in TWRP.
3. Download the latest Nougat (3 files package) for FRD-L09C10 through Firmware Finder. Flash it using HuRupdater https://forum.xda-developers.com/ho...l-flash-official-firmware-recovery-t3769279/.
4. After the flash is complete, reboot the device, unlock the bootloader again and flash TWRP.
5. Download the latest Oreo build for FRD-L09C10 through Firmware Finder. Using HuRupdater flash the three Oreo firmware files. Don't perform a factory reset this time.
6. Reboot your device. You're now on Oreo.

Doesn't work for me. Always results in a bootloop with "Your device is unlocked..." etc.
Same with RedLotus too. I don't know if it's the firmware you linked or the recoveries, but ehh... nah, probably gonna go back to where I was before.

Try to install Service ROM from SD card using dload method.
Link:
https://androidhost.ru/41d
Follow instructions in file "ReleaseDoc". (Read everything carefully before doing anything).
Through this process, your data will be deleted and bootloader will be locked again.
Dload method works with Stock Recovery only, you have to install Stock Recovery first.

Hey dude !!
So you bricked the device ....
I don't know why but if you want B412 firmware
you can use @-Alf- guide and re-upgrade via Firmware Finder
to B370 fullota-mf-pv first, then to B412 fullota-mf...
Or download a previous from B412 firmware (ex: VNS-L31C432B410 fullota-mf)
and use HuRupdater method to flash the firmware.
Extract then stock recovery from B410 via Huawei Extractor and flash it via TWRP.
Re-update finally to B412 using Firmware Finder.
I can help you doing this, worked on my ex device but i can't guarantee 100%.
