I flash with eva_l09b391_nocheckrecovery, full unroot (SuperSU offers to restore stock recovery I select "YES".
Than reboot the phone. In system update 391 appears. Select it for download and install.
After reboot the EMUI updates runs for 10-15% and than Software install failed
Failed to apply the differential update files. Please download a package in recovery mode.

What I do wrong ?

Flash from Fastboot stock (build you are upgrading from) or non- check recovery, not the recovery opted by SuperSU.
And in System Update, its settings, select Full Update, it shall download 2 GB and let it do the OTA update then

If it would still fail (?), boot to stock/no-check recovery, choose Factory Reset, and go again for OTA update.

Yes I flash with eva_l09b391_nocheckrecovery.img from the firs link.
I don't know how to extract stock recovery from 386 (which is mine) to flash with it, unroot and try again.

I did again full unroot from supersu, install the eva_l09b391_nocheckrecovery.img reboot the device.
Select full update from menu - Installed successful. After that reboot, and update to latest 394
using twrp-3.1.1-1-eva.img and supersu.

Short procedure:
unroot, stock recovery, update to latest, install twrp and root.

All works fine, thanks for all !

Somehow after updating to 391 the bl was locked, so now unlock again all new setup :/

Yes, but now I see that version is 2.81, not 2.82. I Will try tonight with new one.
According this thread Which version exactly should I use, this one ?

Use exactly as I wrote in my cited post, resources are in the corresponding XDA thread I gave you, please READ there you can also download from my Mega (SuperSU 2.82 permissive, V4A, they worked for me on b386 and b393, currently didn't root my b394 yet)
https://mega.nz/#F!w41RmZKB!IG53JadhjUKgFK8anbctIw
(System/Nougat/SuperSU directories)

If you do it different or use something else, don't ask :)

Click to expand...
1) Install Firmware Finder to the phone, search for e.g. EVA-L09c432b386, find the corresponding FullOTA-MF-PV package, open Download, select Update,zip and download
https://forum.xda-developers.com/tools/general/huawei-firmware-finder-team-mt-t3469146/amp/

2) Copy downloaded Update.zip to PC and unzip the archive.
Install Huawei Update Extractor to PC, run, open Update.app (from the unzipped Update.zip), locate recovery.img and Extract it
https://forum.xda-developers.com/showthread.php?t=2433454

Not recovery2.img but recovery.img. That will be your extracted stock recovery.

Problem:'
Last month, all such downloads from FF fail for me. I've tried to download same files several tines, at different time of day, over different WLANs, it failled after 20% or 80%, but it failed each time. I've tried various files from various builds, all downloads failed.

But you can successfully download the following way: From FF, locate and check mark your e.g. Update.zip but instead of Download action, use Share action. Select Clipboard to share. Open Browser, paste the URL from Clipboard into the navigation bar, and start downloading.

Browser will never ever fail to download the same file, from sane URL, where FF fails to download it each and every time

PS: To extract recovery.img, you don't need 2 GB FullOTA MF (PV). Ten times smaller OTA-MF is ok, however its Update.app does not contain all system partitions but it does contain recovery.img you need.

Needless to say, FF fails to download even 146 MB update.zip from e.g. OTA-MF b394, while Chrome completes the download in few minutes. But FF shares the URL to download from :)

I have L09C432B390 ROM with magisk root and unlocked bootloader. And when I flash your recovery and try to boot on it with reboot recovery command I get boot loop and if I flash original recovery image it's works perfectly. How can I fox this issue? With your recovery image the won't boot on it..

Many thanks to @Atarii for this awesome Recovery.
Keep up this good work :)
May you can do it also for EVA-L29?
This would be very helpful
I managed to use it for an HWOTA.zip for going back from my Custom Rom to Huawei Firmware very easily.
But I couldn't do without this Recovery.
Cheers :)

This recovery work perfectly, I used it to return stock after install moonlight (it's a fantastic ROM but I had to give my phone to Huawei center) and, after install b394 I also got the ota of b395 so is perfect two times. Great job @Atarii.

Just to confirm, the nocheck recovery works fine with the C432B397 firmware that was released today. Changes include:
  • 1st January Google patches
  • Adds 3D panorama mode in camera
  • Gallery now features a recycle bin that retains deleted photos up to 30 days
  • Adds a security procedure that requires you to enter your lock screen password every three days
  • Adds VoLTE
  • Adds VoWifi
  • Optimises power consumption for longer use
