NTX-L29C432B180-FULL OTA update not possible...

Hallo everybody.
Summarizing: with a new, clear Huawei Mate 8 (HUAWEI NXT-L29) I unlocked the bootloader (default Huawei procedure).
I rooted the smartphone using SuperSU and all's perfect - my apps require and gain root permissions.
No, a new OTA upload comes into being.
I try to install: the smartphone reboots and remains stuck on "Your device has been unlocked and can't be trusted" or whatever...
I try to "fastboot oem lock ******" (the code I obtained unlocking), but it tells me "FAILED (remote: root type is risk)".
I try to reflash the stock ROM (to do a hard reset), either by the "dload" or the "*#*#2846579#*#*" method: it stays stuck on "Your device has been unlocked and can't be trusted" or whatever...
Any advice? Where am I wrong? And what to do next to update the ROM?
Thank you!

Any suggestion? Come on, guys, you're the best...

First thing to flash OTA - stock recovery. Flash it from fast boot and try again.

Can you tell me step by step? And where to download files?

I'm sorry, your way doesn't work.
The RECOVERY.img is flashed good, but when I try to install the UPDATE.APP, it remains stuck on "Your device has been unlocked and can't be trusted".

this is normal with unlocked Bootloader.
You can extract SYSTEM.img,CUST.img,BOOT.img and flash via Fastboot
Reboot into Bootloader and flash this 3 img files with this command
fastboot flash boot BOOT.img
fastboot flash cust CUST.img
fastboot flash system SYSTEM.img
and Factory Reset
but this message at startup is normal
"Your device has been unlocked and can't be trusted"

How to reinstall stock rom!?

Hello
I unlocked my bootloader, then installed CWM, rooted then installed unofficial EMUI 4 ROM.
But I was EMUI 3.1 before...
So my Honor 6 didn't work after that and never couldn't boot the ROM
When I try to install CWM again by Multi-Tool, flashing error says that I need to check the confirmation dialog on my device but I cant't access to my device because there is no ROM :|
I installed EMUI 4 stock recovery and now what can I do for reinstall the rom -_-
Is there any way at all?

Have you tried downloading EMUI 3.0 stock ROM and using the three button method after placing it on your SD card? which is power + vol up + vol down?

In order to get back to full stock ROM follow these steps, since you already flashed recovery of a build number I don't know, do it again by following the procedure:
Download your phone's latest firmware and extract system.img, boot.img, recovery.img, cust.img from UPDATE.APP using Huawei Update Extractor tool.
Flash recovery first, using this command.
Code:
fastboot flash recovery recovery.img
Flash all other extracted files similarly firing these commands.
Code:
fastboot flash boot boot.img
fastboot flash cust cust.img
fastboot flash system system.img
After doing this put that very UPDATE.APP from which you extracted the files in dload folder of your external SDCARD.
Switch off your phone, and press Vol UP + Vol DOWN + Power button simultaneously.
Your device will now get to the full stock firmware.
Enjoy your out of the box device..!!

Hi Digicoon,
I tried your method to restore to stock ROM after successfully installing KangVip Rom.
Actually this custom rom was intended for Mate7, but beeing a simple port from Honor6Plus (as stated by the developer) I installed on my device without any problem. The only thing I noticed was that my device was no more a Honor6Plus PE-TL10, but a DUK-AL20 which I think is Mate7 model number, right?
The ROM works good but I wanted to revert it back to stock.
Anyway, I tried downloading the kitkat stock rom for my Honor6Plus (it should be PE-TL10_EMUI3.0_Android4.4_V100R001CHNC00B260.zip) , extracted the UPDATE.APP and the four files you stated above, flashed them via fastboot and then put the entire dload folder inside the root of my SD card.
The phone hangs on the boot screen and then boot loop... no way to restore it.
I reverted it back to custom rom (via nandroid backup), even tried to flash the stock recovery.img to use the "Three buttons method" but with no luck, every time it stucks on boot logo and bootloop.
Do you have any idea what could it be? Maybe a "partitions" problem, due to different model number?
Thanks in advance and Merry Christmas

Also work for rooted L04 (TWRP) back to lollipop?

Does this also work in my case?
I have a rooted L-04 with TWRP and the latest b831-software. Now that I realised GPS is not working anymore I want to go back to Lollipop.
Has anyone tried it?
Thanks for your help.

Mate 8 bricked after unroot and return to Stock B320 ?

Hi,
I was running NXT-L29C432B320 Firmware with TWRP and root on my Mate 8. Due to some display issues I have to send the device to Huawei service now. Before I do that, I wanted to unroot and go back to Stock B320 Firmware with locked Bootloader. Now the Phone doesn't boot any longer. When I start now, I see the Huawei flower for 5 seconds than the screen gets black. Here's what I' ve done:
-Unroot via SuperSu app
-Unfortunately I forgot to wipe and do factory reset
-Flash Stock Recovery from B320 Firmware via fastboot
-Tried to lock Bootloader via Fastboot, but failed
-Flashed Boot.img, System.img from B320 Stock - Device stucked in bootloop for hours
-Flashed stock B320 firmware via Huawei dload method - Bootloader gets locked but phone doesn't boot completely
I still can unlock bootloader via fastboot & unlock code and I'm able to flash files.
What can I do to get the device working again?
Thank you very much in advance for your help.

Flash all image files via fastboot and reboot and wipe and start

...I've flashed the files recovery.img, boot.img, cust.img, system.img already. How can I wipe then at start? Do I need to flash TWRP again? If I flash stock recovery with TWRP, how will I be able to wipe anything?

...fastboot doesn't allow me to wipe anything! If I enter "fastboot wipe userdata", I'll get error message "fastboot error failed (remote command not allowed)!
Is there any solution for this?

Fastboot erase cache
Fastboot reboot
Hold volume-up and power and wipe from recovery

error

Can't Boot into Stock ROM.

So recently i wanted to unroot, relock the bootloader and go back to factory condition. I flashed xposed too but i just deleted the app so idk if its still up?!
Unroot worked with supersu.
But then i wanted to relock the bootloader with the "Multi Tool 8".After relocking the bootloader I couldnt boot in my system so i Unlocked it again and booted into android 7!
Sadly i wanted to relock the bootloader so much, that i wiped /vendor and all other things except system and sd card in TWRP.
If i want to boot into system now , i cant. Either with bootloader unlocked or locked.
Only things i can do is going into fastboot mode or access eRecovery.
ADB and Fastboot Commands are working.
I tried to Rollback my device but its not working. What should I do now?
Sorry for my Bad englisch. My main Language is German.

1. Download honor 8 firmware from huawei firmware finder
2. Extract system.img, boot.img, recovery,img with huawei extractor tool
3. Unlock bootloader
4. Flash system.img, boot.img, recovery.img with fastboot with commands fastboot flash system system.img, fastboot flash boot boot.img,fastboot flash recovery recovery.img
4. Boot to recovery mode and factory reset and wait
5. Done. Now it should boot into the system.

I will Look into that tomorrow.
Do I need TWRP recovery for the factory reset? Because in Stock Recovery i cant factory reset.
So I would flash system boot and TWRP instead of original recovery?

i cant factory reset!
Flashed system, boot and recovery successful.
But when i want to factory reset it stops by 16%

Help Mate 9 MHA-L09C432B368 Stuck in Error mode 11 recovery image 2 image failed

I would like to tell you my problem, I have a Mate 9 MHA-L09C432B368.
After several attempts and letting the battery drain I could enter Fastboot mode, I have the FRP unlocked and I could unlock the bootloader again, the problem is that I can not enter either the TWRP, or to recovery mode, try flashing again the same TWRP I had installed it well but still when I want to enter after passing the Huawei logo it remains on the white screen of ERROR MODE, Func NO: 11 (recovery image) Error NO: (image Failed!) Reading other forums and looking I have been told a lot by Internet that it is necessary to make the Dload method try it but it did not work, I understand that it does not work in this model but I still try it.
I also did a flash with all the files as I found in XDA
"When you have system extracted, flash it in fastboot using fastboot flash system system.img.
Do the same with KERNEL, extract and flash to fastboot flash kernel KERNEL.IMG
(BOOT is now split into RAMDISK and KERNEL)
Recovery was split to recovery_ramdisk, recovery_vendor and recovery_vbmeta
Boot was split into ramdisk and kernel
Recovery2 (erecovery) was split into erecovery_ramdisk, erecovery_kernel, erecovery_vendor and erecovery_vbmeta
fastboot flash ramdisk ramdisk.img. Kernel flashed as fastboot flash kernel kernel.img.
Recovery ramdisk as fastboot flash recovery_ramdisk recovery_ramdisk.img "
I'm still stuck on the same screen with error 11 and 2 I made the flash of the recovery that I used when I put version 368 are two MHA_RECOVERY_NoCheck.img and MHA_RECOVERY2_NoCheck.img both give Failed using the command Fastboot flash recovery_ramdisk RECOVERY_XXXX with both the same without using the _ramdisk command is equal I'm still stuck in the same state.
Does anyone have an idea that another method I can try?
I will thank you very much.
You can flash all * .img through ADB and in this case there is a specific order to do it, check several threads but I did not get an answer and search but I could not find anything, it is worth noting that when I flash files I mentioned before all OKAY but on power up it goes back to error 11 and 2 I have been told that it is a partition problem but I could not find something to recover them, there is some method that is missing or maybe an error in the steps I am doing ? I still can not access the TWRP but I can access without problems by ADB.

Help
Hello how are you. I had the same problem, I could not access to erecovery or recovery and worse to the system. only ERROR MODE appeared on the screen, Func NO: 11 (recovery image) Error NO: (image Failed!) .. could enter fastboot mode. with PHONE Unlocked and FRP Unlock but I took it to the official technical service of my country and they told me that it had no solution. at the time of testing on my computer I was left with PHONE Relocked and FRP lock in the fastboot. I have the code of my Bootloader and the FRP even though I can not unlock it to install files to my phone. help

Hi my phone have bootloader and FRP unlocked you can fix your phone for this error mode 11 and 2 ?

I wanted to ask please if this Thread can be closed since I could solve the problem, I share the solution which I obtained through a partner of the website HTC Mania @rodrigocarlosqm to which I am immensely grateful. Thanks to your generosity I was able to recover my phone and I do not want as a paperweight, the arrangement was simple buy credits in dc phoenix, in my case download the official version oreo 368, extract the update.app file and place it in the flashing program, restart the cell phone, in case it does not do so automatic do not panic turn it off and let it turn on normally, enter the recovery stock, make a wipe, then restart and return to the recovery in this case make a wipe hard reset, restart and terminate once that happens the phone it will restart again and once this is done, the operating system will start without any inconvenience. Thank you very much to everyone who helped with the help and ideas. I could find the result and I would like to thank @rodrigocarlosqm again, he was the one who helped me recover the brick he had. For all those who are in the same situation please I hope you can solve it before any query is at your disposal. Thank you all.
