Hello Guys,
I am new to Huawei so I am just gathering information on manually updating stock rom. From what I have search through so far, the easiest and safest way is to download the stock rom, copy the update.app file to the dload folder on your sdcard and then reboot the phone while holding down vol up + vol down +power.
Now what I need clarification on is what are the prerequisite before doing this. So I have already unlocked the bootloader, have TWRP recovery and rooted. Reading through the forum, some threads states you need stock recovery while others say it works even with TWRP recovery. Some say you need to un-root first while others say you dont. Is there anyone here who can clarify what needs to be done before flashing the stock rom?
Just to paint a picture on what I am planning on doing, I currently have a C34 (Optus, Australia) and I want to debrand it by flashing C636 (Asia Pacific) and I think flashing via the sdcard is the simpliest and safest way.

Hi everyone,
I am looking for the way to start this phone directly on the fastboot mode as it is softbricked and it doesn't recognise anything (i can't go on recovery, no matter which one) after I flash a stupid update.app of 500 mb
I think I have to flash system.img boot.img and recovery.img
Thanks in advance, it don't go on the fastboot by himself like he did before, after i flashed twrp
Edit: Found, vol - & power while wired to the computer. Gonna see why i can't access even the stock recovery
Press and hold power and vol(-) buttons ... long time. Of course first remember to connecting device to PC by USB. [emoji14]
Hundreds times...it was described on this forum. [emoji26]

New question, I installed the B121 full stock, rom, kernel, everything like when i baught him first day, except of my unlocked BL.
Now, the stock recovery can't install ANY update.app it always write "FAIL" without getting any %, it just fail as it start. I can't find the way to resolve this.
And I got many questions,
Can the recovery of B121 install the B609 ROM?
Can the B609 install B121? I mean how is the retrocompatibility working with this device/recovery?
In a update.app you got many files, boot.img, system.img but also 3rdmodem.img hifi.img modem.img...
What are those files? Why am I not allowed to flash them? Why I could start my device without flashing every files? They aren't necessary? Or they are generated by the "base rom" constitued of boot/system/cust/recovery/userdata?
Also, do I need to be rooted or something to boot on twrp? I can't boot on any other recovery except from B121, even if i extract one from update.app 609...
Thanks in advance
Guys , I have to sell my phone, so, I decided to do all the necessary to have it stock..
So, the question is, how can I do this? I need the phone like when I bought it
You can do most of this via SRK Tool. If you can't relock bootloader then you can flash your stock update.app via stock recovery and that will relock your bootloader and get rid of root.
Please don't follow this for when you have Nougat beta installed though.
I currently have TWRP recovery.. How can I put stock recovery?
Is better to put 1st the rom and for 2nd the recovery or contrary?
Anyway thanks for answering me!
1. Backup (as always)
2. Flash stock recovery with flashify for example
https://www.androidfilehost.com/?fid=529152257862669572
3. Flash stock Rom b182 with dload-method
http://download-c.huawei.com/download/downloadCenter?downloadId=91783&version=358257&siteCode=de
Now your Bootloader is relocked and everything is stock again (I hope so)
Hi there, I am currently running B383 on my P9, and really want to root it. However when I do, will I still be able to get future updates to the software? Do I need to unroot and lock bootloader first?
Also when the bootloader is unlocked, a message is displayed at boot about your phone being unsecured and non-trustworthy, is it possible to remove this message? (I used to have a moto g with an unlocked bootloader, and I flashed some file to remove the warning).
Thanks
I don't think there is a way to remove that message every time the phone is turned on. Mine does that too as I've unlocked the bootloader.
Did you unlock the bootloader yet? Because when you need to unlock it, the phone will basically be factory reset when bootloader is switched from locked to unlock (vice-versa).
And for OTA updates the best way is to do it manually, downloading the MV-PV file via Huawei Firmware finder (Full PV file which contains two files update.zip and hweu..zip, update.zip (system firmware) is flashed first then hweu.zip (The system apps).
You will need a custom recovery. The one you will need to use is TWRP (This one specifically - twrp-3.1.1-0-eva.img) to flash OTA's via custom recovery (To repeat you flash update.zip first then hweu.zip) You can ignore the errors if it prints any while flashing the OTA files as I did the same and it worked fine no problem.
When you want to root your phone, make sure to flash 'SuperSU-v.2.82-EMUI5-SELEnforcing.zip' via TWRP recovery to root your phone.
For the other questions, you do not need to unroot the phone to install the OTA updates. The phone will just unroot itself when the OTA update is flashed onto phone. You simply just need to re-root it again by re flashing the SuperSU zip as mentioned above.
When you need to boot the custom TWRP recovery you need to turn the phone off and hold power + volume up until Huawei Logo / text is displayed you must release both keys immediately after 0.5-1 second which is a short time frame to get the phone to boot to custom recovery or else it will boot the Huawei eRecovery instead.

Thanks for the quality answer, I have no doubts anymore!
Hello friends, recently I saw a tutorial on YouTube how to remove the bootloader unlocking notice in Huawei, as a software update arrived for my EVA L09, I wanted to do everything from factory without root or recoverys to install it via ote. So I removed the twrp by the huawei recovery and followed all the steps that the man made and reset the development settings, then I worked in the ADB to re-lock the bootloader, after finishing the processes, my phone was restarted and I'm stuck in the bootloader logo of Huawei, I never step out of there. I wanted to enter the fastbot mode and I can not because it seems to be deleted, I do not know what happens because it does not enter the fastboot mode and only reboots again, nor do I have access to the normal recovery. I tried to use the volume method up + down and power button using the UPDATE.APP but there are no such methods, the phone is apparently clean. it only stays in the logo.
I took him to the technician and he told me to communicate to the support of Huawei because he did not know what to do, I would appreciate too much to help me please, because nowhere do I find something and you are the maximum.
thankfully
Updated thread title and moved to P9 Q&A. Hope this gets you the answers you're looking for.
There are good and proven tutorials here on XDA (XDA has its own search), not sure what did you find and follw from YouTube ( was it for proper cust, proper case of going back from root or custom ROM and which one to stock and which stock build, etc)
To unbrick, you have three options:

- free method but AFAIK it requires Fastboot working

Hello friend, thank you for answering, what I did was the following https://www.youtube.com/watch?v=s9BZuywrRAw I had the original rom of android 7 and I got the update through the B398 ota but I had root and twrp, I wanted to leave everything in the factory by removing the twrp and replacing it with the huawei recovery and removing the root. When it was restarted, it never came back and I do not understand why I do not have a fastboot or recovery mode.
Thank you
It is not enough to say EVA-L09 and b398.
You must know what was exactly your original stock ROM (before you rooted), like was it EVA-L09c432b397 or what.
Then, there is very simple method to go back to the stock ROM you started from, say to c432b397, wherefrom you would then be able to accept OTA to b398...
It's all about flashing the correct HWOTA package through TWRP, and you would be back to your unrooted stock and back to your stock recovery:
https://forum.xda-developers.com/showpost.php?p=74913874&postcount=3
Unfortunately, now after the YouTube, you have no Androud, no TWRP, no fastboot...
Btw, unlocked Bootloader does not prevent OTA updates. It was only neederd to unroot and then to go back to stock recovery - both you simply get just by flashing the right HWOTA package.
Alternatively, you could have to unroot (SuperSU has its own option to remove root, for Magisk there is a ZIP package to uninstall Magisk), and to flash the original stock recovery - and you would be clean to accept OTA (although with Bootloader still unlocked).
Hello everyone!
I've got an P20pro rooted with stock Emui (check the screenshot attached). I come from LOS 15.1 but I preferred to go back to the stock, even to get OTA updates. And OTA is arrived but, if I try to update from the Emui, of course, when go to recovery it is go to TWRP and OTA fails.
Is first time I want to flash stock recovery EMUI and I don't know how to do that. I suppose with Fastboot but I can't find a guide, and I'm bit noob... so I ask help from you
In addition to the guide I would also need to get the right Emui recovery version for my device (I don't know if every model need a specific recovery), and I would like to know if when I do flash Emui stock recovery I will loose the root and, I think, the TWRP.
Thanks guys and be patient if my questions may seem silly!
I also need help with this. I have clt-l29 9.0.0.163(c432E5r1P9). Do I need the stock recovery, stock erecovery and stock rom to get the bootloader relocked(locked) and FRP locked again?
If so, how do I do it and where can I get the files that I need?
Hope someone can help with anything they have.
Best option would be use hisuite on pc to go back to full version, power off phone and hold Vol down as connect cable, this should put you in fast boot, repair phone from hisuite, this will flash you back to latest official Fw for your model, you will lose your data.
