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).

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!
I have bricked my phone after Magisk install fail.
I first unlocked bootloader succesfully
then i installed twrp succesfully
then i flashed magisk using twrp - this failed and sent device to erecovery. (which won't find package)
i used twrp to wipe data, now i was able to boot, and it installed like a fresh EMUI. However, almost all apps were broken- could not download themes/camera shut down etc.
To fix this, i wanted to restore to stock and did the following: download update package for my VTR-L09 of EMUI b175 (I was on b162 before), used Huawei Update Extractor to extract files and flashed BOOT.IMG, SYSTEM.IMG and RECOVERY.IMG. This was done without error.
Now my phone won't boot at all. I am stuck at the 'your device can't be trusted' screen. I cannot go into recovery. When I connect via USB, I hear the chime in Windows but I can't seem to connect with ADB.
What to do now?? Am I hard-bricked? I hope that anyone knows how to deal with my phone bricked like this. Please help me to solve this issue.
Best of wishes.
Edit: I am able to enter forced recovery, however updates fail at 5%.
I am also able to fastboot with USB, however I am unsure what to do next.
I unbricked my phone! Many thanks to who ah way and his solution found here: https://forum.xda-developers.com/p10/how-to/guide-unbricking-p10-using-hwota-windows-t3714416
:victory:
why are you doing it when you dont understand it?
You cannot flash part of B175 firmwar eover B162 firmware.. OMG.
use the HWOTa to go back to stock and please stop playing with the device without propper knowledge
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.

Hi there guys. Please excuse me for posting this in the QA thread but because I am a new member it wouldn't let me post in the recovery section. I joined XDA just to get some help with my Huawei P9
So I have a Huawei P9 (EVA-L19) and I tried to load a custom rom onto my phone. I was going to load resurrection remix 6 onto my phone but did not get that far.
I got as far as flashing TWRP recovery onto my phone. Once I flashed TWRP recovery I still could not get into TWRP 3.1.1 instead I kept entering eRecovery. So I flashed Recovery2 with TWRP and now my phone is in a boot loop. If I let the phone battery drain completely I can boot the phone. But if I shut down or reboot the phone for any reason while there is power in the battery the phone gets stuck in a boot loop. My Bootloader is unlocked but I can't get the phone into fastboot mode. Even with Volume- and Power key and USB. It just goes straight to "phone can't be trusted page" and then boot loops. Is there a way to fix my phone when I let it run completely flat and then log back into EMUI? I tried factory refresh but it just got stuck on bootloop.
So to summarize.
*My phone gets stuck on a boot loop on all reboot/power on scenarios EXCEPT when starting from a completely drained battery.
*Cannot access fastboot.
*Unlocked bootloader
*Not Rooted
*Rebooting phone gets it stuck in a boot loop.
*How to fix phone either back to EMUI or RR6.0
I would wish to either just get my phone working again on EMUI as a last resort. But ultimately I would like to finish putting on RR6.0 because I was unhappy to hear P9 wouldn't get Oreo updates.

RROS 6.0 must go on Android Oreo / EMUI 8.
You first had to rebrand your phone by HWOTA7 to Chinese Oreo AL10 c00 b535 or b528.
Were you rebrabding and hence needed TWRP, or you were trying to flash RROS 6 (for Oreo) on L19 (on Nougat or even MM) together with TWRP 3.1.1 for Nougat?
Please answer precisely:
- What was the full name and number of your stock build you were starting from (like EVA-L19c432b504 or so, not just "P9 L19")
- Have you already flashed (by Fastboot) RROS 6.0 or your first step was trying to install this TWRP?
- Where did you pick up that TWRP 3.1.1.1?
If you picked directly from TWRP site then this TWRP might not work even for Nougat (EMUI 5.x)
- If you picked proper TWRP from XDA threads, then there is always an important detail described:
Immediately upon flashing TWRP, you must boot into TWRP - otherwise you loose TWRP as if it was never flashed.
You must:
- press and keep pressing Vol+
- type in: fastboot reboot, Enter
- IMMEDIATELY at the moment when phone turns off, disconnect USB
- keep pressing Vol+ until you see it boots to TWRP.
Reasons that you were not able to install TWRP might be:
- wrong TWRP
- you did not follow this 'trick'
- you were flashing proper TWRP for Nougat but your L19 was on MM (EMUI 4.x), or you were flashing it once you already rebranded to Chinese AL10 Oreo, or upon you flashed RROS 6....
There are various possibilities, please precisely describe - it's not why TWRP did not flash but why (after this possible mess) your phone does not boot and how to fix it now

No I did not get as far as flashing RR6.
I downloaded TWRP 3.1.1 openkiren for Eva from TWRP's download page.
I only got as far as attempting to flash TWRP no custom rom was flashed yet.
I could of sworn I HAD EVA-L19C185B405 when I started this process.
However I now have EVA-L19C185B403. Not sure if my phone rolled back somehow. If I try search for updates it says the phone is up to date.
My L19 is on Nougat. It's on EMUI 5.0.3 Android 7.0
I did not rename my phone with any Chinese P9 builds or any tricks like that. Didn't even know you had to do that.
My phone still works provided I don't reboot it. And if I do reboot it, it gets stuck on the bootscreen until it drains completely. Then I plug it in to power and it boots successfully again.

For EMUI 5.x you must use TWRP 3.1.1 from XDA (adapted for Huawei Nougat and its encryption), best the latest build eg from post #1
https://forum.xda-developers.com/p9/development/rom-huawei-p9-magicrainbow-v4-t3759292
and you must flash it with the trick at rebooting as described in previous answer.
Your TWRP you flashed to Recovery2 (?) is likely not even good for Huawei N (but probably for MM).
You must fix your Recovery2 by flashing back the proper stock Recovery2.
You need to download update.zip corresponding to your c185 build by Firmware Finder (find XDA thread about, there is also PC version), unzip and put update.app to Huawei Update Extractor (find also XDA thread about) to extract your stock Recovery2.
Once you repair, please carefully read HWOTA7 instructions how to rebrand (and upgrade to Chinese Oreo - this is a must if you would like to play with OpenKirin Oreo ROMs, they can not be installed to L19 Nugat builds) - and this required rebranding is far more than 'renaming'

For the other two I gave you links.
You will really need to spend your time to read the guides
Ok how do I reflash the recovery2 if I cant get into fastboot mode on my phone. Can I do it from inside EMUI?
There are two ways to boot to Fastboot
1) Power off, connect by USB to PC, press and keep pressing Vol-, press Pow
2) From Android, enable Dev options and ADB, connect by USB and execute: adb reboot-bootloader
You cannot by either way?
For Oreo but also reported for some newest Nougat builds, eRecovery gives you an option to reinstall current firmware.
But if you cannot boot to eRecovery, because you attempted to flash TWRP over Recovery2...
Actually, try to boot to eRecovery: power off, connect by USB to charger, press and keep pressing Vol+, press Pow.
If it boots to TWRP (instead of to eRecovery) you can try:
-flash stock eRecovery to recovery2
- flash (proper, from XDA, link was above) TWRP to recovery
There are other methods: HuRUpdater, HWOTA7, HWOTA as improved variations of nonCheckRecovery, but
- first two require Fastboot to start (they will flash TWRP)
- last two require already installed TWRP
(apparently not applicable to your brick)
In HiSuite, for Oreo (maybe also Nougat, I don't know if it depends on Huawei firmware or newest HiSuite version on the PC), there is an option to upgrade/downgrade.
You can try if you could (re)install some stock firmware that way but I never played with.
For eRecovery and HiSuite (if you would be able to do) it is unclear if (re)installation of stock firmware will succeed (or even further brick your phone - don't know if anybody else had such a brick as yours and tried them).
If none as above, you may try DC Phoenix (15 Euros credit?):
https://www.dc-unlocker.com/DC-Phoenix-flash-repair-tutorial
I didn't need it but search on XDA, from time to time people report (usually in not highly exposed threads) that they were able to unbrick various Huawei phones (when no other methods worked or they were too lazy to investigate and experiment) - but their on-line instructions are not very detailed and they are not very friendly if contacted for help
Got official notification and have installed Pie (9.0.1.163) on my VTR-L09C432 P10.
Downloaded the Full OTA (9.0.1.163), extracted the RECOVERY_RAMDIS.img, patched with Magisk 7.1.1 and flashed using fastboot to the recovery_ramdisk partition. When rebooted with Vol+ have root. Played around with Pie and have decided to revert back to Oreo.
HiSuite (v9.0.3.300_OVE) did offer me rollback to 8.0.0.365. So I have decided to pursue this option. The firmware download went OK (100%), the programing went OK (100%) and the phone rebooted, as said the popup, but ... it was still on Pie as before.
Decided to try to "upgrade" via eRecovery. It wasn't able to determine and download any package. So I tried factory reset. No error, but it seems to do nothing. The phone rebooted and the situation is: Pie works, Magisk reports root 18.1 and root apps work.
From this moment I am unable to enter fastboot. The phone just boots normally with Magisk root. As I have just written eRecovery is present but is useless (can't download an upgrade package and can'r factory reset).
Advice?
Should I try writing from a term using dd the extracted RECOVERY_RANDISK.img and ERECOVERY_RAMDISK.img ? This way will loose root (Magisk) but don't know if it "resolve" access to fastboot and "fix" eRecovery.
EDIT:
No reply so decided to go ahead with what I thought was happening. I didn't know that a firmware upgrade (or downgrade) needs recovery to complete. I thought erecovery was the key.
So when I used HiSuite to rollback to Oreo what happened was it downloaded the Oreo firmware, uploaded it to the phone, prepared for a firmware flash and did a reboot. The firmware downgrade was supposed to happen in recovery but since the recovery code was changed by Magisk the flashing was never happening.
The same when from erecovery I tried to do a factory reset. Seems that erecovery just prepares things but recovery code does the actual reset. And once again I was observing that nothing was happening. The phone was simply root booting exactly as the Magisk code is supposed to do.
So I just flashed (from a term) the original recovery_ramdisk.img. After reboot got the factory reset welcome screen.
Of course got back fastboot.
Hope this can be of of help someone is a similar situation
Dude can you please guide us how to actually use DD command.
edit: I did this a different way. much easier & safer for less experienced users.
1. Open magisk manager. At the bottom of the first screen there is a button "UNINSTALL". Press uninstall & click "restore images".
2. Magisk will remove itself and restore your original boot image. Worked for me
