P9 eva dl00c17b377 - Huawei P9 Questions & Answers

Hi, I've been trying to find a way to root this P9 version the whole day. Somehow I am stuck now. Bootloader is unlocked and I managed to install twrp. I can also install the patched SuperSU but when I reboot it keeps on looping and boots into eRecovery after a couple of times. Already tried a couple of SuperSUs but nothing works. Reason for the Root is that I want to debrand the phone and flash european firmware.
Is it eventually possible to roll back to marshmallow to get it rootet? Any advice what I could try?

Impossible to install TWRP on Nougat rom

I have a big problem to install TWRP on my P9 EVA-L09C432B378..after unlocked the bootloader; activate debugging mode, I use SRKToolHuawei-Lod-Chong-V2.0-20161002 with success but i want to reboot in recovery, it's Huawei stock recovery, I try another method with command and ADB and TWRP 3.0.2.0 with success, but got same issue, no TWRP...So I decide to revert back to 6.0 and update again to B378 version and try again both methods but still same issue.....is there a solution????
thank's
EDIT : FINALLY, I answer myself because I find THIS and it worked on 1st try, so now I'm rooted but I can't still install TWRP....
try again with rooted device bit still the same...

Help me unbrick my P9 and get back to stock (marshmellow android 6.0 FW) please

So i was wanting to upgrade my P9 EVA-L09 phone to Nougat 7.0 i followed guides on here to unlock the bootloader, install TWRP and root the device which went fine. I then got the 2 Nougat FW files from here http://www.stechguide.com/download-huawei-p9-b380-nougat-update-2/ and used TWRP to install the first file 'update.zip' which flashed fine but i didnt realise i needed to also flash the 'update_data_full_EVA-L09_ee_gb.zip' file before rebooting the phone, so after the first file was flash i rebooted the phone from TRWP the phone booted fine but i notice some apps etc were missing. So i tried to boot the phone into TWRP again to flash the 'update_data_full_EVA-L09_ee_gb.zip' file but im was unable to get TWRP to load and all it would load was the Huawei eRecovery app.
So i then decied to try and get back to stock FW buy getting the Marshmellow FW (android 6.0) and using the Volume up + down and power method to force the FW flash, that said it flash successfully but now im stuck on a 'this system is rebooting' loop screen.
Fastboot screen is still saying the phone is 'Unlocked' but FRP is 'Locked'. What do i need to do to get this phone working again please?, is there a recovery FW i can force flash via the Volume Up + Down + Power button method??

P10 Bricked after bad TWRP, need help

Hi everyone.
I have a VTR-L09C119 that got bricked after formatting the data partition in TWRP. When I try flashing a debranded FULL-OTA rom I get into a bootloop, and the erecovery won't work (Online recovery won't start, Factory Reset goes into bootloop). And I can't get into TWRP anymore even after flashing it.
I tried putting the VTR-L09C432, VTR-L29C432 and the VTR-L09C605 with the HUAWEI Multi Tool with the Unbrick option, which didn't work.
Any idea how to get out of that mess?
EDIT: Ok I was able to get into TWRP thanks to THIS GUIDE. I'll try a debrand and report back.
I was able to rebrand to VTR-L29C432, the update for VTR-L09C119 doesn't seem available so I don't think I'll be able to get back into my stock rom. For those in the same boat, don't forget to unplug your phone when you want to get into TWRP, that's why I wasn't able to get back into it.

Please help unbrick my phone

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

Huawei p9 EVA-L09 No fastboot/recovery access.

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).
