As asked in the title, can I update a rooted Huawei P9 with custom recovery to Nougat update?
And if not, what should I do in order to update? Remove root and custom recovery? Factory reset?
Thanks in advance
What the firmware version do you have ??
You can update the phone, but changind the firmware will mean that you'll lost the root.
You can update it, then you can root the phone again ....
EMUI 4.1.1
I also have TWRP custom recovery.. Would that make it riskier to update?
And how should I update? Wait for update to be available through phone or other methods? And what would be the other (easy) methods if I decide not to wait for it to be available through the settings on the phone?
If possible and not a bother, could you link another thread or a guide for this, please?
Thanks for all the help!
What build number do you have? It should be something like L09C432B383.
You can update to Nougat using TWRP but you will lose root and TWRP Recovery will go back to stock recovery. Just download the appropriate Nougat firmware that matches your Cust number (Eg, C900, C432 etc).
You can flash TWRP Recovery again and root your phone after the update.
Note: Nougat supersu.zip file is different from Marshmallows.
Build Number: L09C606B150
Ok, so should I do it directly through the phone? Or Pc?
I found an update to Nougat with the Build Number: C432B322. Should I use this one to update? And should I flash through TWRP? If yes, how should I do it?
Sorry for all the questions, I've never bricked a phone and not ready to do it now...

No you have to find a firmware that matches your cust (C606). If you flash this C432B322 you will brick your phone.

Thanks! I fortunately waited for the answer before updating hahaha
And I searched for an update with c606 and didn't find one.. how should I proceed with that?
If you really want to get to Nougat and not wait for build releases for your cust C606 then you will need to debrand your phone to C432 cust following this guide:
https://forum.xda-developers.com/p9/how-to/guide-debranding-to-c432-updating-to-t3551523
And do keep in mind doing incremental updates instead of jumps ahead of a build is better to do to avoid compatibility issues from build to build.

First you must flash stock recovery. You can extract from another full rom 7.0
Second you must have downgrade pack for your region and mobile operator.
Next you must have full rom 6.0 for your region.
You must have all file because you don't want debrand your firmware
Thanks, actually if i want debrand my phone whats the diference? Because I think I don't care...
Also, where can i find all of these files you write about?
I'm really lost with all firmware versions ... Does it matter if my version is EVA L09 C33B363 and i flash stock recovery from another version??
Also, my bootloader is locked, do I have to relock it? Does it even possible??

If you have locked you must unlock again. All file you can take from forum. Debrand it's unlock warranty and sometime you loose your guarantee. But what region you from

Here you have how debrand
https://forum.xda-developers.com/p9/how-to/guide-debranding-to-c432-updating-to-t3551523
If you debrand you can then flash stock recovery flash b300 and then b136 and do it wipe in stock recovery.
When you want debrand first you see your cust be c900 and then you must flash stock recovery do it wipe system/data and cache
If you do it your cust change to c432 and then must check your region using dial pad
*#*#2846579#*#* then push 3 and 4
If you see your vendor: hw and country: Europe
You can downgrade to b300 and then to b182
You lose your theme and you see ugly icon then do it wipe system/data and cache in stock recovery
After this you have update to b383 then b386 next to b391 and final to b393 or b394
I have b393

Hi I have a xt1803 G5S Plus, retgb and have recently unlocked bootloader and rooted my stock ROM which is NPSS26.116-26-14.
I have noticed there are higher version numbers available like NPS26.116-61. How do I go about having the latest stock ROM with twrp and root access? I'm guessing the stock ROMs are not flashable via twrp. Would I have to flash the latest stock ROM via ADB like it explained here
https://forum.xda-developers.com/mo...lash-official-firmware-moto-g5s-plus-t3681018
and then unlock bootloader again, flash twrp etc like starting from scratch?
I honestly would not recommend flashing NPS26.116-61 to your device. Despite the version number being higher, that firmware is actually for a different region (I think NPS26.116-61 series firmwares are for India and Indonesia, whereas the NPS26.116-26 series is for EU/UK). If you flash that, you may find yourself ineligible for OTA updates at all, since your build does not match that expected by the stock OTA servers, and if there are incompatibilities between the firmwares - since they are for different regions - you may have issues with IMEI/SIM access.
If you wanted to update though, you'd have to follow the steps in that guide. Though I don't have a G5S Plus, you would have to remove TWRP/root through a stock ROM flash (no need to re-lock bootloader), then update via OTA, then flash TWRP and re-root. If you can find a stock ROM with the same firmware build as you have now, you may be able to preserve your data by omitting the 'fastboot erase userdata' command from the stock ROM flash commands, but I would recommend you have a backup (e.g. TWRP backup) before flashing anything.
There's a copy of the NPSS26.116-26-18 stock ROM (June 2018 stock ROM) here, flash at your own risk: https://forum.xda-developers.com/showpost.php?p=77025728&postcount=507 This build was released as an OTA update to retgb devices as reported here: https://www.reddit.com/r/MotoG/comments/8w0c0c/june_patch_now_available_on_retgb/
Hello I'm the proud owner of a VTR-L09 P10 with the oreo based VTR-L09 8.0.0.364(c530) firmware and an unlocked bootloader. I have tried many tutos across the internet but I still can't downgrade it to nougat in order for rebranding to VTR-29.
Can someone with matching conf or a close one who has succeeded in rebranding can help me with a working tuto.
Thanks in advance and....
HAPPY NEW YEAR !!!!
First, you twist nougat and Oreo. Your phone is on Oreo and you wanted to downgrade to Nougat.
I don't know, why the downgrade didn't work for you, but maybe now it does with the correct understanding of versions (nougat is the older one).
If you're a bit experiment friendly, you can try something for me - but I really can't guarantee you that this will work without brick!
You need an SD card for this, don't try it without!
- Download your desired firmware from Firmware Finder. I recommend 8.0.0.382 for L29-C432, which I installed on my rebranded P10 yesterday.
Here are the links:

http://update.hicloud.com:8180/TDS/...86/f1/full/public/update_data_full_public.zip
- Download my oeminfo file and put it on SD.
- Download and flash this TWRP. It will ask you for a password at boot, type your phone PIN.
- Backup your oeminfo with TWRP on SD AND internal memory, just to be sure.
- Now flash my oeminfo file with TWRP via Install/Use Image.
- Go to my guide and follow now Tutorial #2, Oreo to Oreo, exactly. You can use the TWRP version you already installed, but everything has to be like in the tutorial.
It should work, but, as I mentioned above, I can't guarantee it.
The worst thing which can happen is that you brick your firmware. For this, you should be able to reinstall an L09 firmware after restoring your oeminfo file via eRecovery.
But I think the recovery will stop installing L29 if it didn't work with the oemfile - if so, you just need to restore the oeminfo backup.
Don't boot into your L09 firmware with L29 oeminfo!

There are Open Kirin Treble Oreo ROMs (RR, LOS) for Huawei/Honor phones:
https://openkirin.net/user_guide/openkirin-rom-installation-instructions/
Installation instructions require:
1) OK Oreo ROMs can only be installed over Huawei stock Oreo (not over stock Nougat)
2) OK ROM must be flashed by Fastboot, not from TWRP (btw, TWRP for Huawei Oreo is different than TWRP for Nougat because of different partitions names, sizes, etc)
There is also XDA thread about Open Kirin Treble ROMs (on P9):
https://forum.xda-developers.com/p9/development/roms-openkirin-aosp-collection-t3828806
and for (1), there is a thread describing how to rebrand P9 L09/L19 to AL10c00 and update to Oreo (b540):

First, go back to stocl Nougat, and please read again my previous answer - I gave you link for HWOTA7 method for rebranding from stock L09/L19 to AL10 and then upgrading toAL10c00 b540 Oreo
If you don't like unlocked FRP, then go back to stock Nougat and re-lock Bootliader (and then lock FRP back).
But as long as you do rooting, installing custom ROMs, or rebranding to that AL10, you must have unlocked Bootloader and for unlocked Bootliader you must have also unlocked FRP

(Re)installing/OTA updating some stock firmwares lock back both OEM/FRP and Bootloader, but it depends on the firmware itself (Huawei who prepare them).
If you already installed latest firmware for your cust by eRecovery, you can only try to do Factory reset from stock Recovery or eRecovery
Otherwise, rolling back to Marshmallow (and after that updating again to Nougat) shoulf fix the problem with disabled OEM unlock option (I had it twice but in the opposite way, OEM was locked but its option was disabled)
However, having unlocked FRP is not a big trouble. You can still open Bootloader and root/flash, etc - problem would be if OEM option was disabled but locked - then you could not unlock Bootloader and flash anything from Fastboot
With FRP=Factory Reset Protection unlocked you (only) have:
- 'annoying' note that phone is not secure while booting
- ability to start Factory reset from Recovery and eRecovery (with licked FRP, Factory reset is only allowed once you login to the System, from Settings or Project menu)
- ability to unlock Bootloader and flash things
So, what if i wanna install Android 7 custom rom? How can i do it? Can i do it with TWRP'S special Open Kirin Edition directly from Stock Rom?
Can i upgrade my phone to Android 8 after i install Android 7 custom rom first or i have to do it with Rebrand / Update Tool first?
Because rebrand / update tool (or SRK Tool i am not sure) look so complicated and i am afraid to make hardbricked my phone... (i backed up my phone with HiSuite but i am not sure can i recover my phone with it if i unbrick my phone?)
I am using EVA-L09C464B389 rom now.... On the other hand, i cant be sure which AL10 (Oreo) rom is right for me, because when i search in russian page you offered, there is more than one alternative...
I hope i can explain what i mean with my poor English...

How do you install Noigat custom ROM? - decide which custom ROM you want to use and then find its documentation and learn there how it must be installed.
And/or, find the forum/thread about that custom ROM and read the OP posts, and ask your questions there
Which AL10 ROM you want to install...bxs on Russian forum there are alternatives? - If you want to follow XDA guide, then READ it and you will find answer there.
But if you want to follow Russian guide, then register to the Russian forum and ask your questions there
Good night and good by, I'm disconnecting from this thread and will no more read/answer - good luck
Dear @zgfg
First of all thanks for all your answers, but I am not use Russian forum same time with here. The page you advice me (in xda), and the application in there, using Russian webpage to dl stock roms... Sorry if I make you angry...
