You said you successfully downgraded?
Then you didn't need HiSuite (and TWRP) - just WiFi and SIM card to start receiving OTA back to Nougat
And no need to open new thread each time
What was exactly full model/cust/build name from Settings/About of your running system (you didn't provide it in the first thread before downgrade, neither now?!
Flashing TWRP, downgrading/upgrading and now unbricking (?) depend on that - did you downgrade and had it working EVA-L09c432b182 or what?
And TWRP for MM is different than for N

Android 6 doesn't mean anything for your question why it doesn't upgrade to Android 7.
And again, you are not answering what is the full build name (incl cust) and number of your build as in Settings About - but if you don't mind about reading it...
If you are sitting on eg c900, you will never ever receive any upgrade.
Also, for OTA you must have WiFi but also a valid SIM card.

My bootloader is unlocked, but I'm sure it will work with locked bootloader.
You need to unlock your bootloader to downgrade to the b052, also for use fastboot, but it's a lower price to can have marshmallow.
And of course you can relock it after,like this your warranty was not void.
I had the 5.1.1 beta b009 and I just installed 6.0 b525 with local update, everything worked fine

Can you help me please??
Can you please help me out? I cannot seem to get an unlock code from Huawei, it says something about having the phone registered on the Huawei Cloud for 14 days before they would give me an unlock code (my Chinese is very broken, so I do not know whether I translated that right). My phone is the P9+ VIE-L29. Thanks!

hello
1st you need to know the version of your phone :
boot into TWRP -> Advanced -> File Manager -> /dev/block/platform/hi_mci.0/by-name -> copy the "oeminfo" file to extrenal SD then To your PC
open The file with an HexEditor program -> Go to offset 4D200 : you must find the version of your phone (VIE-L??C???B???)

if the FRP is locked , you can not flash img, to unlock it go settings -> About phone -> press Build number 7 times to activate Devloper options. Then go Settings -> Developer options -> activate "Enable OEM unlock"
To install a clean Nougat version, you must run an official M ROM on your phone then use FirmwareFinder (proxy methode)

Impossible to put Huawei P9 in stock rom

Hi everybody
Wishing to sell my Huawei P9 I wanted to return it as it came out of the factory but impossible.
It has the bootloader unblock, FRP lock at one time it was unlock and since I tried to make an update it went into lock and the TWRP recovery of installed.
It is under 5.0.1 and android 7 and the number of buils is EVA-L09C530B284.
I tried the 3 methods to install an original ROM of my operator but nothing to do that does not.
- The DLOAD method: it restarts in the recovery twrp there are steps that are done and then it failed all in 2 minutes.
- The forced update method: that's 5% and installation failed.
- With hi suite: everything is going well and said that such is up to date and restart nothing I'm still in the old versions.
I did the 3 methods with the unrooted phone.
I feel that it is the recovery twrp that blocks the installation.
How to install the original recovery and install the official updates?
Thank you in advance for your assistance.

Sorry, I don't understand your question.
For both HWOTA (first link) or HWOTA7 (second link) you need to unlock Bootloader first - but you wrote above that previously you had unlocked Bootl8ader, hence you can use the same Bootloader code - it is bound to your eevice.
Asvdescribed in HWOTA instructions, installation of some stock ROMs will automatically relock your Bootloader (it-sa flag in the update.zip, out of your control) - hut you can always unlock it again.
ok it's good I just made an update and everything is back in order it is as if he came out of the box
thank you very much

For the EMUI 8 to 9 tool you will need root. You can do it from TWRP if you wanted to.
But you will need an unlocked bootloader at least, else you won't be able to install it.
No service = its not a service firmware, as most are on androidhost.ru.
Everything works fine. I just flashed it.

It says "no service" because it's not a DLOAD firmware.

It won't with the EMUI8 tool as it is now.
I will edit the EMUI9 tool and upload it, it will only require unlocked bootloader.
Edit: You can just use the EMUI9 tool as is, it's using Oreo TWRP and Oreo NoCheck.
As I am sure that EMUI 9 comes with new bootloader, is it possible to flash it without flashing xloader? As the Custom treble rom I want to use do not work on 9.0 vendor, so I could downgrade back.
Or uses the EMUI9 the 02xloader? If 02 then I can upgrade it to try it out!
Hopefully the update doesnt come x years laters for the ones on the official beta lol, anyway have fun guys

Unlock phone, flash twrp by pretoriano80, flash Magisk zip in twrp.
Alternatively: unlock phone, patch ramdisk in Magisk Manager, flash patched ramdisk in fastboot.
Would this method work for upgrading BLA-L29c636 b145 to BLA-L29C636E2R1P13B159 (9.0.0.159)
Is there any chance of getting a working TWRP/root on this version?
Great news. I've just installed it without problems. Is there any safe way to unroot and relock bootloader?

Apparently the root developers, amongst others John Wu (Magisk), are working to get a simple way to root EMUI 9.0.
The root has already been confirmed to be working on the Huawei Mate 10 Pro and more devices should join the party sooner or later.

All versions of EMUI10 that I've tested so far, force locks bootloader. So don't install if you don't want to get locked. I guess if you have beta access approved you can downgrade back to 9.1 using HiSuite.
I have to downgrade using testpoint
Fastboot will still say you're unlocked but the command fastboot oem lock-state info says it's locked. Downgrading back to 9.1 will give back the unlock status, apparently. I guess they just add something to lock even if you're technically still unlocked. And the command to unlock through fastboot is removed so no way to unlock it again. I hope it's just locking for the beta.

Like @ante0 said in the previous post, we already have the links for the updates, but so far all of them will trigger the bootloader lock, so unless you don't care about it, you should refrain from flashing EMUI10.
If the final release won't change this behavior, then probably Huawei has decided to lock the bootloader for good.

Downgrade to EMUI 8?
Well, if you do like me you have to as I have to flash board when BL is locked.
If you mean to keep unlock it won't work. Update from Oreo to Q directly will cause problems, it did for me when going Oreo to 9.1 anyway, and system update actually forces you to flash the latest stable 9.0 (9.0.0.197) to update to 9.1.0.300 then to 9.1.0.306.
And it's not like it's using a function to lock BL like they do when you flash a dload firmware. It's probably still unlocked but something changes it to locked. Iirc you could unlock using TP before, but now it refuses as USERLOCK is changed to unlock as well when you use testpoint, so it will just say "Phone is already unlocked", before it only changed FBLOCK to unlock.
But we will see what happens

Installing with no-check recovery should work just fine, but you should also flash the new CUST and Preload.
If you really want to flash it, i can send you the link with the latest build (B140), but like i said, it will lock your bootloader.

You can use the 3 files tool (skip the rooting part, of course) from here -> https://forum.xda-developers.com/mate-10/how-to/tool-emui-9-0-to-9-1-upgrade-tool-t3949867 <- and replace the nocheck.img with the one from here (tge no verification version) - > https://forum.xda-developers.com/mate-10/development/recovery-nocheck-pie-t3950037
Make sure that the downloaded firmwares are not corrupt, otherwise the installation may fail, because the no-check recovery will skip the integrity check.
I will send you the update files in PM.

It doesn't really matter. When you flash it you won't be able to flash any newer ones as you won't be unlocked anymore, and can't unlock again either without downgrading back to 9.1.
I would wait until official to see if forced locking remains or not.
