Guys, I was on C185 and tried to get to C636 but didn't do the repack, so now I'm stuck with System 8.0.0.046 (0AGDZ) some of Huawei stuff not working and unable to get back to C185 or C636, anybody has a solution for this? I can flash TWRP, can use Stock Recovery but everything that I do ends in that System 8.0.0.046 and no C636 or C185.

I have tried to rebrand and failed downgrade (at 6%) and now my model is VTR-29 but build is System 8.0.0.046(OADH). How can I fix this and have a correct build? Thanks.
[Huawei Mate 9 Guides, News, & Discussion] traian_tulbure:
For those stuck in pink System 8.0.0.046(OADH) the solution that worked for me was to install L29C900B217: https://xdaforums.com/p10/how-to/guide-to-rollback-huawei-p10-oreo-to-t3735156.

The install does not get stuck at 6% like previous ones and then you can rebrand using standard HWOTA.

Hi! I'm in a tricky situation and would like/need some advice as to how to proceed...

I have a Mate 9 MHA-L09C432 (B366 version installed in Settings/About Phone), right now i'm running crDroid 4.4 Treble. Apart from some issues/bugs here and there, everything is working normally.

I want to go back to full stock, as the issues i have prevent me from using my 128 gb sd card (due to incompatibility with filesystem, and i didn't format it) and some other things.

Right now, with crDroid functional and booteable, when i boot in fastboot mode i have:

"Phone Unlocked - FRP Locked".

All i wanted to do was flash stock recovery (i have twrp 3.2.1 fromfuture something like that installed now) to wipe data and flash stock system (extracted with Huawei extractor, i did it before and it worked), but can't flash the recovery_ramdisk, or anything at all via fastboot's commands (like system).

TWRP is accesible, even though data is encrypted (bunch of folders with random names) and can't flash any images files.

I do can flash zip of any kernel, magisk, or Gapps (although unistalled magisk and reverted to stock kernel a few days ago). I can backup partitions like kernel and ramdisk, but not system or data as i have some error.

I read around here in XDA that deleting fingerprints, pin and google account, then wipe factory reset on TWRP should do the trick to be able to use fastboot again. But i don't want to risk it because i can't flash anything related to system partition on TWRP or fastboot and would be locked out without OS, i think.

What do you suggest to do to come back to stock? I'm downloading HWOTA8 files of my device (same B366), but it needs to flash stock recovery as i see if i understand right... Some other guy even detailed that the build needs to be PointVersion or something like that, but the one i'm donwloading isn't PV...

I'm kindly asking for help, i don't want to brick my device doing something wrong.

Thanks in advance. Sorry for the long post but i wanted to explain the situation as best as i could.
[Huawei Mate 9 Guides, News, & Discussion] cesarp3791:
Hi again! I found this page on the Mate 9 forums, and was able to come back to stock. I still have the "FRP locked" in fastboot but everything is working fine, already updated to C432B370 via Firmware Finder app (with proxy) and downloaded through the stock Emui Updater app (was on C432B366 before). I'll leave the link below in case someone is in the same situation.

If you had twrp you already have unlocked your bootloader and have the code. Follow the guide from first page and restore the phone.
[Huawei Mate 9 Guides, News, & Discussion] audioman42:
I'm having lots of trouble with this step:

D. Create "HWOTA8" directory in MTP sdcard.

When I open TWRP and try to mount my internal storage or external SD card, nothing happens. Is there some sort of setting I have to enable in order to mount storage? I have already formatted my system & data, so now my phone is useless until I figure this out. I can still get into fastboot, so I don't think I've bricked it (yet).

Thanks
[Huawei Mate 9 Guides, News, & Discussion] audioman42:
For anyone who may encounter this in the future, my problem was being caused by the outdated version of TWRP included in the HWOTA8 zip folder. After installing the newest TWRP (3.2.1 I belive) via fastboot, the HWOTA8 method worked like a charm.

Or you could just create the folder with any file manager or via pc, before starting the process.

I'm a bit in panic.

i cannot understand this steps:

G. Do "Downgrade Nougat" steps to the rebrand firmware, it fails and reboot but fine.

H. When going to system press "Vol-Up" to enter eRecovery, do "Low-level format data partition".

I do everything on my P10 but I don't have the "low lever format" and I'm stucked, the strange part is that if I boot the system the phone work as usual but there isn't my region :( (italian)

Can I update with an official firmware from firmware finder? how?

Hello

hello mankindtw

sorry for my English

I have a mate 9 that I upgrade to oreo using the mankindtw HWOTA script.

everything was perfect. my congratulations to mankindtw for his work

a month later I wanted to update the phone to a new OREO version but by mistake I used the HWOTA script again and not the HWOTA8 script

The phone stayed dead. only goes into fastboot mode and does not charge the battery

Any help please ... those who created that perfect script could give me some advice ...

can I downgrade to nougat without having my bootloader unlocked? I just really need to downgrade so that I can have my network unlocked by dc unlocker since they don't support oreo mate 9
[Huawei Mate 9 Guides, News, & Discussion] Tecalote:
It's dependent on which Firmware you have.

If you are on MHA-L29 /MHA-L19 c432 b377 (GPU Turbo Update) you can't downgrade anymore, because this would destroy your phone completely.

Which Build-Number to you have?

Settings/System/About phone - Build-Number
[Huawei Mate 9 Guides, News, & Discussion] lawong:
im on c636 ,so this mean im stuck with this firmware and cant get my bootloader unlocked right.
[Huawei Mate 9 Guides, News, & Discussion] Tecalote:
If your Firmware has already the GPU Turbo Update, you can't downgrade.

How is the Build-Number from Settings/System/About Phone.?

C636 does only say the region (similar as c432) but it does not say which Firmware you have - that's why I asked for the whole Build-Number.

If you want to Unlock the Bootloader you can do it with https://imei24.com

(based on IMEI and doesn't matter which Firmware)

But costs about 30 EUR as I heard.

My Mate9 is FIX , but now is AL00 china, i can update HuRUpdater with ROM MHAL29 C432 direct in SDcard and automatic rebrand ? or Hrupdater C432 direct update cause brik ?
[Huawei Mate 9 Guides, News, & Discussion] Tecalote:
Yes, as already answered in the other Thread (you asked too..) - you can't use this HuRUpdater for rebranding.

If you would flash c432 Firmware over Chinese one you will have the next brick

Only possibility would be a method like this:

https://xdaforums.com/huawei-p20/how-to/rebrand-huawei-p20-eml-l29-eml-l09-t3779283

But for now I can't tell you if the oeminfo binary which is used in this Thread would be usable for doing on Mate 9...
[Huawei Mate 9 Guides, News, & Discussion] aureliomilitao:
i use direct update HuRupdater with 2 files Emui 9.0.1.158 C432

appear only MHA .

LGRP2-OVS 9.0.1.158
[Huawei Mate 9 Guides, News, & Discussion] Tecalote:
Okay, then this is new on PIE..

On Nougat and Oreo you got kind a brick if you did use Firmware that matches not the region of the device.

But now you flashed c432 PIE over c00 and of course you have no region that's why.

But if this is okay for you and you are happy with it...

It's your turn.

I wouldn't do that.

If I were in your situation I would had looked first if HiSuite would offer a downgrade on AL00 to get a situation for correct rebranding.

But however now it's to late.

I think the version you have currently is not in any way official supported, hence also not official update able and probably the stone for a new brick in the future.

[Huawei Mate 9 Guides, News, & Discussion] ante0:
Yeah. Noticed I was in the Mate 9 section. I have HWOTA for Mate 10. But since images are different idk if it would work. Iirc hwota8 uses permissive kernel, so you'd have to get that for Mate 9.

And I guess you could try with HWOTA8 for Mate 10, can't remember if it lets you input brand yourself or if they're preset.

https://mega.nz/#!oeATEQQb!qiP3mYlQQgZYlaS3dbY_QCwNJ-urTKyLQ2zKOA9KP8g

You could also modify oeminfo yourself using my script from here: https://github.com/Ante0/Rebrand

Or use the oeminfo binary found in hwota.

After that you'd flash oeminfo from twrp (using dd) and update to C432 using dload.
[Huawei Mate 9 Guides, News, & Discussion] IOmega666:
Found the HWOTA8 files but I guess I download an Oreo firmware that I was not supposed to, rebranded, eeverything seemed well and then, phone went black, now It's fully bricked. Can't even do something with DC-Unlocker since it doesn't work if you have Oreo.
[Huawei Mate 9 Guides, News, & Discussion] ante0:

Is phone detected as an android fastboot device or USBSER (Or Huawei COM 1.0 if DC drivers are installed?)

If android fastboot device you will have to open up back of phone and use testpoint with DC to flash bootloader files, then flash board fw through DC and repair IMEIS and stuff with HCU. After this you can update with dload to C432 Oreo (I would pick the latest Oreo dload).

If device is already detected as USBSER or Huawei COM 1.0 you can skip using testpoint.

Your device is bricked because of bootloader. It's possible you were on a firmware with new bootloader, but flashed a firmware for C432 with old bootloader.

Huawei :rolleyes:
[Huawei Mate 9 Guides, News, & Discussion] IOmega666:
Yeah, device was detected as USB SER and then I used the drivers so it can be recognized as COM 1.0. What should I do?
[Huawei Mate 9 Guides, News, & Discussion] ante0:
Use DC Phoenix to flash bootloader (from the OEMINFO tab, don't select any oeminfo), flash Kirin960 bootloader.

When the correct bootloader is flashed it will tell you.

After it is put in fastboot mode, use DC phoenix to flash board firmware for MHA (AL00 board as no other board exist, none for Lx9).

When it has finished flash you will be in board firmware. Here you must use HCU to repair imeis, serial and any info that is missing. I can't remember for sure if MHA use the UMTS or the CDMA tab. Fill out the one with the most options.

You can rebrand directly here.

When done with HCU flash dload of the target firmware (C432, hw/eu) using dload mode, download the latest C432 Oreo dload from androidhost.ru.

You could probably find MHA Board for free online but the problem is getting the bootloader files that work, so you most likely have to pay for DC anyway.
[Huawei Mate 9 Guides, News, & Discussion] IOmega666:
EDIT: flashed it. Got fastboot mode. But where I flash this board firmware?
[Huawei Mate 9 Guides, News, & Discussion] ante0:
Download it from DC using the Download button. Search for MHA in the search box that appears and find board.

I'm on linux right now so can't even check for exact name :eek:

Edit: Should be named MHA-AL00A_HLMHAAL00AM00A063_Factory_firmware_China_Nonspecific_Android_7.0_EMUI_5.0.dtgks
[Huawei Mate 9 Guides, News, & Discussion] IOmega666:
You've been of so much help to me! I'm on fastboot, I'm flashing the board software. Now, which C432 should I download? And do I do this DLOAD method?

EDIT: is this good? Is C4320 hw/eu

HUAWEI MATE 9 HW EU HLRCF MHA-L29B 8.0.0.379(C432) FIRMWARE 8.0.0 R1 EMUI8.0 05014BJB [ANDROIDHOST.RU].ZIP
[Huawei Mate 9 Guides, News, & Discussion] ante0:
Yes. That one will be good.

You extract it, put the 'dload' folder on your external sd and put phone in dload mode.

Dload mode can be booted to by plugging in USB, holding vol up + down after reboot. Or shut down and hold vol up+down+power with USB plugged in.
[Huawei Mate 9 Guides, News, & Discussion] IOmega666:
I ****ed up. Flashes board and said incomplete, then I had to go and wouldn't want to leave the device on, so I turned it off now is not being recognized by the PC. It's dead black. Suppose now I really need the testpoint.

[Huawei Mate 9 Guides, News, & Discussion] ante0:
Since I haven't opened a Mate 9 I can't help you there. But check iFixIt videos of disassembly, that should be sufficient. You can find testpoint location images in DC, under Oeminfo - change tab of Bootloader to Testpoint files.

Or Google testpoint image of MHA.

When that is done you'd unplug USB, unplug battery, plug in USB, short testpoint to ground in phone (shields covering components in phone acts as ground), phone will show up as Huawei Com 1.0 (plug back battery at this point) and you can now flash bootloader again. After this flash board again. If it doesn't want to finish, send me output log of DC.

You can find me on Telegram, I'm antezero there.
