[GUIDE]Rollback From Oreo - Honor 9 Guides, News, & Discussion

[GUIDE]Rollback From Oreo - Honor 9 Guides, News, & Discussion

HWOTA won't work with OREO, so we need to rollback manually with ADB.
this guide (more like just code memo) is for people who didn't backuped before update,
or can't go back to B183 directly by any reason (like dead capacitive keys).

https://forum.xda-developers.com/honor-9/how-to/guide-honor-9-t3653719/post75439859#post75439859
What You Need to Download
HWOTA (Windows tool)
Firmware Finder (Windows tool)
ADB and Fastboot (Windows tool)
C432B120 Firmware File
Stock NoCheck Oreo Recovery
What You Need to Have
unlocked bootloader and superuser, ADB.
adb push won't work, so you will need microSD card.
exFAT may not work on some ROMs (like Treble AOSP 8.0), so format it to FAT32.
What You Need to Do
1.
download B432C120 from Windows Version Firmware Finder and rename it (check [REBRAND] Honor 9 Thread).
why B120? bcuz it's the only firmware that leave capacitive keys and flashlights alive.
put them into microSD card root, with NoCheck Oreo Recovery .img (check How to install Oreo Thread).
insert microSD card to your phone and connect the phone to your PC and open ADB.
first of all,
Code:
adb shell
su
let's change recovery with NoCheck one first.
Code:
dd if=/storage/sdcard1/STF_RECOVERY_OREO_NoCheck.img of=/dev/block/bootdevice/by-name/recovery_ramdisk
dd if=/storage/sdcard1/STF_RECOVERY_OREO_NoCheck.img of=/dev/block/bootdevice/by-name/erecovery_ramdisk
note that 'sdcard1' maybe different, like 'E1F2-A123', base on your ROM. It's your sdcard's name.
We'll put Firmware into recovery cache and make stock recovery to flash it.
Code:
echo --update_package=/sdcard/update.zip > /cache/recovery/command
echo --update_package=/sdcard/update_data_public.zip >> /cache/recovery/command
echo --update_package=/sdcard/update_all_hw.zip >> /cache/recovery/command
reboot recovery
note that 'sdcard' is not 'sdcard1', so you don't have to change it to sth like E6F3-A496.
your phone will reboot 2, 3 times and will suggest low level format and download new firmware.
now go to fastboot and unlock the bootloader.
this will do low level format.
2.
now your phone is something like EMUI 8.0 Android 7.0, with broken build number.
do HWOTA (no need to do rebrand, just do firmware flash with update option) with C432B120 we downloaded before.
This will make your phone Stock C432B120.
3.
Let's Go back to B183, the newest Nougat ROM.
download Firmware Finder for Huawei app at Play Store.
choose C432B183 and update it with proxy.
maybe you got 'yet approved' error,
but there are quite numerous C432B183 so check every single one of it.
There is one that is flash-able.
4.
TADA, now you rollbacked your phone.

I think you can also rollback with Hisuite on PC, I did a few times to rollback from beta.

I don't like your guide because :
-You're flashing a B120 firmware which is not to rollback from oreo when there is already a B183 oreo's rollback available for this on FF.
-You have to flash it 2 times to fix your build version issue (maybe because it's not a rollback firmware).
Please note that your step 1 & 2 are the same, you just did hwota manually on step 1.
-You then updated from B120 to B150 when you could have directly updated to B183 not for oreo's rollback on FF.
Sorry.

Never tried that, but it would be much more simple and clear. This Thread will become useless though lol.

1. isn't that rollback for beta B321 and disables capacitive keys and Flash lights with B360a?
2. that's the point of this guide, since HWOTA is not properly working with oreo. you can just change the strings inside the hwota.sh if you want to.
3. no you can't jump to B183 directly from B120, shows approve error. any other firmware except B150 shows the error, same to B183 from B150.
Thx for the opinions though.

Nope, it's a rollback from oreo B3xx.
It's still has to be tested if rolling back from B3xx to B183 mess with capacitives keys.

Sorry but you are wrong : by using FF on B120, I can guarantee you that YOU CAN update to approved B183 using the full ota update ( the B183 one that is not to rollback).

I found out that We do can OTA to B183 directly, so I changed the GUIDE + some minor change.

2. now your phone is something like EMUI 8.0 Android 7.0, with broken build number. d
I didn't get this point. i mean with hwota (link you put in) we have just 2 options. update and rebrand. we have no choice for just flashing. sorry for my bad understanding.

do update.

which version of B183 are we supposed to take? I choose the last one: 116404
but I'm not sure it's the correct one. (changelog tell it's a rollback firmware)
seems the good one is the 111176 (changelog is not about rollback)

Don't follow this outdated OP and thread which were never right in the first place.
For rollback use HiSuite or HuRUpdater.

You updated to a test build. You'll probably need to rollback to Marshmallow using Huawei's rollback package. You could try using the Charles method... Look in the guides forum for how to do a Sympathic update.

Did the roll back. Wasn't able to flash the 2nd package the way that it described in the rollback PDF but it worked in the method described in the PDF that comes with the 6.0 firmware download (applying update from SD card). Both packages took a couple tries updating, not sure why.
I ended up on the test build using the Charles method last time.
Used the Firmware Finder (Team MT) proxy route this time and easily made it to B360.
Thanks for your help!

Can you help me with the steps,i am now in the NRD90M test keys mode

Hello
If you have got a FRD-L09 C432, you have to dl and flash the B131 before upgrading toward Nougat ( B360 for example). You have to use the dload method ( dl B131 and extract then) and you place the Update.app in a file named dload in a SD card in your phone. Turn on your phone and you use the 3 buttons ( VOL +, VOL - and Power in same time until the tel enters in flashing).

For my mind, you have to do a rollback toward MM. So, you have dl two files in official Honor site! Then, you apply the dload method ( extract and put an update.app in a Sd card in a file named Dload) and flash by the three buttons ( Vol+, Vol- and Power) for the first file and repeat the same operation for the second.
I hope it works.

There may be 2 zips for model. One is main zip and then one for data zip. You need to flash both. It will bring back the updater app in setting.
For NRD TEST KEY, you need to flash the oeminfo file. Let me know if help required

You need the oeminfo file of this version and then need to dload again to be able to get rid of nrd test keys. There is a detailed procedure in my debranding guide in signature but you need to have oeminfo file for your model and then firmware.
Or you can try debranding guides for honor 8 to other variant to have Google also.

[firmware]STF-L09C432B150 - FullOTA Rollback

Hi guys,
this morning was uploaded STF-L09C432B150 Rollback update (FullOTA) on Huawei server. Here are download links:
http://http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1906/g1642/v105908/f1/full/update.zip
http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1906/g1642/v105908/f1/full/STF-L09_hw_eu/update_full_STF-L09_hw_eu.zip
Changelog:
Code:
This update will roll back your phone's operating system to Android 7.0 (EMUI 5.1).
Rollback notes:
1. Please make sure you are currently using the official version of Huawei EMUI, and that no unofficial updates have been installed. Otherwise, there will be risk of an unsuccessful rollback, and an unknown error may occur.
2. Make sure that the current version has not been unlocked or rooted.
3. All user data will be deleted in the rollback. Use an SD card, computer, or Cloud storage to back up all important data before rolling back your phone, and make sure all backed up content is complete and effective.
4. Make sure your phone has more than 50% battery remaining.
5. If you experience any issues during the update, please call the Huawei customer service hotline or visit an authorised Huawei service centre for assistance.
6. The system will restart after the rollback. This will take about 10 minutes. Following the update, your home screen will automatically display the EMUI 5.1 theme.

This is rollback update only, it can be used only if you are using greater official updat from Huawei running on Android 8. and it will downgrade you from Android 8 back to Android 7.

I have now beta Oreo STF-L09 8.0.0.323(C432log). So this files are for rollback from this version.
And how to do it? First put update.app from first ZIP file do dload directory and flash it and then do the same with second app? As in this thread: https://androidforum.cz/advanced-search/?keywords=dload&t=76974&sf=msgonly (czech language)

I have a retail german version of the Honor9
After installing 150 you can also update to 180 via official system -> Update -> Download full package

wow I hope this means Oreo is comming officialy, mine was just updated to B180 since the one that came on the box, I think will be weird get two updates that fast, but I hope it comes soon

It's not ok for me. Not rooted, locked bootloader but when it restarts in recovery it give to me software failed error
I'm really hating Oreo (beta) in Honor 9 because performances are poor and battery too.

Did you do it like explained? Either in Huawei HiSuite or the Phone Manager (App) - No hacks or inofficial ways..

Hello dying_sun, i have the same problem.
Honor 9, STF L09 (Europe), now with OREO B360
- unlocked bootloader
- TWRP 3.1.1
- rooted with SuperSU
--> after some days I unrooted my device and locked my bootloader
(I use multitool for TWRP and stock recovery)
After unrooting OREO ota came and a realised that the capacitive buttons are not working. Tried different settings, only the home button works
What to do?
--> Rollback to B120.
I downloaded firmwares from different sites and tried different methods
3-button update: Installing failed
dload method sd card: Installing failed (NTFS format, 32 GB)
dload method internal memory: Installing failed
*#*#284...#*#* method, upgrade from sdcard: Installing failed
I tried to flash a kernel.....img (here in forum "Capacity fix" topic) but when I install it over TWRP the device asks me in which flash memory should it be flashed and I do not know what to choose. (system, ODM, splash2, recovery_ramdisk, cache)
I also tried the HWOTA method, but I get the message, that "recovery2" could not be written into ramdisk or something like that and then it stops.
Possible that I did not consider a little detail
Could you please tell me which firmware from firmware finder did you use and which method you choose to make rollback?
Slowly I get desperated with the phone.....
Thanks a lot in advance

First : Are you on nougat or oreo now, and what's your region ?
your phone is booting ok in system, but no capacitives buttons ? So you'll like to fix them before updating ?
When on nougat, for flashing the dload way a service repair nougat firmware, I think you must have formatted your SDcard to exFAT and not ntfs.
I think when using service repair dload files, you must use the same region files the phone is actually.
For info :
3-button update,
dload method,
& *#*#284...#*#* method,
Are all the same.
You also tried the HWOTA method, but which hwota files did you used ?

Hello oslo83,
The phones Emui is now Emui 8.0.0, B360.
I have an unlocked bootloader, booting is ok (message about unlocked bootloader comes first)
Capacitive buttons and flash light are not working --> I would like to fix them (this is the reason why I try to rollback to B120.
I tried to format to FAT 32, but not possible to copy update.app, because of size. With NTFS it worked. --> I try format to exFat
I downloaded a full-service-repair-package for europe from the site 4pda.ru.
Should I use Firmware finder?
What do you mean with "which HWOTA fileS? --> update.zip / update_full_data.zit and a third one..... comlete package, as described.
Thank you in advance.
Andy

Maybe to late to use dload as i don't think flashing dload nougat over oreo will work.
And the only public dload service repair firmware available seems to be only nougat.
And downgrading is maybe not usefull as it seems there is a simple fix for you now by flashing kernel...

No, I meant where did you get your hwota8.rar from ?
Where you using the new one for oreo or the old one for nougat ?
So for you the better will be to flash kernel fix : https://forum.xda-developers.com/newreply.php?do=newreply&p=75772700
Help yourself, follow the instructions and don't try to install it over TWRP as you did before.

dload method, no firmware file for Nougat i download is valid!

I need help! I often softbrick my device, but can be fixed by using official 6.0 update.app However updating back to emui 5 takes way too long. But every firmware i download from huawei firmware finder isn't valid for dload for some reason! Help!

Did you already tried with firmwares listed as "FullOTA-MF-PV" available on hwmt.ru site, section firmware database? The Point Version is a firmware that must work while you're executing a dload method flash, the safest usually.
What's your build number? I'll provide a valid firmware to use with dload method.

BLN-L21C432 but i didnt see any MF-PV for b360+ so i dont think there are... that, or i am blind

Use team mt tool extract update.app from firmware and use Huawei extracter to provide required file

The biggest one with dload method first of all, then the other two dload too (or flash by TWRP)

TWRP says command unknown, and how am i supposed to flash the second one? (There is no third file) Do i dload big one, then boot to EMUI, then shutdown, extract SD, switch dload folder, and install the second?

Did the failure brick your phone? or the phone just reboots itself normally? are you sure that your firmware is approved first for installtion before you apply it? (you can know this using Firmware Finder by checking if it's approved first or not for installation by Huawei)

Possible To Flash Oreo Rom Via TWRP Recovery?

I am currently on Android Nougat stock.
The bootloader has been unlocked and TWRP recovery has been installed.
I would like to update to Oreo but have been unable to do so.
This guide was followed [urlhttp://www.droid views.com/install-android-8-0-oreo-based-emui-8-0-huawei-mate-9/][/url] (but was unable to get past option 4) (I left a space after droid as the link is getting blocked, just put ********** together.)
''Double-click on the Replace_Recovery.bat file in the extracted HWOTA8 folder. This will install TWRP recovery on your device.''
I keep getting a failed notification when trying to do so. The handset was in fastboot mode but refuses to update recovery.
Am I able to update to Oreo with the old TWRP recovery & update it after? I am running the old Nougat version.
Option 7 I also got stuck on. '' Create a folder named HWOTA8 on your device’s internal storage.'' whilst connected via USB to the computer.
I am unable to view internal or external storage when the USB is connected to the computer. When viewing internal/external memory normally I can see items as normal in external SD card but the internal memory files all appear jibberish even in recovery.
What am I doing wrong? I have been unable to find any clear guides of how to update from Nougat to Oreo including flashing the rom, flashing recovery and root.
Thanks for those able to help.
PS. I'm a new Huawei Mate 9 owner and have only just received the device several hours ago which is why I'm rusty. Compared to my previous Sony Xperia XZ Premium it is much more complicated. Sony was far easier to flash recovery and flash roms via recovery.
I am having the MHA-L29 international version.

Device now bootloops after following the guide of flashing SuperSU in recovery. I did what was said and received ''error 9'' after flashing the files.
Now bootloop.
Good news at least recovery is working but unable to boot. How to I update to Oreo with updated recovery & root?

Otherwise is THIS guide safe to follow:
https://forum.xda-developers.com/mate-9/how-to/guide-rebrand-chinese-al00-mate9-to-t3554656

Could not even get past option 4. ''Do oeminfo backup in twrp,you should have a folder name twrp, inside this folder there is many subfolders.
In last folder there is 2-3 files,those files should be replaced with c636 oeminfo: http://www.mediafire.com/?szws87sk7rrkqr6''

The guide in OP is outdated, and it only has the oreo beta builds.
Do you know what your current firmware build is?
MHA-LxxCxxx
(It should be printed on the box of your Mate 9)
Next go here http://pro-teammt.ru/firmware-database/ and enter your model and cust in the search box (Example, MHA-L29C432)
Official Oreo builds begin at B360, if you happen to be at C432 the latest is B364 (Ok, it's B365 but it seems to be a test build and was released before B364 so January patches.)
Click the 'update' link in the FullOTA-MF row, download update.zip.
Click on the 'file list' link in the FullOTA-MF row, copy link of update_data_full_public.zip and paste into a new browser tab, this downloads the zip.
Do the same with L29 or L09 hw data, depending on your version.
Next rename update_data_full_public.zip to update_data_public.zip, rename the L29/L09 hw data zip to update_all_hw.zip.
Place update.zip, update_all_hw.zip and update_data_public.zip in the HWOTA folder on your sdcard.
Download this zip: https://mega.nz/#!RaAQDLqY!pgBcA5tcy4ewvROUxei3af59hns4YtkeFPC5_WCyV6g (Note, this is only for Nougat to Nougat or Nougat to Oreo, does not work in Oreo as partitions changed and it flashes the NoCheck recovery to the correct partitions in Nougat. It will not flash correctly in Oreo)
extract and put hwota7_update.zip, MHA_RECOVERY2_NoCheck.img and MHA_RECOVERY_NoCheck.img in the HWOTA folder on your micro sd.
Put back mSD in phone and boot to TWRP, flash hwota7_update.zip and wait.
Phone should now reboot and start updating.
This is basically the HWOTA8 zip for updating Oreo or downgrading to Nougat, all props to @mankindtw.
All I did was change the partitions to flash so they match Nougat's partitions.

Good thing I never went ahead with that!
I'm on international MHA-L29C185B182.
Thank goodness I was able to restore Nougat as I backed up with TWRP recovery.
However, what is the easiest way to upgrade to the latest Android Oreo 8? At the moment I'm on stock 7 Nougat but am rooted with TWRP recovery.

Check my post, I edited while you posted this.
Or you can use this one, it's basically the same anyway, only difference is that you use a .bat file: https://forum.xda-developers.com/mate-9/how-to/guide-mate-9-flash-update-package-t3593108
Use the same steps as I wrote above for downloading the update files as this was not the way to do it when that guide was written.

Thank you so much ante0 for all the information, it was very helpful. I am now downloading the above three files. Once complete I will rename them as mentioned and flash hwota7_update.zip in TWRP recovery. Will let you know shortly the outcome!

Cheers ante0, finally got my phone fully updated to Android 8 Oreo following your guide. Thank you so much! If it was not for you this would not have been possible!
The other links I was looking at were outdated as you mentioned and the instructions you provided were better. I appreciate your time to help me.
Upon booting, my EMUI version is now 8.0 and Android Version 8.0.
I will now follow this link for getting root:

Great. I would suggest Magisk but that's up to you to decide
Bootloader getting locked is normal when updating Nougat to Nougat and Nougat to Oreo. Oreo to Oreo is stays unlocked.

I did not see any guide for Magisk, guess I missed it.
Anyway there are pros and cons for both, though I also prefer Magisk. Either way they both do the job, root access.
All is good now. I am very happy with the phone. Still not even been 24 hours since I received it yet already the bootloader has been unlocked, TWRP recovery and root. Nice :good:

Great and very helpful thread. thanks for everyone who's contributed to it. I'm trying to do the exact same thing coming from ROM Aur. Do you think I can use the same exact process is yours coming from a custom ROM? Did you have to do the boot loader unlock in order to Root? If there are no custom roms then perhaps the boot loader unlock is unnecessary? In order to install Magisk to root, what are the prerequisits? Do I need to reinstall TWRP? If so , is there a link to the correct version? Are there any other pointers that you can give me that you found out while doing this whole process? Thank you so much

You can do the exact same process, however, I strongly suggest you follow the above guide from ante0. His guides are clear and upto date. Other guides were unclear and old not being upto date.
And yes, you must have an unlocked bootloader to flash a rom, however it is very easy to do. There are many guides which tell you how to do so. Simple fastboot commands when your phone is set to fastboot mode. You only need the unlock code via Huawei's website.
With regards to Magisk/SuperSU, yes, you must have a working recovery in order to flash either one. Without recovery you cannot get root access. I suggest you flash SuperSU as it is far easier than Magisk, a simple two step procedure!
What Android version are you on? Nougat or Oreo? Beware that when flashing recovery and root, it must be for the correct Android version. And of course if updating to Oreo, once again you will need to flash recovery and root made to run on Oreo to prevent issues and boot loops.
Do you not have the box that came with your device? I am guessing you have the international MHA-L29 version as I do, but you must be sure.

The bootloader (i.e. fastboot) is always locked (btw, is there an easy way to unlock FB Lock ?), you probably mean the 'USER Lock'. And the 'USER UnLock' is damaged only if you flash some random oeminfo files (which is a very dumb decision anyway).
This mechanism is documented in the USENIX paper i have linked in the OEMINFO thread.

It may be "easier", but Mate 9 is probably one of the most unbrickable smartphones that i know, because it can be recovered even if you manage to destroy 'partition table+xloader+fastboot' (the really critical parts, other partitions can be recovered without opening the phone case).

Yes I intend to follow the awesome guide from ante0 (thanks for that ante). I'm on Nougat currently. After following the above method, I guess I will have a fully factory locked phone? SO, I will have to first install recovery, then root. Correct? I do have the box but it only says the model number MHA-L29. Nothing on firmware but since its a US phone bought here, I'm fairly confident that its a MHA-L29C567B183. Although when i installed ROM AUR I used the version for L29C432 and it worked. Which one would you try if you were me? Will I brick the phone if the version is incorrect? If that happens, how do i return to oreo stock from there? Do you have any links for the right Recovery and root?
Thanks and sorry for so many questions.
UPDATE-- So have an update. I was able to install oreo using the method listed above. everything seems to be working fine. however I'm getting an error 255 message while creating a backup I'm using TWRP. Thinking that my data partition needed decrypting, I deleted it and rebooted the phone. Set it up and then went back into TWRP. I'm still getting the same backup error. any ideas? The route also installed and works fine . My concern now is that I would end up with I found that cannot be backed up with TWRP. BTW. I installed TWRP 3.2.1-0 from here https://forum.xda-developers.com/mate-9/development/recovery-twrp-3-2-1-0-oreo-t3734967.
Thanks

^ 1 Thing hopefully you did not forget, before flashing the rom, you must ''wipe data'' from TWRP recovery otherwise you will get bootloop and the encryption issue. Did you wipe data from recovery prior to flashing? Encryption is removed/disabled when wiping data in recovery.
Glad you got somewhere at least. If it wasn't for the guide from Ante0, I'd still be bootlooping on Nougat.

How to downgrade firmware?

I have a new SHT-AL09 with 172 firmware and a locked bootloader.
This firmware prohibits DC-Unlocker from reading the bootloader unlock code.
How do I downgrade to a previous firmware?

Try HuRUpdater: https://forum.xda-developers.com/mediapad-m5/how-to/unbrick-mediapad-m5-install-otas-t3856312
You should be able to install TWRP even with locked bootloader. Download the full OTA and follow the HuRUpdater instructions.

I think there is very little risk. Even when the downgrade fails, you should be able to just flash 172 again with HuRUpdater to restore back the original state. Don’t try to rollback too far, install the last version prior to 172 and try dc unlocker again.

I asked on a german Forum and got the response that TWRP cannot be installed with locked BL - which I find somewhat logical - however, I am reaching for the unlikely event that I can get an open Bootloader somehow....

I am a little confused by the instructions. I have to put the TWRP.img in the folder on the SD Card together with the HuRUpdater.zip file and the firmware zip files. But then what? How do I flash anything?

You should be able to install TWRP even with locked bootloader. Download the full OTA and follow the HuRUpdater instructions.

I cannot flash TWRP with my locked bootloader. I get an error FAILED (remote: Command not allowed) when I try this when the M5 is in fastboot mode: fastboot flash recovery_ramdisk twrp.img
Found this on the last page of the HuRUpdater thread:
Absolute prerequisite: unlocked bootloader
I don't have this so is there another way to downgrade the firmware?

OK, bummer. You can try the dload method, not sure if that works for downgrades though: dload

I tried that already. It starts installing but at 5% it stops with an error: Software install failed

Firmware finder is probably your best bet: https://forum.xda-developers.com/honor-6x/help/to-bln-l21c185-t3578790

Firmware Finder apparently does not work with EMUI8 anymore.
And there is no rollback package available for the M5.
I have always found a solution for these kind of problems on XDA (and I have had a bricked device or two) but for the moment I am at a loss.
Guess I will have to learn to live without root and with the stock Huawei firmware...

Sorry mate, tough luck. ? I think the hardware of the device is pretty nice, but the stock firmware is so full of crap and spyware, totally unacceptable.

when downgrading using dload, check for xloader version first.

I jut downgraded my M5 AL19-CMR 8.0.0.172 back to 8.0.0.161 without any problems.
I used the firmware file from https://androidhost.ru/ I used the 8.0.0.161 dated 17.07.2018, I am in Germany and have as it seems the european version of the tablet!

For my SHT-AL09 there is no older firmware on androidhost.ru than B172.
I have downloaded the B163 and B152 firmware through Huawei Firmware Finder and I can extract it with HuaweiUpdateExtractor but then what?

I have a new SHT-AL09 with 172 firmware and a locked bootloader.
This firmware prohibits DC-Unlocker from reading the bootloader unlock code.
How do I downgrade to a previous firmware?

From my latest findings:
Bootloader need to be unlocked for DOWNGRADE to sucess in firmware mode with a working dload service repair firmware.
With locked bootloader you'll only be able to DOWNGRADE in eRecovery mode with the latest firmware approved (It will be a downgrade only if said version is the latest approved fetched in eRecovery and inferior to yours current)
I did not find yet how the latest firmware shown/available in eRecovery is fetched into eRecovery. I think it happens in normal mode sometimes when you're connected online. You'll then have to reboot later to eRecovery to be shown...
Now, for your SHT-AL09 B172 with august 2018 secutity patches, the only way to downgrade is to get your unlock code and vice&versa.
Luckyly, third-party sellers are just starting to provide working bootloader's unlock code online for around 30~50€.
New devices are supported.
You just pay, gave them Model ID, IMEI1, Serial, Product ID and you'll get your code within the next hours.
You just pay, gave them Model ID, IMEI1, Serial, Product ID and you'll got it within the next hours. I already tested it on few devices.
FunkyHuawei does it for 130€ per device with other services included.

I am also interested in rooting M5. Where you able to downgrade the tablet from B172 to B161?

No

I am also looking for a way to downgrade my Mediapad M5.
I have Hauwei MediaPad M5 CMR-AL09 (C432) currently running 8.0.0.192. dc-unlocker does not work with this version so I can not unlock bootloader.
This is what I have done:
* Format external sdcard into exfat. I used my Ubuntu Linux computer for this, sudo mkfs.exfat /dev/sdx1.
* Put the empty sdcard into the tablet.
* Download android app "Firmware Finder for Huawei" and I choose CMR-AL09C432B161 (8.0.0.161) FullOTA-MF. Downloaded that into update.zip file.
* I use android app FX File Explorer to get read/write access to the mediacard and to create the dload folder.
* I used android app FX File Explorer to extract only UPDATE.APP file into mediacard and the dload folder. The file is around 4.2GB in size when extracted. I also tried to put all files into dload folder but with the same result below.
* Open dialer and type in *#*#2846579#*#*. Go to software upgrade and choose SDCard upgrade. The tablet will now restart and do the downgrade.
* Problem now is that it goes into 5% and then fails.
Am guessing there is some protection to downgrade into 8.0.0.161 version.
Guys.. Let's solve this. :crying:

Hmhm. I downgraded my Mediapad M5 Pro from 8.0.0.172 to 8.0.0.161
This is what I did:
https://www.android-hilfe.de/forum/...uer-huawei-mediapad-m5-ab-08-2018.892304.html
(short paraphrase of my downgrade-"guide" at android-hilfe.de)
1) check xloader-version
2) Download the potential downgrade from androidfilehost.ru (this worked for me, again, M5 PRO (CMR-AL19), Europe! https://androidhost.ru/byu )
2.1) The structure inside is firmware-name>software>dload
2.2) copy dload onto your SD (root directory)
3)The downgrade-process
3.1) power off the device
3.2) Volume up AND down AND Power Button for some seconds
3.3) Downgrade should start! If folder is not recognized, a Pink screen will appear - just do it from the start.
After rebooting, you should then have the version you wanted to downgrade to.
I have done this several times ( accidently updated once or twice )and it worked without any trouble.
The 5% thing: it stayed at 5% for quite some time. But it always went on after some time, at least for me
I read somewhere, sometime ago that with Firmware Finder the security check that is somewhere included in the file is not removed and therefore you cannot use those files. It seems imperative to me that one uses androidhost.ru (no guarantee that this information is right - so feel free to correct me )
ah, sorry only now I realized that you specified CMR-AL09, we had someone do it for SHT-AL-09, sorry :-/
but why don't you try the files from androidhost.ru (download the correct firmware! I linked the one for the M5 Pro! )

Thanks kev1807 for the input.
I tried the firmware you linked to for Huawei MediaPad M5 CMR-AL09 (C432) version 8.0.0.161. It did not work.
I found the version 8.0.0.190 on androidfilehost.ru and that worked. So I have now downgraded from 8.0.0.192 to 8.0.0.190 but that will not help me much. Downgrading into 8.0.0.161 still does not work.
I was on 8.0.0.192 and manage to use the file
"Huawei MadiaPad M5 CMR-AL19 hw eu Cameron-AL09A 8.0.0.190(C432) Firmware 8.0.0 r1 EMUI8.0 05014XYB [androidhost.ru]"
I have tried these packages but they have not worked.
