Hi
i'm on B360 firmware (FRD-L09) , i want to rollback my phone to b131 and clean all the mess on my phone to update properly my device but when i put dload rollback on external sd root , i have this message on phone : failed to install software
Same with dload folder in internal storage.
My bootloader is unlocked.
Thanks in advance
Did u managed to solve the problem? Because I'm facing the same atm.
I faced this issue recently. It would stick at 5%. I downloaded this b131 and managed to flash successfully.

hello, i will try to explain my problem :
My honor was bricked by an error of flash.
I have "repair" it by a way found here on xda : flash boot.img, cust, recovery, system, and after i have could make the update by dload.
Then all was ok under the firmware LO9C432B131.
But now, i can't update to B360...
Before my brick, i had the ota update to B360... but now i have nothing....
If i try the update by dload, it says : "problem compatibility"
I have downgraded to B120 and ota update was good for B131. But nothing for B360
If someone can explain me...thank you so much (actually the phone is no rooted and relocked)
Hi there. Go through the entire rollback procedure and you will be fine: https://forum.xda-developers.com/honor-8/how-to/guide-downgrading-unlocked-rooted-twrpd-t3549281
Put the update.app file in a folder called dload on a SD card. If you haven't got one, flash twrp in fastboot and when in twrp you'll be able to transfer them to internal storage from your pc. Then follow the instruction above. That's how I unbricked mine. Good luck.

I don't think you understood what OP is saying. He successfully rolled back to MM but he cant go to Nougat anymore.

Yes, but I believe the issue comes from manual flashing of partitions. I have also tried that when my phone was dead and the recovery and eRecovery always threw "package incompatible" error. I think restoring the entire file system to factory condition (which happens during the rollback process) is the sure best way to fix all issues.
Thanks for your answers,
I finally got the update with the charlie app...(not easy this method !)
But now i don't know if ota will be ok...
I will perhaps do the rollback as you said to restore the entire file system...
My Mate 8 L29 is currently on C432B192 again. I said 'again', because I was already three or four times on EMUI 5. (I tried to root it but it failed Everytime, so I had to rollback)
Yesterday I wanted to try again to root B560 and began to search for the update, but - nothing. I tried it via update app , HiCare app and HiSuite on PC. I don't get the update offered. (I also deleted data and cache of those apps)
I'm currently rooted, so I tried to unroot, install stock boot image and recovery .. but same problem: still not getting the update.
Now I'm wondering why this is happening .. I had that same case before (B192, rooted etc.) and I always got that update offered.
Does anyone have a solution for this ? ( Except the manually method via TWRP .. this was never working for me)
Thank you for your help!
Hello everyone ...
I was trying to root my mate 8 next+L29c185b560 ... And I did with twrp

You need rollback package to get it back to normal.
Since your model is L29 & you are nougat.
Go to this site http://consumer.huawei.com/sg/support/products/downloads/detail/mate-8-sg.htm?id=91647
Download the file
Extract the update.app
Make a folder on your sdcard and name it as dload
put this update.app in that sdcard
now you do the dload method
you can do it two ways
one way is
the 3 finger rule while bootup
just press volume + volume - power button together and hold until you see EMUI verifying package
then release your fingers
it will rollback to marshmallow
now you have to update it to another stock firmware (marshmallow)
remember at this point it is in global firmware it might show build number as C900 or something.
you can check it in the settings - about -> build number
you have to then update it to your model firmware
L29C185BXX
I found the stock firmware from another thread for your model
This is L29C185B200
http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1076/g104/v65326/f1/full/update.zip
once again
download the file,
extract the update.app &
then put the update.app in dload folder on your sdcard
and then do dload method.
second way of dload is
open dialer
type *#*#2846579#*#*
click on "software upgrade"
and then -> SDcard upgrade
follow the instructions on the screen
and it will finish the dload method in next few minutes.
That's it. now you will be on Stock ROM with fully functional OS.
after this you will either get OTA updates or you can download using HiCare
or you can download the stock firmware from another thread
or
you can use firmware finder to get stock firmware for your phone. Get the latest version.
If you finish all these steps then I will tell you how to get to nougat if you have any trouble
Hope you find this information useful.

You are rooted & if I read correctly you also have TWRP installed.
If you are unlocked, rooted & have TWRP - then you can install custom roms.
but if you want stock roms, - you need Stock ROM, Stock Recovery, Locked bootloader.
First you need the rollback package from EMUI4.1 to EMI 4.0 for L29C432 is below
https://www.hidrive.strato.com/lnk/0mlDFqqy
Rollback package for L29 to downgrade from EMUI 5.0 to EMUI 4.0 marshmallow is
http://consumer.huawei.com/sg/support/products/downloads/detail/mate-8-sg.htm?id=91647
So choose the right version based on the firmware you are having on your phone. If you have nougat choose the second link and if you have any other version then choose the first link.
Download the file, extract the update.app
then you have to do dload method
create a folder named dload and put update.app in sd card
then
go to dialer
press *#*#2846579#*#*
select
sdcard upgrade
and then say yes
that's it
you will come back to stock (global) version. build version will be C900BXX
now you need stock firmware for L29C432
you can download the stock firmware from here. Below tis the link for L29C432B180
http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1076/g104/v51244/f1/full/update.zip
Stock firmware for L29C432B192
http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1076/g104/v63059/f1/full/update.zip
Here you have the option to either go for L29C432B180 or L29C432B192. (if you choose B192, then you will save time and reduce few steps, because you will get system update to B560 immediately once you change the region to Ireland in Hicare app)
do the dload method again
extract the file, put the file in dload folder in sdcard ,
either use dialer or use 3 button rule to finish the dload process
now you are on L29C432B180. / L29C432B192
From here you can use another dload method to go to B192 - > system update (OTA) -> B560 or B580
if you get a blank screen - > do factory reset
if you get "verification failed " in red color - > unlock bootloader again and proceed with the steps.
This rollback package will save you in case of any problems.
Once you go to nougat B560
you can update to Kangvip B577 - pre rooted rom - its awesome - Root stable , excellent battery lfie. - everything is working perfectly.
I will give you those steps and links if you succeed in getting to B560 after all these steps.
I am sorry that this is a very long post and many steps but I can assure you that it is worth.
Ultimately you will get to nougat & with full root using Kangvip B577.
Hope you succeed

Someone have a good rom like stock android or emui 5 official ?
Thanks... :crying:
Really..
Have you tried to rollback? Or why do you have FRD-L09C900B300? It's a rollback package.
I suggest you to use dload method to rollback to B131.

I have been stuck on B300 also when trying to rollback once or after trying to upgrade via charle method i don't remember. But I end up getting out of it and rolling back to B131 by creating the dload folder with the B131 frimware in my sd-card, and it works. On internal storage it kept telling me something error or invalid packet.

i am stuck at C900B300 version. I am on L-09 model. when i am try to follow last step that is create dload folder in sdcard root and save marshmallow app then press power+vol_down+vol_up button update didn’t take. It show software install failed message, update package doesn’t exists!! automatically delete dload folder.Please let me know what i can do to complete downgrade operation
It took me 2 full days to finally successfully upgraded my ancient firmware (L09C16B170) to the updated version (L09C432B397). There are a lot pieces of information that I gathered from this forum and all over the internet that collectively helped me navigate this ordeal. Just want to share it with anyone who is in the same boat, although I know that P9 won't last for too long since P10 has been out for a while. However, if you still want to revive your P9, keep reading.
Requirement
Before reading, you need to understand ways of entering different modes of your P9 phone, which will be used many many times during your upgrade:
Enter recovery mode (also how you enter TWRP) - see this GUIDE
Enter fastboot mode - see this GUIDE
Enter manual upgrade mode (also called dload method; This is NOT TWRP method) - see this GUIDE. Please IGNORE any software or download information in this guide. I want you to refer to this guide for how to do it, NOT what to use or download!
You also need to download and know how to use ADB tool which is quite simple. Search the forum or google and you will find plenty of information and the download links. If you hate command lines, you can even use the GUI version from here.
You will probably also need to use Firmware Finder for Huawei (HWFF) to download firmware of interest for manual update during this process. HWFF is an app that can be installed for free via your phone Google Play Store. The downloaded firmware is saved under the HWFF folder in the internal memory. You might need to unzip these files for upgrade via dload method or directly via TWRP method without unzipping. However TWRP method requires you to unlock the bootloader and install TWRP in the phone (see below for details).
First step - debranding
If you are already on C432xxxx, you might just skip this step. I followed this thread partially (Debranding Guide by Z-Blade), since the whole thing doesn't work for me 100%.
Z-Blade did a fantastic job describing how to debrand his C34 firmware to C342B361. My original version is C16B170 which is a South Africa branded firmware. But I found certain steps in this guide could be omitted and certain steps didn't work in my case. Here is my modified version based on Z-Blade's version:
1. Unlock your bootloader and install TWRP
How to unlock bootloader? Follow this GUIDE. Even though it's for Huawei Ascend XT. It works for P9 as well. You only need to complete Part 1.
After you unlock the bootloader, install TWRP. Depending on which firmware version you're on, the version of TWRP that might work for your device changes. I encountered numerous booting loops due to incorrect version of TWRP. Finally I found that these three versions work for me (3.1.0-0, 3.1.1-0, 3.1.1-1). Always go with the highest version first (3.1.1-1). If you find yourself stuck in the booting screen, long press your power button until you get out of it and install another version of TWRP. Please go to TWRP official website to download TWRP for Huawei P9. Follow this GUIDE to install TWRP recovery on your phone.
2. Flash OEM info file for C432
After you unlock the bootloader and install TWRP recovery, download oeminfo-huawei-p9-eval09-c432.zip from this THREAD and flash it via TWRP method.
3. Flash C432B136 firmware
Download and flash the dload-huawei-p9-eval09-eva-b136.zip via dload method from this thread. After flashing and rebooting your phone, you should be on the L09C432B136 firmware. NOTE: If it boots up to a white screen asking you to enter password, reboot into recovery by holding volume up when you powering up your phone, do a wipe partition and factory reset. You may need to reboot your phone a number times before the phone boots up correctly.
Up to this stage, you have debranded your phone to an european version.
Second step - stepwise firmware upgrade
1. Update from B136 to B166 or B182
As mentioned in Z-Blade's original post, many people will not be able to directly update from B136 to B182. I am one of them. Go into the updater in the phone setting, refresh "check for update". If you can receive B182 update, by all means go for it. If you only receive B166 update, go for it as well. After B166 update and rebooting your phone, check updater again to see if you receive B182 update in the Settings menu. If this method does not work, manually update to B182 by following the steps here via dload method.
2. Update firmware from B182 to B360/361/378 and also upgrade OS from Android 6.0/EMUI 4.1.x to Android 7.0/EMUI 5.0
According to Z-Blade, "After your phone has rebooted and you are on the B182 firmware, you need to now update the firmware to B361 via Huawei Updater 2.0". However, in my case, I tried many times and always failed at this step. I found a workaround by updating to B360 instead of B361. Please follow this GUIDE to update to B360 or B361, whichever works for you. However, please pay attention to following change that I found critical:
- The version of Huawei HiSuite is critical for the success in this step. The GUIDE provided Hisuite download link (version 5.0.0.301_OVE). However, it does not work together with Huawei Updater 2.0 in my hands. This error has wasted me almost half day. Instead, I finally found out the problem and went to HERE to download the version 5.0.1.300 and it finally worked
- However, if even after HiSuite and Updater both work together fine the update does not proceed successfully (the updater might get stuck), you need to update it manually via dload method. Search EVA-L09C432B360 or EVA-L09C432B361 in Firmware Finder for Huawei as mentioned above and download the Full-OTA version (~2G). After download, move the corresponding folder containing firmware zip files under "HWFF" folder in the internal memory to the external SD card. Unzip the firmware file and update your phone using dload method. You may also try TWRP method which can install zip files directly, but at this point, you bootloader will be re-locked and TWRP will be gone. You need to unlock the bootloader and re-install TWRP again as mentioned above.
After you successfully update the firmware to B360 or B361, now you should have Android 7.0 and EMUI 5.0 on your phone. Now go to the updater in your phone setting. You should receive B378 OTA update. Proceed with the update...
You might not need to strictly follow following steps to update your phone to any firmware beyond B378. However, since a lot of new ROMs are based on B380+ or even B390+, if you want to use those, you might need to further update your firmware first.
2. Update firmware from B378 to B383
After updating to B378 and rebooting your phone, check if your phone receives B383 update OTA. If yes, proceed. If not, go to HWFF, download B383 Full-OTA firmware and update via either dload or TWRP method.
3. Update firmware from B383 to whatever later version
After successfully updating your phone to B383, you basically can flash your phone with anything firmware and ROMs built on B380+. I find it unnecessary to update to B386. What I did was that I directly updated from B383 to B394 by following this GUIDE. Since I wanted to try BlueWei 5.7 which is based off B397, I also followed the same guide to update my firmware to B397 before flashing BlueWei ROM.
Now please enjoy all kinds of new ROMs and the fast, revived P9. After this update, my P9 is super smooth (the original firmware and OS was utterly slow and sluggish) and I think I will keep using this phone until it really can't keep up with the hardware requirement of new apps etc.
Hope my guide is helpful!
Nice job to update things and summarize all together. Few comments, though
- Not necessary to go back to c432 b136, to b182 is enough:

- For Nougat, please use Huawei P9 Nougat TWRP:

- For DLOAD method, FullOTA-MF-PV versions should be used
- Besides the two methods listed to initiate DLOAD update, there is also a third one:
'Dial': *#*#2846579#*#*

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.
Has anyone tried it yet?
Don't want to be the first, since I do not feel too comfortable and I am awqy for a few days

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?

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

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.

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?

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:

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.

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

I have tried these packages but they have not worked.
