GUIDE!!!! How to update to EMUI 9 on C432 L09 and L29 - Huawei P20 Pro Guides, News, & Discussion

WARNING: Your data will be erased...
Use these two links:
CLT-L09C432
https://androidhost.ru/1iPC
CLT-L29C432
https://androidhost.ru/1iPD
1. Download the service firmware from the links above for your respective model and extract the "dload" folder from it. It will contain a file called update_sd.zip and two folders - CLT-L09_hw_eu and CLT-L29_hw_eu, each with a respective secondary update package, leave these in the folders and delete whichever folder isn't relevant to your device e.g keep the L09 folder if you have the L09 folder and vice versa.
2. Drag the dload folder to an exFat formatted USB drive and have an OTG cable handy as this phone hasn't got MicroSD support.
3. Plug the OTG cable with the drive in the phone and now go to the phone dialer and dial *#*#2846579#*#* and go to Software Update and then select SD upgrade.
4. EMUI 9 will start installing and your data will be erased after. Note: OEM unlock will be blocked, this is a known bug in EMUI 9 for now and should be fixed in a later update.
5. Enjoy EMUI 9!!!!!!!!!!

This is good solution for the one with locked bootloader, ??
as for the one who already got their bootloader unlocked, i think using flashy tool from Alpha or smohanv thread is better, since it wont erase any userdata, nor it will relock BL
as for bootloader unlocked greyed out, it already fixed on .168
mine is not blocked nor relocked after PIE update.

Hi.
This method works on phones with a locked bootloader?

Yep it works with locked bootloaders. Simple and easy to install.

PS: Please note that this method works with locked bootloaders and no other modifications are required to install EMUI 9

It has to be done on fully stock. You could try on twrp by flashing both primary and secondary update files depending on your model. However doing it through TWRP will lock the bootloader again

Worked great. Thank you

Yeah so on your flash drive keep update_sd.zip and either folder being CLT-L09_hw_eu or CLT-L29_hw_eu

after flash servicesoftware ma BL is locked ?
bc now is unlocked

Next question: Can I download a firmware for C782 via Firmware Finder and install it like that for C432?

[SOLVED from FRD-AL00 to FRD-L09] Soft-bricked honor 8 FRD-AL00

I've an honor 8 FRD-AL00. I've fastboot installed and I'm able to access it. I'm also able to access eRecovery.
I've used SRK Tool to change the oeminfo and custom.bin. After trying to install the official L09 I think I bricked my phone.
Here are the steps I've done:
- Unlock bootloader
- Install recovery 6.0
- Root
- Changed oeminfo and custom.bin
- Reboot and tried to install a stock recovery.img boot.img and system.img (which failed while installing it) from offical L09 UPDATE.APP.
Current status: unable to boot either to recovery or android. what should I do in order to get my phone or install the L09 update or at least something that I can use? I've also used the 3 button trick with the dload/UPDATE.APP in the memory card but the phone doesn't show the loading screen it gets stuck into the huawei logo.
I've then tried to install CM13. I've successfully installed twrp-recovery.img but I'm not able to access it (button + vol down nor button + vol up).
Thanks for the help

Doesn't work, it gets stuck at the huawei logo.
After a couple of tries I was able to get TWRP installed so I'm able to access and modify the filesystem.
I've noticed that, for some reason, my phone has the "default.prop" set up to "ro.product.model=eva" shouldn't this be FRD's or something like that?
Can someone provide me a copy of their /default.prop file so I could compare?

Yes. EVA is another Honor phone. It can be caused of the process you did earlier.

I also have the same mistakes. Help please ...
For now a moment there is no solution for those issues - the only way is to change back to AL00.
Before you do, please install HiSuite, this tool installs all necessary drivers as well.
1) Unlock bootloader and install TWRP: https://forum.xda-developers.com/honor-8/how-to/guide-unlock-bootloader-tested-root-t3443946
2) ROOT: Download SuperSU and flash it using TWRP
2.1) Power off, press volume up + power on
2.2) After TWRP loads, click on Install, select SuperSU zip file you just downloaded and flash it
2.3) Reboot
3) Debrand: https://www.youtube.com/watch?v=JZVsIKtdgV4&t=307s
3.1) This video shows how to debrand P9 but it works on Honor 8 (AL00, AL10, AL09 and AL19)
4) Flash new ROM
4.1) More info about ROMs: https://forum.xda-developers.com/honor-8/how-to/frd-al-00-04-09-10-14-19-differences-t3452924
4.2) ALXX ROM download: https://forum.xda-developers.com/ho...rk-tool-huawei-bootloader-root-t3470823/page3

Hope this helps but please note FRD-L09 ROM running on FRD-AL00 phone is unstable.
Please let me know if you have any other questions.

Update from B131 to B360 (EU Version)

Hi guys,
I bought the Honor 8 a few days ago. It was delivered with B131 (MM/EMUI 4.1). Unfortunately I dont get an update over the phone. So I am looking for a way to get to B360.
I found this method:
############################################
Download Honor 8 Nougat OTA Update for FRD-L09 –
Update.zip
Update_data_full_hw_eu.zip
1) First, download Android 7.0 Nougat ROM for Honor 8 from above and extract it.
2) Now create a folder dload in the root of your SD card and place the update.app file in that folder.
3) Now dial *#*#2846579#*#* from your phone dialer to open a hidden menu.
4) Now click on Project Menu -> Software Upgrade -> SDCard Upgrade.
5) Now select and run the update.
6) Wait until the installation process is complete and then reboot your device.
7) Now extract the second file (update_data_full_hw_eu) from above and save all the files in the dload folder.
8) Now repeat step 3 to 6 again.
9) Done.
#######################################
In the description of this method it says that this is only valid if one wants to update from B320 to B360. As I am on B131 I dont know if i should try this.
Has anybody here succeeded using this method (while coming from B131)? In the description of the method there is nothing mentioned that root or unlocked bootloader is needed... Does this make sense?
Thanks in advance.
Greetz Ric
It should work regardless of the bootloader status. And I think you must be unrooted before trying this.

Hi, i'm sorry I don't really know where to ask.
I'm in B131 too, i'm waiting the OTA, but there is no sim card in my phone. Is that a problem? I don't know if a SIM card is required to get the update.

Flash stock recovery.
For HWOTA8, follow the thread. You need to download FullOTA.
Also with HWOTA8, you will not need to flash stock recovery manually. Basically you flash the zip from TWRP with the provided stock recovery and the three FullOTA update files from Huawei located in a HWOTA8 folder on your external SD card. Once the update is completed, you can then flash TWRP and root again. Same process for every update. Bootloader stays unlocked.

Hi mp187263
Thank you for your reply, I also think updating via hwota8 is better solution, having said that, there are 4 file downloaded from ff 3 of them are with l29 and one is l09.
could u pls advise if i should dl and flash the 3 files all together with hwota8?
many thanks
You should only have 3 files, that are specific to your model. FF gives you the exact download links you need as long as the correct model is selected.
If you can get into the OS, it will be under Settings > System > About phone (example: MHA-L29 with the build number showing the region - ie. C636). Or a better way is to get the FF app and it will show you the model as well as the region. If you cannot get into the OS and your phone has not been rebranded, it will be on a label on the original box. My phone is from China so it came as a MHA-AL00, but was rebranded to MHA-L29C636 (International version). There are also other versions such as C567 for USA and so forth. The files you download have to match exactly what you have, do not flash it if unsure.

Any modified partitions? That would most likely be why, and you'd have to flash FullOTA if that's the case.

Difference between OTA and FULLOTA is that OTA patches existing partitions while full flashes full images. Your data will stay untouched

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.
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.

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 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.

You can..No need. it will just be a command change for this step to C636 and instead of EU the correct one followed by correct firmware flash.
./oeminfo JSN-L21 C432 hw/eu

to anything but chinese, probably. International should be fine. My only worries are that the different firmware wont work with the different hardware.

I did the steps and flashed the L42 files and it worked out fine, and the font was reverted to its original. Then I repeated the steps again and it no longer boots. It can only reach the honor logo and it restarts itself.
