Hey Guys..
Bought a L29 Mate 8 last week, have been able to unlock, root but now want to install some custom roms..
The installations instructions tell me to go (back) to a stock B1xx rom through the "dload method", and next upgrade to a stock B3xx rom through the "dload" method.
I'm running stock B170, rooted/unlocked right now.
I've loaded a stock B3xx update.app file on my phone, but i'm unable to get the phone to run this update, it either boots normal to system, or when I use vol+/vol-/power it boots into TRWP instead.
Other instructions mention a setting to run update manual going through settings/update but can't find a "manual update"" setting there.
Hope you guys can help me going with this one...
Thanks
You need to flash stock recovery back,use srk tools.

That did the trick, it will "force" manual update now.
Now I run in another problem though, stock rom links for my "NXT-L29C636" are not available, link for C185B170 was still working and the only B320 stock i could find was the one shared by user "bluheart" in his signature "C185B320"
So decided to rebrand the device to C185 with SRK Tool so I would be able to flash these stock roms, first flashed C185B170 through dload method with no problem, and from there tried to flash C185B320 but update does not get passed 5%.
The rom version listed in the device is somehow NXT-C900B170, using the "* # * # 2846579 # * # *" code in dialer confirms phone is "C185 - Africa / Middle East"
Any pointers ?
(edit: tried to reflash C185B170 through download method, also gets stuck @5%)
Thanks
Now in about phone it show C900B170?
Can you get an ota update via updater?
The latest c185B200 so start from this one.
http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1076/g104/v65326/f1/full/update.zip
Or you need to root B170 and change build display and oem info to C185 in srk tools.after this you will be able to dload c185b320

Thanks again for your help...
Used SRK Tools to change ROM version from "NXT-C900B170" to installed "NXT-L29C185B170" in the hope this miss match prevented the update, no luck, also no OTA available.
Thanks for the link, will download this and try to get this going first...
(edit: Changing OEM, SRK Tools read the device as AL-10?, changed to C185, fingers crossed)

Had no luck with the C185 roms, they all got stuck at 5%, decided to rebrand back to C636 and dload the original NXT-L29C636B170 and that worked, so will create a TRWP backup from here to fall back on.
Will give the rebranding to C185 another try later, with the rom you provided (i wonder if i went wrong somewhere with all rom downloads named "Update.zip" I might have mixed something up)
Maybe you/anybody confirm I take the right steps to rebrand to C185 and update to the NXT-L29C185B200 ROM provided.
Using SRK Tool: (current: NXT-L29C636B170/Rooted/Bootloader Unlocked)
1-Install TRWP
2-Change OEM from C636 to C185
3-Change ro.build.display.id=NXT-L29C636B170 to NXT-L29C185170 or NXT-L29C185B200 ?
4- Copy NXT-L29C185B200 "update.app" to device/dload
5- Install Original Recovery
6- Use vol+/vol-/power to apply B200 update
8-Install TRWP/ create Backup
9- Root ?
10- Copy NXT-L29C185B320 "update.app" to device/dload
11- Install Original Recovery
12- Use vol+/vol-/power to apply B320 update
Thanks in advance....

anyone tell where to email for bootloader unlock if website is not recognizing my phone.
updated to B200
Thanks for your help gm, just made a new attempt and now successfully picking up the updates as a C185.
Getting ready for a custom rom
Hi everyone.
I am facing a LOT of troubles with my phone (as stated in this thread).
Anyway now I have again unlocked bootloader, installed TWRP 3.1.1, rooted but I have a strange ROM installed by a service tech shop after the phone became unusable.
The problem is that this ROM does not show an update option in settings so I am stuck at 1st march security patches.
Here attached my actual Build Prop file.
The ROM seems to be a BLN-L21C900B300 (never heard of this and not even found on Firmware Finder) and the fingerprints show a "test keys" rom:
device: HWBLN-H
Display: BLN-L21C900B300
Fingerprint: Huawei/generic_a15/generic_a15:7.0/NRD90M/jslave04010520/:user/test keys
If I try to flash via TWRP a BLN-L21C432B360 (which was my previous stock ROM) it does not work and on TWRP appears the following:
......
write radio image
check_write_data_to_partition
write data error
E; unknown command (errno)
update_huawei_pkg_from_ota_zip: update package from zip failed
updater process ended with ERROR: 7
error installing zip file '/external_sd/update_full_BLN-L21_hw_eu_zip'
I cannot flash the FULL zip file with the core of the ROM but I can luckily flash the data, so I could get back Radio Fm and possibility to install themes....
To make the story short: is there someone who knows what this error is? Maybe I can get a solution.
Moreover: maybe this strange "device: HWBLN-H Display: BLN-L21C900B300 Fingerprint: Huawei/generic_a15/generic_a15:7.0/NRD90M/jslave04010520/:user/test keys" is preventing me to flash?
Changing build prop file can be useful?
Thanks to all.

I forgot to mention: dload not working. Always error.
That's why I think TWRP is the only solution
B300 (at least for the BLN-L24) is the first of two update packages to rollback from Nougat to MM. The first update will take you from the latest firmware to B300 and then the second update will complete the rollback to your device's stock firmware.
dload this package to complete the rollback then do a factory reset and wipe cache partition in stock recovery. After that download and update to the latest firmware and proceed to unlock BL and flash twrp and you should be good to go.

but you mean that I have to downgrade from Nougat to MM again?
And before doing it I have to flash the stock recovery?
My phone was, we can say, flashed in some way by the tech shop to this strange version of Nougat and with the "test keys" fingertips.
With the files you provide I should "dload"?
I do not understand your post.
please explain better.
Thanks.

My phone was, we can say, flashed in some way by the tech shop to this strange version of Nougat and with the "test keys" fingertips. Like I said they did half of the rollback process which is why you are on B300 firmware that you cant find available for download

Download the zip I linked above from Huawei website. Extract the update.app and put it in dload folder on your external SD card and force flash (power vol - vol +). It will flash all the stock images and return your phone to factory firmware android 6.0 EMUI 4.1. It might bootloop after this but booting into stock recovery (power vol +) and perform factory reset followed by wipe cache partition will get you booting. Then you can OTA update to latest firmware and root again.
Well, I will try this weekend. Now the risk to stay without phone during working days is too high
Ah, BTW, thanks for suggestion.

Software install failed.
Incompatibility with current version.
please download the correct update package.
As usual. Huawei sucks. Full stop.

I agree 100%
Since you have nothing to lose right now just try the whole rollback process. Here is the update that the service center used to get your phone to BLN-L21C900B300. You can try flashing that again through dload or skip to trying to flash this. There are two different firmwares listed as the 2nd part of the rollback and you already said the last one I gave you failed so give this one a shot. Let me know how it works out for you:good:

Have you tried the Team MT huawei multitool to flash the images from the firmware? Use the Huawei update extractor tool to get the boot,cust,recovery,system and userdata.img from the firmware you tried to flash and then put them in the unbrick folder in the multi tool. Put phone in fastboot and run the Multi tool and use the unbrick option. I know your phone is not bricked but this way it will flash all 5 images in order through fastboot. You could actually try and flash the most current firmware with this method and avoid having to system update from MM to Nougat.
yes, exactly, I am trying with multitool . another bro suggested me how to do it even if with a slightly different method.
"You need flash the oeminfo via multi tool and then same firmware file for your current version via dload. It should be fixed".
WTF....never sweat so much for a phone. And never had those problems flashing samsung... and I was flashaholic
Yes, I have learned so much about this phone and the flashing/brick/unbrick process in the last 2 weeks.

When I go to multitool "unbrick", it asks for custom.img, but in no update.app of my firmware is present.
Moreover now I just can enter erecovery. It does not boot. I can enter fastboot only. Multitool is now not recognizing the phone. Do you know how to proceed?
I put in dload the firmware .app, but it says "software install failed"
Pheew...I managed to have again that fuc..ng C900B300.
I entered fastboot and repeated the unlock bootloader process. That way the phone got a hard reset and started over. Believe me when I say I tried all the methods I knew.
I think there is something locked somewhere in my partitions (I am not an expert of course) that prevent me to do deep modifications. Now I just can TWRP data but not the core. And again I have no update option. I think I am stuck forever at this stage with 1st march patches and nougat 7.0.
I do not think I will be ever able to have Oreo.
Amen. I am really tired to waste my time with this s**t. Next phone will be again a Samsung or One+. Full stop. Stop chinese brands.
Where are you located, Europe?
Yes
Ok bro I really hope this is it. Full firmware BLN-L21C432B151. I already downloaded it myself and checked with extractor tool it has all the images you need. Since you have fastboot back use the multi tool unbrick again and now that you have all the necessary images cross your fingers it will work.
And I agree with you about the phone. Made up my mind im giving this turd to my sister and getting the OP5T in a few weeks.
Thanks. I will do it this weekend. Today I spent 5 hours to get back my configuration after the hard reset with the apps I use for work. Cannot risk again tomorrow.
In another thread, sashank suggested to change OEM file because probably phone doesn't recognize the firmware I want to install.
It didn't work and lead me to start from scratch with the same strange build.
I will try your method but first I must study better the procedure because I don't want to mess up everything and risking to throw the phone in the garbage (where it belongs in the end...).
Thanks.
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:

https://forum.xda-developers.com/showpost.php?p=72153575&postcount=2
- For Nougat, please use Huawei P9 Nougat TWRP:
https://forum.xda-developers.com/p9/development/twrp-t3565703
- 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#*#*
Project Menu will open, select Software Update
Please... Its for link for download
Developer Settings enabled needed (no need root)
Once you receive the OTA notification, do not update and do not reboot.
Download the OTA and let it remain on the device.
Connect your smartwatch with your Android phone.
Launch the latest Android Wear 2.0 app on the phone.
Tap on the 3 vertical dots, which is the options tab, and select Report Wearable Bug.
It may take a long time to retrieve the log for the last hour. (5 mins aprox)
You will get a notification on the phone saying the report was received.
Now you can directly email yourself to get the log
Upload the .Zip file to there, and apply update
Very thanks in advance, i dont have update

While trying to "unbrick" with stock firmware --> boot loop --> back to internationnal stock --> bad bootloader = sim does'nt work -> trying other firmware -> Working without SIM.
-Solution :
Flash bootloader with 8.1
flash twrp recovery
flash custom rom
Thanks , you sve me!
....

hello i am in your same situation i have bootloader 8.1 plus recovery but every time i install a custom rom he reboots into recovery, which rom did you install?
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 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?

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.

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.
