Bricked stock recovery and no flashable update.zip on Mate8 NXT-TL00 with L29 oeminfo

Hey guys,
I was using a NXT-TL00 with Android 7.0 and EMUI 5.0 and I wanted to change to a international ROM with Nougat and EMUI 5.
My current situation:
I unlocked the bootloader.
I can boot into fastboot and flash twrp-3.0.2-0-next.img
I can boot into that TWRP and flash MATE8-TL00-EMUI5.0_B577.zip. (Thanks again, paulcl!)
I can boot into that ROM and use it.
I changed my oeminfo and custom.bin from TL00 to L29 via SRKToolHuawei. Afterwards I had to unlock the bootloader again.
I tried to:
extract various update.zip (update.app inside of the zip) via HuaweiUpdateExtractor_0.9.9.5.
flash the extracted boot.img, recovery.img, system.img via fastboot manually and SRKToolHuawei.
wipe and format data, dalvik, cache, system in- and excluding reboots in every possible variation.
use different TWRP versions.
However:
I can't boot into stock recovery (even after flashing it).
I can't boot into eRecovery.
I can't flash any update.zip oder other ROM besides the one above. Why?
Using eRecovery or stock recovery won't work since I can't boot into it.
TWRP would print this error:
Checking for MD5 file...
Skipping MD5 check: no MD5 file found
mountencrypt: failed to mount /data: No such file or directory
Removing unneeded files...
Patching system files...
Removing empty directorys...

update_huawei_pkg_from_ota_zip: update package from zip failed
Updater process ended with ERROR: 7
Error installing zip file '/external_sd/NXT-TL00C01B575/update.zip'
I can't flash any system.img via fastboot. I would get this error:
fastboot flash system system.img
target reported max download size of 471859200 bytes
sending sparse 'system' 1/6 (452422 KB)...
OKAY [ 13.007s]
writing 'system' 1/6...
FAILED (remote: sparse flash write failure)
finished. total time: 13.045s
What I want:
A fully working TWRP so I can simple flash an update.zip
A working (stock?) L29 ROM with Android 7 or 6 and Emui 5 or 4 and preinstalled GAPPS.
A working stock recovery and erecovery
OTA support
the possibility to lock bootloader when everything else is working
What might help:
A ROM which won't touch the data partition so I can install it trough TWRP.
Maybe there is a way to put the system.img into a flashable zip-file so I can flash the partition via TWRP so there won't be the error message from fastboot. Unfortunately, I have no idea how to do that. An TWRP doesn't allow to flash system.img directly.
BTW:
My current model number is: NXT-L29
My current build number is: "NRD90M test keys"
EMUI-Version 5.0, Android Version 7.0
Thanks for reading through my text. It would be great if there is someone to help me out here!

I already found a solution which is not perfect yet. First, I tried to follow the instructions from
How to install NXT-L29C432B560 (Official) Stock Firmware. (Guide with download links) by sillanwali.
Very helpful for me was post #49. I recommend to read through the first post and then coming back and follow the instructions below.
First, you need:
TWRP 3.0.3 (...3 is for Nougat)
this update.zip
MATE8-TL00-EMUI5.0_B577.zip
The procedure might be too long with redundant steps, but it worked for me. So give it a try:
Unlock bootloader
Flash twrp via fastboot(3.0.3 is for Nougat)
fastboot flash recovery twrp-3.03.img
fastboot reboot​
Boot into TWRP
Copy update.zip and MATE8-TL00-EMUI5.0_B577.zip to SD.
Wipe>format Data>yes
Wipe>Advance wipe >data, dalvik, cache, system
Install this update.zip linked above.
Try to reboot into system. Mine didn't boot into system, but stock recovery and erecovery are now installed. Go on!
Flash TWRP again (since it's overwritten by stock recovery. No worries - you now can now easily flash back stock recovery).
Boot into TWRP.
Copy MATE8-TL00-EMUI5.0_B577.zip to SD Card.
Again, do a full wipe.
Install MATE8-TL00-EMUI5.0_B577.zip.
Reboot into system. It now should work, however it's the Chinese version.
Extract the update.zip and copy update.app to a new created DLOAD folder on the SD Card.
Do a factory reset.
Flash the stock recovery via fastboot (or TWRP). You will get the image by extracting recovery.img of update.app with HuaweiUpdateExtractor.
Reboot into recovery to install the update.app (automatically).
Now you should be on NXT-L29C432B560.
If you want to use the update_data_full_hw_eu.zip or SuperSu follow the instructions in the How-to-install guide.
To be clear, I still have a few problems:
erecovery would boot but when I am trying to restore via wifi I will get the error: "getting package info failed"
Bluetooth and NFC are not working.
Maybe someone has a solution for that?

Root: Stuck at "Your device is booting now"

Hello! I tried to root my Honor 6x (BLN-L21, EMUI 5.0) following the instructions there:
cyberkey.in/how-to-root-honor-6x-100-working/
The bootloader was successfully unlocked.
But when I tried to flash TWRP the process failed and now my phone is stuck on boot :
"Your device has been unlocked and can't be trusted [...] Your device is booting now."
I can get access to recovery and fastboot. I wiped the cache and tried a factory reset but nothing changed, my system won't start and I don't know what to do.
Please help!

if you have the boot backup then restore it.

I don't have any backup. Is there a way to just reset everything? Also I don't know how to connect to the phone anymore since adb won't find the device.

if you cannot find the boot.img
just do a rollback bro

I think that I flashed the wrong files in "boot" and "recovery". Please tell me which files I should flash there.
I used the commands:
.\fastboot flash boot twrp.img
.\fastboot flash recovery twrp.img

The guide from "cyberkey.in/how-to-root-honor-6x-100-working/" is simply wrong when it comes to flashing the twrp recovery. If you really followed this guide completely then you flashed the recovery to the boot partition.
Use "fastboot flash recovery twrp.img" to flash the recovery.
You will still have to flash the boot image to your boot partition then (fastboot flash boot boot.img).

Use fastboot flash recovery twrpname.img to flash the recovery

Ok so basically I need to flash the boot image. However I don't know where to find the stock boot image. I downloaded the so-called "full version" of the stock firmware that I found here: boycracked.com/2017/07/20/official-huawei-honor-6x-bln-l21-berlin-l21-stock-rom-firmware/
However there was no boot.img file inside.
If you could direct me to the proper stock boot.img or send me one, that would greatly help. I had EMUI 5.0 with Nougat 7.0 I believe, phone version BLN-L21.

Thanks. I successfully updated boot.img and and recovery.img, but system won't load, so I might have imported from the wrong STOCK version.
I tried to reinstall a stock ROM using:
fastboot flash system system.img
But I got this error message:

Then I tried to erase the system file with "erase system" and got this error:

I guess that the only option now is to install the files on an external SD card?

I recommend you to download firmware files only from the official honor website or by using the huawei firmware finder(https://forum.xda-developers.com/tools/general/huawei-firmware-finder-team-mt-t3469146)
In this case try to use huawei firmware finder to get the right stock version for your phone. Download these two files: e.g. update.zip & update_full_BLN-L21_hw_eu.zip.
Export the following image files: recovery, system, boot and cust.
The try to flash them:
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash cust cust.img
fastboot flash recovery recovery.img
If flashing a partition via fastboot fails then it is usually because it's the wrong image or just not made for your phone.

Thank you guys, you saved my phone! I eventually managed to flash the files from Nougat update for European Honor 6X BLN-L21C432B360 that I found there: stechguide.com/honor-6x-b360-nougat-update/
Now the phone is working fine.

Hello, could you be more specific about your problem? I'll be able to help you.
Brief Explanation:
From the screen on which you're stuck, press and hold power button for about 10 seconds to forcibly restart your device. when you see the same screen again, immediately press and hold volume up button(for about 3 seconds) to boot to eRecovery.
> Choose shut down option on eRecovery. press and hold vol down button and insert the charging cable to boot to fastboot.
> Press and hold power and volume up button to boot to recovery. (You could do this even from fastboot screen and the screen you're stuck at).

failed (remote: partition length get error) - after update mate 9 to Oreo Beta

Hi my friends
I update my mate 9 to Oreo beta. its cool.
now I want install TWRP Recovery, but in installation through fastboot, I faced with this error:
failed (remote: partition length get error)
please help me. I cannot install recovery.
thanks

where did you get the Oreo beta?

I believe the beta can be downloaded through their web site as a limited tester. My understanding of flashing recovery onto the new Android build is that you'll need a newest version of twrp to work for oreo. Most the time the new updates will mess around with the internal storage space.

The recovery partitions are different in Android O. There is no working TWRP yet.
If you want to downgrade, however, there will be a solution soon.

Here is the solution (forwad)
This is TWRP to Mate 9/Android O, brought to you by FunkyHuawei. This will also work for the Mate 10, Mate 10 Pro, Mate 10 Porsche and other EMUI 8 devices.
It´s just a preliminary build so I can´t promise anything/everything will work! Keep that in mind. I´m not responsible if you brick your device.
DOWNLOAD LINK:
https://drive.google.com/file/d/0B45NCsO2AL_1NEh2aDFLM3JlYkU
It works on the Android O build here:
https://www.reddit.com/r/FunkyHuawei...id_o_beta_for/
and the official European beta.
To install:
First, have Android O running. Unlock the bootloader. Download the twrp image.
Then, run in fastboot mode:
fastboot flash recovery_ramdisk twrp_android_o_mate9_a1.img
Then, reboot holding volume up, and you´ve got TWRP!
Note: With the Android O update, it is no longer possible to flash the recovery2 partition. Furthermore, the names of the partitions have changed. Please keep that in mind, and don´t mess around too much with TWRP, to be sure you don´t brick your system!

great, that worked well. now - with the changed partition table, would you recommend rooting the phone with either of these methods: https://forum.xda-developers.com/mate-9/how-to/guide-how-to-root-mate-9-decrypt-data-t3569986 ?

Dear friend, i have same issue, kindly tell me how to change partition table?

You need to flash to recovery_ramdisk. Fastboot flash recovery_ramdisk twrpo.img

Hi there , so if we want to flash Oreo through fastboot , what could be the commands lines please ?
as ie : fastboot flash boot boot.img or boot_ramdisk / boot_kernel boot.img ? and so on ..
the complete list of commands, would any 1 pass it over here please ? thanks a bunch

Well. You can flash most partitions. If you extract imgs from an oreo update.app you get the complete list (though some can't be flashed, like erecovery_*.img).
If you extract ramdisk (boot ramdisk) from update.app you flash it as fastboot flash ramdisk ramdisk.img. Kernel flashed as fastboot flash kernel kernel.img.
Recovery ramdisk as fastboot flash recovery_ramdisk recovery_ramdisk.img
To extract in Huawei Update Extractor you need to go to settings and disable checksum, it won't extract because something is up with erecovery_ramdis.img (it's misspelled too).

thank you for your reply @ ante0
Something else please .. as I tried and failed to update from MHA-L09-c432198 to Oreo I now get a bootloop error 14 iom3 , I saw on another thread some solutions, which dont work for me as I just cannot boot into twrp because of my battery not charging, even in download / recovery mode... battery three months old... and always working good
What I need to know is how can I either get my twrp saved system back through fastboot or else how can I flash - again only by fastboot mean - the stock firmware of my c432b198 or ...? as i need to flash boot, recovery, cust & system , how can I do so while there is no CUST img in extracted data (seems to be inside the data img itself).
Or else how can do A COMPLETE FORMAT of my internal storage ? the command , any1 i do, give either "not allowed" or partition lengh etc"
any way I can use fastboot to get out of this bootloop iom3 error 14 which don't let my battery charge a little ?
I'm a little much confused and do apology for that. Any help is desesperated needed .

So what is the boot image or the boot partition now called in OREO? I am trying to unbrick my Honor 9 and had Oreo L09-B321 on it before. The only thing I am missing is to successfully flash boot since I am also getting the "partition length error" when I use fastboot boot BOOT.img.

I think ramdisk is the boot partition in oreo, so you have to use fastboot flash ramdisk RAMDISK.img.

Bricked ERROR MODE Func NO : 8 Error NO : 1

Hi,
Yesterday I've tried to rebrand my phone FRD-L09C432 to FRD-L09C10 version. It succeeded and I was in EMUI 4.1.
Then i tried to use hackslash's method to flash android O. While flashing the rom with HuRupdater I've go an error.
Now my phone is bricked in
ERROR MODE
Func NO : 8 (hifi image)
Error NO : 1 (security verify failed)
I've been able to go to fastboot once, and i unlocked bootloader again, but now I can't go back to bootloader anymore.
I've tried every button combination and i left my battery drain to 0% but still no success.
If anyone of you got an idea, I'd be grateful

Did you tried to update your device to Oreo directly from EMUI 4.1. My guide clearly said that you need to flash Nougat package and not Marshmallow one before flashing Oreo.
Regardless, your device is screwed unfortunately and you can't boot your device to fastboot is problematic. I guess you also can't reboot your device to recovery since after you performed the unlock the device has to perform a factory reset and since it's unable to perform it, it has locked you out of fastboot. When I was stuck in this situation, I discharged the battery completely and connected it to PC while holding the volume down button to force it into fastboot. I had to do it several times until it finally worked. After that flash TWRP to your device immediately. Reboot your device to recovery by connecting it to PC and holding the Volume Up button instead. TWRP will allow you to flash a PV package and restore your device.
If you're still unfortunately unable to get your device up and running you have to use DC Phoenix to restore the firmware (it's a paid solution, costs 15 Euros).

When I was stuck in this situation, I discharged the battery completely and connected it to PC while holding the volume down button to force it into fastboot. I had to do it several times until it finally worked. After that flash TWRP to your device immediately. Reboot your device to recovery by connecting it to PC and holding the Volume Up button instead. TWRP will allow you to flash a PV package and restore your device.
If you're still unfortunately unable to get your device up and running you have to use DC Phoenix to restore the firmware (it's a paid solution, costs 15 Euros).

Thank you for the answer.
Btw, can DC Phoenix helps me even when I don't have access to the bootloader? Or do I need first to find a way to go into bootloader

DC Phoenix can help you even if the bootloader is not accessible. For that you have to disassemble your device and follow the DC Phoenix Method 3 aka Test point method to flash board software package and then the complete OS.

HI again, I'm actually in bootloader mode, but flashing TWRP gives me the error FAILED (remote: partition length get error). Do you have any idea on what's causing it ?
EDIT : fastboot flash recovery_ramdisk <your file as usual> worked
EDIT 2 : can't get to reboot in recovery after flashing with that command
EDIT 3 : When I try to reboot to recovery, I get the screen saying "Your device has been unlocked and can't be trusted..." but then I have the error Func NO : 11 (recovery img) Error NO : 2 (load failed!)

What TWRP are you trying to flash? I recommend flashing Honor View 10 one from twrp.me. After you install it and you're able to boot to recovery, ping me back.

Well I won't lie, you're in the exact same situation I was in. However even if your phone doesn't turns on, it's still in fastboot mode. Connect it to PC and check fastboot if it is connected. If not hold down the power button to force a restart and then hold volume down button and reconnect the phone to PC. As soon as fastboot detects your device, use DC Phoenix to again flash the EMUI 401 firmware. This time it will flash successfully.

Idk, I try every button combination but the screen stays black and fastboot isn't connected

Screen didn't turned on for me too. But I guess I was lucky enough that the device was in fastboot mode and I was able to flash the firmware.
Your only choice is the Method 3 now, the Testpoint method.

I simply don't know how to thank you enough. Changed the USB port and my phone is now connected in fastboot mode.
I flashed again with DC Pheonix, it failed again, but my phone restarted and screen turned on. Bootloader was again locked, I unlocked it again and then flashed TWRP from the TWRP Honor 8 Guide.
Now I'm finally back in TWRP, which firmware should I flash ? I'll follow exactly your instructions ahah :laugh:

That's excellent. Before I tell you which firmware to flash, what was your device region before all of this happened.

Okay, what you should do is, flash L09C432 oeminfo.img from TWRP (you can check Huawei MultiTool for the image). After that perform a complete factory from TWRP. Don't reboot your device yet.
Then, flash B394 firmware (FullOTA-MF-PV one) and ensure you flash all the files available for that firmware (two files). Once the flash is complete reboot your device and you're on EMUI 5. You can then use Firmware Finder to update your device to latest package authorised for your device.

Thanks i'll sure try this out ! Just in case, "complete factory," means factory reset not format data right ?

Another question, Huawei Multitool is mainly in russian and i don't understand a single word of it so I'm kind of lost. How should I get the image with that software ?

Try this version http://pro-teammt.ru/projects/hwmt/release/Multi-Tool 8.msi
It's GUI and should prompt you to select language or atleast changing language would be easy.

It seems to be the one I had, anyway i'll do some research bc the GUI is still almost only in Russian even when I select English.
When i click Launch Huawei MultiTool the CMD is in Russian even tho English is selected
EDIT : Nevermind, I found a tutorial I did it.
