Unable to access bootloader after rebranding attempt (AL00 (B225) -> L29 (C636)) - Huawei Mate 9 Questions & Answers

I was running the Ephemeral Mate 9 B225 ROM on AL00. It worked well but I wasn't satisfied with the custom ROM.
So I decided to rebrand to MHA-L29 and run a stock rom.
I started converting my MHA-AL00 (B225) to MHA-L29 using this guide: Link
I've override the L29C636 OEMinfo while keeping the other 5 existing files of the original OEMinfo intact. (See attachment for original OEMinfo files)
I got stuck after restoring the new OEMinfo through TWRP recovery as stated in the guide.
The phone booted up and started the installation of the new firmware. When completed it did a reboot but it never started up again.
Now my phones doesn't respond to input from physical buttons although my PC does recognise a decive as "HI3650". In device manager it also shows up as "Android Bootloader Interface".
Summary of process followed:
1. Bootloader unlocked
2. Instaled TWRP
3. Flashed Ephemeral Mate 9
4. Did a OEMinfo back-up
5. Changed AL00B225 OEMinfo to L29C636 oeminfo
6. TWRP back-up recovery
Next step should be to unlock the bootloader and instal TWRP again but I can't get to interact with the phone at this stage.
Can anyone point to what I did wrong and/or advice me on the next steps I could take?

Use this link mate, always succeed for me, dont need to do anything, just download 3 big files, copy to sdcard and run the bat file.

I can copy those files to the SD-card though a different source.
How can I run the update bat file from the SD when its inserted in my phone?
The phone doesn't respons to ADB and I can't get it to boot in bootloader or recovery. It even doesn't show up as a storage device at my PC (both internal and SD storage).

30-08-2017 14:50 UPDATE: It seems fastboot does recognise the device but adb doesn't. It there a way to use fastboot command to run the bat file or restore the OEMfile back-up. Both are present on the SD-card.
Questions @lemonade747: Does the phone need be be bootloader unlocked and TWRP instaled? I have a slight suspicion that that it both the bootloader got locked and TWRP uninstaled afther the TWRP recovery back-up to L29C636.

Go to download mode (power + volume down), plug the cable and run the bat file from the link I give (remember to download all small link and extract to the same folder), follow its instruction (in the cmd window) to complete the installation. Sorry I cant give your more clearly step. Regarding your question, if your phone has already unlocked BL, it will move to the next step (install the recovery), if not it will ask you put in your passcode to unlock BL then the next step will happen. All thing I said here is in that bat file, very detail.

Thanks for your detailed explanation, but it didn't solve the problem.
The phone is not responsive to go to bootloader mode (power + volume down) and the screen stays black. Fastboot command also dont seem to get it in bootloader mode. I keep getting the error message: (remote: Command not allowed).
The phone won't start up and is not responsive to any input and therefore unable to check status of USB-debugging. (unknown if it is enabled or disabled at this stage).
This stage happend, as explained in the first post, through TWRP back-up recovery with L29C636 OEMinfo files.

There are two method to go to the download mode:
1. Make sure the phone DOES NOT connect to any charger (via cable). Press volume down + Power button and wait at least 10 seconds. If the phone are connecting to charger or laptop, it wont work.
2. Press and hold the volume down button then plug the cable to your laptop (or charger but I prefer laptop cuz we can move to the next step without disruption), it will enter the download mode automatically.
If after trying two method above and still dont work for you, you may need to flash stock rom (including stock firmware) by using E-recovery method.

5-9-2017 UPDATE: I've been unable to solve this issue by myself. The phone is sent for repairs, fingers crossed they will accept it....

(soft)bricked my device. Is there a fix?

Hi all,
I installed the TWRP recovery for my mate 7 - 09 version, with lollipop 5.1. But then I unknowingly wiped something I shouldn't have: I think it was the system folder. No backups were made
My phone keeps starting up to the huawei logo and then reboots\turns off. I can get into fastboot&rescue mode, but that's it. No recovery, no 3-button fix (as far as I know).
The second problem is that I cannot get my device to be recognised by my pc. adb devices doesn't give me any results.
I don't feel like I can install the drivers properly as well. Pherhaps thats the problem? How can I do this? I have a driversetup from a mate7 download, but double clicking it doesnt show any prompts.
Anyone who can help me in any way is more than welcome!

Hey Buddy, here's what you can try to do:
1.) Boot connect your phone to your computer.
2.) Next, boot your phone to fastboot.
3.) Next, open command prompt from the folder where your ADB files are stored.
4.)On CMD type:
fastboot devices
5.) If your device appears then you have 2 options now. You can either:
a.) Flash Stock recovery.img or
b.) Flash back TWRP
6.) If choosing option a.) you can then save stock firmware within dload folder on your external sd card then force upgrade via 3 btn method.
7.) If choosing option b.) you can boot to twrp then either sideload a custom rom or try to save on your external sd and flash

I'll give that a try, thank you. With step 1, you just mean: connect the phone through usb to the computer, right?
When I rooted the phone, I did so on my work laptop, so I am hoping I can get it recognised there, but lets see what happens at home.
EDIT:
Ok, i've typed in fastboot devices, and it gave me one line with a 16-digit code (numbers and letters) some white space and then the word fastboot. What does that mean?
That should meen it recognizes your phone in fastboot mode. Next step is to flash as stated in step 5 that in the instructions.

EDIT AGAIN:
Ok, this is what I did. I downloaded the well known mate7 package, extracted the b119 tools folder and I put the twrp_2.8.7.0_mate7_5.1.img file from this forum (the TWRP for 5.1) inside this folder.
Then, I open cmd inside the folder, and I typed: fastboot flash recovery twrp_2.8.7.0_mate7_5.1.img. This is what happens:
target reported max download size of 471859200 bytes
sending 'recovery'(12644 KB)...
OKAY [ 1.302s]
writing 'recovery'...
OKAY [ 0.455s]
finished. total time: 1.756s
Now, I finally managed to get back into TWRP! I've only got 2% battery though (but I see a + which I think means charging...EDIT: yes, it is on 3% now. Better leave it like this...).
It tells me this:
TWRP has detected an unmodified system partition.
TWRP can leave your system partition unmodified to make it easier for you to take official updates. TWRP will be unable to prevent the stock rom from replacing TWRP and will not offer to root your device. Installing zips or performing adb operations may still modify the system partition.
I decided to swipe, to allow modifications.
So, I've got twrp back! For lollipop. This probably means I have to flash the lollipop rom? I will download the update.zip file next and put it on my sd card (using my pc and a microsd adapter...)
Keep you posted!
Ok, this is not working.
I put update.zip on my sd-card, and tried to install it. This is what I get:
Installing 'sd-ext/update.zip'...
checking for MD5 file...
Skipping MD5 check: no MD5 file found
E:unknown command [errno]
file_getprop: failed to stat
E: error executing updater binary in zup 'sd-ext/update.zip'
Error flashing zip 'sd-ext/update.zip'...
Updating partition details...
...done
EDIT:
I tried to sideload but on my pc I get:
error: protocol fault (no status)
And on my TWRP I get:
You need adb 1.0.32 or newer to sideload to this device.
EDIT:
Updated my adb to 1.0.32 for windows, and rebooted everything. Now i'm at 6% of sideload. Hoping this will work!
EDITn the PC everything seems to go ok, but on my phone it says: E:Zip signature verification failed:1
What should I try next?

I don't advise you to flash lollipop firmware first. It's more prudent to go back to kitkat first as I believe Lollipop needs kitkat as base
1.) Put stock kitkat update.app on dload folder of your memory card. Also make sure you have the LO9 stock kitkat recovery.
2.) With your phone connected to pc, go to twrp and reboot to bootloader.
3.) Once on bootloader open cmd on your tools folder then fastboot flash the stock kitkat recovery.
4.) Once done, fastboot reboot then force upgrade to install stock firmware.
5.) Once you have stock kitkat follow the drill to reach lollipop

Hi, thank you for your advice. I have but one question remaining: what stock kitkat update should I use? And where can I find the right recovery that goes with it?
I've tried several recovery_stock.img I found, and it does take away TWRP, so it might have done the trick. Only problem is that I cannot force upgrade to install whats on my sd-card....The phone keeps turning on (after a long push) and after seeing the logo for a little while, it turns off (short vibration)... Is there another way?

You should flash B137SP03 firmware. You can also refer to this guide:
http://forum.xda-developers.com/mate-7/help/5-1-to-4-4-2-bootloop-t3132888
1.)Prepare the Stock B137SP03 firmware on your SD card
2.)Download the fastboot.zip guide and extract it to a separate folder.
3.) next connect your phone to your computer and go to fastboot mode.
4.) Flash the boot.img and recovery.img you find on that guide.
5.) Once done, do the force upgrade with the B137 firmware.

I've followed the guide you are reffering to. And I flashed the boot and recovery, and managed to get the roll back force installed. But for the life of me, I cannot get my phone to force install the B137 zip. I just can't get into force install mode. Are there tips or tricks? I am holding power up and down, and then press power untill I feel a short vibration. But all it does it show me the huawei logo screen and then shuts down again.
Very frustrating!
EDIT:
ok, I noticed that when my sd-card is not inserted, the phone easily boots into the force install mode. It shows the logo for a couple of seconds, screen goes black and then the force install loads. So this is what I did: insert the sd card half way, press vol up and down, and power on. Then after the logo when the screen goes black, insert the sd-card all the way and when the phone goes to force install mode, it can find the update!
Now installing.... hope this helps someone else out there!
Worked! And I am up and running again! Thank you for saving my mate
I got my Mate bricked and i've been trying to figure out how to solve it. I tried lots of things from different guides, but just an hour ago I found this guide and it worked! I can't tell you how happy I am right now, thanks guys!

Glad to hear both of you guys have your mates up and running again. As long as a phone turns on and is not dead as a brick there's always hope it can be restored
Hi everyone, I have the same problem with my mate 7, i was messing with unlocking bootloader(which I succesfully have done), couldn't get my phone rooted so installed TWRP recovery for Lollipop(which was already installed when i bought the phone). Ended up with soft bricked phone(no OS, no recovery at all).
I tried different tutorials how to fix it, none of them worked(including that one unfortunatelly).
I have taken some pictures to show you what the problem is but cannot post them until reach 10 posts on forum
Basically, i can get into fastboot mode by holding volume down with power button. Windows and Hisuite don't recognise my device but in fastboot mode i can check devices connected. Typing "fastboot devices" i get "P6Q7M14A15008421 fastboot", which i guess is my device indeed.
After that i try flashing boot.img and recovery.img(which are reported OK). Then rebooting with 3 button(vol up and down, power) and Huawei logo screen appears for a bit and goes into white screen saying "rescue mode" and at the bottom: "Error Func NO: 10(FUNC_BOOT_RECOVERY) Error NO:2". Trying rebooting into recovery mode(vol up and power) it shows similar "recovery mode" screen but with different errors: "Error! Func NO:12(FUNC_LOAD_IOM3) Error NO:1".
That's it! It seems like i cannot flash my device successfully for some reason. What Windows version did you guys use?? I tried Win 8.0 and Win 10, maybe i should use older systems? Please help, i had my phone for a week only and broke it(
I can't help you much because I don't have enough knowledge about these kind of things.. I use Windows 7 and from my previous experiences I can say that working with Windows 8 can be frustrating. PS. I bricked my Mate 12hrs after buying it

Sounds like the wrong boot.img or recovery.img has been flashed. May I know what Mate 7 model you have and which Lollipop firmwre version your phone came last with?
Try to obtain boot.img and revoery.img for your lollipop version then flash that via fastboot

My phone mt7-09l, european version 16gb. Came with lollipop 5.1 when I bought it but I think I have formatted it via twrp recovery so it shouldn't matter what boot and recovery version I am trying to flash, should it? I'll extract boot and recovery from b308 today andtry that, see if this works. If not, only thing I can try is using win7 and that's it really, no more possibilities

If you were on Lollipop when everything went sour, you should do what I did, thanks to advice from @blitzkriegger:
You should flash B137SP03 firmware. You can also refer to this guide:
http://forum.xda-developers.com/mate...tloop-t3132888
1.)Prepare the Stock B137SP03 firmware on your SD card
2.)Download the fastboot.zip guide and extract it to a separate folder.
3.) next connect your phone to your computer and go to fastboot mode.
4.) Flash the boot.img and recovery.img you find on that guide.
5.) Once done, do the force upgrade with the B137 firmware.
I used the full steps from the link in there: flashed the right boot and recovery through fastboot. Then I flashed the rollback zip from my sd-card, and then I flashed the B137 zip from my sd-card. I can't tell you more about it, obviously

Been there, done that. Very frustrating! I've tried several things, none of which are probably the right way, but they worked for me. sometimes....
Can you get into stock recovery (vol+ and power)? What I tried several times was wipe cache, and then hold the powerbutton untill my phone turned off. That worked occasionally to get the device totally turned off. Then try to get to force update with your sd-card half way in, and flip it in totally when the logo dissapears and the screen is black. I also tried to shut down the constant starting up by going into fastboot/recovery mode and then holding power down. As long as it takes. Good luck! And hopefully someone can give you proper advice...

Desperate for a Root Method for my P8 Max

Hi all,
Well I love my phone, just love it! BUT having bought it from China, like many I am stuck with the Chinese Model and firmware. Huawei Australia have assisted in unlocking the bootloader, now I am ready to root the phone. BUT, I have not had any luck sourcing a root method for it. Can someone please PLEASE help.
I am desperate as it keeps booting me out of Google Play Services, rendering my Huawei watch useless (ironic huh)
Any help would be appreciated. Email me if you like [email protected]

That sounds to easy, only question, how do I do that? Is there an instruction manual or guidance anywhere?
I have flashed other phones in the past but this one is stumping me.
I have looked for some of these methods only to be completing surveys that inundate me with spam and phone calls, only to be left without the downloads that I needed. Did I mention how much I love my phone?
Thanks again
Michael
Managed to root my phone.. even when I have updated the EMUI to B018, but there was an issue.. I tell you below
Step I follow from Chinese Forum below...
Preparation step :
1. download the tools from
https://www.mediafire.com/?9drsdo2f6hn4j34
2. Extract the content to your local. Note there are two folders :
- Folder 1 is for the tool that contains the TWRP recovery.img and the adb/fastboot tool,
- Folder 2 is for the original recovery
3. Copy the SuperSU zip to your phone (either in internal or external memory of your phone)
Installation step :
Step 0, unlock your bootloader (search around on how to do it)
1. Since I am using mac, somehow I don't need to install any driver, but if you using windows, install all the driver yourself
2. Enable the developer mode in your phone, and after that enable the usb debugging
3. Turn off your phone, and boot to fastboot (in off mode, connect the phone with your PC then press Volume Up and Power Button together)
4. Since now your phone has been connected to the PC, go to that Tool folder in respective of your OS, then overwrite the recovery with TWRP with fastboot command (install custom recovery) *note : for mac just add "./" in every command
- check the whether its connected : fastboot devices
- install TWRP : fastboot flash recovery recovery.img
5. Restart your phone and boot to recovery
- restart : fastboot reboot
- after reboot, turn off your phone
- reboot to recovery : turn on your phone by holding Volume Down with Power button
- Now you are at TWRP
6. Install SuperSU (root)
- Install SuperSU zip that has already been copied to your phone using TWRP (use the Install mode)
7. Reboot the phone
- Use reboot function in twrp
8. Profit
Theoritically the above things works but I have some issues following the above :
- After step 4, after recovery being flashed with TWRP seems like my phone Boot Partition is being overwritten too
- So when I rebooted the phone, it boot to TWRP instead
- So I tried to re-flashed the recovery with the original EMUI rom recovery (go to the folder "2.P8Max_Official_Recovery(For_restoration)" to find the original recovery.img). Also note that in the this folder, the adb and fastboot is only for mac. The one for windows use it in the tools
- This is done by going to fastboot again, then do command : fastboot flash recovery recovery.img
- This time using the original recovery
- Now when I rebooted the phone, it goes to EMUI recovery, then I just clicked restart to system or something
- After this, everything fixed, and I have SuperSU install and phone rooted
You can follow the above, but do it at your own risk, I am not responsible if your phone brick hehehe..

That sounds to easy, only question, how do I do that? Is there an instruction manual or guidance anywhere?
I have flashed other phones in the past but this one is stumping me.
I have looked for some of these methods only to be completing surveys that inundate me with spam and phone calls, only to be left without the downloads that I needed. Did I mention how much I love my phone?
Thanks again
Michael

2. I am not sure how to fastboot.
3. Do I install the file "install this file with install zip from twrp" onto my device? (p8 max)
Again, I thank you.

BTW you will get in a Bootloop if your dont know how to exit I would not root your phone!
Sadly, this does not work for me. I did everything you suggested and in the command window I get nothing
I know the risks ( I think)

Thanks so much for your concern, I know. But I love the phone but need to make it more Android (Google) friendly as it has Chinese firmware which keeps ending any relationship I have with google play services thus rendering the phone useless (almost)
You have been so helpful

I did all you suggested and I could not get it to I renamed the file and as you can see I did a command entry and can see my device which is in faboot and rescue mode (phone unlocked) then I type the command you suggested fastboot flash recovery recovery.img and I get this message
I just do not know what I am doing here
Have u unlocked the bootloader?

The recovery img file link did you downloaded it?
You must download it and but the recovery.img file in fastboot folder
Then rename it to recovery.img.
And open cmd orders from fastboot folder .
Just type
fastboot flash recovery recovery.img
You must download the recovery file into the same folder that you ran your command and in your case "p8 max root". Make sure that the recovery filename is recovery.img instead of some other names.

Hello,
I have twice but now I am stuck on the Huawei logo and powered by Android screen. I can boot into Stock Bootload but no longer TWRP
even though I have reflashed recovery twice. Just chinese language and the EMUI screen with the three options
I think it's time to unroot and flash a new system and do it like i posted, then it will work!

Rebranding Honor 8 FRD-AL10 to FRD-L19 is Easy
I converted two mint FRD-AL10 to FRD-L19 versions yesterday. They have since both taken OTA updates over WiFi. One is at FRDL19C432B360 and the other took an additional update to FRDL19C432B380. I am in the Western United States, the phones know they are here too, but believe they are destined for Europe. When I take a local call, a +1 automatically shows up in front of the number on the call log. When I browse to Yahoo the phone goes to the Yahoo United Kingdom and Ireland home page. The FRD-AL10 phones were both at EMUI 5.0 and Android 7.0 and still at EMUI 5.0 and Android 7.0 after being rebranded to FRD-L19 UK. Everything works including dual SIMs. There is no remnant of Chinese apps, no pinyin characters anywhere. There are absolutely no problems. You do not need to root your phone with this method and you will end up with factory new like European firmware load.
Search these forums and obtain the following files:
Huwaei USB Drivers
DC Unlocker client
Minimal ADB and Fastboot
TWRP-3.1.1-1-frd.img

FRD-L19C432B131-hw-eu-OPU_TWRP_FRD.zip
Format an SDXD memory card. Make sure it is class 10 speed.
Unarchive the rollback package and copy the entire dload folder to the SD card root directory.
Copy FRD-L19C432B131-hw-eu-OPU_TWRP_FRD.zip to the SD card root folder.
Install the Huwaei USB drivers on your PC and phone.
Install DC Unlocker client on your phone.
Install Minimal ADB and Fastboot on your PC.
Copy twrp-3.1.1-1-frd.img into the Minimal ADB and Fastboot folder.
Enable USB debugging on your phone. Enter the system app and tap your build number 5 times and the developer mode becomes available.
In developer mode enable USB debugging and if OEM unlock is there, turn it on. It will likely not be there on the Chinese version, so if you don't see OEM unlock don't worry.
Accept the USB prompts on your phone. Reject communication with Huwaei Suite, Huwaei App, etc., and close them.
Follow the DC Unlocker instructions, buy credit with PayPal, and write down the bootloader code when you see it.
Unlock the bootloader. Open a command prompt in the Minimal ADB and Fastboot folder.
Enter
adb devices
The response should return the serial number of your phone proving USB communication
Enter
adb reboot bootloader
Your phone should now display the fastboot recovery screen
Enter
fastboot devices
The response should return the serial number of your phone
Enter
fastboot OEM unlock [your boot code here]
Your phone will factory reset and is now unlocked. Power down and reboot the phone.
Go to system app, developer, and turn on USB debugging, as before accept USB prompts, and reject and close Huwaei apps.
Open a command prompt in the Minimal ADB and Fastboot folder.
Enter
adb devices
Enter
adb reboot bootloader
The phone should now once again be at the fastboot recovery screen
Enter
fastboot devices
If your phone’s serial number is returned, you have communication.
Now install TWRP.
Enter
fastboot flash recovery twrp-3.1.1-1-frd.img
When the flash writing is done install the SD card and enter
flashboot reboot
Hold down the volume up and power buttons as the phone boots up, you can release the power button at the blue honor screen, but continue to hold down the volume up until you see TWRP.
Tap the install button
Tap Select storage and select the SD card.
Select the FRD-L19C432B131-hw-eu-OPU_TWRP_FRD.zip file and swipe to flash.
When the flashing is done, your oem.info has been changed to Europe.
Select reboot to system.
Hold down volume up, volume down and power simultaneously while it reboots, continue to hold until the phone is in Huwaei erecovery mode.
Erecovery will force the phone to install the update.app file in the dload folder from the sd card. It will take several minutes.
When complete let the phone reboot on its own and hookup WiFi, enable USB debugging and let Huwaei apps hookup. Your phone will appear to be a legitimate European model to the network and will immediately begin to take OTA updates. Your boot loader is locked again, you are not rooted, TWRP is gone and you have a stock UK European version FRD-L19 in your hands.

It looks like you are trying to flash a stock recovery cn.img
If you are at EMUI 5 and I think you are, use the twrp-3.1.1-1-frd.img
It will decrypt the encryption. Other recovery images here cannot decrypt and you must reformat the data partion to use them with EMUI 5. Also, if you root use the SuperSU vesion available from these forums specifically for use with EMUI 5 in the file name. Search for it. Again encryption is involved.
If you can get into fastboot you can fix it. At the bottom of the fastboot screen it should say phone unlocked. If it says locked you will need to unlock the bootloader again.
Always make sure you have USB communication between fastboot and the phone. For some reason Huwaei phones will sometimes disable USB debugging with power down and power up. You need to check each time.

Rollback to EMUI 4.1 C900B300 UK
Search for EMUI 4.1_C900B300, find and use the update.app in this file
Honor%208_Rollback%20Package_FRD-L19_from%20Android%207.0%20EMUI%205.0%20to%20Android%206.0%20EMUI%204.1_C900B300_UK.rar
This is the official Huwaei FRD-L19 rollback package. It rolls your firmware back to the first UK European release of the FRD-L19. It is a full firmware load and will replace everything.
If you get this on your phone, before erecovery is complete or immediately after, your phone will begin taking OTA updates and all will be fine.
If you can get into flashboot, you should be able to get into erecovery, put dload/update.app in the root folder of your sd card, hold volume up, volume down and power throughout bootup.
If erecovery fails the oem info on your phone is not set to europe. Find and install the MT Huwaei Multi-Tool version 7 from the MT forum. Use it to change your oem info and try erecovery again.
The Multi-Tool can do much more without the need to type individual lines of adb and fastboot commands. To run, you execute one of the .bat files in a command window. You will only have two command menu language choices, Russian or English. Choose ru.bat or en.bat accordingly. Try the menu commands without your phone plugged in first.
Thanks friend. I will try id after work. Today in night i tried install rollback(al19 UK) and romC432B131-UK downloaded by hihonor.com. Install by DLOAD folder not work :/ while i pressed three button Phone switch on and stop on (HONOR ON BLUE SCREEN). Install not opened why? Next i tried install only ROM by fastboot. All files install successfull, but recovery.img not work. (maybe file is damaged?) Finally i repeat installed successfull chinese marshmallow b135.
Anyone have good download link working Al19 rom for my AL10?
Sorry for my not good English and very low experience

Hi,
I was on B386 before (Nougat)
Flashing RR-N-v5.8.4 gives this error:
Can't install this package on top of incompatible data. Please try another package or run a factory reset.
Updater process ended with ERROR 7
Any idea ?
Thanks !
PS : This error also prevents me to install B390, B383, B182. Only B360 can be installed from TWRP.

Try to install Lineage 14.1
problem
my p9 i do the things as you saying but it when it goes on fastboot stack on screen your devise is booting now...wont open and at adb says waiting for devise nothing else what to do ?
To get into fastboot mode you keep the phone plugged into computer and hold power and volume down until you get to the white fastboot screen.
There is no need to wait for the battery to drain as you can just force shut down a phone using power + volume down holding.

Hi
I came here because i tried to install miui on my P9 via trwp , somehow it wasnt mountable and after searching the internet i found the solution was to change the filetype.
Sadly i forgot that this would delete my backup, which happened and the miui still wasnt mountable.
I tried your method but after a few miliseconds of the forced update it gets an error and stops.
Or lets say i tried your method while being in trwp recovery mode because otherwise no devices are being detected by adb tool.
i tried to install a p9 stock rom but i cant even mount that one, somehow nothing works.
I seriously dont know what to do anymore.
Try this...
Try to flash downgrade firmware...
Rollback Instructions
Step 1. Download the appropriate rollback firmware
Step 2. Copy the extracted dload folder to the external storage of your phone (micro sd card).
Step 4. Disconnect the USB cable and turn your phone off.
Step 5. Now hold Volume up + Volume down + Power buttons until the installation screen appears.
Step 6. When the phone restarts after completing the installation, your firmware version should now be “B300”.
Step 7. Try to find oldest marshmallow firmware and flash it using same way...
I want to android 6.0 as twrp. How ? Pls

That's the problem, when playing with ROMs you must take carw that you keep OEM Unlocked.
Maybe DC-Unlocker (paid) can help

Help. Phone Relocked. FRP Lock. No OS. No Custom Recovery.

Hello guys,
I had some problems with my Honor 6x L21 so I tried to flash new custom ROM that I didn't like in the end. I tried to revert back and found update.app method. I somehow relocked my bootloader and now tried to install update.app which fails at 5 % and says it is not compatible.
Now, I have erecovery with me that can get nothing after connecting to wifi. No update from SD Card option available.
When I try to unlock bootloader again, it fails.
Also, when I run command 'fastboot oem get-bootinfo' the following lines do come in result:
<bootloader> unlocked
OKAY [0.009s]
Finished.
However, my phone shows Phone Relocked and FRP lock.
Any help guys?
@amannan: I have a US BLN-L24, I was able to use the dload method to roll back to Marshmallow from Nougat. I'm not sure why it sometimes fails at 5%, I think Huawei recently implemented something to cause the update to fail if you haven't passed an online verification check. So basically, no upgrading offline for some of the newer firmwares, someone correct me if I'm wrong. I think it has something to do with Nougat too.
In your case, all hope isnt lost as long as you can access eRecovery and fastboot. What you need to do is find the stock MM packages for your device. This will most likely consist of a small rollback file and a much larger firmware file. Go search Huawei's downloads section on their website until you find what you need, use your model as a reference point. There should also be a PDF file with instructions in it, read it.
For each of the 2 files you get, extract the zips, make a folder called dload on your MicroSD (not internal phone storage). In my case I had to first place the update.app file from the rollback zip into the dload folder, boot to eRecovery (hold volume up and volume down, then hold Power, let let of Power when logo appears but continue to hold the other keys). From there the file will automatically flash. Then I had to extract update.app from the large firmware zip and put in dload, repeat same process again. You should be back on MM.
If either file wont flash then go download Huawei Firmware Extractor. Use it to extract boot.img and recovery.img from the rollback zip's update.app, then boot to fastboot mode while phone is powered off. Plug in a MicroUSB charger into phone then plug other end into PC.
Then:
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot reboot
Make sure to install drivers for the phone first, just install HiSuite on Windows is easiest way. For ADB and fastboot, install '15 seconds adb fastboot" (Google it). If the terminal on your PC says something like "file not found", then either use the cd command (change directory) to move working directory to boot.img/recovery.img location, or move the files to C:\adb.
Once you're back up and booting you can then proceed to bootloader unlock, root, ROM flashing, etc.
Hope this helped!

Dear AnonVendetta, Thank you so much for the help. I was able to use the dload method. I read somewhere that the last firmware version needs to be updated using dload method. I had B361 before it got all messed up so tried that update and it started working.
Also, the fastboot won't flash any img file since the FRP was locked somehow.
Thank you for the help
@amannan: Glad it worked out, you must have already made progress before I posted, your response was too quick.
I do believe you cant flash anything via fastboot if the bootloader is still locked.
I've only owned my Honor 6X for about 2 weeks, I've had to do an emergency recovery several times due to various issues. This is my first Huawei but I've owned many Android devices before, and rooted/custom ROMmed most of them, so I'm just a newbie to Huawei but not Android in general. I'm getting the hang of things.
Good luck!

Yes, dload method is the only way to restore the device in such scenario. If frp is locked then condition is worse as you can not flash anything but only dload will help you. Correct package should be flashed and will succeed.
