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

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

Honor 6x BLN22 Semi Bricked! Help!

Hi! This is my first post and going to be a long one! But kindly excuse me! I need HELP!
I have Semi bricked my Honor 6x firmware (bln-l22, android 6.0, emui 4.1, c675b132, india channel) while trying to manually update it to Nougat which I downloaded from "stechguide.com/honor-6x- b360-nougat-update". I downloaded the Asian version. I accidentally extracted and flashed update_data_full_BLN-L22_hw_spcseas.zip instead of the update.zip first. The update_data_full_BLN-L22_hw_spcseas.zip file got to 100% installed and then went to Huawei eRecovery. Then I couldn't flash the update.zip. I get a software install failed. Also tried to manually flash to stock Rom and other newer update versions of Nougat on SD card again but I get software install failed or Incompatible for this phone. I tried to factory hard reset but this also fails. I can wipe only the cache and reboot which goes again to eRecovery. The eRecovery on wifi does not work either. I looked up booting to safe mode but nothing happens.
After reading a lot on this forum, I tried minimal adb and fastboot. My device in fastboot & rescue mode shows up on minimal adb and fastboot when I type "fastboot devices" command (but adb devices gives no devices/emulator found). It also shows up as Android Phone (Android sooner Single ADB Interface) in Device manager on PC and android drivers is upto date. The Huawei suite loads up but can't connect to it (can't enable hdb).
My phone is boot locked, FRP locked, not rooted (and impossible to enable usb debug) so I can't flash any commands like recovery.img, system.img or twrp and cwm recovery. I always get the remote command not allowed.
Right now, On starting my device, Honor logo shows up, vibrates and goes dark twice then to eRecovery.
All the other combination functions of Power, Vol - and Vol + works.
Please help me restore my Honor 6x to stock or update to Nougat! Thanks a ton!
extract update.zip. Get the UPDATE.APP.
create a "dload" directory to your sdcard. copy UPDATE.APP in this folder
shutdown phone / unplug phone.
hold on VOL + + VOL - + POWER
UPDATE.APP will install. Then shutdown phone. remove UPDATE.APP from dload directory. Extract UPDATE.APP from second zip (smallest one: update_data_full_BLN-L22_hw_spcseas.zip)
copy this new UPDATE.APP into dload folder on sdcard.
Shutdown phone / unplug
hold on VOL + + VOL - + POWER
When install complete, try to boot, if not boot, recovery into recovery and wipe cache / data

Heya! Thanks for the reply.
Can you be more specific about Which ROM to use? The stock ROM or the Newer Nougat Firmware for my phone model?
I have tried the following:
Honor 6X B132 Stock ROM and Honor 6X B320, 330, 360. Yet to try B320, 340 & 342 Firmwares.
I don't remember which one says incompatible, wrong update package or software update failed after 6% installation but bottom line is they all fail to install. I can't do a Hard reset and only wipe cache. I do wipe cache before flashing with SD card dload method but still unsuccesful.:fingers-crossed:

I am not sure! Some people have updated successfully while others are not so lucky and some like me, have messed up!
Unless you are unhappy with your phone performance, I'd recommend not to rollback provided our rollback package is even available to perform that!

Can you kindly send me the firmware download links?
Edit:
I dug deeper into this B360 nougat update and I now know for sure I've tried to flash a wrong update for my Phone wrongly.
The B360 for – [Asian variant] Honor 6X is BLN-L22C636Bxxx which is different from the Indian build – [Indian variant] Honor 6X BLN-L22C675Bxxx.
Am I missing something here?

Thank you in advance.

I think I hard-bricked my phone

I was trying to root my phone but messed up really bad. Before, whenever I bricked my phone, I just used the dload (UPDATE.APP) method to fix it. But now, when I put a UPDATE.APP file in my SD card and press Vol Up+Down+Power. It doesn't go into dload. It just gets stuck into Your phone is booting up.
Now I only have access to fastboot mode and TWRP. Nothing else. TWRP says no OS Installed
What was your build number and what's your model number?
If you can boot into bootloader mode:
1. Download a firmware compatible for your honor from firmware finder for huawei
2. Download and install huawei extractor
3. Extract system.img, boot.img, recovery.img from the firmware
4. Plug your phone to the computer and boot into bootloader
5. Open command prompt and type:
Fastboot flash system system.img
Fastboot flash boot boot.img
Fastboot flash recovery recovery.img
6. Shut down your phone and boot into recovery
7. Perform a factory reset
8. Should be done!

When I bought the phone, it came with FRD-L19C636B360 firmware but it says FRD-AL10 on the back of my phone. So, I don't know what's wrong there. Now that I managed to flash erecovery and go back to stock ROM (FRD-L19C900B131), I'm stuck with EMUI 4.1 and no updates.

Hello,
So it's a rebranded phone, many of imported Honor phones come rebranded by reseller...
I advise you to debrand your phone, a rebranded chinese phone from chinese to europe version can't get working firmware above B380.
To do that, you need to unlock your bootloader and root your device. (Guide: here)
Then you can use this tool to change "vendor/country": Huawei_Multi-Tool_by_Team_MT_v7.1.exe (Avoid v8 update if you can, but if you can't you can launch "v7.1" from v8 interface)

Hold Up wait you must be doing it wrong
Its Power + Vol up or idk
Or maybe make sure its not plugged into anything like the charger or computer if you holding power + Vol up.
That must be the reason why it won't boot to twrp
Hopefully it's solved now

No dude i was doing it right, but something is wrong with the device, the twrp is on the Vol up + Vol down + power now and erecovery is on Vol up + power xD xD
i managed to run C432 on EMUI 4.1 and upgraded it via sw updater into 6.x (twrp appeared in system update xD)
then to 7.X through system update also (twrp did not show now)
then to 8.0.0 via HiSuite and now i am rebranded and on Oreo :3
