Guide to Debranding / Rebranding Honor 6X

uditshah · Sep 21, 2017

So I successful managed to rebrand my Indian Honor 6X (BLN-L22) to European Honor 6X (BLN-L21). This enabled me to use frequency band supported by EU version of the phone.

Following are the steps I followed:

1. Unlocked Bootloader : https://forum.xda-developers.com/honor-6x/how-to/how-to-unlock-bootloader-honor-6x-t3535321

2. Flash Custom Recovery:
i. Download TWRP for EMUI 4.1 or EMUI 5.0: https://forum.xda-developers.com/ho...k-recoveries-honor-6x-bln-l21-blnc00-t3632440

ii. In the folder where you have the twrp.img file (name may vary), shift+right click to open cmd prompt.
> adb reboot bootloader
> fastboot flash recovery twrp.img (or whatever is the name of your twrp img file)

3. Download Huawei Multi Tools and backup your oeminfo

4. Download oeminfo flashable zip attached with this post. Currently only EU and India are available. Request other users to share oeminfo of other regions

5. Using Firmware Finder, download the Stock ROM for the desired region. There will be two files, one update.zip file and another region specific file. Download both. Note: Only download Full Ota.

6. Extract the update.zip file and paste the UPDATE.APP file in a folder called "dload" inside an external sd card. Also copy the oeminfo zip file and region specific update zip file to an external sd card

7. Reboot to TWRP and flash oeminfo.zip

8. After oeminfo is flashed. Shutdown the phone and restart by holding vol up + vol down + power. You will enter update page and stock rom will be installed.

9. Once installed, you need to re-install TWRP recovery by following steps 1 and 2.

10. Finally, reboot to TWRP and install region specific update file.

You have now successfully debranded/ rebranded your Honor 6X

***** Edit ******
Uploaded the correct oeminfo file. Thanks @sanjay.rup for notifying the error

Hello,

I have see your zip file and :

oeminfo_HW_EU.zip => updater script => package_extract_file("oeminfo/eu/custom.bin", "/data/custom.bin");
BUT, folder inside zip is => oeminfo\in\xxxxx and custom.bin say "hw/in" (india)

oeminfo_HW_IN.zip => you have forget to remove oeminfo_HW_IN root folder

Conclusion: i haven't test, but i think this 2 zip file will never work ! BUT a BIG thx, i was looking for a indian "oeminfo" file for a friend, i will backup the "asian" oemfile this night, and flash indian oeminfo file manualy with him.

I can re-create the 2 zip file, i have BLN-L21 oeminfo (my phone for EUROPE), AND indian oeminfo "seems" to be good ! but this is your thread

You are right. I realized I uploaded the wrong files. I was using the EU version zip file to create the IN version zip and by mistake uploaded the working file.

Please do upload the oeminfo files you have. It would be super useful for the community

For BLN-L22?
And no need of custom bin?

I used the custom bin file. I have attached the Indian custom.bin file (extract the custom.zip file). If you are flashing using TWRP then you can directly flash the
oeminfo_HW_IN.zip file attached.

Hope this is useful

hi, i think ive made a huge mistake. i tried to modify the EU version of oeminfo by correcting the script ie giving it a correct path (replacing "in" with "eu) in updater script, it got successfully flashed but then the rom failed to install and as soon as the device rebooted system said something like "serious damage has occured" and then it wiped internal memory and locked the boot loader. i tried to install the rom (C185B361) which was working before via dload method but it keeps saying "version not compatible". i have access to fastboot, twrp and i also got backup of my original oeminfo. plz help me thank you

Have you taken twrp backup?
Please restore if you have. Else due to flash, you model number is changed and you are not able to flash the original firmware.
May be you can try the other variant firmware which you flashed

if you have flash indian oeminfo file, you will be able to dload indian rom (C675).

If you flash your backup oeminfo file, you will be able to dload your old region rom file !

Flash the attached oeminfo file using TWRP. It is the correct version of the EU oeminfo. Flash the ROM BLN-L21C10B131. It should work.

Perfect. Can you ask your friend to upload ASIAN oeminfo
