Debranding Guide China ROM to another variant

Hello guys, i was using bln al10 b172 china firmware. So i decide to change to bll l22 b150, i finally figure out how
the instructions are
1- install "firmware finder" app, search it in google play (by team mt), when installed go to settings of the app (3 dots on the up right app) and enable, installation via system update, a Window appears saying to install huawei firmware finder proxy, press "download addon", and install the apk.
still in settings finally enable "use new firmware base" and "view ota updates".
2- then go to the downloaded addon and open it and follow the instructions...enable wifi proxy...localhost and port 8080...
3- close both apps
4-open firmware finder and find the honor 6x variant ROM you want
i searched BLL-L22 and applied b150 FULL, always apply fullOTA, press the update you want and then " send firmware to updater" (if "download" appears, go to settings and enable those 3 settings i said in the first step) , the firmware finder proxy auto opens, go to settings phone and check updates in default update application Remember keeping those 2 apps opened when you check updates in the huawei update app
5- the selected full ota update appear, download it, in the changelog it says "it will not erase data" BUT IT WILL! so backup first
6- the phone restarts, like a normal update and proceed normal with updating process. I get no errors during flashing
and thats all!, debranding done!
remember having stock recovery and erecovery from huawei!
im pretty sure this will work for any honor 6x variant you have, not only china rom.

Great...thanks buddy.
Few questions-
Does your variant have VOLTE working?
How about the EMUI 5.0 beta for this new version?

Mate, did you get chance to check above or missed anyway.
Once debrandd, arw you facing any issue?
Volte working?
Any other thing or precautions before someone else proceed for the same method?

Hello.
Thanks for the guide but quick question.
Do you have to be rooted or not ?

OK... although I am not sure that I did right, but is tested this.
I have the same version as you, BLN-AL10
I tried with the same BLL-L22C636B150 firmware.
Apparently everything went well, but now my phone says it is a hi6250, BLL-C900B150
Is that OK? How will I know that all my hardware works?

This is a good guide, finally we can get rid of those Chinese bloatwares from the beginning..

Is normal. System is updated perfectly, you can do a factory reset if you want. That not accurate info happens to mostly all firmware finder zips. Hi6250 is the Hisilicon processor the honor 6x (al variants) have. That info is easily edited in the build.prop, is just plain text. You edit and that's all.

Thank you for this info, but... to edit build.prop i need to root the phone, right?
If I root it, I will lose the warranty. furthermore, to root it, I need custom recovery, for that I need the bootloader unlock code.
I cannot get the bootloader unlock code because I get the error message that phone was not used for more than 14 days ...

I can live with the wrong info in about phone... But if you can't you can try unlock the bootloader with DCunlocker and pay 4 eur to get instantly bootloader unlock code.

But I think, that the wrong info will prevent OTA updates for the phone. That would bother me.

I don't think it will cause any issue since the hardware is almost same.

Oeminfo and custom.bin files of Indian version.

Why I can't install EU ROM on my RMX1991? (bought in China)

So, I noticed on the official Realme Software Uptade site that they rolled out eu ROM for Realme X2, tried to install it with stock recovery and nothing really happened, It says installation failed on chinese and that's all. I think that's similar to TWRp error 7, when you re trying to install rom from another phone, but these one are the same phones! WTF, Realme? What's the freaking difference between RMX1991 and RMX1993??? How to flash global rom on RMX1991, that's the main question. Please help.

Try to decript the ozip firmware and edit the updater script. Change the 1993 to 1991.

So there's no point in changing the phone number in ROM s files to rmx1991 from rmx1993. Also, I had an idea to remove the script from ROM's files that check if the phone is compatible with the ROM. Will this work?

You should give a try. First thing to do, its to decript the Global Rom and change the updater script. If you succeed it will now be a flashable rom and use it with unofficial TWRP.

RMX1991 and RMX1993 have different radios as far as mobile data goes, right?
For example, my Chinese (RMX1991) is said to have: B1/B3/B4/B5/B8 + B34/B38/B39/B40/B41
While the 1993 Global Version is said to have Bands 1/3/5/7/8/20/28 (i.e. no 4 but also has 7, 20 and 28)
For me this likely means different drivers.

Its most likely they have different software configuration between 1991 and 1993 but i think they share the same hardware inside. The only way to find out if the firmware is compatible between two is to get the flashing thing done..

You're right, that's the only way. I had xiaomi redmi 5 plus, note 5, note 7, all Chinese versions, but I installed global ROM on every single one without a problem. I hope for Realme it will work. Everything I need is a working TWRP.

"same hardware inside" ??? That would be awesome because it would be great to have LTE Band7 in my country but I was too quick to order the Chinese version before the Global version existed.

Hi folks,
it is not possible to flash unmodified ozip from 1993 on 1991 because there's a version check.
It is not possible to flash unmodified system image because there's partition size difference. All system+bloatware files of 1993 are larger than the system partition size of 1991. So you need to debloat and resize system image before flashing it to 1991. But after flashing boot and resized system from 1993 to 1991 some extra modifications needed. For now I do not know what are they. But for sure this will be resolved, sooner or later.

That's a good thing. Although I was ready to search for someone to sell this phone, I think I will wait some more time for a good solution.

Thank you @yakovpol. @KrinN I was also thinking about selling this phone and ordering the Global version as I was also too fast buying the Chinese version before the Global version was available.
My thinking was "Oh, this is the same thing as Xiaomi. You buy the Chinese version and just install the Global ROM. Yeah right... Boy was I wrong...
Hopefully the developers will find a workaround to flash the Global ROM on to the CN version.
Thank you all for your efforts.

guyz i dont really see why you want to change 1991 to 1993?(literally)

Question Flash Global Rom onto European Model

I have the European model LE2123 and I was wanting to know if I can flash the firmware for the Global model LE2125?
I am having issues activating VoLTE/Wifi and the Global Rom seems to work better for following the guides to activate it on unsupported carriers.
Failing that am I able to downgrade my current European firmware and then cross flash the Global rom? I am on 11.2.4.4 and there is not full download available for the Global rom so was hoping to go back to 11.2.2.2 and then use the local upgrade, would that work?

You can not downgrade like that. Use MSMTool

Can you use that tool to change the region? Aren't you also able to flash the full rom from Fastboot as well?

You can wait til next update for GLO and use local upgrade to switch to it then..
