Please help me BLL-L21 I want rollback :( - Honor 6X Questions & Answers

Hi everyvone. Firstly my English it's not good Im' so sorry. My problem is Huawei GR5 2017 BLL-L21. I can not rollback. I'm updating Firmware Finder Nougat but I want back to MM.
Three button method > I'm getting Software İnstall failed as errors.
Please help me Please I'm waiting for your help

That's because your variant isn't BLN-L21
you have to convert your device and that's a hard process and there's no workaround for it till now

Not working full nougat. Settings » updater is hidden and vol up and power button method » say "your device is booting now" ı dont enter recovery mode.

No you don't need root or unlock bootloader. It's from their website. Be case full though. The firmwares on the website look confusing. Don't flash wrong region firmware or for other model. You better download the packages from here. If you have doubt ask which one you need to download.
Thanks...how to know which region if not indicated in phone

The C209 are not your real CUST cause D305 is a Custom ROM and C209 is a European CUST I dont think you have bought the smartphone in Europe.

Yes, you are right, I purchased in Asia. But now I want to know the real cust for it, because I want to move on marshmallow. Any help?
Which Country did you buy the smartphone?
Maybe there is a Full Rom that you download and manual flash the needed files to downgrade.
I purchased from Dubai.
Normally your should look for a firmewire with CUST C185.
---------- Post added at 08:34 AM ---------- Previous post was at 08:32 AM ----------
Other way is you take a Full 701 ROM extract the CUST and needed files to do a downgrade and flash it.
Do you still have p8 max?

Mexico and USA model

I'm from Mexico and I have FRD-L04 model. It's supposed to be the USA model, but the firmware (in compilation) says: FRD-L04MEXC567B121. The USA model says: : FRD-L04C567B122 (without Mex and with 122)
I have read but I don't find anything about the differences or if they are the same. I hope you can help me because all about Roms and updated talk about the USA model.
MEX is for mexico, it is normal
As long as your device works perfectly in your region and you can get LTE/4G reception you should be good.
the version numbers are similar so there wont be much if anything changed between the two

I tried to change firmware G955N firmware to G955F
but it said it's impossible
What can i do ? Do i have to buy new cellphone?:crying::crying:

I would try too, but we need a pit ...
I highly doubt this is possible although on paper the only difference is the amount of RAM. The G955N is actually the Korean variant so surely you want to stick with that rather than trying to flash a European build either way.

Debrand to enable US LTE bands in Indian Honor 6X (BLN-L22)

I bought BLN-L22 Honor 6X from India and now want to use it in US but it does not work with any network on LTE. Any way I can debrand to use US bands ?
Rebranding is only for software, as for bands, it is hardware related so you can't change anything.
Try willmyphonework.net
BLN-L21 is the Intl. model, I don't think yours will work on US bands
Here are the bands that honor 6x support, 1, 3, 7, 8 and 38

I have read and people have verified with other Huawei phone that the hardware is actually capable of supporting all bands but Huawei locks them based on specific region. It can be unlocked by changing oeminfo and then flashing the rom of that region

In that case, try and tell us if it's true
By rebranding you can use VOLTE ,there is not restrictions and hardware support .
@PalakMi and @venugopalu007, I wasn't able to find oeminfo for BLN-L24 (US version) but I rebranded it to BLN-L21 (EU version) which enabled the wcdma band 2. At least now I have 3g working. This also confirms that hardware supports all bands and that they have just been software locked. Hope someone can provide oeminfo file for BLN-L24 (US version)
