Okay sounds cool I'll rebrand the question remained is what brand has the latest update?(Please provide a link to .zip update) and the last question is,if I rebrand before I install oreo what exactly happens I turn on my phone and it has a frimware from Africa but its brand is now China!Will that be able to turn on?Or I should use TWRP to install Chinese firmware from SD card.

Since I'm an android developer I need to have multiple os if possible.Has anyone tried this Or any better one?Can I use it in this case?

So I'll go to marshmelo of my region and then rebrand and then install oero the only question left is in the process of rebranding do I need any network connection or it's offline?I don't have stable network and I'm afraid terrible things happen.

I have the firmware finder it found no FULL OTA from marshmelo the first full ota is for nougat.
http://update.hicloud.com:8180/TDS/...2227/f2/full/hw/eu/update_data_full_hw_eu.zip
The links from hicloud says that the files have been deleted.
I don't have a reliable internet connection I rather download zip files then update because I don't want in the middle of the operation things go wrong that's why I didn't try HiSuite.Any live link would be appreciated.
I found NXT-L29BC185B200 live link right now.It's android 6.0.1 I'll go for it tnx.

I download B200 tried to install via dload failed said (incompatiblity with current version ) tried with twrp failed.And I wiped my OS and tried again and failed.And lost my OS.Sort of now it shows me android logo instead of huawie logo and it's stuck on the initial setup of nougat.
https://forum.xda-developers.com/mate-8/general/guide-how-to-downgrade-mate-8-emui-5-to-t3515202
I found this and it says the nougat version must be b500 but mine was b560 and tried to install the rollback and it failed again.I don't know what to do?I need my phone.
Couldn't find any download link of b500 did you do that on your b500 or b560?
If b500 please give me a link of NXT-L29C185B500

Tried again and it didn't give me error this time the point is that it doesn't run on B500 it makes your device B500!

After installing marshmellow the bootloader is locked again!

downgrade /rollback huawei nova 7 5g

Dear all,
hope you are fine and doing well in the current pandemic situation. i have purchased nova 7 5g for work related to replace my broken p30 pro. and i couldn't manage to install google play service on it as the firmware is not supported by googlefier. also the do search a lot for a way to rollback but with no luck to find the suitable rom matching my device. also i contact Huawei service center they said they can only rollback to the latest EMUI10 available before Emui11. huawei firmware finder is not helping as the version i need is removed and the rom link is not working as i try to do it with hisuite proxy app.
my rom details is
JEF-N29-PRELOAD 10.1.1.1(C185R2)​
if any one can help me to find the rom or the way to install googles play service i will be thankful.
thanks in advance
Update:
I manage to go down to 10.1.1.149 but still lzplay app not working.

Just tried rollbacking via hisuite and i think ive hit a wall as well. stuck on emui 10.1 since i think that is the stock emui software the device came on

Hey guys,
I'm not sure of the actual reason, however lzplay will not work on JEF-NX9. After searching a long time, youtube videos of successful installations were using JEF-AN00 or JEF-TN00.

I need huwavi nova 75g jef nx9 downgrade file plz

1. Download and install service ROM .310 via dload method
Download
2. Downgrade to the A7 using HiSuite
3. Install service ROM A7 B142 via dload
Download
4. Now you should be able to use "DC-unlocker" or "hcu-client" (paid services - 4€/$).
The process will erase all your data!

No, you can unlock bootloader for free using this procedure .
But you have to remove the back cover of your phone.
