Downgrade FW for Root? CLT-104 - Huawei P20 Pro Questions & Answers

This is my first thread so apologies if it doesn't belong here. What I am wondering is if it would be possible to downgrade my P20 Pro to an older EMUI version and from there root my device? I refuse to pay for a bootloader code but am missing my ViperFX and Magisk from my previous phone. Any suggestions are appreciated!

You need unlocked bootloader. Period.

EMUI10 rootable?

Can EMUI10 be rooted with Magisk like EMUI9?
Will the Bootloader stay unlocked after doing the update or did they again integrate some things that make trouble?

EMUI 10 will lock the bootloader and can't be unlocked unless you downgrade to 9.1.
So there's no root if you can't unlock the bootloader.

Unlock BL, root and Roms or Downgrade

Can anyone explain how to unlock the bootloader and rooting works under Emotion UI 9.1.
Since the Huawei has blocked the bootloader codes and no longer releases them to users, the P10 plus has not been developed.
If I have a boot loader code, how do I go about unlocking the boot loader, how do I root my device and is there any way to downgrade?
Because there is the possibility for me to get a boot loader code for my P10 plus, so I would like to ask in advance how the procedure is.
It could be that I probably have to downgrade my device to the older e-motion Ui version so that I can even root and import custom ROMs. Is that right.
Thank you i hope the Comunity can help me.

Mate 10 pro BLA-L09 Should i root with FHMate10Tool.exe or TWRP and magisc?

Hi all, i successfully unlocked my new mate 10 pro, used the DC-unlocker app buying 4 credits to get the bootloader code
and than following the guite on XDA to unlock.
All worked.
NOW i need to root.
I tried to root with the FHMate10Tool.exe and it worked but i forgot to disable the OTA update so i had to reset again.
I dont need the OTA updates or any system update to show up or to install, it will make me loose root.
So should i use the FHMate10Tool.exe and freeze the update service with titanium backup or root with twrp and magisc ?
Thank you !
Hello, I might not be able to answer your question but I am interested in asking you a few questions, what build number was your phone on when you used dc-unlocker?
