Hi! I don't know which version it's fine for your device and the only way to know it it's to flash it yourself, but i don't recommend you to do that.

Rooting with Magisk is fine on 9.1, just read the latest posts from this thread - > https://forum.xda-developers.com/mat...3886967/page27

As for the roll-back, ut should be possible to do it with this tool and an appropriate roll-back firmware (again, firmware version might depend on your cust/brand).

I recommend you to keep an eye and also read this thread - > https://forum.xda-developers.com/mat...te-10-t3722019

B303 is not for A09, it's for C800 which is some jp cust.
Most new fw links are not up yet, and since Huawei decided to name all their firmware the same regardless of model its hard to know which is which :/

Great! Soon i will upload a new version that will also flash the patched Magisk ramdisk_recovery and Magisk Manager (this one will be optional, so those who already have it, can skip it).

Why is root needed? Unlocked bootloader is not enough?

Nope! Well, it can be done without root too, but it would require twrp in that case.
