Very simple to install 9.1 on mate 20 Pro (Lya - L29)
!!! You need a memory card !!!
!!! Be careful this action will relock your bootloader so don't forget your code !!!
!!! Be careful this action will erase your data !!!

1st- download the latest firmware:
In my case C432 (for europe) here:

2nd- copy the "dload" folder on the firmware and past to your sd card

3rd- on your phone you have to write this: *#*#2846579#*#*
choose Software Update
Then Memory card Upgrade

your phone reboot with 9.1

1. Wrong section
2. This is already written everywhere
3. You should put a warning that this will wipe data and re-lock bootloader.
4. OTG should also work.
5. Pressing all buttons while device is off will do the same and trigger update. This is useful for those device that doesn't boot to OS
