Hello Mate 20 Users, this is a thread which should help all unlocked users!
Lets dive right into it..


1. Firmware Collection
NOTE: all of the firmwares provided are full ones, no partial ota updates.
last updated: 28.03.19


2. Installing Updates/Restoring to stock
NOTE: I do not take any responsibility what you flash to your device.
I recommend to not downgrade to a previous EMUI version - it might trigger a brick.
This has been tested on my Mate 20 - i upgraded sucessfully to B171 -> B183 -> B188.
  1. Install the app i wrote from here (EMUI Flasher 1.1)
  2. Make sure you are rooted
  3. Select the update_full_base.zip you downloaded (the second firmware file can be ignored)
  4. Tap flash button - device should restart to recovery and install the update

3.1 Rooting (Simple way)
NOTE: you need a unlocked bootloader, those can be bought online for ~30 bucks
  1. Download the recovery ramdisk image i patched in magisk manager here
  2. Flash the image to recovery ramdisk through fastboot
    (Command: fastboot flash recovery_ramdisk recovery_ramdisk.img)
  3. Reboot and keep the Vol+ button pressed to start to recovery mode (Don't worry, it will boot to system anyway)
  4. install latest magisk manager canary build - download here
  5. Enjoy magisk
