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

Hi mate,

Is it possible to install using USB OTG and software upgrade menu (*#*#2846579#*#*)?
I found this post in Mate-20-pro forum (https://forum.xda-developers.com/ma...-to-update-huawei-mate-20-pro-locked-t3897480). Or that is not working with mate 20.

If I understand this right, you can upgrade your firmware with the *#*#2846579#*#* method on a Mate 20/Mate 20 Pro with a locked bootloader? Just that?

Not quite clear. Which tool did you mean HSTOOL or what? I guess that method requires bootloader unlocking.

Downloaded and check files from Mate 20 Pro that people used with USB OTG method and compared with the one in this thread, they are quite not the same but they have a similar structure.

However, I didn't try to flash my phone because I found that Mate 20 Pro user that flashed firmware from different regions had an issue with Playstore.
