[Huawei Mate 20 X ROMs, Kernels, Recoveries, & Othe] freeza:
Welcome to the Mate 20 X GlobAL00ized project. This ROM's goal is to transform your Chinese AL00 into a global device. This ROM is based on EMUI 9.1 version 9.1.0.120

[size=+2]NOTE: YOU CANNOT DOWNGRADE AFTER UPDATING TO EMUI 9.1. Also, a factory reset is not needed if you are coming from EMUI 9, but if you want to, that's fine.[/size]

Know how to boot into TWRP

EMUI Flasher by @olddroid

EMUI 9.1 (9.1.0.120)

Transformation ROM 2.2

Root with magisk

TWRP image on your PC

Recommendations:

Be decrypted

A factory reset for first time users

Magisk installed to recovery_ramdisk

A backup of your system, preload, product, version, and vendor partitions. Not necessary as erecovery can restore your device, but I thought I'd mention it anyway.

Changelog in the second post

Known Issues:

Google Play store is missing

SetupWizard doesn't work for clean flashes

These will be fixed when L29 EMUI 9.1 is released.

Sometimes the device will refuse to boot with magisk root and get stuck at "your device is booting." Hopefully later magisk versions will fix this. For now simply hold the power button down to reboot and try again. You may need to do this several times. but wait a least a minute before you do.

Installation steps:

First and foremost, backup your device. If you use TWRP or hisuite, go ahead and create a backup with either and backup your internal storage.

Step 1:

Start off by downloading and installing EMUI Flasher below:

Download EMUI Flasher

Step 2:

Download EMUI 9.1 9.1.0.120 AND Transformation ROM 2.2 with either your phone or PC below:

Download EMUI 9.1 version 9.1.0.120

Download Transformation ROM 2.2

Step 3: If you have downloaded EMUI 9.1 and Transformation ROM 2.2 with your phone, skip to step 3.5

Copy EMUI 9.1 (update_full_base.zip) and Transformation ROM 2.2 to your device.

Step 3.5: Now's a good time to disable any magisk modules that may modify or write over system files designed for EMUI 9, they more than likely will not be compatible with EMUI 9.1 and could cause bootloops.

Step 4:

Open EMUI Flasher and select the update_full_base.zip and start the flash.

If you want to remain on EMUI 9.1 official without the Transformation ROM, simply let EMUI Flasher do its thing and you're done. Otherwise, continue on below.

At this point, EMUI Flasher will copy the update_full_base.zip to /data and automatically reboot the phone to nocheck recovery. You will need to pay attention. The flashing process will take less than 3 minutes and when it is done, you will need to boot into fastboot with the phone connected to a PC and the volume DOWN button held.

Step 5:

Once you are in fastboot, open a command prompt/terminal where the TWRP image is located and issue the command "fastboot flash recovery_ramdisk twrp.img"

Step 6:

Issue the command "fastboot reboot" and immediately unplug your device from the computer and begin holding volume UP AND power (release POWER after the display turns on but continue holding volume UP) to get into TWRP.

Note: If for some reason you don't get into TWRP and instead get the boot screen telling you to press volume up for 3 seconds, do that to get to eRecovery, then SHUT DOWN from eRecovery. Once fully shut down, hold volume UP and power until the device vibrates and the display powers on--at this point you may release the power button but CONTINUE HOLDING VOLUME UP until the phone comes on and says it is booting.

Step 7:

Once you are in TWRP, flash Transformation ROM 2.2. The ROM will flash magisk as well but you will still need to have magisk manager if it isn't already installed.

Step 8:

Reboot Recovery from TWRP if you want root, or Reboot System from TWRP if you don't.

Step 9:

Rejoice!
