HOW TO FLASH PIXEL EXPERIENCE ROM ON MI 9T OR REDMI K20
Step 1. Disable Windows Drivers Signature Enforcement on your computer. We have the detailed tutorial here.
Step 2. Extract Xiaomi ADB Fastboot Driver zip file (miui-ADB-Driver-Installer-v1.4.3.zip) and install it on your computer. This should finish in seconds. Make sure you install it on C:\adb\. This step is necessary to install ADB Fastboot system-wide.
Step 3. Extract the miui-platform-tools_r28.0.1-win.zip on your computer. You’ll get a folder called “platform-tools“. This step is important to make sure you use the latest version of ADB-Fastboot.
Step 4. Unlock the bootloader of your phone. Read the full guide on how to unlock MIUI bootloader officially here. Please be aware that the process requires you to reset your phone. All your data will be lost.
Step 6. Reboot your phone to TWRP recovery mode. Turn off your phone completely then press the Power button and Volume Up button simultaneously.
You may need to do the “swipe to confirm modifications” if this is your first time entering TWRP.

Step 11. Now copy all the zip files to the phone’s internal storage. Place Pixel Experience (zip), Magisk (zip), and Permissive v4 (zip) in the root directory of your phone. The root directory means the upper level or not inside any folder. This will ease you in looking for it.
Step 12. Choose “Install” from the TWRP main menu.
Step 13. Locate the Pixel Experience zip file, for instance: PixelExperience_MI9T-9.0-11082019-1700-UNOFFICIAL.zip. Tap on it to select it.

Possible Issues After Flashing
There is one specific issue on most of custom ROM for Mi 9T/Redmi K20. Some users experience random dark screen after reboot. This sometimes happens during initial booting.
Raulpesch suggests the following workaround:
- Remove the SIM card;
- Find a bright room (sunlight preferred);
- Reboot by pressing power until the logo appears;
- Wait until the screen turns dark (press the power button if you see the clock);
- Swipe down from the top;
- You still won’t see anything yet but the brightness slider is approx 1 cm from the top. Try and swipe it to the right. Keep trying until the screen lights up;
- Disable Adaptive Brightness (Settings > Display > Adaptive Brightness).
Teyodor has simpler solution:
- Force shutdown your phone.
- Restart it again.
- Then disable Pocket Detection in the Settings.
