HOW TO FLASH EVOLUTION X 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 7. Choose “Wipe” from the main menu, then choose “Format Data“.
Step 8. TWRP will ask for a confirmation. Type “Yes” and hit Enter on your keypad.
Step 9. Once the formatting process is done, go back to main menu of TWRP then choose “Reboot“, then “Recovery“. Your phone will reboot back to the TWRP recovery.
Step 10. Connect your Mi 9T / Redmi K20 phone to your computer using its USB cable.
Step 11. Now copy all the zip files to the phone’s internal storage. Place Xiaomi.eu ROM, the Evo X ROM, Magisk, and Permissive v4 zip files 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 Xiaomi.eu ROM zip file, for instance: xiaomi.eu_multi_HMK20MI9T_9.8.15_v10-9.zip. Tap on it to select it.
Step 14. Do the “Swipe to confirm flash” action. Sit tight and wait for TWRP to flash the zip file.
Step 15. Once done, go back to the main menu then choose “Install” again.
Step 16. Locate the Evo X ROM zip file, for instance: EvolutionX_2.0_MI9T-9.0-20190815-0110-UNOFFICIAL.zip. Tap on it to select it.
Step 17. Do the “Swipe to confirm flash” action. Sit tight and wait for TWRP to flash the zip file.
Step 18. Once done, go back to the main menu then choose “Install” again.
Step 19. Now find the Magisk zip file, for instance: Magisk-v19.3.zip. Tap on it to select it.
Step 20. Do the “Swipe to confirm flash” action. Sit tight and wait for TWRP to flash the zip file. This should finish faster then flashing the ROM file.
Step 21. Go back to the main menu and choose “Install” again.
Step 22. This time, find the Permissiver v4 zip file, in this case is Permissiver_v4.zip. Tap on it to select it.
Step 23. Do the “Swipe to confirm flash” action. Sit tight and wait for TWRP to flash the zip file.
Step 24. Finally, you can now choose “Reboot” then “System“.
Congratulation! You have installed the Evolution X 9.0 ROM (and rooted it) on the Xiaomi Mi 9T a.k.a Redmi K20.
Please remember that the initial booting time usually takes longer than usual.

Please note: The above method was tested using the unofficial build of Evo X ROM by Menphis. His build is based on another work for Redmi K20 Pro. It has some limitation. Hence, please expect some bugs such as the not working Double Tap to Wake (DT2W).
