[Xiaomi Mi CC9 / Mi 9 Lite ROMs, Kernels, Recoverie] tryingtohack:
Today I managed to install this ROM. I went from MIUI 12.5 straight to this ROM using a Windows 10 laptop. In total, it took 5 hours for me, mainly because I underestimated how important preparation was and the lack of good step-by-step installation guide. Here is my help for others who still want to do the same journey.

1. Make sure your boot loader is opened and USB debugging is enabled. This I did 2 weeks ago as you have to wait 168hours after pairing the device with the MI account.

2. Prepare an SD card (FAT formatted). Copy the evolution ROM to the card and insert it in your phone.

ROM A14 as of writing: https://sourceforge.net/projects/ev...xis-ota-uq1a.240205.004-02062105-OFFICIAL.zip

3. Make sure the correct adb and fastboot drivers are installed on your system. If your phone is displayed with a yellow triangle in device manager, it means you have a driver problem that needs to be solved before you can move on. In general, if you install the drivers delivered with the latest MiFlashPro (7.3.706.21) you should be fine.

4. Get the latest adb and fastboot tools from google. More info: https://wiki.lineageos.org/adb_fastboot_guide. Direct link: https://dl.google.com/android/repository/platform-tools-latest-windows.zip. With older adb and fastboot executables installation will not work! It took me 2 hours to figure this out!! I used these versions and did not have a single error as of 19-2-2024: Android Debug Bridge version 1.0.41 Version 35.0.0-11411520, fastboot version 35.0.0-11411520. The files included in the package "minimal ADB install" (or similar) will not work!! get it from Google.

5. When the phone is still running MIUI, it should be displayed in ADB. Open a CMD.EXE and navigate to the directory where you placed the ADB and Fastboot executables. Connect your phone with a REAL DATA(!) USB cable to your PC. Test the correct working of your setup by listing your device: "adb devices". If the list is empty, check again the steps above.

6. Copy the super empty image and the evolution recovery img to the directory of the ADB & Fastboot executables.

Super empty as of writing : https://sourceforge.net/projects/evolution-x/files/pyxis/13/super_empty/super_empty.img

7. Reboot your phone to Fastboot mode by issuing "adb reboot fastboot".

8. Once in this mode, your phone should be displayed with the fastboot driver in the Windows device manager. Test your setup by issuing "fastboot devices". It should display your device.

9. Issue to adjust (dynamic?) partitions: "fastboot wipe-super super_empty.img". It should run without ANY errors. If you get an error, go back and check the steps above. I had many errors because initally I used an old fastboot from 2019...

10. Issue to flash new recovery: "fastboot flash evolution_pyxis-ota-uq1a.240205.004-02062105-OFFICIAL.img" Probably, your need to adjust the name of your recovery file in the command above. It should complete without an error.

11. Issue to reboot to recovery: "fastboot boot recovery evolution_pyxis-ota-uq1a.240205.004-02062105-OFFICIAL.img".

12. Evolution recovery should start. Wipe data partition. Do not wipe system, it may come handy if you need to go backo to MIUI for whatever reason.

13. Finally, install the evolution ROM (zip) by selecting it from the SD card.

Enjoy!
