My TrimUI Model Ss came with stock firmware v1.0.7, but MinUI is only able to be installed from v1.0.5. Here's what I did to get it working.
1. Download the v1.0.5 'Factory Recovery' (`Trimui_Factory_Recovery_model_S_dark_V0.105_en.zip`) from TrimUI (very, very slow - mirrored below for convenience)
2. Extract the v1.0.5 zip
3. Remove the SD card from the Model S, connect it to the computer (I used a Windows computer for this) and hold L and R whilst turning it on (you should get a blank screen)
4. Open Device Manager - it should show an unknown device
5. Properties -> Update drivers -> From folder -> Choose the `Drivers/' folder inside the `PhoenixSuit` folder inside the v1.0.5 zip that you extracted
6. Turn off the Model S
7. Open PhoenixSuit, click 'Firmware' and locate the v1.0.5 `.img` file that you extracted
8. Hold L and R whilst turning on the Model S
9. Say 'Yes' to the message that pops up (agree to format the device) and wait for it to install
10. When done, the device should reboot and you'll get a white screen but be able to hear the stock menu music
11. Power off and disconnect the Model S
12. Grab the latest MinUI release zip (MinUI-20210806) from GitHub (link below)
13. Use guiformat (link below) to format the SD card for the Model S
14. Copy the contents of the MinUI zip into the SD card root
15. Insert the SD card into the Model S and power it on
16. You'll still have the white screen, but we can still install MinUI by pressing *left 3 times, A, down 4 times, A, A*
17. Wait for it to install; we can't see progress so I just set a timer for 10 minutes to be safe (has worked twice now so that seems to be enough)
18. Power off the Model S and remove the SD card
19. Download the v1.0.6 'Factory Recovery' (`Trimui_Factory_Recovery_model_S_dark_V0.106_en.7z`) from TrimUI (very, very slow - mirrored below for convenience)
20. Extract the v1.0.6 `.7z` file
21. Open PhoenixSuit, click 'Firmware' and locate the v1.0.6 `.img` file that you extracted
22. Connect the Model S to the computer and turn it on whilst holding L and R
23. Say 'No' to the message that pops up (*do not* agree to format the device) and wait for it to install
24. When it's done, the Model S should reboot and you'll see the stock UI and hear the music
25. Turn off the Model S and insert the SD card
26. Turn on the Model S and you should see MinUI
