Installation for fastboot roms (files that end in "-fastboot"):
Download the zip file from our channel
If on Windows, right click on the file, properties, and flag “Unblock”
Unzip the file in a folder on your PC
If you are updating it is recommended to install the MMX-ASA Magisk module (don't press the "reboot" button after installation but manually reboot in fastboot as in the next step)
Reboot your device in fastboot mode (Power+Volume Down) and connect it to the PC
Open CMD as administrator (right click, run as administrator); If on Mac, open Terminal (Applications/Utility)
Type “cd” and copy/paste the address of the folder you unzipped the rom in before, and click enter
If it’s a first installation, on Windows, type windows_fastboot_first_install_with_data_format.bat and click enter; on Mac or Linux, type ./macos_fastboot_first_install_with_data_format.sh or linux_fastboot_first_install_with_data_format.sh and click enter
If it’s an update of a MiuiMix rom installed before, on Windows, type windows_fastboot_update_rom.bat and click enter; on Mac or Linux, type ./macos_fastboot_update_rom.sh or ./linux_fastboot_update_rom.sh and click enter
If you have problems with the phone connection be sure to have installed the fastboot drivers (for Windows you can use the MMX-FastDrive installer) and be sure to have a good USB cable. If the installation process doesn't complete for a phone disconnection simply follow this guide from the beginning.
Wait for the flashing to complete without touching the device or the PC, and without worrying if the terminal seems stuck on one or more operations. At the end of the installation (for both first installs and updates) the device will reboot, and on the terminal you’ll see “Finished”. You can disconnect the device from the PC.
Patiently wait until the device finishes the booting sequence (it could take from 10 to 15 minutes on a first install, 5 to 7 on an update).
Remember that magisk is preinstalled as in all MiuiMiX roms
