• 🔓 Unlock the bootloader (bootloader) - a mandatory step before installing custom firmware or obtaining root rights.
• 📥 Install official and unofficial firmware via fastboot flash.

• 🛠️ Perform a rollback to the factory firmware if the smartphone stopped loading.

On Xiaomi smartphones, Fastboot mode is especially important, as the company blocks the bootloader by default. Without it, you can not install TWRP, Magisk or alternative firmware like LineageOS.
