This is not done for nothing: the manufacturer thus protects the device from:
- ๐ก๏ธ Malware installations (for example, if the phone is stolen and the attacker tries to reflash it)
- ๐ Unauthorized recovery after resetting to factory settings (so that the thief canโt bypass Mi Account)
- ๐ Violations of system stability (castom firmware can conflict with hardwareยป)

- ๐จ Pixel Experience โ firmware with interface and features from Google Pixel
- โก Havoc-OS or Corvus OS โ Firmware with advanced performance settings
Example: On the Redmi Note 10 Pro (sweet), you can install Pixel Experience 13 and get Android 13, even if Xiaomi officially no longer supports the device.
2.Recovery from the "soft brick"
If your smartphone stopped booting after a failed update or reset (called a โsoft brickโ), the unlocked bootloader allows you to:
- ๐ง Install TWRP recovery and recovery of the backup
- ๐ฅ Swipe the official firmware through fastboot without binding to Mi Account
- ๐ Bypass the lockdown FRP (Reset protection if you forget your account information
Without unlocking in such cases, you often have to contact a service center or buy a new phone.
3. Removing the Mi Account binding before sale
If you sell or transfer a smartphone to another person, be sure to unlock the bootloader and remove the account binding.

- ๐ Cannot flash the device through fastboot (Anti-Rollback lock)
- ๐ต Could be facing a blockage. FRP post-discharge
This is one of the most common reasons why customers return used Xiaomi smartphones.

- ๐ฎ Use root emulators (e.g. Dolphin for GameCube)
- ๐ Customize the sound through ViPER4Android or JamesDSP
- ๐ฑ Uninstall system applications (e.g. Mi Browser or GetApps)
- ๐ Optimize battery consumption with Greenify or Battery Charge Limit
Important: Getting root disables the ability to use banking applications (due to SafetyNet), but this can be circumvented with the help of Magisk modules.
5. bypassing regional restrictions
Certain functions MIUI (For example, Google Services or 5G) They can be blocked depending on the region of the firmware:
- ๐ Install global firmware on a Chinese model (for example, on Xiaomi 13 Ultra)
- ๐ถ Unlock support 5G Or VoLTE if they are disabled in your area.
- ๐ Remove pre-installed Chinese apps (e.g. Mi Video or Mi Community)
Example: Redmi K50 Ultra (redmi k50 Ultra) Chinese firmware does not support Google Play - unlock allows you to flash MIUI Global.

| SafetyNet problems | Unlocked bootloader interferes with the work of banking applications (SberBank, Tinkoff) and services (Google Pay). | Use Magisk with Universal SafetyNet Fix or MagiskHide Props Config. |
