The main differences:

• 🔄 OTA-Update: Set via the phone menu (Settings) → The phone. → System updates weighing between 50 and 500MB do not affect user data.
• 📦 Full firmware: downloaded manually (weight 1.5-3 GB), requires unlocking the bootloader, erases all data during installation (unless you use special flags).

1. Restore your phone after a major crash (such as a Mi logo hover or a cyclic reboot).
2. Manual installation of the new MIUI version (if OTA is not available for your region or model)
3. Switching to custom firmware (e.g. LineageOS), which requires pre-installing the official full firmware to unlock the bootloader.
