  • 🔄 Updates MIUI: Xiaomi releases firmware for different regions at different speeds, for example, global updates (MIUI Global may come later than Chinese (MIUI China).
  • 🛒 App Stores: The Mi App Store has different apps depending on the region you choose, some of which can be paid in one region and free in another.
  • 📡 Network support 4G/5G: In rare cases, an incorrect region may restrict mobile network performance (e.g., if the device is intended for Asia and is used in Europe).

Advantages of custom firmware:

  • 🌍 Change of the region without restrictions.
