⚠️ Essential Pre-Flash Checklist

Flashing can lead to errors if not done correctly. Complete this checklist to ensure a smooth process. All data will be wiped, so a backup is critical.

    • ✅ Full Data Backup: Save photos, contacts, and files to Mi Cloud, Google Drive, or a PC to prevent data loss.
    • ✅ Charged Battery: Ensure your Redmi Note 5A Prime has at least 60% battery to avoid interruptions during flashing.
    • ✅ Windows PC: The Mi Flash Tool requires a Windows operating system.
    • ✅ Original USB Cable: Use a high-quality USB cable for a stable connection to your PC.
    • ✅ Unlocked Bootloader: Flashing requires an unlocked bootloader. Use the official Mi Unlock Tool (expect a 7-15 day waiting period).

Understanding the Firmware: Types and Regions

Selecting the correct firmware is crucial to avoid bricking your Redmi Note 5A Prime (ugg). The ugg variant (Redmi Note 5A Prime / Redmi Y1) is distinct from the ugglite variant (Redmi Note 5A Lite / Redmi Y1 Lite), which uses a Snapdragon 425 and lacks a fingerprint sensor. Flashing an ugglite ROM on an ugg device can cause a brick.

  • Fastboot ROM (.tgz): A full factory image for Mi Flash Tool, ideal for unbricking or reverting to stock MIUI.
  • Recovery ROM (.zip): Used with custom recoveries like TWRP for installing custom ROMs like Xiaomi.eu.
  • Region Codes:
    • CNXM: China version, optimized for local networks but may lack Google Play services.
    • MIXM: Global version with Google services and multi-language support.
    • EUXM: Xiaomi.eu version, a debloated MIUI ROM with Google services and multi-language support.
