Preparation: Unlock bootloader, install TWRP matching device codename, create a complete NANDroid backup, export modem/NV data to preserve IMEI and radio settings, and copy stock fastboot images plus vendor blobs to PC. Use fastboot and adb tools for flashing; verify model ID in About phone before any wipe.
Compatibility notes: Stock firmware shipped on Nougat with MIUI 9 and later received Oreo/Pie-based MIUI releases; official security support tapered off around 2019–2020. Community maintainers still provide builds with security backports and kernel updates, but Widevine L1 or other DRM levels can be downgraded after switching to custom software unless vendor userdata is preserved.
Installation tips: Flash GApps (pico or micro) matching AOSP 10, install Magisk for systemless root and SafetyNet handling, keep boot and vendor partition backups, and follow device-specific threads on XDA or relevant forums for build quirks and known bugs. Do not proceed without a complete backup and clear understanding of bootloader implications.
Original Android Version at Launch
Recommendation: upgrade MIUI to the newest stable build available from Xiaomi before unlocking the bootloader or installing custom firmware.
- Launch configuration: MIUI 9 layered over Nougat 7.1.2; announcement and market release occurred December 2017.
- Factory build examples: MIUI 9.2.x (stable) – typical build strings show MIUI 9.2.1.0 / MIUI9.2.x.x; initial security patch timestamps from late 2017.
- Kernel and vendor blobs were compiled against Nougat-era ABI; many hardware components rely on vendor binaries tied to that base.
- Manufacturer delivered feature-focused MIUI updates rather than frequent base-platform upgrades for this model; long-term base upgrades from Xiaomi were limited.
- Active community ports exist that bring Oreo/Pie-based builds to this handset, but they usually require unlocked bootloader and manual flashing; some device functions (camera, baseband) may need proprietary blobs to work fully.
- Verify current firmware: open Settings > About phone and copy the MIUI build string plus security patch date.
- Create a full backup (Mi Cloud or local), ensure battery >50% and stable connection before any flashing action.
- For official moves: download the correct fastboot or stable ROM from Xiaomi servers and use MiFlash for clean installation; keep the original fastboot package for recovery.
- For third-party ROMs: confirm active maintainer support for this specific model, follow their install instructions, and retain vendor blobs if required for modem/camera functionality.
- If continued security patches are required and no maintained builds exist, consider hardware replacement as the practical long-term option.

Launch release number 7.1.2 (Nougat). Shipped with MIUI 9 Global Stable; initial security patch level dated 2017-12.
If keeping stock firmware, verify build identifier and security patch under Settings → About phone and confirm MIUI channel (Stable or Developer) before installing vendor packages.
For extended support, consider community ports offering Oreo (8.1) or Pie (9.x); these require unlocked bootloader, custom recovery (TWRP), full data and EFS backup, plus strict adherence to model-specific flashing instructions posted on trusted forums.
