Recommendation: Keep this 2019 midrange Xiaomi on MIUI builds based on AOSP 10 (API 29) for the best official security and app compatibility; obtain monthly security patches from Xiaomi via Settings → About phone → Check for system packages, and do a full backup before any firmware change. Avoid unofficial releases unless you can restore the stock image and have a tested recovery workflow.
Factory software shipped as MIUI 10 on AOSP 9 (API 28); official major platform support for global variants reached AOSP 10 (API 29) through subsequent MIUI updates. Many later MIUI feature builds (12 / 12.5) remained on that platform level, so expect official upgrades to stop at API 29 for most channels.
Safe upgrade steps: 1) verify exact model and regional codename in Settings → About; 2) create a full backup (local + adb pull + cloud); 3) ensure battery ≥ 60% and stable Wi‑Fi; 4) use the official recovery package with the built‑in Updater app or flash the fastboot ROM with MiFlash for Xiaomi fastboot variants; 5) for MediaTek variants use SP Flash Tool and the correct scatter file. Unlocking the bootloader will factory‑reset the device, so export accounts and keys beforehand.
For later platform builds beyond official support, prefer community ROMs with active maintainers (check XDA/Telegram threads), validated boot images and tracked changelogs. Required steps for custom firmware: unlock bootloader, flash a matching TWRP, make a full Nandroid backup, flash the chosen ROM + GApps separately, then test core functions (radio, camera, biometric). Keep original stock firmware and vendor blobs available for rollback.
Ships with Pie (9) out of the box paired with MIUI 10; an official upgrade to 10 was delivered in 2020, while no official upgrade to 11 was issued by the manufacturer – later releases require third‑party builds.
Use stable MIUI builds that match the phone's platform API level; do not flash ROMs whose base platform (API) is higher or lower than the device currently reports. If you want maximum stability, pick the latest stable MIUI release whose base platform equals the device's reported API level.
Check exact identifiers before any change: via ADB or a terminal app run getprop ro.miui.ui.version.name (MIUI major), getprop ro.build.version.

Example commands: adb shell getprop ro.miui.ui.version.name ; adb shell getprop ro.build.version.sdk ; adb shell getprop ro.product.device.
Typical mapping to use when comparing builds: MIUI 10 builds are commonly based on API 28 (Pie). MIUI 11 builds map to API 29 (10). MIUI 12 and 12.5 builds land on API 29–30 (10 or 11) depending on the specific ROM release. Use the API number, not only the MIUI label, to determine compatibility.
MIUI build strings follow this pattern: MIUI_x.y.z.z.. Example: MIUI 12.0.1.0.PGGMIXM – MIUI 12.0.1.0 (MIUI major/minor), PGG = device code segment, MI = global region. Region suffixes you’ll see most often: CN (China), IN (India), EU (Europe), RU (Russia), MI (global). Match the region and device codename when downloading stable/fastboot ROMs.
Before flashing, verify three values match the ROM file: MIUI major (getprop ro.miui.ui.version.name), API level (getprop ro.build.version.sdk), and device codename (getprop ro.product.device). For a clean, consistent result prefer the fastboot ROM that exactly lists the same device codename and region; use recovery ROMs only if they explicitly list compatibility with the current MIUI build family.
If the bootloader is locked, do not flash fastboot ROMs from other regions – use official recovery updates or unlock the bootloader via the vendor’s approved method first. Always export a full backup and note the security patch date from getprop ro.build.version.security_patch before proceeding.
