Answer: This model left the factory running mobile platform 9 (API 28) and received official upgrades to platform 10 (API 29); for platform 11 or newer you will need a community-maintained build such as LineageOS 18.1/19.

Keep official MIUI releases if you require the highest stability and DRM support; choose a reputable custom ROM only if you accept unlocked-bootloader trade-offs.
Check the current system on-device via Settings → About phone → System update (inspect the MIUI build and system release). From a computer use ADB: adb shell getprop ro.build.version.release and adb shell getprop ro.build.version.sdk. SDK mapping examples: 28 → platform 9, 29 → platform 10, 30 → platform 11, 31 → platform 12. Example output for a device on platform 10 will show "10" from the first command and "29" from the second.
To move to a community image follow a strict sequence: unlock the bootloader with the official unlock tool, create a full backup (TWRP or Nandroid), then flash a custom recovery. Common commands: adb reboot bootloader, fastboot flash recovery twrp.img, fastboot reboot. Install the ROM via recovery sideload or fastboot update packages; obtain files only from trusted sources (official vendor pages, XDA, LineageOS). Maintain a local copy of the stock fastboot/fastboot image to restore in case of failure.
Be aware of functional trade-offs: unlocking and custom firmware can break Widevine L1, impacting banking and DRM-heavy streaming apps. For long-term security keep monthly MIUI updates when available; if extending major platform support is the goal, pick a well-updated community build, verify checksums and signatures before flashing, and keep a tested recovery backup ready. If DRM and app compatibility matter most, stay on official builds; if new platform features matter most, plan for unlocking, backups and possible compromises.
Official Android and MIUI history
Recommendation: Stay on the latest official MIUI Stable build available for your region and install updates only via the system updater after a full backup; use official fastboot/recovery packages from the vendor site when rolling back or performing a clean flash.
How to confirm current OS base and MIUI build:
- Open Settings → About phone → check "MIUI version" and "Security patch level".
- Or via ADB: adb shell getprop ro.miui.ui.version.name (MIUI) and adb shell getprop ro.build.version.release (OS base); adb shell getprop ro.build.version.security_patch for patch date.
Where to find the official release history and downloads:
- MIUI official update pages and the Mi Community changelog archive list all stable, beta and recovery/fastboot ROMs by device codename.
- Use the vendor's firmware repository to download recovery ROMs (.zip) for OTA or fastboot ROMs (.tgz/.tgz extracted) for MiFlash.
- Verify release notes for the build tag and target region (Global, China, India, EEA) before applying.
Interpreting rollout and support status:
- Official updates are usually staged; if an OTA is not visible, check the changelog entry and wait for staged rollout completion.
- Check the last security patch date: if it is older than 12 months, expect official security maintenance to have ceased and plan alternatives.
- Major OS-base upgrades are listed in MIUI release notes; compare your MIUI build number to the archive to see which major bases were applied.
Safe update and rollback practices:
- Backup apps and data (use Mi Cloud and local backup) before any update or flash.
- For recovery updates use the built-in updater app. For full reflash use the fastboot package with MiFlash on a PC.
- To rollback to an earlier official build, obtain the official fastboot ROM for the device codename and use MiFlash with the "clean all" option; unlocking bootloader may be required for some operations.
When official support ends – recommended routes:
- If you need newer OS features or security updates beyond official support, check active custom projects (LineageOS, Pixel Experience) for the device codename and prefer maintained builds with verified maintainers.
- Expect trade-offs: custom firmware can improve OS-base recency but may remove some vendor features (camera optimizations, proprietary services, DRM levels).
- Only install custom builds from trusted sources; verify checksums and follow device-specific installation guides on developer forums.
Quick checklist before installing any ROM:
- Confirm MIUI changelog entry and region tag for the build.
- Record current build string (Settings or adb) and export a full backup.
- Ensure battery ≥50% and a stable USB connection for fastboot flashes.
- Keep a recovery plan: official fastboot ROM and instructions for re-locking the bootloader if needed.
Android version at retail launch
Shipped from stores with Google's 9.0 "Pie" release layered by MIUI 10; the commercial rollout began in August 2019 for the 8-series handset.
To verify on a unit before purchase: open Settings → About phone → check "MIUI version" and the "Base OS" entry (should read 9.0 / Pie on fresh retail firmware). Also confirm the build date and region tag (Global/China) in the MIUI string to avoid units carrying a different regional ROM.
Official incremental upgrades to the 10 (Q) major release were issued in the months after launch; if you need a later Google OS release, confirm the device has received and installed OTA updates. For buyers of pre-owned units, insist the seller applies available system updates and performs a factory reset in front of you.
If long-term platform updates are a priority, check the manufacturer's update tracker for this specific model or consider community-supported custom firmware–otherwise expect stock retail units to have started life on 9.0 Pie with MIUI 10.
