Xiaomi finally rolls out stable Android Pie for the Mi Box S with tons of bug fixes

Xiaomi’s Mi Box S is a nifty gadget that can instantly upgrade your dumb TV into a smart TV. This bargain Android TV box from the Chinese electronics brand is capable of playing 4K HDR content at up to 60fps while also doubling as a Chromecast receiver. The device is now a more appealing prospect thanks to the stable Android 9 Pie update which is now rolling out in batches.


The first public beta of Android Pie for the Mi Box S arrived in November 2019, which also brought in official compatibility for Amazon Prime Video. Xiaomi pushed a few more beta builds afterward and later decided to mark the third beta (build 2231) as the stable Android 9 Pie update during January 2020. However, the company had to halt the update rollout due to various bugs reported by the users.


Xiaomi resumed beta testing earlier this month after a brief pause. Three consecutive beta builds later, the OEM is now confident enough to re-release the stable Android Pie update in the form of build 2604. Coming in at nearly 625MB, the long-awaited OTA update should be available to non-beta participants as well. The cumulative changelog is as follows:

  • Chromecast not working
  • Some apps playback freeze
  • Special H264 decode error
  • BT audio is not sync with video
  • HDMI compatibility
  • Pop sound when STB in standby mode
  • Gboard not working when connecting an external keyboard
  • Fix for CEC not working (from build 2603)
  • System is not stable after back from standby mode (from build 2596)
  • Support more Wi-Fi channel in special area (from build 2596)

Xiaomi has yet to publish the updated kernel source code corresponding to this update in their GitHub repository. In case you need to revert back to Android Oreo (or unbrick your unit), there is a guide available on our forums. For your information, the firmware package for the Mi Box S (code-name: oneday) is not compatible with the original Mi Box, also known as the Mi Box 3 (code-name: once), which is still running Android Oreo.
