How to revert to relatively WiFi stable v2179 Firmware:

If you are running the very latest Mi Box Firmware it will be buggy v2303.

Downgrade to v2179 Firmware is more stable:

Download this and unzip, copy update.zip and the xiaomi_update files to a FAT32 formatted USB stick:

Plug USB stick into Mi Box:

Hold down the big middle Select button and Back at the same time whilst plugging in the Power Cord.

An Auto update should commence if you are successful, you may have to try a number of times to get the remote buttons pressing, power cord insertion timed just right.

If the device is really unstable after that, then it's Factory Reset time:

Android Settings > Storage & Reset > Factory data reset

I might do a smooth 24p video playback DIY if anyone is interested, you use SPMC v16.7.04 and ATV OS system output of 50Hz with Sync Playback to Display enabled in SPMC / Kodi settings.
Use a nice lightweight, snappy Skin like Eminence with SPMC and you are good to go.
SPMC can also give you YADIF2x - SD mpeg2 - high quality Broadcast TV deinterlacing as well.

BTW: I've tried that same 24p / 50Hz setup with Kodi Leia and it's no where near as smooth for video playback vs SPMC.
