    This firmware update to android 9 is not stable. A factory reset after the update to pie renders the on screen keyboard not working, does not come up when need to type and to login to wifi there is no ok button to press to accept login details and no onscreen keyboard to enter login details. One needs a usb lan and a physical keyboard to interact with this device now. It a useless device and It should not be pushed for an update by Xiaomi.

    8.1 Oero worked flawlessly with hdhomerun the 9 upgrade ruins this box if you watch live tv with it.

    Trying to figure out how to downgrade this box. I have 2 others on 8.1 that still work fine.
