Hi folks.
Hoping someone might be able to help, though I've spent days reading every post I can find so I think I might be out of luck.
I FOOLISHLY updated the firmware on my parents MiBox3 trying to fix a performance problem and now am hitting all kinds of problems and have definitely made it worse for them.
The hifi receiver won't recognise it, the webcam no longer works on it, Youtube freezes now on occasion.
I want to go back Android 8 if I can, and have read the downgrade instructions that tell you to use Amlogic burning tool - but no joy.

I think I've narrowed the problem down to the fact that the device, rather than showing up per the instructions as MIBOX3, it shows up as "once".
I've tried multiple leads, multiple laptops, I've tried shorting 2 pins inside when powering the thing on - every time it just shows up as "once" and until I can get around that, I wont be able to flash the Android 8 back onto it.
If anyone has encountered this and managed to get past the issue, PLEASE let me know. Desperate here. Otherwise I will be buying them a new player.
Thanks everyone.
once = device codename given by Xiaomi for the Mi Box 3
MIBOX3 = device name
Your logic about the name having to report one over the other seems incorrect.
During an OS upgrade is possible to lose pre-set settings like the device name. When device is brand new the setup app will go through different settings, one setting being the choosing of the device name where you would force MIBOX3 or something else. Easier to believe the device is reverting to codename if the setting pre-set was wiped out.
I believe the problem was you didn't look/search for multiple OTA upgrades after doing the first Android 9 upgrade. Because when getting updates over OTA they usually have to be in a set progressive series of updates. Example a different AndroidTV device of mine, not the MiBox; had 3 updates back to back when it updated to Android 9 from 8.
Do 'Factory_Data_Reset' and go through all the settings again, see if the device will automatically find a new OTA update. Do a couple of reboots, sometimes device will only look for updates after a reboot or power cycle.
MiBox3 has had several mini updates of the Android 9 Firmware since it's launch, the bugs should be less then having to go back to Android 8.
