Hi, last night I turned on the mibox with the remote and after a few seconds it appeared the screen for pairing the remote. I pressed home+back as illustrated by the animation nothing. On the background there was a dialog something like "Allow to pair" or something like that, it was partially covered by the pairing screen and it wasn't readable. Tried to use the ir remote from a xiaomi phone, didn't work.
So I unplugged the mibox. At restart it didn't ask pairing, remote not working at all. Changed batteries, still not working. I tried to use a Bluetooth scanner on my phone, I can see that the remote is on, and I can pair it to my phone, pressing the buttons can control the phone.
So I thought there was a bug in the mibox software and I reverted to factory settings. Now it was locked at the first animation screen, where it shows to press home+back to pair, and it can't be skipped with the ir remote. Now, I'm lucky because I have another mibox in another room, so I took that other remote and it paired immediately with the tv
So... seems that the remote is dead? But it can pair and control my phone?
Ps: how to setup the Google account on Android 9? The screen says to tell my android phone "ok Google setup my device" but the assistant is dumb and setups an alarm called "my device". I didn't found a menu for pairing
I got pairing issues as well sometimes.
What usually works is connecting a mouse, getting into settings, unpairing the "old" remote, and then repair from there.
Not sure if it will help in your case but worth a shot.
