Xiaomi Mibox 3 4k-HowTo switch external/bluetooth/physical keyboard layout/language?

[gessi2000]

Hello,
using a German bluetooth keyboard with my Xiaomi Mibox3 with Leanback Keyboard but as the Onscreen keyboard has German layout the physical keyboard seem to be stuck with English layout!? I know there is an App called "External keyboard helper pro" but this App obviously completely disables the onscreen keyboard which I still want to use with my original Xiaomi remote.

There are no settings for the physical keyboard with the MiBox so how can I change the bluetooth keyboard layout?

One option would be to use HID identification number to create a new .kl file with the key definitions of the keyboard in question.
In some cases you can be lucky and the right file is already present, meaning the default is not used.
But this requires root access or modifying a firmware that you can flash with the changes.
