Dear kszag,
I've got Mini MXIII II (S905X). The seller send wrong version.
I tried, your 009 version of LE, and I used this gxl_p212_2g.dtb (rename dtb.img). I found system/etc the remote.conf file and copy to the card root and LIBREELEC > Configfiles folder.
The remote still not working. Under andorid working perfectly.
Could you give me any advice? Here is the remote.conf file, could you check it?
Thank you!
Kind regards,
Cold5
