Well, I created my own custom_remote (the hard way..ssh to the system; systemctl stop kodi; systemctl stop eventlircd; ir-keytable.......) and rc_maps.cfg, reboot, it didn't work.
I checked my remote key code, it is the same of X96.
Currently I can use a Logitech K400 Touchpad Keyboard, or I can use the TV remote via CEC, but I want to make the IR remote work...
