IR not working on Kingbox k3

Hello, on a Kingbox k3 android 6 version I’ve successfully installed CoreELEC 9.2.0 on a usb key, selectded gxm_q200_2g.dtb from device_tree, copied it in root and renamed in dtb.img.

All is working, video, audio, wifi, bt, lan but not the ir remote. I can only turn on the device from remote and after coreelec is booted the remote stop works and I can use only the included Mini Keyboard wifi.
Obviously the remote work well with the original android.

How can I solve this?

Many thanks, now remote is working.

I can’t attach files, so keymaps are:
