it says "folder and file not found", but i copied all needed files to the correct folder on the stick. and if i try the Code
ir-keytable -tit says "no remote device found"
thats my problems with the provided coreelec build.
It looks like you've not yet got the correct dtb.img since it would appear that your ir subsystem isn't been started. Have you tried a few different dtb.img files from the coreelec device tree directory. I would warn you that the device trees changed quite a bit from the ones used in previous LE builds - so simply using a LE dtb probably will have broken functionality.
Go through the ones supplied with CE systematically until one works.
