this helped me on a tv box S905W with libreelec
put the remote file into the bootable libreelec sd card you have made with win32
and then select one of these remote files
http://mxqproject.com/files/remote-config-file/
put the remote file with the rest of your boot files on the sd card and try to boot the potato
i dont know if you can short pin a le potato?
on my S905W remote file 1 it worked but maybe you have to try more files never had problems with S905X
