Remote.conf for CSA93 Amlogic S912

I've got a CSA92 Amlogic S912 running Libreelec and my friend got exactly the same. He did someting and now he's remote is not working anymore. I've tried my remote on his box and it's also not working but he's remote is working on my box. I've checked on my box to see if he got a remote.conf file somewhere on his files but couldnt find anything. Also searched myne in all my folders with no luck. Where can i find a remote.conf for this box ? surely it must be somewhere hidden in the files.
