Need Remote Recommendation and Configuration Help

Is there any way I can use my universal remote with Odroid N2 Core Elec?
I have a One For All 5-Device (OARN05G) universal remote that I’ve trained with remotes for Onkyo TX-SR313 AVR and LG 42LV3500 HDTV.
Can I upload config file to work with the One For All remote or either of the others, that I could then train to the One For All?
If so, where do I get config file or how do I create it? and how do I upload it to Odroid N2?
I have a Macbook Pro 2011 on wireless connection and am planning on connecting N2 to DSL modem with ethernet.
If I understand correctly, that should allow me to use built in SMB to connect to N2, right?
