Cutting the cable, lets talk options and media setups

I take it the way to do it without a PC is no longer available since ES File Explorer can no longer be installed on the Fire Stick (tried searching with no luck).

How easy is the other process?

I downloaded ES File Explorer the other day, so I think it is still available.

I did it via the PC and it was very easy. Get the IP, use command line structure to push files and install...quite simple...10 mins of work
