A bit more info about the LG TV setup:
I've also created a firmware profile so I can easily generate a telnet -> LG TV 'gateway', which I'm also going to use to send a wake-on-lan packet to my Kodi machine.
I added a bunch of other profiles now as well:
The most interesting of which is probably the jtag profile which creates a kind-of telnet -> JTAG gateway. Ftp a bootloader onto it, and then telnet in to program the bootloader via JTAG.
