Help amateur.

i have URC-9962. i have succesfully created an upgrade for some of my devices using guide in [Link: hifi-remote.com] .....but when i tried to make an upgrade for my Finlux TV there was problem in protocol name. Keymap-master v8.31 does not support NRC17 protocol what IR recognize in learned signals. What can i do? i have tried couple ready maked upgrades for Finlux TV but they don't work with my tv.

What protocol can i use, or is there another way...

i'm very grateful if someone gives me advise
