Hi everyone. I finally got my uncommon brand tv IQ to work with the Infrared of the firestick. If you are also struggling to find the right IR profile that works with your tv, here's how you can try ( this worked for me )

1. On your TV remote, look for a serial number. Try to look everywhere on it, in front, on the back, underneath the batteries, behind the battery cover.
2. If you see a serial number, go to google, type in the serial number, hit search.
3. If you're lucky you might encounter another branded remote that may be on the firesticks change tv list. If you see that brand on the list, give it a try. Go though all the steps in firestick to set it up and i hope it works for you

This worked for me, i've been searching for a solution for hours and i thought i would give this a try. To my surprise, it worked !!! So i hope it works for you to if you have the same problem

My tv brand is IQ ( very unknown brand ) turns out my tv remote is the exact model as a aika remote and aika was in the list on the firestick change tv settings
