Thanks for the code. Finally one that works for Cox cable remotes. Still more than a little peeved at Roku/TCL for killing the previous working code as I had to literally reprogram 100+ remotes at our hotel, but at least now we won't have dozens of calls every day from guests complaining that the remotes don't work.
Thanks again.
I discovered the auto-program finds a code that works for our ancient RC122 remotes.
1. With the TV on, press and hold OK+TV buttons until blinks 3 times
2. Enter 9-9-1
3. Press play button once and point remote at the TV
4. When the TV powers off, test by pressing the power btton.
5. Press OK again to lock the code.
Each remote model has it's own procedure. Good luck!
