@Jilas671 Appreciate your help. Did not expect you to reply so fast.
My bad, I forgot to mention I have T4-R version.
Codes from your json file are new to me and they did not work.
Codes from txt files i've had before. I've exported them from one of remote control android apps. They are not working as well.
I'm using NEC Extended (32 bit) format instead of raw format to store compare and use codes but the logic is the same.
These codes i have and they work:
"6": 0x68040334,(as example: 0x680403FC from txt, 0x680416E9 from json)
"_UNKNOWN_1": 0x68040574,
"VOLUME_UP": 0x68040754,
"VOLUME_MUTE_UNMUTE": 0x68041b52,
"MOVE_LEFT": 0x680415b2,
"PROGRAMME_DOWN": 0x68046B56, (yours, from post from August 31, 2025)
"PROGRAMME_UP": 0x6804659A (yours, from post from August 31, 2025)
and there is HOME button around x680413ba
The 0x6804 part is constant so there is 65536 variants. Already bruteforced 25%.
