this is really annoying, i connected my tv to the router and started up rusamsung tvcommunicator and when a pop up on the screen asked if i wanted to allow this external remote control ofmy tv, i accidentally said no. now ru samsung tvcommunicator can't even connect to my tv.
now what can i do?
edit, found the remote section in the tvs settings, deleted and re unzipped the ru communicator and its connected again, fingers crossed now
edit2: so i had the filename logic.bin with the extra bin extension that i couldn't see, thx windows. so i removed it, went for the upgrade, it said upgrading, but for literally 7 minutes, then it went back to the main service menu. i turned the tv on and off , hit mute 737 enter and now my logicsw version is 11-11-12. it was 11-06-17 before, so i think it worked. will report back if i have any issue, but for now thanks zoyd and everyone else.
my model number is ps51d550c1n , my panel was df.
