Current bitrate changed depending what was set in bitrate, default was 180 and I tried 170 too.
Yes I was thinking too that the reason might be the other mods modified firmware, but I was curious to see if I could change easily between mods. But it seems not to be a good idea.
I installed Vasile's mod back and it seems to work normally. But if I want to try NX-KS again I will do the original firmware flash first.
