download which boost you want (full or lite). Install the BadBoy cab, reboot the device. Copy the Audiopara.csv file and paste into the windows folder.
Thats all that works for me. 3 easy steps. install, reboot, copy&paste....ok maybe 4 and a half lol reboot after the paste just to make sure.
which resco are you referring to. (ie. Resco Explorer, resco photoviewer..etc) not sure what TC does tho. maybe another member can explain. However audiopara fix is explained by me.
