I have same that. I need to to try add "farfield_play.zapf" of w580 to my w610.
But when I extract FS R8ba024, R6ca001 and R6BC002 it's have only PHF aand VHF. But when I tried connect w580i (R6BC002) with Far. I can saw total 44 .zapf files in phone.
where can I get all 44 files (far can't copy anyfile from db2020)
