well this was bugging me so i went and dug up my ht820 that i had retired since the s9 came out (it has much better audio quality but it never fit right on my big goofy noggin
so it got thrown in a box in the closet)
i charged it for a bit and paired it up and it worked perfectly ... i tried it with various MSVC commands and had no problems ...
sorry if you aready mentioned this but ... what device and rom are you using? mine is in my sig ..
also ... i assume you have MSVC 1.6?
