Hi Guys,
I was reading some reviews sa rtings.com and I came upon one entry about MU6290 which is basically MU6303 satin na . Ycan enable the bluetooth feature in the firmware using the service menu. Tried and ayun was able to connect my bluetooth headphones and it supports na yung smart remote.
In the service menu, set the following options: (BT Support -> ON, Voice Recognition -> ON, Samsung Smart Control -> ON, BT_AUDIO_ON_OFF -> ON)
