i can't charge my w550i with charger and my headphone also doesn't work but data cable (DCU-60) is working. what is the problem in my mobile?why charger and headphone isn't working? how would i know about bluetooth headset profile? though i apply patch "radio_without_headsets_w550_r4cb020.vkp" but radio isn't working after pressing [search] only shows "no channel found". give me the solution to run my radio at least.
