your handset repair possible in local market..but
if you are know about JTAG then never go in local market..
This is very sensitive and carefully hard work. So in our local market many mobile technician available but they are not enough knowledge. Maximum mobile technician are 10th, 12th pass only. They are not know new technologies. So just they are practical with customer phone. If success then give money. If not success then return, but you are not know what he do with mobile. So maximum mobile technician are permanently destroy customer phone. And also change some parts. If customer says any question then also mobile technician are wrong answer.
