Thanks for yor replay
but dude,
the handset checked by nokiacare service personel and said that the mainboard shuld be replaced and will cost a huge amount ;considering present value of handset
I would like to learn more about flashing and mobile servicing.quitely i am unknown about technical terms eg:-TUN,PM...etc
I havebeen using diego to hack settings of my phones
please guide me to a forum which is more helpful to me, which includes help for flashing
