Unlocked verizon 9550 GPS not wotking in GSM network

Hi all ,

I have a unlocked Verizon Strom 2 9550 . Currently in GSM network in INDIA , everything is running OK including BIS except GPS . I cannot lock GPS satelite signal or agps through google map . blackberry map can lock AGPS sometimes but not GPS satellite signal .

To activate GPS I did lot of thing like OS reloading from verious vendor from asia . GPSone activation through QPST , fixing GPS at clear sky ( timeout error )etc . But still it not working . Also refresh option is not present in GPS settings option .

Please help how can I activate GPS in my Strom 2 9550 .

Thanks All
