If you problem is connecting to network, then make sure modem is detected correctly on not branded connection software. Then make sure APn is correct, network should not be selected manually.

all are fine as device manader showing port (but application port is not showing) and already i mention network comes for 3 sec after update nv by 3rd party utility,

also tried manual search network . as i click network search button searching dialog appear once for a sec and disappear.. and changing band from wcdma to gsm prompt failed error
and tried many connection manager also checked diagnostics in connection manager (generic and branded) , status are ok in all connection manager even sim status is also ok (showing sim message memory, message center no etc..)

it seams some kind of firmware issue because its not creating application port under device manager , and one more thing its not showing hardware ver too
