I have a HTC Desire VC with Reliance CDMA. I have OMH card installed and activated, EVDO activated and have subscribed to MOBILENET94 plan. 
This has been working fine from Jan till upto 2 days ago. 
Now net is not working. When I go to settings, under mobile network it says " Turning On" and is stuck there. 
I called Reliance Customer Care and they say my OMH card is not updated. But till 2 days ago it was working fine. 
I wrote to HTC and they say I have to factory reset my device. 
What I want to know is this - 
1) Does it seem like a network / reliance problem or hardware problem? 
2) Do you think a factory reset is necessary? 
3) In case of a factory reset, do I have to activate OMH, activate EVDO and activate Mobilenet again? 
Please advise urgently and thanks.
