Micromax MMX310G USB Modem not working.

I have Micromax MMX 310G USB modem working fine till recently on Windows XP. Recently, while browsing I tried to switch from Auto mode to EDGE/GPRS MODE from then onwards the device is displaying "No Device". I restarted the computer and tried to connect. Red light is flashing for few seconds and not recognized. I tried to connect on other computer also. I had the same problem of red light flashing for few seconds and not recognized in that computer also. My warrenty period is over. I have tried repairing windows XP also. Please any one help me.

Try to install Micromax Dasboard manually by downloading. insert the device see the result if working than flash with its firmware otherwise throw it and purchase any unloacked Huawei modem. No device problem is common in Micromax 3G Dongle
