Default [Q] Flashing NV Dump file on the device

Hi guys,

Please help me out as i am stuck with the data settings on my phone. When i bought the evo 3d phone configured with reliance, everything was working well. Suddenly, my data network stopped. I contacted the seller and he gave me the new NV dump file stating that the older one is no more useful. He also told me to flash it on my device. He told me that i can do it using cdma workshop.

Can some one explain me the procedure for the same?

Your help is greatly appreciated.
