Changing the Serial No. / Product ID via Sony-PCMA-RE?

[ckrzyzak]

I have a hx-30v and a hx-20v. I took the mainboard out of the 20v and put it in the 30v since they use the same mainboard. I want to maintain the wifi features in the 30v but the mainboard from the 20v doesnt have wifi enabled in the software since that is the only difference between the two cameras. How can I turn this feature on? There are no firmware updates for the 30v only for the 20v.
