If I replace my logic board after water damage, can I clone my existing serial?

Copying to a new thread after this one: https://www.mobileread.com/forums/sh...d.php?t=285434

I'm wondering if my second wash of the device doesn't clear up whatever short or damage has occurred, I could by a replacement logic board from this site: http://www.powerbookmedic.com/Amazon...5-p-95765.html


That replacement would have a new serial number, and whatever else registration related it has.

My worry is that some of those - even though it looks like a reputable site - might be reported as lost/stolen, and would not be able to register to my account.

I would imagine that the site would do a RMA in that case, but it would be nice if I could just tar or dd some folders on my existing device, and clone all of that onto the new one, but I don't know if that is feasible.
