As I said, it’s different hardware.The only downgrade would be to take the guts out of your v2 and replace them with the guts of a v1.
I’m sure Rockbox is working on it among their many other projects–which they are doing out of the goodness of their geeky hearts, with little or no help from SanDisk, so you’ll need to be patient.
You can see how they’re doing at www.rockbox.org .
