WP7700 with AirVantage?

I did not see options where the WP7700 series module was compatible with AirVantage but rather just the WP7702 for the 77xx series.

Would the WP77xx firmware R12 be compatible with the 7700? Or just the 7702?

Or would installing an older firmware release (8, 9, etc.) be a solution? As it does not specify the specific module it’s compatible with (7702, 7700).

It’d be great to get some clarification on the options in the firmware versions:
