Need a flash dump from Linksys ea8100

I have a Linksys ea8100 that's currently hard-bricked and I need a full flash dump of the device to recover. The flash dump will be used for studying its structure and also for salvaging parts, if not all of it.

What version is it, and how would I generate a flash dump? I've got a v2 which I've failed to install OpenWrt on (Failed OpenWrt Flash on Linksys EA8100 v2 - #2 by stringedonbass).
