So, after everyone was raving about the 1.35NA version, I downloaded it.  As I always do, I disabled my wireless NIC and connected an RJ-45.  I saved my config to a .gws file.  I uploaded the new firmware.  When I went to reload my settings file, it said it was not a valid file.  I tried multiple times.  I even tried earlier versions of saved config files.  Same thing.  
So, I figured I'd revert to the 1.34NA firmware it was previously on.  It wouldn't take it.  So, I used the router config "system" page and chose "restore factory defaults".  It didn't work.  It still had the 1.35NA.  So, I used the router's reset button.  I held it in for 10 seconds, saw the system lights all blink in unison.  I checked the config page and it was still on 1.35NA.  
So, although the router isn't technically "bricked", it's somewhat frozen in that I can't load any other firmware and can't even reset to factory default.  
Anyway, I just thought I'd give a heads up in case anyone else had the same problem.
