I flashed your firmware today on my r7800 and it seems very well made and really stable. Thanks so much for supporting that great piece of hardware with LEDE.

Only 19MB flash storage are available.
[/quote]Yes, that is true. I have answered that in Netgear R7800 - only 19MB Flash available?
I haven't tried activating that 70 MB partition, but that should be possible in theory, if you build your own firmware.
