R7800 update from 17.04.5 to 18.06.1

Thanks for the replies, guys. I grabbed openwrt-18.06.1-ipq806x-netgear_r7800-squashfs-factory.img and will use atftp following that guide... seems as though the following is the recommended usage of atftp:

% image=openwrt-18.06.1-ipq806x-netgear_r7800-squashfs-factory.img
% atftp --option "mode octet" --option "timeout  60" --verbose --trace -p -l "$image" 192.168.1.1

EDIT: worked flawlessly!

% ssh root@192.168.1.1


BusyBox v1.28.3 () built-in shell (ash)
