R7800 update from 17.04.5 to 18.06.1

Can someone point me to a doc or step-by-step detailing the update via TFTP process? I'd like the update to be as smooth as it can be.

Not quite sure if this loop works ;- )

The most relevant I found: Netgear R7800 exploration (IPQ8065, QCA9984)

Just wanted to verify it is still contemporary and recommended.

The portion of the code on the router related to booting (including TFTP) are not usually affected by firmware updates. It's generally safe to assume those things regarding booting the router remain the same.

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"

EDIT: worked flawlessly!

% ssh root@

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