I would like to install vanilla 19.07.7 (or .8) on my AR750S but I can't find a kernel for 19.07.x (or 18) anywhere.
I tried doing a LuCI-->system upgrade to 19.07.7 squash from the Gl-iNet factory image (3.104, 3.105, 3.201) to no avail.
I tried downgrading to 19.07.7 squash from 21.02.x kernel to no avail.
I have run both the 21.02.x kernels but they lack the ability to save settings. I didn't try the latest snapshots.
What is the correct procedure?
