[Solved] Belkin AC 1750 | Unable to find the alt. upgrade guide in OpenWrt wiki mentioned below

My current build: Belkin AC1750DB
Firmware Version OpenWrt Chaos Calmer 15.05.1 / LuCI 15.05-149-g0d8bbd2 Release (git-15.363.78009-956be55)

The site mentions this,

"Some devices lack a sysupgrade image and require a special (and usually a bit more complex) installation procedure that is device-specific. This tutorial won't apply for such devices. Instead follow the custom installation description on the corresponding device page in the OpenWrt wiki."

-- I was unable to find this custom installation description. Please assist.

Target: 188 Belkin F9K1115 v2 (AC 1750 DB) v2 17.01.4 https://downloads.lede-project.org/releases/17.01.4/targets/ar71xx/generic/lede-17.01.4-ar71xx-generic-f9k1115v2-squashfs-factory.bin

This is the current stable firmware release, which includes the sysupgrade...

The upgrade url, 2nd option will work with the Chaos Calmer 15.05.1 GUI?

"The upgrade url, 2nd option will work with the Chaos Calmer 15.05.1 GUI?"

Correct.

thanks, appears to be working!
