Installation method(s):
GUI generic, GUI OEM, CLI generic, Sysupgrade, U-Boot web recovery, see git-commit
Install Comment:
for other supported models, force flash with the tick in OEM Web UI or with "sysupgrade -F -n" in CLI
Recovery method(s):
U-Boot web recovery, see git-commit
Recovery Comment:
U-Boot launches a WEB server on 192.168.1.1 if Reset button is held during power up
Comment:
KNdRt31R4, KNdRt31R34, KNdRt31R33 and probably more models are supported by this OpenWrt image
