Very good morning, I am new in this field of ST, but I like to research and learn more every day, the son of an external client installed a WWR_600DHP OPENWRT Openwrt firmware router, now they want me to restore it back to its factory state, I hope you can tell me the procedure.

My machine has Windows 10 64 bits installed, I have WinSCP installed and I can access virtual machines with Linux, this information appears on the main page:

OpenWrt | OpenWrt Designated Driver r48624 | Load: 0.01 0.06 0.05
Powered by LuCI (git-16.034.34990-8ae57f6)

Thank you.

It is a very old router (2011 FCC approval), so there may not be many people very familiar with it.

If you can find the OEM firmware, it looks like it supports TFTP flash. https://openwrt.org/toh/buffalo/wzr-600dhp#installation_using_the_tftp_method

OEM firmware that old is certainly not secure in its kernel and 802.11 protocols. Even that more than a year old has at least security issues with 802.11 protocols, if not kernel and third-party applications as well.

Gracias Jeff, voy a seguir el procedimiento, Gracias
