Hi
How to wipe all sensitive information from OpenWrt device and gift the Router inclusive OpenWrt image to somebody.
I wish to gift soon my old router Netgear R7800 without personal data, but not with stock firmware.
Assuming you used a standard image for the installation (not customized using the image builder):
firstboot -y && reboot
This will erase everything that you have put on your router (configs and user-installed packages) since you flashed it.
If you have customized the image used for install, just grab the standard image from the firmware-selector and install that. Do not keep settings when you do the flash upgrade (uncheck the keep settings box during if using LuCI, or use the -n argument from the commandline: sysupgrade -n <filename>). The device will contain only the default state of OpenWrt when it is done.
