Flashing instructions: Depending on the installed firmware, there fastly different methods to flash a MR18. These have been documented on: Note: upgrades from AR71XX are possible, but require the force sysupgrade option. The LEDs has changed since AR71XX. The white LED is now used during the boot and when upgrading instead of the green tricolor LED.
