Standard OpenWrt Flash Process

For a new device use the standard WebUI to flash the Firmware by using the version for the particular model.

Some devices use a unique way to flash the firmware. If the flash process is different from the generic process you will find the information on the device page. The following describes the standard flash process.

For already OpenWrt flashed devices use the generic version and flash it either via the WebUI or via the CLI with "sysupgrade -n".

If you are not able to connect to the device that runs an old OpenWrt use the Failsave mode (by waiting during boottime till the DMZ LED turns on and then holding the reset pin till the DMZ led starts blinking periodic). In Failsave mode you can access the device via telnet on the IP 192.168.1.1. Then use the command "sysupgrade -n" with an additional parameter for the url to the firmware. For this you need a firmware on a HTTP server.
