  • press RESET button on the back of the device
  • while keeping RESET button pressed apply power to the device
  • release the button 3 seconds after applying power
  • set your PC to static IP and connect to any of four LAN ports
  • visit with your web browser of choice and upload firmware, router will reboot into OpenWrt automatically

This method is not available, please use OEM easy installation.


FIXME These are generic instructions. Update with your router's specifics.

  • Browse to LuCI Upgrade URL
  • Upload image file for sysupgrade to LuCI
  • Wait for reboot

If you don't have a GUI (LuCI) available, you can alternatively upgrade via the command line. There are two command line methods for upgrading:

  • sysupgrade
  • mtd

Note: It is important that you put the firmware image into the ramdisk (/tmp) before you start flashing.


  • Login as root via SSH on, then enter the following commands:
cd /tmp
wget http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc
sysupgrade /tmp/xxx.abc


If sysupgrade does not support this router, use mtd.

  • Login as root via SSH on, then enter the following commands:
cd /tmp
wget http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc
mtd write /tmp/xxx.abc linux && reboot


Use OEM easy install procedure if bootloader is still intact.
