This section deals with how you install OpenWrt from a device freshly opened.
http://192.168.1.1/if LuCI is installed.
NOTE: If you are using this to recover from a non working flash, you have to first upload a stock firmware using the same procedure, then flash OpenWrt.
If you have already installed OpenWrt and like to reflash for e.g. upgrading to a new OpenWrt version you can upgrade using the sysupgrade command line tool. It is important that you put the firmware image into the ramdisk (/tmp) before you start flashing.
Note: You need the -sysupgrade.bin file for upgrading.

The bootloader (CFE) has a web interface for uploading firmware images.
Press your reset button while powering up the device, wait ~20seconds, then release the reset button. All LEDs should light.
Your device will be accessible on the
http://192.168.2.1/ address with a very simple webpage where you can upload a new image.
The device will not start a DHCP server, you will have to configure your host to the 192.168.2.x subnet.
Ps. do not try to upload images with TFTP using the flashimage command in your CFE prompt, because it does not works.

there is a problem with the latest trunk - feb 2014 . the router always boot into failsafe - caused by the button config. take a look at https://dev.openwrt.org/ticket/14546
The Bootloader (CFE) is password protected. To abort autoboot you have to either hold the reset button long enough to enter recovery mode or enter
