This section deals with how you install OpenWrt from a device freshly opened.
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.
cd /tmp/ wget http://downloads.openwrt.org/attitude_adjustment/12.09/brcm63xx/generic/openwrt-SPW303V-squashfs-cfe-sysupgrade.bin sysupgrade openwrt-SPW303V-squashfs-cfe-sysupgrade.bin
→ Basic configuration After flashing, proceed with this.
Set up your Internet connection, configure wireless, configure USB port, etc.
The default network configuration is:

The Speedport W 303V has two buttons. They are Reset and Secure Easy Setup. Here, we merely name the buttons, so we can use them in the above Howto:
|Secure Easy Setup||ses|
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) 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.
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
TCO& when it counts down for autoboot.
