Installation

OEM easy installation

This section deals with how you install OpenWrt from a device freshly opened.

  • Configure your PC to use an IP from 192.168.2.0/24 (not .1)
  • Press and hold reset, power on the device
  • Wait until all leds are lit, then stop pressing reset
  • Upload openwrt-SPW303V-squashfs-cfe-factory.bin file to router
  • Wait for it to reboot
  • Telnet to 192.168.1.1 and set a root password, or browse to 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.

Upgrading OpenWrt

generic.sysupgrade

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.

LuCI Web Upgrade Process

Terminal Upgrade Process

  • Login as root via SSH on 192.168.1.1
  • Use the following commands to upgrade.

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

Failsafe mode

Buttons

hardware.button on howto use and configure the hardware button(s).

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:

BUTTON Event
Reset reset
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

Debricking

generic.debrick

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.

Notes

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.
