Note: Due to a couple of problems, one of them being the closed source blobs needed for Broadcom chipsets to work, this project is still WIP and not yet supported by OpenWrt! For more Information look here: wip

Project is still WIP
First let's have a quick view at the Flash Layout with the stock firmware and after OpenWrt has been installed. When you later want to understand, what the programs
sysupgrade do, have a second look here:
- Obtain the data:
|The instructions below are for Broadcom devices and only serve as an example. Don't leave them in place if they do not apply to a particular device!|
This section deals with how you install OpenWrt from a device freshly opened. Plus the steps required such as reset to factory defaults if the device has already been configured
Note: Reset router to factory defaults if it has been previously configured.
If you want to upgrade using TFTP you follow these steps (as an alternative to the above install process.
If you have already installed OpenWrt and like to reflash for e.g. upgrading to a new OpenWrt version you can upgrade using the mtd command line tool. It is important that you put the firmware image into the ramdisk (/tmp) before you start flashing.
- Browse to http://192.168.1.1/cgi-bin/luci/mini/system/upgrade/ LuCI Upgrade URL
- Upload image file for sysupgrade to LuCI
- Wait for reboot
- Login as root via SSH on 192.168.1.1
- Use the following commands to upgrade.
cd /tmp/ wget http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc sysupgrade /tmp/xxx.abc
- If sysupgrade does not support this router, use the following commands.
cd /tmp/ wget http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc mtd write /tmp/xxx.abc linux && reboot
→ Basic configuration After flashing, proceed with this.
Set up your Internet connection, configure wireless, configure USB port, etc.
