reset openWRT firmware with fsg-3

Howto restore FSG-3 with OpenWRT default image


prerequisites:
installed openwrt kernel on flash-partition kern1 and rootfilesystem on /dev/sda1
backuped freecom firmware on flash-partition kern2 and rootfilesystem on /dev/sda2


connect serial console to your fsg-3,


hit ^C when booting to start the RedBoot console prompt and stop processing boot script.


to start the old freecom kernel from the second flash kernel image and the second hdd partition

RedBoot> fis load kern2
RedBoot> exec -c "console=ttyS0,115200 root=/dev/hda2 mem=64M@0x00000000"

make a directory in /tmp

mkdir /tmp/rootfs

mount the first partition with openwrt to this directory

mount /dev/sda1 /tmp/rootfs 

remove the openWRT root file system

rm -rf *

create in the directory the new openWRT root filesystem 

go to the directory

cd /tmp/rootfs
tar zxvf /home/fsg_files/openwrt-ixp4xx-harddisk-rootfs.tar.gz

reboot the rooter 

reboot

Boot OpenWRT 

boot with openwrt kernel kern1 and openwrt rootfilesystem sda1  

RedBoot> fis load kern1
RedBoot> exec -c "console=ttyS0,115200 root=/dev/sda1 init=/etc/preinit "

tada, your filesystem is restored to openWRT defaults

go to /etc/config and edit the network file

to the interface lan 

append  

 option gateway  [your gateway IP]
 option dns  [your dns IP]

and edit line 

        option ipaddr [your IP address]
 

now you can disconnect the serial cable

reboot your fsg3

telnet to your new changed ip address and use passwd to set the root password.

exit from telnet

from now on you can only access via SSH
