Make a backup of /etc and a complete backup of your firmware.
1.) Backup of /etc
cd /tmp && tar czvf etc.tgz /etc
2.) Backup of firmware
cat /dev/mtdblock/1 > /tmp/backup.bin

Just update the image via "mtd".
mtd -e linux -r write freewrt-??.bin linux
This will erase the linux flash partition, write the new image to
flash and reboot the router when finished.
All data kept in /etc is _not_ erased. If you want to erase your
configuration, you need to add -e fwcf. This method is works only
very well, if you are doing minor updates. FWCF just overlays your
changes in RAM and is keeping its data in a separate flash
partition.
If your new image contains new /etc files, they will not show up in
/etc and you need to create/copy them manual.
good luck
Waldemar
