Factory Defaulting Router Station

[bvagnoni]

If you want to factory default your router the easiest way I've found so far is to:

Note: Connect via serial it makes things much easier to see what goes on.

Flash with the latest snapshot from:

http://downloads.openwrt.org/snapshots/ar71xx/openwrt-ar71xx-ubnt-rs-squashfs.bin

Note: takes about 3 - 5 minutes to clear jffs, wait for it to finish. When you see the following it's ok to reboot and re-flash. You will only see these messages most likely via serial unless you wait and refresh dmesg.

jffs2_scan_eraseblock(): End of filesystem marker found at 0x0
jffs2_build_filesystem(): unlocking the mtd device... done.
jffs2_build_filesystem(): erasing all blocks after the end marker... done.
mini_fo: using base directory: /
mini_fo: using storage directory: /jffs


Then re-flash with factory firmware:

http://www.ubnt.com/downloads/RS/RSx.ar7100.OpenWRT.bin

and you will be at factory. You could also run /bin/./firstboot.

I'm sure there are better ways to do this but it works.

Thanks for this. I had tried to update packages and could not gain access to the device. Just a quick question, what's wrong with staying at the snapshot version? I just went to X-WRT and flashed with the latest snapshot and this thing is working better then it did from the factory. I just flipped eth0 and eth1 in regards to lan and wan and I'm online now typing using the Routerstation. I know the file is only 2mb but I'm sure the factory version is bigger from more drivers, software, etc...

In OpenWrt, when you flashed an image that has squashfs, you just need to erase the partition called "rootfs_data". This is the jffs2 partition.

This will make it to return to the state when it was last flashed and after reboot mini_fo runs again like the first time.

The command to use is mtd -r erase rootfs_data
