I found the image on the official announcement forum and took a chance that i could flash Vera the same way that you can flash normal Asus WL500gP routers with OpenWRT.
If you double-click the back restore button on the back, Vera should do a hardware reset and revert to all the default settings. I just added a bug report to confirm that the hardware reset also resets the networking in openwrt. We might have overlooked this.
