Flashing
This section is in need of cleanup!
Initial flash must be with a tailed build, after which any build with -nv64k can be used.

Per Eko
There is simple way to flash original firmware.
-with router running dd-wrt, telnet in, do "mtd erase linux", wait until finished (2-3 min), then type "reboot"
-now router waits for new firmware - tftp the original .chk file (with your PC set to static IP 192.168.1.10 etc)
-when tftp transfer finishes, wait 3-4 min...

USB Info
The USB port is where you can connect an external USB hard drive or flash drive. Which can do a multitude of things. You can use in as a NAS, storage for a FTP server, use Optware to run external programs like torrent software, samba for sharing files to your network, share a USB printer with your network... The list of possibilities is long, it just takes a little research.
ProFTPd is included in most the newer builds of dd-wrt. Check the features chart to be sure.
A ftp server, file sharing, and a media sever is included in TomatoUSB if your device is compatable.
