From DD-WRT Wiki
Intro
So, you're afraid you've bricked your router. Don't worry, there are a number of things you can try to get your router working again before giving up and living with the fact that your router is now a paperweight.
So far this is just a starter wiki. There's a collection of pointers and tips on how to recover from a bad flash at the external link location. If someone could move the important parts into this wiki, that'd be great. Probably organize it by recovery methods and list variations of each method below the method, or something.
