This is going to be a complete noob question, but I hope you can help. I'm at a loss on how to update my Cisco E4200 with TomatoUSB. After all my research, everything tell me Tomato is better than DD-WRT for my router, and safer for that matter. Every instruction I can find tells me to download and just update firmware with the click of a button using the .bin file. But everything I think I find that is correct, downloads as a .trx file.
