I have been modding xboxes in the Boise, Idaho area since 2004. I just moved to Dallas, Texas.
I have been soldering for over 20 years, and I guarantee my work.
Do you want to have a modchip installed? Do you want someone to softmod your box? Have a bricked system you need fixed?
I do all that, while you watch.
I can modify your system, and teach you all you need to know about how to use it. I can even install Linux for you. I can add USB ports to your system or controller, or build a cable for you. I can even install wireless receivers inside the xbox for you. The only thing I don't do is case mods.
Thanks for looking!
