I have read a number of threads in the last 2 weeks were someone has said I attempted to mod and now my Xbox does not work. Seems to me that these people are forgetting what every tutorial around says thats to backup your files. Do yourself a favor before you make any modifications: Take folders C & E and burn them onto a CD, DON'T back them up onto your Xbox, or put them on your PC, make a folder in your My Documents such as My Xbox place a copy of your original C & E folders there. Now, if anything goes wrong you take the CD, put it in your Xbox use Xplorer or the file manager, delete the entire C & E folders from the failed mod attempt, then transfer in the folders from your CD or FTP the folders from your PC back into place and you are back where you began.
Nice tutorial. Short and to the point. This will help people that are new to this! Good job shademand!
