Guys Im having big bropblems with trying to mod chip my xbox! Ive done everything I could possibly do according to the tutorials and I have ordered the right software. Everytime I try to burn a game it doesnt work for me, Im getting DVD error messages saying invalid code (2139patch). What the hell is it??? Ive double checked Ive used the right DVDs. Its not the burner software for sure as I tried isoburner that didnt work so I ended up searching online for a paid service and Im still getting this message so is it maybe something I did to the console it self? Have I not correctly installed it or what I dont know...? Thanks for reading, please try and help me get this fixed. Shane.
