is there any way to unban a NONJTAG xbox without phsically opening the xbox and moving hardware! Please dont put that's what you get or you were banned for a reason I bought it off of eBay because I didn't need LIVE but now I want it!
Nope if the 360 is Jtaggable you can swap the keyvault, update it and go on live. But the console likely wont be if you have played any game released since the end of 2009 on it, you would have to open it to do that anyway.
