Hi friends, I am using xbox 360 just by dumping firmware. I have xenon motherboard no hdmi. Dashboard version 16547. But now I looking forward to jtag. But it's not possible (dashboard version is higher then requirements). So is there any alternative methods available? Waiting for reply.
You can look in to the RGH hack, you essentially need to buy a modchip (glitch chip) to perform that hack however.
The X3 key essentially emulates a DVD drive, you will not have access to region free gaming, homebrew, emulators and so on with that. It really depends what you want.
