Xbox 360:RGH/RGH1.2

RGH1.2 combines RGH1-like PLL slowdown with Glitch2 images to allow reliable glitching of Falcon/Jasper consoles with split CB (post 14699 kernel). RGH1.2 V2 ports this hack to Trinity/Corona consoles as well as fixing a few issues on Jaspers.

Programming the Glitch Chip

1. Plug the cable from your programmer into the chip programmer.
   • If you are using an xFlasher, ensure the switch is set to SPI.
   • CoolRunner: Slide switch to "PRG".
2. Open J-Runner with Extras. Click "Program Timing File" in the upper left and select your console’s tab and the relevant radio button for RGH 1.2.
3. Click "Program". When complete, unplug the cable from the glitch chip.
   • Coolrunner: Set the switch back to "NOR".

X360ACE V4/V5/V3+

• xFlasher or other Gowin compatible programmer required in order to program these chips
• Programming Instructions

Decrypting the NAND

1. Connect Ethernet and power on the console. The glitch chip should blink once or more times, and then the console should start into XeLL RELOADED.
2. Once XeLL finishes, it will display your CPU key and some other info. There is also an IP address.
3. Enter the IP address into the box on the lower right of J-Runner and click "Get CPU Key". J-Runner will pull the info from the box, and decrypt the NANDs automatically.

Writing New NAND Image

1. Power down the console, and connect your programmer to the motherboard.
   • If you are using an xFlasher, ensure the switch is set to SPI.
2. In the upper right of J-Runner, ensure the Glitch2 radio button is selected.
   • Make sure SMC+ is enabled for better boot times.
3. Click "Create XeBuild Image". This will take a few moments.
4. Click "Write NAND".
5. Disconnect your programmer when the process completes.
6. Boot the console several times and ensure it boots consistently. If not, make sure your wiring is clean and neat and avoids noisy area. Run the wires near the X-Clamps for best results.
7. Return to the RGH main page and continue in the Cleaning Up section.
