Xbox 360:RGH/RGH2

RGH2 was designed for Slims, but also works for non-Xenon Phats. It uses I2C slowdown instead of PLL slowdown, and works on any dashboard. However, it is considered more difficult to tune and less consistent than the more improved S-RGH. It is only recommended to use RGH 2 with Zephyr models.

• RGH2+ is on Team Xecuter’s later chip firmwares (such as CR4XL) which uses I2C slowdown from the southbridge to glitch. It is considered not very good.

Equipment Needed

• A compatible glitch chip:
  • Coolrunner Rev A/B/C/D or CR3 Lite
  • Matrix Glitcher
  • DGX v1.0S
• A PC running Windows Vista or later
• A soldering iron, solder, and flux (MG 835 recommended)
• Isopropyl alcohol (91% or higher recommended) and cotton swabs
• xFlasher 360, NAND-X, JR-Programmer, or Matrix Flasher
• Postfix Adapter v2 (for a Corona that needs a postfix adapter)
• J-Runner with Extras

(Corona Only) Postfix Adapter

On later Corona motherboards, the POST pad and trace has been hidden, so you need to use a postfix adapter to be able to attach a pogo pin to the POST connection underneath the CPU. Use this diagram to determine if you need one or not. As shown in the diagram, you can install it by carefully sliding the larger piece of the adapter onto the left side of the CPU (when looking at the CPU from a readable position). Gently press the PCB inward toward the CPU to depress the pogo pin, and slide the smaller PCB part over the other side of the CPU, interlocking the two PCBs together. Solder the four anchor points on the edges of the postfix adapter to prevent it from coming loose.

Glitch Chip Installation

Slim

Its recommended to use S-RGH. Please refer to the main page.

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 on the CoolRunner 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 RGH2. # Click "Program". When complete, unplug the cable from the glitch chip.
   • Coolrunner: Set the switch back to "NOR".

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 eMMC (for 4GB Corona) or SPI (for all other motherboards).
2. In the upper right of J-Runner, ensure the Glitch2 radio button is selected.
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.
