Xbox 360:RGH/RGH1

RGH1 is for non-Xenon phat consoles with dashboard 14699 and lower. It uses CPU_PLL_BYPASS to slow down the CPU. While there were other RGH1-targeted chips, such as EDGE360, X360 Glitchip, Matrix Glitcher 360, and SQUIRT360; this page details how to use RGH1 using a Coolrunner due to their availability.

The original diagrams can be found here: Coolrunner Rev C, CR3 Lite.

Equipment Needed

 * Coolrunner Rev A/B/C/D or CR3 Lite
 * 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
 * J-Runner with Extras

Glitch Chip Installation

 * 1) Affix the Coolrunner on the A/V port with the solder points facing towards the fan cutout.
 * 2) Solder the GND wire to the A/V port.
 * 3) Solder 3v3: Diagram
 * 4) Solder A: Diagram
 * 5) Solder B: Diagram There are 2 points boxed, either can be used.
 * 6) Solder C: Diagram
 * 7) Solder D: There are 2 options for D.
 * 8) * R8C2: Performs better Diagram
 * 9) * J8C1: Easier to solder Diagram

Programming the Glitch Chip

 * 1) Plug the cable from your programmer into the chip programmer. Slide switch on the CoolRunner to "PRG".
 * 2) * If you are using an xFlasher, ensure the switch is set to.
 * 3) 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 RGH1.
 * 4) Click "Program". When complete, unplug the cable from the glitch chip and set the switch back to "NOR".

Decrypting the NAND

 * 1) Connect Ethernet and power on the console. The Coolrunner 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.
 * 2) * If you are using an xFlasher, ensure the switch is set to.
 * 3) In the upper right of J-Runner, ensure the   radio button is selected.
 * 4) Click "Create XeBuild Image". This will take a few moments.
 * 5) Click "Write NAND".
 * 6) Disconnect your programmer when the process completes.
 * 7) 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.
 * 8) Return to the RGH main page and continue in the Cleaning Up section.
