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; most of them are not obtainable anymore and won't be mentioned.

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
 * A NAND programmer:
 * xFlasher 360
 * Picoflasher
 * NAND-X
 * JR-Programmer
 * Matrix Flasher
 * J-Runner with Extras

Motherboard Points

 * 3.3v
 * Topside near AV
 * PLL
 * Bottom
 * Top (under CPU heatsink, requires scraping)
 * STBY_CLK
 * Bottom (recommended)
 * Topside (There are 2 points boxed, either can be used.)
 * POST
 * Bottom
 * Top (requires scraping)
 * CPU_RST
 * R8C2 (Performs better, recommended)
 * Near PLL
 * J8C1: (Easier to solder)
 * GND
 * Near 3.3v (clean installation)
 * AV Port (A bit easier to solder)

Coolrunner Rev A/B/C/D

 * A - PLL
 * B - STBY_CLK (only if not using oscillator)
 * C - POST
 * D - RST

CR3 Lite

 * A - PLL
 * B - STBY_CLK (only if not using oscillator)
 * C - POST
 * D - RST

Matrix Glitcher

 * A - RST
 * B - POST
 * C - STBY_CLK (only if not using oscillator)
 * F - PLL

Squirt

 * Squirt BGA 1.2: Disable the onboard 670pf and/or 480pf caps by removing R7 and R8
 * Squirt Reloaded 2.X: remove R2 and connect STBY_CLK
 * Pinout follows written labels
 * Don't use POST or RST tuners

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.
