FPGA RGH Modchip Adapter Xbox 360 Phat and Slim - $25 (Anaheim)
QR Code Link to This Post
Central IC: Likely an FPGA (e.g., Xilinx Spartan-3 or similar) for generating precise reset glitches to bypass the hypervisor security during boot.
JTAG header (10-pin): Labeled TMS, TCK, TDI, TDO, GND, etc. – used to program the FPGA bitstream with motherboard-specific glitch timings via tools like JR Programmer, NAND-X, or a Xilinx USB cable.
Power/Connection pins:
"UCC" (likely "VCC" for 3.3V/5V power), "SLIM", "GND" for Slim consoles (Trinity/Corona/Winchester MBs).
"FAT" section for Phat consoles (Jasper/Falcon/Zephyr).
A/B/C/D pins: Glitch outputs (e.g., NAND Reset, PLL Bypass, INIT, etc.) soldered to specific MB points.
Other labels: "MS10" (possibly MB revision or model support), passives for voltage regulation.
The two identical boards in the pack are probably spares or for dual-NAND setups (stock + hacked NAND for stealth switching). This was common in the early RGH1/RGH1.2 era, before chip-less methods like RGH3.It's a niche tool from the modding scene (e.g., sold via sites like xconsoles/molext.com alongside your MOLEXT power pack), used with a PC for NAND dumping/programming and glitch tuning. Similar to Matrix Glitcher V1 or custom FPGA boards, but the exact "UCC SLIM/FAT" labeling matches field-modding jigs seen in RGH install photos.
