Better off hacking yourself.
I did it for under £20 (Already have a soldering iron), I'd recommend the following method via R-JTOP(R-JTAG), you'll need the following:
- Cool runner Rev C
- Matrix SPI Nand flasher
- 3.3v Zener diode
- 3x 100 ohm resistors
- 2x 10K resistor
- 2x BC547B transistor
Here's some tips:
- Get a glue gun to hold the wires down because the tiny solder points VERY easily rip off under tension
- Don't use a overly cheap soldering iron (The tips are garbage and die quick)
- Be VERY cautious with the wires and tiny solder points (I know I've said it but I can't stress enough how important it is)
- If you can buy a fine soldering wire that's not thick (This will make it easier soldering those tiny points)
- Get FLUX it helps keep all those joints well and flowing properly.
- Sometimes and in my case the Matrix nand flasher will report in J-Runner it's failed to write to xyz block, ignore it (It actually has written).
Cost break down of parts:
- 10x 3.3v Zener diode £1
- 5x BC547B transistors £1.20
- Matrix NAND flasher £6.50
- Assortment of resistors £3-£5
- Cool runner Rev C £5
TOTAL: £16.70 - £18.70
Just do the following:
- Install aud_clamp (Just google it and if you use the BC547B transistors ensure flat side IS facing GPU heatsink)
- Modify the Matrix SPI flasher to program the Rev C & Read nand: [LINK]
- Program the Cool runner Rev C with the R-JTOP files (I can provide links to falcon and jasper files via DM and compile for others)
- Extract the 360 NAND (Ensure console is PLUGGED IN but NOT POWERED ON)
- Create Xell reloaded image (Make sure in J-Runner you select JTAG then tick Aud_Clamp and R-JTAG)
- Install CR RevC and start console
- Copy down your CPU key and make the XeBuild image for your console dash
- Write the built file to your NAND and enjoy.
