I : Preamble

A: Compatible Corona

- Your Corona motherboard musn’t have the mmc phison chip linked to the nand => check this picutre

- The Kernel of your mother must be bellow 15574 (it means CB < 13181)

B: Needed materials

You will need :

- Squirt 1.2 or other coolrunner with oscillator

- A CPLD programmer : nand-x, squirt programmer, LPT cable…

- A nand dumper flasher

- Soldering materials

II : Programming the CPLD

A : Squirt[

You will need the 360 squirt programmer and UrJTAG application. Place the files you want to flash your cpld with next to the executable.

Squirt team recommand to use rgh_corona_minusone_nr(suggested).svf , but if you don’t have good result with it, you can try another one.

Then use the following commands :

cable ft2232

detect

svf yourfile.svf

B : Coolrunner

Use your nand-x and nandpro 3.0, place de xsvf file you want to flash next to nandpro 3.0 and use the following command : nandpro xsvf: yourfile.xsvf

II : Making the hacked image

-Use this diagram to solder your nand dumper

- Dump your console’s nand twice usinge Jrunner or nandpro 2.X (nandpro usb: r16 (or 64): nand1.bin): nand1.bin) and make sure they match (fc /b nand1.bin nand2.bin)

- Use Xebuild Gui 2.081 to make the ECC image.

- now flash the ecc image with nandpro and the +w16 command (nandpro usb: +w16 image.ecc)

(i used squirter program, but Jrunner or nandpro 2.X is fine too)

III : Soldering the hardware

IV : let’s glitch

A : Make the console boot

Connect your 360 to your TV, plug the power supply and the network cable, turn it on.

XeLL doesn’t boot with any video

So once you see the debug led stop blinking, it’s the console has booted .

If you don’t have boot at all, check your soldering, play with the CPU_RST length or you can try other jed/xsvf files.

B : Grab the key

Once the console has booted, go back on your computer and launch Xebuild GUI 2.081.

In Tool, use the scan for XeLL features

Put 0-100 in scan range and press Start scanning for Xell

After a few, you should see this =)

Now you can build your Freeboot image, be sure to select RGH 2.0

- Flash it with your favorite software with the -w16 command
