RGH CPLD DualNAND Mod v0.1 for CoolRunner
Posted by XanTium | February 13 23:34 EST | News Category: Xbox360
 
Team CodeXecution.Com & Team ModControl.Com released RGH CPLD DualNAND Mod v0.1:


This little CPLD mod allows you to switch two nands directly with an installed Cool Runner like TX Cool Runner or other devices with the same chipset on your reset glitch hacked xbox 360 console.
The modified code isnt locked to a modchip, it isnt that special and you can play with the sourcecode soon to add more functions when you want to do so.

Installation:
Add a 2nd NAND to your Xbox 360 (see pictures/documentations), flash the XSVF file to your TX Cool Runner (or other devices with the same Xilinx CPLD) as usual, switch the NAND with the snyc button while coldboot the xbox 360.

Example:
OrigNAND: power on the xbox and hold the sync button until you see the ring of light
2nd NAND (with freeBOOT): power on your console as always (pressing power to use freeboot, hit eject to use xell/xellous/ xell reloaded)

Note:
Our current mod is only available for xbox 360 trinity (slim) mainboards, a port to other mainboards, sourcecode and a better documentation will be released very soon.
Use it at your own risk on Xbox Live!!!

Forgive me if I'm a little daft on the mod, but do you need any other mods other than the CPLD to do dual-nand? If I'm to understand correctly, all you need is the CPLD/RGH wiring?

Also since everyone else does it.....first?

I believe they also installed a nandwhich on that xbox, the only real difference is the code on the CPLD chip.

it seems no one else can do what the cygnos guys have done.
to cut the CE track on the motherboard is a pain.....

Thats why i got me cygnos rev e but would like
A option where it would just switch off the coolrunner when
It boots of original nand and boot coolrunner with cygnos nand
But without relay thought of leeching the 3.3v of the cygnos but
Heard that is not a good plan.

If anyone has some ideees glad to hear them

i just leave my cpld on all the time now but i did have a 2nd switch on the cygnos usb board going to the 3.3v on/off for cpld so i just flick both switchers togther
also i hooked it to a blue led on the center ring of light to show when its on

but all the extra wire on the 3.3v cpld made it glitch slower so i got fed up with it real quick

thats incorrect, TX demon will be out in a matter of weeks and requires no trace cutting and will show the cygnos360 for what it is, crap.

so is that a second nand soldered directly on top of the orig one ? with just one leg left up for the CE line to the pin ?

i may give this a try on my mates slim lol smile.gif

good idea smile.gif

if we can get hold of the flash chips hehehe

on a second note. do we flash our nandimage.bin file manually to the spare nand ? or jtag it in ?

instructions are a bit iffy

Not that hard, I don't cut my southbridge when doing the nandwich mods. Use 2 10k pullups and done.

the simple diagram looks incorrect.
the NANDs CE are both held high through a 10K all the time i believe. connecting the line turns ON the NAND. If they are not held high when disabled they float and battle and nothing boots... Add a few resistors and done.

Both CE pins should be lifted and tied to the glitch chip, then no traces need to be cut guys.

however cutting a trace is usually easier than lifting a mm wide pin without ruining its pad.

You don't need to lift the original nand ce pin. Just run from bottom of board FT1T1 smile.gif
