RGH PLL Bypass

Hello everyone,
I finally got all my stuff in yesterday and have installed the coolrunner on my Jasper 512. But I am having some issues with PLL Bypass (Green Wire). I borked the pad, and now have the wire on the alt point (right near the pad on that resistor). Looking at the Alt point sticky, it says to also scrape a point on the other side and solder a wire to it.
So... I am a bit confused on the wiring of that. Is it just one wire between the point on the resistor and the point on top? Or is it two separate wires, both leading to A on the coolrunner? Sorry if that's a stupid ? but I need some clarification.
Also, how exactly do you flash the original nand.bin back, as I forgot to update the dash. Is it this syntax?
nandpro usb: +w512 nand.bin
or this?
nandpro usb: -w512 nand.bin

One more dumb question: Is it safe to boot the xbox while the mobo is out or does it need to be reinstalled into the chassis with all screws in?

Thanks in advance, I have done a LOT of reading but cannot find clear answers to these questions.

You would use nandpro usb: -w512 nand.bin to flash back the original nand.

On a BB (Big Block NAND, found in Jasper Arcades 256/512) you would want to make a few dumps of the full 512 nand using (nandpro usb: -r512 nand.bin). For your dash nand dump for creating your jtag dash and ECC you would only need to dump the first 64mb (nandpro usb: -r64 nand.bin).


I always do 4 of each 512/64 making sure all 4 match. The last thing you want is a bad dump after you write.

Once you create your ECC you would write it with nandpro usb: +w not -w


You can run the XBOX Motherboard outside of the case on a flat stable surface.

Additionally, you may need a 68nF capacitor to get the Jasper to glitch/boot. If not, you may want to get one anyway to make it boot faster.

Okay, I was writing with +w and got e79, then nothing at all. Trying -w now. Good god, it takes a long time to flash a 512 nand!

Is that all I need to do besides unplug, wait 2 min, then it should boot up? I've read on here something about the ECC. At this point I'm only trying to get back to the original dash so I can update it to 604.

If all that goes well, I still need to figure out the PLL bypass thing. I have it soldered to the resistor just as shown on the alt point sticky, but need some clarification on that.

I really appreciate the help.

Edit: Fixed! I must be the luckiest SOB alive, got desperate and tried the PLL point again, I can now boot to xell got CPU key and have since flashed new nand with 360_Multi_Builder_v0.3, YAY like a MOFO!

Only fear now is putting it all back together, used hot glue but fear compression....
