CoolRunner No green light, NEED HELP!

[Kinect360]

So I removed the JTAG QCB, now, should it work (im guessing not, and that was a stupid question)?

Ill try to start from the beginning, but can you program the CR even if its hooked up to the xbox360?

 

[Kinect360]

Ok, so now I cant get a good nand dump at all... Flash tool doesnt want to open them... I still have my two original nand dumps which are fine.

Rechecked the solder points, all seem to be good. Will try to dump again.

 

[Kinect360]

Still doesnt work... Should I take off the QCBs and put pin headers instead? Since they dont seem to be working :facepalm::mad2::facepalm:

 

[blastagator]

Did you ever attempt to write the NAND? (Might have done bad flash if it isn't reading correctly now.)

Use a meter and check continuity between the connector pins on the QSB and the motherboard (preferably to an alternate point on the motherboard, that way you can verify good continuity)

Also, make sure nothing is shorted (anywhere you've done any soldering).

 

[Kinect360]

Ok thanks, and I did try to write to my nand, but the CR didnt want to glitch, maybe because of bad flash?

So should I try to write the original nand dump back to nand ?

Thanks!

I don't know if Flash Tool will read a NAND that has been modified with ECC (which is what you would be reading off the board now if you flashed the ECC).

You can use a virtual nand with nandpro.
Make a COPY of the original dump and put it in the nandpro folder.
Instead of using usb/lpt use the filename.
So nandpro file.bin:
This will allow you to append the ecc to this nand file
nandpro file.bin: +w16 000.ecc
(Of course with the right file names)
Then compare this virtual nand with what you have been dumping off of the console. If they match, life is good


FYI, I just tested this by patching my original nand with my ECC. 360 flash no longer reads the nand, it says invalid. So I would say it is likely you are okay, BUT follow the procedure above and compare the new dump with that created virtual nand. The last thing you want to do is lose your original NAND!!!!!

 

[Kinect360]

My two original nands are fine, so the nand on my xbox, it is patched with a different ECC and thats why it cant be read in flash tool... So, why cant I boot XELL?

 

[blastagator]

Did you program the CoolRunner with the appropriate timing file? (They don't come programmed...)

If you did, check solder connections with meter. Lack of green light is generally due to faulty connection to CPU Bypass (or you shorted that point to something around it)

 

[Kinect360]

Yes I did, but at the begginning of the post, I said I installed everything at once, but im guessing it should of still programmed even if it was hooked up to the box, right?

And I'll check that solder point, thanks!
So the CPU bypass is the green wire, A, right?

 

[blastagator]

When you programmed it as long as it didn't kick any errors it probably programmed fine. You can do it hooked up to the xbox, as long as the red light is lit it should program.

Check wiring with multimeter, not just your eyeballs.

The green wire is the likely problem, yes. If your soldering skills are questionable you might want to use an alternate point (refer to the thread).

 

[Kinect360]

Yeah it programmed fine and all, so the green wire, awsome! I have hope now to get this thing working! Will check the green wire, and maybe try and alternate point!

 

[Kinect360]

OK so, this would be the alternate point, correct?

Im confused, as in his pictures, he soldered the original wire here, and I soldered mine here.

Which one is correct?!? That might be the reason this thing isint working... lol:facepalm:

Thanks!

 

[blastagator]

If you used a meter you would see that there is continuity between those two points (thus either spot is fine). You can use the meter to check for continuity between the CR and the resistor (the thing he soldered to).

Also use the meter to check for continuity between both sides of the part just above the circled point and the pad just to the right. (There shouldn't be continuity)

 

[d4rk_4ng3l]

and I soldered mine here.

YOU'RE 10000% CORRECT.
You should only use alternate points if you messed up your ORIGINAL SOLDER PAD.But in you pic the ORIGINAL SOLDER PAD LOOKED PERFECT.

We'll I'm assuming you do have a falcon board right?
if yes then just follow this when you're using QSB
Xecuter CoolRunner - Phat Install (QSB)

Do not get confused, take it easy. It sounds, feels, looks like you're too much excited with this.

And don't forget to click the THANKS button as anyone gave you some help.

 

[Kinect360]

Tested those two points for continuity, and seemed fine, resolder the wire just to make sure, and turned it on, no green light

Could it be another wire?

 

[d4rk_4ng3l]

Kinect360, did you follow the guide link iI just sent you?
I think you're picking things up from here and there.
And which two points???
Just follow one single guide so that it'd be easier to get you some help.
No green light on where CoolRunner or on xbox360?

 

[Kinect360]

No green light on the cool runner of course, and the point where u solder wire A and the resistor...
And yes I did.

 

[d4rk_4ng3l]

Okay, stop exactly where you are and check to see if your wiring looks exactly the way it shows in the following pic

And post your result

 

[Kinect360]

Yes, Im pretty sure it correct. Here are the pics. Correct me if im wrong...

 

[blastagator]

You took out the JTAG crap right?

To check B make sure you have continuity between the two things I circled in Red.

What type of motherboard do you have and what is the CB version?
