I know you've tried everything and it seems you know more than I do but I ran into the same problem as you with my elite cb 6751 16mb the only thing that worked for me was to create the .ecc with multi builder v0.2 not v0.3 and flash it with jtag tool not nandpro worth a shot since you've pretty much tried everything. Good luck
RGH Jasper 6751 Help
- Thread starter WNYConsoles
- Start date
That's what I have been doing. Create with 0.2 and flash with JTAG Tool. Also tried flashing the ECC with nandpro with same results.
If you don't mind me asking, are you using the capacitor on the CoolRunner and what is your XBOX's manufacture date.
I was also thinking of making my NAND dump public and maybe a few friendly forum members could create a ECC image for me to try.

I didn't used any capacitors. As far as the manuf date I'll get back at you since I'm working right now.
Here are my nand dumps if anyone wants to create a ECC for me to test, I would greatly appreciate it.

Additionally, correct me if I am wrong but if the ECC is correct I will see the xbox reboot every 5 seconds until it is glitched. I hear the fan kick in and out every 5 seconds or so but not when the green led blinks.

Rogero's 360 Multi Builder will automatically use a donor 6750 CB version for a Jasper NAND with a 6751 CB.
I have already done the donor nand deal, I knew that's how it's done on 6751 nands. I have tried probably 20 different ECC images from every possible tool with regular and donor, it still don't work.
When is a TX dev going to weigh in on the issue I am having?? I am not the only one with a 6751 nand who can't get the TX CoolRunner to work on.

How coiled is the wire you soldered to the back. I forgot what its called but its the one you have to hot glue or tape. Try adjusting that or use a vga cable instead of an hdmi (if thats the case for you). I highly doubt that it is a vga vs hdmi issue however.

EDIT: look at this picture and try and copy the positioning of the wire (if you havent done so already) (Link). The wires are CPU_RST , POST_OUT1 , and PLL_ BYPASS.

Although I doubt its the way the wires are routed I have read on the forums that wire position can make a difference so I will give it a try doing it exactly the way it is done in the official tutorial.
Will post back tomorrow. Thanks for the suggestion, hope it works!

Same result. Re-wired exactly like official tutorial image, triple checked soldering and continuity and still just green led blink and no signal.
Can a few forum members create a ECC based off my nand dump (links below) so I can test it. I am pretty much at the end of the rope with the CoolRunner, about to pack it in and return them.

FINALLY!!!!!!!!!!!!!
Got two Jaspers to boot, one 16mb and another BB 512.
I had to install two 68nF caps on Ground and PLL.
Additionally, booting is still slow on the 16MB so I had to add a 3rd 68nF on Ground/PLL AND on RST so thats 4 total 68nF caps on the CoolRunner Board, 3 necessary just to boot!
Will post my install pics on the BB Jasper later. I also "discovered" a better way to solder PLL Bypass on the bottom of the board creating a better solid connection which increases boot times.

nice one - I just did a 16MB Jasper last night - couldn't get it to glitch at all - had to move the CPU_RST wire closer to the xclamps to get it to boot....but it is slow at glitching most of the time - haven't tried any caps yet

When you install caps in parallel, capacitance is added.
68nF * 4 = 272nF
That's stupidly high TBH. Are you getting consistent boots at this level?

I thought it was the other way around..
according to
http://www.coilgun.info/theorycapacitors/capacitors2.htm
Capacitors connected in parallel will add their capacitance together.

Thats correct, capacitors in series half the capacitance, where as resisters is the other way around
