I have a Zephyr that I can't seem to glitch using a Coolrunner Rev C and RGH1. I have left it sitting for over 20min but no luck booting Xell. The strange thing is the Coolrunner will flash a solid bright green like normal for about 1min then after that it still flashes green but it only stays green for 1/2 second and it's not as bright. I have tried with and without the capacitor between A and Ground. I have not tried with a shielded cable for CPU_RST yet. Coolrunner has JP1 closed, JP2 2-3 closed, 100nf CAP open.

Here's my j-runner log

I tried moving cpu_rst away from coils but still no luck. I have now replaced that cable with the shielded one included with the coolunner rev c but it's still not booting xell. What else can I try?

I double checked post_out to make sure it wasn't touching FT6U6 with my multimeter and it's ok. Is this the correct bottom point for cpu_rst? I put it there and it's still not booting xell.

CPU_RST is the same top and bottom. It's a through-hole.

Didn't think I'd need to keep stating this. Thought the 'hey - that arrangement of holes is the same top and bottom. Wonder if they're linked? I'll get my meter out to check' conversation to yourself would have happened long before posting the question.

Zephyrs appear to be hit and miss, ..or in my case miss and miss. I've tried 2 zephyrs now and neither will boot xell for key recovery, tried all the guides and even 50ohm low loss cable etc and repeatedly booting as some say let it try for 30 seconds then reboot, and 1 in 10 times it "may" glitch (no luck for me though)) others say leave it for 15 minutes etc (again no luck).

So Zephyrs are not like falcons and no two are the same, you may get lucky, you may spend 20+ hours trying to make it glitch and it wont. Given the value of the boards these days and the sheer hours of effort involved, i'm now of the opinion that if it doesnt glitch in the first few minutes then give up on it ...they aint worth it.

From what I've read online I think I'll agree with you. I've tried everything I could think of and it's still not booting xell. How do I flash back to stock?

Have to agree with this 100%. Had one Zep that glitched great and another one that is still super stubborn even after 20+ hours of fiddling. The other issue is that they all run hot as hell, somewhere in the vicinity of 80C just idling. Even if you manage to get them to glitch reliably, you will likely need to run the fan louder than a hair dryer to keep the temps down

In Jrunner make sure the correct nanddump you took when you dumped the nands is in the Source File target path and then flash it using nandx (Write Nand button in jrunner)

Pull the power cord on xbox mobo when finished and wait 30 seconds as per normal. If all is well xbox will boot (CR removed or set to PRG).

I reverted to stock and it works fine. The xbox is on dash 13699, would there have been any point updating to a newer dash and trying the glitch?
