RGH NAND-X not decteted by Flash tool - Downgrade?

[demonic69]

Hi All
I managed to RGH my Zephyr over the weekend, got it booting Xell and even a dash at one point.
I used Rawflash to try a new build and now the 360 won't glitch, which is fine if I can flash Xell back and keep on trying.
Unfortunately now my NAND-X isn't reading or writing at all. It's detected in windows but no flash tools seem to pick it up, just usb errors..
I've removed it completely and reinstalled and even tried a 2nd PC.
One thread suggested downgrading might work.
Before I try this I was wondering if:-
A) I can downgrade OK? Do I just flash the file like the upgrade?

B) I can still read and write my RGH'd NAND with nandpro 2?

I've not tried flashing the coolrunner yet, but It's working OK at the minute so I'm not too fussed about keeping v3 on the NAND-X if I can still read and write with 2.0

Any help appreciated.

Downgrading is possible but won't help. It's going to more likely be your soldering or a damaged trace.

I'll check the soldering again tonight. Strange how it was fine for a few hours though, then went after one flash...

Cheers

i'm having the same problem,i got nand-x to read my nand & i created a freeboot nand but when i try & flash back to xbox with coolshrimps jtag tool when cmd window comes up it says no usb device found.

i think its something to do with the nandpro v3 update & compatability issues with win 7 64 bit os that i'm using.

has any 1 els had the same trouble & found a cure

I've checked all of my soler points for continuity and they seem fine.
I'll try downgrading and see if the NAND can still be read. I'm assuming I only need V3 for the coolrunner, that I can still read and write the NAND just fine for this hack?
