I am at the same point, scratching my head...
I have Slim Trinity with 15574.
'DGX v1.0S' installed to 'Trinity QSB v3'
Installed 'Slim Post QSB' on the back.
Trying different wire lengths...
What i am not sure is the cable for 'Monitor COM'...
I am using J-Runner v0.2 Beta (287)
Also i have the Demon installed but not using it since i couldn't get my keys yet. (Although tested and confirmed that it's operational)
My settings are:
Demon is on XB and switched to XBOX Nand.
DGX all switches are on the side; closer to the big chip.
'Nand-X USB Update Cable' appears as COM3 and selected as same on the monitor.
Demon, J-Runner and cable software/firmware/drivers are latest.
I am hoping that the 'Nand-X USB Update Cable' mentioned on the J-Runner pdf manual is the same thing as the 'J-RUNNER USB COMMS CABLE' since i have this cable that came with my 'Nand-X RGH Edition' and it is connected to the port on the 'Trinity QSB v3'.
I have written ECC for DGX after dumps.
I even compared my dumps from demon with Nand-X and all are OK. (Nand-X, Trinity QSB v3 and DGX worked connected alltogether)
On DGX, red light on, green blinks once in a while.
Xbox green light blinks until forever.
I hope i don't have to uninstall demon from the back...
I would very much appreciate if someone could confirm i'm on the right track.
Thanks in advance.
