i can attest to the stby clk point causing the "usb device not detected" when trying to read nand or flash it. i have a slim and that was one of my problems. if the nandx prgrams the cr witht he xsvf file then the nandx is working, atleast one would think.
but as others have said the zephyr is tough. those solder points are brutal. i have a benq thats failing in my old zephyr, its 30 bucks for a new drive or a cr. might try the cr just as an experiment.
natedogg, i will try the option 2 when i get around to it. thanks
