I am installing the DGX to my Corona V4. I installed the Post out and the R/W nand kit but when I go to read the nand it doesnt show the device. My soldering is fine any suggestions?

The console shouldn't power on if you have the switch on the adapter set to R/W.

It's hard to tell if your soldering is good or not because those images are blurry.

I had one do this to me tonight. It was the ground on the rw board. I checked with a scope and the ground had perfect connection but device wasn't detected on pc. I soldered a wire from the ground on the board to another ground and it detected it instantly

Those Corona v4s can be a real pain in the a$$.
Try rebooting your laptop,plug in the sd card with ribbon cable attached/set to r/w.
Then open your JR in admin mode.

It should detect the sd card.
In some occasions you may want to try a sd to usb converter and see if that shows any difference.

Always check your soldering and try to get a better picture.
Something a little more clearer.

That soldering is ruff from the pictures i seen..you might have lifted a pad or something under the rw board. Those are extremely sensitive .

That soldering is pretty poor. I would touch up and use flux. Then verify continuity with a multimeter.

Now when I go to turn the xbox on it just makes a sound but the fan doesnt spin and it doesnt turn on. I am keeping this as a stock console so I dont need to read the nand anymore. Why wont it turn on
