Nandpro wont detect flash controller and your 360s power and eject button do nothing.

requires external +5 (red) and ground (black).
(usb cable, molex connector, etc.)

Zephyr:

Falcon:

Disconnect Motherboard from PSU, Plug in External Power, Flash, Disconnect External Power and Test.

Warning: if you plug in external power while the psu is connected you could kill the console!

whats wrong with shorting pins 41/42/43/44 to stop IO to the NAND and bypass SMC code on nand?

either way, still good to see you can flash the 360 nand with no PSU.

Shorting pins 41/42/43/44 to stop IO i have today killed my nand not sure how yet as it was writing fine but when i tried the power the console i got nothing (dead) i have tried shorting pins 47 and 44 but still cant re-flash nand.

i might add i my rush to fix i pulled off the pad of pin 47 sad.gif not sure if this will effect anything yet uhh.gif

it was all going so well lol

Is there any thing i need to do i regards to powering up and so on

ive seen
short pins
apply power from brick
remove short on pins
and see if the nand can be seen

I'm not exactly understanding how you connect the powers to the external power source

USB is 5 volts so cut up a USB cable and connect the red wire to positive and the black to ground

how have people been connecting the wires to the xbox points? Do you just solder them on while reviving/reflashing then unsolder them when done?

With USB could I cut a printer cable off at the printer end solder the red wire to the red point and black to the black point and then plug the other end into a computer?

Hoping this helps my falcon which doesn't power up and the flash controller can't be found as shorting the pins on the NAND hasn't helped me so far

How do you even know what mobo you have? I know I dont have a xenon.

Anyways, for the top one, we need to ground both pins right?

Just wondering what the difference between this method and shorting pins 44-47 is, as per this tut:

http://forums.afterd...ead_360-826514/

Which would be safer for the mobo? Has anyone successfully used this technique? Thanks in advance.

Sorry for the bump but I was unable to edit. I tried this technique using USB as external power source, but was unable to get rid of "cannot detect flash controller" error. I attempted this on a falcon mobo. Could this have damaged my nand?
