    SD Card Connections:

    Important:

    For the x2 GND wires use 12 awg
    For the other connections use 28 awg

    2 = CMD
    3 = GND
    5 = CLK
    6 = GND
    7 = DAT0

    Enable SMC_RESET (VERY IMPORTANT TO DO THIS FIRST!!)
    Place a 200-300 Ohm resister between J4E1.1 and TP4E1

    Disconnect the SMC clock from the Southbridge by removing R4D2.
    Save the resistor as it is needed for the Xbox One to function. If you do lose it then a solder bridge should work as the value is 0 Ohms.

    NAND logic runs on the 1.8v rail and readers try to use 3.3v which is most of them don't work with the Xbox One NAND.

    Bridge a 700-800 Ohm resistor between Pin 1 of U3C3 and Ground. This should make an output 3v3 on the rail without damaging anything becuase the smc is held in reset, so it won't try to power anything on.

    Directly underneath the NAND on the underside of the mobo are access points that will let you easily solder the CMD,DAT0 and CLK lines.

    Everything works better when you hook everything up to the SD reader with everything turned off, then turn the Xbox One on and then plug in the SD reader.

    Oh my days lol, the encryption should be pretty good on this thing but there are some unread devs out there so who knows what if anything will come from it.

    Nice info but gonna still need a decrypted nand dump + cpu key before anything good can happen. But since they made the xbone and ps4 both like a windows gaming pc they pretty much fucked up big time as it is basically windows 8.1 mobo (for xbone anyways) so yeah.. probably easier to exploit since it is basically a 1337 windows 8.1 gaming pc.
