    I dumped the nand on my xbox and it's no longer booting. No chime sound, no lights on the console, and the power brick light is solid orange and non changing. Has anyone else experienced this?

    I followed this guide: http://www.sthetix.net/tutorial/xbox-one/tutorial-dump-nand-xbox-one
    and made sure to bridge the resistor that was removed in the process. After realizing that the console would not boot, I rewired the nand dumping rig and made another dump to make sure that the nand had not been corrupted and it was the same as the original dump that I made.

    Any insight would be appreciated!

    I have no experience with the xbox one yet.
    But as I can see with the picture,
    you should check out the small resistors next too the xbox labeled chip.
    Maby try too put the original back on it?

    And did you double check for solder blobs on the solder points?

    Unfortunately the original resistor fell on my floor somewhere and will be near impossible to find now at it's pretty small. All of the points I soldered to look pretty clean.

    This post mentions a similar problem after a write back to the nand. It says that the voltage register for the nand (set by a microcontroller within the nand itself) is set to 3.3v and not switched back to 1.8v like the xbox would normally operate at. Basically the nand can't be read by the console because it's expecting 3.3v but only getting 1.8v. His fix was to basically force the nand to 3.3v and then boot the console. The console would then reset the nand to operate at 1.8v. That fix didn't work for me but I'm wondering if I could somehow manually send the command (cmd11) to switch the voltage register back to 1.8v operation. There doesn't seem to be any tools out there at the moment for manually sending commands to mmc/sd that I can find. If I could at least send the command to read the voltage register. That would be a start in determining if it's set incorrectly.
