Your yellow wire doesn't look good. You should also trim your wires some.

Guys, I've tested with a multimeter from the wires back to the pads on the back, reading good continuity. I've also tested between each wire, reading no continuity. Please, this is not a solder issue, unless my multimeter is lying. Maybe I should return it?

Clean the flux reset the nand-x and try again. Have you used the nand-x before on that pc?

Are you going through the board or just soldering to the top?
I just cleaned with isopropyl alcohol. I reset the nand-x (is there any trick to that or just click it)? Not sure what you mean by through the board. I'm soldering through the top, but read a connection between the back and the wire, so the connection is good.

Yes, I have used the nand-x before on this PC.

When you heat the wire it should go all the way through the board and you should see the wires coming out the bottom. That way it makes the best connection.

Thanks for the input. I'm looking for software suggestions here. As I've mentioned, I have cleaned, resoldred, and tested with a multimeter and my connections are solid.

I have a feeling it's something to do with Windows 7 and the drivers, but can't confirm. I'm going to try a different PC tonight.

Dont think its your soldering.

Your system should still be able find Nand-X. With bad soldering it would not be able to read nand (cant detect flash controller)

Believe its a software issue as you stated.

If you've used that computer before and had no issues then I doubt its software. Send the board to someone who can do it for you before you waste a perfectly good 360.

I'm perfectly capable of doing this myself, do you have any other input to offer besides that? Is it not possible that the nand-x may have a bug or the drivers?

If you' ve used it on that pc and had no problems then its not that.
I've used it with no problems until I had a board go south on me. At that point I uninstalled the drivers and reinstalled. Since then I've been having the problem. I've tried two different mobos and neither will read, same message. I've "fixed" the soldering on each a number of times.

Soldering them to the top is not fixed!! Place the wire directly on top of the pin heat it and it should slide fairly easily all the way through to the bottom of the board. Until then it will not be a solid connection. Or use a desoldering bulb and suck the solder out. After thats done place the wires into the "empty" header and solder it.

Are you telling me that reading continuity between the wire on the top and the solder pad on the back is not as good of a connection as soldering through the board? I'd rather not put that much heat into the board to melt the entire pin header.

You don't even need to heat the board just the wire it should slide through the board with ease. Tin the tip of the iron a little touch the wire for a sec or two and apply a little pressure the wire should go through.

I see a number of threads in the forums of people succesfully flashing/reading multiple times before and all of the sudden it stops. Yet, everyone ignores the fact that there may be an issue with the nand-x. Or at the very least a user issue that kills the nand-x.

I just ordered a new nand-x. If I killed this one it would be nice to know how so I dont do it again. It seems the only feedback you get on these forums anymore is to check your sodlering, things have sure changed since the X3 days.

Also - has anyone ever had issues with the connector/wire assembly from the nand to the nand-x?

Now fully convinced there's something wrong with the nand-x. Resoldered, checked continuiy, even checked continuity from the motherboard to the nand-x connector that plugs into the nand-x, all good.

When I try to read nand I still get "Looking for USB interface device, no device found" error.

Tried on a different computer same thing.

Unplugged the nand-x completely from the computer and hit read nand again, exact same error message.

There is a disconnect between the nand-x and my motherboard. As I mentioned, I've already ordered a nother one, but if anyone has encountered a similar issue and was able to resurrect the nand-x, please let me know.

Please don't post anything about soldering.
