Me: Trying to Dump Nand to do a JTAG
Nandpro: "Could not detect flash controller!"
Me: "ARRRRRRGGGGG!!!!! You stupid f$%^in# JUST WORK ALREADY!!!" (burning solder on my eyeball)
Here are some details on my setup:
System Dash version: 2.0.7369.0
Xbox: Jasper 16MB
Nandpro: have tried versions 2b-2e
Memory access showing up in device manager just fine
PC OS: have tried vista 32bit, XP Home 64bit
Using TIAO USB SPI
Wires soldered and connected to the correct locations on the USB SPI (I checked and rechecked)
Xbox plugged in, power supply has it's light on, but the console is not powered on.
Now everywhere I've read about this issue, the consensus seems to be that it's a soldering issue. So, with that in mind, I got myself a multimeter and did some testing. I should say at the outset that I have no idea how to use this tool. All I know is that if the needle goes up then I have a circuit, and the higher the needle goes, the better the connection. I first tested the soldering that I did on the wires (connecting the header pins to the wire). All check out OK (needle buried). Next, I checked for shorts in my soldering by connecting to each of the 6 wires (not ground J1D2.6) in combination. The needle didn't budge, so no shorts, right? Next, I attached to the ground wire (J1D2.6) in combination with each of the 6 wires. Here are the results:
J1D2.1 - Around 9 on the multimeter (See linked photo)
J1D2.2 - Around 9 on the multimeter (See linked photo)
J1D2.3 - Around 9 on the multimeter (See linked photo)
J1D2.4 - Around 9 on the multimeter (See linked photo)
J2B1.5 - Around 20 on the multimeter (no photo for this one...you get the idea...not as good a connection)
J2B1.6 - Around 9 on the multimeter (See linked photo)
It seems that 5 of the wires have very consistent readings, except J2B1.5 which has a lower reading. I decided to re-solder this wire, and got the same results. I even sampled directly on the lump of solder on the mobo and got the exact same results.
So, here are my questions:
1) Are the results from the multimeter testing at all valid? Do they indicate anything at all? Should I have done the testing in a different way? Should I have taken electronics instead of Home-Ec in highschool?
2) How does my soldering look? Does it look like it needs to be redone by someone who has a clue?
3) Should I try the lpt port method instead of using the USP SPI I bought from Tiao? With all the practice I'm getting on soldering I think I could get that done in a flash
4) Do I need to upgrade the dash board to the recommended version to get this sucker to dump the nand? I realize that it's necessary to update at some point, but is it stopping the nand dump right now?
5) I did notice when the USB SPI is not plugged into the PC (through USB), but the Xbox has the power cable plugged in, the red power light on the USB SPI is lit faintly. Does this indicate an issue?
6) I've read a lot of suggestions to keep the wires as short as possible. These suggestions are mainly for those using the LPT method. Does this apply to those using USB? I've got around 40cms of wire connecting the xbox to the USB device. Is this a possible cause of issue?
Additional details:
I actually started by soldering the connections, then realized that I had bought the solderless add on. I de-soldered the wires, and used the solderless add-on with the pogo pins. I ended up successfully dumping part of the nand, but could not hold the pogo pins on the mobo. They kept slipping around, probably because of the extra solder I left on the pads. So, I decided to go back to soldering the connections, and have had the "Could not detect flash controller!" message ever since.
Anyhow, anyone that can help, it's much appreciated.
