Wit's end trying to JTAG

[MorbidMac]

I've done a search here and elsewhere and done everything I can think of to try and JTAG my 360. I am trying this with a LPT cable (not Nand-X).

It's a Xenon with 2.05. I've successfully flashed the DVD drive, but I cannot get NandPro to even recognize the 360 ("No flash controller detected") I've resoldered with three sets of wires for a total of 6 times. I've verified that the NAND is good, the 360 boots up to the menu normally when not wired up.

I have two computers I have tried to read off of - a Vista machine with a PCI card and an old 2000 machine that has a built in LPT port. I get the same results either way. 95port is installed and 360 is plugged in with RoL attached.

I've heard of testing the connections with a multi-meter, but I can't find a definitive guide to doing this.

Is it possible that I've damaged my board in such a way that my soldered wires will never make a good enough connection to read the nand?

are you making sure that you have the xbox plugged into power (but not turned on)?

how do you know the nand is good if you can't get the computer to recognize the xbox?

YES, you CAN (and many have) damaged their xbox to the point you can't read the nand

 

[MorbidMac]

Oops, sorry... left that part out. Yes, 95port is installed and power supply, with RoL, is attached. System is not on.

IF he did damage the NAND-X NAND solder points that badly he cant read the NAND, could he just do a continuity test (which i also think you use to check if you have a good conection or not) to find the corect points for something like the Infectus NAND reader points ands use them as alt points?

Post photos of your soldering.

"I've heard of testing the connections with a multi-meter, but I can't find a definitive guide to doing this."

You just need to set your multi-meter to continuity mode, put one probe at one end of where you've soldered and the other probe on the other end. If it beeps, you have continuity. It's grade school stuff.

ya but a multi meter can seem more antagonizing than it actualy is especially if some one isn't familiar with one or the symbols or functions

Well he better get familiar with one and get one if he has none because its needed with Jtagging for his peace of mind and so we can rule out its not his wiring.. all he does is set it to sound and touch the point at ether side with the prongs how hard is that...

Okay, multimetered the wires and they all test out. I'll get pictures up soon, but now I'm wondering if it's the PCs and not the soldering job.

Try Nandpro Version B,D and E.

Do you get an error when you put in the command?

How long are your wires?

Did you use the switching diode?

Do you have the 100 OHM resistors in place?

are you using nandpro lpt: -r16 nand1.bin command?

Try changing the BIOS Setting. I use EPP believe it is.

 

[Baz Gee]

Did you try with the "optional" diode on the LPT Cable?

[MorbidMac]

Try Nandpro Version B,D and E. Not yet, but I will try that next.

Do you get an error when you put in the command? No error. NandPro tries the three LPT IO addresses and comes back "no flash controller found"

How long are your wires? A little over a foot long, not to long.

Did you use the switching diode? Yes, have also tried without.

Do you have the 100 OHM resistors in place? Yes, have also tried without.

are you using nandpro lpt: -r16 nand1.bin command? Yes. Followed instructions from many different sources.

Try changing the BIOS Setting. I use EPP believe it is. Have tried SPP, ECP and EPP. No luck.[/QUOTE]

Try getting your wires down to 6 inches.

Make sure your port95 is installed correctly also make sure to restart (This what was giving me a problem. Restarted computer and it started reading the nand)

ou have your switching diode on the MB it self?

 

[MorbidMac]

Yes, the diode is attached to the contact point on the board. Port95 was installed before I even began work on the 360.

 

[TilVl]

Have you tried jtag tool? Try it out. When you run Nandpro do you get a port95 error?

 

[MorbidMac]

I did try JTAG Tool... when I ran NandPro, Windows said the program had caused an error and shut it down. Does that indicate something that I'm not aware of? The other problem is that, on the machine I have JTAG tool on, the LPT card doesn't use the default IO addresses and I have to patch them. Nand runs outside of JTAG tool (still without connecting) but it crashes if run from JTAG Tool.

 

[TilVl]

Might be the problem.

Do you have a PC with onboard LPT?

The crash could be the problem. You changing the I/O address might be causing conflicts. Programs are looking some where else.

Try different PC. If Vista/7 install Port95 make sure you get no errors. You need to run Jtag tool as Admin though.

 

[MorbidMac]

Yeah, the two PCs I have are my main machine which has a PCI LPT port and starts with an IO address of E080. The PC I have that has an onboard LPT is an old 300 MHz machine that I pulled out just to see if I could read the nand and it has Win 2K on it. Either way, NandPro doesn't see the 360.

 

[korn_16_f_t_l]

your trying to read over LPT?

well i use a NAND-X but stuff seems to be REALLY picky when it comes to the order its pluged in i have to plug it in in the following order or else i get errors and weird stuff going on (runing win7 X64)

1) plug in 360 PSU
2) plug in female pin header ends
3)connect wire plug ot NAND-X (if its not done already)
4) connect NAND-X to USB cord

the rest is all pc side dont know how much of this will apply to you if your trying to dump via LPT tho......

could always try installing pinheaders on the mobo and pin plugs on the LPT cable or something and try that order but like i said i have no experience with dumping via LPT and have really only dumped 3 360 NAND's in my whole time messing with stuff

 

[Martin C]

LPT is not recommended whatsoever. Too many factors will weigh against you and the constant soldering/desoldering will finally break something around the points and you'll need it repaired. In fact, it's already possible you've broken a trace or two but without pictures to show either way, it's going to be hard supporting you.

 

[MorbidMac]

Okay, here are the images. This is the best I could do with the camera I have. I apologize if they are a little blurry. I've done my best to minimize the amount of solder at the connection and on the wires.
