(adsbygoogle = window.adsbygoogle || []).push({}); I have all the points soldered and the right kernel xbox, and I can't dump the nand. I have read that I have to put my XP computers LPT port into SPP but my compute does not have that as an option. What do I do?

Cut my 3 foot ethernet cable and re-solder the end back on to make it shorter, you mean?

Wait, are you running wires directly from the lpt port to the motherboard or are they going through an Ethernet cable? If so how long are the wires on the inside and the outside, if you are using a 3ft cable connected to the lpt connect then shorten that cable by A LOT, 1ft or under.

yeah, im using the ethernet port thing.

i shortened the wires outside to around 1ft and my old errors went away!

any idea what this is?

Hmm, try it again see if you get the same result.

Also check pin 11, is the diode facing the right way?

I just used control-C to kill it and I ran it again, same issue.
I believe the diode is facing the correct way since I bought the Parallel->Ethernet preassembled for the nand-dump specifically for the xbox 360 on ebay.

As far as nandpro, it just keeps going and it looks like every block gives that error. The first run went until 156 (when I killed it) and the current run is at 3A

You may need to lower the resisters then, from 100ohm to say 33ohm, or 66ohm. I would try that BEFORE going with no resisters.

Eh, bit of a problem. The resistors are also inside that ethernet/parallel port, as it was completely prewired.
Before we plugged anything in, we did use a tester to verify that the correct pins had the resistors/diode

It is what I have read some people had to do to make it work. Maybe change parallel port settings as well, put it on bidrectional, or any of the others, try each one.

Well, the options I have are PS/2, EPP, ECP, AT

Which one is bidirectional?

edit, so far i tested:
ps/2, epp, at - all no worky

edit2: right now im testing ecp, if this doesnt work i think im gonna open the adapter up and checkout the stuff, maybe replace the resistors if they're easy assessable

edit3: okay so all of the modes give me that error :( - time to open it up?


edit4 - okay so i opened it up, and the resistors&diode are really tucked away, no way i can do anything to em
