Quoted from the NandPro readme:

QUOTE

Some parallel ports run at 3.3v others at 5v. The MAINBRD is 3.3 volts.
Testing with 5 volt lpt and NO resistors didn't burn anything up. YMMV (IMG:style_emoticons/default/tongue.gif)
It is recomnened to use 100 ohm series resistors
for all lpt connections except for DB25.11 and DB25.18 (GND).
This solution isn't perfect but you typically dont leave it hooked up forever anyway.
If someone wants to design and post a buffer circuit go right ahead. I can't be bothered (IMG:style_emoticons/default/wink.gif)

So as far as I can tell, it should be safe, according to Tiros.

But yes you may be right about the 5v LPT port on *some* PCs being unsafe, but this is the only way I was able to make it work with a *fairly* long cable (1.5 meters), otherwise it refused to detect the NAND controller with the resistors in place.

Can the flash chip be simply de-soldered and read/flashed rather than soldering to an lpt connector?

I want to try this on a 2006 box pre hdmi should this work?

Will this work by flashing with Infectus?

Noone seems to have answered my question...

Yes it should work just fine, as long as you have the JTAG resistors in place. (they are necessary to boot Xell, i'm assuming you are referring to this)

Ah ok... So the 330ohm resistors are mandatory for this loader to work?

yes - if you don't connect the 330Ohm resistors, you'll just get E79..

Ok, done my first machine.

I've tried the loader with a Zephyr (HDMI) console - DOES NOT POWER AT ALL after hacked.bin

ALTHOUGH... I may have found an alternative for the newer boards. I'll post up some pics in a sec...

The hacked bin is for xenon only, Each model will have its own so just wait intill the release one for yours.

Good luck on finding the last point because two are easy to find but the last one isn't labeled the same from what I've gathered. And that bin is called Xenon for a reason man, it's for xenon only, they dont wont to release them all at once so people would be cross flashing bins thats why it's going a few at a time. You better hope you can reflash that with the stock NAND, also it might not recognize it because the xenon bin is different then the one for a zephyr. Tiros said there was a trick to jumping a pin on the chip to make it think it was blank, but it's hard to do he said, but it's not impossible.

Would the extract work on a 3ROD box?. I have a Xenon that's dead and will get it heat gunned but just as a test was wondering if this will stop the extract of the EPROM. Logic tells me it wont as powering of the eprom should always happen, irrespective of the state of the xbox. It's a nice way to test the LPT setup works without risking too much if it all fails.

Im interested in knowing this too. I have my launch xenon here with 3rl (been fixed multiple times) and would like to use it for the hack if possible (as a test prior to using a newer console).

Should work fine aslong as the rrod isnt because of something power related and causing the power brick to go red.

Excellent, now i just need a pc with a parallel port

YMMV (IMG:style_emoticons/default/tongue.gif) says enough i think.

The best way for this to work is when you have guidelines that work for everybody, noob proof.
It would be nice to have a guide that incorperates everything we learned here but everyone uses a different method so it is hard to filter the info.

Do you have an option to try 50/20/10 ohms resistors?, would be very interesting.

What kind of cable did you use? (gues: printer cable with the end cut off?)

Tiros: can you give us some insight for using the diode?, voltage drop or 4 ns delay?

Actually it is a shielded 8-wire PlayStation2 extension cable w/ends chopped off. (I chose this cable type for the shielding, IMO a cable that is meant to program a NAND chip should always be shielded)

Let it be known that my LPT port does work correctly with the 100 Ohm resistors in place, but only with cables that are less than 2ft in length, anything longer and I have to remove the resistors to detect the NAND controller.

I would imagine that you are correct about the lower ohm resistors, but I haven't tested this myself.
