i give up i can't  get the multimeter gague to move on those 5 ive cleaned them and used the desoldering braid

Please take this critique as constructive.
Your workmanship or your tools are letting you down. Those first pics you showed are a real worry. You've got exposed wire and wire with very pronounced kinks in it that will cause all sorts of issues.

The solderpoints have to be completely rid of the old solder and it requires a bit of skill and the right gear to do it properly. Desoldering requires more heat and more time on the point than soldering a wire and with what you have demonstrated so far I'd be very concerned that you are likely to do irreversible damage in the process. You can follow these pointers but I would encourage you to hand this over to more capable hands.

For clearing the solderpoints, use flux with your desoldering braid and use a hotter iron than your 15watt one (25-30watts). Do not hold the iron on the point for long periods. Just get some solder to flow onto the braid and then remove it, cut the braid, reflux and do a bit more. You need to remove all of the existing solder because it is an incompatible solder to the one you are applying. You should be able to see through all of the holes. Clean up the flux with some isopropl alcohol.

Keep all of tips of your wires short. Tinning the tip of the wire will melt back some of the plastic so start short. Your total length of wire from motherboard to DB25 looks to exceed 30cm which is just asking for failure.

330 ohm resistors? Which guide are you following? And who told you to add that diode to the DB25 plug? Put your tools down and start following a proper guide. You've found your way in here but seem to have completely missed page 1. Good luck.

Im not the best at soldering but i checked all connections with a multimeter and all are fine. i was using it wrong before.





Oh and i put he diode back on the board.

he told you that about the 22M Ohms because that´s is fact 22 Mega ohm or 22000000 Ohm resistor! You don´t need that!
you just need the 100 Ohms Resistor 1/4w or 1/2w

Ok before I start I have just one more question. What's the difference between metal (blue) resistors and carbon (brown/tan) resistors? The ones I have are both 100ohms. Just curious.

I read about using Gentoo to dump/flash the nand. Is this cable build just an alternative for future use that's simpler and quicker than Gentoo? Or do they have different purposes?

Gentoo can only be run after the console has been setup for homebrew (nand already flashed). You can use software methods like Gentoo to re-flash it once you are up and running but you'll always need hardware mods like the LPT connection to get you started (at least with the current exploit).

There is also a chance that a software flash can go wrong which leaves you with a console that won't boot. LPT flashing doesn't require the console to be operational so that is why many here choose to permanently attach it.

The metal film resistors are usually smaller and are closer to their rated resistance.

i.e. the carbon 100ohm might be anywhere from 95 to 105 ohms whereas the metal film ones are probably pretty close to exactly 100ohms.

(Short simplified answer, full answer is longer, look up "resistor tolerance" on google for more.)

I tried out garlon's idea and made an easy solder attachment for my LPT cable. It's great!, I used it on 2 consoles last night and it was a lot easier and quicker than soldering wire directly to the mobo. I'd recommend anyone who isn't very confident with soldering to make one. It's also handy if you'll be flashing multiple consoles.

I just used the legs from some resistors to make the probes. I soldered on the wire then wrapped it in some electrical tape to make it easier to hold. Finish it off by covering in some heat shrink to hold everything in place and keep it looking neat  (IMG:style_emoticons/default/biggrin.gif) . Thanks for the idea garlon!.

Anyone know if this wire could work for the future Nandumper ??

Last question.

1)There's any risk (Mayor) if i solder wrong
2)i dont know how can i make this a right question, but i will ask about the cat5 Cable
 - there is some order about the wires (inside the cat5)

i.e: brown/orange/etc must stay/solder in some spot in the mother board or LPT (obligatory)  


Srry for my english/sintaxis =(

Pretty nice job there!
Your welcome thank you too for your great tutorial

Hehe thats y i did a pin header system to dissconnect the flasher w/o removing the LPT calbe from pc. will do a cat-5 system when i get my nand-flasher

hi you cant use that cable because thats a lpt (female) to USB converter.
That should be useful to use some old printers, scanners with newer oca without paralel port.

About soldering the major risk should be shorts with ground ect (u can fry tour board)
About the wires u can use any colour to connect any point on your mobo

Hey all.  I have about 4 wires soldered to the board and have decided that this is out of my league.  I have little to no soldering experience  Is there anyone who would like to take a look at it and finish the job?  I am willing to pay for these services.  If you are in the Orange County, CA area I can drop it off to you.  Thanks in advance.

I can do it. I live in Los Angeles. I purchsed a usb spi nand dumper flasher that is way more reliable than this LPT garbage. I'd still need to solder to the motherboard, but no resistors are required. Let me know if you want to bring it by.

No offense to anyone doing the LPT method. I tried it for days and really wanted it to work but couldn't get a good flash config for the life of me (and I know how to solder with the best of them). So I just picked up grim187's usb spi device.

[GTRagnarok]

Does the orientation of the 5 resistors matter like with the diode?

[Siph3r]

following on from Garlons easy solder solution, what are the pins on the bottom? (the ones that solder into the motherboard) - is that just a close up of bear wire, or is it some kind of pin / prong / needle?

[El3h]

My motherboard doesn't have a Parallel port(LPT) from what I've been reading u cannot use an expansion card for this because it won't work, so my question is:-

I've seen many shops selling usb to parallel adapters, will this work? I'm not worried about the speed, just if nandpro will be able to see the device.
Any advice will be appreciated.
