mas dudas..
bueno.. no encuentro ningun paralelo que de 3,3 v... asi que con un electronico hemos conseguido que saque a 3,3v el paralelo, poniendo unos ajustables de 100k (son como unos potenciometros o asi)
el tema es que pongo el cacharro le doy al ppflash fw.bin y se queda en flashing, como sino hubiera nada...
no se que mas hacer... los contactos estan bien, lo unico que me mosquea es que en cuanto pones el chip de la DS, me bajan varios cables a 2 v y asi... pero sin ella dan 3,3 v..
asi que ni idea si es normal...
luego mi colega ha puesto un aparato que mide las oscilaciones (tiene un visor como el de los emdicos que controlan la gente en coma y asi) y no se mueve, asi que segun el el ppflash no saca nada por el paralelo... pero me da por hacer un dir > lpt1 y sigue igual...
estara mal el paralelo? porque da los 3,3v.. pero no me fio... y esta en EPP..
he mirado este manual pero nada..
alguna idea?
grazie por leerte el toston..

The things I used for to flash the firmare:
1. A voltage/ohm meter
2. An external power supply (Set it to 3 volts!!!!! Anything more and you'll fry you DS for good!)
3. A soldering iron with a small tip
4. Some soldering wire
5. A printer cable that you don't need anymore. (I cut mine in half) (MAKE SURE YOU USE A CABLE WHERE THE CONNECTOR CAN BE OPENED, OR YOU'LL NEED A SEPARATE CONNECTOR TOO!!)
6. A very sharp and tiny knife.
7. Patience, a whole lot of it.
Recommended: A magnifying glass (you DON'T want to short things out!)
You'll also need a GBA Flash cartridge (NOT SUPERCARD!), like Flash Advance. If you don't have one, you'll need a complete firmware dump (Not just fw.bin as provided by Darkfader).
Ask around for a firmware dump, there are lots of people around that'll want to help you.
Okay.. Step by step:
-Cut the printercable, make it as long as you need, only keep in mind that the longer the cable is, the bigger the chance of garbled packages and you don't want that!
-Solder the wires on the connector end and write down the colors you used on pins: 2,3,4,5,6,13,18. You can cut all other wires away.
-Make sure you have the corresponding colors on the end where you cut the cable in half and make sure they don't touch.
-Now it's time to start ppflash. First thing you need to do is make sure you're LPT port has been set in the BIOS to use EPP. If set, plug in the connector.
Secondly, you'll need at least three DLL's, namely cygwin1.dll, cygioperm-0.dll, cygpopt-0.dll. Furthermore, you'll also need ioperm.exe and ioperm.sys
which you can download from
http://www.cygwin.org.
Open up a command prompt and go to the directory where you put ppflash. Start ioperm -i and then start 'ppflash fw.bin'.
The screen should show you: "Flashing.." or something in that order. Now take your voltage meter and put the Ground end
on the wire that corresponds with pin 18 and put the '+' end on pin 2,3,4,5,6 (either one). The meter should now register something like 3,3 volts.
If it registers 5V, you'll need to use resistors. I can't tell you what kind, because I didn't need them
-Okay, now for the hard part. Stop ppflash and remove the connector from your computer. Now open up your DS.
The picture supplied by Darkfader is clear enough where to put the wires on the mainboard of the DS.
I suggest you start at the bottom of the RFU at the left side (I'm right-handed, so it's easier to work from left to right)
Also, to make an attachment ready for the external powersupply, make an Y-connection on the wire corresponding pin 18 on the connector.
Use one end on pin 2 of the RFU and one end on the Ground of your powersupply.
If you have a steady hand, it should not be too hard. If you feel unsure of your ability to solder, practise on some old piece of hardware.
Lastly solder the +3.3V wire to pin 28 on the RFU, but NOT before you used your sharp knife to cut away the trace between the small dot and the RFU.
Once the trace is cut, you can solder the +3.3V wire to the RFU and make sure you haven't made a connection between the dot and pin 28 again.
-Tape the wires down on the mainboard of the DS (You don't want any wires coming of and start poking around with 3.3V on the mainboard.
It doesn't seem much, but it will RUIN your DS beyond the point of repair.). Now you're set for uploading your firmware.
Put the LPT connector in your computer, attach the power supply to the +3.3V wire and attach the Ground to the split wire of pin 2 on the RFU.
Open up a command prompt on your computer and go to the directpory where you put ppflash. Type in 'ppflash fw.bin' and it should start as soon as you hit 'Enter'.
You should see appearing som code (three lines to be exact) and then you're almost done! REMEMBER: If you don't have a flash cartridge like Flash Advance,
use a complete firmware dump!! It'll take considerably longer to upload, but you're set from the start!
All that is left, is removing the wires you soldered and rebuilding the trace you cut on pin 28. (Just use an excess of soldering tin. No too much mind!)
Put the back lid back on the DS, and insert the battery. You don't have to screw all the screws back in, maybe you'll have to solder again!
If you boot up your DS now, a green light should be visible, if it's not something is definately wrong.
Plug in your socket adapter of the DS and simultaniously turn on your DS.
If your DS boot and immediately shuts off, you most probably have blown out fuse F2 on the mainboard.
THAT is why I recommended not closing your back lid.
Remove the back lid again and look for F2 near the battery connector. Use your meter and see if there is a connection. If there is a connection, there is another
fuse on the other side of the mainboard. If there is no connection, take a tiny piece of wire and bridge the two ends of the fuse. Quick and dirty, but it works.
If your DS boots up, it'll do nothing yet. Put in your Flash cartridge and boot up your DS whilst holding START+SELECT+L+R. The DS will now boot from the cartridge and
you can re-flash the firmware. You may or may not need to short SL1 again, you'll know if the percentage counter stops
If you flashed the complete firmware, You'll immediately get the data-entry screen just as the DS came out of the box.

edito... ya he conseguido meter el firm... pero sigue igual... que puede ser? he leido que con SC no tira.. pero es raro no? alguien sabe algo? hago mal algo al intentar entrar con select+start+a+b?
grazie
