Erase the nand and re-flash. NandPro.exe lpt: -e16 0x000000

Again me... Tongue

From the information inside this thread the "only" differences between the xenon motherboard and falcon motherboard are the J1F1 connector (that's missing in the falcon).

Without the 3 resistors on the J1F1 connector (I have a Falcon motherboard) I'm able just to read the nand or isn't enabled both operations (read and write)?

If yes, I can start to build the interface and perform a first dump of the nand and wait for the alternative point of the J1F1 connector...

Please let me know Smiley Thanks.

the 3 330ohm resistors are NOT needed for the programmer

Also a big issue, make sure the parallel cable is NOT too long, i had a 6 ft cable and only got flash as 0x12000 continually with error 0 during flashing.  I halved the cable length and resoldered the parallel connector and all good now grabbing nand as we speak!!!

whilst technically true, they are rather usefull as 99% sure they are current limit resistors which will prevent you from frying smc port / gpu port / both if you do something silly like short to gnd / 5v / something else. kinda like bridging a fuse, sure it makes a device work but can be asking for trouble, especially if its a beta stage hack and you are often opening it up and fiddling changing things as it wont take much to knock / catch a wire

@Shaun

you are writing , but not reading Smiley. 3 x 330 ohm resistors is not needed for reading/writing nand flash , those resistors is used for jtag exploit .

and neither are you. he is talking about the 100 ohm resistors on the lpt flasher, not the jtag port.

Just wanted to throw this out there. If you get errorr 0 on every block, add the diode. I used Diode 1N914 and it worked after that.

Also check the length of you cable between the box andyour pc, I had a 6ft cable previously and got error 0 regularly, I shorted the cable to 3ft and works perfectly.

The LPT port from my PCI multi-IO card on this computer doesn't like the Xbox, while my ~7 years old  Pentium 3 PC accepted it fine.
Bottom line:
Try using a old PC

More often than not, those PCI cards are actually printer ports ONLY.. they don't have all lines hooked up. That's why they i.e. don't work for LCD display controllers either.

Basically, you just flash it. Easy as that.

Managed to get two dumps with no errors, compared them and loads of differences. Didn't really care though as I don't intend return to normal. Flashed with xenon-hacked and inserted new xell-1f. Got composite output working! Will try and flash my original and see if I have any joy

You  cannot use this hack with a 1921 CB, yet.
All things lower than 1921 won't boot on your box since the fuse count for this CB doesn't match.

You'll have to wait for a proper image, like me. I have 2 1921 boxes, too.

Well... I have all the materials for the NAND read / flash. Just fo double confirmation, I can solder on my falcon motherboard all the components (except for the J1F1 resistors) and try to read the NAND without broken my 360?!?!

Thanks :p
