Well my problem has to be the XBox 360 itself. The exact same wiring that I used on my 16 MB consoles does not work on the 512 MB Jasper system. I tried everything possible, resistors with/without diode and no resistors with/without diode. I even tried switching the ground. When I go back to my old 16 MB consoles and do my original wiring, I get no problems and reads fine. Tell me, does that make any sense? My only other option now is to try the USB Method and see if that will produce results. Short of that, I'm lost.

Just run into a same problem, weird thing is that my wiring was working i did get 2 identical dumps yeserday and now after rebooted my pc it says "Could not detect a flash controller!"

I tryed to install again port95nt drivers, after that it did read it but had error in every block, and readed it for a moment of course now it cant dedect it again, weird.

Check if contacts are properly soldered and if contacts aren't shorting any others pieces of xbox...

resoldered everything now it works again, i didnt move/touch anything it just stopped working when i woke up @ morning, guess it had bad soldering.

Good thing some of you used lower value resistors, if you use no resistors and have a 5v PC LPT it will 90% sure blow up your xbox.

Make sure you use Nandpro 2.0B

Try a lower value resistor, also make sure you have the right diode, some people say the diode has to go on the motherboard side(electrically it doesn't matter but maby worth a shot.

Try to disable all programs including Antivirus etc.

Try other bios LPT mode, or other pc (again watch out with the resistors

Total nightmare, soldered everything on (excluding the 330ohm section) with resistors but no diode. It read about half of it and errored, so it was left to finish. Tried again and got:

Testing LPT device address:0378
Testing LPT device address:0278
Testing LPT device address:03BC
Could not detect a flash controller!
Can not continue

Then put the diode on (the wrong way round) and I think it read it a little but immediately errored again. It's been doing the cannot find flash controller thing pretty much since. Tried it with lower value resistors and no resistors and no diode etc etc, more of the same.

But the console is RRoD'ing , 2 lights (the top and bottom left) with the cable unhooked but the wires and connector still on. Is it friar tucked? there's no crossed wire's or solder anywhere to cause shorts, I was under the impression the wires, resistors etc could be left on after???

To add: This pc was able to read and write back to the nand on another 360, altho it was for key retrieval... not that it worked, whatever he was writing back to the nand (xell / xenonhack.bin?) writes back ok but it Rrod's with one red light..

Anyone?

Same applies above but the RRoD is fixed.. forgot to put X clamp screws back on.. yes I know... Still doesn't help the no flash controller issue tho.

I'm having the same problem with my falcon board. I ordered a USB reader from AfterTheInsanity but decided I'd make the LPT reader while I'm waiting but its not working at all and I'm at a loss of what to try next.

I've check my connection by eye and with the continuity setting on a Multi-Meter and everything was fine. I started out with the 5x100 ohm resistors on the DB-25 connector, tried it and it said that it couldn't find the flash controller, I had a lot of bare wires exposed so I wrapped them all in electrical tape but still got the same error.

I removed the 5x100 ohm resistors and tried again, same thing but this time on the first try when I tried to read the NAND the center light blinked green but it still said it couldn't find it. When I tried to read it again the light went off and hasn't come on again since.

My last attempt I tried to remove the diode on 11 but it still won't work and I'm at a complete loss of what to do next. With each modification I tried all four port settings (AT, PS/2, ECP and EPP), when the green light was blinking it was on PS/2. Any other suggestions?

I've exhausted my possibilities for tonight. After removing the diode at 11 I decided to put the 5 100 ohm resistors back on the DB-25 connector since I tested my LPT port and it is 5v. I tried all four LPT modes with all the different IRQs, none of which had any effect.

The only things I have left to try now are resistors below 100 ohms, Ill have to go buy those tomorrow though.

I have officially given up trying to dump the nand via the lpt port, Ive tried everything that I can think of including using the following resistors: 100,68,47,35,15, and 10 ohm. I guess I'll just have to wait for my USB dumper to come.

I have this same problem. I just started working setting up xell last night. Wired everything up, and it wouldn't detect the flash controller. Then I noticed the xbox wouldn't boot up at all on it's own. I pulled all the connections, checked the xbox (which was ok) then put just the nand read/write connections back on. Then the flash detected just fine, and it read with no errors. I dumped the first 2 meg three times and they were all error free and the same. Ran CDInfo to check the CB value, and it's good.

So then I shut it down and put the jtag hack back in (to prepare for gentoo to dump the remainder). Ran a dump again just to be sure. First one had some errors, but the second try came out clean and matched the first 3 from before. But it was getting late, and I didn't have the liveCD on hand, so I shut it down for the day. And left it all exactly as was.

This morning, I fired it back up and tried to write the xell to the nand first thing - the flash config detected wrong (00CCsomething) and it errored on writing every block so I aborted it. Tried a read instead (which I should have done first) and got the could not detect flash. All the points still seem solid, and the xbox boots on it's own if the power button is pressed. But I'd randomly get not detected or flash controller 0044something on a read.

So close! Arg!

Doh. Just realized I quoted the wrong post - heh - meant to quote this one:

"resoldered everything now it works again, i didnt move/touch anything it just stopped working when i woke up @ morning, guess it had bad soldering."

That's the similar problem I had.

Please update if you try the USB method.
I was able to read a Jasper but I cannot read my zephyr (does not detect). Same wires setup etc. Anyone else have this problem? Any ideas?

I had the same problem. Worked fine on my Xenon, then soldered the same cable on to my Falcon but couldn't get the flash detected at all

I eventually worked it out....

I'm admitting to my stupidity here just in case it helps others. I had soldered the wires to the JTAG set of pads i.e. J2D2 instead of J1D2. Checked all the wires, bleeped them out, double checked, resoldered. Totally couldn't see the wood for the trees.

Unsurprisingly soldering them onto the correct pads, it worked straight away. DOH!

Also, this worked both with and without the 100 ohm resistors.

I'm have this same error--"Could not detect flash controller"--with my Falcon board. This is my first attempt at it, and I'm an amateur solderer but I believe I've wired everything up correctly.

I've gone through all the BIOS settings, and I'm about to desolder my wires and try it without the resistors.
I have 100 ohm resistors and the 1N4148 diode directly on the board. Any suggestions on what I should try next? Remove just the diode? Remove all resistors, keep the diode? Remove everything? Just wondering because it takes forever for me to solder.

Edit: I decided to take a picture so if anyone can spot something I've done wrong, please let me know.

Edit2: I also tried powering on my 360 and it powers on when the LPT cable is NOT connected to the PC, but it does not when it is connected. Even when the computer is off, if it is connected, it won't boot. Is that the desired behavior?
