OK... I installed a NME v2 on a Hitachi 47D drive. The console will now only play DVD's. I've tried original XBOX and XBOX360 games. I've also tried a backup I made for the NME and it did not work. So opened the 360 again and I disconnected the ground and 5V wires. I then booted the console and got Error 64. It won't even go to the dashboard screen, it just stops at the XBOX360 logo. After that happened, I suspected that some of the wires soldered to the flash were touching each other. I checked each connection with a voltmeter and everything checks out fine. The only thing I can think of is that there may be something wrong with the GND or 5V wires. A couple of side notes:

1) When I booted the console with the chip powered on, I got Error 76 on the first boot and then it went away and didn't come back up until the power was unplugged and plugged back in.

2) I have all optional points soldered to the chip.( makes it a 15 wire install)

3) J1 is soldered together.

Any suggestions are greatly appreciated.

anyone have any feedback for this? I'm having the exact same problem.

I'm not sure I can offer much other than the obvious.

I suggest you check (trace out) all wiring from point to point. i.e. trace each wire from connection on the NME2 to the point of soldering on the drive. Make sure all wires are soldered to the correct point on the drive. Especially points A to I where they connect to the pads that are next to one another. Make sure there is no solder bridging across these connections. You may wish to use your voltmeter to check for bridges across the pads. Set the meter to ohms, or diode check if this has a sounder, and check all adjacent pad to see if there is a short.

If all checks out and still no good. The next step would be to disconnect the NME2 completely to check that the XBox has not been damaged in the install.

Good luck. The Hitachi install is a difficult one due to the number of connections.

[crapoid685]

Thanks for the reply. I went ahead and removed the chip completely and cleaned up the install and now the 360 functions properly. I could have sworn there were no bridges, but I guess there were. The only thing that really threw me off was the fact that it played DVD movies. I am using 30 gauge wire but that still seems to be a little too thick for the 9 points soldered to the flash. I am going to try to reinstall the chip using an IDE cable, as I have heard that the wires in those cables are 32 gauge. I will post back when I am finished.

Thanks for the reply...

No problems. I'm glad to hear the XBox is still working fine.

I used 30 gauge wiring and it installed fine into the BenQ drive, but I have no experience with the Hitachi yet.

Good luck with your next attempt.

I have installed over 100 NME mods, 1.0, 1.1, 1.2 and 2.0 using 30 AWG kynar on all drives, never had an issue!!

[crapoid685]

I am a casual installer. I would have to say I've done in between 50 and 100 mods total. That includes PSOne, PS2, XBOX, Xbox360, and Wii. I know that 30 AWG is the wire of choice, but after I finished my install of the NME2, everything looked perfect and seemed to check out with a voltmeter. All I'm saying is that maybe 32 AWG wire will provide a little more breathing room when doing the A-I points. As for the 5V and GND wires, I was wondering if I should use thicker wire for those points, like I had to do for some PS2 mods, or does the 30 AWG wire work fine?

One to to remember ont he NME 2 did you bridge the point to indicate it is on a Hitachi?? did you install Point M ??  if you did and the install is MINT then you have a bad mod.

OR send me the console to look at and/or proper install

[crapoid685]

If the mod was bad then my console should have functioned properly when I disconnected the GND and Power wires but left everything else intact. Once I completely removed the mod and cleaned up the install, everything functioned properly. This indicates to me that there was a bridge somewhere. BTW, I did bridge the jumper and install the M wire. I am in the process of reinstalling the chip, I will post back this evening with my results.

actually removing power and ground does not make it like the mod was never there, trust me, I have tried this before on dead mods since there is actual voltage still flowing on bios legs it does partially function.  I found this out when trouble shooting the 0078 and 0079 drives before we realized the gnd point for the diagrams are wrong on the official diagrams (only for 0078 and 0079)

Also allot of hitachi drives require you to turn down the laser to 3.0 ESPECIALLY on 0059 drives

I have done allot of NME installs and trouble shooting for people


another issues I have seen is when runing the 30AWG over the top of the SST when you place the bottom cover is comresses the wires and causes excessive noise ont he line, it is best to place the mod ont he bottom of the PCB (laser side) just make sure that your palcement does not interfer witht he laser moving.

typically I put the mod outside the drive right side, looking at console fromt he rear and I run the wires out of the rear right corner (looking at drive from rear) my wires run on the PCB to the opposite side of the epoxy closes to right side

OK... so I reinstalled the chip and I still get the exact same problems. Error 76 on first boot. Does not play any originals or backups. The drive sounds like it is trying to read the disc but it never gets recognized. I checked all points, one by one, with a voltmeter as I installed the chip. I guess the next thing to try would be to tweak the POT(47D drive), but I would like to know if I should worry about the Error 76(it only happens on the first boot after the power cord has been plugged in), before I try to move any further. If the chip is bad then I would like to get a replacement, but I don't know how hard it is going to be to get the retailer to switch out a modchip(especially since I ordered it about 2 months ago). Any help is greatly appreciated.

[crapoid685]

I got rid of the Error 76. So I was under the impression that I could solder both the "USB Off" and "Network Off" features to the chip. Well in the diagrams, both of those points are labeled as "Y". I was soldering both of those points to the one "Y" point on the chip. Once I removed the "USB off" wire and just stuck with the one"Network Off" wire, no more Error 76. I tested a few different types of media and this is what I got:

Original 360 Game: NO
Backup 360 Game: NO
Original DVD (Dual-Layer): NO
Backup DVD (Single-Layer): YES

So my laser will only read single layer DVD media. This leads me to think that I have to adjust the POT. I am moving on to this step and I will post back when I'm done.

I got rid of the Error 76...

Interesting. I hadn't considered this as I only installed the one wire to the network off. However, because I have the "Falcon" (HDMI) motherboard, this feature doesn't work anyway.

Strange that you can't run original games. I'm not familiar with the pot mod for the drive. Have others found that the drive won't function for originals once the NME2 chip is installed? Is this particular to one type of drive?

[crapoid685]

My initial POT reading was 3.2k Ohms. Seems a little high to be straight out of the factory, but I guess it doesn't really surprise me given the crappy quality of first gen Microsoft lasers. I tweaked it to 3.1k Ohms and it still does not read originals. I have not tested a backup yet. I have heard not to go lower that 2.8k Ohms but I have read that some go as low as 2.4k Ohms and get good results. I will keep trying by lowering a 100 Ohms at a time until I get to 2.8k Ohms, then I don't know where I'll go from there if I don't get results.

if your in the USA, send the console to me to look at and I stock NEW lasers, a factory laser is gnerally around 4.1 to 4.8, i have never seen any at 3.2 except when they are dying
