Yeah the fix is a few threads down. I truly doubt its related to the front panel, at least for the "Please Insert..." because in the box that I had that had the issue, I hadn't connected the front panel at all when I tested it.

[Heykrop]

Same boat here.  

I got mine from modchap.ca. Connected it to a Hitachi 0078FK and DID NOT use the Network or LED connections. NOW all I get is an ERROR 64 WITH or WITHOUT the chip installed.

Nah. Your problem is a bad install(er), not a bad chip - since you get errors without it also. I'm betting you had some short somewhere that ended up frying your firmware.

http://forums.xbox-s...howtopic=589582

I would tend to agree with you on that if it werent for the fact that I did the install myself under a microscope in a board servicing lab.

I dont know about the network point, i've never used it.

as far as the LED point. in my last install i was getting no backups to boot, so i put the LED to see if the chip was activating...it was not. I removed the coil but not the LED wire and all was well. So to say it IS the front panel connection isn't 100% right.

What would *I* do?

Install the chip as is. If it doesn't work TEST EVERYTHING. Laser - proper solder - wires - shorts - i would even start all over even using new wire if need be - also make sure the backup works (I know my backups work because I have my own personal xbox with a nme1.1 chip and they work in that)

*IF* I still get errors. Then I would try removing the 470 and replacing it with a wire.
*IF* I still get errors. I would try what NME suggests.


I'm not sure what 'remove 47 and put to 5v' means. I dont think english is teamunderdogs first language.
It could either mean what we've been doing, removing the 470 and shorting the pins out. *OR* remove the 470 and place it in between the 5V point and the wire that woudl go to the 5V point. As people with Hitachi DJ drives have to do using the 220 coil.

and from what i've read and encountered personally. the 470 doesn't cause E## errors. It causes a "Please insert this disc..." error. If you're gettin an E## error, something else is most likely wrong. Could it? Maybe, I haven't done enough to see. But from my personal experience, it causes the disc to spit out "Plesase insert this disc in an xbox 360 console".

but the chip does not overwrite your firmware. when its turned off its the same as not having a chip at all and your drive being stock.  when its on it patches the firmware with what it needs. but doesn't overwrite anything permanetly.

Are some chips bad from a lot? Yeah. There is such a thing as a dud chip in every batch. but I doubt you have it, and if you did, i doubt it would permanetly screw up your drive.

i think something shorted out and corrupted your firmware.I'm sure your a competent tech, but lets face it the nme1.2 hitachi install is a bitch. the points are so close and they need so many wires. a short could have happened anywhere and you may have over looked it..it happens.

thanks for the advice ydgmms....got one more question though.....I saw the video of removing the glue with the heat gun.....It doesnt look that hard to do.......it looks much easier to go that route because the soldering looks like it would be much easier job to do on the chip rather than those tiny leads with the alt points.....is there a reason for not going the route of the heat gun? im not arguing with ya.....I'm just curious  and trying to figure out the easiest thing for me to do is.....thanks again.....

It depends on the drive.

Does your drive have the black epoxy? If so, it may be easier to heat up the chip area(careful not to overheat the chip itself) and chip just enough to solder a wire to the pin.

Yeah its easier to solder to the pins, they're bigger.

If your drive just has the white epoxy, I wouldn't waste my time heating/chipping the chip area. when for me its easier to scratch off the green board layer and solder to the copper.


Its all up to you. I know what I can and cannot do.

[goofy173]

I tried the heatgun on the black epoxy and I saw no change in the goo. However it was fairly simple to scratch off the stuff from that one pin on the chip to solder to it.

I would also be careful in heating any epoxy/glue stuff on boards as some can have cyanoacrylate in it and it will form cyanide gas when heated.

When I heated mine I was using a biohazard fumehood.

[ydgmms]

You wont see any change...it will however be easier to chip off.

Ok. So my Xbox started to act funny a few days after installation. Everything works but when I booted up, it give me a E76 error.  Knowing the E76 is a network error, I de-solder the network cut-off connect wire.  It works fine again every since(2 weeks, knock on wood).  But I notice when the Xbox 360 booted up, the center power led is not lid up.  So it must be in NME mode?  But when I put a original game in, the center led lid up.  So I guess why I have the error message due to the chip starting in NME mode upon bootup cutting off the network.  Therefore, it's working in opposite of what it was design for but it still works. Or am I misreading this because I didn't take notice of the original xbox 360 before modding it.  Does the center power led light up when a xbox 360 powers up without any original game in the drive?

I did not have any luck with backups until last night. I finally got a copy of Sonic to work, but only once. I never could duplicate it again. I have the Samsung drive. The one time it worked I had the NME 1.2 chip board connected as they suggested, except I had a jumper across the 470 inductor. I turned the XBOX off and then on again to confirm it was working. I haven't been able to run a copy again. One thing I noticed is that when the copy worked, my power light was still on, even though it's connected as specified.

At least I know now I have everything close to right and the NME's firmware is still intact. Now if they can just get it straight but I don't have any hope of that. Who's responsible for a refund? The seller I bought  it from or Team Underdog?

I'm tired of having to rework the NME and I'm going to use something else.

[ydgmms]

the seller would need to issue a refund. If they don't - point them to Team Underdogs site where they say specificlly there is a problem with the chips.

That's where I'm headed then. I can't believe they released these unchecked with all possible combos.

Hi,

I'd read the whole thread, and i had only registerd to ask this little question:

My problem is that my nme36 1.2 doesn't work like it should. I've doublechecked all the wires and of course tried some other (and im not a trainee in soldering, i'd done a Hitachi nme360 mod before and it works!). I soldered this da*n chip to this Samsung Drive so many times i don't even count any more, i thougt the Samsung would be very easier. I failed and this is keeping me awake every night.
So right back all i get is a Power LED which only stays at OFF and any backup i try is playing this DVD Video.
If i connect the network point i'll get an E75 error (there is no SMD at the soldering point?? Hitachi has got one).
If i disconnect the LED wire the LED stays at ON but all i get ist this da*n video.

Today i read your very interesting guide in which u tell me to bridge/remove the 470 and don't connect the network point if i get only DVD videos. I think i have to try it, now its revenge time, i'll get this!

Unclear for me is (excuse me im german, and my english isn't that good) remove and bridge the 470 or should i try to first remove and test and if it won't work all the way i should bridge it?

Simple said:
-Bridge and remove?
-only remove first?

What would you do?
Thank you!

P.S.: Please excuse my bad english and the other stuff  

[ydgmms]

remove. solder wire in its place - as per the guide.

Just a update. I desolder my led connection and the xbox 360 bootup on original mode like it suppose to. The led stays lit. When I put in a backup it plays fine. If I go from Backup->Original, I need to shut down and bootup again to play Original.  However, if I go from Original->Backup, no reboot is necessary. So in conclusion, the led connection does effect the operation of the chip. If you have the led connected to the chip and if the power(center) led doesn't light up, you are in NME mode (not Original firmware mode) after bootup! Just becareful.
