LITEON 93450 Weird replacement liteton drive

[BreAKDoWNs]

So my friend, who does 360 console repairs at a local mom and pop shop, received a shipment of replacement DVD drives that he uses to fix broken DVD drives. Over the course of several years he has received 100s of various 360 drives and all have worked perfectly, however this one drive that came with several others on his recent shipment is different. To my understanding these are all new drives, not used or refurbished mind you. The one drive that I mentioned earlier has two soldered wires pictured below (sorry image quality is so low, click to view bigger picture)


Here is a more descriptive representation of the four solder points. If you click on the image you can see it in much higher quality.


As a side note he claimed he tested it on different 360s and it was able to read and boot discs without any sort of spoofing and/or flashing. I don't know how accurate this is as it makes no sense at all, however I haven't dumped the firmware yet so I haven't ruled out that possibility yet.

Oh and I have been googleing and searching for the the answer and haven't found any sort answers yet. So please if you have any sort of knowledge on what this exactly is, please I'd appreciate hearing back from anyone.

Looks like a track repair to me, and if its playing backups then its been flashed / modified

as for testing it on different consoles without spoofing / key changing, wouldn't work
(just play dvd)

anyways a fw dump would be the way to tell, or a vid of it being tested without spoofing would be cool too. I very much doubt it tho

 

[BreAKDoWNs]

Sorry to my knowledge it can only play retail disc and not backups. I'm about to do a full dump now, I'll post what it says soon. And I never heard of a track repair before.

What does the otherside look like, can you take a photo?

 

[BreAKDoWNs]

Just like a normal 93450c-2 should I upload a picture of that?

EDIT: I dumped the dummy file, it looks like its stock can't really tell much else. Would it be best if I uploaded the dummy file, as I don't really care who really sees it I'm just going to use this board as a test for soldering if I can't find out why these wires are soldered on.

EDIT 2: Also i can't really test the fact that "it reads on other xboxs regardless of firmware" as the wires we're de-soldered from the drive and I'm not really a pro a soldering so he'd have to re-solder it back onto a drive to get final verdict.

Track / Trace repairs are done on many electronic devices for repair.

Between point A and Point B the track / copper is broken, so Point A and B can be rejoined by wire.

Hope it answers your question m8

 

[BreAKDoWNs]

Oh ok that makes more sense. However the board is basically brand new, and has absolutely no signs of damage nor needs of repair, plus aren't the two tracks spread really far apart to be that kind of repair? Also it might be worth mentioning that the solder points holding the two copper cables down appear to be done by machine not by hand.

 

[n0syst3m]

These pcb's are multi layered (correct if wrong) so the points could be any were, as for the machine soldering i highly dout it m8, looks like a normal solder job to me. (13 years experience)

Some tracks are less than 1mm m8 the track fault is sometimes unnoticeable

Only explanation i can think of.

 

[BreAKDoWNs]

My first picture is really misleading as its way to blurry, however that's the best picture I could get. :mad2:

Is that the only possible explanation though? I'm ok with accepting that as a perfectly possible solution, but I'd just like to explore other possibilities.

But I don't get one thing, if it was a track repair then wouldn't the two solder points be closer than having one point on one side and the connecting point on the other, shouldn't the wire be shorter and the two points connecting the copper wire be alot closer together?

 

[xbox360 hacker]

Remove wires then flash it to work in a drive. If it fails to work then you can be certain they were added to repair broken traces Then all other theory's can be left alone

No it doesn't matter about distance :facepalm:

I sugest you learn about electronic repair and soldering.

I understand what your saying and i'm giving you the correct answer ffs. This forum is full of pro's waiting to help u, best keep your cool

I really doubt this is MS repair or sum kinda special ONE in a Million PCB, that completely breaks down everything that is known and been learned by the scene.

It is always best to join two solid points together if it is available, rather than scratching at the pcb and ruining the track any further.

I blew my ck3 pro up once, really browned it, but instead of joing the track together either side of the break, i just found the two terminating end point and joined them with a wire. It is so much easier to solder and more stable

Sorry I didn't mean to sound ignorant. And I have been trying to learn about soldering and board repair. I have been trying to learn how to do and know all this kind of stuff, just still a newbie.

And Microsoft didn't do the repair, it came from vendor that resales these drives. And I thought it might be unique because of the claims that it can play on different consoles with the same firmware. But I understand this would need substantial amount of proof, and I just can't give that right now until it gets re-soldered together. Which I guess renders this topic invalid for now. I'll post the response to that if in fact it has some weird firmware.
