I have problem with Lite-on 16D4S 0401 Winbond. I successfully dump it by slimkey, do kamikaze (spi status 0x03) by dremel (I already do by this method some about 5 drives without fail) read it, compare keys from 2 reads and write LTPlus 2.0, then lock-it.

After assembling xbox, slim drive don't see any disc, dash writes only "Open tray" like without disc.

JungleFlasher see drive and do any task with this drive (just for test purpose I unlock drive again, dump it, write and lock without problems)

I double check every ribbon and drive engines (spinning engine and this one for moving laser) and I start to suspect laser because I don't see any blinks from it (should I?) after re-ejecting tray with disc.

Do I think correctly? Please help.

check to see if laser cable is fully in the port it connects to and other cables as well

Try leaving the drive unlocked as well...for some strange reason it performs well unlocked

Checked.

Even checked every single line in ribbon via multimeter and clean contacts in ports and ribbon with alcohol.


Doesn't work.

I even risk looking into laser lenses (not directly, but in some angle), there is no signs of light anytime !

The strangest in this laser problem is that it was disconnected when I was doing: read, unlock, write and relock.

I'm starting to suspect that maybe static electricity kill laser when I touched ribbon of it.

Have you tried outro'ing it a few times? Can't say i've ever that problem with my 0401, but i am using a tx pcb..

wrong post

Tried outgoing several times, without success.

I even replaced laser, and still nothing.

Can I replace board from other slim 0225 with spoofing it to 0401?

Board replaced and problem solved.

I checked again measurement of drilling point on broken board and everything seems to be fine, but apparently isn't.

I had a similar problem, found out I had broken a trace around the f/w chip whist removing the epoxy, maybe have a closer look.

I didn't remove all epoxy. I don't see any damages.

Here are photos of this board that didn't give light on laser but anything else is working right:

I wonder if you accidently knocked off a cap or resistor? The trace that was my problem is located at the bottom right corner, the last pin/leg of the f/w chip. And in your picture it all looks ok to me also.

EDIT:
Looking at your picture again I've got a feeling you only marked the point 7 pins down. You might of cut slightly above where you should of.

as far as I know, go down 1mm too deep you get this problem... you butchered the chip bud!

But chip seems to works good (it locks and unlocks, you can dump it, erase and write).

On this photo You can see how big is drilling point (I used dremel with 0.8mm). I don't think that I drilled to deep.



I don't see any absence of cap or resistor.



That marking isn't perfect, and I took a correct when I drilled.
You can see it on this photo.

Try this, use a knife/blade or something thin and sharp to put between each pin/leg on the f/w chip and make sure they arent touching. Thats about all I have got on this, failing that you have messed up the chip. I find that using something that is blunt works better in a dremel a few times ive used a polishing wheel screw/shaft. You have to push harder but it doesnt cut fast so gives more time to stop.

Just thought of something, did you double outro the dvd drive?

Bingo , the board is alive, laser give light and I have a spare board . Thanks mate .

Cleaning this legs helped:


As far my drilling skills are still 100% success .

Glad you got it sorted matey.

Im having the same exact problem. Same drive, used the maximus template and stopped drilling the second it turned to 0x00 and I have used this template and method on plenty of other drives and didnt have any issues. I tried doing outro several times and that didnt help. I would take the advice that helped this guy except I didnt remove any epoxy or even touch it in any way so how can I make sure the legs are separated? If anyone can think of anything else that can help it would be appreciated. Thanks.

Same here, same issue, disc will not spin, everything else works just fine.


I didn't remove the epoxy so I don't see how checking that can help, but once I get a heat gun I'll check it out completely.


Any other recomendations or a rebuild diagram like the eject issue?

exactly the same issue here, although i did not touch the epoxy. i will remove the epoxy and see what i can come up with.
