Building your own Lite On probe - guide with pictures

I am so sorry! I forgot about this...
The thing is, I can't seem to find the transfer cable for the camera.

I got frustrated and I decided to look on Craigslist for someone in my area who flashes. Found a guy who will do it for $25...

You should change your name to MacGyver. Great tutorial, but I hope I never end up with one of those drives. You guys are great.

 

Believe it or not, I ended up with a liteon after sending it in for GRAPHICAL repairs.
Totally out of the subject of my repair, they replace my drive.
M$ sucks.

 

While the LO is a little more involved when it comes time to flash it, I actually prefer it over other drives. It's nice and quiet.

 

I agree, I like the LO cause of it being quiet. The only downside is it was a pain to mod compared to the other drives!

 

Haven't seen one yet.. sure to give this a try and report back when I do tho.

 

I finished the cable and after 3 tries finally noticed the transistor was backwards so I started it again and tested in HyperTerm for the symbols (they all come out when I brush the Tx cable with a 5 volt source) but for some reason, I can get the other 2 files but not the key itself. I tested both, the resistors and transistors afterwards with a multimeter and they all seem fine... I seriously don't have any idea of what else to do. I am targeting the R707 hole using a needle as point. Do I have to clean the hole first or something (it does seem to have some extra silicone covering some of the metal area)

I've only tested with JungleFlasher... I'll try DOS at some point this week.

 

I don't have a CK3 to be used for the 5v power source. Where would be the best place to acquire a 5v power supply?

 

Are you talking about powering the device or the drive? For the drive you can just use the 360 Power. For the device, you can just plug it into a Molex on the Computer to power it.

 

I figured as much but, aren't some of these molex' 12v?

 

nevermind. I figured it out XD

 

hi, hm, how can i test if my thing is correctly setted up before trying it on.

i bought this transistor at radioshack

would this one work? or do i have to buy exactly the one in the tutorial.

i got my 5V power from the FLOPPY connector, you can actually remove the cable from the white thing then just clipped it to there. (RED CABLE is 5V Black is Ground, Orange is 12v DONT USE ORANGE)

i connected it to the back, clipped the power and turn on the pc, i get a measurement of -.99 V on my tip that goes to the drive. i checked my cables in multimeter to see if they were misplaced but they were correct, why do i get -.99v??

am i suppose to get a NEG or POS measurement, also whats the measurement that should be at the tip (that goes to the drive)

this is my cable that i made..

LOL PIC PENDING, had to put my cam to charge.

in the mean time can you guys tell me if that transistor that i used is good? and the measurements for the tip.

i used 1/4W resistors 1k for power and 10k for tip

 

this is my work of art lol, why is it not working? what am i doing wrong.

when i use dvdkey32 i get BAD data serial or something like that, then extract aborted.

in red letters.

 

okay, i got it, had to change my NPN transistor to the one in tut, mine wasnt the one, extracted keys flawlessly =)

 

This works and it works great and i really thank the uploader i spent the 30 dollars i saved on dual layer disks.

and not to bring a old thread to life for simple thankyou.

I had a problem i CHECKED everything the cables the solder work hell i thought i broke the transister anyways my problem was i soldered too far on the pins and they didn't stick in the serial port casing far enough to make the connection so i took that off and stuck them straight onto the pins on the back of the computer took me a day to figure that simple part out after replacing everything once or twice.

I also scraped at the pinhole with a needle until you could see copper in my non working delerium another revision i used a small saftey pin don't know how the pen spring worked since i didn't have it working at that point.

also I may be retarded with the multimeter but my red molex was showing around 10 volts and it still worked fine.

one last thing is i had two com ports and didn't know which was which you can match the IRQ's you should be able to see what your serial port is in the bios and it should list the IRQ then match that in device manager.

 

Thanks for the great tutorial. Built the probe, with minimal experience, and dumped/flashed my Lite-On in no time.

 

Nevermind. I succeeded getting the key and flashing the drive without much effort! I wasn't opening the drive half way properly lol.

Thank you very much for this awesome guide. It's much simpler to follow than the X-scene one.

 

Glad it worked for you guys.

 

Could you guys please upload pics of your builds?
Im trying to source a transistor from some old electronics.
Anyone have any ideas on the best places to source?
thanks

 

You should be fine as long as you don't use one of the bigger power transistors (the one in the diagram a couple of posts above).
