Hey drivembig, how's it going? Good I hope. Glad to see you comment on this. USB huh? That sounds cool. 8) Do you know what the drive uses the 12v for? I ask only because obviously the USB will not provide that. If you would like a peek at the schematic I'm basing my next project on click
HERE. Keep in mind he started his pin numbering with 0. This should never be done, but if you look at it you can figure it out rather easily.
I have sourced the voltage regulator he uses, and found it for just over $1 USD. I will be adding a switch DPST for main power (killing both +5v and +12v), a switch SPDT for eject(would like something w/ 1 momentary position), leds for power and eject, and of course a probe for the Lite-On drives all laid out on a perf board. :wink:
Sorry I don't have any pics or diagrams yet, my kids have been keeping me pretty busy lately. So I have yet to get the regulator and switches. I hope to order them this weekend and get things going early next week.
I have come up with a design without using the regulator, but it leaves the eject in the floating state I mentioned in my earlier post, and it is not really good practice to do it that way. Yes it will work, but you take a chance at harming the drive. As this has become a "just for fun" project now, I would rather build it correctly.
Hopefully I'll have some progress to report back on soon.

XBOX360 Lite-On Key Retrieval and Firmware Flashing
PC Freezing? Sata ports not found? Can’t dump Lite-on Key? Look no further. This article will help solve your troubles.
After banging my head off the wall for countless hours which led to days of aggravation and failed attempts to retrieve my Lite-On drives key.bin, inquiry.bin, and identity.bin, I finally found the information I needed.
I found no matter what software I used (iprep, jungleflasher, extractor reader, etc) or what operating system I was on (windows, or dos), the guides and tutorials all used the same basic procedure. This is not their exact wording, but the procedure is the same throughout.
1. Power on PC and boot to DOS or Windows. (depending on which application your using)
2. Connect sata cable to Lite-On drive. (opposite end is already attached to PC)
3. Power on Lite-On drive.
4. Use Geremia’s DVDKey method to prepare Lite-On for key retrieval.
4.1. Eject Lite-On tray.
4.2. Power of Lite-On drive.
4.3. Push tray by hand half way closed.
4.4. Power on Lite-On drive with tray half closed.
5. Retrieve key, inquiry, and identity bin files through your preferred application. (This will depend on the guide you are following)
Every time I tried it failed when done in that order. In Windows my Pc would freeze after step #3 “power on Lite-On driveâ€, and in DOS it would fail to retrieve the key (why the sata had anything to do with the key in dos is beyond me. As we all know the key comes in on the com port). So I tested my probe (how to later), if was functioning fine. At this point I could not explain why it did not work in DOS. Then I decided to look at Windows and why it was freezing. I found some people saying to uninstall the drives for your sata controller (I use a VIA 6421) and let PORTIO32 take care of it. I thought this sounded weird, but figured at this point I had nothing to loose. When I did this none of the applications Windows or DOS based could see my sata ports. Exactly what I thought would happen.
After some more searching I found a small post on some forum. I don’t remember the forum or posters name, but he gets all credit here. It is so simple just, use the same procedure as before except skip step #2 and do not connect the sata to your Lite-On until you have it readied with the tray half closed and powered on again
.
Here is the exact procedure I found to work 100% of the time.
1. Hook all hardware up except the sata cable to your Lite-On drive.
2. Boot to DOS or Windows. (Depending on application being used)
3. Power on Lite-On DVD drive.
4. Eject Lite-On tray
5. Power off Lite-On drive.
6. Push tray halfway in by hand.
7. Power on Lite-On drive.
8. Now connect your sata cable from your PC to your Lite-On drive. If in windows and it still freezes, give it a minute. It will come back now.
9. Now you are ready to follow any guide/tutorial you like.
Just remember your drive is ready for dumping/flashing.
DO NOT, repeat Geremia’s DVDKey method (ejecting tray, power off, push in, power on) from your guide/tutorial. Just skip that part.
You will not need to touch your drive again until…
1. You probe the R707 VIA and
2. Power cycle the drive before erasing the original firmware.
Again remember, everything else is done inside your chosen application. DO NOT, eject or power on/off the Lite-On drive until the erasing procedure tells you to.
