from this point on, anyone who says

1. when will the firmware be ready
2. how can i get a new system without a liteon drive
3. what drive is in my system
4. does anyone have the ability to contact c4e directly
5. can we just flash the lite-on with the benq firmware
6. something stupid/useless/not constructive

you WILL have your post invised and your account put on a 7 day mute. if you are unsure about if your post is going to get you in trouble, post it Here.

this being said, i just want to explicitly say, those of you posting the c4e irc logs, great work. those are actually useful and give everyone a straight from the horses mouth update.

*MODERATOR UPDATE*

Please review This Post for the latest news regarding the status of this drive.

Hi today i recieved a console back from microsoft repair center in Australia, it had a BENQ drive which didnt seem to flash via dosflash. Apon inspection i believe i have found a new drive revision!

Model no. DG-16D2S
HW Version. A0A1
FW Version. 74850C



I would be willing to loan/donate the drive to C4E, if he would like to contact me about it via PM
Cheers

Have you tried to dump the firmware with dosflash ???

Have you opened it.... A picture/scan of the pcb might indicate if it completely new or just a revision...

Dosflash doesnt read, it gets to the usual y/n to resend commands. Hit Y it will do the normal 51/D1 when I cut power and turn it back on, then the code changes to 52/D2 and will not read. I have flashed manier Benq before with no problems, Here is a photo of the PCB, which confirms a new model

What's more I don't see a flash device....

I doubt it, but is the board double-sided... any parts on the bottom side

No parts on the other side.... as you can see theres clear epoxy around the MT1319L chip which would indicate where the FW is stored:) although im no hardware expert
Also noticed the manufacturers are Phillips and Lite-on, not Phillips and BenQ like on the VAD6038

MT1319L is the drive controller, similar to the MT1359SL that is on the BenQ drive.

Can you take a clearer pic of the top and bottom of the board please.

Thanks,

Caster.

Can you also take a picture of the tray.

Also, the drive functions perfectly fine in the console, correct? Plays originals fine, etc...?

Thanks,

Caster.

Here are some more pics, Yes i know they suck..
New BenQ

Edit: BTW The tray is the same as a Benq

It's quite possible this has an MCU (Multi-Chip Unit) with the flash embedded; it's also quite possible it has an OTP (One Time Programmable) area for the serial with the firmware integrated instead of on embedded flash, especially if it's designed specifically for the 360 (this is something I've always laughed about, using a generic PC drive arch. in a "next gen" machine instead of designing the drive more tightly into the security chain.) Though, to a degree, I can't see them bothering to add epoxy unless it was still vulnerable in some way.

What if the chip manufacturers and Microsoft just made a BGA chip. Then you couldn't get at the pins w/o a shit load of work and effort.

Compare the DG-16D2S model number with this Lite-On drive. I bet that this drive might just be the next kreon drive.

Can't see them using a BGA package in an effort to stop modders... Those BGA packages way are more expensive than the TQFP, you would only use them where space is an issue ( like 3g ), space just isn't an issue on this PCB and the 144 pin pincount is too low...

nice find.. anyone have this drive?

Yes. This drive has a MT1309E controller and has an SPI flash.

So, different controller than the drive above and Samsung/BenQ drives.

Ok guys some more small findings. I tried mtkflash (+ 10 sec trick) no read, not recognised in windows, its recognised by slax as 16D2S during bootup, thats about as far as i can get.....

[HotKnife420]

Looks like an SPI similar to the BenQs we've come to know and love hold the fw. Deduce which leg of the SPI carries the power to the chip, and try lifting that leg and soldering a switch. From there, try dosflash/mtkflash.

ya it could be a "write once" chip so it gets married to the mobo in the factory

If they did that, they'd only make it harder to fix any systems they recieve. If a chip would indeed be write-once, they wouldn't be able to re-marry a drive (in the event the mobo died, but the drive was still good). I'm pretty convinced that the 360 having a more computer-like essence is saving MS a good chunk of change (compared to if the console was designed more like a PS2).

My theory!

the controller chip looks like on Samsung SH-D162D drives (MT1308E IDE) or Asus DVD-E616A3 (MT1309E SATA) drives, the SPI ROM is now inside the MT1319L.
I think this is the major difference, so where is no problem at all!! the drives are still flashable.


btw. The same move you will see at Hitachi/LG GDR-H20N (MN103SD6FDA SATA) PC drives. the 256kb flash is now embedded.
who knows, maybe we will see soon new HL v90 drives


Samsung SH-D162D




Asus DVD-E616A3



Hitachi/LG GDR-H20N
