--------------------------------------------------------------------------------
I have been doing some research to make the LG GDR-8164 act like a 8050L (xbox drive) ... I have reproduce all the signals (eject, ready, tr_in, tr_out) and the drive act like an unflashed 8163... nice.
Now yesterday I've received my willem programmer, dumped the FW from a 8163b flashed with 8050l, dumped the FW from the 8164b ( for recovery), and finally fashed it with the 8050l... AND... NO... NO GO... The tray opens as soon as the xbox is powered, closing it, it re-opens right away...I unpluged all the signals wires and the IDE to have power only to the drive and the same thing happens.
Now that you all seem to know pretty well the LG firmwares would you mind looking at it and report if you think that it can be done... I don't ask U to rewrite the entire bin, just if you could give a little help on this that would be great.
If you want to take a look at the files here there are:
LG8050.asm
LG8163.asm
LG8164.asm

I have been tracing the signals to see if a hardware solution is possible, unfortunatly both drives have a different pinout on the MN103 and probably half of it would need rerouting to work...
Now the only solution is to write a new bin file based on the 8050 FW that use the 8164 pinout & routing... Is that possible ?!? if it is...as I think so, is there any chance that you guys want to help on this one ?!?!

Quote: I wonder what do you want to achieve by doing all this?!
Well it's really simple, I am trying to make an xbox drive with the 8164b since Hitachi stopped producing the 8163b.
Microsoft have also stopped producing parts for xbox1... That means that if your xbox drive is dead and you have an unmodded xbox, you will have to mod your xbox to put a PC drive in it, that means no more originals games... only backups... that means no more XBOXLIVE.
This where I am now, to achive this I had to adapt the EJECT, TR_IN, TR_OUT, READY signals to the xbox, to do so I desinged a PCB board to help me...
here is a capture of the PDF file I sent to the PCB manufacturer
On an other hand, if you have a modded PC drive with a xbox firmware (EX.: LG8163 with 8050 FW,Samsung 616t with SDG-605 FW), you can put this drive in an unmoded xbox and still use originals games, that means XBOXLIVE OK !!! This is what I want to achive
Now I am no coder, I need help on this one...I have notice that every xbox firmware request on this board have lead to a dead end...I hope this time it will be different !!!

Yet you all keep posting here. This isn't an XBOX board, and we don't have the man months of time required to do this work for you. We have explained that the GDR-8163B/8050L firmware won't work in a GDR-8164B, nobody listens. When a bunch of XBOX scene people show up here and start patching drives to RPC1 and contributing to our scene we'll be a lot more receptive.
Here are some tips, you would need to create some sort of diff'ing tool to compare the firmwares, there were significant additions to the 8050L firmware, migrating them to the 8164B will be next to impossible without some really good understanding and documentation for the chipset, and some really good tools. We know we don't have the resources to pull this off.
When posting listings that run 7+ MB, use PKZIP
There are still a lot of GDR-8163B drives available.
Sorry to sound negative here, but we don't see much of an upside.

Quote: When a bunch of XBOX scene people show up here and start patching drives to RPC1 and contributing to our scene we'll be a lot more receptive here's a contribution from robinson & macdennis from xboxhacker.net: Quote: Good news, after a long session working with McDennis I can now tell you what is wrong with the Dangerous Brothers RPC1 package and why it doesn't work. Simply, they got the wrong Flash Device ID. So we fixed that and you can find a working 8164B flasher here http://rapidshare.de/files/15747921/8164_LL06.EXE.htmlBe aware that this will complete flashing VERY quickly when used against the same version of firmware and it looks like it's too quick to have worked. Whats going is that the flash programming algorithm has been optimised, each sector in the flash is compared with the new binary and only the sectors which dont match are erased and programmed. So if you flash version LL06 over LL06 nothing happens, lol Quote: We have explained that the GDR-8163B/8050L firmware won't work in a GDR-8164B, nobody listens The bios & window recognize the drive as a 8050l... the problem seem to be more signals routing than other... On the MN103 pin 1-36, 37-108, 109-144 seem to be the same on both drive... finally maybe a hardware way is possible after all ...

I understand your position and thankx for the tips... sorry for the JPG...
P.S. Go to xbohacker.net hacking dvd firmware thread and you will see that a lot of good tools are available for these drives... debuggers, decrypters...and more.

Hi! Dear Patx, can you show a circuit where are EJECT, TR IN, TR OUT and READY points on LG GR8164B?
