[QUOTE=Zibri;2785115]This is the firmware of GUD1N can anyone make it region free? then I can try a crossflash because I think they are the same drive.
You shouldn’t assume that GUD0N and GUD1N drives use identical hardware. This is generally/historically not the case for most slim LG drives. Quite often there can be major differences between successive families, and historically speaking LG are well known to quite often alternate between different chipsets (Renesas, Panasonic and Mediatek) from one family to the next. Crossflashing without knowing for sure that two drive models are hardware identical is a dangerous enterprise and a sure way of most likely killing a drive for good.
In fact I had a look at the two firmwares and these two drives couldn’t be more different! GUD0N uses a Panasonic chipset and a 2Mb firmware, while GUD1N uses a Mediatek chipset with a 1Mb firmware. It cannot get any more different than that, and that historical pattern proves to be true in this case.
As for the GUD0N firmware, I have processed your raw firmware dump (added the necessary header, sorted out the checksums and removed all the rubbish data from the raw dump) and obtained a flashable firmware for you. I can’t test it since I do not have this drive, but standalone flashers recognise the processed firmware correctly which means that the structure and all the checksums are correct, so this this dump should work just fine.
I have uploaded a copy for you here: http://www17.zippyshare.com/v/IdnNgFhY/file.html
As I said in one of my earlier posts, having a flashable copy of the firmware is not particularly helpful in this case, because MCSE doesn’t support these drives and therefore you can’t use it to patch these particular firmwares. Furthermore, while I am able to create a flashable firmware from a raw dump, my knowledge ends there. Disassembling firmwares and firmware patching is above my pay grade I’m afraid
So I’m afraid that as far as RPC patching goes, the only chance you’ve got at this stage is using a software like AnyDVD to bypass regional protections.
For reference, in addition to the now flashable dump that I have created from your raw dump (firmware v1.00), there’s only one other GUD0N firmware available that I know of, namely the HP OEM SD03 firmware. I have extracted the binary from the HP flasher, and I included it in the above archive. I have also included a copy of a standalone/unlocked LG flasher that will allow one to flash these firmwares to a GUD0N drive.
Needless to say, none of these are of a particular help (unless someone wants to play with crossflashing between the two OEM firmwares that is) without someone who can patch these firmwares, and as Albert said, I don’t think we’ve got any firmware patchers around that are still active and can patch these firmwares…
Also, there’s no good reason to crossflash a (presumably retail) drive coming with firmware 1.00 on board into an HP OEM model that uses firmware SD03. The reason is that the firmware dates of the two firmwares are quite close, in fact firmware 1.00 is nearly two months newer than SD03. Firmware 1.00 is dated 15/07/30, while firmware SD03 is dated 15/06/09.
For someone who has an HP OEM GUD0N drive, they might have more of a reason to crossflash it to the retail model though. As HP OEM drives identify as “hp HLDS DVDRW GUD0N” that would suggest that these drives probably lack DVD-RAM support (i.e. this feature is disabled in the HP OEM firmware) and therefore by crossflashing they will ‘upgrade’ their drive to the retail model (HL-DT-STDVDRAM GUD0N) which supports DVD-RAM and which is also nearly two months newer. This would be pretty much the only crossflashing benefit that I can see.
