The Firmware Page

I am trying the same winhex methods from this thread: viewtopic.php?f=13&t=46473&st=0&sk=t&sd=a
to crossflash my Matshita BD-MLT UJ-230AS with OEM firmware 1.23, it currently has Sony 1.11 firmware, and the OEM flasher says the device is not connected. I cut the firmware out of the update file into a separate firmware.bin file successfully, but had to experiment to figure out how long the firmware is until it was the correct length. I then get a checksum error. The MatshitaFlasher recognises that the firmware and drive are a match, so I must be doing something right at least...

Drive: MATSHITA BD-MLT UJ-230AS

Laptop: Toshiba Qosmio X300-15T

Drive origin: Ebay (apparently taken from a Vaio laptop, as it has a Vaio laptop model number written on in permanent ink)

Firmware 1.23 (OEM)
http://121ware.com/support/download/005 ... s_v123.exe

Firmware 1.11 (Sony Vaio)
http://rapidshare.com/files/448864807/U ... O_V111.exe

When I open the updater files, they do look very similar, and the drive model matches. Don't know why the OEM updater claims the drive isn't connected, but the Vaio one works (well it did till I last updated, it now says the firmware is already up to date of course)... hence trying to cut the firmware out of the OEM updater and manually update with MatshitaWinFlasher.
The OEM firmware seems to start at offset 00157696, and end at 01329552. I figured that out after the flasher kept saying "does not match header info" until I cut bytes from the firmware.bin file until it matched the right size. Or am I doing something wrong here?
I wouldn't normally bother with such a task, but I keep getting "calibration errors" when trying to burn Dual-layer DVD's. The same media burns fine in an older DVD-Multi burner, so I can only assume that the Sony firmware I'm stuck on is a bit junk. Strange! Does anyone know what I can do to correctly extract the OEM firmware with winhex and flash it to my drive?

...and why do you create another thread with the same topic then?

Because that thread concerns a different drive, I thought it would be thread hijacking..

I have the same model got from eBay, any news?

That info doesnt give us any clue.

If you want to get help and help others too, provide some drive details at least.

Sorry mate, I'm still stuck myself. Just so you know, I did try the opposite way recently- as in cutting the firmware out of the OEM update program, and hex-pasting it over the firmware in the Sony update program. I tried to run it and it said it's not a valid Win32 application . I'm just going to leave as is for now until there's some way of reverse engineering the firmwares. I know it's been made possible with older drives, just not this kind yet! Patience!

EDIT: Actually, please could you do a DiscInfo report? It may well be useful to see if you have a different firmware version on your drive. If yours is a different version then it might be useful to someone if you could extract it and it could be compared to differing firmware.

I don't have such a drive.

We just need more users which participate here and then this goal is easier to achieve.

Please can you use DiscInfo to make a report for us? http://discinfo.rpc1.org/
Use the screenshot button on it and attach it to this topic. We can go from there and if the firmware version is different it could be useful to take a sample of it using MatshitaDumper. I already have managed to extract the firmware currently on my drive, and it would be useful if I had a different version to compare with.

Here you go, hope it helps.
I will try the WinDbg method as mentioned in the other post, see if I can cross-flash the NEC 1.23 firmware to my drive.

Did you find any solution in order to upgrade the drive to 1.23?Thank you

Why would you do that?
The 1.23 is for SONY OEM drives only.
