DVD Firmware problem...



New Member
Samsung DVD SD-612
Previous Firmware - 0.3

*Downloaded (flashed through WinXP) firmware SD-612 v0.3u; DVD worked like usual
-Downloaded (flashed through WinXP) firmware SD-612b v0.5
-DVD light flashes once when computer turns on
-Light doesn't blink anymore after powering computer
-Tray doesn't operate
-System BIOS does not detect the DVD anymore nor does DOS, Windows XP, or the flashing utility in dos and windows. (sfdnw2k.exe, sfdndos.exe)

-Firmware is either corrupt or -wrong model-
The flash was very slow took about 5 minutes
(comparable to 1-2 minutes for the other flash)
-Seems to power off after initializing when system turns on (drive is inoperable)
-Unflashable in result to powering off**

>Is their any way to resolve this problem?
-Get it back in working condition
-Loading the appropriate firmware back on
>Is their any jumper settings to reset firmware?
>Do I possibly have to purchase a new (firmware) v0.3 EEPROM and replace the old chip with it?

Sent the same problem to Samsung tech-support, just seeing if anyone on this forum can shed light on this problem. Any suggestions are welcome. Thank-you for your time.

Bios flashing is always a risk, but I'll ask the obvious first.
Have you tried flashing with the previous version? If you have and it's still NFG then replacing the chip is about your only option (if you can get one). Other than that it's DCM.

Yes I've attempted to flash with the previous version. The flash program doesn't see the DVD drive though.

I think I may try to replace the EEPROM chip or find someone with a EEPROM writer. What's the price range of a firmware chip?
