I’m having an unusual problem when I try to flash my firmware in my Samsung SH-222A DVD burner, I keep getting a ‘Flash cmd fail’ error message, I’ve tried using both Tsdnwin.exe and sfdnwin.exe to flash it using a patched firmware (I know the patched firmware is good because my other SH-222A drive (purchased at the same time as the problematic one) accepted it just fine once I used the -NOCHECK switch). I have tried making a custom bootable USB drive with a copy of FreeDOS on it along with the sfdndos.exe file and both the original unpatched firmware for version SB02 and the patched firmware as well, neither one worked even with the -n and the sm (secondary master, which is indeed where the drive is) switches specified, the program finds the drive without any problems but reports a failure message similar to the one I get with the windows based flashers.
I’ve tried using both windows based flashers even to try to flash back to a previous version of firmware (unpatched version) with no luck, even with the -NOCHECK option. I have even tried all of the mentioned windows flasher methods in safe mode too, again with the same ‘Flash cmd fail’ error message being displayed. The odd thing about this is that the drive is still functioning just fine for the most part even after the failed flash attempts, the reason I wanted to update the firmware was in the hopes that it would help fix a couple of problems I’m encountering from time to time when I burn a disc (CD OR DVD) where the session never closes, I was also hoping it would fix the issue with not being able to burn at any speed lower than 4x for CD’s (every once in a while I need to burn utility discs for various PC repair tasks and I prefer to do so at 1X because I’ve had problems occasionally with discs burned at higher speeds booting in some systems).
Would appreciate any help on this matter.
PS - before anyone asks, I’m not on a system using a VIA chipset, both of my computers have Intel chipsets, and I got the same failures when I tried installing it in my other computer. Have also tried changing drive jumper from master to cable select and back with same results. Like I said the other drive identical to this one updated just fine, but for some reason this one won’t.
