I am having an issue with using TSDNWIN myself. I am trying to flash a TS-L633N 0300 drive on a HP laptop running Windows 7 Home Premium. I followed the first 5 steps from this thread:
OK, there's bad news and good news ...
The bad news is that there doesn't seem to be any OEM firmwares out for the TS-L633N at all ... worse still, since your drive is an HP OEM the chance of getting a firmware update from HP any time soon is rather slim to none (reason being that HP rarely provide any firmware updates for notebook drives)...
The good news is that the TS-L633N is an OEM version of the SN-S083N retail drive, and Samsung has just released firmware SB02 for it in mid December, so if you're willing to void your warranty for the drive (assuming your laptop is still under warranty) you can crossflash your drive to the real thing, and make it RPC1 in the process

You won't be able to go back to the TS-L633N firmware though, since there is none available and there's no way to dump the existing firmware from Samsung drives.
If you want to go ahead with the crossflash, this is what you need to do:
1. Go to Samsung and download the SN-S083N SB02 firmware:

2. Download the Samsung stand alone flasher:
http://www.samsungodd.com/KorLib/File/tsdnwin.exe3. Download ala42's MCSE:
http://ala42.cdfreaks.com/MCSE/4. Extract the SN-S083N_SB02.bin firmware file from the Samsung flasher you downloaded by using WinRar/WinZip
5. Load the SN-S083N_SB02.bin file in MCSE, click the RPC1 box and save it as SN-S083N_SB02_speedpatched.bin
6. Start the tsdnwin.exe flasher from a command line with the -nocheck parameter: tsdnwin -nocheck
7. Once the flasher opens, load the speedpached firmware in it and then flash your drive.
8. Reboot when asked and enjoy your new RPC1 drive!
When I get to step 6, I can't get the tsdnwin to start via the command prompt. I am not terribly experienced with DOS prompts but I did a directory search for .exe files and it didn't show up. So my question is, do I need to do something else not listed here? Any info is helpful.
