Downloaded wrong Firmware & Restore function

My system has come with the following Drives:

HL D T ST DVD +/-RW GSA-H31N

                         &

HL DT ST DVD ROM GDR H10N

 

 

Now, I had flash the following firmware intended for HL D S GSA H31N [+/-RW]

I did create a restore point just prior to doing that Flash.

 

I learnt from a thread that a wrong Flash can damage the hardware.

 

Now, can anyone tell me if I use the restore point that created just prior to the download, will my system revert back to previous level, so that my hardware does not get damaged.

 

Thanking you for your help.
