What are the side affects of downloading DVD ROM firmware

I cannot booktype my DVD+Rs to DVD ROMs using my DVD recorder. So I used google and found a firmware that will help my Pioneer llld and make it work. But I also read that it can have bad affects on the rest of my computer. So I come down to my question... If something did go wrong would I be able to system restore back 1 day and have the firmaware gone

 

you have a 50 50 chance of success.I tried to up the firmware on my dvd rom and it failed miserably.My motto goes, if it aint broke dont fix it..

The moral here is i had to get a new one as it turned out the firmware i put in locked it up

 

Thanks zeiram, I guess I won't then

 

it may still work but it was gurnard who gave me the info on that my drive was 3 revisions out so when i upgraded i had to change both burner and rom

 

I have upgraded firmware about 30times since 2000 in 6 different drivcees and didnt screw up you ussualy get a benefit ussually better compaitbilty and if luck a speed boost my DL in the samsung went from 2.4x to 4x

 

that doesnt seem to be much of a benefit, was it really worth it considering you can burn at 16 x
