Flashing Updated Firmware

Ok, I have a Liteon LTR-40125W overclocked to a 48125W. Now, lets say I flash my drive again with more updated firmware, one that may be incompatible as of right now, would it completely destroy my drive or would it be just a matter of flashing it back? The reason I ask it that I am going to perform some experiments to see if any other firmware will work.

Just a matter of flashing backā€¦

Using MTKFLASH as you cant go back using liteon fw flash. Ive found with mine 40x flashed to 48x that it allows you to burn same discs faster with vs06 than vso2 havnt tried vs08 yet.
