Can I reflash BIOS with the same version?

[Lazarus23]

Currently I have a mystery with my bios, first time I flashed my bios was by a q-flash tool inside bios, my last bios update was by "@BIOS" utility inside windows, because I thought it was more convenient. The problem is I think I corrupted my bios with that latest update. The weird thing I noticed recently is when I checked saved bios profiles and saw profiles from way back, before I did my first bios update, now shouldn't the bios update wipe all the saved profiles? Now I start to think that because of corrupted version my bios sometimes switches to a backup version which I created when I did the first bios update by q-flash. 

Loading optimized defaults doesn't work and clearing cmos the same thing. Only thing left is another bios update (definitely by q-flash), the problem is that I'm on the latest version and can only reflash. So can I do it? Can I reflash my bios with the same version?

The big question is should I back the bios up when it asks during flashing, it will back up my current (corrupted) version right? And if I don't back it up, will the last backup remain after flashing?

If you suspect your last backup is corrupted, then backing that up will of course back up the corruption.

I *think* the last (uncorrupted) BIOS will not be overwritten, but you can always make a manual copy to a flash stick of it
