Is B1/B2 visa still valid if it got changed into F1 status?

Hello everybody,
I'd like to make sure that B1/B2 visa is still valid. I changed B1/B2 visa into F1 status, and l left U.S for my country.
So now I am thinking of travel to U.S with my B1/B2 visa, and i do not know it is ok or not. Does somebody know it or is there anybody in same situation like me?
Please thanks in advance.
Tranto.

Hi, based on what you have written I see no reason why your B visa should not be valid.
