Security wipe running 10.2.1.1055

I have a Z10 running this leak and I want to give it to my GF for Christmas (I have a Q10 and a white Z10 that I purchased during the Thanksgiving special) .

My question is if I perform a security wipe, will this leak still be the OS, Or will it revert to th AT&T Official OS?

Thanks in advance for any help!
