getting my replacement mk 808 today

[SolidMetal]

Hi all, i am going to be getting another mk 808 today, the last one i got messed up and i tried everyhting i could from going over the forum and nothing would fix it, so i sent it back and i have another one on it's way today, what i would like to know is, when i get it should i flash the firmware when i get it to the latest one or just leave it as is? i did not get the chance to flash the last one because of the issue i had with it.
also i see different firmwares for the 808 how do i know if its a 808 or a 808b? i don't want to flash it with the wrong firmware and mess this one up.
thanks
