Updating LG Fathom firmware will lock it again?

I purchased it like that.
I didnt put any unlock code, just put the SIM, changed the mode to GSM.UTMS and it started working.

But might be the seller here has unlocked it before selling becuase I have read somewhere that phone does not detected GSM SIMs until its unlocked.

On the other hand, when I select CDMA mode and put my CDMA SIM, it does not detect and hangs, so I feel like its still locked, but not sure

I don't think it will work with CDMA SIM cards because it wasn't designed for them. It will work with any GSM network, but only Verizon CDMA networks.
