Would I lose unlocked Sim on G510

[Guest peterck]

I deleted some system files on my G510 that I need to have (thought is was blot ware). I've the unlocked Sim (not stuck with Vodafone Sim), I was wondering whether I would have to the unlock Sim again, after I've installed the firmware update to restore the system fails I deleted before. Please help, any suggestions?

A reset will not override the unlocking.
