Flash Several ROMs and

well if it’s stolen, what’s to prevent a thief from taking battery out and then when near a PC, taking sim out, battery in and flashing another firmware wiping out avast along the way?

Nothing can prevent this…
It’s the same as a Windows computer that got formated, or Mac, or Linux…
Or a car that got stolen and the thieve make new keys for it…

thx
