 pF> It makes them "Unbrickable", at least as far as I've tried.    :)

This is a smart thing, kinda like how some OnePlus mobiles have their ROMs, my OnePlus 6T has 2 sides, A and B.

I don't know if I can choose which to boot from or upgrade - but I doubt by now the stock ROM exists on either as it's been running LineageOS for some 5+ years at this point so I'm sure it's swapped and installed over many times lol.
