Security when buying a second hand PinePhone

[PineniP]

So, unless the seller hasn't bothered trying out firmware installations, this will definitely have been played around with.

I haven't opened a PinePhone myself so I don't know if there are chips whose firmware requires physical disassembly that will be somewhat tamper evident. Obviously some tamperings won't be evident and I know that's the point of the PinePhone.

That's why I asked if there is a way to reflash the various firmwares in the phone or at least compare hashes with other users or with official hashes on the website.


So my questions still stand.
