It is the same concept on an iPhone, you have 7 days to downgrade, then it is permanently impossible. Not for technical reasons, but because of an arbitrary lock (achieved through signature).
OnePlus just chose the hardware way, versus Apple the signature way
Whether for OnePlus or Apple, there should definitively be a way to let users sign and run the operating system of their choice, like any other software.
(still hating this iOS 26, and the fact that even after losing all my data and downgrading back iOS 18 it refused to re-sync my Apple Watch until iOS 26 was installed again, shitty company policy)

There is a good reason to prevent downgrades -- older versions have CVEs and some are actually exploitable.
