This is absolutely cracked. I've been with OnePlus since the One, also getting the 2, 6 and now I have the 12. Stuck with them all these years because I really respected their - original - take on device freedom. I really should've seen the writing on the wall given how much pain it is to update it in the first place, as I have the NA version which only officially allows carrier updates, and I don't live in NA (and even if I did I'd still not be tied to a carrier).

Now I have to consider my device dead re updates, because if I haven't already gotten the killing update I'd rather avoid it. First thing I did was unlock the bootloader, and I intend to root/flash it at some point. Will be finding another brand whenever I'm ready to upgrade again.
