One Plus is the newer exclusion in the list of reducing number of new devices in the US which can run Custom ROMs. Right now, I only really know of the Pixel and the Nothing line of mobiles which can run Custom ROMs.
Americans, what are our options?
I believe ASUS phones have an unlockable bootloader - although the app for it currently doesn’t work (several month long maintenance?) but is estimated to work again sometime Q3 of this year
Thanks, I’ll keep an eye out
