I'm looking to buy one of these phones but I'm not sure if I'll be able to install LineageOS on the Pro1X. The fxtec website lists it as an OS, but the Lineage website only has the Pro1, and not the Pro1X. Is there too much of a difference between processors, or will it work for both models? Is it even possible to buy the Pro1 from here? The buy button for it just links to the Pro1X...
