dude, if u have a chinese phone - u can only install chinese stock rom and lock BL, if u have a global phone - u can install any stock rom except chinese rom and lock BL. hope this helps.
if u r good, dont update. google has implemented a new security fix - to check the phones are BL locked r not and some other play integreity api fixes. they are tightening the security.
just a question ,will the update from stable rom to hyper os will be OTA or format required. (if we dont have magisk and dont care about google pay ). Please update. thanks.
lol. it will never b fixed. ita security implemented by google. use magisk r use physical cards r go back to stock roms. these 3 options, choose 1. no choice.
