My P10 plus is rooted, Normally i can't get system update, so I try to update manually my Android system from nougat (vky-L09c432b150) to Oreo (8.0.0.360) international update, I try it by 2 methods normal update via TWRP and by forcing update by extracting update. App to dload folder on SD card and reboot in erecovery mode to auto start the update process, but unsuccessfully. So guys, what is the good method to execute any new update.?
