Okay so you download system updates from asus website for Asus rog phone 3 strix edition model. You copy to internal memory and restart the phone. The system will detect updates itself.
If you have the tencent edition, what software do you have? WW? If you have WW firmware, did you only check OTA update? Please try to download the update from the asus rog phone 3 strix edition support page and put it in the main folder, then restart...
