Use oxygen updater from play store or XDA developers
Oxygen updater isn't safe. One of my friends updated from Oxygen updater and then he got stuck in some kind of mode ( like fastboot ).
Oxygen updater use OnePlus servers,so it's kind of a mirror thing,so it's safe.
Tell ur friend to download a full update.
Okay so, I will tell him back. Anyway thanks mate.
