It's the update, not your device. It's in an eternal loop. The update is faulty, not sure why it's still being released. There's a big discussion on one of my posts. My advice. If the update keeps trying to install, do a back up and factory reset, it will bring you to v78.0 and will stop trying to send the update constantly. Switch off auto update and keep an eye out for v79. A couple of times the failed update appears, it looks like it updates but it doesn't, but it doesn't happen continuously. I'm on V78.0 with Navigator (appeared after factory reset). Now I'm just waiting for v79. I can't say you're going to have exactly the same result but it will stop the daily frustration of seeing these failing updates. Btw, the Meta Quest Software Update option with USB doesn't work. I tried it a few times. Don't waste your time ๐
