I bought a brand new oculus yesterday, just my luck facebook goes down. Before that though I'm on the line with support trying to get my phone to detect the headset so i can use the mobile app (it was detected on start up but lost it somehow after headset updated).
After trying everything support asked me to factory reset the headset.
This is when facebook went down, since then I have not been able to access anything inside the headset without connecting it to oculus link on PC. the headset has no apps (maybe expected after reset) the store doesn't work, nor the browser no the explore option. The settings reports no updates available. I have tried resetting the device again but it doesn't help.
With mine being new I'd had enough of going through support and brought it back to the shop for a replacement, if yours is still under warranty suggest doing the same. Even out of warranty this seems like an issue they should fix for you as you've been left with a brick through no fault of your own....
