Facebook has released an unlocked operating system for its Oculus Go headsets that allows users to run their own software on the device. This new OS stops the headset from signature-checking the boot.img, meaning users are free to replace that with whatever they wish, granting them unrestricted access to the headset. Of course, this also removes the necessity of using a Facebook or Oculus account with the device. However, the process is irreversible, and you will no longer receive over-the-air updates after you've unlocked the OS.
This move comes about a year after Facebook discontinued the Go line, and shut down app development last December. While there will still be firmware and security updates pushed to the Go until 2022, this unlocked OS should allow users to support the device indefinitely.
