Resolve an issue where the built-in latency tester randomly stops working After the update finishes, shut down and restart the Oculus Configuration Utility. Select a file (e.g., Firmware/DK2/DK2Firmware_2_12.ovrf). Select Tools > Advanced > Update Firmware. Connect your DK2 and make sure that it shows up as connected in the Oculus Configuration Utility
Although the DK2 headset ships with firmware version 2.10, it must be updated to the latest firmware version.
