    This usually means the controller firmware didn’t actually finish flashing, even though it says “100%”.

    Try this:

    • Remove the battery for at least 5 minutes
    • Put in a fresh battery (brand new, not rechargeable if possible)
    • Open the Meta app → Devices → Remove controller completely
    • Reboot the headset
    • Pair the controller again from scratch

    If it still shows blank firmware and won’t power on, it’s likely a failed firmware flash, and you’ll need to contact Meta Support directly
