Firmware update crash

When I tried to update the firmware pimax upgrade tool froze and crashed while the headset was flashing red, blue and green. So now it only flash red, blue and green. when I try to use the pimax upgrade tool, it say please click and enter into Dfu Mode, but it can’t do that it does not find it. Is there a way to flash it to factory settings or something else I can do to fix it?

Hmm… I had the Pimax 4k disconnected for 30 minutes and then plugged it in, and restarted windows then everything was normal.
