Need help please...
I've already done a Factory Reset, and still 'Updating' stopped at 38% every time.
Each failure happened right after a few beeps on my Windows 10 PC, so it seems it failed right after the goggles/device reset/reconnection step.
What do I do now???

OK, just checked and found the firmware on my fpv goggles is the latest, so it seems it was the [Refresh] function kept failing. No harm then.
