Brent,
Please browse the forum Wiki and Files sections.
You will find PDFs and links to various User Guides that detail the flashing process and other neat stuff about the nanovna.
plese remember - you CANNOT brick the Nanovna. If the flashing fails, you just try again.
Please ensure you use the correct family of firmware (read the wiki) for your unit (H FW is only for H and earlier units, H4 FW is only for H4 units)
Regards,Larry

Thanks, John. I thought it might be something like that. And I've learned a
second thing from your reply, how to update the firmware. Is there a
specific site or download I need to be connected to?

Brent,
My NanoVNA has a couple of circuit pads at that location (VDD and BOOT0).
When shorted together at power-up, they cause the NanoVNA to enter DFU mode
for firmware update.? I suspect your unit has a switch provided to provide
that function without an added jumper wire.

I'm a new user to the group. I did a search on the topic but was unable
to
discover what the small momentary push button switch in the center of the
right edge of the nano VNA does. None of the online videos, etc. seem to
know
this control is there. It doesn't seem to do anything when I press it.
Any
ideas?
Thanks.
