A few days ago, I was able to get the unit into DFU mode and it was
recognized in Device Manager. I installed the latest Firmware and was still
getting a white screen. At the suggestion of another post, I left the
analyzer off for a few days with the battery disconnected. I powered it
back up today with the results that it now shows in Device Manager and I
was just able to run a calibration through NanoVNA Saver but the screen is
still white.

This sounds like you may have a defective screen issue. I recall others had this problem and opened up the unit and checked the solder connections. Some cured it by gently re-soldering connections.

If you are going to use it as is with a PC program use NanoVNA App. It will use raw uncalibrated data during calibration while Saver depends on a calibrated NanoVNA. NanoVNA app also does firmware flashing. If you are new to nanoVNA app see my previous post on it >>>/g/nanovna-users/topic/91143866#28096
