?Welcome to the forum, Ted.
The Nanovna and Nanovna H use the same firmware. The Nanovna H4 uses different firmware that is not compatible with the previous 2 due to its larger display and different processor.
Please practice using DeFuSe to install FW on your unit. You cannot brick the Nanovna...if an upload fails, just start again.
Edy556's FW is stable as is hugen's FW.
Only install DiSlord's FW if you're looking at experimenting with his releases.
Read at least one or more user guides found in the files section and review the forum's wiki for useful info.

Hi Guys (and Gals) Newby here with a couple questions:
Just got a new NanoVNA-H4 from Amazon and am working my way into
gaining a bit of proficiency with it. I notice that the firmware is
somewhat dated considering the rapid development curve. Ver info on my
unit is below:
11) Looking through the site I note the latest edy555 firmware
upgrade is ver 0.8.0 released 6-19-20. Is this compatible with the H4
version? Upgrades since my ver 0.5.0 encompass many of the features
being discussed now so I figure it is wise to upgrade.
22) I let my computers auto install the drivers for both my WIN 7
machine STM ver 1.3.1.0, and WIN 10 laptop MS USB Serial Device ver
10.0.18362.1. Both seem to interface OK with NanoVNA-Server 3.40. STM
site says upgrade ver STM-32102 doesn't work with WIN 10 but to use
the "in Box" version which I am assuming is the windows embedded
driver as noted above.
So far I am most impressed with the advanced capabilities of this
very (unbelievably) economical unit, providing measurement capability
typically far beyond the range of the average techs budget. If I had
any up front observations, I would suggest some real world thought to
ruggedize the unit for field use. Such as in the use of metal
enclosures or at least frames to connect the SMA connections to a
solid support rather than the delicate PCB connections.
