problem with firmware update for nanovna v2

Scott KF7GGN 2021/09/10 16:38

Hello, I am new to the forum. I have a NanoVNA V2 that was bought from Amazon, so probably one of the cheap clones that are discussed on the website. I experienced a problem when attempting to flash a firmware upgrade. Upon switching on the unit while holding down the left JOG button and releasing, the white screen remains frozen. Is there a way to fix this issue?

Thank you in  advance for any help.

Hi Scott,

I made the update with the NanoVNA-QT software without problems. No buttons have to be pressed with this method.
