As of 2023 there are many badly performing clones on the market. V2/3GHz NanoVNA uses parts like ADF4350 and AD8342 which are costly and clones have been cutting costs by using salvaged or reject parts.
See official store and look for V2 Plus4/V2 Plus4 Pro versions only to avoid getting a bad clone. We have stopped selling V2.2 versions since October 2020, so all V2 hardware that are not Plus or Plus4 are not made by us and we can not guarantee performance.
It seems bricked, it worked a few months ago when I put it on the shelf, today I charged it up, turned it on and ...white screen, Win11 gives USB error.
Any ideas?

Hi, can you tell me what error message it shows? Can you enter DFU mode by turning it off and on while holding down the left button, and see if the USB device is recognized in DFU mode?
Thanks
Thank you for the reply!
Holding the left button while powering up gives the same Win11 error that just powering the nanoVNA with no button:
*"USB device not recognized...The last USB device you connected to the computer malfunctioned and Windows does not recognize it"*
White screen on the nanoVNA, unresponsive to any button. I really appreciate your help! I was going to use the nanoVNA in my RF repair business.
