Hi
I have a NanoVNA with version 0.8.0 firmware Dated June 2020. Is there a later version for this early NanoVna?
If so are ther some instructions somewhere. I did this in 2020 and it seemed straightforward but I seem to be struggling to find the right info at the moment.
regards
Don

Roger,
Thanks for the link.
It doesn't look like my original Nanovna needs updating.
I assume that the updates for the later versions would not be suitable.

0.8 is an extremely old version.
This should work on your device:

In case you were worried about "bricking" your device, don't be. It is
practically impossible to do.

If you do not have the version 0.8 as *.bin (or *.dfu) file I would propose to save it from device before you flash the new version. Dunno how to do it on windows, on linux I use "dfu-util -d 0483:df11 -a 0 -s 0x08000000 -U old_version.bin" to save (upload) the old version to the PC (128 KByte). The tool dfu-util works also for Windows, it is available e.g. from Erik's website together with the manual
