Hi Erik
My fault!
I tried to upload the firmware, using the usual tool,but found the fw was not readable...
So I simply made it readable - 'now there's the problem'
It then did something and now my dear NanoSA has a white screen only...
Can one reboot it like the old NanoVNA can, by shorting the two pins - hope so!
How can I restore my NanoSA back to normality? Help
