NanoVNA bricked

Adrian Waiblinger

Hi all.

I used Dfuse Demo to do an upgrade on the original NanoVNA.
Did as instructed boot to Vdd, switched on and presented with white screen
Fired up DfuSe Demo upgrade to nanoVNA_900_AA, got error message and now I have a white screen after the jumper is removed.
I assume the firmware is gone. any tips on how dot to get this error.

Regards Adrian.
