into a nanoVNA-4?
I have the dreaded white screen after attempting a firmware update. Reading past postings indicates that I need to load DMR-CLEAR_MEMORY_DFU.dfu
My PC no longer sees the vna, therefore "Available DFU Devices" in DfuSe is blank and nothing can be selected. What step(s) am I missing?
Tnx/73,
