I'm pretty sure all version 0.2.3 firmware have the battery icon which I don't
see on your photos.
This icon disappears if voltage on the pin is below 100 mV. So, you can get picture with no battery if diode is not installed.
Regarding to the edy555 firmware, there is some difference with hugen79 firmware:
1) hugen79 firmware has imbalance gain correction, which is missing from edy555 firmware
2) hugen79 firmware has a little different logic for frequency band/gain change.
3) hugen79 firmware has correct default touch calibration, which works ok with NanoVNA-H hardware even with no touch calibration. edy555 firmware has different default touch calibration which is incompatible with NanoVNA-H hardware, so you're needs to calibrate touch screen after switch to the edy555 firmware.
