If i am running on USB power only (no battery installed), might this be causing the issue?

you’re just missing the path to esptool, it is running on the script.

What’s best way to reset esptool path, i.e. what’s the correct path in order to run?

Thanks for that, tried with another few cables and now my error is

Error putting ESP in stub flash mode: Failed to write to target RAM (result was 01070000: Operation timed out)

Is this a writeable issue?
