#78185 I am trying to flash custom firmware build and downloaded from, using PyFlasher by Marcel Stör. I am using Lolin NodeMCU V3.
Problem is PyFlasher get stuck after a few lines in console. I waited for hour but nothing happens.
I tried changing the USB port of laptop the NodeMCU is connected, changed cable, changed baud rates, tried both options “Erase Flash” from ‘yes’ and ‘no’, but no success.
How to get out of this?
