I have the same error, also with an ESP32 MiniKIT V2.0 from MH-ET Live. Have you found a way to fix it? Also I have tried to use an external FTDI Adapter but without success as well.

I managed to flash it using the following setup:

  • an external FTDI Adapter
  • IO0 connected to GND
  • 2.2 uF Capacitor between RST and GND
  • USB Cable plugged into a separate power supply

if you have the error on macos, you can try this: https://github.com/WCHSoftGroup/ch34xser_macos
