yes. the board used to work fine before.
i've just tried a diffrent usb-c cable. the other cable does work for my other esp32's fine tho
how can i check?
@anabolicsurgeon I usually go from using Micropython back to enabling the Arduino IDE using the following method
- I pull up the IDE with the "Blink.ino" example
- I make sure I have DOIT ESP32 DEVKIT V1 and the correct com port
- From tools I select TOOLS -> Programmer -> Esptool (should be checked)
- Go to Sketch on the menu bar and Upload Using Programmer
after that it will load normally

You have to read the label on the chip. It's real hard for me to see at 82, but a mag glass and tilting the board until you see it. IIRC one has 340 in it's name, I don;t recall the other but If my life depended on it I would say 210 maybe in the name. I have a Mac so don't have a device manager or whatever it's called.

closed all windows.
opened up ide
opened up blink.ino
enabled esp-tool. (its ticked now)
tried upload via programmer.
output:

Connecting......................................

on the board it says CH340C
All good, it should work. Do you have any other esp32 board if not any esp board to try?

yes, i have. the other identical esp32 works. but unfortunatly i need that one for an other project 
I think you know what that means.

NO idea what those steps are. All I have ever used are Verify and Upload with a processor selection for my cheap NANO clones.

i did the steps, @ sumguy posted at post #23
@anabolicsurgeon that is disappointing that normally works for me every time.
I did notice the error message you posted was trying to connect using COM1 , maybe you could try again and select COM 5 and DOIT ESP32 DEVKIT V1 and double check before trying to upload

Ok, that was for a python to C++ switch or vice-versa I think.

yes. i tried a diffrent port. i've switched to com port 5 again now. the error got replicated
@anabolicsurgeon I have maybe one more idea you could try and that is laid out in another randomnerdstutorial
The troubleshooting section at the bottom quotes the error message that you are getting and explains a possible solution
That's a good idea, I have discovered many folks using the wrong boards URL. For reference, here is what I use. It is the official corporate URL.
https://espressif.github.io/arduino-esp32/package_esp32_index.json
their solution is just press and hold boot then upload then release boot when seeing connecting...
did not work
Just for chuckles, try the board URL I posted in #38
