SOLVED: How to flash a WEMOS C3 Mini v2.1.0

I had no problems flashing my C3 mini v1.0.0, but the v2.1.0 would not flash for me. After a lot of research and playing around I solved it. Here's the answer for anyone searching:

  1. Hold RST and Boot buttons. Start to upload the code.
  2. When the code is almost compiled, release the RST button only. You need enough time for the C3 mini to connect to the computer but not too much time.
  3. When this message comes up release the Boot button. (It will have different numbers but the same general idea).

Sketch uses 251952 bytes (19%) of program storage space. Maximum is 1310720 bytes.
Global variables use 13748 bytes (4%) of dynamic memory, leaving 313932 bytes for local variables. Maximum is 327680 bytes.

  1. Your sketch will upload. It may take some practice to get the timing right.
