Especially since it’s unclear which FW version you need for which ESC hardware; vesc tool auto detects it making things easy.
Also hilarious that there’s no V3.00 branch in github, you have to cross check the release date if you want to be sure 
And make sure the firmware you need was actually built and pushed for that version.
@YUTW123 if trampa continues bothering you about it, you can clone / provide a download for variESC Tool to make your changes, since it has all trademarked logos removed
