Wow, that’s thorough. Yea, we could definitely use a good set of instructions.
You can also just update the files from the WebUI itself.
I posted this recently as a simplified set of instructions and files.
Also note that if you have the 8MB V1E ESP32 and want/need more than 192KB of Flash storage, you can build/upload with PlatformIO. Then you’re not using the web installer at all. You end up with 1.77MB.
Mitch’s repo is latest. He made a bunch of changes to consolidate the code between v2 and v3. Last I checked, selecting files within folders that I fixed was broken again. I kind of lost interest as I don’t use that extension.
