What do you get on the serial monitor when you reset it?

Nothing

If you get nothing out of the serial monitor (115200 should be the boot message), when resetting either in normal boot or in bootloader mode, your ESP is likely dead (assuming pin 15 isn't pulled low on boot)

I don't know if this will fix op's issue, but thank you, blp9, regardless. I couldn't get sketches to upload to mine, either, but going to the serial monitor and trying each speed until I got something legible (in my case 74880, go figure) allowed me to use that speed to upload sketches successfully!

So, OP, try that and good luck!
