Hello all,

I’m about to give up on this one.
On this page, it gets stuck at preparing installation:

When I go here: https://web.esphome.io/
The esp8266 never goes past “connecting” after selecting "prepare for first use)

My esp shows up as com3

I have also used the same esp on the wled web installer and it works fine.

Can you all give me a bit of guidance as to what is going on? I should be able to provide an additional information on any follow up questions you all may have to help me figure this one out.

This is the nodemcu I am using:

Additional info, hooked up a wemos d1 mini and is worked immediately on https://web.esphome.io/

I have around 10 of those 8266s, so I’m hoping someone can help me figure out whats going on with those or I guess I’ll have to garbage them sadly. :frowning:
Thank you all!

It sounds like you bought ones that have to be put in bootloader mode in order to be flashed. If that is the case, there is a button on the board that must be held down when it is initially plugged it. I can’t help on when exactly to let up on the button because I haven’t had much luck with the couple that I have bought with that feature.

EDIT: Zooming in on the photo of boards from Amazon listing, it does look like yours have the flash button indicated by red arrow. The blue arrow is a reset button.

Yeah, I haven’t been able to figure this out. They are real pains. I am considering junking them. I’ve spent at least 2 hours trying to get them working with the esp website.

I hate to be that wasteful but I’m running out of patience :slight_smile:

Thank you for your reply here @Stephenn

This doesn’t even seem to work.

I didn’t have any luck on that website using Brave browser. I had to use Google Chrome.

I have the same problem. I tried it with offline ESPHome_flasher (1.4.0), it works.

Ahh, was it with one of the Amica 8266s? It has a white background on the backside with their logo. Or was it with another brand? (Blue on both sides probably. Thank you ahead of time for your response.

I got my ESP32 to flash by holding down the flash button (right of usb-c) while plugging in and continuing to hold the flash button while starting the flash process from espweb.

I was running into this exact same issue and was able to determine that the problem was that I needed to change my 2.4GHz wireless network from WPA/WPA2-Personal to WPA2/WPA3-Personal.

After making this change. I was able to connect the ESP8266 device to the 2.4GHz network successfully without getting the “unable to connect message”

Nice. I will give this a try. Never would’ve thought of it myself. Thank you!!!

Hey there, after looking for a long time for a solution I stumbled across a random conversation in one thread (unrelated) and it was mentioned that when it’s in “connecting” state in esphome flasher you should press the “boot” button and it worked. Mine is ESP-32U for reference.
