Cannot connect after flashing to S3-box.

Ok, I do not know what I am missing here.
I first tried the S3-BOX-lite - it does not prompt for the password. Just display the screen "No WiFi" after a few seconds. My smartphone connects to the wifi ap, but it never asks for the wifi-credentials.
Then I downloaded the github code, add the wifi credentials to the code, flash that and the device goes into a boot-loop, Screen stay black all the time.

Then I tried a S3-BOX by flashing the code from ESPHOME.io/projects. Selected the correct device, but after flashing the wifi-credentials problem is the same. Never asks for the credentials and screen turn to "no Wi-fi" display.
It was picked up by HA integrations, but clicking on "configure" does not do anything, it just tries to connect without any luck. Connection failed
Do I have to connect the device into the Yellow that runs HA or into any PC connected to the newwork?
Even connecting it directly to the yellow that is running HA, does not make any difference.

If you were able to install the firmware from https://esphome.io/projects then you've got a connection to the device and shouldn't need to plug it in to Yellow. Think I experienced something similar upon initial install, but then I was able to just select "Change wifi" on the pop up from the projects site to configure wifi again (after being fairly confident I just had done so after initial installation).

The problem was that I connected to the ESP-BOX3 in "download mode" to flash. That is wrong. Just need to power on and connect to USB to flash. Then it worked.
I used Willow before and it required it to be in "download mode", therefore that's how I was used to doing it.
