ESP-01S not broadcasting SSID #Solved

[luiscesjr]

I'm having a bit of trouble setting up my ESP. Some background on the history of issues:

I was using Octopi, but suddenly it stopped working on my router. New octopi images, new boards, tried everything, it did not work, so I had to reflash my printer fw to be able to read from my SKR 1.4 turbo board sdcard, which was not enabled before.
I found my ESP 01S that came with my board, and thought about adding it to have a bit of the octopi's features, and after the initial setup all was alright.

The problems started when I decided to go from AP mode to connect to my router, the same octopi problem happened, and I could not access the ESP anymore. I decided to then erase the ESP flash and install again the ESP3D onto it, but somehow it's not working anymore, it just won't broadcast the initial wifi.

I am able to erase it and install again, tried different ESP3D versions, but results are the same. The monitor on Vscode gives out nothing really, so I can't know if it's having some issue.
It stays like this:

Any ideas what I could start from to look for a solution? Thanks!

So after trying to esp flasher and the vscode hundreds of times, I decided to try the Arduino IDE, somehow there it started working again on the latest fw of esp3d. I have no idea why there it finally started working, but it did. So if anyone ever face the same problem...

I started by uploading a blink led to check the board was functional, and then dug through the configs to get my board up and running again.

if after flashing an esp8266 there is no brodcast neither serial output it usually:
1 - flash size defined is wrong, esp8266 does not raise error if you try to flash an 1MB flash but you set 4MB flash
2- rarely the Flash mode must be changed on esp8266 from dio to another
3 - on esp8266-01 be sure the pins CH_PD / RESET / GPIO 0 et eventually GPIO 2 must be high after flash https://github.com/luc-github/ESP3D/wiki/Hardware-connection#esp-01
4 - depending on ftdi adapter a restart may be necessary after flash to match the point 3
