[SOLVED] "Failed to disable echo" PROBLEM

I’m swimming in browser tabs at the moment… would you be so kind as to post me a link to the binary for either the proper Expressif firmware or nodeMCU binary that I can flash? I feel like I am reinventing the wheel just to get my project up and running again…

Thanks in advance.

Edit: I think I finally found some firmwares and manage to flash them (wow finding them was murder).
