    Sonoff S60 socket

    White Sonoff S60 smart plug next to a gray retail box on a white background

    At the beginning I had a problem with uploading the new software ( here I'm running on Supli ) in probably the 3-4th time it went and started to work, but I want to change something and the problems began.
    At the moment however I try to upload something I get different errors depending on which WEBTool, but it looks like there is an "ESP32 Chip sync error esp_sync_blocking". This is what Flash Download Tools 3.9.10 reports, it looks like bootloader corruption ?. I uploaded it with something like this:

    USB adapter module with capacitor and yellow pin header on a black PCB

    Now I tried with other USB programmers on CP2102 and all the time it looks that TX goes while no RX response.
    How can I unlock the ESP32C3 or otherwise upload something and get it back to normal programming capability ?
    The program that sits there now works and the socket functions, but wants to change the soft.
    I have changed the speeds on the port.
    Please make the instructions :D relatively simple as I know little about programming.

    Pictures and a link from Github what it looks like inside.
