    I found this https://github.com/arendst/Sonoff-Tasmota/wiki/Sonoff-Basic#serial-connection
    They added a wire right to the chip. Does anyone do this, or has anyone tried this before?

      Of course we have done it, soldering pin headers for vcc gnd TX rx is the standard way to get access to the esp8266 to flash it with anything you want. There is no need for the extra wire (but you may need to solder a wire in place of the broken button if you want to put the esp8266 in flash mode)

        I've soldered the connectors. Checked power with a voltmeter. I still only get the RX to flash once, and will not flash the sonoff. Arduino IDE won't even show the Port.

          @joshwizzard are you holding GPIO0 to ground at power on to put it in programming mode?

            @dbemowsk I'm holding the button in before connecting the USB.

              @joshwizzard that sounds correct. What are you using to program it? Arduino IDE?

                @dbemowsk Yes I am. The error is failed to open COM1 and I cannot select a port because it is grayed out.

                  Maybe it's a bad usb serial adapter you have.

                    @joshwizzard if you are using windows, check the device manager. Could be a driver issue. Check for devices with an exclamation point on them, probably under COM & LPT section. If it shows an error 10 or other error, Google your adapter model and the error you see. You should come up with a solution.

                      Are you sure it is COM1? Usually that is the computer serial port, not the external one. Did you set the correct voltage for the Arduino you are using?

                        @gohan I have a USB to serial adapter that is apparently a clone of a more popular brand. I don't have the model in front of me right now, but I had to download a different driver for it to make it work. That's why I mentioned to him to check the Windows device manager. You are also correct that Com1 is usually the computers internal serial port, that is if it has one. Most newer laptops don't have a serial port any more, and Desktops have not come with one in quite some time. So there is the possibility that it could still identify as Com1.

                            @dbemowsk Thank you for the help so far. The first time we flashed tasmota successfully I did update the drivers from the USB converters website and were able to select COM5. We have since tried pogo pins and other USB adapters. I will check everything again.
