Firmware upgrade troubleshooting - checklist/procedure

Very good list, certainly useful for beginners like me!
I don't know if it is relevant but when i wanted to update/connect through USB I had to install the USB driver manually. Mine called FTDI driver where VCP or D2XX are types of drivers. With one of the two it said it was installed but still i coudn't update/connect.

Great list! Thanks for making it, definitely should go into the documention.
I'd add making sure you have nothing connected to the board other than the serial, power and GND-G23 connection.
In particular disconnect anything on the strapping pins:
G16 / P9 • MTDI/GPIO12: internal pull-down
G15 / P8 • GPIO2: internal pull-down
G24 / P3 • GPIO4: internal pull-down
G11 / P4 • MTDO/GPIO15: internal pull-up
G12 / P5 • GPIO5: internal pull-up
