\*\*How to Install 5GHz & 2.4GHz OLED Display D.eauther on RTL8720DN BW16 | Step-by-Step Guide

But when i plug in the USB C to my Board the red LED activates. So i asked myself why is that. Turns out i probably have to erase the firmware or default software on the board. I did all that and it still doesnt work. Not even the blink test works, altough my board is recognized and the upload is successfull. Can someone please explain ELI5 how the get this done. I am trying since 3 days, it is just frustating at some point.\*\*
