I'm also using 3,5" tft display but doesnt work

I used spacehuhn webupdater to flash the firmware on my esp32Wroom 
Witht the old firmware but i get a white screen as expected , i saw that you said before that we needed to edit TFT_eSPI but how do i edit that and do i need to flash it then with arduino IDE , platformio or othere things and are there any guides or pre built files available?
This is my screen btw:
