Trying to run Sequoia on a late 2012 Mac Mini but the wi-fi stops working and the graphic patches create a bug

A month ago I bought an old mini so I can develop in xCode. Internet tutorials led me to use OLP to update the little dinossaur to use Sequoia, which works fine until the firmware updates take down my internet connection. Seeing as the OLP recommends installing the Graphics and WLAN patches, I tried that and now the screen is completely black and I can't even see if my connectivity issues were solved. Does anyone else face these issuee?
