No Schema errors show when booting plus stuck in Apple logo without the progress bar in Lenovo Z50-70 (Big Sur)

I just edited the config.plist using OpenCore Configurator for the WiFi and Bluetooth and this happens. Plus the WiFi and Bluetooth is not working after following countless of tutorials. I followed the instructions in some sites and nothing happens. Can someone help me with this one?
