So I successfully installed the developer preview a few days back so that I could try out Android P. I then proceeded to downgrade my phone from Android P to Android O (Stable build). I was able to downgrade it but now I can't seem to connect it through ADB. It does show up as an MTP and also as an ADB device but that's it, it doesn't show up in CMD or in PowerShell. Can anyone help me out with the drivers? I have the drivers Nokia provided on the phone but its useless as the Setup.exe won't start.
