I'm trying to go back to Windows 8.1 from Windows 10 but it does not seem to work. I tried doing recovery through Settings. Reset PC resets it keeps it on Windows 10. Doing recovery gives me a blue screen error (see picture 1). I also tried to download the surface pro 3 recovery image (SurfacePro3_BMR_10_3.4.1.zip) from Microsoft. Their instructions says to extract the .zip file into a USB drive and try booting from it. It gives me this black screen error (see picture 2). I tried calling Microsoft support about this and they have no idea what went wrong and suggested I goto a Microsoft Store for support (none is near my house). I got a feeling I'm overlooking something. Any help is appreciated. Thank you.
