I've attempted to downgrade from Windows 10 to Windows Phone 8.1 ... and somewhere along the way it got an error and now i'm stucked on a red nokia screen. Has anyone tried to completely reinstall the OS on the phone before?
My phone is Lumia 635.

After trying to restore my phone several times, I was able to reset the phone OS back to Windows Phone 8.1 Cyan on Lumia 635 using the Windows Phone Recovery Tool.
This is url to download the recovery tool -> http://windows.microsoft.com/en-us/windows/preview-backup-restore
