Downgrade from high sierra to sierra

Hey,

I was trying to downgrade my macbook pro (early 2011) from high sierra back to sierra. I downloaded sierra and i made an usb installation disk. Then i deleted high sierra from my mac and when i was trying to install sierra i got an error.

The error is this one:

the operation couldn\U2019t be completed. (com.apple.PackageKit.PKFileDownload error 5.)

Is there someone who had the same problem and who can help me with this?

Thanks 🙂

MacBook Pro, macOS High Sierra (10.13)

What exactly did you download, and how large was the installer file? How did you delete High Sierra? Is the installer in your Applications folder? How did you make the USB flash drive installer? Read How to Downgrade macOS High Sierra and macOS Reversion- How to Downgrade from High Sierra.
