Use the software recovery tool to go back to Windows Phone 8.1 and try again.

Make sure you have plenty of space free on your device too.

I'm not your bro.

There's no harm in resetting back to Windows Phone 8.1, it usually the easiest way to sort out any installation problems. Keeping on retrying isn't likely to make anything work better.
