I just finished doing that and now I am getting the 1603 error.
I looked it up and it says
Follow the steps listed above for Error 1604. Also, discard the .ipsw file, open iTunes and attempt to download the update again. See the steps under Advanced Steps > Rename, move, or delete the iOS software file (.ipsw) below for file locations. If you do not want to remove the IPSW in the original user, try restoring in a new administrator user. If the issue remains, Eliminate third-party security software conflicts.
the thing is I do not have any security software on this PC to begin with I am uninstalling iTunes and renstalling it again before trying one more time.
I disabled windows firewall and run itunes diagnostics and I got the following report.
