Joomla Error 500 Workround/Fix for 3.7.5 to 3.8.0 Update

Today I updated Joomla to version 3.8.1 from from the 3.7.5 version. Update method I used was, downloading the upgrade zip and extract. 

Result I got was a blank administration page (in blue) and blank web page. 

However I was able to get the site up with following steps:

Note: Make sure to take web root and SQL backup before proceeding. 

Step 1: Apply the 3.8.1 upgrade by unzipping the upgrade zip to web root. (You will see blank pages and blue admin page)

Step 2: Rename the 'libraries' folder in the web root to 'libraries2'

Step 3: Download version 3.8.1 full package and unzip it to some where else (E.g. To your home or your temp directory).

Step 4: Go in to unzipped full package and copy the 'libraries' folder with all content inside.

Step 5: Paste it to your web root where 'libraries' folder was before renaming. This will do the trick.

As my understating Joomla has gone some Architectural change from 3.7.x to 3.8.x.  Some file locations had changed and unzipping upgrade file will not remove the old content. Having both files together creates redefining some variables over again and problems.
