I found a site online to reinstall KitKat (android 4.4.4). Hopefully it works and I can get rid of Lollipop. *fingers crossed*
I just don't want to do it if the auto-update will cancel out all that work.
Changing the manufacturers software is called rooting, and it voids your warranty. The best option is to fix any issues you are having with the new software. If you are having problems, run the Software Repair Assistant.
