Help or Suggestions Upgrading to 5.0 or other custom ROM

Hello,

I am new to rooting and never had much success. This is my first successful attempt. I followed this guide

http://forum.xda-developers.com/gala...-2014-t2959613

and now have a rooted 4.4.2 Galaxy S4. SuperSU is installed and claims it disabled knox and Root Checker says I have root. I was able to change the file that disables continuous scrolling successfully but now I have another problem. I keep constantly getting this OTA upgrade notice. I don't know if I should do it or not because I dont know if I will lose root. I would like a bloat free lollipop or other custom rom and am open to suggestions. If you suggest a guide or method the more idiot proof the better because I really can't afford to jack this up.



On verizon, which hates rooting. Not worried about warranty because I have none. Its a used phone off ebay.

Android 4.4.2
Base I545VRUFNK1
Kernal 3.4.0
Build KOT49H.(Base)

Please dont treat me like I am stupid because I already know I am compared to most of you.

Thanks in advance for helpful criticism and suggestions.
