How do I update to the latest Factory image - No root/unlock full stock

[xJawlz]

I have a stock VZW S5 (Model# SM-G900V) running Android 5.0 (Build# LRX21T.G900VVRU1BOC4). (Last factory OTA update was on April 02, 2015)

I have not had Verizon for some time now so the phone was never used or updated for several years. I would now like to update to the latest factory image that VZW/Samsung sent out OTA.
Where can I obtain the factory image and how would I go about installing it?
I do not wish to root or unlock. I just want the newest factory image.

*FYI* System update does not work from phone settings. (has to be side loaded somehow)

Thanks in advance,
xJawlz

You could just extract this zip and flash the tar.md5 via Odin but it may require you to do a Factory Reset if it hangs on the boot animation or you could install Smart Switch and it will tell you that there is an update available and you can update from there.

If I'm looking to go back to fully stock, could I just update it regularly from the system update? I'm currently on a stock rooted rom Pb1?
