The only way I was able to upgrade to Lollipop was through my Surface Windows 10 PC. To do so you must download the Samsung connect software for Windows, and the drivers so your PC recognizes and communicates with the Verizon Note 12.2. Once set up, use the Windows interface to check for available tablet upgrades, and Lollipop 5.1 is instantly found. Once you've clicked to accept the upgrade your PC does all the work of upgrading for you. Also, If you have Outlook installed on your note tablet, the software can also transfer and set up Outlook with all the email accounts you use on your computer, and the Windows program allows you to backup your tablets apps and files in case you ever need to do a complete system restore.
