[Sprint  Galaxy Note 4 Q&A, Help & Troubleshooting] samep:
It's as simple as:

Odin OB7 stock tar and Odin TWRP. Flash ROM. Get stock tar and Odin from link below. PC driver will be at Samsung mobile support for Note 4.

TWRP recovery for Odin:

But the 3 things to consider or note before you begin:

1) if you update beyond OB7, the bootloader gets upgraded to one with a reactivation lockable bootloader. That will prevent you from being able to Odin back to KitKat. You need to disable auto update and stop the update notices before they start; otherwise the nags persist and you may accidentally update.

2) the lollipop file system is different than KitKat do better off formatting your data and wiping cache and dalvik-cache and powering down and pulling battery prior to Odin OB7 stock tar. Let it boot and setup wizard prior to Odin of TWRP (uncheck auto reboot for recovery flash only), boot into TWRP recovery and flash the ROM.

3) dalvik gets built on initial boot of lollipop ROMs; the stock tar still not much quicker. You'll likely see the phone hang at the second boot splash screen with blue LED slowly blinking before you see the app optimization and app start pop-ups. You can expect that with lollipop. Give it 30 minutes to boot before you panic. To avoid CPU heating and slowing the process, remove your phone from its case and ventilate if it gets too warm. You need to start with battery charged to about 80% to full to be safe. It's best to not try and update apps or restore apps until you've flashed and booted the custom ROM. More apps means the process takes longer. You can format the data again prior to flashing the custom ROM to speed things along. If possible, backup your media, and downloads that you want to keep and wipe internal sdcard to get a cleaner start with lollipop. That's optional but don't lose your keepsakes. What you flash should be on extSdCard to avoid the wipe-loss if it.

BTW, the post you're referring to may have been an attempt to recover phone after attempting to downgrade to OB7 or KitKat. It's since been discovered that although Odin wouldn't downgrade, there's a possibility to flash older ROMs in recovery and immediately flash a 5.1.1 rooted kernel to get it to boot without looping. That doesn't have to apply to you; the general rule is to Odin flash the tar that matches the ROM you want to flash in recovery. But again, if you upgrade beyond OB7, you cannot go backwards with Odin. Only few exceptions apply; generally it is forward, not backwards. OB7 is the divide that separates the simple from more complex conditions. So these last 3 paragraphs shouldn't apply to you as long as you're wanting to stay with OB7 or KitKat.

Just for an idea of what to consider in other lollipop updates. The ram optimization got a bit crazy after OB7 and continued until it improved in OJ6. Personally, I think OJ6 and OK1 updates are the best lollipop updates yet. You'll certainly find more security updates in those updates. But lollipop 5.1.1 also introduced the need to root the kernel but Chainfire has recently brought us a patch to use stock kernel again; it's married from experimental to beta. I've mostly ran with stock kernel on my phone, especially before lollipop 5.1.1

Long post but felt the long threads needed some explanation. Things were once simpler but got a tad more complex as time and updates followed OB7.
