Sprint recently rolled out an OTA update with Factory Reset Protection and some bug fixes to the Galaxy Note 4, build number being N910PVPU2BOE1.

Factory Reset Protection is essentially a security feature that locks the bootloader on your phone so that nobody could factory reset your phone without your authorization. It’s a simple toggle under the Developer options titled as “Enable OEM unlock”. 

Google introduced Factory Reset Protection with Android 5.0 Lollipop, and also implemented it to Nexus 6 and Nexus 9. But it’s only upto OEM and carrier partners to decide if they want to put this on their devices too. So far, only Sprint is actively pushing out updates to its Samsung devices with FPR.

With Factory Reset Protection enabled on your Galaxy Note 4, you won’t be able to flash custom binaries to your device like a custom recovery or CF Auto Root. But thankfully, FPR isn’t a complete lockdown. It can be disabled from the settings and then you can go do your normal business with Odin and all things root, recovery and custom ROMs.

After taking the N910PVPU2BOE1 OTA update on your Sprint Note 4, root access on your device must have been lost. This is normal and often happens when you install OTA updates.

Anyway, good news is you can root N910PVPU2BOE1 update with the CF Auto Root by Chainfire. Although, the CFAR hasn’t updated yet particularly for the OE1 update but users are reporting it to be already compatible with the latest firmware.
