My Note 4 is rooted and still on Android 5.0.1 (BOE1). What do I have to do to update it to Android 5.1.1?

How do I root it again after updating to 5.1.1?

Thanks for the clarification.

I managed to flash my N4 successfully with N910CXXU2COJ5.

I just want root but keep the functionality as original Samsung so that in future I can re-flash new samsung firmwares as they are updated. Which kernel or rom should I use to flash my N4 the second time?

What kernel or rom most suitable for rooting Android 5.1.1 with N910CXXU2COJ5 firmware?

My N4 suddenly reboot continuously 10-15 times this morning even though I pulled out the battery. It only came back to normal after I off the phone for an hour.

Anyone experienced this and know the problem? Could this be a problem of software app cos I noticed it happened after auto update of apps.
