This method uses a modified version of the official NJ5 OTA to update and "Keep Root." The file is flashed in Safestrap and the end result is a 100% Stock, Rooted, NJ5 Device. However you must be 100% Stock NC2 (except for root and Safestrap) before proceeding.

**You can Odin back to NC2, after taking the NJ5 update, at anytime**

1. Place the N900A_NC2-NJ5-KeepRoot_OTA.zip onto your ext-sdcard.
2. Boot into Safestrap recovery but Do Not Wipe!
3. Flash the N900A_NC2-NJ5-KeepRoot_OTA.zip in the "Stock Slot." Once flashing is complete press "Home" and reboot into "Download" mode.
4. Last, flash the N900A_NJ5_Stock_Kernel in Odin's PDA slot(AP in Odin v3.09+).

Once complete the phone will reboot then "optimize apps" before completely rebooting. Done!

Notes & Known Issues:
1. Neither User Data nor your Knox Warranty Flag will be affected using this method.
2. Should the update fail consider flashing back to factory stock NC2 using the N900AUCUCNC2_Full_Odin_Tar (flash in Odin's slot(AP in Odin v3.09+)), then root, install Safestrap, and continue with the above process.
3. Safestrap will not function after updating to NJ5 4.4.4. See workaround here:

Alternative Custom ROM Method: (If you don't know the difference between each ROM please use the search function!)
N900A_NJ5_100%_Stock_Rooted_ROM.zip
N900A_NJ5_Stock_Deodexed_Rooted_ROM.zip

1. Use Safestrap's "Backup" function to backup your User Data.
2. Place the ROM onto your ext-sdcard.
3. Reboot into Safestrap recovery then perform an "Advanced Wipe" and wipe everything but your ext-sdcard.
4. Flash the ROM using the "Stock Slot."
5. Once complete press "Home" then "Restore" and restore User Data.
6. Next press "Reboot" and reboot into "Download Mode."
7. Flash the N900A_NJ5_Stock_Kernel.tar.md5 in Odin's PDA slot(AP in Odin v3.09+). Done!

Thanks to @carl1961 for sharing his nandroid backups used to create the ROM's!

Notes & Known Issues:
1. This Custom ROM process will update your Modem, Non-hlos, System, Kernel, Stock Recovery, and Bootloader to NJ5.
2. Safestrap will not function after updating to NJ5 4.4.4. See workaround here: http://forum.xda-developers.com/show....php?t=2957471

Now the only thing we missing is how to odin back to the OTA because I'm sure once we update our bootloaders will probably be updated too. And that could be a headache if we want to revert back if we f... up our devices

Already checked that out. You are still able to do a full odin downgrade back to NC2 even after taking the NJ5 ota update.

Correct, flash back to NC2 then follow the OP. In regard to future updates, yes having root may prevent future updates from successfully flashing.

No, flashing a modified ota.zip will not have any adverse effects on future ota's or anything else.
