Oh, yeah that's a 5.1 bootloader. There's no way that I'm aware of to update to MM without going through the process again, which will completely wipe the internal storage (I always like to mention this part because I kept forgetting myself and would lose a bunch of stuff).

This post has some pretty good instructions to go from BPA1 to CPD1.

You're welcome.



Sure. Why is it posted then?!



No, it's already tested a few days ago. I just recreated the tar to include MM modem and NON-HLOS so that you don't have to flash extra tars. I'll upload it very soon, but in the meanwhile, you can familiarize yourself with the process and do any preliminary steps (backups, LP unlock, ... etc)

Many rom links in XDA return 404 unfortunately. Only good source of custom roms are in androidfilehost.com. You can search for n910v or trlte to get list of available roms. And you can find N910VVRU2CQL1_PartialFirmware_DevEd.zip on androidfilehost.

    You NEED a MicroSD, and it WILL be formatted during this process.​

    THIS WILL NOT WORK ON GALAXY S3/GALAXY S4/GALAXY S6|e/Galaxy S7|e. It will NOT work on AT&T.

    We can't help you root or teach you how to use ADB. It's important you have the ability to do these things or research them a bit before blindly using this.    ​

    This is a summarized guide with the required files to upgrade and unlock the new bootlloader required for Android 6.0.1 Marshmallow (N910VVRU2CPD1) on Verizon Samsung Galaxy Note 4 (SM-N910V). Extended details about each step (e.g., rooting) can be found in the General Section of this forum.


    If you're already on unlocked Android 6.0.1 Marshmallow bootloader, you can extract and flash the DevEd partial firmware via Odin to upgrade:

    This will upgrade the base firmware (NON-HLOS, modem, rpm, sbl1, sdi, and tz) to N910VVRU2CQL1.
    Click to expand...
    Click to collapse


    Requirements:
    • Verizon Samung Galaxy Note 4 (SM-N910V)
    • All files in the Download Section
    • Odin installed on Windows
    • ADB installed on Windows, Mac, or Linux
    Click to expand...
    Click to collapse


    Notes:
    • If you own a Developer Edition, you can still use this method unless you want to keep your original CID and signature. If so, make backup of your aboot and CID! You may contact @ryanbg to create a special unlock binary for your own device.
    • Everyone should unlock his bootloader on Lollipop to save extra steps and prevent complications. The official thread (or any guides based on it) will change your device CID to 150100523231384d4100657e54fc1200 which will match and allow for direct unlocking of the Marshmallow bootloader. Otherwise, the unlock binary will change your decvice CID and reboot, which may end up with a bootloop that requires extra step(s) to fix.
    • It's recommended to wipe data (factory reset) in stock recovery after Odin flash of full firmware.
    • Make appropriate backups of everything before trying this.

    Instructions:
    • Unlock your Lollipop bootloader to match CID (start here)
      You can ignore this step if you did it already. If not and for Developer Edition owners, I'd recommend to flash N910VVRU2BPA1 Full Firmware via Odin before unlocking.
    • Boot into Download Mode
    • Extract and flash N910VVRU2BPA1_N910VVRU2CPD1_FullFirmware.tar.md5 via Odin
      This will make you on Lollipop with Marshmallow bootchain/firmware/modem, which is rootable.
    • Root your device (Check General Section for detailed instructions)
      Note that WiFi will not work due to the updated bootloader, but you can use Mobile data if needed for rooting.
    • Unlock the bootloader using the same method:
      Code: 
      [email protected]:/ # cd /data/local/tmp/
[email protected]:/ # chmod 777 samsung_unlock_n4-fix                                                <
[email protected]:/ # ./samsung_unlock_n4-fix

    This is the steps I took to complete this. I am not a dev and I don't take any credit. All the credit is to @hsbadr


    Once your unlocked and rooted on 5.1.1
    Flash the new bootloader that was posted in the download section of the OP.(I kept the reboot box checked in Odin)
    When you phone powers back on, download kingroot and rootchecker (Just like you did when you unlocked your bootloader on 5.1.1)
    Enable developer mode and USB debugging in settings
    In Windows, Copy samsung_unlock_n4-fix to the "Minimal ADB and Fastboot" install folder location. (Make sure you delete the old samsung_unlock_n4_fix from the last time you did this process)
    Plug in with USB cable and make sure Usb settings are MTP and check ok on USB Debugging
    Root with kingroot and check root with Rootchecker
    open Command window in your ADB folder and type
    (1) adb devices
    (2) adb push samsung_unlock_n4-fix /data/local/tmp/ (make sure the samsung_unlock_n4-fix is typed in exactly as it is in the adb folder)
    (3) adb shell
    (4) su ( You have to grant root permission on the phone and continue)
    (5) cd /data/local/tmp/
    (6) chmod 777 samsung_unlock_n4-fix
    (7) ./samsung_unlock_n4-fix

    Boot into Download Mode
    Extract and flash twrp-3.0.2-0-trltevzw.tar.md5 via Odin
    Boot into TWRP recovery
    Flash JasmineROM v6.0 or any Marshmallow-based ROM
    Reboot to system
    ENJOY!
