[Verizon Galaxy Note 4 General] chriskader:
This guide will walk you through the process of converting your Retail Note 4 to a Developer Edition Note 4. This means you have an unlocked boot loader and you are free to do what you wish with your device.

Requirements:

Retail Note 4 (Verizon)

Computer (PC, Linux or Window)

USB Cable

Samsung USB Drivers (If you are on Windows)

SD Card (Recommend a small one that you do not mind storing away for later)

ADB (Android Debug Bridge)

Root (Either Temp or Perm, that will not be explained here)

Samsung Unlock file (Creators Thread)

Steps:

- Verify you have an ADB connection to your device and you have root.

Connect your phone and launch ADB in either command prompt or terminal (Depending on your OS).

Type the following command to view the currently connected devices:

adb devices

You should see a list of devices. If not, verify USB Debug Mode is enabled on your phone.

-Copying the unlock file to your phone

After you have downloaded the file from ryanbg's thread (samsung_unlock_n4-2) we need to copy it to the device. You will want to make sure your current directory is the directory that the file you downloaded is in.

Time to push the file to the phone, run the below command:

adb push samsung_unlock_n4-2 /data/local/tmp/

-Connect to your phone

Type the following command:

adb shell

You are now in in a shell through ADB on your phone.

Elevate your permissions by entering:

su

You may get a confirmation on your phone for requesting root access. Be sure to grant ADB permission.

-Change Directory

Go to the directory we copied our files to

cd /data/local/tmp/

-CHMOD and CHOWN the unlock file

This allows us to actually execute the file. Execute the below commands

chmod 777 samsung_unlock_n4-2

chown root.root samsung_unlock_n4-2

-Time to execute

Running the below command will generate a warning and a requirement to enter yes or no. Read the warning carefully before continuing:

./samsung_unlock_n4-2

At this point you will see a few thing similar to this:

[+] CID at boot time is/was: 1501xxxxxxxxxxxxxxxxxxxxxxxxx
[+] device not yet dev CID, now changing to dev CID
[+] programming new CID 150100523231384d4100657e54fc1200
[+] success! powering off device, power back on and verify CID
[+] then run this binary again to finish the process

As binary states, your phone CID is changing is going to reboot.

Before turning your phone back on, be sure the SD card you are okay with formatting is inserted into the phone.

Once your phone comes back online, launch terminal, ADB shell, obtain root access, and change directories. Now launch the unlock binary again:

./samsung_unlock_n4-2

You will see the same warning and you will need to enter yes or no again. Once you enter yes, you should see something like this.

[+] CID at boot time is/was: 150100523231384d4100657e54fc1200
[+] dev CID matching, proceding to unlock
[+] backing up loaders, this will take a few minutes
[+] loaders successfully backed up
[+] success! powering off device, hopefully its not bricked!

Keep the SD card in a safe place. If for some reason you ever break your phone, you can possibly use the loaders on this card to fix it.

Power your phone up in download mode (VOL-DOWN + HOME + POWER). Your phone should now show Developer mode. If this is not the case, you either did something wrong or your phone is not a Verizon Note 4 :)
