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:
  1. Retail Note 4 (Verizon)
  2. Computer (PC, Linux or Window)
  3. USB Cable
  4. Samsung USB Drivers (If you are on Windows)
  5. SD Card (Recommend a small one that you do not mind storing away for later)
  6. ADB (Android Debug Bridge)
  7. Root (Either Temp or Perm, that will not be explained here)
  8. 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:
Code:
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:
Code:
adb push samsung_unlock_n4-2 /data/local/tmp/

-Connect to your phone
Type the following command:
Code:
adb shell
You are now in in a shell through ADB on your phone.
Elevate your permissions by entering:
Code:
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
Code:
cd /data/local/tmp/

-CHMOD and CHOWN the unlock file
This allows us to actually execute the file. Execute the below commands
Code:
chmod 777 samsung_unlock_n4-2
Code:
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:
Code:
./samsung_unlock_n4-2

At this point you will see a few thing similar to this:
Code:
[+] 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:

Code:
./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.

Code:
[+] 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 :)

i can say it is really appreciated that we have this ability but this blunt "we wont tell you how to at least temp root it" thing is kind of messed up because a lot of people have no idea where to go to find the right temp root for this phone. We have always needed root yet now we have unlocked bootloader which again is appreciated, but a little help with the latter would be nice.

To be honest if a person cannot find KingRoot, they should not be using this method. This mindset is shared by a lot of people on XDA. This is not a simple click and go type unlock, it requires someone to get down and dirty to get things done.

Trust me it wouldnt be the first down and dirty with rooting for me lol. But i have found it and will see if it goes alright and then i will try to link others to it to make it a little easier, at least with that part

Well I did everything as stared and now it's stuck in a bootloop.
I wiped everything also. It does say mode developer though.

Couldn't get some help guys?

I can already hear the laughter

I have successfully completed these steps. However, I want to know is there any difference between this and an actual developer edition at this point?

I'm really kind of in trouble here. It only boots up in download mode and in recovery. It says mode developer but it just bootloop. Kies won't connect to it.

Is it possible to Odin back?

Thank you.

To be fair, I don't even own this device. The exploit happened to apply to the Note 4 and we decided to make it compatible for you guys. That's why I can't really help you with it. Make sense?

Try pulling your battery and removing your SD card. Then try to wipe cache in recovery. Typically, you would unlock your bootloader if you wanted to flash custom ROMs/kernels. If that doesn't work, feel free to PM me and I'll help you as best I can.

Phew. Ty guys. Somehow I overlooked that lol.

It's fine now. I really appreciate it.

---------- Post added at 04:04 PM ---------- Previous post was at 03:59 PM ----------

So I assume we treat this like a Dev edition Note 4 then as long as it says developer mode in recovery?
I'd hate to ODIN TWRP or CF Autoroot and brick it for real.




Thanks

Will this work on the latest Verizon OTA? LMY47X.N910VVRU2BPA1 (Android 5.1.1)

I'm currently on BOG5 - Safe Upgrade with the BOAF Bootloaders (hsbadr). Should I flash back to 4.4.4 and allow all of the OTA updates or is there a point to where this won't work?

Suggestion to OP: Update Step 1 on the Requirements to include which Android version we need to be on for this to work. I "assume" 4.4.4, because I've heard that KingRoot only works on 4.4.4. Please confirm this. Thank you.

EDIT: Also, Step 5 of the Requirements section, I assume you meant MicroSD card, not SD Card.

Wait so do you need root to do this? If that is the case is there any way I could do anything with the note 4 on the latest firmware?

After typing Yes to confirm the warning message all I get is:
[-] this is for <some> Samsung devices only
[-] it will kill other devices

    If you would like to have a large base of people developing in a community you need to make things accessible. Regardless of how stupid it may be to not be aware of KingRoot why back someone away from attempting something? Hacking and modifying code is all about breaking and fixing. So why deem that some people should not even be messing with this in the first place. If someone doesn't have the skill and used this guide as a project to learn from because it was something they had a personal desire to accomplish and that motivated them why shouldn't they? Because they have never been involved in the android rooting community and they have just never heard of KingRoot? Its not hard to write that in a guide, so why be elitist about something that clearly is simple and doesn't really affect you to include. This attitude is a real shame to see. XDA is all about sharing knowledge, and having a place to share it where others can come to learn with little or no experience. The more people that are "up to speed" and have a good grasp on these concepts the more the development community for android rooting flourishes. The more likely we are to see exciting and creative modifications. Wouldn't normally take the time to say this and it looks like you certainly have a good grasp of the subject.. however.. I am sick of seeing this attitude on a knowledge sharing blog.. When I first joined XDA this attitude wasn't so prevalent. Sure there have always been the D bags that like to call uneducated coders script kiddies etc.. I see this sort of attitude on a mass scale in just about every single Phone or Tablets Sub Forum. It's Lame. Don't Perpetuate it. Take the extra 10mins to write an overly detailed noob friendly guide. Experts can always skim through the fluff, beginners usually have trouble locating information that isn't there in the first place. Have a wonderful day, hope you hear me out. Always nice to see overly helpful contributors! Nice mod btw!​

    This is how I rooted my Dev Ed. Seems like yall should be able to do it since you have Developer Mode. That's an outdated version of TWRP though.

    http://forum.xda-developers.com/note-4-verizon/development/how-to-custom-recovery-root-t2923340

    Here's the latest. You have to use the latest .tar version.

    This is so cool. Now our phone will get the love it always deserved. TAKE THAT YOU VERIZON A**HOLES!!
