ROOT REQUIRED, we aren't responsible for anything you do with this.
You NEED a MicroSD, and it WILL be formatted during this process.

YOU MUST DISABLE REACTIVATION LOCK OR YOU WILL HAVE ISSUES!!!!!!!!!
You can download the eMMC brick bug check app on the Play Store to verify your CID starts with 15. If it does, you are good. If not, it will not work.

UPDATE: Anyone having issues with the "this is for samsung devices only error, please the fix attached to this post


The code below is NOT a script, you must enter the commands manually.

Code:
adb push samsung_unlock_n4-fix /data/local/tmp/
adb shell
su
cd /data/local/tmp/
chmod 777 samsung_unlock_n4-fix
chown root.root samsung_unlock_n4-fix
./samsung_unlock_n4-fix

Allow device to reboot. After full reboot, power down and pull battery. May need to run it twice if it doesn't work after the battery pull.
