How to Unlock Samsung Galaxy J2 Prime (SM-G532G) Using Z3X Box

Cable Unlock, Samsung

Do you want to unlock your phone using the Z3X Box but don’t know where to start? Well, here’s a complete guide that will help you do all the things you need to do to unlock your phone using this method successfully!

WARNING: WE WILL BE ROOTING THE PHONE AND THIS VOIDS THE WARRANTY IF YOU STILL HAVE ONE. THIS ALSO DISABLES KNOX AND ITS FEATURES. YOU WON’T BE ABLE TO USE THEM ANYMORE (LIKE SECURE FOLDER) EVEN IF THE FIRMWARE HAS BEEN RESTORED.

TLDR; below is a YouTube video that supplements this guide but all the downloadable materials are in this written guide.

Note: This guide already assumes that you have already installed Z3X Shell, activated the box, and have installed Samsung Tool Pro.

If you don’t already have a Z3X box and you want to unlock your phone, UnlockBase has a white glove unlock program where one of our technicians unlocks your phone remotely over the internet (for a fee). Through this guide you will; (1) know what files needed to be downloaded, (2) know how to root your Samsung phone safely, and (3) unlock your phone through the Samsung Tool Pro software for the Z3X.

Without further ado, let’s get started!

Files that to be downloaded:

Samsung Android USB Driver – This will allow the phone to communicate with the computer.

TWRP 3.2.3-1 – This will allow us to flash Magisk so we can root the phone.

Magisk Manager – This software that does the actual rooting.
