Install TWRP & Root Samsung Galaxy J2 Pro 2018
 

When it comes to third-party development, Samsung devices as a whole are a peculiar case. The flagships are quite popular but they often divide the development with a locked down Snapdragon version for the US and some other markets. The Internationally sold Exynos variants are often way ahead in terms of third-party support. Samsung’s more affordable devices don’t really get as much developer love. It’s generally a hit or a miss. If you bought the Samsung J2 Pro 2018, you can at least now root your device and install TWRP on it.

Warning

You probably know already, rooting will void your warranty. To root your device you will be relying on third-party tools and software. None of these third-parties, nor us, will take any blame in case you end up harming your device. You must understand the risks involved and take full responsibility for your actions. You can proceed with confidence that the method does work. Still, things can go wrong. In which case, you must understand that you were warned, and you still went with it anyway. Therefore, DroidViews cannot be held liable for any damage to your device.

Requirements

  • A Samsung Galaxy J2 Pro 2018 with an unlocked bootloader.
  • A Windows computer with ADB and fastboot installed and set up. We do have a dedicated, detailed guide on how to do just that. You can check it out by following the links below.
  • You will also need to install the latest Samsung USB Drivers in order to get things working.
  • Enable USB debugging and OEM Unlock on your Galaxy Note 9. To do this go to your Settings > About phone > Software information. Now tap on the Build number 7 times until you see a toast message “Developer option enabled”. Go back to Settings and you should see Developer Options listed towards the bottom. Tap on it and enable OEM Unlock and USB Debugging. In case you don’t see an OEM Unlock option here, there’s currently no workaround so you will just have to wait until there is.
  • Ensure that your Galaxy J2 Pro has at least 70% battery.
  • The process does require you to format your device so make sure you have backed up everything important, including files and folders on your device’s internal storage.
