Galaxy J3 belongs to Samsung’s mid-range Galaxy J series. The J3 2017 was launched last year in July. Galaxy J3 is equipped with a 5.0-inch 720P display. Samsung’s in-house Exynos 7570 CPU is powering up this phone. There is Mali-T720 MP2 GPU to accompany the Exynos CPU on this phone. The Galaxy J3 has a 16GB internal storage and 2GB RAM. There is a microSD card slot which supports up to 256GB of external storage. A 13MP camera is added at the back while a 5MP camera is available on the front.

Galaxy J3 2017 ran on Android 7.0 Nougat out of the box. There are likely chances that this phone will not get any further update of Android and it will stick to Android Nougat only. It has a 2,400 mAh battery under the hood. Galaxy J3 is a good choice for those who are looking for a mid-range phone inclined towards a budget-friendly lineup.

Install TWRP Recovery on Galaxy J3 2017

  1. Open Odin3.exe file from the extracted Odin files that you downloaded above.
  2. Put your Galaxy J3 2017 in download mode now. To do so, turn off your phone first. Now turn it on by pressing and holding Volume Down + Power + Home button. As soon as your device boots up showing a Downloading screen, leave the keys.
  3. Connect your phone to your PC now. Odin should show an “Added” message in the logs and also show the blue light in the ID:COM box. This will verify a successful connection between your phone and your PC.
  4. Now click on the “AP” tab in Odin and select the TWRP Recovery.img.tar file according to your device carefully.
  5. The options ticked in Odin should be only “F.Reset Time“. Make sure that the Auto-Reboot option is not checked, we do not want to reboot the phone after flashing TWRP recovery.
  6. After selecting the file and checking/unchecking the options carefully, hit the start button. Odin will now flash the TWRP and show you a PASS message in a few minutes.
  7. Once done, disconnect your device from your PC now. Do not reboot your device.

Root and disable forced encryption

  1. Now you need to boot directly into TWRP Recovery. Turn off your phone completely and turn it on by pressing and holding Volume Up + Home + Power key now. Your phone should successfully boot into newly installed custom recovery.
  2. TWRP will ask you whether you want to allow modifications or not, you will need to swipe the finger to the right to enable modifications. Swiping the finger to right will trigger dm-verity, if you will need to disable it immediately. Leaving it enabled will let you boot the phone neither root it. This is an important stuff since we want to be able to modify the system.
  3. Now tap “Wipe > Format Data > type “yes” to format data. This is important to disable encryption. This step will factory reset your phone, so make sure that you’ve backed up the entire data at hand.
  4. Now make sure that you’ve copied the SuperSU.zip and dm-verity.zip files in external SD Card or USB OTG, if not then transfer both these files to your external SD Card by using MTP mode in TWRP now.
  5. Once you have the files, tap “Install > locate the SuperSU.zip according to the location where you copied > flash it”.
  6. Now once again tap “Install > locate the dm-verity.zip file > flash it”.
  7. Once done flashing, reboot your phone to the system.
  8. That’s all. You’re rooted and have a TWRP recovery installed. Best of luck.
