There are always plenty of reasons to root your Samsung Galaxy J5 smartphone in general. The most favorite reason of all is to install more apps. While applications might make you think of games and another general idea, the root apps come with an enormous amount of power and they can do a great deal more to your device than you might first think.

One example of a great root application that we recommend you check out from the Google Play Store is the Screen Standby app. As the name suggests, using this app will make your screen stays off when it is meant to be turned off. Sometimes our Samsung Galaxy J5 smartphones can “wake up” when we were wanting them sleeping. The Screen Standby app can prevent that from happening. It’s also a big deal that we make that happen so we can save battery life and save the life of your hardware too. That means your short term battery life will be better as well as your long-term battery life should be better. Meaning you can expect your device’s battery to last a longer amount of hours over the lifespan of your device. That’s more important for smartphones that don’t have any option to replace the battery, but it’s important for everybody if you want to save money. Protecting the hardware is even more important because you don’t replace the hardware either. Once that hardware is done, you will likely prefer paying for a new smartphone than attempting to go to the great lengths of trouble to fix it.

Samsung Galaxy J5

The firmware that the rooting method in this guide for the Samsung Galaxy J5 smartphone is based on comes with the LMY47O.J5008ZMU1AOH2 build number. Chainfire gives us that build number to use as an indicator because some of the Samsung devices like potentially the Samsung Galaxy J5 will not boot the older images. It does not, however, mean that you need to be flashing that same firmware build ID on your Samsung Galaxy J5 smartphone before you use this guide

Files You Need

  • Download the new CF-Auto-Root for the SM-J5008 smartphone running the Android 5.1 from here.
  • Download the Samsung USB Drivers for the computer you are using to root the J5 smartphone from here.
  • You must have a Windows computer to use this guide or else the flashing will not work.
  • Samsung firmware updates — otherwise known as just software updates to some — are rolling out for devices all the time. Sometimes the major updates that update a smartphone from builds like Android 5.0 to Android 5.1 can brin new bootloaders with them. A new bootloader will mean the CF-Auto-Root tool needs updating before it will start working again. To get the rooting file working again, people need to submit the new recovery images to the official CF-Auto-Root thread made by Chainfire from the XDA-Developers website. Once Chainfire gets the new recovery image files, he can then update the CF-Auto-Root file that is made for your device, and it will start working again.

Rooting the Samsung Galaxy J5 Duos SM-J5008 running the Android 5.1 Lollipop update

  1. Enable the USB Debugging Mode on the Galaxy J5 before you follow the rest of the guide so the device can be detected by the computer and its apps we are using.
  2. Extract the rooting package to the desktop of the computer and the rooting file and the Odin file should pop out onto the desktop of the computer for you.
  3. Install the Samsung USB Drivers on your Windows computer before you move to the next step.
  4. Double-click the Odin executable file so the flashing tool opens up and you have the user interface waiting for you to connect.
  5. Boot the Samsung Galaxy J5 SM-J5008 smartphone in download mode and then connect it to the computer with the USB cable.
  6. Wait until you can see the yellow or blue ID: COM port from the Odin user interface letting you know that your J5 smartphone is connected.
  7. Click the AP button and then browse the desktop location for the J5’s rooting file that you extract earlier.
  8. Do not change any of the default settings from the Odin user interface on the computer.
  9. Click the Start button.
  10. In a few seconds, check the display of your Samsung Galaxy J5 smartphone for when it says that it is installing the SuperSU package, cleaning up the cache and then flashing the stock recovery again on your device.
  11. Now look back at the display of the computer for the Odin user interface to give you a green pass message inside a box.

In conclusion, that’s all you need to root the Samsung Galaxy J5 SM-J5008 smartphone running the Android 5.1 Lollipop update by using the CF-Auto-Root tool. Your smartphone will now reboot, and it is ready to disconnect from the computer. You should find the SuperSU app is available on the device; head over to the Google Play Store to install the root checker app to make sure everything worked.

Anyone who does not have a rooted smartphone should try a reboot to recovery mode manually after the flashing completes or install a new version of the Odin flashing application.
