These are the guidelines to root Samsung Galaxy J7 SM-J7008 smartphones running the current Android 5.1 Lollipop. Once you give your device access to the root file system, you can start installing many more applications from the Google Play Store.
- You must have installed a custom recovery on the Samsung Galaxy J7 smartphone  before you can follow this guide and give it root access.
- The following guide is made for the Samsung Galaxy J7 SM-J7008 model number. You can check that model number by pointing to the Menu > Settings > About Device and taking a look at what the display says for your device.
BEFORE WE BEGIN
- Download the Samsung Galaxy USB Drivers from the Samsung website found on our USB drivers page , or by downloading them from the third-party trusted link we have available on the same page. They both result in the same file on your computer.
- Enable the USB Debugging Mode on the device by heading to the Menu > Settings > Developer Options > USB Debugging Mode. Just check the box for that and it will remember your preferences.
- In case you cannot see any Developer Options menu, you can head over to the About Device menu and tap over the build number. Continue tapping over that number for about 7 or 8 times and it will eventually let you know the device is now unlocked and you are a developer. That means you can go back to the settings and find the Developer Options menu with some additional settings inside. One of those settings is the USB Debugging Mode.
- Those wanting to err on the side of caution can back up the data before starting the guide. The data we are talking about is the pictures, music files, videos, settings, call logs, SMS texts and any other data you do not want to lose. The guide doesn’t wipe data automatically, but you might want to wipe the data if you brick the device.
