These are the steps to root Samsung Galaxy A5 SM-A500G smartphones using the CF-Auto-Root tool by Chainfire — the same guy who makes the Triangle Away app — and the Odin flashing tool by Samsung.

REQUIREMENTS

• Users should follow this guide with the SM-A500G variant of the Samsung Galaxy A5 smartphone and not any of the other model numbers in the Samsung Galaxy A5 range. You can found out what your model number is by tapping on the Menu > Settings > About Device > Model Number.
• The CF-Auto-Root tool in the post is based on LRX22G.A500GXXU1BOJ2 firmware and the Android 5.0.2 Lollipop software update. It doesn’t mean you should be running that same firmware but rather it is to be used as an indicator. Older versions of images do not boot on some Samsung smartphones.

BEFORE WE BEGIN

• Download the Samsung USB Drivers for the Sammy A5 smartphone and install them on the Windows computer before you get stuck into the guide.
• Unlock the Developer Options menu on your Galaxy A5 smartphone by tapping on the Menu > Settings > About Device > Build Number and keep tapping until it says you are using the device as a developer.
• Enable the USB Debugging Mode from the Developer Options menu that is now available from your Settings by tapping on the Menu > Settings > Developer Options > USB Debugging Mode.
