Android 6.0.1 Marshmallow gives plenty of reasons as to why people might want to install a custom ROM on a smartphone that isn’t able to run that update yet any other way. There is a whole other side to customizing a mobile device that has nothing to do with swapping over the ROM and everything to do with making changes the ROM that is running on your device right now. The way we do that is with root access.

Having root access on Android is another way of saying having control over the root user account. The root user is the person who gets to decide what is installed and uninstalled and there is nothing in your way to stop that from happening anymore.

REQUIREMENTS

• You need to have the Samsung Galaxy J5 smartphone that comes with the SM-J500F model number to use this guide. The CF-Auto-Root tool package in this guide is only made for that one model number and flashing it on another model number likely means that device is bricked until it gets another stock ROM flashed on it.
• You need to have a computer that is running on a version of the Windows operating system to use this guide. The Odin flashing tool is great, but it only works if you are running in a Windows environment.

BEFORE WE BEGIN

• Chainfire had the MMB29M.J500FXXU1BPG5 firmware running on the Samsung Galaxy J5 SM-J500F smartphone when the CF-Auto-Root tool in this guide was developed, but it doesn’t suggest you need to be running on the same. You just need to make sure that you have the right model number and that it is running on the Android 6.0.1 Marshmallow software updates and the rest should be fine.
• Have the Developer Options menu unlocked and the USB Debugging Mode turned on so that you are then able to make the required changes to the Android operating system.
• Ensure that you have installed the Samsung USB Drivers on the computer before getting started on the guide so that the flashing app can detect your Samsung Galaxy J5 smartphone on the computer.
