The Samsung Galaxy J5 is a step down from the top of the range in the J series. You can tweak your hardware so that your CPU is clocked in a way that it can rival the top end device. Playing with the CPU should only be done by advanced Android users because you can easily clock it too much and fry the hardware. That’s not fair to you or the next person who buys your smartphone from eBay once you decide to sell it.

There are many applications out there that can help you overclock your Android operating system on the Samsung Galaxy J5 smartphone. Some of our favorites that we would suggest checking out include the No Frill CPU Control app, Android Overclock, CPU Control, CPU Clock / Hotplug, and the Kernel Tweaker (required root).

The most popular of the bunch of probably the No Frills version which is ironic considering we usually shy away from anything no frills. No frills usually refer to something that is of a lesser quality.

The firmware build number that the rooting method in this guide is based on is the LMY48B.J500YXXU1AOI2 firmware. It does not mean you need to be running that same firmware on your smartphone according to the rooting tool developer, Chainfire. He gives us that information so we can use it as an indicator only.

Files You Need

  • Download the new CF-Auto-Root file for the SM-J500Y smartphone running Android 5.1.1 from here. Also, download the Samsung USB Drivers from here.
  • You must have a Windows computer to use this guide. The CF-Auto-Root can only be flashed by using the Odin flashing application, and the Odin app is only available for Windows.
  • You are about to void the Samsung warranty when you choose to root the Galaxy J5 smartphone. You can get the warranty working again, but you’ll need to unroot by flashing the stock ROM. You can download the stock ROMs free — usually from the Sam Mobile website — but the download speed is purposefully extremely slow. The reason they do that is to entice you into paying a subscription fee for the faster download. That’s a little heads up for what you are in for when you want to flash the stock ROM to get the warranty working again.

Try flashing the file again and booting to recovery mode manually by using the hardware key combination and it should mean your device is now rooted.

Moreover, anyone with the Samsung Galaxy J5 smartphone which is still not finding it rooted can try installing one of the other versions of the Odin flashing application and seeing if that fixes the problem. There are reports of some versions of the Odin app working for some devices while it won’t work for others. Try a few versions of Odin and one will eventually work.
