The Samsung J1 is a neat smartphone taken from the J series. The J100H variant is easily rooted with the iRoot tool and Odin. We’ll give you two reliable links for both tools and an easy step-by-step guide to follow after the drop.
- Turn on the Samsung smartphone and navigate to the About Device menu. Now check the model number on the display matches up with J100H, otherwise this guide is not for you.
BEFORE WE BEGIN
- Download the Samsung USB Drivers  for mobile phones. Download it directly to the Windows computer you are using in conjunction with this guide.
- You are voiding the warranty of the J1 by continuing from here. Many Samsung devices come with added security which means an unroot guide doesn’t always get the warranty back. You’ll need to look into the J1 specifically if the warranty concerns you.
HOW TO ROOT THE SAMSUNG J1 SM-J100H
- Download and extract the root file from here  on the desktop of the Windows computer.
- Download Odin here  to the computer and extract the file. Run the Odin program and leave it open.
- Completely switch off the device and boot it back up in Download Mode.
- Hold the buttons to get in Download Mode . You should see a yellow warning symbol with other yellow text on the display. Press Volume Up at this time.
