Everyone who roots the Samsung Galaxy A3 smartphone can install the applications that say “root required” from the Google Play Store. One of those applications is the Titanium Backup application. With Titanium, installers can have a better backup solution than any third-party app that doesn’t require root access. Further, the Titanium backup app comes with additional features, such as the ability to remove stock apps from the carrier and manufacture. Often those stock applications are referred to as bloatware on a device due to the fact that they take away the performance of your device and are of little use — especially if you literally do not use them.
Samsung is a cool brand of smartphone to own for several reasons. The main reason is you can root most devices by using the CF-Auto-Root tool by Chainfire. The next best reason is Samsung doesn’t seem to mind people rooting and you can use the rooting app without the need of unlocking the bootloader at all.
Files You Need
- The CF-Auto-Root tool in this guide is based on the LRX22G.A300FUXXU1BOJ5 firmware which is part of an Android 5.0.2 Lollipop update for some regions. It doesn’t mean you need to be running that same firmware build on your Samsung Galaxy A3 device. You should use the build ID as an indicator because some of the Samsung devices won’t boot old images.
- Download the CF-Auto-Root tool for the SM-A300FU running Android 5.0.2 from this page.
Rooting the Samsung Galaxy A3 SM-A300FU On Android 5.0.2
- Download the CF-Auto-Root tool for the Galaxy A3 SM-A300FU on Android 5.0.2 from the link above and extract the file on the desktop.
- You should see the Odin down loader and the CF-Auto-Root tar.md5 for the A3 on the desktop.
- Double-click the Odin downloader and the flashing tool user-interface will open on the desktop.
- Enable the USB Debugging Mode on the Samsung Galaxy A3 device so you can connect to the computer and use the Odin flashing tool.
- Do not make any changes to the default settings you can see from the Odin flashing tool user-interface.
- Boot the Samsung Galaxy A3 smartphone in download mode and connect it to the computer.
- After a few moments, you need to see the ID: COM port light up a green color from the Odin user-interface. If your device is not detected by Odin, it means the USB Drivers are not working properly. You can install the universal ADB Driver to fix that. It may require you closing and opening the Odin application again, or even rebooting the computer before the drivers start working after you install them.
- Click the AP button from the Odin application on the PC and browse the desktop for the A3’s CF-Auto-Root tar.md5 file.
- Click the Start button when you are ready for the Odin application to flash the device to your device.
- Wait until Odin gives you the pass message and the Samsung Galaxy A3’s display says the device is restoring the stock recovery, cleaning up and then about to reboot in 10 seconds.
- The Samsung Galaxy A3 device will now reboot to recovery mode automatically because the Auto Reboot box is checked. Any device that does not reboot to recovery mode will not be rooted. You will need the Samsung Galaxy A3 smartphone to reach recovery mode using the hardware buttons during the first time boot if that happens.
Anyone who has the universal ADB Driver working and the device added but cannot get the guide to work should try installing a different version of the Odin flashing tool. Sometimes one version will work and another will not.
