If you’ve been to XDA Forums at least once, you must have seen some great custom work going on there. Well, most of the work that comes from there only works on a rooted device. If you aren’t rooted, you can’t enjoy those really useful apps or tools on your device.
Fortunately, we have some talented developers like Chainfire who knows to root almost any Android device. If you have got a Samsung Galaxy A7, rooting it is taking a walk in the park. Once rooted, you already know what you can do!
Files You Need
1. Ensure that you have the Samsung USB Drivers installed on your computer. If you haven’t, download and install them first from here.
2. Download Odin to your computer. It’s a nice little tool that helps you flash Samsung phones.
3. Download the CF-Root file to your computer. There’re different files for different models. Therefore, first check your model number from Menu->Settings->About phone and then download the appropriate file from the following list:
Rooting the Samsung Galaxy A7
1. First off, right-click on both CF-Root and Odin and select Extract here. Wait for the files to be extracted to your computer.
2. When the files are done extracting, double-click on Odin and let it launch.
3. Once the Odin launches, click on PDA and navigate to the directory where you have saved CF-Root and select it.
4. Ensure that Repartition is unchecked in the Odin. Leaving it checked-on will cause issues on your device.
5. Auto Reboot and F. Reset Time options should be checkmarked in the Odin.
6. Power down your device.
7. Power up your device by holding down Volume DOWN+Home+Power buttons at the same time.
8. A warning should appear on your screen. Hit Volume UP and you’ll be taken to download mode.
9. Connect your phone to your computer using a USB cable.
10. Hit Start in the Odin and wait for it to flash CF-Root on your device.
11. Once the Odin’s done flashing file, your phone should reboot.
12. You’re all set!
The root files have been injected to your device and you’re now rooted. If you wish to confirm it, get the Root Checker app to verify it for you.
