The InstaWiFi app is probably one of the coolest apps you can install on your Samsung Galaxy A3 device once you have access to the root file system. The access to the root file system is what we can root access for short. The InstaWiFi app lets users connect and share WiFi networks with an NFC tag. You can also choose to connect via a QR code if that’s your thing.

Rooting the Samsung Galaxy A3 SM-A3009

  1. Download the rooting package for the A3009 device from the files section above. It ends up in the Downloads folder by default on a Windows operating system. Open that Downloads folder and click and drag the A3 rooting file over to the desktop.
  2. Right-click over the file and select the “extract here” option from the menu.
  3. Double-click the mouse over to the Odin executable and the Odin user-interface will open on your desktop.
  4. Turn off the Samsung Galaxy A3 smartphone and reboot it in download mode. The download mode is what we need to start flashing files.
  5. Reboot the A3 holding the Volume Down + Home + Power buttons and then press the Volume Up button when it tells you on the screen.
  6. Connect the Galaxy A3 to the computer using the USB cable.
  7. The ID: COM port from the Odin user-interface lights up a color if your ADB Drivers are working. Try rebooting the computer if you cannot see that.
  8. Click the AP/PDA button from the Odin user-interface and upload the A3 CF-Root package from the desktop that came out of your original extracted rooting file.
  9. Do not adjust any of the Odin default settings you get after opening a fresh copy of the Odin flashing tool.
  10. Click the Start button and wait for the Odin flashing tool to flash that CF-Root exploit on your A3 smartphone.
  11. The Odin user-interface will give you a pass message in a box and the Galaxy A3 should reboot by itself when it’s ready. If your device does not reboot, do that now manually.
  12. Open the Google Play Store app from your A3 device and browse for the root checker app. The app will check if your A3 device is rooted.
  13. Check the app drawer on your A3 device for the SuperSU app. the SuperSU app is normally installed by default with the CF-Root and CF-Auto-Root rooting tool since it is made by the same developer (Chainfire). However, if you do not see SuperSU on your device, you need to open the Google Play Store and search for the SuperSU app by Chainfire and install the same.

The SuperSU application is what keeps your device safe from malware and any vorus that might try to get access to your Samsung Galaxy A3 root file system.
