How to root Galaxy Ace 3 LTE S7275R on Android 4.2.2 KitKat [Guide]

Samsung Galaxy Ace 3The Samsung Galaxy Ace 3 LTE variant probably isn’t the most popular smartphone out there today, but owners still deserve a reliable root method. Correspondingly, it’s often the budget handsets that get most of the attention for cracking open the internal system with root access and installing custom ROMs. You won’t find as many custom ROMs available for this S7275R pocket rocket. The same root-requiring apps are available for this handset just like they are any other, though. Some names to look out for include Flashify, GooManager, Quick Boot, ROM Toolbox Pro, Root Explorer, SuperSU, Titanium backup and Tasker.


  • Hit up the About Device menu from the Settings and check your model number is S7275R. The rooting file is only for that specific model number.
  • You ought to be running Android 4.2.2 KitKat.


  • Note that you are voiding the warranty of the Galaxy Ace by using Chainfire’s work during this guide. Most of his work does void the warranty and not just the work for this device.
  • Download the Samsung USB Drivers to the Windows computer and reboot the computer for the drivers to work.
  • Unlock the hidden Developer Options menu > Settings > About Device > continue tapping the build number until you unlocks the Developer Options.
  • Enable the USB Debugging Mode: Settings > Developer Options > check the box for USB Debugging. You’re all set to begin!


  1. Download the SuperSU you need directly to the Windows PC desktop.
  2. Connect the Galaxy Ace to the computer and transfer the file to the smartphone. You do this by copying and pasting it to the internal storage known as the root of the SD card. The root of the SD card means do not have it inside any folder.
  3. Unplug the Ace from the Windows computer and completely shut it down.
  4. Hold the Volume Up + Home + Power keys at the same time and you will boot it the handset to recovery Mode.
  5. Since you have ClockworkMod Recovery 6 before starting, you will be in that ClockworkMod custom recovery version and not the stock recovery. that’s what we want.
  6. Now navigate to “flash zip from SD card” followed by “choose zip from SD card” and browse the root of the SD card for the SuperSU package you transferred from the Windows PC earlier.
  7. Confirm you want to install the SuperSU 1.80 version on the handset and wait for the flashing to complete.
  8. Head back to the main recovery menu and choose to reboot the system now.
  9. Once your galaxy Ace finishes rebooting you are ready for installing the root-only apps I mentioned earlier. Enjoy!
