How to Root XXU1AOA4 Android 4.4.4 on Galaxy A3 A300H

We have put together a detailed step-by-step instructions guide for how to root XXU1AOA4 Android 4.4.4 on Galaxy A3 A300H. If you are used to installing official updates through ODIN on Samsung Galaxy devices, then this should not be any different for you.
Please read every line carefully and make sure you read the tutorial once before actually performing it on your Android device.
To Remember:
  • This root method tutorial is only for Galaxy A3 SM-A300H. Please do not try on any other Galaxy A3 LTE variants.
  • Make sure you backup all your data in your phone before proceeding as a precaution.
  • Your Galaxy A3 should be on an official firmware by Samsung, not a custom ROM.
  • Your phone should be on XXU1AOA4 Android 4.4.4 firmware.
Complete Step-By-Step Instructions:
Step 1 – Download CF-Auto-Root Android 4.4.4 Package for Samsung Galaxy A3 LTE to your computer and extract the zip file.
Step 2 – Download ODIN v3.09 which will help you to root Android 4.4.4 on Samsung Samsung Galaxy A3 LTE A300H.
Step 3 – Switch OFF your phone. Now press and hold the Volume Down + Home buttons together, and then press the Power button till you see a warning screen (as shown below). Press Volume Up to confirm and proceed to the Download Mode.


Step 4 – Make sure you have your Samsung Galaxy A3 LTE USB drivers installed on your computer.
Step 5 – Open ODIN on your computer. Connect your phone to your computer while your phone is in the Download Mode.
Step 6 – If your phone is connected successfully, one of the ID:COM boxes will turn yellow with the COM port number. This step might take some time.
Step 7 – Now select the file that you have to flash/install on your phone. This file will be found from the extracted file in Step 1.
  • Click on ‘PDA’ / ‘AP’ and select the file ‘CF-Auto-Root-a3lte-a3ltexx-smA300H.tar.md5‘.
Step 8 – In ODIN, check the Auto Reboot and F. Reset Time options, if not already.
Step 9 – Now click on the Start button in ODIN. Installation process will start and would take a few minutes to complete.
Step 10 – After the installation is completed, your phone will reboot into Recovery Mode automatically and install the root package / files. Your ID:COM box will also turn green.
Step 11 – After you see the home screen, unplug your phone from the computer.
NOTE: Sometimes the device does NOT boot into Recovery Mode automatically (as given in Step 10) and root your device. If that happens, do the entire procedure again.
OPTIONAL: Still not rooted? Once again perform the entire tutorial, but make sure in ODIN, the “Auto Reboot” option is NOT checked. Then after installation (Step 10), do the following:
Step 11 – Pull out the battery to turn OFF the phone forcefully.
Step 12 – Now boot (turn ON your phone) with Volume Up + Home + Power buttons to go directly into Recovery Mode manually. This will start the install process of rooting your phone.
That’s it! Your Samsung Galaxy A3 has now been rooted on Android 4.4.4 official software update. Check for the SuperSU app in your apps list to verify.
To make sure you have correctly installed the above root method and it’s working, verify with Root Checker as given in the link.
