Users of the Samsung Galaxy S4 LTE with the model number GT-I9505 can now update their devices to the Android 4.4.3 KitKat operating system using a new custom ROM, based on Android Open Source BAM, or AOSB, project.

The custom firmware has been developed using the latest Android 4.4.3 over-the-air update and it brings many new features to the handset, including Android-4.4.3 r1.1 KTU84L, AOSB Power Saver Manager, GPS Optimizer, keyboard animation, scrolling animation, AOKP Custom Navigation Bar, AOSPAL Lockscreen Blur and a navigation bar with custom dimensions.

The AOSB ROM for the Galaxy S4 LTE is not an official release by Samsung, so users need to root their device before flashing the firmware. The device is also required to have custom recovery such as ClockworkMod to flash the ROM zip.

Here are some aspects that users should know before flashing the ROM:

- Ensure proper back-up for personal data on the phone

- The handset should have at least 80 percent battery power

- The computer to be used in the installation process must have USB drivers for the Galaxy S4 installed

- Ensure USB Debugging is enabled on the phone

- The tutorial is only for the Samsung Galaxy S4 LTE (GT-I9505)

Users should also note that if the device freezes on booting, users can perform wipe cache partition and wipe dalvik before rebooting the phone.

Note: International Business Times cannot be held responsible if anything goes wrong. Users should proceed at their own risk.


Step 1: Download the Android 4.4.3 AOSB ROM for the Galaxy S4 LTE on your computer.

Step 2: Download Google Apps on the computer.

Step 3: Connect the Galaxy S4 LTE to the PC via USB cable and copy the ROM to the root folder of the handset’s SD card without extracting them.

Step 4: Disconnect the USB cable and switch off the phone.

Step 5 Get into the Recovery Mode by pressing and holding Volume Up, Home and Power buttons simultaneously.

Step 6: In the ClockworkMod Recovery Mode, perform a factory reset by selecting “wipe data/factory reset.” Use the Power button to select options. Now, perform a cache wipe by selecting “wipe cache partition.”

Step 7: From CWM recovery, go to “Advanced” menu and then select “wipe dalvik cache.”

Step 7: Go back to the main recovery screen and select “install zip from sdcard” and then select “choose zip from sdcard.”

Step 8: Use the Volume keys to go to the Android 4.4.3 ROM zip file copied to the SD card and select it using the Power button.

Step 9: Repeat the previous step for the Google Apps and install it on the phone.

Step 10: After the installation is complete, press the “+++Go Back+++” button to go to the main recovery menu and select “reboot system now.”

After the installation is complete, the Galaxy S4 LTE will reboot automatically. Once the phone is rebooted, it should begin running on the Android 4.4.3 AOSB KitKat custom ROM.
