How to Update Galaxy S4 GT-I9500 to Official Android 4.2.2 UBUADMK Jelly Bean Firmware

Update Galaxy S4 GT-I9500 to Official Android 4.2.2 UBUAMDK Jelly Bean Firmware [How to Manually Install]
Update Galaxy S4 GT-I9500 to Official Android 4.2.2 UBUAMDK Jelly Bean Firmware

Step 1: Download Android 4.2.2 UBUADMK Jelly Bean official firmware for Galaxy S4 GT-I9500 and Odin v3.07 on your computer.

Step 2: Extract the downloaded firmware zip file to the desktop to obtain a '.tar.md5' file and some other files (optional).

Step 3: Extract Odin zip file to get Odin3 v3.07.exe as well as few other files.

Step 4: Power off the phone and wait for vibration (about 5 to 6 seconds) to confirm complete device shutdown. Now, boot the phone into Download Mode by pressing and holding Volume Down, Home and Power button together. When a "Warning!" message appears on screen, hit Volume Up button to progress into Download Mode.

Step 5: Launch Odin3 v3.07.exe that you obtained in Step 3 as an Administrator, as Admin privileges are required to complete the installation process smoothly.

Step 6: Connect the phone to computer via USB cable. When the phone is connected successfully, Odin's message box says "Added!" in the bottom left of the screen. If the message fails to appear, then try another USB port (preferably the one at the back of your desktop computer). If all else fails, just reinstall the phone's USB drivers on computer. Once the "Added!!" message appears in Odin, you can proceed to the next step. At this point, the ID: COM box will turn yellow with the corresponding COM port number suggesting that the device is added successfully.

Step 7: Choose the following files from I9500UBUAMDK folder that you extracted in Step 2 using respective checkbox options:

  • Select the PDA checkbox, and click the file named '.tar.md5' (required)
  • Choose the Phone checkbox, and select the file named 'modem' (ignore if the file is not found in the extracted folder)
  • Click the CSC checkbox, and choose the file named 'CSC' (ignore if the file is missing)
  • Choose the PIT checkbox, and click the .pit file. (ignore if there is no such file)

Step 8: In Odin, enable Auto Reboot and F. Reset Time options by selecting the respective checkboxes. But, ensure that Re-Partition checkbox is chosen, only if a .pit file is added in the previous step in ODIN.

Step 9: Verify if Step 7 and Step 8 are done correctly. Then hit the START button to begin the flashing process.

Step 10: Once the firmware installation is complete, your phone will reboot automatically and soon a PASS message with green background appears in the left-most box at the very top of Odin. Now, safely unplug the USB cable to disconnect the device from computer.

The Galaxy S4 GT-I9500 is now running on Android 4.2.2 UBUAMDK Jelly Bean official firmware. Go to Settings > About Phone to verify the firmware update installed.


If the phone is stuck at boot animation or Samsung logo after Step 10, then go to recovery mode (press and hold the Volume Up, Home and Power buttons together) and perform Wipe data/Factory Reset as well as Wipe Cache Partition before tapping reboot system now. NOTE: Use Volume keys to navigate between options and Power key to select an option in recovery. Please note that performing a data wiping task will only erase the phone's internal memory data, but not the contents of SD card.
