Update Galaxy S4 GT-I9505 to official Android 4.2.2 XXUDMH8 Jelly Bean firmware .

Samsung has rolled out its latest Android 4.2.2 XXUDMH8 Over-The-Air (OTA) Jelly Bean firmware (September release) for Galaxy S4 GT-I9505 users in the UK. The Galaxy flagship phone is yet to receive any official Android 4.3 update from the company, while curious users can go ahead and install custom ROM updates available via several third-party Android developers such as leaked Google Play Edition ROM, CyanogenMod 10.2 ROM and Android 4.3 leaked custom ROM.

Nevertheless, those who want to manually update their device to the latest official firmware can follow our step-by-step guide with Odin flash tool.

IBTimes UK reminds its readers that it will not be held liable for any device damage during or after firmware installation. Users are advised to proceed at their own risk.


    • The I9505XXUDMH8 official firmware and instructions provided are limited to Galaxy S4 GT-I9505 model. Verify device model number by navigating to Settings > About Phone.
    • Back up data and settings using recommended custom recovery tool such as ClockworkMod (CWM) or TWRP, as data wiping process is mandatory in this tutorial.
    • Ensure USB debugging mode is enabled on phone by navigating to Settings > Applications > Development or Settings > Developer Options.
    • Double-check the device has at least 80% battery charge to prevent unexpected device shutdown (due to battery drain) while installing ROM.
    • If device is stuck at booting or experiences boot loop issues, Wipe Cache Partition and Wipe Dalvik Cache a few more times before rebooting.
    • Allow newly installed ROM to stabilise for five minutes before using device.
    • If a Status 7 error message flashes while installing firmware, it could be due to an incompatible device or absence of a necessary kernel (for instance, a Jelly Bean Kernel must be installed before installing any Jelly Bean ROM).

How to Manually Update Galaxy S4 GT-I9505 to Android 4.2.2 XXUDMH8 Official Firmware via Odin

Step 1: Download Android 4.2.2 I9505XXUDMH8 Jelly Bean OTA for Galaxy S4 GT-I9506 and Odin v3.07 on your computer.

Step 2: Extract the firmware zip file to the desktop to obtain a .tar.md5 file.

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 5-6 seconds) to confirm complete device shutdown. Boot the device into Download Mode by pressing and holding Volume Down, Home and Power buttons together until a warning triangle sign appears on screen. Then hit Volume Up to progress into Download Mode.

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

Step 6: Connect the Galaxy S4 to the computer via USB cable, while the device is still in Download mode. When the device connects successfully, a message saying "Added!" appears in ODIN and the ID: COM box will turn yellow or blue with the corresponding COM port number. If the message fails to appear, try reinstalling the tablet's USB drivers or changing the port on computer.

Step 6: Choose the following files from the extracted I9505XXUDMH8 firmware folder obtained in Step 1 by using respective checkboxes:

    • Select thePDAcheckbox, and click the '.tar.md5'file

Step 7: In Odin, enable Auto Reboot and F. Reset Time options by selecting the checkboxes. But the Re-Partition checkbox must not be selected or checked.

Step 8: To prevent ROM related errors, verify Step 6 and Step 7 are done correctly. Then hit START button to begin flashing firmware.

Step 9: Once the firmware installation is complete, the phone will reboot automatically and soon a PASS message with a green background appears in the left-most box at the very top of Odin. Wait until the home screen loads up. Now it is safe to unplug the USB cable to disconnect the device from computer.

Galaxy S4 GT-I9505 is now running on the latest Android 4.2.2 XXUDMH8 official firmware. Go to Settings > About Phone to verify the firmware installed.
