Samsung is rolling out its latest official Jelly Bean firmware, Android 4.2.2 XXUBMG4, for Galaxy S4 GT-I9505 in several countries starting with Australia. As usual, the new firmware update brings performance enhancements and bug-fixes over its previous build.

The XXUBMG4 official firmware is now available for download as Over-The-Air (OTA) update as well as through Samsung KIES for S4 I9505 users in Australia. Those who have received the OTA update notification can install it officially via Settings > About Phone > Software update. However, those who missed the notification and those who cannot wait for the official release in their country can install the same manually, using our step-by-step guide.

NOTE: The installation of this firmware is done using ODIN flash tool and hence no custom recovery tool (CWM or TWRP) is required for installing the same.

Key Points to Note

  • The XXUBMG4 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.
  • Download and install correct USB drivers for Galaxy S4 on computer.
  • 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).
  • IBTimes UK reminds its readers it will not be held liable for any device damage during firmware installation. Users are advised to proceed at their own risk.
