Samsung has just pushed out Android 4.2.2 Jelly Bean update, with build number XXUBMG8, for the NFC variant of Samsung Galaxy S2 Plus bearing model number GT-I9105P, starting from Germany. It is expected to reach other parts of the globe soon.
The new software upgrade, as Sammobile notes, brings improvement over performance: TouchWiz enhancement (expect some features from the Galaxy S4), Android 4.2.2 features such as lockscreen widgets, Daydream screensaver mode and a dedicated toggle section in the status bar.
Android version: 4.2.2 Jelly Bean
Build date: 24 July, 2013
The I9105PXXUBMG8 build is available as Over-The-Air (OTA) update and through KIES server as well. To install the OTA update, ensure the phone has a stable internet connection. Head over to Settings>> About device>> Software update>> Update to check for update. Click OK to download and install the update.
Those who are outside Germany and failed to receive the OTA notification for being region-specific, may follow our step-by-step guide to install the same manually. The I9105PXXUBMG8 is an unbranded version of firmware and can be installed on any GT-I9105P units (unlocked version).
IBTimes UK reminds its readers that it will not be held liable for any damage to the device. Before installing the official firmware, users are advised to verify that their devices meet following requirements.
1) Install USB Drivers for Samsung Galaxy S2 Plus to connect the Android device with the computer.
2) Enable USB Debugging Mode on the phone to connect it with the computer and use Android SDK with it. [Press Menu>> Settings>> Applications. From there navigate and click on Development option then check the USB Debugging Mode.]
3) As the tutorial is likely to wipe out all data of the phone, create a backup. If the device is having any custom recoveries such as CWM/TWRP already installed then backup data using the recovery.
4) The battery of Galaxy S2 should have charge above 80%.
5) The device should be factory unlocked and not locked to a particular carrier.
6) The phone will lose custom ROM with the installation of official firmware. Additionally, it will lose custom recovery such as ClockworkMod/TWRP which will be replaced by stock recovery.
7) The device will no longer belong to a rooted version with the installation of official firmware.
8) The XXUBMG8 Android 4.2.2 Jelly Bean leak firmware works only on Samsung Galaxy S2 Plus GT-I9105P. As flashing this on any other variant might brick the device, verify the model number of the Galaxy device by navigating to Settings>> About device>> Model number.
