Being the smartest is one thing but being tough enough to sustain through some real world benchmarks is different. The toughest phone amongst the 2012 pack of Sony Xperia phones, the Xperia Go is one of it’s kind as apart from having IP67 certification against water and dust, the Sony Xperia Go holds evenly as a power packed Android device at it’s heart. The prized droid is one amongst those who make the most out of their own limitations. Although the resolution has been kept at 320×480(HVGA) it still out performs it’s WVGA siblings by a great margin courtesy the same chipset humming inside as it has to do with the lower resolution with the same power within. The device fared out well with the supplied Android 4.0.4 firmware and now it has been treated with Android 4.1.2 Jelly Bean by it’s OEM as promised. Although the firmware is available to be downloaded to your phones as an OTA in select regions for now but there is another way to get it done too. The firmware will soon be seeded to more parts of the globe but there is still a group of core users who went on to unlock the bootloaders and played a few tricks out on their phones. For them, it is the Flashtool that does the trick![box type="shadow" ]Since this update will wipe all data on your device, we recommend you backup data using our backup guide and have the latest drivers installed on your PC.[/box]
Steps to Update Sony Xperia Go to Official Jelly Bean Firmware
- I assume you have downloaded FlashTool from our device drivers page. Open the FlashTool folder (it might be in C:FlashTool) and find the drivers folder. Right click on it and select “Run as administrator” and install the drivers for your phone. Make sure you check the flashmode and fastboot drivers at the end of the list.
- Download the required Official Android 4.1.2 firmware for Xperia Go ftf file(Compressed and split into 55 parts, use HJSplit to join) or download the ftf file as whole. Extract all and place the Xperia Go (ST27i)_6.2.A.0.400 (JB_4.1.2)_Hongkong.ftf file in the firmwares folder found inside the FlashT0ol folder.
- Run FlashTool.exe file. FlashTool opens and it must say “Device disconnected” at the end.
- Turn off your phone and boot it into flash mode. To do this, press and hold the volume down button and inset the USB cable that is already connected to the PC running FlashTool. You must see a green LED light up on your phone.
- FlashTool now says “Device connected in Flashmode”.
- Click on the thunder icon at the top left in FlashTool, select Flash mode and then select the ftf file you placed in firmwares folder.
- Click on OK button and the ftf file will be flashed to your phone.
- Once the process is finished, FlashTool says “Finished!” at the end.
- Disconnect your device from PC and reboot it.
Once your phone booted up properly(This may take a bit longer than usual!), you are all set to enjoy the latest official upgrade that’s available for your device. Further, make a note that since this is an official firmware, you’ll have to loose the root access after the installation but the Bootloader remains unlocked.
