Root Sony Xperia U By Flashing Stock Rooted Kernel

These little guys are generating much of hype amongst the teen as we are here to welcome the next-gen Xperia phones. Meet the foot soldier first. Its the Xperia U but hey don’t get carried away by the way it’s placed amongst it’s siblings, it’s twice more than what meets the eye. After the introduction of ST-Ericsson’s Nova Thor STE U8500 chipset which combines two cortex-A9 cores ticking at 1Ghz each coupled by the proven Mali-400mp GPU, dual core phones are now in for a bargain. Infact, the whole of the Xperia 2012 line-up sports the same chipset with the modest of modifications as the price tag goes up the scale.

Coming back to our little customer of the ask, despite of what amount of charge this little dude generates in the mob, it looks like it is already on the way through. So, we are here to present to you the first of the rooting guides for this pin-sized powerhouse( no doubt, sony has already proven it’s metal in the compact form factor). Well, this time it’s the traditional way we are going to adopt which means, you must be having some experience with the fastboot method (don’t worry if you aren’t, we are here for that only).Once the bootloader is unlocked, it’s a matter of installing DooMLoRD’s kernel to obtain full root and install BusyBox. The phone hasn’t received any Custom recoveries but that’s okay considering it’s age in the lot, that’s why we are going to hit the fast boot method.

Disclaimer: Hack My Android is not responsible for any damage that your device may face during this process. The developer is also not responsible for the same. There are little chances that your device may face any issue. However, try this at your own risk. This process voids the warranty of your device.

Pre-Rooting Requirements:

  • You must have android-SDK installed with all the generic addons.
  • You should be having some experience in using the command-prompt.
  • Back up all apps using ASTRO File Manager. You can get the APK files using ASTRO and later restore it. Rooted users can use Titanium Backup which also backs up data along with the apps.
  • Back up all contacts to SD card.
  • Backup SMS on Android.
  • Backup call log on Android.
  • Have minimum 60% charge on your phone else you might get stuck while the update process is running on your device.
  • Remove any security or Anti-virus app if you have them installed.
  • Enable USB Debugging. This can be don by Settings>Applications>Development and making sure that USB Debugging is checked.

Steps to Root Sony Xperia U

Download the stock rooted kernel. Once you are done with installing the android SDK and downloading the kernel on your system, place it in the directory :

program files/Android/android-sdk/platform-tools/

If you’re done with that,

  • Turn off your device.
  • Start the device in fastboot mode by pressing Volume up button and connecting it to the PC via USB Cable simultaneously.
  • To check that you have the device drivers installed, type “fastboot devices” in command prompt and you should see the serial number of the phone connected.
  • Using Command prompt, cd to the platform tools folder. You can find the platform-tools folder in the location where you have installed the Android SDK.

Now all left to be done is using the following command to be entered in the Command Prompt to flash the kernel to your phone:

fastboot flash boot kernel.elf

To reboot your phone, you can enter the command “adb reboot” and your device will reboot.

So, there you go, reboot your phone and enjoy the new kernel and hey, mark my words, if you are in for more development on this phone, those who wait, won’t be out of luck forever 🙂
