ROTTING ANDRO LWW

Rooting your mobile may void the warranty and you are doing it at your own risk. Sony would be in no way responsible for any damage

Hi all.

I decided to make another simplified guide just for Rooting.
For flashing firmwares, see the Guide Below

{GUIDE} Install ICS ( Ice Cream Sandwich) on Xperia™ Smartphones, Root and Downgrade to Gingerbread

All has been tested so don't ask if it would work or not.

This post is for 2011 Xperias. For 2012 Xperia See 1.

Follow the steps  connect your mobile and flash.

Flashtool may show error after flashing kernel, no worries. Even your build number, android version won't change. Everything would remain same. So please don't go to phone settings to check anything

4) After flashing restart your device, It may not start completely, may remain at Sony logo or blank/black.

Whatever the status is, just restart your device and proceed with the rooting--->

( Make sure you close flashtool before running the rooting toolkit )

Now  connect your mobile to PC and Root Your Phone
