I have been following many different guides and this one worked.

Download XperiaS_LT26i_6.2.B.1.96_KernelOnly.ftf | 6.33 MB

Download FlashTool from below link, if you don’t have it.

Download flashtool-0.9.11.0-windows.exe

STEPS for ROOTING :- ( Below steps are for root 6.2.B.1.96 firmware Xperia S )

Workin on both Locked as well as UnLocked Bootloaders.

Enable USB Debugging and unknown sources option on your phone before proceeding. Do not use other kit version except V18.

Download Flashtool, Open it. Flash the “XperiaS_LT26i_6.2.B.0.211_KernelOnly.ftf” file on your Xperia S. It is the kernel of an old firmware of Xperia S which was rootable.
Reboot your Xperia S after flashing. Connect to PC in USB Debugging mode.
Do not forget to close FLASHTOOL. CLOSE FLASHTOOL , before proceeding next step or you will get serious error.
