Dear all can any one tell me whether it is possible to install official kitkat of sony on my xperia sp by rooting or by any other procedure...?
Hi there,
There is no official kitkat for the Xperia SP, you can get CM11 which is kitkat based on AOSP for locked bootloaders:
XperiaSP Locked Bootloader (LBL) Cyanogenmod 11.0
