      cazketer, first you must download and install the latest Sony PC Companion to your PC. Once you installed it, connect you Xperia ZL to your PC via USB connector, once your ZL connected to your PC, Sony PC Companion must have a message regarding the new update. Follow the instruction given by the PC Companion on how to update your ZL phone.

    hey man, thank for the Firmware. Helped me a lot.
    Mind you, I have NOT UTILIZED THE FULL FIRMWARE, but only the KERNEL.
    Had bricked my XPERIA ZL by accidently flashing the wrong KERNEL.
    Also, let me know, if the firmware is stock or if I flash the full firmware, then will I get a ROOTED phone???
    Waiting for your reply.
