If you have read the numerous threads before updating, you'll find out that the old methods no longer work as Sony closed the root exploit in the new update.

The "longer" way of rooting the 257 firmware can be found here:

This thread is super old... Only .534 can be rooted, then you can OTA update to .257

Downgrade to .534, root and then upgrade OTA.

Download the file here: https://mega.co.nz/#!K1QD1bSK!JkgNvz...Tuzn8IaEFhQhUI (ftf file for .534 firmware)

Use flashtool to downgrade it ( untick wipe data/cache/appslogs )

Then root it with vroot or something else.

Then it will prompt you to download .257, doing do it OTA not through your PC

It will tell you to update to 290.
However, if your bootloader is unlock-able, backup TA partition then unlock it, then install a recovery and flash Supersu flashable zip, then flash stock kernel and then restore TA partition.
