[Sony Xperia Tablet Z SGP311] Lost ROOT after Android 4.3 upgrade

My Sony Xperia Tablet Z(Wifi Only - Model SGP311) lost ROOT after upgrading to Android 4.3.

However, the Vroot tool I shared in a previous post no longer works in Android 4.3.

The XDA link below helped me ROOT my tablet again.

I was confused about the prerequisite files required. After going through the entire thread, below is the list of files I used to successfully ROOT my Android 4.3 tablet.

Prerequisite:
1. Your tablet's bootloader should be unlocked. Please follow the official sony instructions here:
http://unlockbootloader.sonymobile.com/

1. boot.img - Link: https://dl.dropboxusercontent.com/u/97918958/boot.zip
2. flashtool(not to be confused with Sony's Emma Flashtool). - Link: http://www.flashtool.net/download.php
3. Android 4.3 ftf. - Link: http://forum.xda-developers.com/showthread.php?t=2589894

[Sony Xperia Tablet Z] Rooting Model SGP311

 The chinese app at this russian site worked for me.

http://sony-xperia.mobi/programmy/247-poluchenie-root-dlya-xperia-tablet-z-dlya-proshivok-10-3-1-c-0-136-sgp311-312-i-10-3-1-a-0-244-sgp321.html

You need to install the app on your pc, and connect Xperia Tablet Z to your pc using USB.

However, please ensure usb debugging mode is enabled by
1) Tapping on "Settings > About Tablet > Build Number" multiple times to reveal the "Developer Options" in Settings.
2) Ensure " Settings > Developer options > USB debugging " is CHECKED.
