[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.

1. Your tablet's bootloader should be unlocked. Please follow the official sony instructions here:

1. boot.img - Link:
2. flashtool(not to be confused with Sony's Emma Flashtool). - Link:
3. Android 4.3 ftf. - Link:
