[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:

  3. Thank you for taking the time to publish this information very useful! Towelroot

  4. Thankyou soo much for sharing this!! it was much needed!! i was looking for something like this!

  5. There is no doubt that play store has the largest possible collection of application and various games, but play store also has some limitations for users and some policies of play store are not satisfactory. Due to the dominance of play store, we are bound to search an alternative and thanks to those third-party App stores like Appvn apk download we can enjoy all the contents for free. Now we have so many alternatives to Appvn and can enjoy all of them hassle-free.

  6. The basic difference between a smartphone and that of the old keypad phones is the ability to download and install various applications.
