Hi all. I will try to write an tutorial for all who want to root your new update firmware.
First lets consider that you have updated your firmware and booted at least one time.
Now what we need is: one PC,cable to conect your phone to PC, and 2 tools: TWRP 2.7.1.1 for KK and Superuser.
Lets begin.
1. Connect your phone to your PC and install phone drivers correctly.
2. Copy superuser.zip on your SDCARD.
3. Disconnect your phone from PC.
4. Extract files from TWRP 2.7.1.1 archive on some folder on your PC.(Remember the folder
)
5. In your folder that you extracted your archive you should find recovery.img and one scatter file.
6.
Now you must have this FlashTool - SP_Flash_Tool_v3.1304.0.119. Not Optional.
7. Power Off your phone.
8. After power off your phone open FlahTool and browse for the scatter file your folder where are the recovery.img and scatter file.
9. Now comes the tricky part
.
10. Load the scatter file and mark DA DL with check sum. Recovery.img should appear checked.
11. Press Download NOT FIRMWARE UPGRADE.
12. Now, just now plug the cabble on your phone. Download should start and a green circle should appear.
13. After this you should have custom recovery TWRP installed.
14. Reboot at least once. Then reboot to recovery by powering off your phone and restart with vol + - and power butons pressed.
15. From TWRP flash Superuser.zip.
16. Voila you have your KitKat rooted.
17. Now go to Magazin Play and download an RootChecker app and verify.
Hope this helped. For me worked with no mistake.
Waiting for feedback.
