then you must root your device manually.

2. Enable "USB debugging" in 
 "Settings"-"Applications"-"Development" for Android 2.x or
 "Settings"-"Developer options" for Android 4.x.
3. Connect the phone to PC with USB cable, install drivers if needed.
4. Select device in ADB settings.
5. Fill values what you need to repair.
6. Press "Repair" button.
7. Press "Root" if just root access is needed.
8. To perform "Reset EFS", phone must be in download mode (power off phone, press vol.up + vol.down and insert USB cable).
   Be carefully, do not perform this without necessity and make backup before if possible.
