NTT Docomo Fujitsu Arrows X F-02E Root

http://forum.xda-developers.com/showthread.php?t=2402784

I have managed to find a bat file which will allow you to root your F-02E japanese phone.
I have also found a script to allow system R/W made by kikuhare

Steps Involved:

1. Make sure your phone has 100% charge.
2. Download the Root + System Mount
3. Extract the zip's to different folders.
4. Enable USB debugging under Menu > Settings > Developer Options.
5. Point to the folder where you extracted drivers from "usb_driver_F-02E_1.0.zip". Wait for drivers to install.
6. Make sure the phone is connected as PTP not MTP.
7. CMD into the folder "f-02e_oneclick_su_installer". It is inside the "Root + System Mount_1" files folder.
8. Run the runme.bat.
9. Download "Root Checker by joeykrim" from the Play Store.
10. Run the "Root Checker" app
11. Wait for the process to finish.
    
    UPDATE System R/W
12. Connect phone to computer
13. Download the System Read Write Mounter_1.zip <<<<<< Only need to download if you did not download the "Root + System Mount_1.zip" file.
14. CMD into the "F-02E_system-mounter" It is inside the "Root + System Mount_1" files folder.
15. Extract the file and run the"START.bat"
16. Run everytime the system restarts to mount system as R/W.
17. Enjoy root .

NOTE: This method does not give full root permissions. You will still be able to underclock the CPU to some degree and use the CoreControl app to disable cores. I will have to run start.bat inside F-02E_system-mounter folder everytime the phone restarts to get system R/W
Drivers: usb_driver_F-02E_1.0.zip
