Dear all,
FYI, I already rooted my phone without unlock the bootloader. It's quite simple, just download the program from the unlockroot.com. Install it on your PC, run the program. Plug your phone into USB and hit the root button. Finished. The SuperSU then will be installed on your phone.
Now I can manage my CPU frequency, install new font on my phone and also manage my memory. Hope it will be usefull for you all
Cheers
