Help with root on 6039Y

Hello,

first of all my idol has locked bootloader.

I just resized /data partition to 16GB, and it is working no problem, but I can not root it ( install supersu.zip).
After installing supersu.zip, on the /system partition are su binaries and SuperSu apk etc. so the zip file is flashed right way but, after rebooting the device I can reach the device via adb shell, and do whatever, but It is not booting :(

Is there any special supersu.zip package for our device? or Do I need bootloader unlocked?

Thanks for help :))
