Then I tried to re-root your device by supersu.zip but without success. I also use framaroot failed. I finally copied the su binary file in system / xbin and copy files supersu.apk in system / app but I still can not get root. So how to root this device. My device is lenovo-p770 rom: 4.2 JB

Hi. Did you set the permitions read write to your su binary and supersu apk?
Set like that with root explorer:
To Read colomn
To Write colomn
To Read colomn mark all
To Write colomn mark owner
To Execute mark all
Then mark Set UID and Set GID
After that restart your phone.
