i have followed all the steps using NRT to unlock boot-loader and root the phone.
Installed TWRT manager and flashed the recovery.
Now i am trying to flash CM12 for the first time and stuck with error message "can't install this package on top of incompatible data" during flashing .
downloaded the following flash zip from CM website: cm-12.1-20150901-SNAPSHOT-YOG4PAO237-hammerhead.zip (281.77 MB)
Can any one help me what needs to be done to proceed further.
