I solved with this procedure:

Flash an official firmware
Flash CWM recovery
Boot into Recovery
Select mount and storage -> mont /system
Connect your phone to PC using USB cable
Open ADB command window and type the following commands

adb shell

mke2fs /dev/block/mmcblk0p3

mount -w -t ext4 /dev/block/mmcblk0p3

reboot

Now phone boot but imei is 000000000000000

It's possible repair imei with Cert file or credits?

Thanks for reaply
