[Q] cyanogenmod stuck on boot logo topic

hi guys, I've tried to install on my moto g cyanogenmod's last nightly which I've downloaded from the original cyanogenmod site, I've done everything as I've always done: wipe data,cache,dalvik,format system. Then flash cm11,gapps and pink kernel. But when I reboot the phone it won't boot and stuck on the cm11 logo, I've also wait 20 minute but notthing happen. I've also re installed the originale firmware just to be sure but there seems to be no way to make cm11 start. Could Someone help me? Thx
