[HELP]My Z1 LP .242 Booting longer and doesn't show homescreen topic

Hi, I have a problem. I'm using Z1 C6903 running lollipop .242 and rooted. When I finished changed apps or backup something via TWRP, I restarted my phone. Suddenly, my phone is boooting longer and doesn't show homescreen :(

I tried to hard reset twice, switch on my phone and still booting longer...Why ??

Any solution ?

Thanks
