Lenovo Android Cellphone does not open

Hello,

Friends,


I have Lenovo s860 smartphone. My cellphone does not open. I see only "Lenovo" "powered by android" in the screen. This device all in one (batterie, memory etc) also i have too many data (my daughter pics and video) and this data important for me.
I open the recovery mode i see "reboot" "install update package" "wipe user data" "power off" What can i do for this problem.
