Default [Q] recovery error

I have S4 Active, no mods, no root, only auto updates (phone make 3 updates just after turn on).
So after week of use I had a camera connection problem in Camera Awesome.
I reboot in to recovery: first problem every time I got error message,
I try to whipe cache: impossible, I've got second error message and autoreboot.
Any ideas how to manage problem?
