Default [Q] Near brick state, or bricked

Hi. I have Nexus 7 2013 WiFi 32Gb. FLO 04.02 bootloader. Stock 4.4.2 android with root and teamwin.
Recently, I start download file and after that my nexus 7 rebooted. And it stuck on Google boot screen. I try to run teamwin, but it also stuck on Teamwin logo.
In fastboot mode i get:
