Try running checkra1n -v -c in a terminal.

I tried, It exited of dfu mode now the device continue turned off and wont turn on

[BradConde]

when I tried to force restart, It return to dfu mode again

[nergzd723]

Maybe you should restore with iTunes then, usually DFU mode ends when the cable is unplugged.

You can try to install MacAPP i4tools, it has plugin checkra1n, it can jailbreak my 6S success, but cannot jailbreak again, I don't know why
