Tried to root phone but I ended up with Bootloader Exception

I tried to root my phone using this method http://forum.xda-developers.com/tmob...-edge-t3410470 but I think I failed that.
Now my phone looks like this and I can't get out of this no matter what I press.

Even if I try to hold down VOL-DOWN + POWER + HOME it gets me back to here.

Boot loader Exception

Hi All,

I have S7 Edge Without changing anything i woke up this morning and found this msg on my phone :-

Bootloader Exception
[RST_START = 0x100000000 ]
[...]
Exception: do_handler_serror: SERROR(esr: 0xbf00000000)
[...]

I checked the following thread but no luck :-

what should i do ? is there any solution i can use without sending the phone to warranty ( i am sure they will take a lot of time in my country )

I use all the key combination with no luck , the msg keeps running the phone what kind of msg is this ? how to solve it ? why it's happened in the first place ?

Thanks
