Default Dead cellphone (MK5 Telus)

So I was flashing an updated kernel for my CM11 based ROM, on my SGH-i747m. Something I had done dozens of time before and it always worked flawlessly. This time, however I got out of TWRP and tried to reboot as I usually do but it never rebooted. I'm stuck with a nice little plastic toy, there's nothing not even a flashing led when I push the power button. Could it be what's called a sudden death? I tried removing the battery for a minute or two but it didn't work either...
