Phone Won't power on after CM update

[spyjoshx]

My phone (SPH-L710) was working fine with CyanogenMod 13 and TeamWin recovery. Today I updated CM to the latest nightly. Now my phone powers on and shows the Galaxy sIII logo but then the screen goes off and nothing happens. What should I do?

EDIT: I ca't get to the recovery or the Odin Mode.

EDIT2: I fixed it with: http://forum.xda-developers.com/showthread.php?p=43305728#post43305728

ahhhhhh, ya broke the bootloader. seems to be a bit more common nowadays. I had the same issue with a vzw i535 about 2 years ago and fixed it with the same process. Mount the bootloader img to an sd card of the same size as the internal storage and itll boot. Then you just need to copy the boot img to the internal with a terminal emulator
