Flashed the wrong Bootstack to my LS990,won't boot,anything but a paperweight?

This morning while trying to fix an issue with my screen nor aligning properly on both sides, I installed a bootstack for an LG G3 model other than my LS990, bricking it. I'm guessing it's a doorstop now, I just want to double check before I toss it in a recycle center somewhere to be someone else's problem.

Thanks.
