[Q] Note 8.0 won't start... period. May be hard bricked. topic

A while back i used to "try" to root stuff. I sucked at it BAD. Anyway, I have a Galaxy Note 8.0 (GT-N5110) that I had rooted to a certain point (very superficial) and I just kept it the way it was, that way I could use Multi-window for any app. This morning I unplug my tab from the charger only to be disappointed that it will not turn on. Ive tried different power outlets, different cables, different base chargers, even the whole "power+vol_up+home" thing... nothing. I never updated the tab when Kitkat came through the pipeline. Im freaking out that a new major update automatically happened overnight or something. Im sorry to trouble you all, but does anyone have suggestions? Since it's rooted I can't take it to Samsung or Best Buy. Honestly if I could just get it back to stock, that would be awesome, but im more concerned about getting it to simply turn on. Any Ideas?
