smt210r dead after restoring to factory rom...

I decided to try out CM11 and while it worked it wasn't all that great so I decided to go back to factory 4.4.2 rom for this device. I use a Linux machine with Heimdall and the install completed ok but after the tablet would not boot. At all. I've tried all button combos, leaving the battery out for 1 hr, 2 hr and then finally overnight with no luck. I don't get the Samsung boot logo or anything. Just a black screen no matter what buttons are pressed so I can't get to TWRP or download mode to fix it. Any ideas on a hard reset besides pulling the battery?

Also, I don't get the battery charge screen or anything either while charging. I am using the same original charger I was using during my CM11 testing and it charges the tablet very well. It's almost like there is nothing there to even tell the board what the buttons are or what they control.... I'm at a loss.
