Looks like its hard bricked if Nothing will turn on, only way to fix would be to send it to jtag repairs, or you can wait for this thread http://xdaforums.com/showthread.php?t=2646310 we are pretty close to unhard bricking both the T989 and T989D we need to find a user with a working T989D
most of the time Jigs dont work with Hardbricks, its worth a try, you can make one in under $10.
they are overpriced here http://mobiletechvideos.mybigcommerce.com/ but just a idea of what your looking at. they are incredibly easy to make by hand.
Actually it forces it into download mode, and resets the flash counter. Doesn't always work but you might get lucky
