[AC Question]

I have a Irulu tablet that always ran fine that I was going to sell.
I went into settings, hit the factory restore button, checked the erase SD card and hit OK. It came up with the warning box that everything would be deleted, I hit OK. It directly said shutting down, and shut down. That's the last time it has worked. I have tried pushing every combination of buttons I could find. I've tried the reset....nothing. When you plug in the power cord, the charging light will come on red till its full, then it goes green like its supposed to. That is the only sign of life. Did I kill it?
Thanks!
