Tried to update firmware now box wont turn on..?

[Sevendustx]

I tried installing new firmware that was from geekbuying... I put the update on an SD card... Held toothpick in the audio port and plugged in the machine(square box one). The update started going through then the screen just went black... And stayed like that for a long time.... So i tried hitting some buttons on remote... Tried turning power off with remote and nothing. So i unplugged the box and now it wont turn back on...

Any way to fix this..?

Thanks for any help.

Looks promising. When the Screen is Black and the Box don´t turn on then is
Seems like the Boot Loader (Uboot) is gone.
