You flashed the wrong image for your box type.
Boxes come in two versions - 1xI and 2xI, and you need an image that corresponds with that.
You will now need to use IFA (Image Flash Assistant) to recover your box.
Have a look at the sticky thread right at the top of the dbox section: "HELPFUL INFORMATION - Thread locations here", and look for the Image Flashing Assistant tutorial.
