I'm trying to install custom firmware.  At first, the Dingoo would stop at the splash screen and go no further.  Through a series of flashing, attempting to install firmware, and unbricking, I did get a change, but it appears to be for the worse.  The screen shows nothing but a bunch of horizontal multi-colored stripes.  My computer recognizes the drive, but the screen won't show anything but the stripes no matter what I do.  At this point I've tried every suggestion I could find in the forums.  Nothing works.  Please help.
