My tablet is in DNX FASTBOOT MODE, and when I enter the console, nothing appears. I've tried restoring it with adb, but it doesn't work either. I can't put it in safe mode either. It's a Nextbook model NX16A8116K. Please tell me if there's a way to fix it; if not, it might be time to throw it away for good. I've been trying to fix it for several days, but my conclusion is that it no longer works.
