MfgTool will certainly get you into diags (unless it is corrupted, but that is unlikely). You just need to follow the instructions.
If you read the sticky, you will know that fastboot does NOT write to the display, so you will see the kindletree screen while you are IN fastboot mode.
What does "didn't work" mean? What were the symptoms? What is the USB VID/PID when you go to fastboot mode? How do you KNOW that fastboot mode did not work? Which fastboot tool did you use? What host OS did you use? These questions were asked many times in the sticky, yet you did not provide the answers that you would have known that we need.
It helps to do your homework before asking questions, and starting a new thread as you did instead of adding to the relevant thread indicates that you probably did not even attempt to read the thread or try to solve you problem by following the instructions provided there.
How can we even begin to help you if you have not read the debricking information that we have already provided?
