Destroyer of Kindle 4

Hello! I am new here, but i am a long time reader of the forumposts. So ... with that said, I tried to rebuild the Kindle-Literature-Clock myself, I managed to do all the right things until I made the final mistake (starting an ./-command in USB-Mode), resulting in a Kindle 4, showing now an all white, blank page, that does not react to anything anymore. This is what I wanted to share. Thank you!
