Any ideas how to do it without screen? I've followed the steps from my other screen, but it's hard to tell if it worked.
Go to your account on amazon, manage your kindle and deregister there. You do not have to have the kindle powered at all.
As far as your content, use a pc and wipe the files. On your kindle do a Hard restart. Again you do not need to see the screen for this.
