The diag mode was working I tryed to get the system working with fastboot - with no results.
as a Second method I used k1nc instruction

and copied "update_kindle_all_new_paperwhite_5.12.1.bin" via the export USB function on the kindle and updated it.
The update worked without any errors and I got the screen working - The Tree image while updating and also the Screen while the diag mode.

But it also doesn't start after the countdown.

So far these are these my recovery attempts to get the Kindle working.

Thanks for your help.
