I used to use a Kindle 4 with duokan what did work great for all formats and books.
Now we own a new "Kindle Paperwhite Signature edition" but if
I copy books onto it (via USB) only a few of them are displayed.
I suppose "Signature edition" means only from Amazun signatured books can be displayed? As it is impossible to unlock the bootloader and install other oprerating systems via locked serial port I wonder if there is any possibillity to display all Kinds of books?
What other possibility do I have to to stop the analysis of books before they are (not!) displayed?
