Well, it didn't worked - i.e. Kindle's ugly pictures appeared after I've updated from 5.3.1 to 5.3.3.
Then I've uninstalled hack with uninstaller provided, put empty file "last" (putting empty file "cover" still gave me ugly Kindle's pictures) and that saved the day. Now I have last reading page and inscription "Press the power switch to wake"
P.S. My Kindle is unregistered and never get online, wi-fi is always off. When bought it, put jailbrake, kindlet jailbreak, update_linkss_0.7.N_install.bin and coolreader. After updating, put kindlet jailbrake and seen those ugly Kindle's screen-savers.
