Perhaps you should downgrade to 5.3.1, re-jailbreak, then upgrade to 5.3.3, then re-install rescue packs and dev certificates/kindlet, then install screensavers hack (from the K5/PW thread, not the other screensaver thread), and finally add your png.
If that fails, look up the first 4 digits of your PW SN and hand in all info to Niluje.
I agree with that. Other than about the developers certs / Kindlet JB. They wouldn't matter in this instance. Of course the JB would be required (to run the installer).
