This is what I did: factory reset in firm 5.4.4.2., installed jailbreak, MKK (for KUAL), screensavers hack, and, finally, margins hack. All is working but margins hack. I use the zip called "update_fonthack_0.4_pw_5441.zip" in this post:

And I set English UK language for the interface. Is something missing?
Thanks in advance
