I was going to test Air UI from Nokia Store, and after the required reboot I get a warning from security system early in the boot and phone doesn't advance from that. I'll update the warning later here. The first boot took longer than usual, and I got as far as typing my PIN when the phone crashed. After this the aforementioned situation. My phone had a couple of weeks old Nordic pr1.1 firmware flashed with flasher and downloaded with Navifirm. No problems this far. Dev-mode enabled for terminal and packages with htop and energy profiler installed. Landscape-hack enabled. Update: The error during boot is: Security problem (devicelockd): /usr/lib/qt4/plugins/inputmethods/libairuiplugin.so Also as an important detail I had Harmattan dev repo enabled along with rzr and the rest from wiki.meego.com.
