Did you had device lock active? If so then maybe thats why coz I just tried installing myself and all the installation went fine and it asked me to reboot device and it was all going fine then came this screen to enter lock code and as soon as I typed the first digit it gave me that error and now I'll have to reflash as well Below is the exact error message: =========================== "Device not working properly Try updating the device software with Nokia Software Updater. if the problem persists, contact the nearest Nokia care point. Security problem (devicelockd):/usr/lib/qt4/plugins/inputmethods/libairuiplugin.so"
