The same problem here.
Flashed the original firmware from sammobile and have no lockscreen (yes, I activated it in security settings) and also Google account setting nor the SIM PIN was asked when booting up.
Coming from a rooted GB LC1 and flashed with mobile Odin pro. I downloaded the firmware twice and reflashed 5 times (with wipe, without wipe,...).
Anyone has an idea?
Now back on a custom GB Rom, but would like to try the ICS.
Thanks in advance
Ok, here is the solution (donīt ask me, why this is necessary ):
- Download "Terminal Emulator" app from market
- open it
- type into the command:
echo -n ON > /efs/imei/keystr
and voila, lockscreen and PIN question are there.
