Requires Root Access!
Instruction: Download and extract apk to phone somewhere you no where to find it. Backup the old LGKeyguard.apk and LGKeyguard.ODEX.
1)----->Install the Modded apk in th system/priv-app and set permission rw-r--r-- or permissions 644.
2)----->Next delete the LGKeyguard.odex from the system/priv-app and reboot phone.
3)----->Should get the optimizing/upgrading on reboot and hopefully weather effects on lock screen.
4)----->Make sure you have sync on and a weather widget somewhere as it seems to require them to work.(See post #34)
