[SOLUTION] No lockscreen and No power option [Work on all Devices]
Guys most of us encountered a similar problem like this - for no reason the lockscreen and power option menu wont work
sometimes you will get red warning like 'factory mode is on'
some features wont work properly
Guys it's because of Corrupted EFS folder
So here is the exact solution
to get rid of factory mode into user mode [get back your lockscreen and power option menu]
Its a proven method
You have to root your phone and install Terminal Emulator from Google Play.
Open terminal emulator and type as ;
echo -n ON >> /efs/FactoryApp/keystr
echo -n ON >> /efs/FactoryApp/factorymode
chown 1000.1000 /efs/FactoryApp/keystr
chown 1000.1000 /efs/FactoryApp/factorymode
chmod 0744 /efs/FactoryApp/keystr
chmod 0744 /efs/FactoryApp/factorymode
You now should not see the that message anymore. Its because of an EFS corruption.
Hope it helps!!!
