How to Exit Factory Mode for Samsung Galaxy Devices

"Factory Mode" is enabled if the EFS partition of your device is corrupted.
Sometimes if you succeeded in fixing the EFS partition, you stuck in factorymode.
If you see a annoying transparency black box which contains some info about your device (PDA, CSC, H/W, TSP, TSK ...) in yellow characters ... mean you are in factory mode.

Your device must be rooted to exit this mode.

Steps :
1. Download "ES File Explorer" or "Root Explorer" app
2. Open " Root Explorer" and navigate to : efs/FactoryApp/

3. Open "factorymode" file with text editor

4. Change it from 

OFF

to 

ON

5. Save and exit then Reboot your device
If it doesn't work, do the same steps for "keystr" file
