I have Sony Xperia L C2015 - Android 4.2.2 - 15.3.A.1.17
I have done Root access successfully, and my Bootloader still locked, I used this method to root my phone " http://forum.xda-developers.com/xper...-1-12-t2591290".
Now I need to make Factory Reset to clean everything then Reroot then Install my apps in a clean condition .
Now the question is:
How to make factory reset and return back to the original condition of the phone?????
Knowing that I'm not an expert, so please anyone give an easy tutorial
I appreciate any help ... Thanks
