NOTE : THIS PROCESS IS UNIVERSAL FOR ALL XPERIA DEVICES FORM OLD TO NEW. BUT IN THIS TOTURIAL I AM USING XPERIA C.
I have seen too many people having issues regarding software of their Xperia C. Lots of people requested me to make a thread on it but I was busy so didn't get time to make but wait is now over my thread is under work. So let us investigate why users face issues First thing there are many things regarding software issues E.g : Soft Brick , Hard Brick , Bootloop , Freezes. After looking on internet I found steps for it.
Now, let's move on for the process of fixing the problems

Then hold on power and volumer down key simantaneously and insert USB wait for sometime your device will get defected by PC. Please note if you have got your device really hard bricked then your device will get disconnect several times during re-install process clam down keep patient re connect your device as soon as it get disconnect ...
