Hard reset Xperia M without using Setting/Menu?

[Update_BUG]

Hi,

Is any way to activate factory settings without go to Menu>Setting>Backup&Reset>Factory DATA reset?

For Example While I power UP, I hold Power and VOLup keys but Did not activate anything?:smileysad:

No,that is the way to do it.Or using a computer you can do a software repair.

As said above you can use a computer:

In PC Companion, press start on Support Zone > Start on Update the phone/tablet software > Press the blue link that says "Repair phone/tablet".
