Hard Reset Sony LT29i

[Zhaslan]

Hello from Kazakhstan. I do not speak in English (translated by google).
Cant do a hard reset on my phone. I press the power button and volume up button. But do not fall into the hard reset menu. Prior to this, the combination worked buttons. Tell me where the Problem.
All thanks

Are you saying that the power button doesn't work at all?

[Zhaslan]

Working. But she simply turns the phone. And I need to enter the service menu that would make a hard reset the device.

So what's wrong with the phone? 

Turn it on > settings > security > factory reset

Thank you, I did it. But a software reset. Hard Reset is another. I have a problem with the sensor and gps usb connection

This phone it's no longer supported so you will have to use flashtool or Xperifirm

I forgot to write. the computer sees the phone only as a sd card. on usb debugging is enabled. pervasive nature of installing the software from the phone to the computer connection is dropped
