How to make hard reset on HTC Tornado using key combination?

[notmaxx]

Hi, All

I have HTC Tornado (Dopod 577W).

I have read topic about Hard Reset using "Clear Storage" app.

I am able to start Windows, can run Start menu, but I can't start any app from there. Therefore I can't run "Clear Storage" app.

Does anybody know how to make hard reset using buttons combination?

Thank you, prompt reply would be appreciated
