Hard Reset on Kindle Fire HD

[bawalker]

Hello all,

I have a question on how to perform a hard reset on a kindle fire which has been locked because the password was forgotten.

This is for a friend whose son installed SpydrSafe software and subsequently forgot the pin/password on the Kindle and now my friend can't get to the More -> Devices menu to go through the normal deregistration steps and factory reset steps inside the software.

So is there any combination of buttons that can be pressed to initiate a hardware reset not involving using the Android software?

Thanks!
