Which combination of keys does a hard reset /formating on your phone?

[Kross]

There might be a need at one point or the other to reset your phone to factory settings and you have to use combination of keys. For my phone for instance, pressing and holding the power button and down button would boot the phone into where you can format it.

Which combination of keys boots your phone into restoring factory settings mode?

For my Redmi A1, the hard reset is done by holding the Power Key and the Volume Up Key.
