Can't hard reset using buttons

[Lawrence Crecy]

I turn my phone off, hold all three buttons down, then I release the standby button when my phone vibrates, and then continue to hold the volume down and camera button for about 5 seconds.. Why won't it reset??

Soft Reset: By pressing down the Volume Down + Power buttons for 10-15 seconds (or until the device vibrates) you can perform a soft reset on your device. This is a little bit like a factory reset for your phone's OS only you get to keep all of your personal data. Think of it like restarting your PC. This is the first thing you should try if your device is behaving oddly.

Hard Reset: By going to settings>about>reset your phone you can completely wipe your phone of your personal data (ideal if you're going to send in your phone for repair or sell it). Your phone will turn off and you'll see spinning gears for a while (up to an hour or so) and when it's done you will see the same screens you saw when you first turned on your phone out of the box. You'll have to sign in with your Microsoft account again and start over.
