how hard reset Motorola MB501 Quench

How can I make a hard reset on this model? I have done the following:
1. Holding the Camera button while turning on your phone,
2. When prompted hit the Volume-Down rocker button to go into Recovery Mode.
3. After you get into Recovery Mode,

But I cannot do the following, because this model does not have a keyboard.
4. Press ALT+L to reset, then Menu+Back to reboot.
I need to hard reset this phone because it is not reading the sim card anymore. The client tried the wrong subsidy code many tim
