Reset NVRAM while EFI Password enabled

I have a macbook pro (late 2011).

And, I need to reset the NVRAM / SMC.

However, I have my EFI Password enabled.

And, I DO remember my EFI Password (a lot of people in Google is searching how to reset it, anyway) !!!

When I do the following -

1. Restart

2. Press & hold CMD+ALT+P+R while booting, it prompts the EFI Pawword

3. I provide the password

4. Immediately after entering EFI Password, I press & hold CMD+ALT+P+R

5. It loads OS X Utilities, does not restart (as explained in Apple's page, the system should restart)

I have reasons to believe that the NVRAM is not reset

By the way I do not want to get rid of EFI password.

Any luck ?
