Cisco 7841 phone Factory Reset using the Keypad

Hi

Does somebody know how to perform a Factory Reset on a Cisco 7841 using the Keypad? I Followed the instructions in the Cisco IP Phone 7800 Administration Guide but it didn´t work. I am trying to make this reset using the Keypad since I am not able to do it using the menu (admin setting) because it is asking me for an Administration Password that I don't know. It's important to note that I am connecting the phone to CME 10.5. The procedure I followed and didn't work is:

Step 1  Unplug the phone:
  • If using PoE, unplug the LAN cable.
  • If using the power cube, unplug the power cube.
Step 2  Wait 5 seconds.
Step 3  Press and hold # and plug the phone back in.
Step 4  When the light on the Mute button and handset light strip turns off and all other lights (Line button, Headset button, Speakerphone button, and Select button) stay green, press 123456789*0# in sequence.

When you press 1, the lights on the line buttons turn red. The light on the Select button flashes when a button is pressed.

After you press these buttons, the phone goes through the factory reset process.

If you press the buttons out of sequence, the phone powers on normally

This procedure is outdated

This procedure is outdated (if not incorrect). 

 

To factory-reset a phone, you'll need to let the phone boot up normally.  Once the boot up is complete, hit the Settings button.  Hit the unlock combination "**#" and a you'll see an "Erase" softkey appear.  

 

This is the only method.

Can someone please clarify

Can someone please clarify this? I've tried the reset procedure in the original question and the procedure in the "Correct Answer" post and neither work. In the original post, the mute button never fully lights, just flashes and entering the 123456789*0# doesn't work. In the "Correct Answer" post pressing the Applications (Settings?) key then the "**#" does nothing.
