Solved Fanvil C600 V1 how do you get 3cx Authentication Prompt to display again?

[FGCUHank]

I have a Fanvil C600 V1, I used the instructions at this link https://www.3cx.com/sip-phones/fanvil-c-series, performed a factory reset and installed the C600 HW1.0 firmware from the link in the document. The web interface now shows 13.306.238.28D

The issue is in step 8 you key in the user name and voicemail pin as the password. I flubbed this step and keyed in the sip password.

My question is how do you get back to the authentication view? I tried a factory reset, clearing everything and also re-flashing the same firmware.

Thanks in advance.

Resolved and wanted to post back. I went into Extensions in the 3CX console and selected regenerate. Then I went on the phone performed a factory reset, waited 15 minutes, performed a second factory reset and on boot the phone displayed the 3cx Authentication Prompt again.

Odd but hope this helps.
