Monterrey, cannot access recovery mode, Please Help!

[Matt]

After installing Monterrey and executing Option + Command + R and restarting,
my iMac27 it starts to show the globe logo, but when it finishes it shows me
an exclmative sign that says: "apple.com/support -5101F.

Has anyone seen this before?

I need to enter Recovery Mode to deactivate SIP due to a couple of programs
that do not work for me in Monterrey.

Thank you for helping!

Matt.

Thank you very much for your help Alan B!

After several attempts I was finally able to access the console and deactivate
the SIP,
now I only have 1Password not working.

The problem I have in this iMac is that the EFI Mac model iMac17,1 won't
updated.

I have: EFI version found 170.0.0.0.0; expected 447.40.12.0.0

Many people have been reporting this problem for a long time, but Apple is not
responding or offering any solutions :-(
