HU7 - SecOC Error After Coding

[Hzr]

After coding the HU7 (coding completed 100%), I received a SecOC error when running SecOC. Then, after performing a Hard Reset, a message about the anti-theft system appeared on the screen.
If anyone can help me solve this problem, I'm willing to pay for their help. Thanks in advance.

It seems that you need to unblock the firewall first.

It's already been done, and the countdown has been completed. Is the SecOC step necessary or not?
Because after two hours, the anti-theft system screen doesn't appear, but XENTRY still displays the error.

After much thought, modern cars like the W223 and W206 require a SecOC module for proper operation of the control unit.
