I really appreciate your quick replies.

I have a USIM that I wanted to program. However, I am getting the runtime error for exceeding the number of attempts to enter the ADM1 key. Is there any fix for it?

Is there any way to retrieve the value of OP from OPc and Ki?

No, that defeats the entire purpose of having card-individual OPc values.

If you could just revert that operation, there would be no [security] advantage of card-individual OPc values over a global OP value, and hence that entire option could be dropped from the specifications altogether.
