No, I haven't found a solution to this problem.

Could you please help me with it? Thank you.

you have to change stored PIN/Security code in ECM.

unsure if is possible with offline DPS as you will need to calculate Seed key

First check seed key, if all 00 00 00.. or FF FF FF.. - ECM soft bricked or modded
