Bose Powermatch 8500 panel lock code

Hi

Is there any of the old Bose guys left in the group?

I can’t unlock the PM8500 amp.
I have tried via CSD but it also ask for the code her.

And I can’t update to latest firmware.
I have updated one at the time but the last one doesn’t work.

Hope somebody has the golden answer, at least to the code thing.

Kim regards
