Lexia 3 Interface Change Revision Serial

[lucim12]

Hello everyone
i've searched everywhere but cant seem to find solution

I have a lexia 3 interface with 921815 C revision serial which I updated from 921815 B wich was working fine for few years


Recently I reinstalled Diagbox 7.82 and the interface is not recognized by the software anymore
Diagbox 7.82 says Please connect VCI
Diagbox 7.02 says Communication with intarface card impossible
in windows it is recognised correctly and drivers and usb are ok

The problem is I think now the PSA interface checker shows Revision Serial 962830 C
so somehow it changed the revision serial number

so question is how to revert the serial number back to 921815 C

also tried older versions of diagbox and firmware but same result
