Can anyone change the ISN in the MEVD 17.2 ?
Im thinking to read the valid ISN from CAS and then insert that to new donor DME

No, u have to read isn from DME and inset to CAS. This is correct way.

If I do this way then I will lock out the 8hp19 trasmission security since the tranny shares the same ISN. I believe that I need to just change the ISN in the donor DME

I think mean to read ISN from the old non working DME and write it to the new one
I am a newbie to the BMW security stuff correct me if I am wrong please.

You can read ISN from the ol dmodule if the module communicates or you can read the same ISN from CAS module. it does not matter.

I did that with a mevd17.2.3 a couple months ago. Read from the original, wrote to the donor. Did it with Autohex but also tried CGDI, which had no problems with it. If I remember correctly, a 2018 Mini, according to my bud who brought me the ECUs.

Here are the P Flash and D flash of the new donor DME
The new ISN below needs to be written in
If You could also adjust the VIN that would be awesome.
I have sent the VIN over the PS

ISN F9 31 OB 7E BB 52 81 2A 68 3C 02 82 DE 31 57 C2
