Guys this Cas3+ it's crypted, without valid keyfob or DME ISN from same kit, it won't work

I think that's obvious, you can overwrite it with your own donor key data. Thats why the instructions are very clear. Delete the stored keys in the donor flash and make your own!

How? Does it not need to decrypt and how do you decrypt without original key data or dme isn?

I have cas data with known ISN if the poster needs it incase the solution does not work but I guess the responder knows how to do this in other ingenious ways.
