BMW DME MS41 immo off please

[magnacin]

Hi,
I have the file for a BMW MS41 ECU and need immo off. I have data explorer manager and ecuvonix software but they say need to change checksum. To be honest, I really don?t know how to. Can someone please help me to do immo off or show me how to change checksum.
Thanks in advance.
Attached is file.
