In this case, try appending your license key as a "signature" to the module. See my earlier post for details.

Will try that. This is new territory for me though. How does this signature coexist with the already existing signature for the signed cod?

[klyubin]

All signatures are appended to the end of the module. You can freely append one more -- this won't overwrite or remove the previously appended signatures (those obtained via the Signature Tool). Also, since your signature will use a non-standard signer ID, the OS will not be automatically verifying it against the contents of the module.

Cool! That seems to be the solution then. Thanks a lot!

Ps. I mark your first post as the accepted solution.

[klyubin]

I suggest you first confirm that it works for you.

The solution worked for me. But only 128 Byte signatures worked. If more data is needed you have to divide it into more signatures.

[klyubin]

Interesting! Have you tried modifying the value of the "signature length" byte?

[dawmat]

Yes I did, signature was ok in the signature tool. But on the device the returned certificate was equal null.
