Unlock MIDlet: Incorrect SSL server certificate

[retryterty]

Hello,

I am working on Nokia 6212. I have a SIM Card and the unlock midlet.
Unfortunately, I have the incorrect SSL server certificate when I am unlocking the secure element.

I have old keys. Maybe I can sign the midlet like you.
But I don't know how it works.

I have tried to use a software on windowz and sign the file.
Two new files are appeared into the jar file, It is the signature also.

But the Nokia Unlock Midlet, signed, can't be launched. I have a "invalid application" error.

Would you have some idea ?

Thanksfully

Did you set date back to when the certificate you're using was valid?
