Interpreting Signing Error Messages in S60 3rd Edition

It seems the new security feature in Symbian 9 has led to frustration for some developers. I would like to share what kind of error messages I have seen when installing signed/unsigned application in S60 3rd Edition phones. There is a hint that explains what may cause a particular message



Error msg: Certificate error. Contact the application supplier.






Cause: You may have tried installing unsigned application. Note that signing is mandatory S60 3rd Edition.

Solution: Use our self sighning tool to get rid of this message and install the software succesfully

Error msg: Required application access not granted




Check that your certificate can be used to sign all capabilities needed by your application. For example, if you use self-signed certificate, you can only sign basic set capabilities, i.e. NetworkServices, ReadUserData, WriteUserData, LocalServices and UserEnvironment. If your application requires one of the extended capabilities, for example SwEvent, you cannot sign it with self-signed certificate. In this case, apply for developer certificates from Symbian Signed.


Error msg: Unable to install a protected application from an untrusted supplier.



If you use self-signed certificate, make sure that your application uses unprotected UID, i.e. 0xA0000000 - 0xAFFFFFFF. If you use protected UID (0x20000000 - 0x2FFFFFFF) or legacy UID (0x10000000 - 0x1FFFFFFF), you will get this message.
