Interpreting Signing / Installing Error Messages in S60 3rd Edition
Message: Certificate error. Contact the application supplier.
Hint: You may have tried installing unsigned application. Note that signing is mandatory on S60 3rd Edition. You can use self-signed certificate or developer certificate from Symbian Signed to sign your application. ! Or simply Hack your phone. ! Message: Unable to install. Constrained by the certificate.
Hint: This message pops upwhen you attempt to install developer certificate in the unsupported device. The developer certificate from Symbian Signed can only beused in a limited number of devices. Remember that you have to send your IMEI's to Symbian Signed when requesting certificate.You cannot use the certificate in other devices that is not in your IMEI's list. . !
Message: Required application access not granted.
Hint: 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. Network Services, Read User Data, Write User Data, Local Services and User Environment. 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. !
Message: Unable to install aprotected application from an untrusted supplier.
Hint: 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. . !
Message: Unable to install.
Hint: This message may come up when your installation file (.sis/.sisx) copies files to other application's private folder,i.e. /private/uid. Note that Symbian OS9 introduces data caging concept, it means you don't have access to other application's private folder.!
Message: Expired Certificate.
Hint: Do this. . . Set the phones date back to year 2007-2009 to trick the apps/games to install without signing. . . Or simplyHack your phone. !
