Error messages on Symbian - analyzed

Why people love Android is because of its simplicity. Symbian interface seems made for geeks and can look very complicated at times. Nokia have tried out their best in making Symbian^3 user friendly. But nothing is perfect... I cut my 'geeko-philosophical' thoughts here and present you some error messages you may experience on your nokia and their explanation.

1. Certificate error. Contact the application supplier :You may have tried installing unsigned application.
Signing is mandatory Symbian.
You can use self-signed certificate or developer certificate from Symbian Signed or OPDA to sign your application.

2. Unable to install. Constrained by the certificate : This message appears when you attempt to install developer certificate
in unsupported device. Dev certificates from are IMEI specific.

3. Require application access not granted : With 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 you self sign an application that requires one of the extended capabilities (example SwEvent) you cannot sign it with self-signed certificate. In this case, apply for developer certificates from OPDA

4. Unable to install a protected application from an
untrusted supplier
: It is because application requires access to protected UID.
Solution : If you get this message it means you need to hack your phone to install it. But I strongly recommend not to hack.

5. Unable to install : This message may come up when your installation file
copies files to other application's private folder.
Solution : Hack your phone.

6. Expired Certificate : Certificates are valid for only a limited period. Installing an app signed with an old certificate can give this error. Solution : Set the date to 1-2 year prior than the current date.

7. Online certificate check failed : May be due to internet problem.
Solution : In Application Manager->Options->Settings Change Online certificate check to Off.

8. Application is not compatible with phone. Continue Anyway? : The application was made for S^1.
Solution : Do not install. Search for version compatible with your phone.

9. "General: Memory Full.
Close some applications and try
again"
: RAM is full.
Solution : Close some apps. Or restart phone.

10. "General: System Error" : It may be due to a variety of known causes.
