Install Deleted Authority/Security Certificate on Nokia Phones

Does your nokia phone shows 'certificates not on phone or sim'? If so, you need to install deleted authority certificates on your Nokia phones. Here is how.
Sometimes after flashing or updating the Nokia phones’ software, we lost the security certificates used for code-signing in JAVA applications. Without these certificates, the applications would not work. They give the following error “certificate not on phone or SIM”. After working for a long time, finally I got the perfect 100% solution for these problems.
