Anonymous users2024-02-08The third version of S60 has made significant security improvements, with stricter regulations on third-party software installed and running in the system.
Some operations involving the software and hardware security of mobile phones, personal information security, etc., have been specially restricted (for example, automatic start with the boot of the mobile phone is one of the restricted functions). In order for an application to implement these "specifically restricted" functions, it must be "signed". In other words, someone has to be responsible for the safety of this operation!
Programs that are not signed cannot be installed and run
2. Put the "certificate" in **?
In fact, the certificate is not simply placed in a folder, the certificate is used to sign the software that needs to be "signed". Don't lose your certificate, because a certificate is valid for 6 months and can be used to sign a lot of software. If the certificate expires, you can apply for a new certificate, or you can adjust the time of your phone when you install it.
The time can be adjusted to the validity period of the certificate.
3. What should I do if the message "Certificate Expired" or "Certificate Invalid" is displayed when installing the theme (software)?
1.This question is asked a lot, and the "certificate expiration" occurs because the theme and software have a maker's certificate when they are made, that is, a general certificate, and the period is generally one year. This certificate is not limited by mobile phone serial number, that is to say, any mobile phone of three versions can be installed, the theory is like this, but if the certificate reaches the deadline, it cannot be installed
The problem is solved in 2 ways:
The first is to install software that does not require signatures (such as themes and most application software), and when installing it prompts "certificate expires", you can adjust the time of the mobile phone before installation, and adjust the time to about 10 copies in 2006, and then adjust the time back after installation. You can also try it at another time. Alternatively, you can sign your theme with the certificate you applied for before installing it.
The second is the software that needs to be signed before it can be installed (such as various fonts, callers, etc., generally this kind of software has a statement to be signed before it can be installed or the software name has the word "unsigned"), and it prompts "certificate expires" when installing, or you can adjust the time of the mobile phone before installation, and the time can be adjusted to the validity period of the certificate.
2.When "invalid certificate" occurs, most of the software that needs to be signed does not have a signature, and it can be solved by signing it yourself.
