How do I handle the expiration of a mobile phone certificate? What should I do if the security certi

The certificate expires and you can modify the time and date of the phone itself, so that it can be installed, of course, these must be the phone itself has a certificate, and the time can be changed, but it must be corrected. If the certificate expires, you can install the software by adjusting the system time to the validity period of the certificate (you can change it back after installation). If you can't determine the expiration date of the certificate, adjust it year by year, or simply re-sign the software with the unexpired certificate.

If it prompts that the certificate expires when installing the software, adjust the date of the mobile phone to the installation period (note that the certificate has not yet taken effect, and there will be a prompt of the relevant date in the introduction of the software that generally requires the certificate.) If you don't have it, you can only try it yourself, and the validity period of the certificate before 2010 seems to be three years), and it would be good to change the date back after completing the installation. Hope it helps.

Beginner's Tutorial on the solution to the problem of "expired mobile phone certificate" that causes the software to be unable to be installed!

There are often some "certificate x x" problems that cause the software to be unable to be installed, so let's summarize the possible problems!

The first thing to note is that the certificate has an expiration date, regardless of whether the certificate is within the validity period, it can be installed, and all you need to do is to adjust the time of the mobile phone during installation.

Then you need to explain, make sure that in your phone you go to "Settings - Phone Settings - Apps".

1.Certificate error.

The most common reason for the problem is (1) the program that needs to be self-signed is installed without signing, (2) the software signed by someone else with a private certificate (that is, the certificate that provides the serial number application), and (3) the software that is repeatedly signed (that is, it has been signed once and signed again).

Solution: (1) Install after signing, (2) Go to the software that has not been signed to sign by yourself, (3) Install it with software that does not have a duplicate virtual signature. If you don't have a certificate, find someone to do it.

2.Certificate Limitations.

This problem is not very common, but it is still annoying to appear. The reason is that the key is required to make a certificate and sign, and some signing software will prompt when the key does not match, but some still continue to sign, so that the signed software will prompt the certificate restriction when it is installed. There is also a reason why the certificate file is corrupted during propagation.

Solution: Try to change the key file first, it is best to ask the person who helped you make the certificate to send him his key file to you, if it still can't be solved, make a new certificate on it.

3.The certificate expires and does not take effect.

Each certificate has an expiration date, and only within the validity period of the certificate can be installed. But the signed software can't look at the expiration date, so you can only try it when you install it.

The solution: is to modify the phone time. Generally, the normal date will be adjusted first, and then the adjustment will be adjusted in 3 months, and the adjustment will be installed once to see the error report.

The certificate expires because the time of the current mobile phone is after the validity period of the certificate, and it can be adjusted forward, and the certificate is not effective, and the mobile phone time is before the validity period of the certificate, which should be adjusted backward (in fact, this error will not appear when it is adjusted to the correct date in many cases).

free: The solution to the problem.

1.First, it depends on whether the software you install requires a signature, and don't need to sign the software that doesn't need to be signed. Look at the file name suffix before signing.

SISX does not require a signature,sis only needs to be signed, but not allThe SIS documents must be signed. Generally, if you need to sign it, you will explain it when you **.

2.Check to see if the certificate has been successfully signed and installed before.

The certificate has been successfully signed and installed indicates that the certificate is valid and can be skipped 4.

3.Replace the software to try to sign, don't lock on one software.

4.Select whether to change the key file or redo the certificate based on the error message.

5.Basically, these few steps can solve more than 80% of the problem, if you can't install it, then ask for help.
