Nokia E63 Subject Certificate Error Seeking Explanation

Hello friends who need to get a certificate! Since June last year, due to the change of the relevant policies of the symbian certificate of foreign management of symbian certificates, it is impossible to produce new certificates, so the national mobile phone certificate production forums have stopped the production of certificates, and it is estimated that they will not be open in the future.

Current workaround:

1.For software with lower permission requirements, you can try to use the mobile version of the Symbian Direct Signing Tool to search - Symbian Direct Signing Tool, the first one. Signature, but it is not guaranteed to be valid, it can only be said that it can be tried.

2.Of course, you can also hack the phone, and you don't need a certificate signature to install any software after the phone is cracked.

However, there is a program to be signed during the cracking process, so you may need to sign the direct signing tool above.

Some software on the smartphone cannot be installed, which is caused by a certificate error and needs to hack the phone

To play smart chicken, you must learn to crack the phone

Take a look at hacking the phone.

Go to your phone's program management Options Settings Options Software Installation Selection (All) **Certificate Check Select (Off), and ignore the following. If the installation is unsuccessful, you can adjust the setting time of the mobile phone forward. For example, it's September 2012, you can adjust the time to March 2012, remember that it can be 3 months or 6 months, and you will succeed if you try more.

What is a Certificate?

1. The certificate is "the license to install Wang Zhimin's software". When you install a certain software, the Nokia mobile phone S60 version 3 system will analyze whether the software you want to install comes with this installation license (certificate), if not, the system will not let you install it. Certificates have restrictions on levels and permissions, and the lowest certificates can only be used to install ordinary games, themes, and general application software

Menu key--Application--Program Management--Options--Settings, select "All" for software installation, select "Off" for certificate checking) to avoid certificate checking and get installed, because the default setting is to turn off checking, so this is the reason why many ordinary software can be installed without a certificate. A slightly higher certificate can allow the information of the software to enter the system folder of the C drive of the mobile phone, let the software have high permissions such as automatic operation at startup, modify system parameters, etc., and the certificates that currently require our self-signature are all such certificates. The highest privilege certificate can modify the system, but you need to pay for it from Nokia.
