What is the difference between the signed version and the unsigned version of mobile phone software? Where is the main performance?

A signed version is software that can be used directly without a certificate.

For the unsigned version, you need to use the serial number of the mobile phone (enter a string of numbers displayed in *#06#) to apply for the certificate, and then use the signing software to sign the certificate into the software before you can install it, otherwise you will be prompted that the certificate is invalid.
