Self-signing requires signing software! Signature software can be applied in all major forums of mobile phones! S60 third edition self-signed is better! Software signed with signature software can only be used by yourself, and no one else can use it! Because the signature software used its own mobile phone serial number when making it! The signature software has the permissions of 13, 15, 17, 19, and the application in the forum is generally 15. Other people with high authority can also apply, but they need money!

Signature software should only be used for the signature of sis software, because the third edition of s60 improves the security of the system! So many softwares can't be installed on mobile phones without authorization. It is precisely because of this policy that we have the following countermeasures. Signature software is like this, identifying the system as unsafe software, deceiving the system through the signature of signature software, and becoming trusted software!

To apply for signature software, you can go to Ba Shen, Lexun and other mobile websites to apply! Just provide the model and serial number of the mobile phone and go there to download and install it two days later!

I am a rookie! Please don't laugh at mobile phone experts! If you have any questions or higher opinions, please reply! Everybody communicate more!
