Jailbreak my android (2)

After the container, microSD card, is set, it's time to jailbreak.
I tried some applications for that.
First, I tried one of the most famous root application, z4root.

But it says:

"Please do not install this application: 

z4root 

This application contains the codes that attempts to bypass Android's security "

The check box was followed by the message says "I understand it and continue installing."

   

  

Then, the security warning came out.  It says 

"Security Warning:  There are some concerns about the security 

Name: AndroidOS_LOTOOR.ISO

Application: z4root

Please delete this application." 

  

[Delete] [Close] 

  

  

Then, another message came out says: 

  

"There were some problems.  z4root is closing."

[OK] 

The next one I tried was Framaroot.

 When I start this application it says: 

 "Please do not install this application: 

Framaroot

This application contains the codes that attempts to bypass Android's security "

The check box was followed by the message says "I understand it and continue installing."

  

  

This time, it says: 

  

   

Next one was towelroot.  When I run this program, it says:

  

  

"This phone isn't currently supported."

   

    

The last one was Key Root Master.
