Jailbreaking Ps3 4.76!

Hi, I have been trying to jailbreak ps3 4.76 software version. I found a lot of sites with the jailbreak file but all of them are password protected. I also completed the surveys many times for getting the password but the passwords are wrong there. So does someone know any site from where i can get the jailbreak file for free? Or is there any way to open the password protected .zip file?

Try to complete more cpa offers eventually you will find one that is working
