Solve the problem that "authentication failed, Authorization invalid" is prompted after installing the cracking software for iOS 5.1.1.

After IOS 5.1.1 is completely jailbroken, it will become more and more urgent. However, when you use itools to install some harmonious software, you will always be prompted

"Authentication failed, invalid authorization"

The installation fails.

 

Check it at night. It turns out that you still need to install a cydia plug-in called "appsync 5.0 +"

The source address of cydia is: http://cydia.hackulo.us/

 

However, I'm curious that I didn't install this stuff when 433 and 501 were jailbroken. Why didn't I try it at that time?

Is it because the redsn0w I used previously integrated this, and this time I used absinthe without integration?
