Stupidly updated to 6.0

Can I just follow the instructions for 5.3 or do I need to do something else first? I don’t have any signatures saved. I’m also completely new to this.

Go ahead and jb it to 5.3, apple is still signing this firmware. By the way, its a tethered jb. good luck

Since 6.0 is new, you don’t need to save the signatures.  Ignore Seas0nPass’ attempt to save them, and go for the JB.
