Hi, I currently have a jailbroken ipad 2 on ios 5.1.1 GSM. I want to restore it to the same version (ios 5.1.1) without updating to ios 6. I've been trying to restore it with ios 5.1.1 ipsw but it won't let me it keeps saying wrong build, but I know I have the right build. And I tried the gs.apple.com trick but it doesn't work still. Also, the reason why I wanted to restore is because I want to restore my icloud backup cuz some of my photos were saved there and I want to retrieve it. Thank you.
