Hi guys, this is my first post here. I have an Iphone 4s running iOS 5.1.1 which is jailbroken. I wanted to update to 6.1.2 and jailbreak again, but the thing is i can't update the firmware with iTunes because it keeps giving me all kind of errors my idea was to "restore" to 6.1.2 through iTunes and then use evasi0n but i can't even get to 6.1.2. Can someone help me please ? Thanks a lot !
