Hello ,
Small problem here ! After reading that a downgrade would be possible from the iOS7 i installed it on my Iphone 4s ! I know you have to be a apple developer bla bla bla
After one day i realized that battery is really bad and the bugs are ohh so many ! And tried to downgrade to 6.1.3 !
Entered DFU mode Alt + click restore (on Mac) instalation when on but after i had the Language and Wifi screen and the END , i am now stuck in the :
"This iPhone is currently linked to an Apple ID. Sign in with the Apple ID that was used to set up this iPhone ! " screen !
I tried reeinstalling to the iOS 7 (dfu , etc ) and got stuck in :
"This device is not registered as part of the iPhone Developer Program.If you are a member of the Program, please register your device in the iPhone Developer Program Portal."
Could anybody help me with this ?! It's been bugling me for the last , i'm not going to lie 10 hours i think !
