hello my friend has an iphone 4 n its not unlocked or jailbroken. He upgraded to iOS 7 (ios 7.0.4 currentely) n its become very slow n laggy so he wants to downgrade it.
He dosent have cydia so i connected it to my computer n used TU to check for blobs n i got only 6.1.2 for that device, it has firmware 4.12.09
he just wants to downgrade it to any 6 ios n not unlock or jailbraek his device.
so his device can be downgraded to 6.1.2 only ryt?
n how can it be done? since i never worked on an non-unlocked or non-jailbroken devise and do i need to change his firmware or it stays the same.
