I tried to downgrade my IPhone 3gs to iOS 4.1 from iOS 6.1.6 but realized it was a 8GB model and cannot be downgraded. Now I want to exit recovery mode. I looked up tutorials and almost all of them are self promotion for their program that you have to pay to use the service to exit recovery mode. Anyone know how? And if you are nice enough, you can give me a small tutorial to downgrade my other 3gs that's a 16GB model and can be downgraded to 4.1
