Hey I have an iPhone SE I'm trying to update to iOS 10/11 (currently have 9.3.3) Downloaded the relevant IPSW. It started with error 3194 which I solved by changing the HOST. Since then I'm having error 3600 which I'm unable to solve (reset PC and iphone, changed USB port, cable). Tried it on 3 different PCs and same result: 3194 > HOST Fix > 3600 What can I do? Need to update version... Thanks !
