    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 !

    From my understanding, Apple isn’t signing iOS 10 or 11. You can only update to iOS 12.4. You can check out ipsw.me for the latest firmware that you can update to, as well as what Apple no longer is signing.

    Thanks!
    You're right. Apple signs only ios 12.4.

    Any solution to do it anyway? Like updating without itunes or something?

    You have the blobs for iOS 10 or 11?

    If so you can jailbreak and use the various tools available to upgrade to that firmware.

    If you have absolutely no idea what I am taking about when I say blobs, then you don't have them and there is no way for you to do what you want.

    If there was an easy way around this it would have been found already and there'd be no need for your thread.
