Closed How to downgrade ios 11.0.3 to ios 10.3.3? is it possible?

[LadyKimberly]

Good Morning phc i kinda need your help. Can someone come with a tool that can sign ios 10.3.3 back? Since apple is no longer signing ipsw for my iphone 5s. Battery drain is killing me, I think apple did it on purposed.

No.

Because Apple's older firmwares are unsigned on the Apple Restore Server. So downgrading is not gonna work.

I download their firmware (10.3) 1 year ago do you think its gonna work if i flash it back? or should accept my fate running ios 11?

As i mentioned.

Older firmwares by apple don't work anymore.

Because, each on every .ipsw file has a verification on it. So once it restored, it will check via Apple Restore Servers.

So once restored a older firmware using iTunes, you will get an error code of (3194).

Now its clear for me. Creepy smart phone, this will be the last Apple product I buy. I don't like the inability to revert back to an OS that worked well.
