Apple stops signing iOS 10.3.3 for iPhone 6s

After a prolonged period of signing iOS 10.3.3, Apple has now stopped signing iOS 10.3.3. Here are your upgrade and downgrade options now.

iOS 10.3.3 is no longer available

Apple closed the signing window of iOS 10.3.3 permanently for all devices a while back.

As you know, Apple never reopens the signing window of a firmware version. However, they began signing it again specifically for iPhone 6s.

iPhone 6s devices that have third-party displays weren’t working properly after updating to iOS 11 firmware.

Reopening the signing window of iOS 10.3.3 ensured these users could downgrade and enjoy a functional smartphone again.

Some users pointed out that ipsw.me is still showing this version as signed. However, this is not the case here.

This site maintains a cache for a while before it updates with the latest signing information. This results in users erroneously downloading an incompatible firmware for their device.

The only real way to check if a firmware is being signed is through TSSChecker.

Here’s a tweet that shows how TSSChecker fails to fetch SHSH Blobs of iOS 10.3.3 from Apple’s servers.

What are my options now?

Downgrade

A lot of users were sitting on iOS 10.3.3 in hopes of jailbreaking it or downgrading to iOS 10.2.

Needless to say, you won’t be able to downgrade your iPhone 6s to this version anymore using iTunes.
