Apple Stops Signing iOS 9.3.1, so You Can No Longer Downgrade from iOS 9.3.2

Over the weekend, Apple stopped signing some iOS 9.3.1 firmware files — preventing users from downgrading from iOS 9.3.2. The move comes less than three weeks after iOS 9.3.2 was released to the public.

If you tried to downgrade from iOS 9.3.2 to iOS 9.3.1 or tried to restore to iOS 9.3.1, and got Error 3194 then it was because Apple has stopped signing iOS 9.3.1 firmware files., a website that provides real-time signing status for Apple’s firmware files, confirms that iOS 9.3.1 for most devices is no longer being signed. This means that attempting to downgrade to it from a more recent release will simply throw up an error. Apple is still signing new builds for some of the older devices, which were released to fix the Activation Lock bug.

It is not a major issue for jailbreakers as it was not possible to jailbreak iOS 9.3.1. Downgrading can be useful in cases where the previous iOS software update can be jailbroken. So it would have been quite useful if it was possible to downgrade to iOS 9.1, which can be jailbroken using Pangu Jailbreak. Some users also prefer to downgrade back to the older version if they face problems after upgrading to the latest iOS software update such as battery life issues etc.

This doesn’t come as a surprise, as over the last few years, Apple has used this strategy to keep jailbreakers at bay. It not only releases new software updates, that fixes the vulnerabilities used by the jailbreaks, it also stops signing the older iOS firmware file, which prevents users from downgrading back to the older iOS version that can be jailbroken.

Were you planning to downgrade to iOS 9.3.1?
