There was plenty of time to downgrade your iPhone / iPad from iOS 8.4.1 to iOS 8.4.
If you missed that boat, then you have missed it forever as Apple has officially stopped signing iOS 8.4 firmware (build number 12H143).
When iOS Firmware Signing Is Stopped
We have repeated this before, and we will do it again as a reminder. If you remember, Apple keeps signing firmware for a certain period of time. Once they stop doing that, which is usually after a week or two, then you cannot downgrade or upgrade your iPhone / iPad to that specific firmware.
For example: Apple has released iOS 8.4.1 already, making the iOS 8.4 an old firmware. Apple believes no one should go with an old firmware, and that is why they have closed the signing window forever.
Which means if you are using iOS 9 beta or iOS 8.4.1, then you cannot downgrade to iOS 8.4.
And if you are using earlier versions, like iOS 8.1 or iOS 8.2, then you cannot upgrade to iOS 8.4 (you can, however, only upgrade to the latest firmware – which is iOS 8.4.1).
No Jailbreak Possible For iOS 8.4.1 Users
At the time of writing this article, iOS 8.4.1 cannot be jailbroken. iOS 8.4, however, can be jailbroken (which is why many wanted to downgrade to this firmware).
In short: Jailbreak for iOS 8.4.1 doesn’t exist. And there is no jailbreak for iOS 9 either.
To make it clear – if you are still using iOS 8.4.1, and you want a jailbreak, hard luck! There is no other way for you than to wait for an update from either TaiG or Evasi0n to release a new jailbreaking tool.
What About The Error 3195?
On your iPhone / iPad, if you follow our tutorial on upgrading to iOS 8.4, then you will bump into this error: “The iPhone could not be restored. An unknown error occurred (3194).”
Of course, if Apple allowed downgrading or upgrading to this firmware, and you still received such error, then using iTunes player would have fixed the problem.
Unfortunately, because iOS 8.4 signing has been stopped, this error is the only thing you will ever get.
As we said earlier, if you missed the boat, you have missed it forever. So the only logical step is to wait for something to happen in this iOS universe.
