UPDATED: It seems that although the downgrade is possible, the iPhone activation does not seem to work for everyone after the installation is complete, the phone remains locked. It is possible that it is a problem from Apple's servers, so it might be solved during this day.
UPDATE 2: It seems that including iOS 10.2 - iOS 10.3 are signed by the Apple company, but it is possible that the activation of the phones cannot be done.
UPDATE 3: It seems that iOS 9.0.2, iOS 9.1 and iOS 9.3.3 are also signed on iPhone 6 and iPad Air 2.
UPDATE 4: None of the iOS versions signed by Apple in the morning are signed now, on any iPhone or iPad. It seems that everything was just a problem of the Apple company, it is being corrected now.
Completely surprisingly, the company Apple Lossless Audio CODEC (ALAC), began to sign a series of old versions of iOS at the moment, the American company taking everyone by surprise with its decision. We are talking about two old versions of the operating system that can be installed at this moment on its phones and tablets and that would allow to bring back to life some phones that seemed to have become unavailable for a long time.
iOS 7.0.3, iOS 7.0.4, iOS 7.1, iOS 7.1.1 si iOS 8 are currently signed by the Apple company for a varied range of iPhone phones and iPad tablets, installation can be done using iTunes. All these versions of iOS have been blocked for some time from being installed by the Apple company, but by a miracle they are allowed to be installed, at least on the iPhone and I recommend you to do it if you have an old phone.
iOS 7.0.3, iOS 7.0.4, iOS 7.1, iOS 7.1.1 and iOS 8 can be installed RIGHT NOW on:
- iPhone 5S
- iPhone 5C
- iPhone 5
- iPhone 4 (incl iOS 7.1.2)
- iPad Mini 2
- iPad Air
- iPad 4
Install iOS 7 or iOS 8 on your iPhone right now
Although I cannot guarantee you, it is possible that iOS 7.0.3, iOS 7.0.4, iOS 7.1, iOS 7.1.1 and iOS 8 can be installed on other models, but for now this is not visible in the websites that monitors Apple's iOS versions. Considering that the installation process does not start if Apple does not sign the respective version of iOS, theoretically nothing should happen if you cannot do the installation.
If you decide to install iOS 7.0.3, iOS 7.0.4, iOS 7.1, iOS 7.1.1 and iOS 8 on an old version of iPhone or iPad, then you should know that you are giving up many security improvements offered by the American company. More than that, you also give up a lot of functions implemented over time, but at least you will have a mobile phone that is finally functional, as it was when it was launched.
iOS 7.0.3, iOS 7.0.4, iOS 7.1, iOS 7.1.1 and iOS 8 are very old versions of iOS and probably won't be signed for a long time, so if you've ever wanted to reinstall them, NOW is the time to do so. you do it. By installing iOS 7.0.3, iOS 7.0.4, iOS 7.1, iOS 7.1.1 and iOS 8 you will be able to benefit from the jailbreak again, so my recommendation is to take advantage of the opportunity while you can still enjoy it.
