A Dutch iOS hackers team known as team doulCi have unsurprisingly show off iOS 7.1 downgrade to iOS 5.1.1 without SHSH blobs which is actually a small amount of data which Apple normally used to authorize and authenticate the iOS firmware updates. As iOS 5.1.1 is no more signed by the Apple, also, it falls short of many features found in the iOS 6 as well as in iOS 7. Down below a video which showing this downgrade from iOS 7.1 to iOS 5.1.1.

The doulCi haven’t published any suitable proof that demonstrates this downgrade procedure. Rather, a video displaying the iOS 5.1.1 running on iPhone 4s was published by them.
The SHSH blobs were used fairly often by jailbreak users to upgrade or downgrade iOS at will, until Apple changed its software update authentication process with the release of iOS 6, rendering the SHSH data useless, according to iOS developer Jay Freeman.
iOS 7.1 Downgraded To iOS 5.1.1 Without SHSH Blobs
Although in this video iPhone 4s seems to be jailbroken, we are not sure that this is authentic. As the team claims that they’ll provide some more details very soon that how they carry out this. They had recently launched a new tool to bypass iCloud Activation lock.
If it is the real one, hopefully the team will provide this tool to downgrade the iOS 7 devices to iOS 5 or even iOS 6 to perform the device jailbreak. As soon as we find anything new, we will share that as well with you.
