SHSH Blobs were once very useful. In fact, without them, a downgrade was next to impossible. The concept of SHSH Blobs started long back with iOS 3.x. Back then, people who wanted to get back to the older versions of iOS (because they did not like the new features of newer iOS then) could use the SHSH blobs of their old iOS versions to downgrade to the older versions.
With all the software around, saving SHSH Blobs of iOS firmware has always been easy. But one software that does all the work for you, at no cost, is iFaith from iH8sn0w. Just recently, iFaith 1.4 was released with some new and interesting features.How to Save iOS 5 SHSH Blobs of iPhone/iPad through iFaith
With iFaith, things have really got very simple. All you have to do is:
Download and install iFaith on your PC.
Connect your iPhone/iPad (running the same iOS firmware that you want to take SHSH blob of.)
And just run the software and follow the instructions!
If you want to save iOS 5 SHSH blobs of iPhone/iPad, you should connect your iPhone/iPad which is running the iOS 5 firmware. Same goes for iOS 5.0.1 too.
All said and done, iFaith does not work on iPhone 4S and iPad 2 (the A5-devices). It works on all others, like the iPhone 4, 3GS, 3G and iPad.
Apple Blocks Downgrade Ability From iOS 5 Onwards
Although, we are still wondering how far this is going to be useful because there is one big change that we have to remember: Apple has stopped downgrade ability for all version starting from iOS 5. Which means, if you had upgraded to iOS 5.0.1, you would not be able to downgrade to iOS 5. In the next few days, as the iOS 5.1 gets ready for a public release, if you upgrade to iOS 5.1, you can’t downgrade to any previous version till iOS 5.
Under this situation, if you save iOS 5.0.1 SHSH blob of iPhone/iPad, how is it going to be helpful? Sure you can use the iFaith software for quite a lot of other things like creating custom IPSW files – but would they come in handy ever?
Still, Worth taking the SHSH Blobs
With the hacking community, there’s no saying what the next thing would be. So, may be they’ll figure out some way of by-passing the APTicket method, and downgrading would be made possible. So it’s better to take SHSH Blobs of your iOS 5 and iOS 5.0.1 firmware.
