I have my blobs saved from 6.1.2 and I have to restore my phone and I want to know how to use the blobs I saved w iSH to restore it? Any help would be greatly appreciated.
As time goes on, it's possible they will be useful. As of right now, there isn't any way they've found to use them to downgrade the 4s.
But, it was good you saved them. It's better to save them and be sad you can't use them than not save them and be sad there's a way you missed out on later.
