I need to downgrade my iPhone 4 from iOS 7 to iOS 6.1.3/6.1.2
Since I don't have SHSH blob for iOS 6.1.3/6.1.2, if you can get me that it'll be great. You can do that by following this link.
Follow this video by iPhone Hacks:
NOTE: You should be having an iPhone 4 running iOS 6.1.3/6.1.2 only! Anyone there, help me!
If you have already saved the file (SHSH blob for 6.1.3/6.1.2) then please revert!
