The iOS firmware SHSH backup tool TinyUmbrella has been updated to version 6.10.03a, providing SHSH backup support for the iOS 6.1.1 firmware of iPhone 4S.
The advantage of backing up SHSH is that you can re-flash the old firmware in the future. Little Umbrella supports iOS 6.1 backup for all iOS devices, so jailbroken users who have not yet backed up should hurry up, because Apple will soon launch iOS 6.1.2 to fix bugs. Once the new firmware is released, 6.1 will soon turn off verification.
After the iPhone 4S upgraded to iOS 6.1, it was found that there was a problem with the 3G network connection. In order to solve this problem, Apple urgently released an iOS 6.1.1 update for iPhone 4S users. Fortunately, this update does not block the jailbreak vulnerability of iOS 6, so iPhone 4S users can still experience the perfect jailbreak of iOS 6.1.1. Because iOS 6.1 has a series of problems, Apple will continue to update the firmware until the problems are solved.
It is said that it is not easy to downgrade now, but it is always a good thing to keep the SHSH blobs with the old version of the firmware, which is why the little umbrella is always updated.
