notcom a.k.a semaphore has released a new version of TinyUmbrella (5.11.00b) that allows iPhone, iPad and iPod touch users to save SHSH blobs for iOS 5.1.1, that was released by Apple earlier in the week.
TinyUmbrella allows you to take backups of SHSH blobs (ECID SHSH) that can be used to downgrade to older iOS versions even after Apple stops signing the iOS firmware file. It can come in handy if you end up accidentally upgrading to the latest version of iOS.
Until yesterday, it was possible to downgrade only iPhone 3GS, iPhone 4, iPad 1, iPod touch 4G and iPod touch 3G from iOS 5.1 to iOS 5.0.1 using the SHSH blobs saved using TinyUmbrella. But iPhone Dev team released a new version of Redns0w yesterday that also allows users to downgrade their iPhone 4S, iPad 2 and iPad 3.
It’s very simple to save SHSH blobs. All you need to do is follow these steps:
- Update: Download the latest version of TinyUmbrella from here
- Connect your iOS device to the computer
- Install and then launch the latest version of TinyUmbrella (ensure it says v5.11.00 in the title)
- Select your iOS device from the “Connected Devices” list
- Then click on the “Save SHSH” button.
After the SHSH blobs are successfully saved, you should see your iOS device listed along with the iOS version that it is running on currently under the General section, which says Saved SHSHs.
Please note that your iOS device doesn’t need to be on iOS 5.1.1 to save SHSH blobs for iOS 5.1.1, so don’t waste any time and save the SHSH blobs for iOS 5.1.1. It also looks like Apple is still signing iOS 5.1 so you will be able to save SHSH blobs for iOS 5.1 as well, in case you haven’t save them already.
