notcom a.k.a semaphore has released a new version of TinyUmbrella (5.11.01) to add support for the revised iOS 5.1.1 (9B208), that was quietly released for GSM iPhone 4 users yesterday.
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.
Initially, 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 few days back 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.
Chronic Dev team had also released Absinthe 2.0.2 to add support for revised iOS 5.1.1 (9B208).
Let us know how it goes.
