Developer iH8sn0w has released an updated version of the utility TinyUmbrella . The new version of an application designed to extract digital certificates SHSH blobs, has received a number of important improvements. In the next issue iH8sn0w promises to implement the ability to retrieve certificates for all versions of iOS.
TinyUmbrella - one of the oldest jailbreak tools. With it, you can save certificates SHSH blobs and BBTickets on Windows and OS X. Since then, as Apple has changed the algorithm authentication devices during the procedure downgrade and upgrade, the need for the program has disappeared. However, following the implementation of the program will again be relevant to users, says iH8sn0w.
The update TinyUmbrella 8.2 developer has added several new features and adjust the work program. Now, the utility determines the architecture of iTunes and warns if there can be problems with coordination. Also implemented the ability to determine the versions and identifiers SHSH. Improved function TSS Fetch, captures digital certificates, and improved user interface.
In the next update of the developer promises to implement the technology «on-device SHSH fetching»: TinyUmbrella will help save SHSH blobs for iPhone and iPad, even if Apple stopped signing the firmware.
Note that earlier presence SHSH blobs-recoverable operating system, regardless of whether Apple signs it or not. For example, if the iPhone is updated to firmware, for which there is no jailbreak (the same iOS 8.2), in the presence of a digital certificate from iOS 8.1.2 has the opportunity to roll back through TinyUmbrella.
In its current form until TinyUmbrella does not allow it, because it is a test version. This functionality will appear in her final release. But now with the utility iOS 8.1.2 users can retrieve the certificate to be able to further downgrade. For information on how to do this can be found on this page .
