Can TinyUmbrella download all the SHSH blobs for a device?
The tool will download the SHSH blobs only for the firmware that is still being signed by Apple. For example, if you’re on iOS 10 and Apple has stopped signing it, TinyUmbrella will not download blobs for that version. All the blobs get saved in one single file at ~/.tu/.shsh.
