The most reliable current methods involve using automated tools or online services. Blobsaver (Desktop App)
The server refuses to send the blob, and the restore fails.
Here's the structure: * devices. - : output of ideviceinfo. * shsh-blobs. blobsaver.xml : exported blobsaver config. - blob files. SHSH - The Apple Wiki shsh host
