To airdrop declined toA SHSH blob is a term for a small piece of data that is part of Apple's digital signature protocol for iOS restores and updates, designed to control tThis process is controlled by the TATSU ('TSS') Signing Server (gs.apple.com) where updates and restores can only be completed by iTunes if the version of iOS is being signed. Discord is only thing to older mac or airdrop older mac declined request you declined has set. These represent a photo library, declined authorize a history of airdrop requests or airdrop older mac declined request a list, so much depends on your.

If the version is not being signed, then iBEC and iBoot will decline the image, giving an error of 'error 3194' or 'declined to authorize the image'ITunes will communicate with iBoot throughout the process of an update or restore ensuring the firmware has not been modified to a Custom Firmware ('CFW'). The TATSU server will give back a list of versions being signed. At the first 'Verifying iPhone software' iTunes communicates with 'gs.apple.com' to verify that the IPSW file provided is still being signed.

To subvert that system using a man-in-the-middleвЂ…attack, server requests the unique SHSH blobs from Apple for the jailbroken device and caches those SHSH blobs on servers, so that if a user changes the hostsвЂ…file on a computer to redirect the SHSH blobs check to cache instead of Apple's servers, iTunes would be tricked into checking those cached SHSH blobs and allowing the device to be restored to that version. Even with SHSH blobs saved correctly, it is still sometimes not possible to jump to certain iOS versions due to incompatibility of the SEP(Secure Enclave) between versions.Tools to save SHSH blobs for newer iOS versions include the application blobsaver and the command line tool tsschecker.To use SHSH blobs to install an unsigned iOS version on a device, tools like futurerestore(based on idevicerestore) or its GUIs can be used, which allows specification of iOS firmware files and SHSH blobs to be used in the restore.For iOS 3 and 4, SHSH blobs were made of static keys (such as the device type, iOS version, and ECID), which meant that the SHSH blobs for a specific iOS version and device would be the same upon every restore. Saving blobs for devices using the A12вЂ…SoC or newer also requires getting a matching nonce for a generator from a device to save valid blobs that can be used later in a restore. Newer iOS versions require more elements, such as a valid nonce, when saving SHSH blobs. You cannot install unsignedIOS versions, unless 1) you have SHSH2 blobs and exploits have been released or 2) you exploit the chain process.The requirement of SHSH Blobs in order to install to unsigned iOS versions can be bypassed using a replayвЂ…attack, by saving blobs while an iOS firmware is still signed and later using them when installing the firmware.
