Che cos'è un file SHSH2?
An SHSH2 file is a digital signature used to authenticate iOS firmware. It contains data that Apple's servers use to verify that a user is installing an approved version of iOS. Primarily, SHSH2 files prevent users from downgrading their firmware.
Maggiori informazioni
When you install a new version of iOS on your iPhone, iPad, or other iOS device, your device generates an SHSH2 file. Apple's servers read this SHSH2 file, which is sent as a digital signature, to verify that the version of iOS you are installing is current, and therefore allowed to be installed.
Most iOS users will never actually encounter an SHSH2 file. However, those who want to revert to a previous, unsigned version of iOS (likely to jailbreak their device) will need to manually generate an SHSH2 file. Websites such as TSS Saver and SHSH Host allow users to save and generate SHSH2 files, using their device's ECID and model identifier.
NOTA: iOS digital signatures may also be saved as .SHSH files.
Come aprire un file SHSH2
SHSH2 files are not meant to be opened. Those looking to downgrade to a previous version of iOS can use jailbreaking tools such as iFaith (Windows), 3uTools (Windows), and futurerestore (cross-platform) to use an SHSH2 file to install a previous version of iOS.
