Compatibility with these devices cannot and will not be implemented.Ĭhanges to the Mac versions of ipsw and xpwntoolįixes missing libraries for idevicerestore through static linking on Macīelow follows a collection of questions answer by tihmstar.ĭo i need shsh blobs for downgrade with odysseusOTA?

The 2012 iPad 2 is not eligible, neither are the 3rd or 4th generation iPad, the iPhone 5 or the 5th generation iPod touch. The process will fail if the device has a baseband and the user forgets to pass the -bbupdate parameter when creating a custom IPSW.įour devices are eligible for OTA downgrading: The baseband is also flashed in the process. These are never validated after the restore is finished anyway. Since the boot loaders and ASR have been patched out of all integrity checks, the process will succeed even though the nonce, the root filesystem signature and some hashes would have failed validation.

The device is booted into kDFU mode using kloader and the restore process is initiated.

The request is accepted because Tatsu is unable to tell that the request does not come from a device that is being OTA updated.

SHSH blobs and an APTicket are requested.

All files are decrypted, iBEC, iBSS and ASR are patched, and the build manifest is modified by replacing UPDATE/ERASE hashes with corresponding OTA hashes. OdysseusOTA exploits this in three steps: Instead of forcing users to update through iTunes, Apple never stopped signing iOS 6.1.3 for OTA updates. All trademarks, registered trademarks, product names and company names or logos mentioned herein are the property of their respective owners.The 2011 devices, iPad 2 and iPhone 4S, cannot be OTA updated directly from iOS 5 to versions above iOS 6.1.3.

For those that we cannot downgrade yet, it still doesn't hurt to save what we can just in case. For those devices that still can downgrade this should work.

I'll update a fix as soon as I figure what I'm doing wrong. I've got something screwy with the request that is going wrong but I haven't figured it out yet.

TU has been updated for 7.1.x support but beware there are still some issues I'm working through for the iPhone 5S. This way, with TinyUmbrella you can restore the firmware of your device in a really simple manner. Thus, TinyUmbrella can also help in restoring your iPhone or other iOS device using a saved SHSH and by starting the TSS Server. TinyUmbrella is a useful application that was especially designed to provide users with a means of saving the SHSH blobs for their devices.
