Unsigned Ipsw File Without Shshs Code Coming From

Guys please note that this method to How To Downgrade iOS unsigned ipsw 14.4 to 14.3 is safe but please follow all the steps with care.

This is basically an in-depth tutorial on how to use FutureRestore with previously saved SHSH2 blobs and a NonceSetter.

Using this tutorial you can restore to an unsigned iOS version as long as you have the saved SHSH2 blob, you are on an exploitable jailbroken version, and the SEP and Baseband are compatible.

As the OS itself, the baseband gets updated and could be downgraded or upgraded just to signed baseband versions.

Some of you may know what futurerestore is, but Ill explain that anyway.

There are lots of variables, so Ill try not to enter into details, but also try to explain it as clear as possible.

Of course there is much more, but for now well stick with these.

The firmwares packages are usually.zip or.img for Android and.ipsw for iOS.

They way they get installed is completely different, though.

If youre wondering what it is, the kernel is (as the name suggests) the core of the entire OS, with complete control over everything in the system and even responsible of the interfacing between the various hardware components, such as the translation of the IO requests to data-processing instructions for the Central Processing Unit.

In some form or another, it is present in every smartphone, but usually it is on Android ones.

It could also have a different name, but what it does is basically allowing the user to install, update, backup or restore several crucial SW components of your device, such as firmwares (compressed in images or uncompressed), OTA updates or even kernel, basebands or recoveries themselves, sometimes also providing debugging support as well as basic file manager functions with rw access to the root filesystem.

The recovery is a very powerful tool, thats why not every OEM allows users to have access to all of its functions, or not even including some of them at all.

Basically, stock recoveries usually allow users to install at least OTA updates, but all the aforementioned as very rare to find on stock recoveries.

Thats why the Android scene offers several powerful open-source alternatives such as the Team Win Recovery Project, aka TWRP.

Even iOS has a recovery mode alongside another mode called DFU: the first one allows you to perform a factory reset updating your iDevice to the latest iOS version available, the second one (which stands for Device Firmware Update ) skips the iBoot bootloader and so permit in some specific cases to downgrade.

Anyway, theyre both very limited and dont allow the user to perform any action: it just works as an interface between the iPhone and the PC.

So why dont install a custom recovery and get away with it Dont overhype, thats not that simple.

The problem is indeed at the root, most of the times the bootloader is closed, and does not allow the user to load anything else then what it is meant to load.

Sometimes you can unlock the bootloader (even though most of the times that require unique code coming from the OEM, but requesting it implies losing your warranty).

But a lot of brands also chose not to provide any way to unlock it at all.

So basically there is no way to load unauthorised software, and Apple even puts a step forward to it.

Not only you cannot run unauthorised software, you also cannot even run any form of unsigned OS.

Apple, anyway, temporary signs its iOS version for a limited period of time, that means that once Apple it stops to sign a specific iOS version (usually one or two weeks following the release of the subsequent iOS version), there is no official (and sometimes even unofficial) way to downgrade to it.

They are generated from the device bootloaders (baseband, firmware and SEP OS) at the time of a restore request, but are issued just when the iOS version youre currently trying to restore to is still signed.

There is also another way to save them though: you can use a script in order to ask for a valid SHSH blob without performing a restore.

That would allow you to store a copy of a signed blob which remains signed, and so it can be used later to perform a replay attack within futurerestore or one of its wrappers.

The baseband is the firmware running on the cellular modem hardware.
