What's nonce entanglement?

Beginning with devices using an A12 SoC or higher, Apple introduced nonce entangling.

This meant that, when saving SHSH blobs, a nonce generator would generate a different ApNonce for each device.
When saving SHSH blobs for an A12+ device, you now must find a generator-ApNonce pair for your device, then use that generator-ApNonce pair when saving SHSH blobs.
After you have found a generator-ApNonce pair for your device, you can save it and re-use it whenever you save SHSH blobs again.

Getting a generator-ApNonce pair (jailbroken)

(iOS 14+ only) Install an iOS kernel r/w library.
- On Taurine, install libkernrw.

On unc0ver, install libkrw.

Downgrade and dualboot status of almost all iOS devices

As of updating this post, there is a downgrade tool that utilizes a SEP exploit released. However its device support is currently limited: https://limefix.tech/?product=limefix-sep-utility-testing
- There might be a better downgrade tool that uses a SEP exploit in the future, it may be better to wait for that instead
Save SHSH blobs for signed iOS versions using TSS Saver or blobsaver

Exporting your 2FA tokens from Authy to transfer them into another 2FA application

IMPORTANT - Update regarding deprecation of Authy desktop apps

Past August 2024, Authy stopped supported the desktop version of their apps:
See Authy is shutting down its desktop app | The 2FA app Authy will only be available on Android and iOS starting in August for details.

And indeed, after a while, Authy changed something in their backend which now prevents the old desktop app from logging in. If you are already logged in, then you are in luck, and you can follow the instructions below to export your tokens.

If you are not logged in anymore, but can find a backup of the necessary files, then restore those files, and re-install Authy 2.2.3 following the instructions below, and it should work as expected.
