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)

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

• On unc0ver, install libkrw.

Converting mkv to mp4 with ffmpeg

Essentially just copy the existing video and audio stream as is into a new container, no funny business!

The easiest way to "convert" MKV to MP4, is to copy the existing video and audio streams and place them into a new container. This avoids any encoding task and hence no quality will be lost, it is also a fairly quick process and requires very little CPU power. The main factor is disk read/write speed.

With ffmpeg this can be achieved with -c copy. Older examples may use -vcodec copy -acodec copy which does the same thing.

These examples assume ffmpeg is in your PATH. If not just substitute with the full path to your ffmpeg binary.
