14.8.1 IPSW Creator

There are premade IPSWs available for download

Funny little script to make a 14.8.1 IPSW, used for pwned restores. May or may not work. Use at your own risk.

Created by Nebula and Nick Chan, with help from galaxy#0007.

Requirements

• macOS
• From Procursus: aria2, ldid, 7z
  • Easiest way is to Procursus strap your Mac, then sudo apt install aria2 ldid p7zip
• asr64_patcher
• restored_external64_patcher
• trustcache
• img4lib

Binaries should be in path, easiest place is /usr/local/bin.

Usage

./makeipsw.sh <link to 14.8.1 ota> <deviceid, eg. iPhone10,6>

It's pretty easy. Output IPSW will be in the ipsws folder.

Restoring

Requirements

• Latest futurerestore action build
• 14.8.1 OTA blob
