This will create an IPSW that only flashes your device's NOR. It will not touch the operating system or NAND.
- Create a custom IPSW
- Unpack it, remove rootfs DMG
- Decrypt the ramdisk (xpwntool) and mount it.
- Edit options.plist (/usr/local/share/restore/options.plist) on the restore ramdisk:
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>CreateFilesystemPartitions</key> <false/> <key>UpdateBaseband</key> <false/> <key>SystemImage</key> <false/> </dict> </plist>
- Unmount and reencrypt the restore ramdisk.
- Repack the IPSW.
NOTE: This technique only works on devices that have an untethered bootrom exploit (Pwnage or 0x24000 Segment Overflow).
