Other notes:

  • You do NOT need blobs to use this, the script will get them for you
  • To devices with baseband, this script will restore your device with the latest baseband
  • This script has a workaround for the activation error on devices downgrading from iOS 10
  • This script uses futurerestore "Odysseus method" for downgrading (different from OdysseusOTA/2, which are deprecated)
  • This script does not modify the IPSW and will verify it with SHA1sum before restoring
  • This script only uses iBSS patches for entering kDFU mode
  • This script can also be used to just enter kDFU mode for all supported devices
  • This script can also be used to futurerestore to other iOS versions with provided SHSH blobs
  • This script can also work on virtual machines, but I won't provide support for them
