- Downgrader script by LukeZGD -
Usage: ./restore.sh [Options]
NOTE: CLI implementation is NOT COMPLETE (yet)
List of options:
--debug For script debugging (set -x and debug mode)
--device-ecid [ECID] Provide device ECID (must be decimal)
--device-type [Type] Provide device type (eg. iPad2,1)
--entry-device Enable manual device and ECID entry
--help Display this help message
--no-color Disable colors for script output
--no-device Enable no device mode
--no-version-check Disable script version checking
For 32-bit devices:
--kdfu Place device in kDFU mode
For devices compatible with downgrades (see README):
--custom-ipsw [version] Create custom IPSW for provided iOS version
--downgrade [version] Downgrade/Restore to provided iOS version
--ipsw [IPSW path] Set path to IPSW
--ipsw-verbose Enable verbose boot option (iPhone 4 only)
--jailbreak Enable jailbreak option
--memory Enable memory option for creating IPSW
--save-blobs [version] Save OTA blobs for provided iOS version
--shsh [SHSH path] Set path to SHSH
* For jailbreak option on 8.4.1, also provide [jailbreak] (etasonjb | daibutsu)
* For "Other" downgrades with SHSH, provide "Other" without quotes as version
* Default IPSW path: <script location>/name_of_ipswfile.ipsw
* Default SHSH path: <script location>/saved/shsh/name_of_blobfile.shsh(2)
