Updating (Blobless) (Advanced)

For support in English, ask for help on the r/Jailbreak Discord Server.

Required Reading

iOS and iPadOS devices can typically only update to firmware versions which Apple has "signed". This usually means that you can only update to the most recent firmware versions. This is bad for jailbreaking, as most jailbreaks rely on exploits that have been patched in newer versions.

Fortunately, we can use different "profiles" to delay a firmware update. This is intended for organisations which require additional time to update their devices, however we can also use these to update to unsigned firmware versions.

This has a time limit, however. You will only be able to update to the following firmware versions before their respective expiration dates:

  • 12.5.6 (Only for devices which did not receive iOS 13 or newer) - November 29th, 2022
  • 15.5 - October 18th, 2022
  • 15.6 - November 15th, 2022
  • 15.6.1 - December 11th, 2022
  • 16.0 (iPhone 14 series only) - December 13th, 2022
  • 16.0 (All other devices) - December 21st, 2022
  • 16.0.1 - December 21st, 2022

Time is given in UTC 00:00. For more expiration dates, view dhinakg.github.io/delayed-otas.htmlOpen in new window.

Because you do not currently have a jailbreak (or you choose not to jailbreak for any reason), you'll have to use advanced methods, involving things such as resetting all contents and settings, to be able to update.


Depending on your target iOS version, you won't be able to do this if you futurerestored after the following dates:

  • 12.5.6: August 31st, 2022
  • 15.5: July 20th, 2022
  • 15.6: August 17th, 2022
  • 15.6.1: September 12th, 2022
  • 16.0 (iPhone 14 series only): September 14th, 2022
  • 16.0 (All other devices): September 22nd, 2022
  • 16.0.1: September 22nd, 2022
