Restoring to 27.1

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

Required Reading

iOS 27.2 was recently released, patching several bugs that could potentially lead to a jailbreak.

Luckily, iOS 27.1 is still signed, meaning you can restore to it from any other iOS version with the help of iTunes or Finder.

DANGER

iOS 27.1 will be unsigned in the future (likely during the week of November 2nd-6th). As a result, if you are considering restoring back to iOS 27.1, you should consider doing so sooner rather than later.

WARNING

iOS 27.1 was only released for the iPhone Duo, and was not released for any other device.

If you are not using an iPhone Duo, you should instead follow either:

• Restoring to 27.0.1 if you are using an iPad that supports iPadOS 27 or a different iPhone
• Restoring to 26.7.1 if you are using an iPad that *does not* support iPadOS 27

Downloads

• The iOS 27.1 .ipsw file for the iPhone Duo

Restoring to 27.1

WARNING

Assuming you are currently on iOS 27.2, you will likely need to enter Recovery Mode or DFU Mode in order to proceed.

1. Plug your device into your computer.
2. On iTunes or Finder, locate your device.
3. While holding down the Shift (Windows) or Option (Mac) key, click Restore iPhone.
4. Locate the .ipsw file you downloaded, and select that .ipsw file.
   • Ensure that the version you are updating to is iOS 27.1 (24A94425)
