How to install iOS 15.8.1 from the IPSW

Four steps, and the one that matters most is the first.

Back up first

A restore erases the device. Make an archived backup in Finder or the Apple Devices app — an iCloud backup taken on a newer version cannot be restored onto an older one. Our backup guide covers the difference.

Get the file for your exact model

Check Settings → General → About → Model Name, then download the IPSW for that device. The download shows the file size; compare it with the SHA-256 under Details if you want to be certain the file is intact.

Restore in Finder or Apple Devices

Connect with a cable, select the device, then hold Option (Mac) or Shift (Windows) and click Restore to choose the .ipsw. Update keeps your data but only works upward; Restore erases and is how you downgrade.

Set up or restore your backup

After the restore the device starts fresh. Restore the backup you made — only if it came from the same or an older version than the one you just installed.

Questions? Answers.

Can I restore iOS 15.8.1 today?

Not at the moment — Apple has stopped signing 19H380, so a restore will be rejected at the final step. The files remain here for reference and for signed re-releases.

Which is the right file for my device?

Match the identifier in Settings → General → About (or under the model's name here) against the one on each row. Wi-Fi and Cellular iPads share a file; different generations never do. Restoring the wrong device's IPSW simply fails — it cannot damage the device.

What does "signed" mean?

Apple's servers must approve a firmware before a device will accept it, and Apple only approves the builds it is currently shipping. A signed file can be restored today; an unsigned one is rejected at the end of the process, however you obtained it. Signing status changes without notice, usually within days of a newer release, which is why this catalogue rechecks it automatically.

Will I lose my data?

A Restore erases the device — that is what makes a downgrade possible. An Update with an IPSW keeps your data, but only when moving to a newer version. Either way, make an archived backup on a computer first; an iCloud backup taken on a newer version will not restore onto an older one.
