tvOS 17 IPSW Downloads

Not any more. Apple has stopped signing every tvOS 17 build, so a restore to any of them is rejected at the final step, whatever file you use. The files are listed for reference — and because a device's signing window can reopen briefly when Apple re-signs an older build.

Only to a build Apple is signing, and only by erasing: a recovery-mode restore in Finder, the Apple Devices app or iTunes with the IPSW for your exact model. A backup made on a newer version will not restore onto tvOS 17, so the backup you need is one taken before you upgraded. Our downgrade guide walks through it.

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.

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.
