Hi Trying to extract the OTA bundle get this error:

  From what i can tell some payload files do not have XZ data at the start like the rest, they have something before it (like another 
  file).

  In payload.002 It has two sets of XZ data with something else before hand.

  Also exists on many ATV OTA bundles just different payloads will error because of this.

  Example link to OTA: https://updates.cdn-apple.com/2020SummerSeed/patches/061-92077/73A5B815-38F1-4474-812D-F24E5A88575C/com_apple_MobileAsset_SoftwareUpdate/8988ef3518b1f20f95c66d03be3c15eb4e1be2a0.zip

So what we are trying to do is create an Apple TV 4K IPSW for restoring, which we have already done successfully allowing upgrade and downgrade, with the right hardware and tools.

This would allow us to release a method without shipping an IPSW

Hello, I just need this file because my appletv4k is broken and needs to be restored. Have you made this ipws file? Can you share it with me? Thank you.

If you message me on Reddit I can help you out. /u/Spxrk

hello! there is currently no way for ipsw to generate an IPSW from an OTA. That is an interesting problem, but I currently have no use for it myself and therefore cannot prioritize it, however, I'll leave the issue open as a feature request so that it might be placed on the RoadMap at some point
