[Warning] ipsw manual restore/update failure

Former Bender · 12-11-2007 06:50 AM

If you have downloaded an ipsw (iPhone-iTouch System Software) from a direct apple link and not from iTunes itself, do not unzip it and zip it back. It has the .ipsw extension, but in fact, it is a zip file

The problem is that the zipped back ipsw might be different (MD5,SHA1 or whatever) .
Then when you will manually restore/update in iTunes, it will fail.
I used several zipped back ipsw files and got failure every times and after used an original ipsw and the retore/update worked.

Mac users using Safari should disable the "Open Safe files after downloading" feature in Preferences>General as it will unzip this file automatically, so you will think you'll have to zip it back again.

All users: make sure the ipsw file you download is from Apple. If you download it from a website/torrent/ftp... you cannot guess if the guy who put it there did the unzip/zip manipulation.

I think many users, without knowing it, have faced restore/update issues because of this.

Well, for mac, just delete the unzipped folder and restore the IPSW file from the trash.

on windows, open a folder, go to tools, folder options, view, and then turn off hide file extensions for known file types

you will see if its saving as a zip or ipsw... more than likely its a ipsw on windows.
