I've recently downloaded .ipsw file (firmware 7.0.6) and want to update my apple 4s 32 gig phone (ios 5).
but when I tried to to use iTunes (holding shift key in windows 7 + press update button in iTunes -> choose .ipsw file for update) I got the error below :
http://support.apple.com/kb/TS4451
What does this error mean and how can I fix it?
I've downloded iTunes 11.2 (latest version)
Extra questions:
I am certainly sure there is no problem about my internet or hosts file.
I turned my anti virus & firewall off and after that still got that error.
Is it possible to transfer .ipsw file to my phone and run it from there?
If yes, where should I copy that file and how can I run it?
If no what is the solution and how can i fix that error?
