Install iOS 7 – How to extract the ipsw from dmg file
iOS 7 is out. I need to give it a try, even though some people say you shouldn’t mainly because it is beta as this post from cult of mac says –> http://www.cultofmac.com/231392/why-you-probably-shouldnt-install-ios-7-right-now-opinion/
In any case this guy says you can downgrade: http://www.idownloadblog.com/2013/06/11/how-to-downgrade-ios-7-to-ios-6-1-3/
But let’s cut to the chase. I downloaded the software from developer.apple.com – you need a dev account for that. And so I have the dmg file in desktop. I go to iTunes now and it doesn’t let me select the dmg file. Crap I forgot that #1 the ipsw is inside the dmg file, #2 my Mac Book Pro is at work and #3 I don’t want to wait for tomorrow as I only have Windows on this side of the city.
Download Power Iso (http://www.poweriso.com/) and open the dmg file. The dmg file is just like a zip file in logical terms, extract the ipsw and install from iTunes.
Voila! iOS 7 installed and I am ready to suffer bugs, bad battery life and everything that comes with a beta!
