I understand that Macbook Air 2011 and Mac Mini 2011 uses a pre-installed OS X Lion with a different build number (11A2063).
However, it seems that with 10.7.2 , there is only 1 build number: 11C74 , as per http://support.apple.com/kb/HT1633 , does it mean that 10.7.2 is a unified version of the OS X Lion for all mac products?
Therefore, would it be possible to purchase & download the Lion Installer from Mac App Store , extract the InstallESD.dmg and use it as a offline Lion installer for Macbook Air 2011 / Mac mini 2011?
P.S. I am seeking an offline solution because the recovery partition has been damaged, the internet recovery doesn't work (error 3403F & 4403F), and the recovery disk I have created with http://support.apple.com/kb/dl1433 showed an error "could not find installation information for this machine". And the Apple Authorized Service Providers are charging $150 for a simple restoration of the recovery partition.
