I have an iPhone 5 that I use with Straight Talk (telecom provider) and I am trying to "upgrade" it from 7.0.4 to 7.1.2, or any release with the 7.x version for that matter.
I specifically do not want to upgrade to IOS 8 just yet.
I have the file "iPhone5,2_7.1.2_11D257_Restore.ipsw" but I get the error "The device isn't eligible for the requested build." I've also hashed out the gs.apple address in my hosts file.
I know you can't downgrade from 8 to 7, but in this case is there a way I can still upgrade to a later version of 7.x?
