I found some really nice Jaku icons and when I used iExplorer to look for the icon folders all I see in them is a file called icon2x.png. How to I replace an icon with another image within a theme?
You need to find the folder of the icon you want to replace.
For example if you want to change the Safari icon then look in the Bundles folder for com.apple.mobilesafari folder and replace/overwrite the icon inside with the new icon.
It has to have the same name though so either change the name of the original icon (i normally add another x after the 2) or just overwrite it if you dont want it anymore.
So, if it's just one then that'll be the icon that is being used at present. Name the new icon the same as the present one and drop it in the folder and it'll overwrite it.
Again if you want to keep it then rename it first.
So if I checked the icon sets of a theme that wasnt in use they would have actual names not just icon2x.png?
I just replaced about 6 icons under the Jaku theme. All but the photo icons were named icon2x.png. I renamed the old ones to oldicon2x.png. Restarted and no change.
