I couldn't uninstall iCosta from my installer.

It shows up a blue box indicating "main script execution failed" when I was trying to uninstall.

Can anyone help me out in this issue?

It makes me soo furious =(

Thankz.

This is because you have installed 2 different versions and uninstalled one.

Because Installer can't find the files to delete, it says this "main script execution failed".

You have to manually remove the iCosta section in

Code:

/private/var/root/Library/Installer/LocalPackages.plist

You must remove this (don't mind if the version is not the same).

but I just only install one ~

So am I going to uninstall it via ibrickr?

Is there any other ways to uninstall it just using iphone?

I've deleted the 1st code

But where to find the 2nd code which you mentioned above?

I can delete the 1st one using mobile finder =)

Right?

You must edit LocalPackages.plist, not delete it.

The 2nd quote is the piece of code you have to remove inside LocalPackages.plist
