DsF, you made a basic beginner's mistake. Folder name - iGO_Israel(Luna)
Each topic about a specific edition lists the allowed names. That's the name that the apk reads, not where the content is
datafoldername - the name alone tells you

Unfortunately, our Forum Luna topic has long been lost. The only name allowed is iGO_Luna
It is possible to change it, you just need "a little" of programming knowledge
