Question about cust and firmaware

[GinnCorvus]

what do you mean by saiyng "that matches your firmware"? i have given a status of my phone of xs++ above...plz have a look and tell me an e.x.

The FS file and Custom pack file must have same language area (mediter, europa1, america1, chinese, etc...)

and smthg else: in xs++ which file of the cust pack we choose as customization? the whole file .zip?

Yes, you can use the embedded customization in the XS++ application: chose what you interest from drop menu. Or, if your missing, chose custom, create a "own_custpack" folder andextract here your custom pack file.
