Default International Languages Issue

Dears,

I have changed the "Country" to "cn" and then I have flashed the Huawei U9510E B611 Official ROM and after that I faced a problem in languages as there's no "Arabic Language" at all, so how I can get back the "International Languages" ?!!

Hence, the available languages are "English & Chinese".

Please, I need an urgent help, and I will be grateful to you.

Thanks.
