Is any chance to change Android System Language on US Version Phone

[DmitriiMaster]

The factory unlocked US version android phone with snapdragon qualcomm chipset was purchased in USA. I am not able to change the android system menu from English language to Russian language. The MoreLocale 2 program was not assisted too much ( the some of apps names were change to required language only ).
I need a help on how to change the system menu to Russian or confirmation that this can't be done on this version of phone.

Best place to get an answer to that kind of question is for you to go to xdadevelopers website.

What happens when you try the "Add a language" button? This should allow you to add Russian.
