I do not need to someone to prove something.  
First of all do it for myself, because I'm interested.   
All the results in the gallery http://vk.com/album221982133_210576386 
In 5.2.5. no Russian language, especially in such interpretation. 
The result is a custom firmware repacked with the Russian language. 
The code was completely different and it was interesting    
  
did you counter the issue: 5.2.5 chinese region camera change to english language , it will restart again and again  with a short time?
