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?
