Blur shader from test (SpriteBlur) doesn't work on iPhone 4

cocos2d-x C++
1

When i run on device it always shows error
// __IPHONE_4_0

 if(![context_ presentRenderbuffer:GL_RENDERBUFFER])
    {

// CCLOG(@“cocos2d: Failed to swap renderbuffer in %s\n”, FUNCTION);
}
On simulators it works perfect. I’m using cocos2dx 3.6 . So i’m really don’t understand what is it :frowning: Maybe someone know how to fix this…
