Balong Bug Marsmallow?

I upgraded to Marshmallow B564 everything is fine, but the model number says "hi6210sft" instead of Ale-L21 in this version. The build is OK, I read something about that name and the balongbug. How can I fix it?
I have Ale-l23 converted to Ale-l21 and I make upgrade from B170 and B188 with no Balong bug. The problem is in this build.
I'm newbie, I can't post links or images :(
