HI All

May be someone can help me,i got a samsung note 3 SM-N9005 (LTE) model and it stopped working one week back. It completely went dead and wont start now. Tried showing it to Samsung Service Center, however they cant support as LTE model is not launched in India. As per them the motherboard is an issue. This was a gift from my sister and she had baught this in Dubai. Please advise how can i bring it back to life or if someone can help me with a motherboard for SM-N9005 model.
