No, I live in Poland. I know this method, but on metal plate which covers motherboard there is warranty sticker. I was worried about warranty but after this I decided to fix it myself. I hope your laptop will work fine after this as well mine.
BTW Banggood Custom Service replied me today after 3 days of waiting and said to record video about problem. Maybe they will help me somehow because Chuwi isn't gonna help us as we can see.
