I'm sorry but it didn't work I already do that when my phone start like that. I even go to repair shop he said that it can fix but it works for a while but it turn back again. And when he fix my phone was its like I'm baying new phone again because he need to change the whole phone. So he suggest that I just buy new phone. And I accidentally reset my phone without thinking properly because I'm super stress about my phone issue. Thanks for realizing me to give up already it's no way that there's a way to fix it. Also thank you for your concern and suggestions I appreciate it.
