I just noticed I never left an update on my RMA status. After 3 weeks of examining the issue they did shipped a new tablet to me. Delivery took about 1,5 months 🙁
To whoever has the same issue I suggest you to get in contact with the seller you got it from and arrange a replacement of your unit. It might cost much you to ship it back to China if you’re outside Asia, and will surely take few long months to get a working unit back, but according to my experience that’s the only option.
