Yes, I tried this, but have no results(screen continue off).
You told the red led should turns on at 3 seconds but it never happened on the tablet.
I tried also make a full system recovery as stated in Hi10 Go drivers - #17 by iuwu871.
But even if I have success, it would continue black screen cause, as stated in major cases here on forum. the black screen have todo with bios.
Thank you for assistance.
