Chuwi Hi9 Plus 2-in-1 Android 8.0 does not start

Hello … before throwing it away I wonder whether there is a magic trick to revive my Hi9 Plus tablet. It worked well for 3 weeks but suddenly refused to start up - the screen remains black. Pressing the power on button for a long time slightly enlightens the screen for a couple of seconds before becoming pure black again. That’s all life which is still in this tablet. Because I missed the 1-month complain deadline by 3 days support wants me to send it to Hongkong.

Please contact

I have the same problem. It worked well for 5 moths, but now following restart screen remained black, no logo, nothing after 15 sec pressing on button. What to do? I contacted aftersale… but there insn’t new idea.
