“This is what works:
Hold the power button down for 14 seconds. Leave the tablet, plug it in overnight to charge.
In the morning hold the power button for 3 seconds and then keep tapping it again a few times it should power on. If it fails to power on use another power adapter. Let me know if it works. It has for everyone I’ve told so far, apart from some Chuwi Hi8 Pro owners including myself.”
Thanks man, it really worked!
