Chuwi has corrected the problem.

Confirmed that some HI-12, Hi-10 and HiBook users are reporting dead , bricked devices after Windows driver updates.  

Until there is a solution or confirmation from Chuwi that this is no longer a problem, It is necessary that everyone disable automatic driver updates in Windows 10 and definitely do not use Windows device manger to update drivers in the "firmware" section. Drivers in this section modify secure boot code.

Read this for the method to do this. Its quite easy.   
NOTE: This is not the same as postponing Windows Updates,  I don't recommend stopping all windows updates, just drivers. And you won't see addtional 3 options in Windows 10, its just Yes or NO

I mentioned this problem in a posting I made about my H12 unit and a booting problem and Emily the moderator stated the problem is resolved as to the driver updating issue and bricking.See below:

Hello,

The automatic driver updates issue has been solved, it is safe.
When you see Android/Windows icon, you can press Volume Up/Down key to choose Android/Windows.
Does anyone know if this is truly the case and a definitive resolution to the driver updating causing bricking issue is over?
Thanks

The coast is clear as long as no one from Teclast or Chuwi releases another bum BIOS...  I'm running my second Windows 10 Insider preview build here since the other problem was bricking things -no problems.  Honestly, considering all the care all manufacturers took in past to warn people about bricking motherboards on BIOS updates, you'd think Microsoft would have made you take an additional step and definitely OK any BIOS updates before trying to apply them.  Yeah, Microsloth,  I'm pointing at you too.  I mean a driver update gone wrong can be a pain, but BIOS gone wrong is usually a much harder problem to solve, especially without the right equipment/knowledge.  I've burnt Eproms since they had mica windows and required UV to erase them and I don't just happen to have the proper equipment lying around.

It's possible, I do not have a HiBook, but I'm sure they share some drivers and circuitry . Have you seen similar reports from HiBook Users?

Looks like there is a bricked dead Hi-12 solution tutorial by Bill Christiansen and it  looks great I would only add one thing, if you cut away any of the thermal pad to get to the chip, save it and put it back on after you finish. That pad keeps the CPU cool and its pretty important.

This requires you purchase some hardware (about $25) and open your device to accomplish the procedure.

The EPROM programmer used in the fix is available at Amazon for about $11 US.

You will also need one of these Chip Clips available as Amazon  for about $11 US

And one of these which curiously I could only find on Ebay from China at about $5 US

This is now the confirmed way to fix bricked tablets.  You must use the external hardware programmer.
All of you that still have working Hi-12, Hi-12 and Hi-Book, make sure you have disabled automatic driver updates by the method I posted above from

Looks like I have the same problem with my chuwi hi10. Suddenly died/brickek and would not start again. And I could not try the solutions given because I could not buy equipment eeprom because it can not be shipped to my country. So is there any other solution ? I bought it two months ago and suddenly died three days ago.

Hi,
The problem of the Telcast Firmware System has been solved. Your tablet suddenly died and would not start again, please charge it for 2 hours and press power button three times continuously then long press for 15 seconds.
