Full restore CHUWI HI10 CW1526

Yesterday while updating Windows 10 the update failed and the system tried to cancel the changes, but the Chuwi wouldn’t restart and even a full Windows reset wouldn’t work. The computer won’t start either on Win 10 or Android.
My Chuwi Hi10 is labeled model CW1526 and the serial number is HiB PQ64G45160601389
It is no longer under guarantee
Where can I get the firmware (working link) and a tutorial on how to reflash?

Thanks for your urgent help
