Impossible to flash android on ONDA V919 AIR 32GB z3537 v9

Hi all,

For few days i'm trying to update/flash android on my onda v919 Air V9 dual OS and it getting worse and worse.
1) First I tried update the android system and extend the internal storage for android with partition.tbl and I got this message "please enter password to decrypt storage".
2)And I had no working android and windows system. So I flashed Windows 10 32bit from usb pendrive( downloaded with MediaCreationTool).
Win 10 was working without drivers (no touch, sound ...).
3) So I tried install android again and I killed both system.
4)I tried install windows 32/64bit again and not working (acpi bios error or 0xc0000359)
And the OS switch is not working.

How can I get working system again?
Any idea/help?
