I tried to flash android on my onda v919 air dual os with the method that onda gives us. I have deleted both Android and windows.
As mentionned, I put the firmware on an USB stick and boot on “built in uefi” then the shell lauches and tries to boot on droidboot but that totally fail because the shell is only 32 bits whereas the image is 64bits ( ???).
I tried to boot directly in recovery by pressing power and vol-, the tablet finally boots on Droidboot but once again the flas fails ( picture ) but I can send fastboot commands to flash manually but once again, it’s a fail.
