Are the devices identical hardware-wise? As first step, extract boot paritition from stock firmware. Try to repack it and make sure it can be booted (flash or boot directly via fastboot). Then try replacing kernel with the one found on Dell Venue 8 7840 Android 5.0 firmware and check if it still can boot (kernel modules won't match, but display driver is usually built into kernel).
i don't know if they are identical. thanks for the ideas. why do i need the new kernel? for drivers? btw i broke ground on USB ,so ibrought it to arepair shop

will the 6MB "kernel" file i extracted from boot.img do?

or can sb send me the contents of the boot partition?^^ it doesn't hurry though, because the tablet is still at the repair shop :D

You don't need boot partition. The kernel from /boot folder in rootfs is loaded using GRUB. We can't use Android bootloader, since UEFI is 32-bit and Jolla Tablet has 64-bit kernel (it's possible to compile 32-bit one, but I had some PulseAudio-related system crashes).

so i just have to copy the files to a partition and install grub with reference reference to the kernel

Exactly, no special installation is needed for GRUB, copying files to EFI partition is enough. If you want, I can try to make image for fastboot to flash Sailfish OS on ONDA.

Well, no luck with fastboot so far due to droidboot limitations and some problems with tools.

To make it easier, I did an improvised installer, based on Archiso and custom script. Just download the archive, extract it to the root of FAT32-formatted USB drive, and boot tablet from it:

One thing though, the tablet of yours is ONDA V820W V5, while mine is V3. There are slight hardware changes, but I'm not sure what is different exactly. The image should boot, but touchscreen/Wi-Fi/Bluetooth/sound/etc may not work depending on what has been changed.
