Your tablet is ONDA V820W V5 then. Hardware like Wi-Fi/touchscreen/cameras might be different, but it should boot at least. You need to have 100 mb EFI partition and copy GRUB/kernel there, and ext4 root partition, large enough to contain Sailfish OS files.
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).

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.
