I flashed Sailfish to the Volla Tablet and it works pretty well. If anyone wants to try it, here are the instructions:
- enable OEM unlock and USB debugging
- Put the tablet into fastboot mode (vol up + power)
- Unlock the bootloader with the command “fastboot flashing unlock”
- Reboot the tablet
- Bring the tablet back into fastboot mode
- Navigate to the folder containing the flash.sh file
- Open a terminal and run the command “bash ./flash.sh”
- Reboot and (hopefully) enjoy..
