Onda V820w (V3) manual install guide
Make sure you have USB keyboard and OTG cable, it's required for navigating in UEFI setup.

1. Make ext4 partition at least 2 GiB large on your microSD card. GParted is your friend in this. It's also possible to use internal NAND, but this would require booting Linux LiveCD on tablet for partitioning, using microSD is easier and safer for testing.

2. You can either download Jolla Tablet firmware yourself and extract root/home partition. On Jolla Tablet LVM is used with separate partitions for root, /home and /fimage (recovery images). I didn't use this structure since it complicates testing and amount of available space on tablet is pretty low, and instead moved /home contents on root partition. /fimage is not needed since we don't have recovery images anyway. Then overwrite the contents of root partition with the contents of "root" folder from https://github.com/NotKit/sailfishos-onda-v820w-overlay.

Or you can use the rootfs tarball I prepared (Sailfish OS updated to the latest version): https://mega.nz/#!cBZ2XZ6L!P3EIFFQze...6lNcJnyOvjsArA

3. Now you need to adjust the contents of grub.cfg in /boot.
root= should to point to the right partition, /dev/mmcblk1p2 by default for second partition on microSD card.
Since the tablet can't boot from SD card, we need to copy bzImage, grubia32.efi and grub.cfg from /boot to the root of internal NAND ESP partition. If you have root access in Android, you can mount it like this:

Code:

su
mkdir /data/local/esp
mount -t vfat /dev/mmcblk0p1 /data/local/esp

4. Connect USB keyboard and reboot the tablet, holding Esc key. It should go to the boot menu. Select "Boot From File" option and chose ESP partition in the list, then launch grubia32.efi.

The first option in GRUB should normally boot Sailfish OS. First boot is going to take around a minute, but If you have black screen for too long, try pressing power button.

The second (init-debug) enables USB networking and telnet daemon as specified in 9.2 of HADK porting guide. It halts booting until you connect via telnet and tell it to continue, so don't expect anything but black screen until then.

Here are some photos how it looks like if you get it running: http://imgur.com/a/2CIVo

Hi, sorry for replying so late, but this really caught my attention as it could be a cheaper alternative to the Jolla Tablet. First, I want to thank you for the detailed tutorial and for the effort.

Would you (or anyone else with this tablet) please be willing to share any experience with using it for a few weeks?

What about the battery life? How much power does it draw when idle?
Does the miniHDMI-out work?

And the final question - since the port is based on the Jolla Tablet files (if I understand it correctly) and it uses the same kernel version, do the proprietary parts of SailfishOS work as well? Namely Alien Dalvik, Jolla Store and MS Exchange (never used it, but I'm curious).

Thanks.

I think, now you need to put your Tablet into Flash mode and flash it with Intel Phone Flash Tool or Intel Plattform flash tool
