so you can use google maps integrated in other apps for instance?

Re: Sailfish OS on ONDA V820W V3 and other Intel SoC-based tablets
 

I got my V820W V5 a couple of weeks back but only now have had some time to toy with it.

With the automatic installer from the first post I got Sailfish on the tablet yesterday - only needed to comment out the Russian locale (maybe worth a mention in the first post?)

Ironically, sfos.scanf.su site was down at the time so I wasn't able then to update to 2.0.5.6 using TheKit's instructions on page 9, so I tried the tablet as it was. Due to a bunch of little annoyances I was a bit disappointed (had trouble with the wifi, the system time wouldn't update neither could be set correctly, ambience setting would reset after boot etc). Today, I could finally run all the commands to update to 2.0.5.6. (Some files were not found in the Jolla repository and I had to choose 'ignore' 3-4 times near the end but it didn't seem to hinder anything.)

After the boot... color me impressed! Using the tablet feels pretty sweet even though the sound is not working (which was expected). I'm not claiming that everything else works 100% as I've not used it that much yet, but I haven't really found a reason to complain, either. For roughly 80 euros the tablet already seems like a more than adequate substitute for a real Jolla Tablet where I'm concerned... others may have different opinions, of course.
Great work TheKit!

I did update the tablet's BIOS in hopes of maybe getting the sound to work as I read somewhere that this update will fix it for Android. No such luck with Sailfish.

Another thing I haven't been able to do is install Linux on the tablet. I've tried with different versions of Linux Mint but the display keeps staying blank after boot despite tries with different parameters e.g. 'i915.modeset=0', 'nomodeset', 'grub_gfxmode=1280x800x24', 'acpi_osi=Linux', 'i915.broken=1 i915.alse_backlight=1' etc.

Re: Sailfish OS on ONDA V820W V3 and other Intel SoC-based tablets
 

Did you try i915.fastboot=1 with 4.7 or 4.8 kernel? The very latest ones probably need hack mentioned there.

Re: Sailfish OS on ONDA V820W V3 and other Intel SoC-based tablets
 

Thank you for this! I managed to boot Linux Mint 18.1 with quiet splash removed and i915.fastboot=1 added.
(EDIT: removed the video parameter as I don't seem to need it, after all)

I noticed the screen won't turn and I have't tried installing but at least now there's a way to use GParted for e.g. enlarging the sailfishos partition size if needed.

Do you have sound in Mint or anything about sound chip in dmesg?

Re: Sailfish OS on ONDA V820W V3 and other Intel SoC-based tablets
 

Unfortunately, no sound. Here is the dmesg output after boot, didn't see any mention of rt5640, though.

[ 38.438878] sst-acpi 80860F28:00: No matching ASoC machine driver found

Yeah, not really helpful. If someone still has Android on V5, would be good to get dmesg from it.

Re: Sailfish OS on ONDA V820W V3 and other Intel SoC-based tablets
 

did any of you try "installing" the driver or is it even possible in sfos to install drivers like in linux?

Re: Sailfish OS on ONDA V820W V3 and other Intel SoC-based tablets
 

Well, on V5 we're missing sound codec driver and machine driver for that codec. It's implemented in kernel, so it can't be easily "installed" both in Linux or SFOS.

DSDT dump can be useful to at least identify the codec:

Not sure what you mean by that? Maps and Google Earth work fine, aso some other apps that use play services to my knowledge.
