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

I assume there's been no change in this issue lately?

(I admit I haven't been paying attention very closely as I've used my Onda quite sparingly.
Sure, there is the Youyota tablet option and I might still actually end up getting one but in the meantime I will also gladly welcome any possible SFOS updates for Onda.)

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

I love to use my Onda V820W V3 with SailfishOS. By far, the best OS for tablets without doubt. Almost a year using the Onda and quite happy with it. Now I've backed th Youyota so I hope I can use Sailfish for at least another year! :)

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

Excited by the idea to run SFOS on a tablet, I ordered myself an Onda V820w V3 which just arrived today.

Problem: I am stuck in an infinite boot loop. :(

What I did: I used the automatic installer including ferlanero's suggestions mentioned in posts #54 and #55. Installation finished with a reboot. After that, all I see is the GRUB menu "Sailfish OS" or "Sailfish OS (USB debug mode)" which, when selected (either one), results in a black screen and a reboot.

Can anyone help, please?

Is it Onda V820W, not Onda V820W CH? Not sure if original one can be found anymore in shops.

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

Thanks for the quick reply, TheKit!!!

I bought it used. The SN starts with P820DBF4V3A... and the package doesn't say anything about CH.

Sticker:
Onda V820W DualOS 32GB
Screen: 8.0inch display (1280x800resolution)
CPU: Intel Z3735F,64-bit,2M Cahce, up to 1.83 GHz
GPU: Intel HD Graphics
...

P.S. Argh, Sticker may not belong to tablet since it has a different SN (for V1). But the SN quoted above is on the tablet itself.

P.P.S. How would a regular V3 serial number start?

P.P.P.S. It's working now!!! All I had to do was to reset BIOS to default! Man, this was stressful... :D

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

Did you boot Windows before installing it? UEFI has "Android" and "Windows" modes with different quirks to boot them.

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

Thanks again for the quick reply, TheKit! I owe you one!

Yes, I did boot into Windows first, basically just to check whether the device was working at all.

One thing I noticed: When I first charged it, a red LED lit up. It no longer seems to do this. Yet, SFOS reported "charging". Is that normal?

Would it be possible to add some information like posts #54/#55, the serial number and the BIOS reset thing to the first message in this thread? Future users might appreciate this.

BTW, I'm just running the 2.0.5.6 upgrade (19%... fingers crossed!). Are there any chances for a 2.1.x upgrade?

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

Here's a funny thing after the upgrade from the installer image to 2.0.5.6.

Instead of the normal "unlock" screen with the "> <" symbols I now just get a black screen with the rotating circle. :confused: At first I thought Lipstick hadn't started until I tried swiping.

Is there a method to remedy?

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

I didn't reverse the kernel part to light that red LED, since on Android it's only lit when charging, so this can be ignored.

I planned to update it to 2.1.x, but still didn't do it. Will try to check it again.

That's weird. I didn't see this on tablet. Usually this happens when it's waiting for ofono, but we don't have telephony.

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

Oh, that's fine. I just wanted to know if I "broke" the LED functionality somehow. You are absolutely right, nobody really needs that LED.

I re-ran the upgrade instructions again. It seems like I might have skipped the "rm /lib/modules/3.10.20/*.ko" part the first time around. So sorry about that... :o

It would so great if you could!!! Again, let me thank you so much for all the wonderful work you did here! It is truly appreciated!
