I tried it several times, but unfortunately it was unsuccessful.

The main problem is that bootloader is locked and there is not any button in developer tab to enable OEM unlock.

I also tried “Intel Android Devices Root / Temp Recovery Session” in blow link;

http://xdaforums.com/android/development/intel-android-devices-root-temp-cwm-t2975096

But it didn’t work for me.

Then I downloaded official ROM “V80SE_1.0.1_V1_Android5.1_20160908.rar “ from the below link:

http://www.onda.cn/Tablet_Supports.aspx?id=344

Then I followed “Root tutorial for intel atom Cherry Trail dual os tablet” from the below link:

http://xdaforums.com/android/development/root-tutorial-intel-atom-cherry-trail-t3468330

But I couldn’t find “\initrd\init*.rc”

Therefore I’m still seeking for a solution to root my “ONDA V80 SE”
[Miscellaneous Android Development] wgarnett:
my tablet use enable OEM unlock from developer option don't work too

but I run cmd in fastboot mode

fastboot oem unlock

it work , you can try unlock bootloader first and then try root tool again
[Miscellaneous Android Development] ar_sot:
I didn't get your point

Please explain more or give me a link in this regard
[Miscellaneous Android Development] wgarnett:
developer option of my tablet has "OEM unlock" option , but when I enable it , after enter fastboot mode , message show OEM is lock

otherwise , to unlock OEM using developer option is no useful , you need do steps below

1. install intel driver

2. reboot tablet to fastboot mode first (my tablet press volume - key when reboot)

3. connect otg/usb line

4. use PC to unzip root.zip and put to c:\ , and then run cmd , and type : fastboot oem unlock

after do these steps , my tablet is surely unlock OEM

and then you can try root tool (http://root.mgyun.com/) again

http://www.mediafire.com/file/un5eziwv6j3vd1g/V80SEboot_modified.zip

rename one of them to boot.img and then enter fastboot mode to flash it into tablet

try signed version first , if not work , try unsigned version

if work , then you also need to find a suitable twrp version to enter recovery mode to install supersu zip

ex : google search z3735f twrp to find some other tablet twrp to try

I've tried both bootfile and now tactile wont work anymore.

Have someone the original boot.img ? Because I don't know for wich reason I'm Unable to dowload the V80SE_1.0.1_V1_Android5.1_20160908.rar

More than that if I re-lock the oem my tablet juste wont boot anymore.

So my only option is to push by adb the original boot.img or to find a link to dll this V80SE_1.0.1_V1_Android5.1_20160908.rar .

Factory reset dont make anything.

If someone can help me =)

That's why i think the tactil screen don't work anymore.

Need your expertise :

1- should i replace the boot.img for my version (If i find it)

2-update my systeme using the V80SE_1.0.1_V1_Android5.1_20160908.rar

Other question :

To update my system manually, I have to push every .img file in the tablet with fastboot ?

Or i only have to use adb sideload to push the .rar (I'm not sure that .rar work anyway in sideload)

Sorry for disturb you :S And thank you for your time and your help
[Miscellaneous Android Development] wgarnett:
as above red words
[Miscellaneous Android Development] arwase:
Thank you for your Help !

So finally i get throught.

My tablet hadn't Dualboot anyway. It was android single boot.

After I brock the tactical screen. I have been to the fastboot menu and I flashed files using the V80SE_1.0.1_V1_Android5.1_20160908.rar that you gave me.

I've start with boot.img then recovery.img and terminate by system.img When this end i Reboot tablet and now tactil work great.

Thank you for your time again and your help was very usefull ! Thank you for your link also. I was not able to download it using the website I don't know why. It appear that for the systeme I'm still In V80SE_1.0.1_V1_Android5.1_20160830 But i don't care my tactil work again ^^'

Thank you for sharing these the helpful links!

I have some troubles flashing system.img --or whatever other .img-- on my Onda V80.

While I am in fastboot, after sending the "fastboot oem unlock" command, I can see the line "LOCK STATE" switching from white to red and showing "unlocked", but every time I try to flash something, I get "FAILED (remote: Flash failure: Not Found)" on the computer, and "Failed to get partition [the_name]: Not Found" on the tablet screen.

It is the first time I am facing this kind of problem (I also have a Galaxy S4 and Honor 5X), and I am unable to find a solution after almost a day.

Thanks for your help!
[Miscellaneous Android Development] NeO-TuX:
On dual boot tablet, it seems like it is not possible to root Android while Windows partitions are still present on the tablet.

The solution is to wipe all the partitions, which is automatically done while reinstalling Android firmware.

I hope this piece of information is usefull!

Hey guys, what's the simplest way to flash the newest official ROM for Onda V80SE Android only version?

I saw thare is available a link to a 20161026 version on this forum (i'm on 20160830), but no instructions to flash. Thanks
[Miscellaneous Android Development] nonsenses:
Not working at all,

Mine is V5 too and i got bootloop on android start and no windows.

Both roms "v1" and "v3" obook 20 plus you can find on forums didn't work.

I received my onda obook 20 plus with a lot of bugs, reboots on both androids and windows... that's why i tried to flash it but don't work.

fortunately I made a backup before flashing with macrium reflect and was able to restore it but I'm stuck with with the same reboots problems and windows blue screen and sometime android bootloop.
[Miscellaneous Android Development] vkass:
I don't experience any of those with mine, what date is your build? Did you try to check for updates on both windows and Android?

I just wanted to root this thing with the firmware.
[Miscellaneous Android Development] nonsenses:
i can't tell you : my android DON'T BOOT AT ALL, i can just run windows 10, 1/4 time.

Could you make a working backup with macrium reflect 6 and send it to me via MEGA or anyhoster else?

Also i tried to install remix os 3 pre-rooted but after install it don't boot. I don't care about windows i better prefer android with the full 64GB space.

Hi everyone!

I've just installed the v80plus version. I tryed in the past the onda official version and, compared to those, this is really smooth and works really nice, but I have only a 5 GB memory, instead of the 32 GB it should be.

Also my tablet charge till 45% to 65%, then stops. I tried several times to recalibrate the battery but without success.

Someone can help me?
[Miscellaneous Android Development] banjicom:
I don't really know how to check the version of my obook SE. I only assume it is the V5 version because i check the S/N at the back and i see V5 among the numbers.

Is there any other stock or custom android rom you can recommend for me that will work on this tablet apart from the official remix Os which is very limited and make the tablet uncustomizable

Do you think the version V3 rom will work on the version V5, i don't want to brick this tablet.

Thanks.

HI,i instaled windows 10 on onda v80 se,now i can not get touch screan to work. Any healp pleas. any healp pleas
[Miscellaneous Android Development] terradrone:
I'm wondering the same thing. When i got the v80se i mistakenly tought the cherry trail device, being it intel x86(64) , would be able to run win10. After finding all drivers except the touch drivers it was clear "normal" win10 wont be running on this device. So i was hoping to run android on intel.

Now i got the 20161026 android package, extracted it to usb drive, but there is no efi folder and the (32bit) efi from the v80se cant boot.

I'm also confused in that some speak of "fastboot". I'm familiar with fastboot on arm, but as far as im concerned the v80se is a genuine intel "pc" with x86 cpu and a "normal" efi (succesor of bios). The only drawback is that most intel cherry trail devices, although having a native 64bit cpu, have 32bit efi's . Therefore one can only boot 32bit os-es . Or you have to be willing to go the linux route, using grub to engage 32bit efi and after that booting 64bit code.

Maybe someone can shed a bit of light on this toping. My only goal is to run android with gapps on the device, because i gave up on win10.

How can we help you if you didn't even bother to write tablet model? My ONDA oBook 20 plus has S/N PO20......V5A03885, so it's version V5. V5 are 9th and 10th digits of 16.
[Miscellaneous Android Development] dozebox:
I have onda v820w ch v1, but it's a single os version. It has only windows 10. I'd like to replace it with android only (or atleast dual os if can't do just android).

I downloaded "V820W CH 中性固件（V1版本）-20160614.zip" and tried to go to EFI to flash it, but it says "image type x64 is not supported by this ia32 shell". I have read about this and the fix was that I'd need to boot into android first. But the problem is that I do not have android in this tablet.

So is there anyway I can install android to this windows only tablet? The bios of mine looks different what I've seen in screenshots. It goes straight to the "normal computer" looking bios with continue, boot manager, etc options. Doesn't have the graphical ui for the options. If i go to the bios utilities (SCU in the graphical ui?), i see all kinds of options for android booting and OS selection, so I'm guessing the bios already supports dual os, but I just don't know how to get android installed.

Anyone to point me into the right direction?

EDIT: And my device S/N is P820CBFAV1A00833 if that helps anything.. is this Onda v820w CH v1 or v1a?

[MX Player] almararn:
It would be great to have information from MX player on Android Wear when using it for music, and basic controls.

Also the ability to add network folders to MX player.

And the ability to have MX player seek entire video/audio to temporary location whilst playing it from network.

A simple MX player widget would be great to have as well.
