Android working fine, but SD card stopped working in windows. Any driver or something?

SD card working again!

It worked! Thank you SO MUCH! I only had to eject and return my SD card after the "instalation and reboot" and it now recognizes my SD card correctly! Thank god, since I have installed a few games there (Warcraft III, C&C Generals, Doom 3, NFS: Most Wanted, FlatOut 2, UT2004...) and was scared that it will not work after Android flash.

From the page with the drivers, it wanted me to install some application of theirs so I found the drivers as a direct link in another page in the forum. I'm adding it as attachment, hope you don't mind.

Just one last problem remains, but it is more a problem with Windows and DirectX I guess. Some of the games (W3, C&C: Generals) are displayed rotated... They are trying to display in Portrait mode. Only fix I have found so far is windowed mode fullscreen (but I have to change resolution to 1024x768 on desktop to be able to play fluently). I tried compatibility mode, disable scaling, googling (found: https://www.vogons.org/viewtopic.php?f=8&t=46054 with no sollution). But this question is out of this topic, just if anyone knows anything about that... It really grinds my gears that there are so many problems with getting this tablet to work correctly (first the Android, then the SD card, some games do not display correctly...). But now when it is all fixed (except the games) it finally is usable :)
[Miscellaneous Android Development] ViAlexSt:
For other games I will not say anything, for Warcraft in the registry - HKEY_CURRENT_USER - Software - Blizzard Entertainer - Warcraft III - Video - try to change the settings reswidth and resheight for the required (2048 x 1536) or their multiples values. Perhaps this method will work for all situations.
[Miscellaneous Android Development] mazlixek:
Dont want to spam here

I have a version of W3 that does not require installation, therefore I have nothing about the game in registry. However I am able to change the resolution in game and it displays rotated for every one of them. I created a question here http://gaming.stackexchange.com/questions/270940/old-games-on-windows-10-tablet to discuss it at the right place, not here. Thanks anyway :)

I have the same device and the same issue !! Have you been able to find a solution??

Thanks!
[Miscellaneous Android Development] ViAlexSt:
I guess that we must not talk about version 5...7, but talk about modification/mounting of hardware and/or version of BIOS. I have v7 and BIOS Y05D010Ployer_X64 - no problems, neither with sound nor with sleep, etc. I distinguish 2 groups of tablets with dual-boot versions 5 and 7: on the first group to not complain, and the second is also very poor. How to fix the situation - I don't know. Might help to flash firmware BIOS, but maybe it'll kill the device - if the reason is hardware. I'm afraid that except the engineers Onda no one answer to this question.

V919 air CH single Os Windows 10 to single Os android

Hello everybody o/

Do you know if can I put android on this tablet ?

Or at worst in dual OS ?

What is the way ?

Onda V919 Air CH Intel cerise Trail Atom X5 Z8300 4 GB RAM 64 GB ROM 9.7 polegada IGZO écran Windows 10 Bluetooth HDMI

(Sorry, i can't link the link where i bought it because i m a new member)

Thanks you very much for reading me.
[Miscellaneous Android Development] ViAlexSt:
Pretty strange you desire, usually the opposite, get rid of the Android :D Personally, I don't know such precedents, but I can only share my humble thoughts:

- strongly suspect that the issue rested in the BIOS: the version of tablet is determined by this parameter; version of BIOS with support for Android isn't shared;

- for Teclast there are various options of memory allocation (gpt.bin), including fully without Windows partitions (1GB system 56.5 GB data); layout for Teclast should ideally be suitable for Onda.

But allows the BIOS with sharpening ONLY under Windows run Android??? That's the main issue.

And is a variant as Remix, but Remix isn't for tablet, but Remix PC: http://www.jide.com/remixos-for-pc
[Miscellaneous Android Development] azurha:
mmmh okay. Thanks you for your reply

But may be is it possible to transform my single os windows 10 to dual boot ?
[Miscellaneous Android Development] ViAlexSt:
It's this ability without proper BIOS just will not work.

[Miscellaneous Android Development] WillianGuerra:
I'm not able to install the rom, could pass me a step by step how to proceed.
[Miscellaneous Android Development] ViAlexSt:
What exactly doesn't work? How are trying to install the firmware? Flashing from the stick or by the method of Mirek?
[Miscellaneous Android Development] WillianGuerra:
I'm trying for Mirek 's method , I first copied the room files to the folder " rom " , went into flash mode, started the bat , it appears a blue screen with a few options on the tablet, but not the to select options .
[Miscellaneous Android Development] ViAlexSt:
It's on the tablet blue screen? You just loaded it into DnX-fastboot mode? On the screen should be a picture how show in my post #13 http://xdaforums.com/showpost.php?p=66835040&postcount=13 After run flash.bat the device starts into service menu, "normal boot" mode, without any blue screen. Still more questions than answers. Installed drivers? I hope, in the folder "rom" you don't placed firmware as zip-archive, but unpacked it.
[Miscellaneous Android Development] WillianGuerra:
sorry, I mistook the model of mine is the Onda V919 3G Air. Do you know if this rom works in this model? if the answer is do not know where I can find a custom rom for it.

thank you
[Miscellaneous Android Development] pouskidis:
I have 3 questions:

1) Do I unzip the contents of the firmware to mireks rom folder or just paste it compressed in 7z format?

2) Can I choose clean install without loosing windows? (I already know that, just want to be sure).

3) Do I have to reset to factory defaults after installing new firmware? If I do install 0531, will reseting to factory defaults return the chinese or they all remain english?

Thanks
[Miscellaneous Android Development] ViAlexSt:
Unzip. The contents of the folder should be as on the attached picture.

Windows will remain for any choice.

When choosing "2 - install android - clean install" nothing else to do. Chinese will come back only when flashing the stock Chinese firmware. But if you have already installed some Chinese program and select "1 - dirty flash", part of them will remain (located in the user partition /data).

Hi all,

I just bough a v919 air ch v7 (64gb rom + 4gb ram) with z8300 processor. When I receivd it, it was already initialized (strange .. being new!), so I reset android and windows reinstalling both OS. Android was 5.1 and the default background was a green leaf, but I'm not able to find that rom anymore, does anyone know what rom was and where I can find it again?

I reinstalled windows 10 too, but now I have only 22,5GB free (of 38,2) of my initial 64, and looking in disk management I see A LOT of partitions ... is it normal?!

Any feedback is really appreciated!

Thanks, cheers,

Pap
[Miscellaneous Android Development] ViAlexSt:
No.

Onda V919 3G Air (Intel BayTrail-T Z3735F) has its own thread: http://xdaforums.com/general/device-reviews-and-information/onda-v919-air-3g-dual-boot-9-7-t3015933. Ask there.

If your Onda V919 3G Air with MTK8392 Octa Core - I absolutely can't tell.

Version 20160531 has the background a picture of a green leaf.

You want to have for Windows 64 Gb and for Android 64 Gb? :eek: Buy a model with 128GB :p

Normal
[Miscellaneous Android Development] paprott:
Got it, I'll try to download and install it! Thank you!

You are right, but I didn't expect I would have only 38GB for the windows system, and so many disk partitions. It surprised me seeing 8-10 partitions inside the disk!
[Miscellaneous Android Development] ViAlexSt:
These numerous partitions are tiny size to 100 MB and don't have significant value. If you remove them, then after reinstalling Android they appear again (marking emmc memory is written in the gpt.bin file). The purpose of these sections I don't know (and didn't explore, in general).
[Miscellaneous Android Development] pouskidis:
Just installed 0531 version with absolute success! It is a great f/w version! Rooted it too.

This firmware is GREAT! It has only English, it lowers the brightness that was too much in original Onda chinese one, and it also has an app drawer. I LOVE it!

I have I have G4v7 revison and 20160323 version.

Everything works just fine!

If you do have similar hardware do try this 0531 firmware. It is simply the best!

Thanks ViAlexSt for all the effort! My tablet is perfect now! :)

If only I could remove those chinese from windows... I installed EN language but many remain, including loggin in and out... Perhaps change the user?

EDIT: Found that too! Follow the instructions here http://www.ondaforum.com/topic/2425-remove-chinese-messages-from-windows/ and it is English now! Although programs from start menu still remain in chinese. Tried to remove them, ended up deleting them and unable to restore them.

If I reset windows (reinstall) will I loose android?

Anyone can help??!!

hi all

I am getting crazy with this tablet :

ONDA V919 AIR DUALOS (only wifi)

SYSTEM (Android 4.4.4)

Android Version: 4.4.4 (Kit Kat)

API Level: 19 - Build ID: KTU84P - Fingerprint: ONDA/V919/V919:4.4.4/KTU84P/eng.ibuilder.20151014.105502:user/dev-keys

Processor: Intel(R) Atom(TM) CPU Z3735F @ 1.33GHz

the problem is this message : throttling brightness due to thermal event

I know I should change temperature settings - but i need it to be rooted - but I have tried with everything and it is not possible to root this tablet - there is no way to access to recovery - I have tried volume up + down and all others combs - and in any case I have read that even if I manage to root the tablet there will be sound problems anyway.

So my real question is : is there a way to suppress that FXXX message without root the tablet.

I am disposed to pay if someone can manage to do it for me - I live in Milan. Or please help me some way ...

thanks

Domenico
[Miscellaneous Android Development] pouskidis:
[MENTION=7576731]domedap[/MENTION] you post at the wrong thread. Your tablet is a different version. This thread is for CH version. However, since I also had your model, I can tell you this: You can check here for rooting it http://xdaforums.com/android/development/intel-android-devices-root-temp-cwm-t2975096

But it won't help with your problem. I had that problem too (there are many onda tablets with this problem out there, ch or not). I was forced to return the tablet because I couldn't do anything by tampering with registry after rooting it.. Seems it is a hardware problem.

I think a guy here have fixed it (has a CH version with the same problem). If you are willing to open it and remove a specific cable (thermal sensor) from the battery... Personaly I cannot help you as I havent done it. And I don't know if it is safe to do. It may have to do with faulty sensor or something.

After creating a new administrator user to get rid of chinese apps or reintall a few apps in start menu, my Onda v919 CH dual boot worked just fine!

This is a PERFECT tablet!
[Miscellaneous Android Development] ViAlexSt:
Yes, if your tablet is dual boot. But even in this case, there's a lot of nuances. Not all firmwares are equally suited to different revisions of the tablets. This situation is absolutely not clear. Except that only Onda engineers can clarify it. I can definitely say: if your tablet G4V7 revision (see serial number on the back cover), you can install any firmware (except February 0216 - no audio).
[Miscellaneous Android Development] gigitaly:
Someone has slow recharge when tablet is poweroff? it's this only my problem with Rom 29/04 and Twrp installed...
[Miscellaneous Android Development] niko00:
are new official ROM outputs, let us know if there is any improvement!

And as always Thanks! ;)
[Miscellaneous Android Development] ViAlexSt:
I have a feeling that I alone have to answer questions. It's sad :( But I answer to the question: there are no apparent changes. The firmware is full of Chinese, but with Gapps. When comparing the bits with no significant differences. I made a version for installation in TWRP, without the Chinese, rooted and with some improvements. If it is necessary - will share.
[Miscellaneous Android Development] ViAlexSt:
Ladies and gentlemen! Good news! After upgrading the BIOS when you install the latest versions of the firmware HAVE SOUND! This is true for version V7, which is checked by revisions G2 and G3. To revision the G4 of course. The pack can take either from the original source or my link. For updates in Windows to run the flash.bat.

V919 AIR CH DUALOS _v117
[Miscellaneous Android Development] ViAlexSt:
You should install the version 0531. Version 0706 is no different, but packed full of Chinese software.
[Miscellaneous Android Development] demons77:
Thanks, entonces no lo instalare, muchisimas gracias por todo.
[Miscellaneous Android Development] 953091:
The latest stock English firmware with Gapps is 20160729 :

Download from yun.baidu.com (sort by modified date DESC)

I can't see what's different from 20160531, the kernel is still 20160531.
[Miscellaneous Android Development] ViAlexSt:
It's NOT stock English firmware. It's stock Chinese firmware. But with Gapps. The difference between them is microscopic.
[Miscellaneous Android Development] 953091:
Yes, 20160729 is stock English firmware with Gapps,

Need help with drivers

Just needing help with doing the mirek method. Can some tell me step by step in greater detail because I am bit lost. Not sure where to put drivers and whether I put them on PC or tablet. And what do I do with the Intel flash tool. Really lost and maybe just a little bit slow. Sorry about this but any help would be great. Thanks a million. I have the v919 ch g4v7 with Android 1.0.0_v5 firmware and build 20160323.
[Miscellaneous Android Development] ViAlexSt:
What's the specific difficulty? In post # 1 have all available, and drivers, and Mireks script. Installation procedure is simple and the steps are described. The firmware, of course, install from your desktop computer.
[Miscellaneous Android Development] slainte13:
I download the drivers and install them from 1 2 and three and then open the intel flash tool on my pc. Then unzip rom and unzip mirek tool and merge them in one folder called rom, also on my pc.

then get my tablet and put into fast boot mode and connect via usb cable to pc. check to see it is recognized in intel flash tool. Then I go to rom and double click flash and follow on screen prompt for a clean install. Is this correct see pics of result. Thanks for your time and efforts.

Results seem no different. Tablet still states same firmware before upgrade.
[Miscellaneous Android Development] ViAlexSt:
Where does it say that you need to use Intel Phone Flash Tool? This program is needed only as a driver installer.

And where did you unpack the contents of the archive with the firmware? The subfolder "rom" is part of the Mireks script.
[Miscellaneous Android Development] slainte13:
Thank you

Thanks a million. Managed to get it flashed successfully :D.

I had been putting mirek tool into ROM instead of other way around.

Just one more question I have weak with Fi . Just wondering would you know of a fix.

Thanks a million for all your help and patience.

Hello,

I have got the onda v919 air ch 64 gb Tablet. After a try to reset the installed windows 10 System with the "reset the System" option from windows the tablet does not work anymore. I see only a short time the onda logo and after this the screen is black.

Than I install your rom looking forward to start android on my onda. But after flashing I Hve still the problem. Short time a smal onda logo than it change to a big onda logo and than happen nothing at all.

Do you have a idear what I can do now?

Thanks for your answer.

Greats

[Miscellaneous Android Development] fturioni:
Same problem with win 10 restore here. First be sure you have the dual OS version of V919 CH. I used stock english image 31052016 (last one in the list) to recover Android and worked flawlessly. I don't know if it matters, but I first selected Android OS image in bios.

Hi!

I have an onda v919 air ch no dual bios with windows 10. Can I install Android instead of Windows 10?.

Thanks a lot!.
[Miscellaneous Android Development] ViAlexSt:
No, without the support of dual-boot in the BIOS. You can try to install Android as Remix in version for desktop PC. Onda BIOS shared for the upgrade, but in your case, you need a programmer.

Thank you!!!!

Two G2V7 versions without sound now they both have sound!

Now I need to fix the stupid bug about Thermal Shutdown. It happens when not plugged to charger. If plugged to wall charger, no thermal shutdown.
[Miscellaneous Android Development] ViAlexSt:
Have to open the back cover and to modify the cooling system. In the original, as the heatsink uses metal back cover. On the protective cover of the CPU has a thermal pad for contact with the back cover. Bad contact -> bad cooling -> overheating of the CPU. Usually add an additional sheet of thin foil or a copper plate. Well, not bad to check the contact of the processor with its protective cover.
[Miscellaneous Android Development] mismamente:
Can you explain a bit more (with photos if possible)? (The 4pda.ru forum shows error 404 when trying to view thumbnails in full resolution)

ATM if fixed it (risky, but fixed) modifying /system/etc/thermal_sensor_config.xml

I have changed in battery section the settings 20 degrees more (if first was 5000 I changed to 7000 and so on with the other two)

Now thermal shutdown not happening from yesterday.

But if I can open the tablet and fix (with photos to know what to do) I will do (and also I know this is also risky, and my sole responsability if it goes wrong)

Kind regards
[Miscellaneous Android Development] ViAlexSt:
Risk no. Just corrected a build error. In my tablet the contact of the casing of the CPU with the back cover is good, so there is no overheating. I'm attaching 2 photos, the first is mine, without battery (I drew the circuit), but with indicating the termal sensor. This is for common understanding. The second photo from the forum 4pda (I translated labels; the original is here), which shows a modified cooling system of the processor and eliminated the heating of the temperature sensor of the battery. In the second photo isn't visible, but on the cover of the processor initially no thermal pad! Therefore, overheating. Under foil, you must put a piece of usual paper to avoid short-circuits contacts. Cut the foil on the back cover and a piece of foam to prevent heating of the battery temperature sensor.

Hay algún modo de volver a tener win10??

También he estado probando un poco Android y el wifi es muy malo ¿es normal? tengo una Tableta bq de hace unos años que va mucho mejor en tema de cobertura.

La respuesta del botón de encendido es un poco lenta ¿también es normal?

de momento sigo trasteando con la Tablet a ver que tal.

[Miscellaneous Android Development] ViAlexSt:
A couple of pages ago in this thread I was shared. But the patch only for Windows. For Android will not help.

If you're ready to open the back cover, you can improve wi-fi to attach any wire to contacts its module (for better understanding see the pictures)

For this model a common event.
