Thank you for responding, could you mention in more detail which link I have to use? No matter how much I have tried, I can't do anything other than access the part of using a pendrive from UEFI mode or entering the BIOS.

I understand that I have to put the corresponding Flash file on a pendrive (without any specific folder), insert the pendrive and load from UEFI mode, is this correct?
[Miscellaneous Android Development] ViAlexSt:
Hire is the official page of the tablet, with links to Android and Windows images. Inside the archive there is an installation instruction (I don't remember in Chinese or English, but with pictures).

Firmwares on Needrom (download for free).

And there is a lot of material on the Russian forum 4PDA

I retired a long time ago, since the tablet died a heroic death (the child smashed it into trash)
[Miscellaneous Android Development] Im-Kane:
I'm sorry for the heroic death of your tablet 😢. More or less I have looked and I can understand something but not completely, how can I install since I cannot access any other way than the BIOS/Efi menu and select start from pendeive/windows, I have no option to start from android... I have tried all possible combinations but I can only access it somehow by pressing F7... I'm quite confused to be honest. Would there be any possibility of telling me step by step the correct way? Thanks in advance
[Miscellaneous Android Development] ViAlexSt:
Actually, apart from F7, nothing else is required from keyboard. The difficulty, perhaps, is in preparing a bootable USB flash drive, UltraISO is great for this (as far as I remember, some Chinese version). I don't remember what I used, perhaps a more convenient and simple Rufus program. There's my instruction on the 4PDA (translated from Chinese), but it's in Russian and I doubt that Google-translator will be able to adequately translate into English. Unfortunately, I don't have the enthusiasm to mess with it. But I have instructions in English for Chuwi HiBook (this is the second corpse in the closet), the hardware is exactly the same devices, respectively, the instructions are the same.
[Miscellaneous Android Development] Im-Kane:
Thank you very much for this contribution! The only bad thing is that I don't have a Chinese number to be able to register on the "baidu" website and download the files...

I don't know if there is any other place where I can download the BIOS, the Android ROM and the Windows necessary for me without registering model // Onda air v919 v9 // according to the original box it is not CH.

I have the ROM "V919 AIR 双系统黑金版中性固件（适用V7、V8、V9版本）-20160615" downloaded from this same thread (I think it's for my tablet) but I'm very lost with the whole flashing system.

Thank you very much for everything you are doing!
[Miscellaneous Android Development] ViAlexSt:
I finally figured out to look at the header of this topic: everything is there, both firmware and instructions, it's just that instead of the rooted firmware, you need to put stock one on the flash drive.
[Miscellaneous Android Development] Im-Kane:
Ok, I understand that I just have to unzip the file that I mentioned and insert it according to the instructions that you sent me on the pendrive to finally select the option on the tablet, am I wrong?
[Miscellaneous Android Development] ViAlexSt:
No, you're not wrong. For installation, you can take an international firmware (in the header of the topic as "20160531 - stock English firmware with Gapps"), and I outlined the process in "1. Brief manual based on the Chinese instructions" (well, maybe too briefly) - It's much easier to make a bootable USB flash drive with Rufus than with UltraISO, as the Chinese suggest.
[Miscellaneous Android Development] Im-Kane:
Ok, I'll do then as it says in the tutorial you sent.

I'll comment as soon as I make some progress.

thank you very much for your attention !
[Miscellaneous Android Development] ViAlexSt:
Good luck!
[Miscellaneous Android Development] Im-Kane:
Have a problem… What i need for enter in “DNX mode” if i only enter in this window? 😢
[Miscellaneous Android Development] ViAlexSt:
Tell me, why do you need DNX mode? Where do you see it in the instruction No. 1, which is for a complete Android installation? Don't mix it with the instructions for Android firmware with Windows saved.

The DNX mode works only for a live Android, your task is to reformat the internal flash memory with the recovery of the boot table. This is exactly what the full stock image firmware does.

Look on the Internet by searching for the phrase "Failed to locate emmc device path for specified controller: Not found", for example, here: https://www.alldocube.com/en/forums/topic/6856/

Yeah, I get it.: you took the instructions for the Chuwi, but there's firmware using the program, you need to flash from a flash drive, look at the Chinese instructions, maybe you won't understand everything, but at least you'll look at the pictures.

Do you have a Rufus program? Format flash drive in it as a "bootable for UEFI", copy the Android firmware files to it, then on the F7 keyboard, select the flash drive to download and that's it, then the process goes on without your participation.
[Miscellaneous Android Development] ViAlexSt:
Hi, did you manage to revive the tablet at least? Otherwise, you were hiding something, I hope you managed to do it.
[Miscellaneous Android Development] ViAlexSt:
Damn, how is there an appeal to a person?... I forgot how to do it....
[Miscellaneous Android Development] ViAlexSt:
It's just all very well and good, thanks for the feedback, but actually not so rosy: why no sound on the upgrade versions? This tablet, of course, a device to satisfy "geek needs". With this it's necessary to tinker, to bring to mind, because it's "a banana product, which matures at the customer" © grobi181. Next I plan to try to compile (or port) TWRP; make deodex custom ROM (beta already is); to edit gpt.bin to resize system partitions (deodex quite fit in the 1 gb, the free space will go to /date for the needs of the user).
[Miscellaneous Android Development] TheSource70:
Super firmware with gapps. Looking forward to the solution that restores sound in a firmware including gapps. Now either gapps or sounds. Thanks!
[Miscellaneous Android Development] ViAlexSt:
Version 20160216 with root, gapps and sound. But somebody prefers the latest version of the firmware (20160429) and the sound via bluetooth.

But I was haunted by the situation with the lack of sound on some parts of the tablets. Perhaps that this is determined by the version of BIOS. Can you tell the BIOS version of your tablet? Download BIOS easy: hold down the power button and volume "+". If the version Y05D010Ployer_X64 - sound is on 0307 and 0429. If other - probably the only sound on 0216.
[Miscellaneous Android Development] kaapama:
I tried to flash the rom with mirek tool. Onda is at DNX fastboot mode, but mirek tool says just waiting for device... I can access to the tablet while in android mode so cable works and the connection also. Any suggestions?
[Miscellaneous Android Development] ViAlexSt:
And you installed the drivers? As Mirek didn't answer my question about his wonderful utility, you can look at my manual to other resources.
[Miscellaneous Android Development] TheSource70:
BIOS

Managed to install 0216 (difficult to obtain tablet in download mode) and indeed sound is on now. Looked up my BIOS version FYI and it is Y05D008Player_X64. Solves my issues for now. Thnx!
[Miscellaneous Android Development] BarroTorino:
you can make a video tutorial ?
[Miscellaneous Android Development] kaapama:
Needed reboot, now works. Thanks and 20160429 sounds are working!
[Miscellaneous Android Development] perama:
I have an Onda v919 air ch dual OS tablet that I have bought from GearBest. My tablet has already Play Store and Google Apps and I am very happy with it! The only thing that I want is to root this tablet. Do you know a way to do this? Any idea?
[Miscellaneous Android Development] ViAlexSt:
Based on the availability of gapps, you have the latest version - 20160429. In it, by the way, there's a "su" binary, but how do activate root access I do not understand. Programs Kingoroot and iRoot not work. Introduction root-access via fastboot also hasn't brought the desired result. Therefore, one solution is to install the firmware with pre-rooted.
[Miscellaneous Android Development] ninno0:
After installing the ROM, how do I reinstall Windows? There is a guide?

The application of dual boot on windows where I find?

Thank you
[Miscellaneous Android Development] ViAlexSt:
Use the utility Mirek - Windows reinstall isn't necessary. For details, see the topic.
[Miscellaneous Android Development] ninno0:
In my case you need to reinstall windows.

My tablet is V7, but with only 10 windows at this time.

Where do I find this utility?
[Miscellaneous Android Development] ViAlexSt:
Do I understand correctly that the version 7, but only Windows is installed? Check your version of BIOS - dual-boot must be Y05D010Ployer_X64. Otherwise, most likely will not dual-boot. If you wish to reinstall all operating systems, use the user manual from my first post, if the utility Mirek - see here .
[Miscellaneous Android Development] ninno0:
I messed up.

My version has only windows.

So my bios probably is not dual boot.

In this case I can not do anything to put Android and Windows together?
[Miscellaneous Android Development] ViAlexSt:
I repeat: the problem is in the version of the BIOS. If different from Y05D010Ployer_X64 - there's no point in trying.
[Miscellaneous Android Development] grwho:
Can you give another link for the drivers, because this one doesn’t not work?
[Miscellaneous Android Development] trimix63:
Do you know if is it possible upgrade the BIOS firmware?
[Miscellaneous Android Development] ViAlexSt:
I hope that I will forgive Mirek for the violation of his copyright, but here's the full set

This can only be done by programmer (this model is just perfect - CH341a) - no other way don't know. But you need to have someone (such as myself) made a dump of BIOS. I suspect that Onda does not wait for the upgrade.
[Miscellaneous Android Development] grwho:
Thanks a lot !

Hi ViAlexSt,

Thank you very much for your support. works perfect!

[Miscellaneous Android Development] ViAlexSt:
You have a DIFFERENT model: not CH!!! And the firmware isn't suitable.

No new firmware version, unfortunately... The one you mistook for a new, byte-by-byte comparison to exactly the same already available.

I know people who have opened the tablet and changed the thermal paste. But here we must be careful: the touch screen is very delicate. In another case, you just have to wait for firmware updates.
[Miscellaneous Android Development] ViAlexSt:
You need to clarify your model - the Chinese made many kind of similar, but actually different models. Well, if I have correctly identified your model, the threads either here or, for example, on 4pda ONDA V919 Air (Quad Core).
[Miscellaneous Android Development] GreatStorm:
If you do not mind , I'll post some screen done with CPUZ so you have all the details that I hope will serve to help me :)
[Miscellaneous Android Development] ViAlexSt:
I don't mind, but I'm afraid I can't to determine model. The main difference is the processor, it's necessary to focus on it. You can specify the parameters of your model here.

And RAM isn't 4 gb... Processor Intel Atom Z3735F. I find it difficult to say exactly what model. Like Onda V919 3G Air, but without a GSM-module. The Chinese are big on secrecy.
[Miscellaneous Android Development] GreatStorm:
In your opinion I can try to flash the last firmware for that model?

Inviato dal mio Elephone P8000 utilizzando Tapatalk
[Miscellaneous Android Development] ViAlexSt:
Well, the firmware from this thread, clearly NOT. But I don't presume to counsel: possibly suitable firmware for the model with 3G, which I previously gave the link.

Mirek was allowed to use his tool, I will make a English manual.
[Miscellaneous Android Development] grwho:
I have installed the 20160429 firmware and everything is working fine (including sound).

But I’ve observed a severe battery drain problem. For example the tablet during the night (8 hours) lost 30% of the battery!

Any suggestions are welcome.

MicroSD ext Android problem

I have bios version Y05D011Ployer_X64

I installed version 29/04 without reinstalling WIN and sound is on and the tablet work fine.

In my case I have only encountered a problem: by inserting the microSD slot in outer and moving from one system to another, with Android leaked permits write hanging the system, and to restart stopped at the error check on the card, while in Win10 was all perfect.

I put 64gb Samsug EVO, 32gb Samsung EVO, 32gb Samung EVO +, but the result was the same .....

The symptoms do not occur by inserting 8GB card and then to 16GB SANDISK ULTRA cl 10.

I think then that there is incompatibility with this brand of MicroSD, but incorporating them into other devices work perfectly, or on the ability of those who, over the 16gb Sandisk I could not try because I'm not.

Someone found me my same problem ??

Thanks for the support received, the Android rom works perfectly and the sound is ok !!

Thank you! :)

I've tried install 1602 version by using the tutorial and choosen the clean install option. But, after mirek finished the process, my tablet wont turn on. Then, after a couple of minutes to try push power button, my tablet suddenly on, but show an error in windows, then when I reboot in android, OS just show such like hard reset? There is no gapps and root access.. How could it happen????

Clear install implies ALL is erased, so you must reinstall windows, you have erased it because you didn't read carefully. Sorry if I sound a bit rude, but don't blame [MENTION=4943537]ViAlexSt[/MENTION] , h is doing a great job, it's THE only improving our tablet.
[Miscellaneous Android Development] ViAlexSt:
You with the device isn't wrong? You have accurately v919 Air CH? With processor Intel Cherry Trail z8300? I ask this because very often people make mistakes. Long not turn on the device - this is a weak point of this model. But that was a problem with installation of system - the reason can't even suggest. Method of Mirek I unimaginable number of times re-installed Android - everything is in place, everything works.

No, absolutely not: Windows remains in place ALWAYS when using the method of Mirek. I always use 2 "clean" - Windows works.

My mistake, I have mixed ideas, sorry.

With the boot.img for 0216 you provided in http://xdaforums.com/android/development/root-how-to-root-access-tablet-onda-t3396299 and latest rom you provided in this tread, 0429 version, I have sound (I have bios that doesn't support sound with latest version). Thanks!!
[Miscellaneous Android Development] ViAlexSt:
Now try the NEW firmware - V919 AIR CH 中性固件（适合014版本以上BIOS-20160531 (direct link) - Neutral English firmware for 014 version of BIOS. I sure as hell still don't understand anything in the numbering Chinese BIOS, but with my Y05D010Ployer_X64 this firmware is installed and works perfectly (sound is). The firmware already has a more finished look: no Chinese apps at all, Gapps in a wider range. And has a binary "su" - some Chinese superuser, but how to activate root access is still unclear. So here I have added Root+TWRP for this version.

And another important point: in the archive with the firmware is missing some installation files: need to add from any other version.

I'm not sure whether to make version for installation in TWRP or just completed img.
[Miscellaneous Android Development] mismamente:
Already downloading.

What files are missed?
[Miscellaneous Android Development] ViAlexSt:
Unpack into folder 'rom' (Mirek flash tool)

With boot.img 0216 sound will be back and CPU will change frequency (much cooler), but come problem with the launch of the tablet after sleep.
[Miscellaneous Android Development] zephyr_battle:
No, I have the right device, and I have checked it using CPU-Z. And Now, My device running on 0220 version? IMO, there are some question I have to ask u.

1. In the forder rom, there is a file "Flash Rom.json". Is it need to delete or not?

2. Do I need to extract the rom or just copy the archive then run process??
[Miscellaneous Android Development] ViAlexSt:
How to know the installed version I wrote here.

Delete anything not necessary, all as it's. The archive with firmware unzip to folder "rom", to start the process of flashing to run the file FLASH.bat.
[Miscellaneous Android Development] zephyr_battle:
So, I have to delete that files? The "flash rom.json" rom come from mirek archive..

Then, i have to unzip the firmware? In your instruction, you just say to copy the firmware.. What shoul I do actually?

Thanks
[Miscellaneous Android Development] ViAlexSt:
I don't know what difficulties make you feel? What could be simpler: unpack the firmware in a folder "rom" and run the file FLASH.bat. Nothing more needs to be done.

[Miscellaneous Android Development] mismamente:
The problem with no sound is different sound chip (as it's said in the chinese forum), so latests versions of tablet has sound because kernel has support for latest chip, not ours. The only way to have sound with our tablets (sound with feb firmware, not posterior firmwares) is to change the boot.img and use the version from february, because boot.img has the kernel, so it has the drivers for our sound chip.

You can use the 0216 boot.img from [MENTION=4943537]ViAlexSt[/MENTION]

I warned about this:

Try Remix is specially made on base of the version 0216 (forgive me ronek, the author of it, for duplicate links, but their Chinese site just without authorization do not download): download

In General, for earlier versions of the tablet are one version of Android - 0216. All others, including Remix, for the subsequent modifications. But version 0216 is a significant drawback - the CPU runs at maximum frequency and the tablet turns off from overheating.
