Mine LITERALLY goes off. I have to power it on again... I'm guessing we could be facing similar issues.

Lets hope someone has got what is needed to fix this... I have to send my laptop to maintenance and bought this tablet specially for college while I don't have the laptop... I'm desperate for a solution hahahaha
[Windows 8 General] reggiexp:
yeah i tought it was off unitil i saw in the light that it was acualy on. but no backlights very wierd. so every time it dies on you its on, cause when you plug in a usb you hear the sound. but it imposible to get it on normal so force shut down. but yeah at the end its the same problem the screen won't turn on.
[Windows 8 General] dani7710:
before closing I'd like to know what you think. the black insulating tape is because there are components that must not touch. suffice? copper is 0,8mm thick and closes perfectly, and removes the noise at the edges of the plastic

But I have not tried to turn it on because I still have to put the thermal paste

any comment I will be a great help!

as you can see I removed the tape where to touch

I made a hole because that chip is better than dissipated, however I could not use copper. Used thermal pad

Thermal paste

fixed with adhesive tape and thermal pad in the hole

[Windows 8 General] reggiexp:
hey dude. just curious. what version of the voyo you have. and what touchpanel serial code you have? and what touchscreen driver you have on in bios?

i have a F version and the touchscreen they sell are not the same serial code. (but it should work i guess)

just wanna know a bit more about things.
[Windows 8 General] dani7710:
Im have mainboard version 6.1 3735F
[Windows 8 General] reggiexp:
Okay F also.

Im still not sure if i should buy a new touchpanel.. One side says yes. Other side says no its not worth it. And im not even sure if it will work. (evn if in bios i can select 3 other touchpanel drivers) im scared that it won't work.

Its only 15euro. But the tablet keeps on dying on me. (coma witch is anoying)
[Windows 8 General] dani7710:
I think you will work

Camera drivers?

I've got an odd problem with my VOYO A1 Mini (the Z3735F) .

When I recieved it, the cameras didnt work.

They just showed up as unknown devices. So i did the normal thing, looked around forums and such (including this one) to see if i could locate the drivers, since windows update couldnt find them.

I tried downloading ALL the driver packs i could find, the camera drivers from this post, and still nothing. In the end, i tried doing a more advanced search, looking for the hardware ID which is: OVTI2680.

I managed to find a driver which someone posted for the Pipo W2 tablet (i think) and it was marked as a Rare camera driver (which was the OV2680).

So i installed the driver, and (although unsigned) it worked. but with a few major problems. Which is why im here to see if any of you folks can help out with it.

Both cameras on the Voyo I have (the rear and front camera) have the same Hardware ID: OVTI2680, and both accepted the OV2680 camera driver i was able to dig up.

But when installing these drivers, both cameras show up in the "System Devices" rather than in the Imaging devices or just showing up as Cameras.

Whats more, in desktop mode, NO programs can see them. Only in Metro are the cameras seen by Skype and the "camera" app.

It goes on. Although the drivers DO make the cameras work, if i install BOTH drivers, the rear camera doesnt show up anymore, and it is superseded by the Front camera.

Also, in any of the apps that saw the camera, the drop down menus only list ONE camera.

If i then uninstall ONE of the cameras in the Device manager, the Rear camera comes back to life (naturally overtaking the front camera). But i havent been able to get both cameras to work together, since im sure your supposed to have the option to cycle between the two.

And yet ANOTHER problem is that the drivers might make the camera REGISTER, but they dont even make the camera function correctly, since the image is VERY VERY low exposed, (the exposure settings in the camera App, dont do anything) and the image is a Wierd GREEN tint.

I even tried to extract the drivers from the "Install.wim" on the recovery partition, but that .wim doesnt seem to work with ANYTHING:

Not ImageX/Gimagex (wont mount because it claims i dont have the space),

or 7zip (cant be opened as an archive),

or any other applications i tried that are supposed to handle .wim files.

I guess my question is, does anyone have the same cameras in their VOYO A1 Mini as i do? the: OVTI2680 's And if so, do they have working drivers?
[Windows 8 General] reggiexp:
yeah i probaly should buy it. cause a tablet without touchscreen is even more usless.. first i wanted to sell it but i bought to many things already. so i will lose to much. its nice but it lacks things. the screen is way to bright on 0% for late night playing in bed...
[Windows 8 General] trevor68:
Ok, feeling like a total numpty here but I cannot for the life of me get my Voyo Mini (F Series) to boot from USB, at all. On my old PendoPad I used to just select UEFI: Removable Device and away it went.

On this Voyo it ignores UEFI:Removable device and just loads windows normally. A look in the BIOS reveals only 2 boot options, which seems odd as the Pendo had 4. I can see UEFI:Shell, or Windows Boot manager, thats it.

I have tried disabling Secure Boot, and setting UEFI:Shell as the first boot priority, all that does is load the shell command prompt. I'm sure its just something silly in the BIOS settings, but given I can see its easy to stuff the settings would like to know where to look, or if anyone else has had this issue?

Other than this problem driving me a little bonkers the pad itself is nice, pretty pleased with it for $150AUD from BangGood.
[Windows 8 General] reggiexp:
still nobody knows a fix about the sudden dead? just within minuts of turning off the screen the backlight won't turn back on..

btw what drivers do you guys have activated in bios? im trying to figure out with one will be for the dy08017 v2 touchscreen. i just home that the euro will just get some value. cause 15dollar = alors 15euro. but i think thats lost time. as for now my tablet is still as useless as when i first bought it. its to bright for the night (or is there a app to dimm the screen more?) or a hack?
[Windows 8 General] ricxgp:
Voyo has released a dual boot bios, but only for 5V2A model, what are the diferences between 9V2A and 5V2A, maybe the processor, 5V for F, 9V for D... ? I have 9V version and the processor is D.

http://www.myvoyo.com/xiazai/pingban/voyo_a1mini/
[Windows 8 General] jockyw2001:
Did you manage to download it?

You can't use that bios on your 9V2A model, which has the D cpu and other power management and charger electronics.
[Windows 8 General] roy8846:
Hmmm I have F version 5v, does this boot Android?

Haven't really messed with my Voyo yet
[Windows 8 General] reggiexp:
dualboot would be fun yeah.

maybe that will motivate me to repair the tablet :) i'm still to lazy to order a new touchscreen (cause i'm not 100% sure if it realy will work... and i have no one that can confirm) most think so. for the rest repairing seems okay. if i can get the touchscreen of the frame :)
[Windows 8 General] ricxgp:
I had to use Jdownloader.
[Windows 8 General] jockyw2001:
Dual-boot is already possible with the current A1 Mini "bios". When I power on my Voyo I can choose between Windows 8 (default), Android (android-x86) and Linux (Fedlet, a Fedora tablet version). I use the 'volume -' button to cycle through the menu options and the 'volume +' button to start the selection.
[Windows 8 General] jockyw2001:
Thank you. I'm now downloading the package. The problem is that filenames and documentation are all in chinese.

Is there any chinese forum user who can translate the attached Word file?
[Windows 8 General] reggiexp:
hum wierd. me its direct windows nothing els as option.

Battery drain

What do you mean "go offline"; I understand your suggestion to mute the audio but "go offline"; You mean in flight mode;
[Windows 8 General] reggiexp:
That would be cool.

Btw what version of android you van use?

---------- Post added at 01:30 AM ---------- Previous post was at 01:29 AM ----------

Yeah i will try the mute option.
[Windows 8 General] oile:
Flight mode yes :) muting the audio avoid a realtek driver bug
[Windows 8 General] madduckuk:
If you could do that it would be amazing, things have gone a bit quiet with the old A1 Mini now, so getting dual boot going (or tri boot even, as you say) would be a great last hurrah before nobody talks about them again. I'm sure a hell of a lot of people would like to get android on there.

Don't think I have even seen an English BIOS flashing guide yet, that would be a great help.
[Windows 8 General] reggiexp:
it there no app or thing that cuts the wifi when you turn screen off. cause i won't think of turning flight mode on every time

[Windows 8 General] antivizio:
Dual boot update failed

Hi, I flashed the new BIOS in order to have the Dual Boot and then the lcd panel is messed up, like the resolution is wrong but it's not bricked because the HDMI output works fine. So maybe it's necessary to change anything in the BIOS but I do not know what. Any ideas? Just in case you ask, I have the 5v2A version bought last December.
[Windows 8 General] paul89rulez:
mmm can you be more specific?
[Windows 8 General] antivizio:
Sure, my device is a Winpad A1 Mini - Serial number: A10220140605 DC5V2A.

I followed the instructions to install the new dual bios. An USB stick formatted as NTFS and the files from the zip copied directly to the root.

Then I entered into the EFI Shell and run the following command:

fpt32.efi -f I8080V6MIPI_V1.7.0_R008_FT_OV2680x2_LogoDefault_LCD800x1280_20150205.bin

The process finished correctly (FPT Operation Passed), but after booting the screen does not show correctly the image, like it has a different resolution that can't be used in this LCD Panel. Then I connected the device to an external monitor through the HDMI output and it works fine. The problem is that I don't know how to make the screen to work properly, maybe this new BIOS is for a different model of processor, I don't if this is Z3735D or Z3735F, but in the website just indicates that the update is for the 5v2A version.
[Windows 8 General] jockyw2001:
It looks like you must configure the correct lcd panel in the new bios. Take a look at the screenshots of my "F"-model bios settings that I've posted in this thread and try them out by setting them in your bios.

EDIT: in particular image 4 of stock bios settings 3 lists the lcd panel brand.
[Windows 8 General] OttaGaudencio:
Is there anywhere where I can find the instructions in English? I translated the Chinese text of the files in voyo site in Google translator, but it's kinda messed up and I don't use to do these type of proceedings, so I don't understand much about it and I don't wanna mess up the device, so anyone?
[Windows 8 General] digimon04:
Since nobody posts the instruction in English yet, I try to translate the Chinese instruction into English. READ CAREFULLY. I haven't flashed this new bios and dual system to my voyo a1 mini. I am not responsible for any consequence arising from the flashing process and/or following this instruction. I am also not familiar with system flashing. I may not able to answer any of those question. Many people have reported that the Windows can't be activated, touch screen not working after flashing or even halt during flashing. Use at your own risk.

This dual boot firmware is only applicable to 5V2A hardware variant of A1 Mini.

Pre-requisite:

5V2A A1 mini, USB hub, Keyboard, 3 x USB thumb drive

Format a USB thumb drive as FAT32 and name it as UUI

Copy the Android related files to the root of the above drive

Format a USB thumb drive (8GB or above) as NTFS and name it as WINPE

Move the windows related files to the root of the drive

Format a USB thumb drive as NTFS and copy the new bios files to the root of it.

(if the device can't read it, format it to FAT32 and try again)

1. flash new bios

Connect the USB hub to A1 mini and plug in the keyboard and the USB thumb drive containing the new bios files. Power on the device and press DEL to enter into BIOS.

Navigate to "Save@Exit", and then choose "Launch EFI shell from filesystem device"

After entering shell, type FS?: and then press ENTER

( ? stand for a numeric character. It depends where your USB drive resides, for example, if your USB drive is at FS4, you type FS4: You can always try between FS0 and FS4 )

Then type dir and then press ENTER

Type fpt32.efi -f and choose the only .bin file and press ENTER

Type fpt64.efi -f and choose the only .bin file and press ENTER

Type exit and press ENTER

When you return to BIOS, choose "save changes and reset"

2. install android

Plug UUI drive to USB hub. Press DEL to enter into BIOS.

Navigate to "Save@Exit", and then choose "Launch EFI shell from filesystem device"

Wait until it finishs.

3. install windows

Plug WINPE drive and keyboard to the USB hub. Power on A1 mini by pressing Power key and Vol+ key. Navigate to Windows icon and press ENTER. Windows will be installed accordingly. When the process completes, the device will boot into system.

The whole process finishes.

Hi, I have checked every option and it's all exactly like your BIOS configuration. I think the dual boot BIOS is not compatible with all the devices even if they're 5V2A versions. Now I will try to flash the original BIOS and hopefully it works again... but it won't be that easy, now I have a 64bits UEFI Shell and probably it will show a message stating:

"image type ia32 is not supported by this x64 shell"

I bought mine while I was in China directly from the manufacturer, I don't know any trusty seller in Aliexpress but check the reviews/ratings of each one to make your decision.

---------- Post added at 10:26 AM ---------- Previous post was at 10:03 AM ----------

I contacted with Voyo, their technical department and they sent me the following file with several original BIOS roms:

https ://mega.co.nz/#!jk1XWK5T!3fC1YSBMyGty5ilxGyEV-R50BhDeX3UeCflEkvG3icM

I will try with I8080V6MIPI_V1.6.9_R008_FT_HM2056x2_NoLogo20150113.bin and lets see...

EDIT: But I don't know if the ESP is separated from BIOS, if so I would appreciate it :)
[Windows 8 General] jockyw2001:
Could Voyo technical support also help you with the dual-boot bios problems?

In their dual -boot package there is the bios version I8080V6MIPI_V1.7.0_R008_FT_OV2680x2.................................20150205.bin

OV2680 and HM2056 are camera modules. So you may want to check with Voyo if each BIOS file supports just a specific camera.

I will send you a PM later on with the ESP download link.
[Windows 8 General] reggiexp:
so you see we need to disconect both cameras so it stops going in to a coma?
[Windows 8 General] paul89rulez:
i did that, but maybe with the correct driver you can ignore this hardware mod.
[Windows 8 General] reggiexp:
hum i could try to disable the camera drivers. but im way to lazy for that :)))

anyone try it? no problem?
[Windows 8 General] hung2k:
As digimon04 mention,

"Many people have reported that the Windows can't be activated, touch screen not working after flashing or even halt during flashing. Use at your own risk."

For me i can finish the flashing dual system comletely without any problem by following the official instruction
[Windows 8 General] jockyw2001:
I also installed Voyo's dual-boot system. Before I did that I made a full backup with Macrium Reflect (free edition).

The dual-boot uefi firmware ("bios") is a big improvement, because it now supports touchscreen. If you're not interested in installing Android and reinstalling Windows, then you may consider to install only the new uefi firmware. I did try this myself before I installed the dual-boot sw and my already installed Windows booted without problems.

The kitkat android version looks nice and clean at first sight, but unfortunately play store won't connect and trying to fix this is probably not trivial, because there is no developer option for enabling usb debugging. Windows installed without any problems, but can't be activated. The error code is 0XC004C003 "The activation server determined the specified product key has been blocked" (!!). I tried activation via telephone, but the activation ID could not be recognized and I then hung up. I also looked for the product key data in the MSDM area of the ACPI table, but the MSDM is not present. Unfortunately I didn't check if the MSDM area was present before I installed the dual-boot system. I fear the product key is blacklisted or that the installation procedure somehow erased the key from the firmware.

I just tried with Macrium Reflect to overwrite the new Windows partition with the backup of my previous Windows partition, but it didn't work and I got an error something like this: The application or operating system couldn't be loaded because a required file is missing or contains errors. File: \Windows\system32\winload.efi Error code: 0xc0000225. Later I will try the "bootrec" utility to fix this.

So the dual-boot system looked promising in the beginning, but fttb it caused a pile of problems which hopefully can be solved soon.

EDIT 1: The battery meter is stuck at 7% although it is connected to the charger all the time. I think it is same problem as Teclast X80H users reported here. I will try out that fix.

EDIT 2: I did a full restore of my original system backup which includes 4 partitions (EFI ESP, unformatted 128MB, Windows, Recovery) and could boot up my originally installed Windows without problems and it is actually still activated! I looked up the productkey with Nirsoft Produkey utility and will try out the same key after restoring the entire dual-boot drive.

EDIT 3: The battery charge problem was solved after switching off and fully charging it overnight.
[Windows 8 General] digimon04:
The installation of the new uefi bios does erase the Windows product key. Therefore, manufacturer has warn users that the tablet might lose activation after the flash. I'm glad that you have a full system backup.

Please report back soon if you could use your original key to activate the Windows. Also, would you mind posting your flashing procedure? I am still confused with the new uefi bios flash process. Thanks.
[Windows 8 General] jockyw2001:
Luckily I could activate the dual-boot Windows with the product key of the originally installed Windows (XXXX-XXXX-XXXX-XXXX-8TXKG). The product key data is not stored in uefi firmware, so there are no MSDM/SLIC tables in the ACPI DSDT. I suspect all Voyo users have the same product key ending with 8TXKG. I recommend to use Windows 9 Product Key Viewer v1.5.0 by Woot332 to back up the key and activation data before you start to install the dual boot system or any other OS. You should also make a full backup of the built-in drive with Macrium Reflect.

I flashed the "bios" (it should be called uefi firmware) as per your translated instructions. Before I started I took photos of all my current bios settings. I had disabled the "secure boot" setting, but probably that setting doesn't matter. The new bios is actually a hybrid firmware, it supports both 32-bit and 64-bit modes. In Android mode it boots up in 64-bit mode and in Windows mode it boots in 32-bit mode. That is pretty cool for Linux and Android hackers like myself.

Now that Windows is working reliably I will start to spend some time to solve the Play Store problem in Android. Once that is solved it will makethe Voyo a pretty useful tablet.

EDIT: I managed to fix the problems with Google Play Store. Now trying to root the device. Normally not too difficult, but there is the problem that USB debug isn't enabled. We'll see..
[Windows 8 General] digimon04:
Amazing! But how can you solve Play store issue?
[Windows 8 General] jockyw2001:

USB issue

So now my Voyo A1 Mini is a nice dual-boot tablet, Android Play Store works and also Windows works fine and is activated. However, there seems to be a problem with the usb connection between Voyo and PC. Using a standard usb cable my PC does not recognize the Voyo. For example I would like to transfer files between Voyo and PC and also I like to root Android and need a working usb connection for that. Does anyone have the same issues and is there a solution?

EDIT: I manually rooted Android and can now try to figure out how to enable usb connectivity etc.
[Windows 8 General] maxxxy:
sorry

where can i find the tutorial or guide for install dual boot (win/android) on my voyo???

thank's
[Windows 8 General] jockyw2001:
here you go
[Windows 8 General] DarkAMD:
Which Method did you use to do that?
[Windows 8 General] jockyw2001:
In linux I unpacked, modified and repacked system.img and boot.img. ADB via wifi now also works fine.

What doesn't work is filetransfer (MTP) and ADB via usb. It seems to be a firmware issue which only supports OTG mode and device classes for being a usb slave are missing. There are similar baytrail tablets, e.g. Teclast and Pipo, where at least ADB via usb works fine. If anyone has a better explanation please let us know.

Another interesting feature called "Intel DNX mode" doesn't work properly on the Voyo, that feature works fine with some Teclast and Pipo tablets. You can see what I mean by powering on while keep pressing both Vol- and Vol+ buttons. After a while you see "Entering dnx mode. Waiting for fastboot command" for less than a second. It should stay in that mode and allow for recovery with fastboot via usb. Another sign that usb with tablet in slave mode is not supported. I will check later if I can use droidboot with a ethernet-usb dongle.

Anyway, I can highly recommend the dual boot configuration as it is now a much more useful tablet during travels.

PS: it seems the dual-boot feature is no longer linked on the Voyo web site (http://www.myvoyo.com/xiazai/pingban/voyo_a1mini/). The original news was dated March 19th 2015

EDIT: Could it be possible the usb data line (D+) does not have a pull-up resistor, in which case a PC host device can never detect the Voyo as slave device?? See this web site for a simple explanation of usb principles. Can someone who opened the Voyo confirm this? I didn't measure a voltage on D+ or D- when I plug in a USB cable (tried with and without OTG adapter).
