I really just had a visual look on the daughter board and haven't removed it., but yeah, i think it needs the SIM slot only.

I charge the tablet when in windows 32bit and when its off. I honestly haven't tried charging it on its Android OS (64bit).

I charge it using the mains charger with a micro usb cable.
[Windows 8 General] jockyw2001:
I think your 6.0 board has a USB375X ic which includes charger detection and rapidcharging via USB. I think EMDOOR dropped that ic with later board versions. There is a firmware setting for that chip in advanced-pmic configuration called USB MUX (FSA/SMSC3750) ON. It is set to Enabled in my firmware. I should take some detailed photos of my v6.1 motherboard and 3g-module board some time.

EDIT: found some mainboard pics made by our russian friends on the 4pda site. There is a AXP288 pmic which can support 5v power supply via dedicated jack or usb. This can be seen here: http://www.sharkscove.org/wp-content/uploads/2014/07/Sharks-Cove-Technical-Specifications.pdf

I suspect on the v6.1 main board there is a trace and a diode missing which unfortunately prevents charging via usb. I found a mod for another tablet which I think can also be done on a mainboard with v6.1:

[Windows 8 General] Skanob:
Could be. I haven't had a good look of the motherboard (removed it from the tablet).

I'm more interested on changing the 0.7mm*2.5mm female DC-IN Socket to a Micro USB female socket. It seems a lot of people are having problems with it. Have you thought about this? I'm really not too good on my soldering skills.
[Windows 8 General] speedtouch2006:
I have the same problem as well, the tablet switches itself off at random times. The thing is I installed Windows from scratch, so I'm wondering if the same problem exists for those using the official image?
[Windows 8 General] sikica133:
try disabling hibernation altogether. after that, it never happened again, at least that's my experience
[Windows 8 General] speedtouch2006:
Thank you, did a powercfg /h off, hope that fixes it. Will report back if this fixes things

EDIT: No reboots so far for quite a while now, this must be a fix. Thanks!

[Windows 8 General] bravoo89:
hello dani.what do you mean?should i try with a diffrent otg cable?and if so could you please tell me the steps to recover the bios please
[Windows 8 General] dani7710:
Yes whit different otg cable work?

Sorry no idea how to recovery the bios.
[Windows 8 General] bravoo89:
yeah it works with most of the otg cables.maybe your otg cable is broken.u can find some on ebay for less than 5 bucks
[Windows 8 General] paul89rulez:
so, what about the recovery (android) for the tab?
[Windows 8 General] Skanob:
Has anyone had the same problem that I'm currently experiencing?

The tablet doesn't seem to detect the HDMI that I cannot, but my monitor can. Monitor will say cable detected but no signal.

Tried it on the Android version, still the same. Could it be a UEFI setting/s that needs to be changed? Driver perhaps?

I'm currently using all of the drivers extracted from the recovery wim file from their official recovery guide, to a Windows 8.1 Pro x86 version.
[Windows 8 General] reggiexp:
yeah received my touchscreen and it works :))

will try to get of the old touchscreen and put the new one on tomorow :))
[Windows 8 General] paul89rulez:
i have this problem too :|

I have read somewhere that uninstalling le Intel graphics driver fixed it for them. Didn't work for mine.

Anyone else having the problem or fixed it?

[YOUTUBE]watch?v=m32VCCD9794[/YOUTUBE]

It's a video I recorded to report to banggood of the problem
[Windows 8 General] jockyw2001:
Hdmi already works at boot time. Try power off the voyo, connect hdmi and power on. Note that it outputs 1920x1080p with default rate of 60hz. Also try again after reset bios to defaults.
[Windows 8 General] Skanob:
Tried both, didn't work. Any ideas?

Weird why the monitor can detect that the HDMI cable is connected/plugged in (receiving signal of connection) but not receiving any signal (image) from the transmitter (the tablet).

When I go to Screen Resolution and press the Detect Displays, the tablet detects that there is another output display, and this is even without connecting any hdmi cable, then I can choose if to connect using Mobile HD Display or VGA. Did not work at all. Played around with the settings on it. I can even have a max of 3 displays, but non of the non-main display (display 1, the tablet screen) worked. Even if I try to make the other 2 displays to be the main display.

Any ideas?

Edit:

Currently finishing my WIMboot Image of Windows 10 Pro Build 10130. Had to VM install Win 10 to add the drivers on the image. Should be done in 20 mins installed on the tablet.
[Windows 8 General] jockyw2001:
I have a similar issue when I connect my settop box with my Samsung plasma tv. The TV senses a source is connected but gives a bad signal error message. When I connect the settop to a Samsung LED tv it works fine. Samsung tech support told me the settop likely sends a bad signal, but that it sometimes may help to reset the HDMI configuration in the TV service menu, try another HDMI input port or try another cable with better. So far I haven't tried these suggestions.

Cool! That reminds me I should still put up my rooted Android image. Will do that next weekend.
[Windows 8 General] Skanob:
After a few hours of testing Windows 10, I've decided to reflash my Win 8 wimboot image.

I do like Windows 10's style and look. Except the global taskbar even with tablet mode on. I guess I already am fond of Win 8.1's "tablet mode".

Tablet mode I reckon is half-way finished. Very buggy.

But the desktop mode works perfect.

Anyways, I've already received a notif from Microsoft about the free windows 10 upgrade. Already got me a reservation. Just need to have one for the tablet.

Going back to the hdmi, is yours working? win 10 is the same but worst? It does not detect the other displays anymore. And still cannot detect HDMI.

I'll reset the uefi before flashing my win 8.1
[Windows 8 General] jockyw2001:
As I wrote before, hdmi works fine for me from the moment I power on. Works in bios, windows and android. Resolution is 1080p.
[Windows 8 General] Skanob:
Must have missed it. I wonder if it is hardware issue already. Flashing win 8.1 wimboot.

I saw that you know here many.

I will buy this tablet. Now I heared that I can also install Android.

Is this then dualboot or how does this work?

I want to use Windows and Android.
[Windows 8 General] Pipes1977:
I know it sounds a little over simple, but I had the same problem with my A1 mini, I had to try 3 different HDMI cables, but magically one worked as would normally. All the others had issues with displaying on my LG TV.
[Windows 8 General] adeetya4:
i have usb disabled in uefi . how can i reset the bios .please help i am in big trouble.
[Windows 8 General] teh_orph:
Howdy.

I'd also like to use the dual boot flash, however also get the display corruption. Double-checking my BIOS settings against the screenshots in this threads and my photographs gave nothing. I've just gotta flash back to my backup :(

That other fella who had that issue: is that firmware (which was on mega) still floating around anywhere? I've tried contacting Voyo but I am doubting I'll get a reply. One of the email addresses listed on the their contact page bounced!

Also, with the original BIOS you can clearly boot Windows-based 32-bit UEFI USB sticks. Can I use this to boot other 32-bit UEFI stuff or does it have to be Windows? (secure boot is off)
[Windows 8 General] Skanob:
You are screwed. There is no way for you to reset the bios/UEFI only on the UEFI screen. Please refrain from using BIOS as these doesn't use BIOS anymore. they use UEFI now. There is no switch/jumper to clear your settings for these. Someone, who screwed is as well, mentioned that you need a IC programmer to connect directly to the UEFI ROM to reset, in which I don't know how to do.

Well this is a really good experimental device for me. I'll be returning mine for the issues of the HDMI and DC not working. I'll be getting a Pipo W4S for my wife, and Pipo W3F for me.
[Windows 8 General] PsyCLown89:
Hi all,

So I have been having some battery issues with my tab - I will be watching something from Plex or browsing the web after fully charging my tablet and then suddenly the tablet will just die and turn black. If I try and switch it back on straight away nothing happens, I need to wait around 15 seconds and only then will it turn back on.

Once it is back on the battery % has dropped quite a bit although I can still continue to use it for a long period of time. It seems to happen twice while running the battery from full to flat.

Any ideas why or how to fix it?
[Windows 8 General] sikica133:
turn off the hibernation & try it that way
[Windows 8 General] PsyCLown89:
I thought I had done this, but seems not. Turned it off last night, so fingers crossed this helps! :D
[Windows 8 General] Zuaro:

[Windows 8 General] kc12:
Hi. Is it possible to turn usb debugging on in build.prop prior to flashing android UUI?
[Windows 8 General] PsyCLown89:
So thought it was working but noticed and confirmed that after a full charge, I will use it for a bit then around 80% I will be busy with something and suddenly it will randomly be "shutting down" and I then have to turn it back on and it is generally fine until the battery is flat.

Any ideas why it might be doing this? I wonder if it has built in thermal protection which might be triggering it? Or what else could it be? Faulty battery?

Unfortunately I cannot set it so that even when the battery level is critical it "does nothing", it can only be set to "shut down".

Hi

You have 2 options to enter bios without usb, i uploaded photo for this.

1, if you have dualboot tablet, the screen bottom left have (yellow text) bios option.

2, on bootscreen(american megatrends) make fast touches near the text message to call the virtual mini keyboard. You can hit on this the escape and enter the bios(you need do fast,really fast)

And i have question for others.

Any can use google playstore somehow? Its say no connection, but other google app working.

And i cant connect to pc in android mode with usb cable, any solution for this?
[Windows 8 General] PsyCLown89:

I've given up hope on getting anything useful done on this tablet though

[Windows 8 General] oile:
Good to see you on xiaomi.eu and here too xD beautiful phone and good tablet!

However, the 5v2A version is chinese market version and image 4.92 GB is in Chinese.

The 9v2A version is the international version, and the image is in English.

Don't know why this volt choice but a Chinese tablet all in English is so good!

The touch is not nearly as sensitive as the vido w8c
[Windows 8 General] paul89rulez:
I have some other versions, I will upload it when I finish work
[Windows 8 General] Buggster:
Maybe there the 5v2A difference is for the f version.. ? Just guessing.

I have just ordered an F version :)

Any reason to update at all, anyone notice any differences(and which should I install)

Will be keeping an eye on this thread :D

Battery life

Hello! I'm interested in this device's battery life as well! And what are the option to charge it via a powerbank? Would it just be a microusb powerbank or are there any alternatives?

- I'm almost buying this haha!
[Windows 8 General] Buggster:
Don't expect battery life of an 500$ device. But all in all battery life is good.

I also have an venue 8 pro and on full load it's battery is empty in 3 to 3.5 hours.

That's full cpu load, 100%.

In normal use, watching movies and surfing I get max 6 hours on the voyo.

Continuous use. Depending on the brightness. Stand by time is great. Around

2 weeks I think.

If you have the 9v one it will charge fast. If you have an powerbank with adapters

best you use the 2mm vs micro usb, thats also faster.
[Windows 8 General] ferdyfist:
Thanks a lot for the answer!

The 9v one you say? I'm a bit confused then, which version is this? http://www.coolicool.com/voyo-winpad-a1-mini-80-inch-1280-800-screen-tablet-pc-intel-atom-z3735d-13-18-ghz-quad-core-windo-g-33708

And is there another version I should buy instead?
[Windows 8 General] Buggster:
D version uses 9V/2A the F version uses 5V/1A.
[Windows 8 General] ferdyfist:
Alright sweet! So just a powerbank with a 2mm?
[Windows 8 General] Buggster:
I think it's 2.5mm, not sure, can't check now. But an power bank with a set .mm adapters

will probably be fine.

on my voyo a1

seems like my voyo gonna get it first my chuwi vi10 has also the thing but couldnt reserve it :) ot what ever

will see i will try first on my voyo :) if once i may download it :( and 4gb gonna take me like 2-4H......
[Windows 8 General] PsyCLown89:
Been running Win 10 on my PC for a while. I reserved Win 10 on my Voyo a while ago as well as on my work laptop.

I was able to upgrade my work laptop but not my Voyo so downloaded the 10240 x86 ISO and did the upgrade on my Voyo. So far I am loving it!!

Tablet mode is nifty. Seems to run alright.
[Windows 8 General] grayfone:
just installed win 10 final on my Voyo A1 mini (5V/2A edition, single boot windows flashed to dual boot, no problems), updating from the 8.1u1 with bing originally installed.

Everything worked fine EXCEPT the auto-screen rotation. Does it work on yours? If yes, did you do anything special to activate it? Any clue to set me in the right direction would be very helpful.

EDIT: Looks like deactivating the sensors and reactivating them, checking the sensor service on automatic and rebooting the tablet did the trick

If anyone else has question on Win10 on this tab, ask away, I can test stuff for you guys on it.
[Windows 8 General] Aulaxim:
I tried deactivating the sensor from Device Manager and then set the service on automatic, rebooted but screen rotation is still not working. Did you do anything more?
[Windows 8 General] grayfone:
Well, to be precise I did something else.

I did install the KXaccel drivers v1.0.13.20, for windows 8 (sorry, but I can't link them cause of my insuffcient post count). Since those didn't really had any effect, I did rollback to the original (installed by win10 itself) drivers and did reboot. After rebooting, the tickable checkbox "auto-rotation" in the screen options did appear.

At the moment I still am having the rotation order messed up, but that's probably just a matter of setting the correct data in regedit. Fiddling with it right now ;)

EDIT: Fixed the messed up rotation order, if anyone has the same problem on the Voyo, you need to modify a registry key. You can copy-paste the enclosed text, save it as FixRotation.reg and import it in your own register using regedit or simply double clicking it (might need administrative permissions). It needs a reboot to take effect.

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\ROOT\SENSOR\0000\Device Parameters\kxfusion]
"ACPI\\SMO8500\\1-0"="{CDA4B5F8-53B4-4E7C-8A73-0D69852FBEBA}"
"Orientation"=hex:01,01,00,00,01,01,02

P.S. Don't know if it makes any difference whatsover, but I have the following updates installed: KB3074683, KB3074686 and KB3074678
[Windows 8 General] Aulaxim:
I installed the drivers and when I rebooted I had screen rotation but it was out of order too. I modified the registry key and now it's working. Thank you!
[Windows 8 General] maubarra:
I updated my Voyo A1 mini but I can't get screen rotation to work. I tried your advices. Disable it. Enable it. Update the driver. Rollback, rebooted. Nothing works. I still don't get the auto-rotate. Maybe my driver is wrong. Can some one share yours?
[Windows 8 General] dani7710:
Im istalled win10 with Microsoft tool. iso. Im whitout clean data and app. Rotation works perfect. 18gb free space, win10 use 9,8gb. It's so much space?

if I want a clean install I will need only the driver of the rotation?

Inviato dal mio GT-I9505 utilizzando Tapatalk
[Windows 8 General] Aulaxim:
I didn't roll back, I just installed the drivers and then rebooted. I used the one from here: mediafire . com/download/811sf5254o23g88/W3F%E9%A9%B1%E5%8A%A8.rar
[Windows 8 General] maubarra:
Okay, installed the driver and rotation works but is messed up. Applied the registry changes but is still messed up. I'm not sure what is wrong, maybe I need to use other values in the registry?

I'm not sure, I just copied what grayfone posted and it worked after a reboot.

Can someone please confirm to me if they got a Windows 10 reservation using a WIMBoot Windows 8.1 on their Voyo A1 Mini?

Currently running insider program. Would definitely be wanting to get RTM.
[Windows 8 General] jockyw2001:
I eventually got the reservation in my w8.1 WIMBoot (see my thread in this forum). However, upgrading failed. I then restored my normal non-WIMBoot partition and could upgrade without any problems. You actually don't need the reservation, just run the w10 mediacreationtool and either run "upgrade this PC" or create a usb pen drive with the w10 home edition and run setup.exe from it to do the upgrade. W10 will activate automatically, no need to enter your productkey during the process. The w10 productkey will be different from the w8.1 key and apparently the activation servers notice it is an upgrade nd store a hw signature of the tablet.
[Windows 8 General] grayfone:
Try changing the Orientation key to:

"Orientation"=hex:01,01,01,01,00,00,02

and reboot.

if that doesn't work the correct way, but you see a different order after the mod, you gotta play with the values until you get the rotation right for the driver version you have installed.

I don't have any official information about the format of that registry key so it's all trial and error, alas :crying:
[Windows 8 General] ansafrahim:
Do you mind uploading the roation fix to a different server, i am going crazy here trying to fix it. Used numerous registry fixes but didnt work. My tablet is Voyo A1 mini as well.

Mandatory to install kionix_1.0.14.2_2014.08.11 to fix rotation bug.
[Windows 8 General] eltrot1979:
I've successfully managed to get Win 10 installed on my tabs and fully activated. A couple of issues I am having are that if I select reboot from the shutdown menu windows shuts down and the white light led light comes on, but the device never reboots. When in this condition I have to hold the power button down until the device powers off and the power it up again.

Another issue I have was actually present in Win 8 as well. On one of my tablets the volume hardware button does not function correctly - both the volume up and down buttons will act in the same direction until volume is at the min or max and, at which point the action will reverse! Very annoying! Any ideas if this is a driver issue or a hardware problem?

Thanks
