Problem solved. My mistake was that i tried to change quite some settings at the bios setup. Some of them were harmless like memory allocation for GPU, but it seems that the main cause was that i changed some settings for USB OTG, something like that. Anyway, the solution was restore default settings for the bios, reinstalled using january's drivers and finally installing the most update graphics drivers from Intel site. Now all the drivers are installed, both cameras are fully working and now i'm using windows 8.1 pro x86 completely updated. First thing i noticed is that there's some considerable performance improvement replacing WIMBOOT with the usual windows installation, since there's no compressing involved. The only drawback is how much of storage it takes. Right now windows can use something around 30.5gb, and with windows update, eset smart security and some other programs installed it's taking almost half of the storage space. Now here's some lesson learned: If you're going to change some options at bios setup at least try only once each time.

OTC and Chaging

I've been unable to get my Chuwi to charge while using any USB device.

I have two OTG hubs that works with my Nexus 10 tablet, but I've tried everything I can think and can't get OTG to work on the Vi8.

I have a special HID device I need to connect, so I really need to get OTG working..

I've tried all the BIOS settings I can think of (see attachment), but nothing works it won't charge and recognize USB devices, not in windows, not in Android.

Any advice or suggestions, please???

I am quite a newbie. Do you know

-if there is a way to set bios to 'factory defaults'?

those I had when I received the tablet.

- is there a way to RESET Windows to 'factory defaults" as well? (or even reset the whole tablet)

-is Windows registered or 'non authentical" ? (and if I loose the eventual registration if I reinstall windows)

There have been reports of it not holding charge when left in standby for 24 hours.

Can anyone comment further and if so have they retained dual boot functionality or reinstalled Windows?
[Device Reviews and Information] tiagao_extremo:
Don't worry about being a "newbie". Everyone starts from the same place. I just received my chuwi vi8 a couple of weeks ago. Since there's no international support forum this is the place where we can discuss it.

1 - You can restore the bios setup to the factory defaults. It's just like any other motherboard. The last option, i don't remember exactly but you will see it there, restore optimal defaults, something like this.

2 - I can't say for android, in fact as soon as i received this tablet first thing i did was delete the android partition and increment windows partition size, but you can use the windows recovery. I guess you need to power on your device holding power and volume + until you see the options, if i'm not mistaken.

3 - Yes, all these chinese tablets with windows have in fact an original windows 8.1 with bing key. It was some kind of agreement from microsoft in which they would grant a license for tablets until 10'' screen. Even if you make a full formating and use windows 8.1 with bing image it will automatically recognize your license. But you can't use this key with windows 8.1 pro for example.

Video stutter

Hi everyone. Thanks for all of your tips and tricks for this tablet. I have got mine two weeks ago. Everything works perfectly except for one thing. For unknown reasons when I use my tv as a screen and I try to play any video (avi mkv dvdrip 720p 1080p) through a media player (kmplayer vlc or mdeia player classic) it starts to stutter after some time. It doesn't matter where the vieo is played from (external hard drive sd card or internal storage) it starts stuttering. I reinstalled windows and it does the same thing except now it only stutters when playing in fullscreen. Any suggestions what could be the solution? I am clueless and desperate now. Thanks for the help in advance.

Did you tried updating the video driver from intel's site?
[Device Reviews and Information] laxikahun:
Thank you for your fast reply! Yes that was my first step after reinstalling win8. But unfortunately it didn't change a thing. Seems that if I only play the videos on the tablet the stuttering does not appear. I only tried this once and then there was no problem with video playback.
[Device Reviews and Information] tiagao_extremo:
Hi Laxikahun, i tried to play some videos at my tv through HDMI. It seems that this device can't power an external HDD and using hdmi at the same time. I connected my hd using the otg cable included. It started just fine, but after some minutes media player classic couldn't play the video any longer, which was rather strange. Today i used my usb hub, this one:

http://www.dx.com/p/s-k01-usb-2-0-3-port-hub-smart-phone-otg-charger-white-311539.html

It does works. The main issue was that it discharges the battery way too fast. After one hour it took almost 50% of battery, but it played a 1920x1080 video file just fine with no issues. I bought this another hub:

http://pt.aliexpress.com/item/4-Por...ndroid-Tablet-Smartphone-YKS/32341401782.html

Some other sites says that it works with the chuwi and it can charge and use otg at the same time. It still hadn't arrived, but i hope it works, since one of my main objectives for this tablet would be able to play some videos at my tv.
[Device Reviews and Information] laxikahun:
I am using a an external hdd with a power supply and even that is connected to an otg charger hub so battery drain was not the issue. The graphics driver was the culprit. I completely uninstalled it then used intel driver update utility and it works like a charm with media player classic and kodi. Still not working with kmplayer but it doesn't matter as I like kodi much much more!

Hi SDA_Lord, are the two partitions mounted alright for you? Like you did, I split my 64GB MicroSD half/half. First partition is FAT32 as primary and the second one is EXT4 as primary. The second partition (EXT4) is mounted fine and I can use Link2SD but it doesn't seem that the first partition (FAT32) is mounted at all. I am wondering if there any step that I have missed. Thank you.

EDIT: One more thing, the FAT32 partition doesn't show up on Windows 8.1 either.
[Device Reviews and Information] SDA_Lord:
I can see both partitions is the ES File Explorer Android app. Cannot see the FAT32 partition in Windows 8.

Hi everyone. So, my hub finally arrived, and i'm having the same problem as laxikahun. I bought this hub at aliexpress because according to many people it would work with the chuwi vi8, allowing it to use peripherals and charge at the same time:

I connected and it works. My issue is when i'm playing video files, since this was one of my main objectives for this device. I'm using an external HDD and after a couple of minutes the video starts to stutters, really bad. I'm trying to play some videos with average quality, 1920x1080, around 1.5 ~ 2gb, which i was sure this tablet could handle. Same thing happened when using media player classic from k-lite codec or vlc player. I copied the same video to the internal memory and it plays just fine. First thing i noticed is that when i'm playing from internal memory the cpu goes around 55-60% usage, but when playing from the HDD it goes to 100% in a few seconds. Any help would be greatly appreciated.

Change some setting in k-lite. First you have to use gpu acceleration. There are some other settings which I cannot remember now but will check it for you once I have some time. Also use kodi for movies, I found that to be the most cpu friendly media player, smooth too. Do not use any other program while playing a video that will save some cpu and ram power. Always plug the otg cable in to the wall plug or it will not power the external hdd properly and videos will start to stutter because of that as the hdd sucks the energy out of the tablet.

Basically, you will need to change lav video to hardware acceleration (DXVA 2) nad it should do the job. It will ge the pressure off the processor and it will play the video like a charm. BTW Kodi set that up automatically, I didn't even have to tweak any settings in it.

Even without the drivers installed you can recharge your tablet with no issues. You just won't know when it fully recharges. Now you need to reinstall windows and after that reinstall the drivers. You can download them from here:

Thank you my friend. I tried with Kodi (Never heard about this player before) and now my videos are playing perfectly. I'm gonna change hardware acceleration to DXVA 2 later, but so far i'm truly satisfied with Kodi. You were really helpful. :D

In installed windows 10 on my dual-boot chuwi without problems. Everything is working fine.

The only thing is since I didn't have enough space on my C: drive Windows installer gave me a message to choose another place to put the temporary files. I choose the USB drive where I had the Windows install files which had 9.5GB left (on a 16GB drive). I took a lot more time since it had to read/write to the same drive but it worked. The Android partition is still there and the dual boot function still works. The only annoyance though is that after every reboot I get the popup to switch to another OS and I have to press cancel. Except that it works great!

PS: one weird but nice ţhing happened. My C: drive went from 13GB to 18GB total and dual-boot still works so whatever lol, free space!

I'm going with the normal Chuwi Vi8
[Device Reviews and Information] Elram:
Has anyone tested once the battery capacity of the Vi8 Super exactly? I have read the battery report under W8.1 (cmg: powercfg / battery report) with the following result:

Design capacity: 14,800mWh.

Full charge capacity: 14,726mWh

This corresponds to a 4000mAh battery, but not the specified 5000mAh.

In my unit, the battery is discharged under normal use within 2 hours.

I do not know exactly, but I think that in all 8 inch Chuwi devices so far only a 4000mAh battery has been installed.

I think there is also the explanation why only a 4000mAh battery is built into the Hi8 at once.
