Apparantly, kingroot works, however not for everybody. I cant root it with kingroot or irot. It say its rooted,but after reboot,root is still here. Its so called tether-root. I bet that is the reason that i can flash different rom without windows. Flashing starts fime,but i am stuck at Booting to droidboot.img success. Please people help
[Device Reviews and Information] ThatAndroidGuy91:
Kingo root and tether root are not working for me atleast. I managed to root tablet by following this guide:

I swear, I am missing something here..something basic..wont flash..wont root, even on this method..WTF? :crying:
[Device Reviews and Information] ThatAndroidGuy91:
Let me try to help you :) How far can you get with guide I posted link to?
[Device Reviews and Information] varan77:
I start th process cwm runs, but, when it boots it saysE:installer device ignored

E:installer device ignored

Then process continues.. I got to part when i choose with volume keys update supersu.zip. install it,

Wipe the cache. Reboot. No root. I tried drivers, adb 1.0,1.3 intel drivers..zero.

Maybe i missing something inside the tablet except usb debbuging ...who knows..this tablet is great, but is driving me nuts..

I can not root and can not make it only android without wimdows, help!
[Device Reviews and Information] ThatAndroidGuy91:
It sounds like you're doing it right and it should be rooted after installing supersu zip. Did you get any error messages when flashing supersu to tablet? Are totally sure it is not rooted, have you verified it with Root Checker?
[Device Reviews and Information] varan77:
Yes, root checker say its not. Btw, do you have any idea why i cant flash any ROM? It also starta OK, but its Stuck on booting droidboot image? Should I check BIOS ? Or some other option?
[Device Reviews and Information] ThatAndroidGuy91:
It's hard to say as I've not tried to flash any roms to my device. It sounds like your tablet is doing some funky things anyways...
[Device Reviews and Information] varan77:
Maybe,just a tought.. I installed bunch od drivers during countless retries to root,flash..maybe is drivers issue? My tablet is recognized as media storage or android device..shouldnt it be something adb device,Intel or whatever?
[Device Reviews and Information] ThatAndroidGuy91:
It is possible. You might want to try removing previous drivers and installing these: http://www.koushikdutta.com/post/universal-adb-driver. I managed to get it working just by using those.

Must the pc issue....this root method worked for me as well....suprisingly on first attempt, rooted......the android only flash was little bit more tricky....i was stucking at 15%, had to reinstall drivers, pc reboot and it strarted work itself....do not give up, try another pc if u have that choice.

Hi. I installed your CWM and works fine. But I flashed supersu flashable.zip in CWM, but no root. SU bin files upgrade failed :)

I tried kingo root before flash CWM, and I have kingo supersu installed, but it does not work.

Any solution for this? Thanks.

And is here downloadable Android rom for CHuvi Vi8?

Hello:

I have this tablet and a few simple problems:

- I only use Android. I did root it. But normally it shows as not rooted. Sometimes when i reboot, i suddenly regain root. In conclusion, its a matter of lucky....

- In windows, my Microsd is not recognised....is this normal? In android its ok. Its formatted as FAT32.

Apart that....no big problems.
[Device Reviews and Information] varan77:
Its not luck. You have to have full shutdown and than turn on the tablet. SD will be recognized. As for root, try method with super su flash mentioned 2 pages back
[Device Reviews and Information] BlueFlame:
Tried, no luck. :(
[Device Reviews and Information] varan77:
Yes, I know root wont work for me either. And flash too. Soon,when i will reinstall my Windows, i will try again. Its 100% driver thing. I change dozens od adbs, root tools, flash tools..

As for SD card.thing IT MUST work. Check the power options in Windows 8.1 Ii must be on "full shutdown"

I booted ubuntu 14.10 and 15.04 (and made a dd copy of the full emmc), rufus settings are correct. But you have to do some manual work after. I will write a tutorial later, I have no free time now for some hours. Short: you have to manually copy some 32bit uefi files and alter some config and kernel parameters. I found the bits here and there on the net.

Hello folks

I noticed the trend here is more about partitioning, W10 vs W8.1 and stuff.

However, I want to share with you some experiences I had with my CHUWI V8.

The idea was to use the tablet with a streaming app running only on Windows, and seeing that CHUWI has a HDMI connection, I decided to buy it.

The device seems fluid, all the sensors seems to be ok, and the OS switching is working cool.

I bought a microHDMI to HDMI cable and here I got the first issue: the HDMI adapter doesn't came up. Reading all the posts in this thread and browsing a bit the Internet I found the solution: the microHDMI connector (the effective metal connector) was too short so with a cutter I did remove 2 mm of plastic and now the connector is plugging well and the HDMI is coming up normally.

I was able also to project on a TV (not mirroring but only on the TV) reaching FHD (1920x1080) but here the second issue: the image is rotated to 270°. Changing to 0° the display turn normal but when launching any app is rotating again to 270°. If someone has any experience with that, please share it.

How prepare sd card to use in Windows and Android

Hello,

guys, if we can just prepare the SD card to use one partition for Windows accordance with this tutorial: SERACH IN GOOGLE "HACK YOUR SURFACE PRO: UNLEASH YOUR SD CARD SPACE SAVING POWERS!"

A second partition for the Android OS, using the method described here: SEARCH IN GOOGLE "How to swap internal storage with the SD card in Android device"

If so will, I would ask for a description of how and what to do, how to prepare a micro SD card for this to work.

Thanks in advance for your help!

REGARDS!

Hi, i'm hoping someone could help me. So far, i'm satisfied with my chuwi vi8. There's just this minor issue that i wish i could find a solution for it. My battery seems to be not calibrated. When it's discharging it seems to be at random, instead of a pattern. I deleted every partition, and did a clean install of windows 8.1 pro with every driver installed. To check the battery this is what i did, i copied a mkv movie with a size of 1.17gb to the internal memory and with 1280x720, and let it play until the battery discharge. Wifi and bluetooth were both disabled, volume was around 35% and brightness was set to 50%. This video was playing through media player classic that i installed from k-lite mega codec pack. Battery was fully charged:

After 1 hour: 73% of battery left;

After 2 hours: 46% of battery left;

After 3 hours: 18% of battery left;

After 4 hours: 7% of battery left;

And around 4 hours and 17 minutes the battery went to 6% and then the device shut off. It's worth mentioning that the battery was stuck at 7% for almost one hour. It seems that this battery bug also happens to some teclast tablets too. I read at another site that this would fix it. Open the prompt command with administrator rights and paste this command:

powercfg -setdcvalueindex SCHEME_CURRENT SUB_BATTERY BATACTIONCRIT 0

I used it, but nothing happened and i'm still stuck at 7%. Anyone here knows if there's a proper way to calibrate this battery so that it could discharge from 100% to 0% in a fixed pattern? Thanks!

Guys, did you solve this? I have the Hi8 and I can see the 2nd partition fine in Android, the 1st partition (NTFS) fine in Windows, but I can't see the 1st partition in Android (which is the main purpose of the activity!!)
[Device Reviews and Information] BlueFlame:
Using this method I successfully rooted my Vi10 tablet so it's not a driver issue. I suspect it's because we tried to root it with kingo root. This won't allow the Super SU root method once it is installed :(

So I'm afraid the only solution for us is to re flash the android partition... Now to find a correct ROM for the 15050 version...
[Device Reviews and Information] varan77:
So..factory reset is solution? And if kingroot block root..what about stuck at flashing?
[Device Reviews and Information] kkancho:
Are there any custom roms for the vi8?
[Device Reviews and Information] MTK6589:
I had same problem.

But there is a solution, without flashing android partition.

You have to install CWM from here: http://www.tablette-chinoise.net/forum/dual-os-flash-bios-android-windows-8-1-t6953

Download it from https://drive.google.com/folderview...ppX0RRNFVtNzl3b1VLQms4MjBsbnhXQWc&usp=sharing

After that, reboot to recovery and flash supersu.zip from here: https://download.chainfire.eu/696/SuperSU/UPDATE-SuperSU-v2.46.zip

This method does not work with CWM posted in this topic.

Best method for installling Windows 10

Hi,

I would like to share with you how you can easily install Windows 10 on your Chuwi Vi8.

Requirements:

USB ( >= 4GB)

Working Computer

USB OTG Cable (Hub NOT needed)

Able to boot from USB Device

The only requirements are that you have a USB, a working computer for creating the installer, an otg cable so you can use your USB and that you are able to boot from the USB Device. That means you will either have a working Windows install and then you will got to Advanced Startup Options or you will hold the volume down button while booting to enter UEFI.

Advantages to this approach:

No USB Hub is Needed

No Keyboard is Needed

No Mouse is Needed

Drivers are installed with Windows

The touch screen can be used during the installation

Method:

Download the "sources.rar" file which contains a folder called "sources", this folder has files which are injected with the Windows 10 Chuwi Vi8 drivers. The "sources" folder will replace an identical folder on your Installation Media

Create an installation media using the Windows 10 Media Creation Tool

Replace the "sources" folder already on your Installation Media with the "sources" folder I have provided, first you will need to extract "sources.rar" with WinRar or similar.

Boot the installation Media and Install Windows

Thank you very much for reading!

Links:

Unfortunately I cannot share the link as I am still a new user, if an experienced user would kindly message me I can share the link with them and he/she can share it with you.

Sorry for the inconvenience! (Screenshots coming soon!)

---------- Post added at 11:46 PM ---------- Previous post was at 11:41 PM ----------

I am also very interested in this, although windows seems to think mine is discharging normally... it definitely doesn't feel that way when I refer to how long it takes to go from 100 -> 75 and so on. I am going to be updating to Windows 10 soon, will let you know if there is any change.

My Volume Down Button is Not Working Properly

I got this Vi8 about 2 weeks now. The first half day of having it was great. Then the really annoying problem occurred.

The problem is that the volume down button is broken. I can't use it 98% of the time. If I use any of the OSes, the tablet will suddenly slows down the volume. This is really annoying. Sometimes I need to fight with my tablet because when I crank up the volume, after I let go the Volume up button, the tablet will slows it back again.

What's more irritating is that I almost always can't quit the safe mode for Android. I always log in with safe mode thus I can't use third party apps unless I have the shortcuts on my homescreen.

Android will also go to the recovery when I restarts the tablet. And I can't control where I want to select from the recovery because my volume down is non-functional.

I suspect that this is because I pressed down too much on the LCD when I put on the screen protector. I put the screen protector myself and not very good at it because I got bubbles. I try to get rid of the bubbles myself by pushing it hardly on the tablet's surface. But I think that it's not that hard as to bend the tablet.

So what can I do to fix this guys?
[Device Reviews and Information] BlueFlame:
I tried it, and it also doesn't work. Did my best to follow the French texts. Seems a lot like the solution posted earlier and seems like a slightly adjusted .bat file which is translated to French (unfortunately).

Found out that while in recovery mode (CWM non permanent) you can connect via adb and mount the system volume in RW mode. This way you can remove the malware packages and even push your own packages to the tablet. This reduces the need for rooting the tablet (at least, for me :)).

Hy

How do I see the partition with Windows on Chuwi Vi8? Visible me partition with Android OS - 6,78GB. But I do not see partition with Windows - 22.6 GB? I tried to upgrade to 8.1 to win 10 win (it did not work), and that the problem occurred. The partition with Windows has disappeared! I can no longer get into the BIOS using an external keyboard, or start Windows, but only Android? What should I do to solve the problem with the Windows?

When Chuwi turn on (windows option), show me the following message: "Please insert the external storage media and press OK". And there's nothing to react. :(

The touchpad does not respond, Chuwi not be excluded, while the battery is discharged. Or anything over the keyboard to control. Therefore, it only display all the time shows this message. As long as the battery is completely depleted. MicroSD card is in the Chuwi Vi8.

With Android OS is all right.

USB disabled

Hi,

I need some help to reflash my bios, because I have disabled the USB there. :(

This is a Chuwi Vi8 Super, 2215050XXXX with CHUWI2.D86JHBNR01 IFWI .

Currently the the Android works well, and the upgraded Win10 stuck in Windows Automatic Repair loop after an automatic update, so no touch or even OTG mouse/keyboard works to do some BIOS reset or boot from USB devices to fix it.

As I read it can be reflash (reset to default) the UEFI BIOS thru DNX mode. DnX mode works. Can anyone help where/what to do for restore the default values at BIOS, because tried a lot but no success yet.

What I currently searching for a proper flash.xml for Manufacturing Flashing Tool to do just a BIOS FW flash with the CHUWI2.D86JHBNR01 ROM.

Chuwi Vi 8 Dual Boot Windows 10 Drivers

Hi guys. I'm about to upgrade my Windows 8.1 Chuwi Vi8 Dual OS to Windows 10 and I still don't have the latest Win10 drivers for it.

Would someone mind if you can give me your latest working Windows 10 drivers? Currently I'm downloading one from XDA member Levered I think. His is not the Dual OS version.

Will it work?

Before this I've download from TechTablets.com forum member but I can't extract the archive. Hope someone can help ASAP. Thanks.

It seems that I shut down option in the BIOS that prevents booting Windows. Something related to usb in BIOS. I can not enter the BIOS. :(

Is there a possibility to reset the BIOS or upgrade the BIOS, and to do so without connecting external keyboard? Option I shut the BIOS (my stupidity), prevents me to connect external keyboard or a boot USB stick with windows 10?

Can you enter the BIOS via key combinations to Chuwi Vi8, without external keyboard?

Or is the only solution open Chuwi Vi8 and removing the battery, which will reset the BIOS? If I understand correctly? Is someone has such a problem ?

[Device Reviews and Information] CosmicDan:
Not a bad tablet, got mine the other day. Upgraded to Windows 10 using this guide as a reference (mainly for drivers). I noticed that everybody says a USB stick is required, but this is completely unnecessary - you can use the official Media Creation tool on microSD and just install regularly inside Windows 8.1. You will need USB OTG for a mouse however, as mentioned the default touchscreen driver is wrong, so you will need to install the correct one. Just select "Keep nothing" in the upgrade dialog, and remember to run Disk Cleanup after installing Windows 10 (to delete the old Windows 8.1 files) - this is far easier than any other method and perfectly safe.

Next I will be removing Android and expanding Windows partition as detailed by someone here (thanks!); but am also taking full disk image backup just in case I want to put Android back on (but likely not, I have an Xperia running 5.1 for Android and I got the tablet purely for Windows).

Here is my contribution - the Hitachi Microdrive (x86) filter driver attached can be force-installed on the "Generic 0000 SD Card" device (under Disk drives in Device Manager, the usual "Update Driver" button which you should already know about) to have windows treat the microSD slot as a Fixed disk rather than a Removable Disk. This allows apps like OneDrive and probably lots more to use your microSD as if it were permanent storage and will no longer stop you from using it. I modified the INF already for our Chuwi Vi8.

Note that the microSD is still pretty slow compared to internal (even though I have a Class 10/UHS 1 card it is much slower than my phone's Class 10, non-UHS) - for more performance you can change the policy to "Better Performance" (again in Device Manager), and also reformat your microSD with larger allocation units (or cluster size, as it's technically known as). Choosing a larger allocation unit size will make your device less space-efficient, but with the advantage of better read/write filesystem performance. You can read more about it here. I went with 16KB cluster size on my 64GB exFAT microSD - this means that every file will consume space in multiples of 16KB (e.g. a file that is even 500 bytes will actually consume 16KB) and with this cluster size, Steam loads in ~10 seconds now as opposed to over 20 seconds.

Even with that though, the microSD is terribly slow. Random Read benchmarks on internal storage are over 100MB/sec (which is pretty darn good) but the microSD is about ~20MB/sec, which is not so good. Been trying to find a way to improve it, but I guess the microSD hardware is just cheap... if anybody finds any way to improve it, please do share!

EDIT: Ignore microSD issues, the card itself is just slow, even in my phone and PC (which is quality USB3 card reader). Guess I had no idea how slow microSD's really were.

[Device Reviews and Information] CosmicDan:
I used Paragon Partition Manager Pro, worked perfectly. But it's not freeware, I couldn't find a freeware solution. There is a trial but it will obviously stop working after 30 days and I'm not sure if it could be tricked into a second trial if you want to restore. Usually you can wipe and reinstall Windows to reset any trial fingerprints in software, but this trial case might have additional protection from abuse.

Im just upgraded to windows 10 from windows update.

Its working perfectly.. driver all working.. touch screen working.. nothing should be change

except language which is back to chinese.. you can change back to english in setting

After installing you only need to delete old.windows.. its take alot of space
[Device Reviews and Information] CosmicDan:
Another tip for space, although this is just general computing and can apply on any Windows PC - you can create a Recovery Drive (search for it in start menu) and then manually delete the ~5GB Recovery partition via EaseUS or whatever partition program (don't delete the smaller ~450MB one though!) to get even more space. Now my Windows drive is 28.2GB total size, with 19GB free. Not too bad :)

I had a look at the BIOS, so many scary options there - too afraid to fiddle with anything lol. But nothing stands out as a tweak anyway, for battery life or performance, I might fiddle one day after I make another full system backup. One thing I did notice is that you can change the OS dualboot system - I set mine to "Windows only" since I removed Android, but it also has options for "Windows + Linux" and "Windows + SteamOS". Interesting!
[Device Reviews and Information] dicker182:
To make a full backup use macrium reflect. It is free an works perfectly.
