Hello
I bought a Teclast X98 Air II . It says it comes with android installed. Does anyone knows any way to install windows 8.1 on it?
I managed to obtain win8.1 from the teclast forum, the firmware for this specific Air II.
But there was nothing mentioned regarding the bios part. Any ideea?
I will upload 8.1 firmware soon on some share.
Any help? Anyone else with an Air II?
Thanks
Subscribed to this topic as I will also receive my air II very soon and want to install Windows onto it.

done
good news:
1. received my teclast x98 air II
2. managed to install and fully run windows 8.1 bing edition.
will post in the short future a full tutorial that will include rooting, installing, activation
will also provide every software / files needed.
does anyone recommend any file sharing service?
Try firedrive.com - as far as i remember you get 50gb for fairly fast storage.
And most of all - thanks for your help, it would be great if you could write a tutorial here.

Subscribed too, I'm also very interested in how you managed to install windows. I ordered my x98 air 2 a couple of days ago. I will be going to install windows as soon as I get it.
bios brick
can someone send me a right bios for the teclast x98 air 2? i only find x98 air or x98 3g.
i want the bios for android or for windows or both, i take all i can get.
now my tablet cant startup, without a bios. i need a new for external flash.
sorry for my bad english, im from germany, i hope u can understand me
edit:
if i get the bios data i can install any other windows not only the bing version. but with the brick i cant do anything, and i cant find any bios for windows and cant find for android...
i get the hardware driver from another(german) side for display and so on, i just only need the bios data ...
Thanks. I'll be watching this thread as well.
I am seeing conflicting information on whether this tablet has GPS capabilities or not. I would love to have someone confirm what it actually has. If this doesn't have GPS then I'd be curious to know if there are any alternatives.
I am too new to the forum to post links but you can search on YouTube for videos from user HONGKONGEEK where they have posted an Unboxing video for this version of the tablet.
that's awesome, mkdk!!
Instead of the Win8.1 Bing version, is there any chance of flashing a Pro version instead?
I bought this tablet with the high resolution with the intention of installing Win 8.1 so I don't have a pay a premium price for a nicer screen.
Can't wait until instructions are released!
This will be my first post of many .
Awesome work mkdk, did you follow instructions for the first air or the 3g version?
Bought the 3g version for my girlfriend and the android version works well for her. No luck for me with my air II since google play wont work, so now im looking to install windows instead .
Looking forward to the guide!

yes u can u only need the chines bios for windows, than u flash it and u can bootup all windows installations u want: xp, vista, win7, win8, win8.1.
u only need the bios file, than flash, than boot up windows from stick on a 3-usb-hub (u need mouse, keyboard and win-install-stick)
after installing u can take the chines hardware drivers for touchpad, sound and so on and its ready and u dont need anymore the mouse, keyboard or stick. than u can have a winxp tablet with touch, but it isnt usefull, may better win8.1 and all is easy or u can take win8.1 pro, what u want.
only need this .................. bios file... :crying:
bios

AFAIK you can install Pro if you integrate the Teclast drivers into the image (use Wintoolkit & Rufus).

Thanks for the bios nandika6!
So how do you go about his, are the instructions from teclast x98 air 3g also valid for the air 2 when it comes to flashing the bios?
FIY i did the latest OTA from teclast on android and google play/services still does not seem to work so i guess android is a big nono, atleast for now.

best man! you made my day! thanks!
*** I would count these instructions as obsolete due to some gripes with drivers, please refer to JonMichaels instructions in a later post. I will however leave this post if someone needs it as reference or has problems with the other method ***
Ok, so i managed to install both windows 10 32-bit and windows 8.1 pro N 32-bit!
I would not recommend windows 10 since i had a couple of issues there, but win 8.1 works very well with some small gripes that we might solve together!
First a small guide .
Guide to install windows 8.1
For the most part i could use the instructions in the thread for teclast x98 air 3G. I did however not use Teclasts bing version of windows, i created a win 8.1 pro iso instead and embedded the drivers.
Step 1: prepare the image
I only used one usb-drive for my installation (not the WINPE way as described here ), at first i tried with a 32gb drive but it did not work, a 8gb kingston memory did however work. So you might have to test a couple of drives to get it to work. Checkout this post to grab Wintoolkit and Rufus, you will use wintoolkit to inject drivers and refus to prepare a bootable drive.
Once you have these tools you will need to find a windows 8.1 pro 32-bit image to use, i took mine from dreamspark (for students), but you should be able to get one from microsoft directly. Do however mind that i could not bypass the "insert key stage" for a trial version, i had to get a key for this. If you want a fully working win 8.1 pro you will need a key when you install the OS (I don´t know where they are the cheapest, perhaps G2A).
Download the drivers for Teclast x98 air 3G and extract them to a folder. Start up wintoolkit and press all-in-one-integrator to start the embedding process. Browse and select the image that you downloaded earlier. Select the drivers tab and press the Add selection in the menu bar, select the folder with the teclast x98 air 3g drivers, then press start and select a place for the modified image to be storded. Once this is completed (takes some time) close the all-in-one-integrator and select ISO maker, select a place to create a new iso and name it something like "win8.1".
Insert the drive you want to use as a boot-device for your newly created image. Go ahead and start up Rufus and select the drive you want to use. Under partition schema make sure that the GPT partition schema is selected, also make sure that you format it in FAT32. Press the little CD symbol and select the image that you created earlier and press start (this will also take a while depending on the drives writing capabilites). If all goes well you will now have a bootabel usb-drive with win 8.1 pro that the tablet will accept.
Step 2: Flash the bios with the one given to us by nandika6
The next step is to flash the bios to the version that nandika6 gave us. Follow the instructions in this post and use the commands for "if you have not rooted your device".
I had some gotchas with this, simply downloading the adb driver did not work as i could not detect the device in the command prompt. This was solved when i ran the intel manufacturing tools and got the correct usb drivers for the tablet. I did however not do anything with these tools ( look into this if you dont want to keep windows forever, said something about that, i will however not switch back to the buggy Android).
Step 2: Install windows
Once the flash is complete you will have to shut down the tablet and insert the boot-drive. If you end up in the EFI-Shell this will probably be due to the usb-drive not being compatable (this happend to me), in that case repeat step one with another drive. It could also be because the drive is not first in the boot priority, connect a keyboard and pres ESC when booting to get to bios, select the drive and reboot.
If all goes well you will only need to connect a usb-drive since the drivers for touch will work on the fly, if not you will need a mouse and keyboard. The drivers can be manually installed via the device manager (alot of warnings here if this is the case, solve them all by inserting a usb-drive with the drivers folder from earlier).
When this is done you will hopefully have a working istallation of windows on the tablet!
Some gripes
Screen rotation does not work for me at the moment. I solved this in windwos 10 with a file that comes with the drives, this did however make the tablet rotate the wrong way. I will look into this and post a solution if i can, please feel free to inform us if you find a solution first .
The camera is not working for me right now, will look into this.
The tablet will automatically adjust screen brightness even if you turn this of in the power management. This is caused by the intel driver that overrides this, open the intel controll panel and disable active dimming here to solve the issue.
@Thundermeister: helpful guide. Maybe your gripes can be fixed using an updated driver (from the Air II Windows image).
Did you by any chance look into making a WIMBoot image instead of a normal install?

Thanks for the tips mtr33, will take a look at that image (if i can find it ). A WIMboot looks very nice, the space saving would be real nice to have. Right now the install takes up around 8 gb on the tablet. I also found some Onda users having the same problem with the rotation, gonna take a look at that image as well, the tablets seem to use the same sensor for orientation.
For all of you having problems with Google Play store, I have a fix here : http://forum.xda-developers.com/showthread.php?p=56779242
This works on both 4.4.2 and 4.4.4 ROMs.
Easy instructions & 100% working Win 8.1 install coming soon...

How to install Windows 8.1 on a Teclast X98 Air II Android Tablet:
You will need:
2 USB Memory sticks - 1 small (no more than 8 GB) & 1 large (6 GB or more)
1 USB Hub (preferably USB2 & powered)
1. Go to this web address 1drv.ms/1EQ1X5v (Microsoft Onedrive) & Download all the files to your computer.
2. Plug the small memory stick into your computer & format it (Right Click on the drive's icon then scroll down & Click on Format) using FAT32 File System & set the Volume Label to WINPE (all caps).
3. Decompress WinPE_User_20140814.rar to your computer & copy the files to the root directory of the memory stick. Eject & remove the stick.
4. Plug the larger USB memory stick into your computer & format it using NTFS File System.
5. Decompress X98_Air_II_Windows_20141022.part1.rar to your computer & copy to the root of the 2nd memory stick. Eject & remove it from your computer.
5. On your Android tablet, go to Settings, Developer Options, & check USB Debugging (then Ok).
6. Decompress X98-Air II-WIN8 bios.rar to your computer.
7. Connect one end of the USB data cable to your computer & the other end to your tablet (close all running programs on your computer & make sure the tablet has at least a 50% charge).
8. Open the X98-Air II-WIN8 bios folder & Right Click on X98-Air II-WIN8 bios.bat & Click on Run As Administrator (enter password if prompted).
9. Type 1 & press enter to install the USB driver (Install driver dialog box should pop up, click Next to finish the installation).
10. Type 2 & press enter to Root the tablet (wait for it to finish).
11. Type 4 & press enter to flash the tablet's BIOS (do NOT disturb tablet or do anything on your computer while it is flashing!)
12. If there are no error messages, press the tablet's power key for 10 seconds to turn it off & pull out the data cable.
13. Plug both USB memory sticks into the USB Hub (& plug it in to the wall, if powered) then plug the Hub into the USB adapter (that came with the tablet). Plug the other end of the adapter into the tablet's micro-USB port.
14. Turn on your tablet & leave it alone until it is done installing windows (should take several minutes).
15. Hold the power button for 10 seconds to turn it off, then turn it back on.
16. After Windows 8.1 loads, change it to your desired language (it will be in Chinese) & enjoy!
hey! i just got teclast x98 air 3g from my university and apparently its was only on android only and it bios was locked. so i flashed the latest bios to unlock dual boot option and i succeeded. Now it has dual boot option but only shows android. can any body please guide me thoroughly on how to install windows 10 in it also with android still being available as dual option. its c8j7 model of x98 3g air.
please help i really want to use windows 10 on this with android. Any help will be highly appreciated.
Thanxx
You should just have to download Windows 10 (32 bit edition) from Microsoft and install it on a USB Drive (GPT + Fat32).
Just be sure you have empty space on the "hard drive" and start the X98 and press ESCape key to go to the boot menu and choose your USB Drive.
If Windows have enough space it will install itself and create the 2 partition it need, that's it !

Hi,
I wanted to install Windows (any windows version, really) on my X98 AIR III (MC5C5). The current OS is Android.
My first attempt resulted in a hard brick, right after trying to flash the bios using a tutorial on cngadget.
Got my tablet repaired, allegedly it has dual boot BIOS now AND win10 has been installed on it, but it was removed due to licensing.
Still, the tablet BIOS does not recognize any USB stick or microSD I put into it, so I can't run any Windows install.
I've used both official teclast files and regular ISO's on FAT32 format.
Did I go wrong somewhere with the install files, or is it something with the BIOS?
Hello,
since it took me some time/reading/doubts before succeeding I post here a very simple guide for those of you who would like to have the max from the x98 teclast in Windows (I have a A6C9, but the same is applicable to other models).
Basically installing everything without a Hub/usb or a keyboard.
First download the latest official version here: http://www.teclast.com/tools/pad/pad.php?t=p
you simply add your model number, in my case A6C9
you will then arrive to a horrible baidu website (http://pan.baidu.com/s/1qXTtxgS ) where in theory for downloading you need to register, and it is not always working. So here the solution is to download http://jdownloader.org/ and install it in your PC
then run jdownloader and copy the http address of baidu folder (http://pan.baidu.com/s/1qXTtxgS ). Look at the address, sometime it is too long and it will not work, it should be quite short, like mine. You can now press start in jdownloader to start the download of all files of baidu website without the need of registering!
then Format FAT32 a 32Gb USB stick and put the name of your usb stick “WINPE” (important!)
unzip (http://7-zip.org/) the downloaded Windows 10 teclast edition and copy it to your usb key and connect it your your X98 with the simple cable provided by Teclast
look for the file name “wimpart.txt” and replace it with this one https://mega.nz/#!mAhXzSIK!iGAV-a8hy2N8G1s9Gy1Z96bILS147slzPCGkF269aKg (if you do not want have only W10, and you want to keep Android, then you simple ignore this step 4).
make sure that you have at least 60% of battery (better full) and then in Windows10 go to Settings–>Update and Security–>Recovery–>restart now. Then you select Troubleshooting–>start UEFI
You are now into the BIOS and you in “OS IMGE ID” you select “Windows”. Then from the bios menu “Save & Exit” you select your USB key from the section “Boot Override”.
And its done!!
Now are you installing the latest official W10 from Teclast without any keyboard (with no problems of drivers etc.), full use of the 60GB and you are happy
Cheers
Hi. Thanks for the tutorial. I have a problem with it tho. My model c9j7 doesn't appear to have windows 10 drivers on the Chinese webpage on teclast website. It only shows windows 8.1. Do you think I still can do it? In case I don't can I just follow the same steps and stay with windows 8.1 instead?
thanks
