[Teclast X98 Air 3G] towe96:
I've just ordered an Air II after seeing a review and deeming it the best Windows / Android combo for the money.

Then one I'm going to get is the stock-Android version, without Windows being preinstalled.

Now, I've seen that there's a couple of different guides as to how to install Windows 8.1 on the Air II.

Which one of those is the most current / successful version?

I doubt I'll need dual boot after getting Windows, so I'd be fine if it just ran Windows nicely.

Getting the required licences is not a problem for me as I've got access to DreamSpark.

Let's hope for the best,

towe
[Teclast X98 Air 3G] YYCLeo:
Thanks for the instructions!

I'm stuck on trying to transfer install.wim which is over 4gig on a FAT32 format.

any way around this?

EDIT: New instructions provided. See post #20
[Teclast X98 Air 3G] JonMichaels:
Oops, NTFS is necessary for files over 4GB!

I edited the instructions...

Sorry, my original installation used a compact version of Windows that was less than 4GB. You need NTFS formatting because the full install Windows image is over 4GB. Please refer back to the instructions & let me know if you have any further questions.
[Teclast X98 Air 3G] Thundermeister:
Im downloading your image to try and extract the drivers for the kionix sensors :), but it´s failing, will keep trying!

Would it be possible for you to run driver backup (from source forge) on your tablet and post these drivers if you have the time John :)? There should be one driver for sensors I/O and two drivers under just sensors.
[Teclast X98 Air 3G] JonMichaels:
Latest Teclast X98 Air II drivers for Windows 8

I uploaded all the latest drivers to here --> 1drv.ms/1EQ1X5v

The file is called, driver_backup.rar

Enjoy :)
[Teclast X98 Air 3G] Thundermeister:
Wow, thank you Jon!
[Teclast X98 Air 3G] Patent_Litigator:
What method did you use to root the Air II?

Edit: This one works. Google Play store and apps are working now on my Air II.

X98 Air 3G toolbox, see the second message on Air 3G thread.
[Teclast X98 Air 3G] JonMichaels:
Start with Bing, you can always go pro!

I would start with Bing version. It's optimized for this device & includes the drivers already installed. You can always upgrade to Pro afterwards by just entering a pro Key. As for the modded ones, I haven't tried them so I can't really comment other than to say Bing/Pro seem to run pretty fast already. Hope this helps!
[Teclast X98 Air 3G] Thundermeister:
My windows pro install takes around 12gb with all the updates, would probably be less using the wimboot as suggested earlier in the thread. How much space does the teclast image take?

My sensors still wont work even with the drivers provided by Jon, so i would probably recommend using the teclast version. How about license with the teclast version? Do you still need a key after 30 days for this version?

I also ran into som problems when i tried steam in-home streaming, it lags even when streaming 720p (lags alot), this should work with the hardware. Could someone try some in-home streaming with the teclast image (If you do game that is :))?

Other than that i love win 8.1 on the tablet, its silk smooth and i IE11 is actually very nice to use in the metro-mode.
[Teclast X98 Air 3G] JonMichaels:
The image I provided is the Teclast version!

That's strange that your sensors aren't working because mine are working fine. I would try reinstalling Windows with the image I provided. It's the Bing version straight from Teclast that has all the drivers already installed. Let me know if that fixes your issues...
[Teclast X98 Air 3G] Thundermeister:
I will probably do that! How much does your install take up on the ssd?
[Teclast X98 Air 3G] JonMichaels:
Not sure cause I have a bunch of stuff installed now... I would say maybe about 19GB was available after the install?
[Teclast X98 Air 3G] bluessonny:
activation???

Firstly many thanks [MENTION=6163269]JonMichaels[/MENTION]! This was straight forward enough for eve a total newb like myself to successfully follow. I could not be more grateful, 1000 thank yous.

I have a quick question around activation. From everything I read online around M$ providing free licensing to these cheaper tablet makers I was expecting (hoping) this copy would be activated, but I am getting a message stating the key is blocked. Is this normal? (I am just using the standard bing version and in-built key provided). Do you have any guidance on what is the process with activating these tablets via the M$ tablet arrangements? Many thanks once again.
[Teclast X98 Air 3G] JonMichaels:
I was hoping that was the case too but unfortunately I couldn't get any of the versions I tried to activate. I had to buy a key. Luckily, I found a Win 8.1 Pro key on eBay for cheap! I will let you know if I figure out a way to activate the Teclast version though...
[Teclast X98 Air 3G] bluessonny:
Thanks again. The w8 pre-installed versions on tinydeal.com etc have been out a couple of weeks now. would be interesting to hear how any of those users have got on regarding activation? I am assuming those must be pre-activated? Meantime I am loving this device with W8 installed, it works much better than I had expected at the price. Many thanks again for your help.http://cdn4.xda-developers.com/images/icons/icon14.gif
[Teclast X98 Air 3G] mtr33:
I don't have mine yet, but AFAIK the pre-installed Win8 versions come preactivated. Most likely there is an OEM key embedded in the bios that corresponds with the image. Did you guys instal the normal way or did you make a WIMBoot installation? Not that it would matter regarding activation, but it seems to me the way to go taking into account the limited storage. Just my 2ct.
[Teclast X98 Air 3G] scrawl78:
Hi all,

I picked up my Teclast x98 Air 2 Win 8.1 edition. Here are a few observations:

Camera is not upside down (not sure if this issue was specific to the 3g model)

Screen refresh rate appears to be 60khz (not sure if the 48khz bug was specific to the 3g model)

C drive is 24 GB in size. Windows takes up ~8GB

On first boot, Windows prompts to activate. This involves enabling wifi, clicking 'activate' and waiting for MS servers to respond. It activated without issue.

Haven't had much of a chance to to anything with it yet. If you have any questions, happy to test anything out for you.

For anyone considering purchasing this tablet you might want to wait for a few weeks. Seems like they're already testing a dual boot edition (It's mentioned on their forum and Weibo account). My hunch is it would be another HW revision and released as a new model.
[Teclast X98 Air 3G] JonMichaels:
Can you copy & post the installed drivers so I can make sure the ones I uploaded are the latest drivers? Thanks a lot!
[Teclast X98 Air 3G] Thundermeister:
A driver rip would be much appreciated :).

my dual boot android (stock ROM modified and improved by jcespi2005) OS just received an update alert from Teclast. I am hesitating to update it as it might demolish Windows partition. I don't have any issue with Google Play Store and my Android is rooted.

Any ideas?
[Teclast X98 Air 3G] kinhvanhoa:
I am using the dual bios on the front page of the Air 3g iinstruction. It works OK though. I have no idea about the official update on Teclast since I don't speak Chinese. Is it really different?
[Teclast X98 Air 3G] chaplinu:
I made from many places but basic is here

First I made it`s ROOT ( my Play marked not worked). I installed 3 tools drivers as described and after flashed with adb.

After that I made BIOS same way ( adb) because many users warning about UPDATE apk.

Only one BIOS exist for all AIR tablets: X98Air3GDuala.bin

Next step is flashing with "Intel Manufacturing Tools" Android ROM. I used lite version from Russian forum but many of it exist.

I flashed with Entering DnX mode as in instruction. As I said "Droidboot" not work in my tablet by pressing buttons but it not need in my way.

Last step is Windows installation. I made USB stick with Rufus and got Windows from Mega.

I connected USB hub with mouse and keyboard and USB stick with Windows installation. When you will see Windows logo I moved mouse on it and pressed "Enter" on keyboard and Install begun.

When you will see a lot of partitions for install ( ~ 10 !) last one was 24 G I selected it and formatted and installed on it. In end I made update for all drivers as usual.
[Teclast X98 Air 3G] xxLeoxx93:
1. Did yo use the bios file from the tutorial you linked to?

2.Which Version of the x98 Air II do you have?

3.Do you use it as dual-boot or only with one OS?

Thanks!
[Teclast X98 Air 3G] chaplinu:
1- As I told ( As I know) exist only one file of BIOS. But exist many ways to make it. I used ADB interface

2- I received X98 Air II (HG6M) with Android

3 - And made dual boot as described before. Android + Windows 8.1

Each time I power on I see 2 options for select OS. If I not click it use last I used.
[Teclast X98 Air 3G] xxLeoxx93:
Thanks!

I asked, because there is a Bios file for Windows: http://xdaforums.com/showpost.php?p=56743185&postcount=11 ;)

Do you have any problems (like missing drivers) with the bios you used?

Thanks again for your help :laugh:

Windows seems to work now. Though only at 48p, which is unacceptable.

How can I get it to run at 60 Hz?
[Teclast X98 Air 3G] towe96:
Update: Using the DualBoot Bios but only installing Windows (see the comprehensive guide for the 3G, it can be adapted 1:1 with minor changes) results in perfect 60 Hz screen refresh.

Ask me for details if needed.

Just got this tablet from aliexpress with dual boot installed. Noticing crazy battery drain in win8.1 while idle (roughly 93% battery drain over 10 hr period). Nothing of the sort in Android, only 3-4% overnight. Is this a BIOS issue?
[Teclast X98 Air 3G] towe96:
It's exactly 93%, isn't it?

It's a known issue that Windows doesn't display the correct charge remaining and gets stuck at 7%.

Follow this guide: Battery Fix on XDA

anyone installed on the Mirek190 custom Rom on the Air 2 recommended in the comments section of the video?

I'd like to go back to Android but only if it's stable but Win 8.1 does everything I need without any issues.

Any feedback on the custom rom guys?
[Teclast X98 Air 3G] zerogees:
Thanks for the response - checked this morning and it was 11%. Was on 85% when I went to bed 8 hrs ago, so I don't think its a windows display issue.
[Teclast X98 Air 3G] Jazah:
I also appear to have battery issues for windows (running dual bios). Overnight it will go down 30%+ while on standby.

The battery meter appears to be working correctly, its just genuine drain. I've tried all the fixes I can find related to windows "connected standby" poor battery issues, but nothing has worked. When it's booted into android the battery only goes down a few % over several days.

At first I had it running windows on the non-dual boot bios, and I don't remember any battery problems.. but I didn't really pay attention.

As for custom Android ROMs, I've tried 3-4 that have been linked throughout the forums (not Mirek190 specifically). But each one of them I ran into certain issues, updates not working, google sign in for certain apps make them crash, etc. So I ended up using the original ROM, rooted it and removed all the bloat, and its been running great since.

I believe I just used the x98 Air 3G BIOS Here listed on this page:

http://xdaforums.com/android/general/teclast-x98-air-3g-tablet-9-7-2048x1536-t2913035

And it worked fine on my Air II.

Only problem was the 48hz refresh rate. Which the only fix I know of is to instead use the Dual Boot BIOS but just install windows (if that's all you want).

The procedure for this is also listed in that same post:

Hey there sunshine, I just did that yesterday in order to have the advanced BIOS options.

It's perfectly easy. All of this can be done directly on the tablet.

I used the Windows-BIOS from JonMichaels (1drv.ms/1EQ1X5v -> BIOS).

In there, you'll find a file called "X98_Air_II.bin".

Now, you download the "BIOS_X98_Air_3G_win_to_android" file found in the thread for the Air 3G under the "Windows -> Android" section.

In there, you'll find a file called "X98Air3G.bin". Just delete that and put the "X98_Air_II.bin" in there. Change the name of that file to "X98Air3G.bin" and run the "flash.bat" file.

Now, if the command prompt delivers an "FTP operation passed" notification, you have the original BIOS installed.

Make sure to run the .bat file with Administrator privileges.

Updates from Teclast and MX Player codec problem.

Hmm... Today, I tried to update my android (on dual bios) with Teclast's offical release.

It failed to install the "updates 01" with Teclast Autoupdate.

It seems to happen because my android is rooted though.

Is that because I use the dual bios and rom modified (but based on the stock rom)?

Another problem I experience is with MX Player Pro.

It's installed but when I try to install the CODEC (X86) from Google Market it says it cannot be installed because "Incompatible with other applications using the same shared user ID." Weird.

I tried to download the codec from other sites. It doesn't play sound. Probably it's a MX Player Pro program.

Any stable version of this player on AIR II?

Any ideas? Thanks.

Newbies shoudn't touch these things.

Hello everyone,

New to the forum with a newbie question.

I have a rooted HG6M. I attempted to use Viper4android to modify the built in speaker gain with no success. As it turns out, I was applying the effects to my headphone output. Before I discovered this I uninstalled Viper and the effects remain. Lots of reverb, echo, and a severely distorted equalizer. I tried reinstalling Viper, but it treats the previous changes as default and does not recognize them :(

Is there a manual way to edit audio file settings via root file explorer to restore to default values?

Please help! and Thank you!

Hi all!!! I have a Teclast x98 Air II Dual Boot (HG7N) and I would like to change the android ROM (I'm having some issues with my wifi on android). Is there any way to just install a new ROM over the old one without "touching" Windows partitions?

Thanx all!!
[Teclast X98 Air 3G] microb77:
Yes, both Mirek and JCEspi2005 have a "System Only" Xml file you can use. I did it with Mirek's and it worked just fine.

The way I did it is:

1. Prepare Intel Manufacturer Utility using the normal process

2. Select the "System Only" Xml

3. Boot your tablet holding power + vol - vol (yes, the 3 buttons together, took me a couple of shots to realize that haha)

4. plug it in your PC USB

Intel Manufacturer will update only the Android System partition.

Best of luck!

Adroid flash problems

Hey there!

So i just got my Air II (HG7N) and wanted to do a clean install of both OS (Windows+Android), so i installed win 8.1 pro (formatted everything until one partition and installed windows) everything went fine so far.

now im trying to install android so i followed the guide done by Hendrickson and installed the mirek rom..as far as i read, this rom (usually 3g models) should also work on the Air II. I followed the Instructions step by step, connected the Tablet with my PC and started flashing..and at 33 % it stops with the error message:

01/23/15 17:33:24.626 WARNING: Port 0/1/1 #0: Failed to execute "fastboot -s Baytrail0000088C -S 100M erase cache":

erasing 'cache'...

FAILED (remote: unable to format)

is this cause i use all my space for windows and i have to do a manual parition just for android to flash it or what could be the problem?

thx for ur assistance !
[Teclast X98 Air 3G] 25gee:
I'd imagine it is because you have deleted the "Cache" partition, android consists of multiple partitions and is generally installed first on a multi-boot setup using the partition table file from within the Intel flashing utility.

You'd then continue with installing windows to the remaining free space, hiding the android partitions in the windows admin tools once installed.
[Teclast X98 Air 3G] Xayfer:
i did this first just installing windows over the old windows version with stock android rom as second boot. But during the installation process the windows setup failed and i got a message" no efi partition" and it rejected. after deleting all the partitions it worked. so do i have to do a clean install of android first and then install windows on the remaining disk space?
