[Teclast X98 Air 3G] Mark the Red:
Thanks for all the help so far. Got everything working with the Windows 8.1 Pro ISO, with the exception of one thing.

My tablet does not auto-screen rotate. I tried installing the Kionix Accellerometer SPM driver from the Teclast 2.21.201 5.zip pacakge posted on this thread, but it keeps giving me an error message.

Device manager does not recognize the device, and when I point it to the correct driver file it gives me an error.

Can any of you guys running Windows Pro 8.1 on this tablet tell me what is the trick here? Its the only thing I have left to get running.....I'll bet its something REALLY simple...

The AIR 3G sensor Gsensor file worked......sorry for the mistake
[Teclast X98 Air 3G] Venomke:
After trying different things over the weekend i've managed to reïnstall windows (had to use a pro .ISO since the W8.1 with bing wouldn't work). I've installed all drivers from the 3G-thread. Only issue I still have is that the screen is at 48Hz instead of 60HZ. I'm going through the 3G-thread for a fix but not being able to find one yet.

Does anyone have a quick-fix for this problem?
[Teclast X98 Air 3G] streetsmart999:
Follow the steps for here http://windows.microsoft.com/en-us/windows-8/create-reset-refresh-media and then in bios select USB as bootable. NOT SURE IF YOU LOOSE UR WINDOWS KEY. Cos some say its embedded into Bios and some say otherwise.
[Teclast X98 Air 3G] Venomke:
Hi I've downloaded an .ISO of W8.1 with bing "somewhere" but this didn't work. It wouldn't install so now I have a pro-version installed (too bad, i'd like to use my keep using my Bing-license to update to W10 once it comes out). Only issue I'm having so far is that the screen refresh rate is now 48Hz instead of 60 Hz I used to have. :confused:
[Teclast X98 Air 3G] streetsmart999:
I think that issue is Bios based. ( "THINK" is the Keyword), Did you change your Bios?
[Teclast X98 Air 3G] swidmier:
Need help badly, Teclast Air ii (HG8N)

I brought this on myself. I read how to get more space by making a recovery USB and deleting the recovery partition on windows tablet....free space! I needed it to sync all my work google drive docs. So, I deleted the 4.86gb partition that said "recovery" in the title and added that space to my windows partition. Now, when I boot windows it boots to recovery saying required device isn't connected (error code: 0xc0000225) and I should use recovery tools on installation media. Press windows key for UEFI Firmware Settings. When I try booting in Android, it acts like it is going to boot then restarts back to the select system window.

So, I decided to follow instructions provided and flash the tablet. I got the tablet to be recognized and made it through to 10% until Error : Port 0/0/3 #1: Device on port 0/0/3 #1 timeout to enum adb (TIMEOUT = 180). Tried it several times all with the same result (definition of insanity).

So, how do I recover?

Hi, i'm having problems with hg9n.

At first i installed a custom ROM, but i got touch screen issues, like it was uncalibrated.

Now i tried with Windows and the DualBoot BIOS and Win has the touch screen vertically inverted.

I don't know what to do T_T

Edit: Chinese guys has the same problems

[Teclast X98 Air 3G] 25gee:
Hi lokkiyo, I have a HG6N which may be different, but try this, Install the drivers for the display driver and the accelerometer from the driver pack (if you don't have this look up the dual boot thread for the "Air II 3G") once you have installed the drivers for them, plug in an external mouse/keyboard just to be safe as the touch display may stop, right click the accelerometer device in device manager, disable it and re-enable it, this was an issue on both of the HG6N Air II that we have here and doing so corrected the orientation so that flipping it to portrait was the correct way up instead of inverted.

---------- Post added at 03:39 PM ---------- Previous post was at 03:34 PM ----------

Swidmier, you should still be able to flash correctly using those tools, I trust that you are loading the flash.xml prior to plugging in the device so that it starts? please check to see if the folder names of anything on your system contains any Unicode/Chinese characters and rename them accordingly as these folder/file names can sometimes cause the flashing process to timeout/fail and has caught many of us out before.

The recovery partition is part of Android and should under no circumstances (if you wish to remain using android) be removed, this along with system/user/data and a few others are essential to the operation of the Android system, why it has affected your windows partition from booting I do not know, I can only assume that by deleting said partition you have perhaps messed up the partition table and caused an issue there.

Try re-flashing the device using the tool that hangs at 10% and ensure that NO folders/file names have any Chinese/Unicode characters in their name at all, see if this allows you to get past 10% as the device is being seen that is a good sign!

---------- Post added at 03:42 PM ---------- Previous post was at 03:39 PM ----------

Venomke: Windows 8.1 with Bing did have a refresh rate issue, this was related to registry/driver issues and was resolved in the ISO's provided for Windows 8.1 Pro on the dual boot bios page, if these are asking for a license key then that is very strange indeed as the key is embedded within the BIOS as stated previously by streetsmart.

If you have the dual boot BIOS this should be working fine and installing correctly, minus a few driver issues which are resolved with the drivers zip provided on the thread for dual boot, windows 10 is going to be license free apparently so you should be able to download and install that regardless in the future.

---------- Post added at 03:56 PM ---------- Previous post was at 03:42 PM ----------

Apparently someone was working with the devs to get a display driver and support for the touch panel working in the linux kernel, but I heard nothing more of this, as for the order to install, always do the bios then install android first and windows last with the remaining space.

The partition sizes can be modified in the partition table xml file for the flash utility for Android, the free space will be taken by windows so this need not be a concern as you are only modifying the partitions for one OS.

air2 HG8N -> android partition flash

Thanks to you for all your time & effort with this stuff

My idea is to keep the windows partition and everything else as it is, and just flashing the android partition with your ROM to get rid of the chinese app etc...with all the mods you've already added (spanish menus, spanish file browser etc...) .. will I have later any problem to boot into windows? I dont hope so..

So I'll start this weekend, I still got a lot to read.

Thanks again for your help & keep on the good work!

Fixing OS

25gee, I am starting the flash program before I load the device. Not sure how I can check for unicode or Chinese on the folders on the device as I cannot get an operating system to start and can't seem to access the drive from a regular computer. I have used two laptops, one couldn't see the tablet but the other one could but it hung at 10%. Looked like the computer could see the tablet but the tablet couldn't see the computer to start the flash. Nothing but waiting for fastboot command appears on the screen.

---------- Post added at 05:33 PM ---------- Previous post was at 04:34 PM ----------

Just tried it again and got the same error. OS flash failure ADB ENUM failed.
[Teclast X98 Air 3G] swidmier:
Still no success......

I am still unable to get flash to work in order to save my Teclast x98 air ii. About ready to throw the think in the trash despite this being my fault. I found the thread on issues during the install stages and the, following the advice, reloaded the three USB files. While loading the

isoc USB driver I tried power cycling the tablet. Of course, the furthest I can get is the select operating screen. I cannot boot into android meaning the tablet isn't seen. I have also tried DnX mode while installing the Isoc USB driver. This didn't seem to work either. The flash process still gets stuck at 10%. I am unable to access the Teclast x98 air ii drive to rename any files. The last message I get from the flash tool is: 04/10/15 16:30:16.436 ERROR : Port 0/1/1 #0: Device on port 0/1/1 #0 timeout to enum adb (TIMEOUT = 180) . Please save a Teclast x98 air ii from destruction!

---------- Post added at 04:35 PM ---------- Previous post was at 04:31 PM ----------

I am hoping that quoting might help you see my continued issues. I cannot access the Teclast x98 drive to see the file names. I have tried re-installing the USB and flash tools several times with varying ways of power cycling the tablet during the ISOC install. Still hangs at 10% saying: 04/10/15 16:30:16.436 ERROR : Port 0/1/1 #0: Device on port 0/1/1 #0 timeout to enum adb (TIMEOUT = 180) . About ready to drop this tablet into the depths.
[Teclast X98 Air 3G] MrRimmer:
I'm sorry I can't assist with your issue but just to say that I have plenty of experience flashing MTK chipset devices and I have found this device much more difficult to get working. It took me quite a few hours to get my H6GN flashed to Windows. My only suggestion is to find a PC with a clean Windows x86 installation and try again from scratch with the Intel flash utilities.
[Teclast X98 Air 3G] RicePuffs:
I'm also having the same issue. I have hg9n which i installed windows on using jonmicheals instructions but the touchscreen seems to be inverted and i can't fix it no matter what i've tried.

I haven't tried the msc.edit method because I don't have win 8.1 pro.

Next step i guess is to install win 8.1 pro on it and try the msc.edit fix.

Anyone have any other suggestions?

Windows License

Hi there,

I just reinstalled Windows 8.1 with Bing on my tablet, but Windows started annoying me with notifications about the fact that the license key is not valid. I tried to look for solutions, but to no avail. I called Microsoft Italy and they basically told me I'm screwed because I have to ask Teclast and they will provide no support because the tablet is a Chinese product. Does any of you know any way to make things correctly work? Thanks!

So, I've just recieved a new X98 Air II after heating issues with my last one.

Now, my CPU seems to be stuck at 1,33 GHz.

In the tablet I have just the info "Entering Dnx mode. Waiting for fastboot command".

Nothing else.

Battery drain problem with W8

Hi folks,

This is my 1st post so I would like to apologize for my english... I'm french!

I just received my new teclast HG7N with dualboot and a have big battery drain problem (about 4% per hour in Cs).

I have tried to change the "Intel SD Host Controller" for the "SDA Standard Compliant SD Host Controller" as mentionned in the 3G thread, but I have still the same issue.

So I would like to install the "windows only bios" to - I hope so - solve this issue.

I would very much appreciate if someone can post a link to the last "windows only" bios that I can use with my HG7N and a the last W8 with bing iso from teclast., or to bios + drivers that solve the battery drain issue. PLEASE!

Cheers!
[Teclast X98 Air 3G] streetsmart999:
Installing Bios and All that might Screw up your tablet.. and You might have to go through lot of pain if you don't do it right. Mine is exact same tablet (HG7N) and I could not figure it out yet.

1. But Battery drain reduced When Keeping the Tablet in Airplane Mode (If you don't use Bluetooth) and keeping Wifi On. (For Syncing)

2. Make Volume Mute before the sleep button.

these 2 steps will help reduce battery drain to 2-3% (Depends on your luck)

Also there is no Know solution for this as far as I know.. I have been searching the inter-worlds for a fix but with no luck.

Good Luck. and Let me know if you find anything.. or if this helped u.

---------- Post added at 11:30 AM ---------- Previous post was at 11:24 AM ----------

unfortunately thats the only solution we have other than flashing the entire image from Teclast again using (USB HUB). I got burned by this same problem... I reset my tablet and Lost the key. I did this before on other Win 8.1 tablet and never had any issues like this.. (I guess buying Chinese stuff has its own risks). Anyway I did not go through this like (provided above) but something similar from Teclast forum. :( So if you find a different solution please let me/us know.

First tanks for your answer.

Actually I try to use the hibernation mode as often as I can but it's not a solution.

Do you already tried to Install a only Windows bios? Cause i don't care about the android partition.

The question is : wich only Windows bios version is compatible with HG7N?

Lost Activation after RESET Windows 8.1 with Bing Fixed.

Back story: I wanted reset my Dual Boot x98 Air 2 (HG7N) and I selected clean all and re-install Windows option in reset . When the System came back it did not active my system for some reason. I though I lost the key when I was performing the above mentioned Reset. I knew the key is embedded in Bios but for some reason It just dos'nt Activate , I noticed some how it became Windows PRO after following some of the guides here in XDA and In Chinese forums. Finally I activated it using some tools provided on Chinese forum but never comfortable. At that point I had Win 8.1 Pro activated but I was not satisfied and I wanted the way it came from factory. Windows 8.1 with Bing (Genuine Key)

Fix: Today I tried to Reset again but instead of selecting Format and Re-Install Windows I chose the Option 1 which is Just Remove my Files option in Reset. When the Tablet Booted back it was completely Chinese (and All the accounts and everything were gone and was looking like factory reset) So watched the menu's on different computers and Made it to English. and Once I connected to Internet .... Magically it got activated and when I checked the OS version its now Windows 8.1 with Bing and Activated Like it came from factory.

Edit: This worked for me.. But may or May NOT work for you.. Good Luck.

Attached are the Pictures.

Teclast X98 Air II (HG8N) Dual Windows BSOD

Hi

I just bought the Teclast X98 Air II (HG8N) Dual Boot. The android runs fine with video playback (netflix, youtube etc). The windows side however, does not playback video at all. As soon as I play the video I get a BSOD Video Scheduler Internal Error or the entire thing might just freeze (that happens when browsing too). I updated windows and update all the drivers with Drivers Booster 2. I email teclast with no response.

I am new to posting things at XDA so if this is in the wrong spot. Please guide me towards where I need to post this to get help. I really like this tablet and the idea of dual boot. But with windows acting up so much, it makes it just an android tablet.

Thanks to anyone and everyone for helping.

Thanks Ken for your reply

If I play a video through my a file of my own on windows, it runs fine. So does XBOX music apps videos. Its weird that any video on any browser through any website will freeze the tablet or give BSOD. Any apps other than the ones I mentioned will do the same, freeze sometimes other times BSOD.

I just removed the android partition and installed windows on the whole thing. Still having the same issue. I played through VLC its fine if its a video stored on the tablet.

I am scratching my head on this one because it cant be a hardware issue if android is able to play the videos fine and so does windoes in few apps. There has to be a software problem and I already updated the drivers. Please help anyone? I am really stuck on this and I like the tablet.

I flashed the Cube i6 rom (that is, the system.img file only) on the x98 after reading it was a way nicer rom (hardly any bloat) and because I'm not too excited about the x98 android rom. I was hella surprised that almost everything actually works, but there are some issues:

1. NTFS is not recognized/mounted...

2. The touchscreen/digitizer is flipped! Meaning the display is upside down, but the digitizer registers your presses normally. So the home button is at the center top now, but you have to press center bottom! I tried a screen rotate tool but that rotates both digitizer and display.

Other then that almost everything seems to work!

Sound, wifi, brightness, bluetooth.

But anyone with ideas on how to fix the touchscreen issue? Where would I have to look?

Found a ro.sf.hworientation=180 or something setting mentioned as well, didn't work. Some ways of editing a so called script.bin file, can't find it on this one... Any ideas are welcome!

I like the windows 8.1 but the battery life is too terrible.

The android install has better battery but the slow scrolling and laggyness makes it feel more like a 1.2ghz single core!!! It must be really badly optimised.

Does the Mirek rom make android much better? faster?
