Hi,
Any ideas how to update drivers in windows 10 for the Hg8M tablets. I mean, I am familiar with the process of updating drivers per say, just not sure how many things to update or where to start.

Hi I ordered a Teclast x98 Air ii 64gb version with Windows 10 and Android installed and it arrived today.

But I am a newb at this and a bit confused about the hard drive capacity.

When I got to "This PC" in Windows it show under "Devices and drives" 19.0gb free of 32.8gb.

If I go to settings/system/storage it shows 19.0 GB used out of 38.0 GB.

When I boot up in Android and go to settings/storage it shows Total Space 16.53 GB.

None of these capacities come close to the 64 GB that it suppose to have. Have they sent me a 32 GB version instead of the 64GB version ? or does these capacities above seem right for the Teclast 64 GB tablet ?

thanks

32GB on each side so it's fine since ~38.0 GB (Win) + 16.53 GB (And) + Recovery Partition = 64GB :cowboy:

Hi everybody,
This week, I knew Teclast has a new X98 PRO international version different to the sold one from China. They closed a new International version for EU specially. So, it looks like, they will have 2 international versions. They will launch the new one on Sept 27Th and this new version has not Chinese apks, it has new apks, several new free accesories what I do not know yet, European warranty,…. I work in a media in EU and we received it. They will sell from Spain to EU (www.teclast.es) as I can see on www.teclast.com. Upon my point of view, this step from Teclast is very, very interesting for EU people. I will pay attention to teclast.es in order to see the new presale.

LATEST BIOS 2.05 Works on all Teclast X98 Air II & 3G

https://mega.nz/#!wgBjEbrI!Bn1HY_iSynNjpzE9Glsp3-5fcip7XfAge8HXhHph9gY


I'd really like if someone could tell me if the Front Camera work in Windows on HG6N HG5N and others.
This way I will know if I have to fix the DSDT table in the BIOS or NOT

Front Camera did not work under Windows with HG6N HG5N like the 2.02 BIOS It's confirmed !

In few days I will post an Updated BIOS to Fix the Front Camera bug under Windows with HG6N HG5N and others.
Other than the Win Bug it work fine so let's test it ! ;)

Enjoy and thanks to @fresnillo for the tip ! :good::good::good:

After a week or so with 2.05 I have gone back to 2.02. It appears that there is some problem with power management - my tablet kept on switching off rather than go into connected standby. I checked all power settings, and reset "balanced" to default but that did not help. Maybe more changes are needed to DSDT?

HDMI Output on Lollipop

Hi Guys

I tried posting this in the main teclast air 3G thread but couldn't get much traction there. Hoping someone here may have some advice.

I'm currently on merek's version 4.1 on my Air II and have no complaints. I do have one question though related to the HDMI out. When in windows 8.1, I plug in the cable and it automatically detects the connection and outputs a fullscreen 1080p image to my tv. This is what I would expect. When I plug in the cable for android (mirek190 v4.1) it also detects the presence of the plug but it does not adjust the resolution properly to my tv. What I see is basically a square box in the middle of my tv instead of a full screen 1080p image.

Is there a tweak or file i need to flash to correct this? Should I use the included resolution changer app and if so what settings should I use?

Thanks in advance

And how is your work in progress status @Mikha777 ? :)

I had to take a break my X98 crashed in the update from Win 8 to Win 10... Windows was throwing me a generic error and finally it was the partition tables that were corrupted.

Short story: X98 is fine now I'm finishing the configuration on Win10 (Updates + customizations + Image Backup) so in 2 day I will resume the test. So far it's look good one DSDT modification was crashing completely and the last I have tested was throwing a BSOD with a error message so I know a little bit more were the problem is.

Next step is to make smaller changes on the DSDT to better troubleshot what is causing the crash. :p

---------- Post added at 06:35 PM ---------- Previous post was at 06:27 PM ----------

I was afraid you'd say that?! Is there anything I can do to provide debug information? I'm happy to try again. Note I'm using an HG6M (originally Android only).

I would delete the drivers related to sleeping mode via the "devices manager". I'm pretty sure it is related to drivers/ACPI or even a corrupt registry entry. That's why deleting the drivers should reset completely the registry keys involved. :cool:

Hey guys,
I'm a more or less proud owner(a bit more less, it was an emergency deal short before the X98 Pro reched the market) of an Air II HG9M and I was wondering about something... is it actually possible to install Android-x86 let's say "out-of-the-box"/" just like that" on my device and if not how hard could this task be? I'm a bit outdated on this topic, so maaaybe...I might imagine it - the preperation process and so on - a liiitle bit tooo easy (that's why I ask).

    Easy Windows 8.1 install on a Teclast X98 Air II Android Tablet...

    I successfully installed Windows 8.1 Bing & Pro versions on my Teclast X98 Air II using the files & drivers straight from Teclast. Everything is working 100%! I will post instructions in a bit...


    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!

    I have a Teclast x98 Air II (HG7N) with dual boot from factory.
    I want to update the bios to bypass the battery drain problem. However it's not being easy to find the correct bios and not brick the tablet.
    I think it is one of these:
    -Dualboot Bios Tested C6J6 And C8J7
    -X98 Air 3G Air II Dual Boot Bios Flasher bat

    Both files are from techtablets.

    Someone can help?
    Confirmation that 2.02 works on Air II models:
    http://forum.xda-developers.com/showpost.php?p=61195478&postcount=806

    1. Download the file here:
    2.02 BIOS
    2. Extract the archive to a folder on your Windows host PC (One with adb installed).
    3. Boot your tablet into android.
    4. Enable USB debugging if not already enabled.
    5. Connect your tablet to the windows host PC via USB
    6. Launch windows task manager. Kill any running adb processes.
    7. Open a command prompt (non admin). Navigate to the folder where you extracted the archive.
    8. TYPE FLASH.BAT + ENTER
    You will see:
    ***********************************************
    * Tool to flash BIOS *
    * created *
    * *
    * 2015.4.23 *
    ***********************************************

    IMPORTANT !
    - Your device must be charged at least to 50 !!
    - Your device must be connected to PC via USB
    - In android - settings - developer options - check USB debugging !

    If above is ready - press any key


    9. Press a key to proceed. You will see:
    1 Flash System with partitioning
    2 Flashing BIOS

    choce[1-2]Enter:


    10. Type 2 + ENTER
    11. Wait for the BIOS flashing script to indicate flashing is complete.
    12. Hold the power button until your tablet powers off. Disconnect tablet from PC.
    13. wait 30 seconds and power back up while holding vol+.
    14. Select your OS and you are done

    hi!
    Here is the bios file for the x98 air ii

    Was successfully able to get my HG5N (originally android) tablet to win 8.1 w/ Bing and ACTIVATED via KMS.

    Stumbled across this guide w/ key included: h t t p : / / pan.baidu.com/s/1bncpRLP

    I couldn't read it, so I kind of guestimated the instructions... but here's what I did:

    1. Set the tablet into airplane mode (don't know if its necessary, kinda figured I shouldn't be on wifi for the process?)
    2. Go to the control panel and select "add features to windows 8.1"
    3. Select "I have a key"
    4. Input the key from the guide.
    5. Let windows do its thing, it'll restart twice if I remember correctly.
    6. Run KMS8 ( Get it here: h t t p : / / pan.baidu.com/s/1ntDjsTF - Password: 7pvy)
    7. Should say success... go ahead and turn on wifi, and enjoy

    8. Wait for the crazy good folks in here to find a way to enable dual booting (shouldn't take long - looks like teclast is already doing that w/ a new "version" - hoping its just a bios + rom to flash)

    8 part 2. Wait for someone to get lollipop on this :)

    *** 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.
