Thank you!

I used the stock windows image and 2 usb drive method of install on my android X98 air 2, works great. I updated the video drivers with that intel driver update tool, but the newest drivers broke hardware decoding on Steam In-Home Streaming for me. When I uninstalled those drivers and installed the included stock drivers, I can do in-home streaming again!

Now the only thing left for me to do is fix that upside down camera... might not bother until a better fix comes out

In general, microSD cards have pretty poor read/write rates. I'd recommend trying a class 10 or UHS card, and even then the speed will only be a fraction of a platter-based HDD.

For what it's worth, I just flashed my stock HG6M (4.4.4) using IFWIUpdater, no problem. I was a bit hesitant about flashing an Air 3G BIOS to an Air II, but I figured that it's basically identical hardware minus the 3G antenna anyways. Comfortably dual-booting the debloated rom posted here the other day along with Windows Technical Preview, no real issues.

Ubuntu / Linux experiences with Teclast X98 Air2 HG6M

HOWTO create an UEFI USB-Stick with Linux wich can be bootet from Dualboot-Bios:

(Attention: The X98 only boots from a GPT EFI Stick in 32bit and has to be in Windows-BIOS-Mode!)

Possibility #1 (with Linux):

1) If Stick is sdb, do a dd if=/dev/zero of=/dev/sdb to clean it

2) gdisk /dev/sdb and create a new GPT-Table with one Partition (sdb1) with Type 0700

3) mkdosfs -F32 /dev/sdb1

4) mount /dev/sdb1 to /mp1 f. e.

5) mkdir -p /mp1/EFI/BOOT

6) cp -a bootia32.efi /mp1/EFI/BOOT/ (use google to find and download it from github)

7) mkdir -p /mp1/boot/grub/

8) confiugure and put a grub.cfg to /mp1/boot/grub/

9) Now You can boot YOUR configured Kernel an initrd from USB.

My Stick looks like this:

./EFI
./EFI/BOOT
./EFI/BOOT/bootia32.efi
./boot
./boot/grub
./boot/grub/grub.cfg
./boot/grub/font.pf2
./SysRes441
./SysRes441/sysrcd.dat
./SysRes441/rescue32
./SysRes441/initram.igz

Missing Files are from the SysResCD 4.4.1 from here:

https://sourceforge.net/projects/sy...6/4.4.1/systemrescuecd-x86-4.4.1.iso/download

And my grub.cfg:

if loadfont /boot/grub/font.pf2 ; then
set gfxmode=auto
insmod efi_gop
insmod efi_uga
insmod gfxterm
terminal_output gfxterm
fi

set menu_color_normal=white/black
set menu_color_highlight=black/light-gray

menuentry "Sysrescd 32bit" {
set gfxpayload=keep
linux /SysRes441/rescue32 subdir=SysRes441
initrd /SysRes441/initram.igz
}

Possibility #2 (with Windows):

1) Take Rufus from here:

https://rufus.akeo.ie/downloads/rufus-1.4.12.exe

2) Download Ubuntu 14.10 64bit from here:

http://releases.ubuntu.com/14.10/ubuntu-14.10-desktop-amd64.iso

3) Start Rufus.exe and first select the Ubunuto-ISO, then secondly change the Boot-Type to "GPT for EFI-Boot only" and FAT32 on the selected USB-Stick

4) Start the process and wait til done

5) after that maybe You have to put the /EFI/BOOT/bootia32.efi (see above) to the stick

6) now you can boot the Stick but be very very patient, because you will get many IO Errors for some /dev/mmcbkl-IDs, but Ubuntu will start, X-Server inclusive!

After this I did a full Backup of my X98-Harddisk: dd if=/dev/mmcblk0 of=/mp2/x98-backup.dd (32GB)

I have the same problem i flashed the bios and now i have the problem that the teclast air || dont boot from the usb-sticks.

I'm afraid that i broke ;/ would somebody be so kind and tell my what i did wrong.

I used the guide from JonMichaels which seams to work for other people.

i have a HG5N not a HG6M

best regards

[Teclast X98 Air 3G] FEGuy:
Did you manage to get a system that'd install and boot, or just something half-working from a stick? There's a post on the Teclast forums about getting a running 14.04 64-bit install, but given the way the dual-boot BIOS is about booting from USB after Windows is installed, it's taking a bit of tweaking to get everything going, if I've even interpreted the instructions correctly.
[Teclast X98 Air 3G] cc-band:
Currently it is only half-working ...

I did not find this thread You described. My final aim is to install Ubuntu permanently!
[Teclast X98 Air 3G] FEGuy:
http://bbs.teclast.com/thread-255275-1-1.html

From what I can gather, it was done from an Android-only Air 3G. Google translated instructions below, if you don't want to register and reply to the thread to view them:

1, need http://bbs.teclast.com/thread-254655-1-1.html start inside this method A WinPE enter the system, open DiskGenius.exe, to delete all partitions, the first partition 1G build a fat32 partition sizes

2 to http://pan.baidu.com/s/1qWwj248 download my compiled grub2 boot files, unzip the / efi entire folder to a fat32 partition on the root directory

3, to http://ubuntu-china.cn/download download 64 of ubuntu system ubuntukylin-14.04-Desktop-amd64.iso

4, after downloading, use winrar to open, the inside /casper/initrd.lz, /casper/vmlinuz.efi extract from it into the root directory of the first partition, do not bring catalogs, direct discharge initrd.lz and vmlinuz.efi to the root directory of the first partition

5, the "ubuntukylin-14.04-desktop-amd64.iso "renamed" u.iso "(easy to type commands), also copied to the first partition

6, these are somehow, shutdown restart, entered the GRUB menu, press C to enter the command line

1) Input: "set root = (hd0, gpt *) "carriage return (without the quotes, the following is the same), according to the actual situation where the * to u.iso partition number, usually within 1-10 have to try, you can enter the" ls " command to see what are the partition

2) then enter "linux /vmlinuz.efi boot = casper iso-scan / filename = / u.iso ro quiet splash" Enter

3) then enter "initrd /initrd.lz" Enter

4) then enter the "boot" Enter

5) all goes entered the ubuntu system, and click the Install button to the left or the desktop "Install Ubuntu" button you can install, and follow the prompts to install step by step. About WindowsXP, currently only in the vmware ubuntu running inside, because the motherboard only supports pure uefi

Thanks! This would be Possibility #3 :) Maybe You give #2 a try. It seems to be easier.

The only thing i think of is, what are the special things of Kylin-Ubuntu?
[Teclast X98 Air 3G] tirmey:
Hi, everyone! Windows ROM have the same freeze issues as android in Teclast air II?
[Teclast X98 Air 3G] FEGuy:
In theory, it's not that different from using the Rufus method; a few modified files and a couple commands in GRUB to boot the ISO directly from the local drive rather than USB. You shouldn't have to go through the WinPE process - just make a new partition on the drive, use a USB stick, etc. In practice, I cant tell if it boots or not - with a standard 14.04 ISO GRUB says it can't a suitable video mode and tries a blind boot.

I assume Kylin is a version of Ubuntu modified to comply with Chinese regulations, etc., but there might be some other differences if it booted and installed with minimal hassle as opposed to standard Ubuntu ISOs. Or I could just be overthinking things and there's a dozen other reasons I can't get things to work.
[Teclast X98 Air 3G] PDPR:
Yes, bad luck.

I have still to wait until eeprom & cable arrive home. Zerocinfig member (and others) succeded into reflashing again histablet, I`m waiting for his tutorial too.

Hello,

I want to buy Teclast x98 Air II and flash Windows 8. But i read laggy touch response issues and other things. Do you recommed this tablet for Windows use? I don't want dual boot and Android. It seems Onda v975w is better choice for out of the box Windows experience but Teclast's hardware and specs are better. So I'm little bit confused.
[Teclast X98 Air 3G] matic007:
Ok so I received my teclast air 2 but its a HG6M, I want to flash it to windows 8.1 but after reading all these threads I'm a little confused: whats the best guide to flash my tablet to windows 8.1?? Please help, thanks!
[Teclast X98 Air 3G] FEGuy:
So far, by following the Chinese instructions and using thier ISO, I've made it as far as Ubuntu's splash screen a few times, but never any farther. Once I got generic I/O errors from hitting the power button right before things started happening, one hang on a 'scanning for btrfs filesystem' message, and once I just gave up after it started throwing r/w errors on just about every block of the memory. I might try some more tomorrow.

On another note, what do people recommend for a case/folio with a keyboard? I picked up a Logitech FabricSkin keyboard folio on clearance, but a) I can't activate the bluetooth keyboard, thanks to it relying on iPad magnets the X98 doesn't have, and b) the clip design means I either keep the USB and headphone jacks covered, or have the power/volume buttons pressed right against the case if it's stood up in keyboard mode (which I can't use anyways until I figure out how to trick the magnets). I've seen some generic cases with microUSB keyboards, but they've all got ugly strap systems.

Dual Bios file for Air II HG6M

Can anyone provide a verified link to Dual Bios flash rom file for x98 Air II HG6M revision. I just want to be sure before I go ahead and flash that it will work. I currently have single bios flashed booting to Windows 8.1 Pro. I dont mind if I have to repartition just need guidance on getting the proper bios file. I have been looking at various posts but no clear actual post of a bios file for the HG6M.
[Teclast X98 Air 3G] dimex:
I wish Teclast would make an Air II or Air II Mini (8") with an active digitizer. I would be in ****ing heaven.

Currently the Asus Vivotab Notr 8 is really the only one that fits the bill, but there's no dual boot (Android-x86 or otherwise) and probably wont be anytime soon.

If Teclast filled the pennable niche I truly think their sales would skyrocket.

And all needed files too ?
[Teclast X98 Air 3G] gangrel76547:
Nobody is making instructions for the Air II because the instructions would be exactly the same. The only difference between the 3G and the Air II is the Air II is missing the 3G radio and the GPS. If the instructions are too complicated for you then I don't know what to tell you. Those instructions contain everything you need to flash Windows, Android, or both to your tablet. Just read through them and take it slow.

Dual Boot finally works (but Bluetooth problem on Android)

Well, after a long and patient try to install Dual Boot system on my Air II, I finally have two OSes (Android and Windows) working seemingly fine on my device.

No camera issue. No Screen issue so far.

However, weirdly, the bluetooth on Android (windows works fine) doesn't recognize any devices while Windows does.

I installed the Stock Android rom signed as HG6M, which was modified by jcespi2005 for the dual bios available here,

and also installed the stock Windows (HG6M) with the modified some files for the dual boot.

The bluetooth problem on Android is something I didn't experience before though.

Any similar problem has been reported yet?

Anyway, the installing dual OSes is a really time-consuming job, especially for Windows (activation, removing horrible Zoomify malware....).

What I've learned so far is: the stock Windows does have correct drivers for Camera and Screen of AIR II.

DO NOT USE the Windows image available on another thread for AIR 3G. It won't work for AIR II.

Hmmm, I've just found that when I turn on "Bluetooth" on my Android, "Superuser granted an interactive shell."

I think this makes a problem but I don't know how to fix it.

Any helps? Thanks in advance.

SOLVED. SORRY for the mess.

Recently Teclast release an update for playstore issue, camera focus and others. For 3D games issue they just say might able / might not fix the problem.

Hi, new to the site and have a question about the dual boot process. I have the Android only x98 air ii with updated 4.4 android (HG6M) looking to see if I can add Windows 8.1. Before I read the install instructions and how to flash the bios, I used the IFWI Update app on the tablet to update to Android 4.4 and fix google play app. After the update now there's no IFWI Update app icon. I did not update to the dual bios*bin, but if Bios updated, how can I tell if the tablet has the dual bios? Can I re-flash to the dual bios using my PC?

Bios Flash - Estimated time?

I just received my Teclast x98 Air tablet and I'm attempting to make it dual boot.

I'm only on the first step, where I have to flash the dual boot bios using "UpdateIFWI".

But after selecting the bios file and hitting "Update", its been sitting on the "Updating this may take a few minutes.." screen for about 5 hours now.

I can't see anyone else mentioning how long this step takes, I would have though if it was meant to be this long that someone would have mentioned it.

If it is not meant to take this long, should I attempt to cancel the process somehow? I don't want to end up bricking the device, haven't even had a chance to play with it yet!
[Teclast X98 Air 3G] enestu:
Too long., It takes 5-15 minutes max. Don't power off the tablet try to reflash non dual boot Android firmware with UpdateIFWI.

Mine is bricked, I'm waiting hardware to reflash eeprom.

Your android is 4.4.2 or 4.4.4, have you updated your x98 before flashing ? It seems there's problems with version shipped with 4.4.2.

[Teclast X98 Air 3G] Jazah:
Mine came with 4.4.4

It actually didn't even have UpdateIWIFI on it when I got it, I had to find the apk for it on some Chinese website. (Probably why it didn't work)

After about 6 hours of sitting on that screen I pressed the power button (not hold), and after turning it back on android was still usable.

I then followed the guide that details going from Android > Windows, which seemed to work fine. I've now got windows 10 running on it.

Later today I'll try and do the Dual Boot procedure again, but from windows instead of android.

As far as windows 10 goes (I haven't seen anyone really talk about it), all the drivers appear to work correctly and it runs fairly smooth.

The camera fix didn't need to be applied.

Touch is great for browsing the web (Internet Explorer), but clicking/double-clicking in windows explorer can sometimes be finicky.

Battery meter appeared to work correctly, was at 80% when I started and went down to about 20% after 4~ hours use.

Haven't tried any games yet, but videos work great.

Takes up about 7GB of space before any cleaning up is done.

After I get dual boot working I'll play around with it a bit more.

Update: Dual boot is working

Mine didn't have UpdateIFWI at all when I got it. It is possible you can follow the same procedure for flashing the windows BIOS, but for the dual BIOS instead, but I have no tested it. I can however confirm that if you install windows on the tablet, you can flash the dual bios through windows.
