yes thats true. intel turbo mode off doesnt effect the GPU performance so much, but for some games and applications(especialy in Windows) which want a high cpu speed for performance, then it matters.. Lets wait a bit more if Teclast will do really something or not

Help please

Again please help! The tablet was fixed, and the reason is the battery discharge to 0, and enough power device, you need 3 amps. Now have 2 bug: 1)Windows does not show the battery charging, although the percentage is growing , but the charge is very slow 2)can't flash android via flashtool, all time stops at 11%, here's a screenshot of the error:htt ps://w ww.media fire.com/?dhqwdnf inklaa38

In dnx writes error "couldnt find device handle" and the sound off usb and the tablet goes into droidboot, then nothing... the Version I have dualboot

Android hangs on the label, intel, because I deleted the Chinese launcher

The reason is computerr does not see the tablet in droidboot, the driver used to work, now stopped, delete does not help

From my experience, I have to turn off this tablet before charging. Mine is c9j7 version.

If it still in on position , i.e. charging while running windows, it won't charge at all.
[Teclast X98 Air 3G] Revan1985:
No, tablet starts always with Android but i saw that the partition is small, 10 GB, so there is yet the windows partition. I don't know if there's a way to enter into the boot program when tablet start's, like enter in bios into Pc.

And if i try to reinstall dual boot, does dual boot see os already installed?

[Teclast X98 Air 3G] rad3d:
I'm not sure if you are looking for this?:

If you attach a usb-keyboard you can get into the BIOS and change some settings (like boot Hybrid, hotkey only) or go into UEFI shell. In my case that didn't work.

After turning the tablet on with the keyboard attached you must enter del or esc directly and it will put you into bios setup.

I'm not sure how you would install dual boot. In my case I doubt if that works because the UEFI seems to be broken somehow.

For those who aren't seeing the boot menu at startup and don't know how to open it, hold volume up when you press the power button, and keep it held down until you see the dual-boot menu.

Hey guys I have a problem with the Video playback on this tablet. Its a Teclast X98 Air II

When watching twitch streams or YouTube videos (or whatever, doesn't matter) the tablet just freezes and if I force close after that any videos will look laggy until I restart the tablet, I just can enjoy 5 minutes of video every time.

I went into the BIOS and disabled the Turbo (I think I did, it was under CPU options, someone confirm me how the turbo option is exactly called) and nothing changed.

If someone has a solution I can offer a reward for it, I'm kinda desperate.

A new problem I encountered with my X89 AIR II.

1. Android Rom installed (jcespi2005 Lite ROM - HG6M)

2. Windows installed (Stock Windows from Telcast- HG6M) - Two USBs (WINPE & images)

3. Windows seems working fine. No inverted screen. Camera worked right.

4. Android DISAPPEARED !!!!!!

OMG. Do I have to install ANDROID again ?

Dual Boot screen is still working but no Android Icon.

What shall I do?

This is the confirmation that there isn't any bug with the sw dumb.

Sw and HD dumb haven't problems.

The solution is to mod bios to make it work on every tablet or wait that teclast share a 'virgin' (never loaded) bios

No one app can allow us voltage control, because the kernel cannot permit it.

If we have the source, we can make a custom kernel with more governor and voltage control

Display brightness throttling

I think I found a way to prevent that the display is heavily dimmed due to a thermal event. It is in thermal_throttle_config.xml in system/etc. My interpretation is that by the mod below the brightness reduction is not immediately to 40 percent but goes down in steps to 80 60 40. Wouldn't you agree? I have not found the trigger settings yet though. The xml is editable (I use total commander), reboot afterwards. I will test some more. Of course such thermal mods are not without risk, so be warned..

[Teclast X98 Air 3G] Miles Wolf:
Hi there everybody! Here's a new user of the X98 Air 3G!

One question, is there any way to get a clean ISO of Widnwos 8 with Bing? Maybe I am a bit paranoic, but I would like to avoid any possibility of having any preinstalled chinese spy software doing a clean install, so I would need the ISO and the drivers separately. Is it difficult to do or it's like with any normal computer?

Bios info

Hi all merry Xmas , just a question , if you bios your devise what does it do to it please , I have rooted my devices and flashed a new rom and also done the Google play fix all on android , not bothered about the dual boot , I just wanting to know what happens extra to your tablet if you bios it ?? I still have chinese apps on that I dont want but just put them all in a folder and put them out way so kids can't mess with them , the tablet seems to be working ok , only one message I get when playing games is because temp lower throttle brightness apart from that all seems fine cheers Andy
[Teclast X98 Air 3G] Petepe10:
Bios will not give you anything extra. If you have fixed Play, you probably have Linksd installed, so that you can remove the chinese apps. Do not remove tUI before you install an alternative browser like Nova or Go or Google launcher. And I prefer CM browser over stock, snappier.

I also have the brightness messages, see earlier post today. Max brightness 40% is very low under bright conditions.

No, as Windows asked SIGNING-IN and rebooted the system, it's already gone.

I tried twice already. Android is gone as I installed Windows.

I didn't do anything but followed the guide for Windows Installation with two USB sticks (WINPE and images).

Windows may destroy and delete Android automatically.

As I install Android again, Windows is gone vice versa . :rolleyes:

I only used one USB stick (with Windows files) and a mouse for dual boot installation. Luckily my Dell is a huge USB hub. :D

Nice to see you back, hope all is okay!
[Teclast X98 Air 3G] kinhvanhoa:
I previously installed Windows with one stick as suggested on the front page but the windows didn't work properly.

This time, I tried to use a different image which is basically a stock Windows image on Air II (HG6M).

It's bigger than 4GB. Thus, I have to use two sticks-one for WINPE and the other for images.

This windows installation actually destroyed Android partition automatically.

I didn't even have any chance to save Android.

If I tried to install Android on the system (5GB partition), Windows is gone vice versa.

Strangely, as I checked the storage information on Windows (C:), there is 22GB available, which means " C:" consumes all stroage on internal memory.

Is that a problem of WINPE? Or is the matter of DUAL BIOS?

Anyway, Andorid and Windows seem work fine for the first time but they don't share the partition with the Dual Bios.

I have the problem with the 3d games, it freezes everytime I play a game. I tried the turbo mode off and it worked but not every time. moreover I don't want to have my tablet with less power.

Is there any other way of fixing it?

Will teclast bring any other bios for the tablet?

[Teclast X98 Air 3G] mohamad_skiller:
do this it must be solved your problem

i have this problem but i can solved it

First of all install all intel driver in first post and make you sure your pc recognize your tablet

Then just open manufacture tools open file menu go to the setting

Put this value to( SoC Devices: VID: 8087 PID:0A65)

Put this value to ( Androird Device: VID: 8087 PID: 09EF )

this vid pid must work just on c6j6

apply and ok it

- Disconnect the USB cable from the tablet and turn off your tablet (important)

then in Intel Manufacturing Tool and go to the menu File -> Open. There, choose the folder of ROM (X98_Air_3G_ (C6J6)), find the file "flash.xml" and open it.

you keep the tablet down the VOL +, VOL- and POWER until goto the dnx mode , connect the USB cable and Intel Manufacturing Tool begins the process of flashing Android ROM. Wait until the process is complete, disconnect the tablet from the USB and and turn of your tablet . connect the usb keyboard to the tablet and turn on your tablet you get shell command error again you just type exit and you see the tablet goto the android version when goto the android you must change your bios with ifwiupdate you can flash dualboot bios or new android bios from first post

Fixed the bootmenu by installing quick boot (from play store) in Android then running that and select Go to recovery mode. That didn't seem to start. However when booting with power and volume+ pressed I managed to get into the dual boot screen.

I've run windows and restarted it. It came back into the boot selection menu (android or windows) again. So it seems to be alright again.

So I finally got my hands on an Air II, got it dual-booting, everything's mostly good... but I think I might have a defective headphone jack. With music, it sounds like it's being played through a tunnel, or been compressed down to something like 8kbps. The main instrument tracks usually sound fine, but the vocal track is heavily muted and in some tracks practically inaudible; it's also tinny and a bit distorted. At first I thought it was just an issue with the default settings in Android but it's still happening in Windows. Everything sounds fine through the speakers. Has anyone had a similar issue and found a fix, or should I look into getting an exchange?
[Teclast X98 Air 3G] Hendrickson:
It's not defective, it's a Iphone style jack, if you don't fully insert your 3.5 plug it will sound normal. Or use a headphone without a mic or a converter like this one: http://www.ebay.com/itm/301385140519?_trksid=p2060778.m1438.l2649&ssPageName=STRK:MEBIDX:IT

I was trying to change the resolution but it didn't help. The problem is the same under windows 8 and the android.

Do you think that I have a wrong cable or the damaged hdmi output?

I'm still suffering from battery drain under the windows. I was looking for the solution and I find something that should extand the battery life when tablet is on sleeping mode.

1. You should check there is nothing draing the battery under sleep by sleepstudy report. In my case I didn't find anything.

2. Then go to task menager>services>open services>scroll down for windows search>properties> and set startup type to disabled>then click stop> and apply. The battery working time should extend now.

3. You can also use the ParkControl program to switch of 2 of 4 cores it will extend the battery life, but slow down your tablet.

In my opinion the drain issue is caused by the dual BIOS faulty or another possibility- the faulty drivers. I'm using the polish iso of windows 8 with manually installed drivers I had install all of updates, but it didn't help. I want try the originall teclast windows 8 with bing but this link from first page didn't work.

Could someone upload this again?
