inutile a particcipare qua piu, e' diventato un "chat room"
[Teclast X98 Air 3G] krisbliz:
First thanks for all the effort that you give for this. I made batch file for the problem when switching android to windows and you get inverted touch. The bat file just reinstalls the "Goodix Touch HID" and everything works like it should before you login.

These are the steps and the package needed for that task.

1.So first copy the files in Windows dir

2.now run gpedit.msc

3.computer configuration

4.scripts (startup/shutdown)

5.startup

6.add

7.browse for reset driver.bat

Thats all

If you want you can add to your guide.

[MENTION=6211390]PWMx[/MENTION], do you think that there might be spot SOC overheat? I mean... my tablet freezes all the time with 3D stuff. Today when I woke up the ambient temperature was about 20 deg C, tablet was cold, I ran OpenGL 3.0 benchmark and it freezed after ca 15 seconds. The back lid was not warm at all, so I think that it might be some spot overheat, what do you think? Unless it's not only a matter of overheating...

If I turned off turbo mode and switched these chipset settings (mentioned few posts ago - with old bios screenshots), my OpenGL 3.0 benchmark ran for the very first time, but the overall performance was poor.
[Teclast X98 Air 3G] petruccig:
keep calm and power on Teclast X98 Air 3G

I've updated the post #4 and #3 with krisbliz's work and keepfishes's work. However I had updated the post #4 at 1 pm.

Please, before to post new questions it's better to check if the first four posts were just updated.

If you see something wrong in our tutorials or you have difficulty understanding some steps, please advice to us so we try to correct or help you.

Thanks a lot

You can choose what partition to install Windows. On automated installations probably takes ALL the disk, deleting the Android installed.

So my advice, take a original Win 8.1 ISO and make a USB with RUFUS, and install the drivers later ;) Or make an ISO from your DVD with drivers includede with WinToolkit, and generate the USB as before...

[Teclast X98 Air 3G] SUMMERBREEZE:
Yes exaclty the same thing happened. When i do those setting in bios and turned the CPU Turbo mode off, i can play any game or run that OpenGL 3.0 benchmark with no problem! But CPU now works max at 1.33 ghz which is a huge difference than max 2.16 ghz! This tablet can not handle the Turbo mode.. i think the cpu/gpu voltages are not enough for this..

---------- Post added at 06:02 PM ---------- Previous post was at 05:52 PM ----------

Please try the bios settings above. But just be careful that you are doing the same thing and F4 & Save-Exit

And try the games and opengl 3.0 benchmark once more. But please all before these, do a benchmark with Antutu 5 and make a screenshoot of the bench score.. And do the settings as above and do another benchmark with Antutu 5 and make another screenshot and share with us.

Windows10 very smooth

Hi all,

got mine today and been running Windows 10 for a few hours now. very smooth only problem is the inverted camera and some windows bugs due to win 10 being a preview.

For those wondering win 10 bootable usb would not boot had to boot with the winpe provided on first post and run setup from command prompt. drivers installed manually and after that all working good. only other small issue is that when turning the tablet is a bit slow in turning the screen but nothing major.
[Teclast X98 Air 3G] Hendrickson:
I've been reading into that thread and the guys there have extracted the driver from teh Air II (working correctly) and then installed it in the Air 3G and its still upside down. They seemd to think its not the driver, but linked to the gravity sensor or a bios updated is needed. I have a feelign it may never be fixed as Teclast don't really seem to care. And they will only just pump out more models and move on.
[Teclast X98 Air 3G] pinorino:
Hello, sorry for my English, as I understand it there are no problems (camera in reverse, and 48Hz) devices purchased directly with Win 8 installed.

Can you tell me if the Teclast X98 Air 3G (Android) on the same hardware as the Teclast Air II Win 8? In Teclast Air II Windows 8 are the 3G and GPS? Thanks.
[Teclast X98 Air 3G] BoORDeL:
AIR II has no gps and 3g but it doesn't suffer of reverted camera.

Don't know about 48Hz problem.
[Teclast X98 Air 3G] tumich91:
The best choice is Teclast X98 3G. (Not Air). He has no problem with refresh rate and with camera. I regret that I mentioned it to a newer.

Anyone know tablet with 9,7" and Retina + Gps+windows for 200$~?
[Teclast X98 Air 3G] vgiozo:
Is it possible that Teclast has updated the drivers on the tablets it ships with preinstalled Windows but has not yet released those drivers to the public?

X98 Air 3g + Windows is now being advertised in TEclast's official page but also available for purchase from some retailers, like here, here, here and here.

Too bad no one has received it yet to be able to tell us if the same bugs are there.

I want to buy the tablet to run with windows exclusively, but not if I am gonna be stuck with a bad driver...so the other option is x98 Air II (which as you say does not suffer from these bugs on Win8.1), but unfortunately it lacks GPS and 3G
[Teclast X98 Air 3G] ambrosio5:
Hi again,

When you say clean install I guess you mean that you placed the Win 8.1 Pro ISO in a USB stick, booted from it and made a full clean install, is that correct?

I mean you didn't follow the teclast method with the 2 sticks on a hub since you already had the win BIOS....
[Teclast X98 Air 3G] vgiozo:
It could be that my Antivirus program is wrong, but

the "WINDOWS 8.1 WITH BING (Teclast beta version - no driver nedeed)" link is detected as including a virus, named Gen:Variant.Kazy.168772

I read here that the above virus name corresponds to the trojan Vundo

[Teclast X98 Air 3G] ambrosio5:
I wonder i the X98 Air 3G version with preinstalled Windows has a different ID than (C6J6) thus meaning a different download site on teclast....
[Teclast X98 Air 3G] vgiozo:
Yeah I am wondering that myself...

On the tinydeal and aliexpress links I provided above all items are actually *pre-orders* but they are both certain to get the merchandise by the end of next week the latest, so they can start shipping around November 20th.

Perhaps we could ask them to check and tell us. Is the ID written on the back of the tablet or somewhere?
[Teclast X98 Air 3G] ambrosio5:
Yes it's on the back of the tablet as in the preinstalled with Android version (C6J6)....
[Teclast X98 Air 3G] BoORDeL:
Yes, just one usb stick.
[Teclast X98 Air 3G] keepfishes:
Hey guys,

I read this thread about the camera problem, I do understand Chinese and I'll translate it for those who don't know (please add the "h" to the link below, I'm new and I can't post links): ttp://bbs.teclast.com/thread-256976-1-1.html

Basically what he's saying is that the camera drivers for the Air II and Air 3g are identical, and the image rotation happens only during use of the camera app, but when using apps like QQ the rotation doesn't happen.

I have a link to the driver:

ttp://pan.baidu.com/s/1jGJwMbk

Password: 0292

Reading further on, there are some others who commented that it might be a BIOS problem. Also, others say that even on the X98 Air II, only on the pre-installed Windows version does the camera work fine, but when Windows is modified and run on the Android platform (I think they mean dual booting with virtualisation), the camera problems occur on the Air II as well. Also, there is one comment saying that the Win 8 version of the Air II has no problems when using the camera app, but the camera is left to right inverted when using the QQ app.

Then there are couple other comments reporting no problems on the camera app but a left to right inversion of the image on the QQ app on the Air 3G.

They also posted a camera test app:

ttp://bbs.teclast.com/forum.php?mod=attachment&aid=MTA0MDIzfDc4YTkwODRhfDE0MTU1MzgyMzN8NDY5NTcwfDI1Njk3Ng%3D%3D

In summary, here is my take: On the same device, if the image taken by the camera app is normal, another app that takes images like QQ will be problematic, and vice versa. And this problem seems to affect both Air 3G and Air II. Also, some devices have images that are inverted left to right, and others up and down.

Can someone elaborate on what the 48Hz refresh rate problem is about? Maybe I can look on the Chinese forums to see if they solved it.

Thanks!
[Teclast X98 Air 3G] BoORDeL:
Really thank you so much.

It seems that 48Hz problem could be a driver issue (from INTEL) or a bad implementation of 32BIT uefi BIOS for WINDOWS 8.

The problem doesn't occour on android or linux or windos xp using 64bit uefi bios.
[Teclast X98 Air 3G] vgiozo:
I think we need someone who can read chinese.

About the 48Hz refresh rate...it seems that it is a windows gpu driver issue, evident when playing 3d games...there were some serious touch screen issues that seemed to be related as well.

One person mentioned that before installing the gpu driver in windows refresh rate was fine, but after it locked at 48hz

I have dual bios and I prefere windows. Changing bios and bios setting is not sollution for me.
[Teclast X98 Air 3G] ImJamIN:
We know that problems of overheating are present only on android. So I think that we must work on a solution on android and not on bios (disable turbo etc.) Because on windows we haven't any freeze on 3D games.

Well, we must try to change governor and voltage with external programs like system tuner and trickster. Or some like have (partial) done with onda v975, try to make a custom kernel with Intel sources.

of course there is a normal 1-OS support BIOS, this is the official bios from Teclast website, you can check the attach

here you can find :

http://d-h.st/Lmor

I think you know how to flash bios under windows.. so maybe you can try these settings under old bios and try the games again. If everything goes fine, we can easily say ''Intel Turbo MODE'' is the mother of these problem, and later you can go back dual bios if you like.

BUT if you have android and windows at the same time, i dont know how to do it after the bios update? i mean the bios wont be the dual boot one but you will have 2 different OS.. complicated

[Teclast X98 Air 3G] SUMMERBREEZE:
good luck!

We also found the GPU freeze issues on gaming, the Intel Turbo Mode causes it. Tablet and propably the voltages for GPU/CPU can not handle the immediate changes.
[Teclast X98 Air 3G] PWMx:
Those 25x25mm pieces are quite small. It would be easier to apply 40x40mm or even better 40x100mm (as I did).

The benefit of larger pad is that the 3G modem etc. gets also cooled.

And with 25x25mm pieces you would need to remove those flex connetors and lift the board more in order to place several pieces.

The material is probably suitable - And there are plenty of offerings for 4cm wide tapes and 40x40mm and larger pieces ...

Just make sure that it's not too thick ...

It's difficult to say more specifically exactly what will work unless one tries it out.
[Teclast X98 Air 3G] jacfry:
You can find my post about it somewhere in the thread. If you can live with camera inverted you can update intel display drivers and Asphalt 8 will work much better. It will still freeze once in a while but usually I don't play that long :)

[Teclast X98 Air 3G] PWMx:
I my case there were quite often those thermal warnings. Heavy 3D apps did freeze or cause reboot after few minutes (max 15 or so).

The tablet didn't get noticeably warm on external surfaces.

After the thermal adhesive underneath the circuit board / on display back side there has bee zero thermal warnings, freezes or reboots.

I have now been continuously running heavy 3D apps and benchmarks for one full day.

The tablet exterior gets now really noticeably warm on both display and back side.

So, It's up to you whether you would like to get the full performance by applying thermal adhesives

or try to stabilize via some BIOS or other SW settings while reducing the performance.

(And of course you can try both !)

You simply don't know until you try .. Or we get several more results, that is.
[Teclast X98 Air 3G] acc007:
The last sentence is crucial in my opinion. Looks like SOC is overheating but due to pure thermal design this heat is not transfered to the aluminium back lid and it causes freezes.

However in my case 3d test freezes no matter if tablet itself is cool (like this morning) or warm (eg after 2h of simple 2d usage)

How thick is your tape? I think you mentioned 0.1mm would be ok, right? So all these 1mm thermopads will simply not fit...
[Teclast X98 Air 3G] PWMx:
I don't think it needs to be electrically insulating tape.

Definitely not on top of the can lid. Probably there are not exposed signals underneath the board.

(I didn't look closely back side of the board. And my sheet wasn't perfectly insulating ...)

After re-reading some of those ebay notices I think they mean to warn it is not a substitute for thermal paste etc.

I.e. will fry if used with chips dissipating several hundred watts !!

Just keep it thin enough - There are plenty of options below 0.2mm thickness.

And pretty much anything is better than narrow air gap as it is now.

I wouldn't be amazed to find out that the working devices have some adhesive sheet there ..

Or othervise have better thermal contact.

http://translate.google.com/transla...=http://bbs.imp3.net/thread-11198989-1-1.html

I wonder if it's just poor thermal design in the tablets or if Intel is offloading the lower quality chips to China (as they are basically selling them at a loss for market share right now). I haven't seen any similar complaints from the non-Chinese designed brands.
