Guys, I've got a stupid question and I don't recall it was anywhere in the thread. I've just received my tablet today and wanted to install google play fix, so first - to root it. So - I need to enable "USB Debugging" on the tablet. But no matter what I do, I can't do it. It's always inactive :(

I installed adb driver first (link from post #2), then uninstalled it and installed the drivers from X98 Toolbox. But still - no matter what I do, "USB debugging" in developer options is always greyed out. My tablet always connects in MTP mode and I can switch it to PTP only.

I didn't flash bios or android rom yet.

Guys does the camera fix work for any of you on dual bios? I get inverted touch and screen in windows after every os switch

Only way to make it stick but with camera inverted is using the teclast drivers
[Teclast X98 Air 3G] G3n3R4L:
this happens when you switch from windows to android, and then again when you come back from android to windows .... you will need to copy the touchsettings everytime you log into windows after android ....

so i installed the old drivers with inverted camera and they work good but the camera is inverted

edit: btw the teclast driver is more stable and smooth with windows use
[Teclast X98 Air 3G] heikkiap:
I am really not a Android specialist, but I think I had same problem before I flashed Win BIOS.

On the same "page" (or previous page) there was some option at the very top of the page, I had to choose something there. As I don't have Android now, I can't check it.

Haha welcome to the world of Chinese electronics. They are your best friend until you actually purchase something.

Like I said ages ago, I always buy Chinese electronics fully prepared to be disappointed and if its better than that, then thats a bonus :D

I dont know why some people can play some games and some cant, it is odd. I have read from Intel that a lot of 3d games are not supported yet.

Whether it is Intel that needs to make the improvements or the game developers, who knows.

I can run that benchmark for so long that I get bored and not get a freeze or crash, but cant even open RR3.

---------- Post added at 08:10 AM ---------- Previous post was at 08:02 AM ----------

So do you think it would be worth me using the dual boot bios for android only.

The battery drain is way lower in standby with 4.4.4 and the teclast bios than it was with 4.4.2, but any further improvements in battery life would be welcome.
[Teclast X98 Air 3G] SUMMERBREEZE:
Have you tested and played games in Android too? for example Real Racing 3, Dead Trigger 1, Asphalt 8 (each minimum 30 Minutes) and does your tablet pass this test (minimum 15 minutes repeat it)

HTTP://WWW.mediafire.com/download/faoerw8cx35ft88/com.Maniac.UBenchEnhanced.apk

Maybe in windows, the games will be much better and maybe less crash, maybe they will LOVE windows 8.1 achitecture more than android etc. but if we will have dual boot and android/windows 8.1 together but almost all heavy 3D games prolematic for me in android, then this is not a true dual boot for me anymore..
[Teclast X98 Air 3G] trikst3r:
Are you saying you'll upload your own win8.1 image with drivers, updates and EN/FR language pack? Cause that would be great, i have the Chinese image installed and there are lots of chinese leftover.

Hello guys,

I'm reading this thread from begining, since I was thinking about buying this tablet. I decided to buy the teclast x98 air 3g and I bought it on 11.11 sale. I received it on friday. I got C8J7 version with android.

Tablet is really great, fast and good quality for me, but it has cpu/gpu problems. First 3d unity test crashed after 5min. I tried also RR3, Beach buggy (which is lite game but crashing too) and Asphalt 8: Airborne (which works fine).

I read about changing the BIOS so I did it, but it doesn't help at all. I found one more problem with dual bios: When I power off the tablet I have problem to switch it on again, it wasn't responding, but battery was full, so I returned to BIOS from teclast site and now it is working fine.

I wrote a messenge to Anna Fang and they respond this:

I'm waiting for my usbhub, then I will install windows and test some steam games if it will crash I will open a dispute.

Maybe someone with cpu/gpu issues could try games on windows 8?

I also bought a microsd card (64GB) file format is exFat, but when I put it to the tablet it shows only messenge "Now you can remove your sdcard".

Any solution for this guys?

I got the same pop-up. I'm from PL btw
[Teclast X98 Air 3G] jcespi2005:

[Teclast X98 Air 3G] SUMMERBREEZE:
witam my friend to the our forum.

Yes unfortunately this CPU/GPU problems exist in the tablet. This is a fact. Some of the users here think it is not true but its just there. You are one of the victims of 11.11 sale. They sent the defected tablets or already returned tablets to people because they were promotional. This is really disgusting but it is.. All people who say they have problems with cpu/gpu also add they bought their tablets on 11.11 sale.. This can not be a considence, can it?

Please install windows 8.1 to your tablet and try some games (such asphalt, need for speed, fifa etc. i mean some heavy 3d games) and lets see it will crash or not.. Maybe these problems are only for Android, but still not acceptable.

We are looking forward the news from you. Witam jescze raz :good:

is strange, bec i flash right file on c6j6, and it was c6j6 show ... i dont know

but i u say is not very important ... is just a entry in build.prop ... made no difference ..
[Teclast X98 Air 3G] SUMMERBREEZE:
then your tablet is just fine and you are lucky my friend. Is it C8J7 yes? Is it possible to make some short videos please while you are playing those games? It will be very helpful when we open dispute.

Guys, if you have C8J7 device and you are android, Please pay attantion to my request and play the games (which gives error) and do small videos, even if they play just fine. In both ways(freezes or everything fine), we will have some proofs for dispute or refund requests.

Thank you

Same issue here

I've got the same issues (gpu/cpu crashes) on my tablet. I'm running 4.4.4 and 2.01 ROM, BIOS not upgraded yet but I'm afraid nothing gonna change wheter I stay using Android or W8.1.

I bought my gadget at TinyDeal on October 23th, (C6J6) I've wrote them an email and they told me that I have to send them a video showing the crashes while playing 3D games.

In my case everything sems to be ok but playing 3D games, tablet crashes running ANY game, it doen's matters heavy or light gpu use. RR3, Dead trigger, RR2, Asphalt, etc, etc.

I'll stay tunned and hope we can solve it in a peacefull way.
[Teclast X98 Air 3G] majkel_94:
One of us probably don't understand English...

I mean that this Android ROM has emulated sdcard. When you take a photo, the app write it into the /storage/emulated/0 partition, which is the symlink to /data partition.

So when you have 4GB /data and you make o movie, you reduce the place for apps.

Yes, I can use Link2SD and move apps to sd card. But many apps need additional files (RR3, Angry Birds, GPS navigation offline maps) which has to be in emulated sd card partiton. When you place it on your 64GB SD Card they can't find it.

And also you can't see in Windows movies or photos or other files saved in /storage/emulated/0 partition (default place for downloading and app folders) due to ext4 file system.

So we have to find a way (maybe Xposed module?) to disable the emulating feature or just hardlink emulated sd to external sd card!
[Teclast X98 Air 3G] robusto:
My c8j7 works perfectly.. No hiccups in games., its warming a bit which is natural.. On the win side, my touch is reversed, even though I tried deleting the touch file from the inc folder.. Was it some reg file that needed editing? I could take video of my x98 running 3dmark. I can't run dead trigger 2 at all, doesn't start
[Teclast X98 Air 3G] G3n3R4L:
all i did is editing the partition.tbl file, so it doesn't have emulated sd card .... and again when saying using link2sd to move the applications, this is english not "szlaczki"

[Teclast X98 Air 3G] mrbun9l3:
Did you make dualboot on C6J7 based on instructions from this thread for C6J6 and C7J8 ? Were there any differences in whole process ?

Do you have problems with battery meter on Windows 8 ? On my C6J7 a maximum charge is 95% and after discharging it stuck on 7% for more than 2 hours and then info about 6% and turn off 1 minute later.

What do you think about this C6J7, any other problems ?
[Teclast X98 Air 3G] ImJamIN:
There is another thing to consider; when you install a game from amazon, Google play, ecc. the apk for install is download in /sdcard and then it will be installed on tablet.

If we make this mount point so little, we can occur in problem to install game, dictionary and other apps that are angry of space.

So, we should find an equilibria solution to work on android without any problem still in the case of link2sd. IMHO

I bought it from OKQI Shenzen, via aliexpress and on the Single´s day sale, like pretty many of us.

I just played through 4 Dead Trigger levels and it worked great, no crashing.

3rd time: Anyone got a link for to fix win8 mirrored screen bug?
[Teclast X98 Air 3G] Hendrickson:
Not the case at all. I brought my Air 3G when they first came out and it has a slower laggy touch screen compared to the Air II and crashed trying to play RR3. But I moved to Windows and it was perfect (Apart from a bit of touch lag) However, I feel I was given a second, review unit, return or refurbished one, I later noticed signs it was opened before I even had it.

Things to look for, the top and bottom halves should fit on very tight. If it's been opened, it will have some edges that creak or squeak when handling it. Look for a mark between the plastic and metal half's to see if it was forced open at some point. (I discovered a small indent)

Since it has plastic clips on the top half that clip into the bottom metal base, if it has been opened these plastic clips will never quite be the same, I know as my Air 3G has been opened maybe twice now and it will need a bit of glue around it (to stop any creaks or squeaks) if I can flash the bios and fix it.

I have a new Air 3G ordered and coming with DHL soon and another ordered for a firend that is coming via NL post. Be interesting to see if they have been opened or have defects. Again it's the Teclast Tablet Lottery! - TTL :D

---------- Post added at 10:08 PM ---------- Previous post was at 10:01 PM ----------

Okay this is a common fault now, its about the 5th time we have seen this. My C6J6 has this issue on Windows 8.1 on the stock Windows bios, never got to try the dual boot bios as I bricked it. Have you tired another bios to see if it will fix the issue? It must be a bios fault?

Run HWinfo and have a look at your battery capacity it should read around 34000-36000 if it is reading 14,000 or something like that then Windows is only seeing one battery cell and your battery meter is 50% off :(
[Teclast X98 Air 3G] robusto:
I just ran 3dmark ice storm Extreme, score 7413 and average fps 35.9. Didn´t crash. Is it possible that I don´t have a faulty tablet?

Hendrickson, what was your solution to the mirrored touch problem after installing orientation drivers?
[Teclast X98 Air 3G] muzetas:
Did you try 3.0 open gl test from google play?

If you can, please try it for 15 min.
[Teclast X98 Air 3G] Hendrickson:
Hours of messing with the touchsetting.gt file in Windows/inf

Try different combo's of the remove the file, stock touchsetting.gt file, file with 0 0 0, the file with 1 1 0 settings etc etc. A lot of trial and error (And almost going insane) I had huge issues with this where others the fix worked fine for them. But not me :(
[Teclast X98 Air 3G] heikkiap:
When discharging, it will stay in 7% for couple of hours in normal use, when recharging

It will stay in 95% for couple of hours again, but will finally show 100%.

So, don't stop recharging when it first reaches 95%.

---------- Post added at 11:44 PM ---------- Previous post was at 11:26 PM ----------

As Hendricson told, it is not easy.

Depending on the version and maybe also on BIOS, you have to try combinations of available HD Graphics drivers, touchsetting.gt and orientation combinations in .reg file.

Kaccel....exe seem to be the same in every "download".

I have posted my working settings for C6J6, Win10 with Windows only BIOS (post #787).

I made a trip to dualboot bios, but because of battery meter problems, I came back to win BIOS.

Strange was that I was not able to get touch or screen orientation working with the same settings that I had before.

[offtopic] I still cannot get battery meter working as it worked before dualboot trial. [/offtopic]

For touch and screen I uninstalled and reinstalled drivers and settings for hours yesterday, and finally I got them working. I saved the driver set-up (all drivers from driver backup) that worked for me now. I can't be sure ( based on my experiences yesterday) , that I could reproduce the driver installatiosn again, so that screen and touch works, if I uninstall them now.

I still have camera upside down, but I can live with that.

So, I can't tell anyone, that using my setting you will get them working, you have to try combinations yourself. If you are lucky, the settings and fixes given in the first page works for your device. For me they don't work.

Good luck!

After flashing from windows to android , after restart is shows bios and not possible to go to android . What to do in this situation ?
[Teclast X98 Air 3G] majkel_94:
It's emulated, symlink like links to apps in Link2SD but just for whole partition.

If you don't belive make a quick test - put your SDCard in, make a few photos/movies, they unplug your sdcard and open the gallery. You should still can see your photos.

They are stored in internal storage in virtual partition "/storage/emulated/0" or "/storage/emulated/legacy" which redirect apps and OS to /data partition.
[Teclast X98 Air 3G] G3n3R4L:
i need an sd card first to try .....
[Teclast X98 Air 3G] majkel_94:
No need for SD Card, you can take a photo and see that is storage in internal memory - virtual sd card. In your 4GB /data partition.

Tomorrow I will look for how to redirect '/storage/emulated/' to real external sdcard to be able to reduce /data to 2GB :P

I havent tried any other than c6j7 stock bios.

Did anybody has a difference in battery meter behaviour after changing from stock bios to dual bios ?
[Teclast X98 Air 3G] Hendrickson:
That is basically the reading I got give or take 300mWH . There is something wrong with the battery meter, did this happen after flashing the bios? I'm not sure its related as my battery when I first had it reported around 36000mWH. After about 2 weeks of use it suddenly showed 14000.

So maybe its not the bios that triggers it but something else? I was charging and using a OTG hub at the same time which could have something to do with this. I hope there is a fix for this one, as its really annoying. I have seen it mentioned on the Teclast forum to, but no fix it seems. I'll try and fix the thread again.

First - I have never saw that information about my device is too hot ;) in android.

You can run for instance rar benchmark and check that after ~ 10 min still test shows around 1600 KB/s ( speed compression ) if drops - that indicates over hitting - on my tablets even after 10 min still shows more than 1600 KB/s .

I was playing on windows Fallout 3 today everything high just resolution 800x600 and works great 30 - 60 fps.

Ubuntu, Windows, Android Triple Boot

Would it be possible to add Ubuntu to the dual boot through Grub2 or EasyBCD? What should I install first Ubuntu or Windows or Android?

Ubuntu would have to use the same 64bit uefi as android so I'm assuming you would install Ubuntu after android but before windows leaving enough room for windows and using the instructions in the origanal ubuntu thread http://bbs.teclast.com/thread-255275-1-1.html

Then when the dual boot is loaded it will go into grub2 for android and windows for windows.
