hardware

guys, i believe that most of teclast air 3g devices has different hardware, because i have a friend here we bought the same tablet in the same day and they even arrived together, but he has some different driver changes in his device manager, and even with some normal procedures he has it different, and from the comments here i think we should be more careful about that, and try to make sure first if all the teclast air 3g are the same or different hardware .....

edit: for who has any problems with installing drivers or fixes, this is a link win 8.1 pro included all the drivers and foxes and even recovery partition from the teclast forum, i think this will be the best solution, it is updated to 20 november, camera works the right direction, recovery partition is there "it is important btw" only chinese language to change and i think its easy .... i will try to download from pan.baidu and try to upload the image somewhere else so everyone can use it.

Help please

Hi everyone. First thing I want to thanks you all for the time and the help you are offering to us. I am a new user but I'm following this thread and in general this site from long time.

And now my question:

Background:

I have purchased a Teclast x98 Air 3G HKC2 with only android. I unfortunaly wanted to install windows on it. I followed the guide "WINDOWS 8.1 => ANDROID PROCEDURE (thanks to Frontier)" in the first page by petruccig But i'm stuck with the message "Press ESC in x seconds to skip startup.nsh, any other key to continue". After five seconds I get "Shell>"

What I've done:

-I have prepared both the USB Sticks with success

-Installed with success Intel Manufactoring Tools

-Installed with success ADB

-Flashed Android 111

-Flashed BIOS "BIOS_X98_Air_3G_android_to_windows.7z" (the one you find in the guide) with no root permission and receveid "FPT Operation Passed"

-Restart the x98 and got the error message.

What i've tried:

-I've tried to connect a usb keyboard but i cannot type anithing. CTRL+ALT+DEL don't work, ESC don't work and when i get the Shell> screen, i cannot type anithing. It seems the tablet cannot see the keyboard.

-I've tried to connect only the WINPE stick but nothing happens. My usb's pendrive LED won't turn on, it seems the usb is disabled

Please HELP ME I'm very sad right now . I hope I didn't anything that can't be reversed. Many thanks to anyone that will take the time to read and to help me. Really thanks.

Sorry for my bad english, it's not my mother's tongue language.
[Teclast X98 Air 3G] azzy12:
Help!

I have the C9J8 with 1.03 BIOS, I flashed the 1.05 BIOS in windows and it was successful.

I rebooted the tablet and now it's bricked (won't turn on at all, nothing on the screen), is there anything I can do ?

I found this video:

https://www.youtube.com/watch?v=841pMJC_QOk

but there is no guide to using the programmer.

Please help!!
[Teclast X98 Air 3G] KYU15:
Thank you, sir. It works. Need to do that for FB messengers as well.
[Teclast X98 Air 3G] :
Guys, I don't know if anyone cares, but I'm pretty impressed about this.

I thought I'd be completely retarded for even trying, but I thought I'd try playing League of Legends on the Teclast X98 Air II (non 3G) HG8N.

It actually ran VERY acceptable at lowest settings and 1280x960, capped at 30 fps with v-sync disabled. It had a pretty stable 30 fps, though it would sometimes drop to ~20 in teamfights, depending on location and amount of minions.

At the same resolution but higher settings (all mid, except shadows on low) it still ran at 30 fps, but it was much more likely to randomly drop.

If I max'ed out the resolution and kept the lowest settings, it would still run, but at about 15 fps. Didn't even try further than that.

It didn't even get particularly hot after a 30 minute game, which was even more impressive, but that might've had something to do with the fact that I wasn't charging it while playing. Which brings me that the battery dropped 20% after that one game, which is quite a lot.

I'd guess the performance would be better if I had been charging it while playing, but I don't have a powered OTG-hub.

No, I wouldn't recommend anyone actually playing it, as it was awkward on that small screen (though it visually looked fine), but it's totally do-able if one would want to. Just thought I'd share it.
[Teclast X98 Air 3G] mangetron:
Dayems, looks like the flash might have screwed up the Windows portion. Still unsure if there's any link.

Anyone has the links to the teclast Bing iso? The link on the first post doesn't work.

If I installed Windows 8.1 pro, the key would not activate right?
[Teclast X98 Air 3G] azzy12:
Translation would be nice please

"-Connect The clip to the programmer through the handkerchief in komplekle with a clip, as shown in the program (lower left corner, after the chip select): where the figure point in the corner of the chip is the first leg. Campaign have to be careful here. It is necessary to correctly insert the card in the adapter programmer (foot-board adapter №1 should be in place with fine legs in the figure in the prog) and the right to impose a fee on the trail of clips (clips in a line one extreme pink wire and I'm stuck so that it was from the on-board unit-adapter)"

Unfortunately that does not make too much sense...
[Teclast X98 Air 3G] ImJamIN:
If you look at first page should be a complete guide by Hendrickson
[Teclast X98 Air 3G] azzy12:
I did but it's a bit confusing.

I just ordered the kit to do the flash, maybe it'll make more sense when I have them in hand.

4 weeks shipping though :( Just bought the tablet too *sigh*
[Teclast X98 Air 3G] ayyyyylmao:
I've followed this direction for my Air II, and attempted to install the CHINESE LITE 4.4.4 ROM

After the installation, the tablet got stuck on the updating screen. So I rebooted the tab. Now it is stuck in the booting animation. Do you have any idea how to get out of this state? Btw please eli5 because I don't know anything about android.

Edit: When I connect to PC, the internal storage is perfectly accessible. Still, it is stuck on the animation. + when I hold + volume + - volume + power, it just says "Waiting for fastboot command"
[Teclast X98 Air 3G] sandroj:
Did you root the tab before flashing? If not you may need to flash whole android part using Teclast original firmware for your model.

If tab is rooted, from Fastboot go to recovery and wipe data & cache. Unfortunately this will erase all data on android. If you have any important data use Aroma File Manager before doing this.
[Teclast X98 Air 3G] ayyyyylmao:
I can't get to fastboot. That's the thing. When I press both volume buttons and power button, it just says "waiting for fastboot command". When I command "fastboot erase userdata" it just fails.
[Teclast X98 Air 3G] sandroj:
I faced the same problem. You have to boot Windows 8.1 with driver signing disabled. Search on net how to do that, then go to Device Manager, right click Intel ADB Device (which has yellow exclamatory mark), click update driver and when the warning appears click Continue Anyway.

---------- Post added at 07:20 AM ---------- Previous post was at 07:13 AM ----------

Did you use Intel flash tools before following my procedure? And did you root the tablet?
[Teclast X98 Air 3G] ayyyyylmao:
I ended up fixing the problem. Thanks for help.
[Teclast X98 Air 3G] ayyyyylmao:
Another problem: Has anyone found the solution for the 720p only? On youtube I'm only able to play up to 720p. Being unable to play 1440p videos on youtube makes the high quality screen pretty useless.
[Teclast X98 Air 3G] SuperRockmen:
Hi guys, I just got my teclastx98 64gb and was playing around with it for a while. Noted that the battery drain while sleeping seems to be very bad! It lost like 60 percent over 12 hours. Is there a fix for for it? I tried to enable hibernation mode but it just does not comes out as an option under "power". Would appreciate it if anyone could help to solve this issue.;) thanks and appreciate it!

Oh ya what are the things that I must do once I get this tablet? (like applying of patches and stuff or uninstalling of things)

wifi problem

Hey guys,

I find wifi on my teclast x98 a bit slow (slower than on my other devices). Could installing new drivers help? How could i do that? Or maybe theres another way to fix this?

regarding charging

Hey again,

I've got a problem (or I think it is) - was playing with my new tablet till it said there's 4% battery left. I connected it to the charger and kept browsing, later noticed that it went to 2% battery charge (not up, although I was charging. It eventually went dead. I left it for half an hour to charge and can't turn it on now (won't do nothing).. Does it need more charging or there's another problem?
[Teclast X98 Air 3G] ImJamIN:
Try another YouTube app, like ogyoutube that you can find here on xda

There are much thing that you can try. In the first page you can find dome partial solution because 60% it's too much.

You can try to install a new and update version of windows (bing or pro) to find a better battery drain, but remember to make backup of your driver with double driver backup

---------- Post added at 07:34 AM ---------- Previous post was at 07:31 AM ----------

Try to turn off with power button (push it for 12sec) then recharge it with a good 2/2.1 A power supply for at least 2/3 hours.

I hope that this can help you
[Teclast X98 Air 3G] skompa:
Hi, use a 2,1A charger and/or check your charger/cable. 500mA chargers are not sufficient to charge and use the tab. Also Win in sleep eats the battery...
[Teclast X98 Air 3G] ImJamIN:
You can find an up to date driver in the first page and you can try to change your channel to 10 or 11. (On your access point)
[Teclast X98 Air 3G] Mommy87:
Please someone can help me? Many thanks
[Teclast X98 Air 3G] meestic:
This actually worked, thank you. But there's another problem now.. When I turned it on, it showed that it was ~70% charged, and after using it (while charging) for 2-3 minutes ir blacked out again - had to hold power button another 12 secs to turn it off and then on again. When I turned it on, it showed charge of 42% - so it showed wrong battery charge? Btw, it blacked out after another 2 mins, so now I left it alone to charge. Am I not supposed to use this tablet while charging?

---------- Post added at 09:21 AM ---------- Previous post was at 08:42 AM ----------

BTW mine is a HG7N model - Teclast X98 AIR one (no 3G) and I will probably just use Win8 (win10 when I can)

looking for a teclast w8.1 bing iso

Hi folks,

I'm looking for an iso file from teclast for my x98 air ii.

I would very appreciate if somebody could post a link. The link of the first page is dead

And... By the way, how can I make a backup of my bios?

Hello fellow tablet owners.

I have a slight problem with my x98 air 3g (C8J6 according to the backside).

I cant get any of the root programs to work, they all say that debug mode is disabled, which it isnt....im not a wizard, but i know how to check the box next to USB debug in dev.options. :)

Any ideas?

EDIT: yes ive googled/read the posts here/etc .. tried all versions of the different root programs in the first post. ;)
[Teclast X98 Air 3G] rudivb:
It's probably the 7% issue.

When you get to 7% you can still use it for hours before it drops another percent.

You can try fully drain the tablet(with critical battery warning off) and fully charge it without turning the tablet on.

It didn't work for me, but others noticed improvement.

Another general tip for everyone, go to regedit and change the value of CSEnabled to 0

Like this:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Power\CSEnabled to 0

It adds a bunch of options to the advanced power settings.

For example I couldn't just let the screen go off without going into sleep.

But when I listen to music or downloading, I didn't want to go into sleep mode, because it turns everything off.

Now I can configure it to only turn the screen off after few minutes which is great.

Hibernation is also available now!
[Teclast X98 Air 3G] azzy12:
mine did the same, I think the tablet overheats when it's charging and being used at the same time.

Check your event log it should say thermal shutdown under system log
[Teclast X98 Air 3G] SuperRockmen:
Oh wow it works! And ya the option to enable hibernate after a certain time certainly rocks! What is the optimum settings go get the most juice out of your x98? thanks!

Oh no... now it seems that whenever I press the power button it goes to hibernate immediately! Is there anyway to set the power button to sleep only?

I don't know why Microsoft makes this so difficult, they should just make all options available in the power settings.:confused:

It obviously works fine on Windows 8.1, but my parents, who share this tablet with me, uses android, which is much simple and easier to use. So I was wondering if I can watch videos in high definition in Android too.
[Teclast X98 Air 3G] benbraun322:
Oh I'm not sure if you can on android.

Right now android is built for mobiles and 720p seems like the top they can reach on android.

Unless you get an app to raise the quality.

Hello, dear community! I have a problem on my teclast x98 air 3G 64gb c8j16.

[Teclast X98 Air 3G] raaav:
I just got my C9J8 Tablet and thanks to all these great guides here I managed to install mirek190 rom v3.1 and a Windows 10.

Here's something to help others, too:

After installing Windows 10, you have to install all these drivers from the driver package manually and remove all drive letters of the android partitions.

I've created a little script, to make it easier.

Put it in a file called "install.bat" in the directory containing all driver subfolders and run it. For me it is "Air 3g drivers\Air 3g drivers\teclast x98 air 3g win drivers\Drivers\install.bat". You still have to accept the installation of each driver, but all that remains is one click. Do not reboot, until everything is finished.

It might also be a good Idea to remove the igdlh.inf_x86_88aa2f5adfcb3fba driver from that directory and install it manually after everything else finished.

After installing all drivers, the script will also remove all driveletters from D to Q

@echo off
for /f "tokens=*" %%G in ('dir /b /s /A-D *.inf') do %SystemRoot%\System32\InfDefaultInstall.exe "%%G"
for %%G IN (d,e,f,g,h,i,j,k,l,m,n,o,p,q) DO mountvol %%G: /d

You can also access the windows partition from Android, if you have root. I only managed to access it through terminal, but that's enough to copy some files:

Run the terminal emulator and type this to create a mountpoint at /sdcard/win and mount the partition

su
mkdir /sdcard/win
ntfs-3g /dev/block/mmcblk0p17 /sdcard/win

Now you can work with the mounted partition:

cd /sdcard/win
ls
[Teclast X98 Air 3G] :
Yup, it was there. I didn't do anything special, except I ran it from my USB-stick, meaning I installed it on another computer first. But I've seen another guy (maybe Hendrickson? can't remember) have the same issue.
[Teclast X98 Air 3G] kirches:
But why? The battary is 8000 mAh about, i think it's enough.
[Teclast X98 Air 3G] benbraun322:
I did the same.

You installed it on another PC and then copied the Riot Games folder over?

Strange that I dint have a mouse and you do.

From my BlackBerry Z30 or Teclast X98 Air 3G
[Teclast X98 Air 3G] :
Yes, that's exactly what I did.

I just recalled (lol get it?) that I never actually installed DirectX. I just downloaded d3dx9_39.dll and put it in the root of the game folder. I did the same thing with one other missing .dll. I didn't think it'd work, but it did. I don't know if that'd make any difference, though.

Have you tried running it in windowed and borderless?
[Teclast X98 Air 3G] benbraun322:
Lol yeah I did the same also I googled the name of the dll file it said I was missing and installed it. But I only had one missing dll not two.

I have not tried it in windowed and borderless yet.

You think that could make a difference?

From my BlackBerry Z30 or Teclast X98 Air 3G
[Teclast X98 Air 3G] :
I think I had two missing dll's for whatever reason. I don't think that matters, though. I could also just remember wrong.

Yes, it's possible it could make a difference.

Also try deleting your config file, just for the sake of trying it. It'll generate a new one next time you launch the game.

If that doesn't work, then I'm out of ideas.

Update Intel drivers always to last version.

Download Intel Drivers Update Utility:

In windows mode:

http://www.intel.com/p/en_US/support/detect

Install it on tablet, open it, auto detect, download and install. Reboot.

With the last version of drivers (graphics) installed you get rid of lag when right mouse botton is pressed ;)

Have you proved your tablet connected to tv by HDMI in windows 8.1 mode?. I´ve tried with differents tvs and cables, but didnt get it. Even tried updating drivers and nothing. Of course i used projects to a secondary screen option, expand screen, duplicate, i tried everything....

In android mode there is no problem, can connects to tv.
[Teclast X98 Air 3G] mangetron:
thought i'll give an update of the situation. managed to re-install win 8.1 after testing 3 separate images found on web. so far this one is the most reliable of all:

magnet:?xt=urn:btih:cc9748e655915fbe107ca6196cebda51d544a108&dn=Windows+8.1+with+Bing+-+AKA+CoreConnected+x86

torrent magnet link.

activation works fine.

only thing is the front camera driver is not updated. so that will require some searching if you intend to reinstall your Windows OS.

some tips:

1. make a restore point in windows after installing all the drivers

2. make a usb recovery usb in the event you need to recover your system.

this will be useful if you update windows and something screws it up. I've had that issue when I was installing two other images of Win8.1 with bing and installing updates. it will boot you to the repair menu after restart.

hope that helps and trims down the time of your reinstall.

I'm not positive on the method of installing only Windows. But you can install the dual boot BIOS and when you go to install Windows just erase all of the android partitions and install Windows over them this will basically give you the same result and ensure you get 60 Hz screen refresh rate.

Many thanks for the reply. But my situation is a bit differente. I can't access Android or windows. USB Host seems disabled. I cannot change my BIOS.

You are right, I'm not sure if it is the android ROM or the tablet itself, but I cannot use streaming apps on my C8J7 either.

I don't know if your model is the same or compatible with ours but in this thread we have x98 air 3g with these code : c6j6, c6j7, c8j7, c8j6, c9j7, c9j8, c9j6, etc.... So your hkc2 seem little different and probably the bios too
