[Teclast X98 Air 3G] G3n3R4L:
sad news, teclast air 3g is being sold on aliexpress officially installed windows 8.1 with all drivers and everything working perfect ... check it out here

http://www.aliexpress.com/store/pro...Quad-Core-Tablet-PC-2/609719_32222560720.html
[Teclast X98 Air 3G] Hendrickson:
Bit over priced $230, still I'm glad I was able to flash Windows 8.1 to my Air 3G. I'll see what the Air II is like, even if it's missing 3G and GPS.
[Teclast X98 Air 3G] G3n3R4L:
the point is, mixing the gps 3g driver with camera what cause the inverting of the camera ... so if u will remove the 3g gps, everything will work more than fine
[Teclast X98 Air 3G] SUMMERBREEZE:
you are a crazy man, what will you do with two tablets that have almost same specs? :)

---------- Post added at 10:45 PM ---------- Previous post was at 10:38 PM ----------

but the one you sent on the link also have 3g and gps, and im sure its camera isnt problematic..

if we somehow find the driver or dump it for the device on the link, we could install it in our teclast x98 air 3g
[Teclast X98 Air 3G] G3n3R4L:
This is my seller, i sent him a msg asking for the firmware or drivers ...? I hope he will pay me attention, but in fact he is the best seller for trclast so maybe no

And most important, teclast already have the firmwate for their device with all the drivers, and dual ooot, but they are not gonna give up on them now till they make some money first by making new customers, old customers already bought but the way to make new customers is to give them something special

Im only waiting everyday for something new official from the teclast engineers not someusers on the forum of teclast,

And btw this xda, this forum should be full of developers, which they can develop drivers, but till now i see only some people waiting for help depending on the chinese users "including me" ....
[Teclast X98 Air 3G] SUMMERBREEZE:
you are right, there should be more people and pay attention to this tablet. its a great device for how much it cost, but..

but im sure the stable windows will be leaked very soon and then things will be much better :good:
[Teclast X98 Air 3G] Hendrickson:
I have my Air 3G, the Air II I have ordered for someone. So I'm only going to have one.

[Teclast X98 Air 3G] tumich91:
I'm waiting for new version with anotcher proccesor who will have fixed drivers for fresh rate 60Hz + ofc 3G + GPS.
[Teclast X98 Air 3G] SUMMERBREEZE:
so you mean this is the windows image (in CHINESE LANGUAGE) that Teclast X98 Air 3G Win uses at the link below (C6J7):

http://www.aliexpress.com/store/pro...Quad-Core-Tablet-PC-2/609719_32222560720.html

and you will try it in our X98 Air 3G (Android) version (C6J6)

hope i didnt understand wrong?

if it is as i say so, then we are waiting for the good news :good:
[Teclast X98 Air 3G] HDtracer:
Hi everyone,

So after a few days on 4.4.4 for some people, whats the verdict? Update from v1.10or not bother at the moment?

I have spent ages getting the tablet to a good looking and functioning device (gravitybox, viper, Nova etc etc) and dont really want to go through it all again if the update doesn't do much/fix much or breaks just stuff haha.
[Teclast X98 Air 3G] SUMMERBREEZE:
are you happy with your tablet on android? after everything you have done, is it much faster and smoother?

thanks :good:
[Teclast X98 Air 3G] HDtracer:
Yea its pretty good. Dont know if its faster as it is a pretty speedy tablet anyway.

The screen scrolling on my LG G2 is smoother in some apps than the X98.

Nova and Apex launchers are definitely smoother to use, xposed and gravitybox help with the look and lots of tweaks.

Really need viper4android to tune the speakers and headphones, its like Teclast just turned the gain on the preamp up way too high to fix the original problem of too low sound.

Just have the odd forced reboot on some apps like youtube etc, usually after they they have updated..........strange.

Just wondering what peoples thoughts are on the 4.4.4 update, if its a worthwhile one or it just introduces more niggles into the system.
[Teclast X98 Air 3G] scrawl78:
Hi all,

If anyone is interested, I posted a Win 8.1 driver dump from my Air 2 (HG6N).

Can confirm no issues with upside down cameras and LCD runs at 60khz. Not sure how applicable this is to the 3G model but the drivers are there if you want them.

I do have a question - do you notice a slight delay when dragging on the touchscreen in Windows?
[Teclast X98 Air 3G] BoORDeL:
I've used ur camera drivers on my AIR 3G.

Images are still inverted. I think this is a bios implementatíon issue.

Would be nice have a c6j7 bios dump

ANYONE HERE WITH C6J7??
[Teclast X98 Air 3G] BoORDeL:
Windows 8.1 32 bit NOVEMBER CUMULATIVE UPDATE PACK : http://www.microsoft.com/en-us/download/details.aspx?id=44985
[Teclast X98 Air 3G] ambrosio5:
Yes that's exactly what I mean. I don't think there is any other difference except of course the Bios version, that's the only missing part of the puzzle. Hopefully someone will buy the C6J7 version and we'll get the Bios dump before teclast decides to publish it. .I did not try it tonight because it was very late. I'll keep you posted when I'll do it.

GPS

Does the GPS on this tablet work both in Android and Windows? Or just in one of them? From what I read the phone option only works in Android.
[Teclast X98 Air 3G] ImJamIN:
GPS works in both
[Teclast X98 Air 3G] TomaszD84:
I used the leaked Windows with Bing image and my tablet activated automatically using the OEM key from the dualboot BIOS. If your tablet came with Windows preinstalled and you didn't flash the BIOS, it will work automatically.

If you wish to flash your BIOS, BEFORE YOU DO, make sure you dump your OEM key to clear text using this http://www.datafilehost.com/d/aeef6e2a and keep it somewhere safe, I would also recommend using the Teclast Taipower BIOS utility to inject your key from the existing BIOS to your new BIOS image file. Only then flash the new BIOS.
[Teclast X98 Air 3G] Originalas:
There are many ways, but Windows 9 Product Key Viewer app (pkeyuibx_v1.4.9) probably the easiest.
[Teclast X98 Air 3G] HDtracer:
Some apps that put an overlay on the screen cause supersu to not detect button presses. You can disable the feature in supersu settings. I had the same problem with Lux brightness app.

---------- Post added at 09:29 AM ---------- Previous post was at 09:16 AM ----------

Yes let us know how it goes.

Bit confused by their advert, says Air 3g in the title and then picture says only fits X98 3g which has the bigger frame size.
[Teclast X98 Air 3G] darklife96:
Help me Please T_T

Hi, i bought the Teclast X98 Air 3g from aliexpress with the dualboot when it was on promotion, now it is arrive, but both the system are unusable since they are almost entirely in Chinese :(

Now , I wanted to make a cleaner installation of both systems (Android and Windows 8.1 custom rom pro), but reading the thread I was shocked by how many things there are to do and I'm very confused..

I hope someone can clear my head of how it should proceed, my version of the tablet is the c9j8 and just in this version is explained little or nothing :(

i'm sorry for my bad English, but I'm Italian xD

many thanks to all especially to those who will give me a hand
[Teclast X98 Air 3G] Mouratti:

Format(erase) Windows Only?

Hi;

How format(erase) Windows Only without erasing the others partition(Android-Cache....).?
[Teclast X98 Air 3G] TC93:
I don't know about Android, but for Windows you should be able to change it to your language. This video here shows how, only its on a different tablet but I would think its the same.

https://www.youtube.com/watch?v=v4gbBAcgmpQ
[Teclast X98 Air 3G] perkinna:
I have not found a way to do this yet. It would be very, very, very useful.
[Teclast X98 Air 3G] thehobit:
It may be possible, if you disable quick boot, you will always have the logo of AMI (bios maker) when booting.

Once you tap on the logo, you will see a very small on screen keyboard. If your eyes are sharp enough and fingers are small enough, you may tap "del" and get into the bios.

---------- Post added at 10:16 AM ---------- Previous post was at 10:12 AM ----------

Are you trying to reinstall windows or just delete the partition and get more space for android?

In the first case, you can delete and format the partition during the installation phase, just do it very carefully. the biggest one is windows.

---------- Post added at 10:21 AM ---------- Previous post was at 10:16 AM ----------

Thanks, done.

For some reasons it applies for portrait mode but not for landscape.

I use an up for the rotation, should that be the case with this ROM?
[Teclast X98 Air 3G] mtr33:
Just to be clear: you did use the X19-57135 image (SHA1:63422a198729941f47e7f3563197b1f3ac8c5640) or another one?

Thanks, that's the one I meant (typo 57134 vs 57135 :p).
[Teclast X98 Air 3G] perkinna:
I have done this however it does still leave a lot of Chinese scattered throughout, particular at the login screen for example if you want to shut down without logging into a user (shutdown, reboot and I assume the third is sleep are all in Chinese characters still). I also tried to create a new user and I had to give up it was too hard.

Would be nice to be able to set the language to English for all fields.
[Teclast X98 Air 3G] forcedv:
My C9J8 dual boot 3G arrived and to be honest I was not expecting such an awesome device (biggest surprise for me was the 3G sim works for both systems).

Everything I've tried works (again a big surprise) so I'm not going to mess with it too much, but I'd like to remove the Chinese apps from Android but need to know which ones are safe to remove?

WARNING - install any other launcher and make it default one, before deleting tUI
[Teclast X98 Air 3G] perkinna:
recommended USB hub

Can anyone recommend a decent quality USB hub that works well with the X98 air 3g? I have determined that my current generic (cheap) hubs are not going to work properly.
[Teclast X98 Air 3G] forcedv:
Thanks Rudnik8.

Now I'd like to find a case that also acts as a keyboard which works with both operating systems.

But ideally, it's the use of a mouse that makes Windows more useable and I just can't find a mouse that's

intergrated in a case or one that can be stored within a case?

Having just one tablet that is Android, Windows and a 3G phone is amazing and I'd like to keep that minimal look with a keyboard and mouse.

Any recommendations?
[Teclast X98 Air 3G] DuneNormal:
Dear experts--first off, thanks to all those who did all this amazing work.

I have a few quick questions, I read through the posts but did not seem to find the answers

1. Is it possible to use the whole screen? There is a nav bar at the bottom. I installed Nova but the stock buttons are still there, even after removing all the apps.

2. I bought this to send text messages, but my T-Mobile sim (USA) doesn't work, even after the seller assured me that the device had GSM 850. Is the GSM spec completely and seriously wrong? No way to unlock it? And if so, is there any US sim that will work?

3. Absolutely cannot flash a custom rom Mirek 190 (using Intel Flash app), I have rooted, tried USB debugging, set the numbers of the version, etc, etc, it stops 15 percent through and says WFIW error. Should I try another rom? Worried about bricking....

The Android version is 4.4

4. Screen changes brightness when playing video--anyway to change this?

Thanks.

Hi, where i can find this image?
[Teclast X98 Air 3G] scrawl78:
I can personally vouch for this one. Four port hub which can charge the tablet at the same time.

Note this won't solve the problem of some portable hard drives not working with the tablet due to drawing too much current. Only a powered USB hub will solve that.
[Teclast X98 Air 3G] HDtracer:
Hi, which model tablet do you have?

1- You can if you use xposed and gravitybox. You can set when the and how the navigation bar appears and disappears

2- A fair few pages back someone else was having problems with T-mobile 3g/calling etc. Not sure if there was ever a solution.

3- More often than not a fail at 15% is a bad driver install or possibly the wrong vid and pid numbers etc. The rom is never usually the cause of a flash failing.

4- Havent seen this one

Or if I can to find here, please help what page.

I asked the same question some time before, and nobody answered...

I tried to boot Hiren from usb stick, but couldn't make it, it just skips usb and boots directly Windows. I tried to make usb uefi bootable with few programs (including iso2usb mentioned here), but not one really works.

I have read something that factory dual boot devices are unable to boot usb, but don't know whether this is true or not...

Hi,

I'm looking for a tablet around 10" with windows, and this x98 air 3g seems to be the best in this range of price. I've red a lot of this long thread, but not all the pages for sure! My understanding is that even if i'll plan to use it only with windows, it's better to buy the dual boot one for it's best hardware and then remove android partition. Is it always the best thing to do?

Ubuntu on Teclast X98

Did somebody test install Ubuntu on tablet? I tried test only run Ubuntu from USB as is described here http://techcat.ca/threads/onda-v975...-mint-linux-on-intel-atom-bay-trail-tablet.8/

Is needed reflash BIOS for Ubuntu installation?
[Teclast X98 Air 3G] BrocasHelm:
I managed to make my C8J7 device dual boot, install mirek's rom(great rom btw, just a minor glitch on each reboot with the clock position in the top bar) and I made a usb bootable image from some windows 8.1 pro I had available. I did everything according to Hendrickson's tutorial as shown in Youtube here:

https://www.youtube.com/watch?v=rLjayeQJg4Q

and almost everything went smoothly.

There are two problems though. I have no GPS(I think) and no gravity sensor rotation. You can see in the screenshot below(click for bigger) that two devices have a ? next to them, even after installing the multiple drivers from techtablets, Frontier's repository etc.

If I check the properties on either of them I get the following message in the device status:

This device cannot start. (Code 10)

{Operation Failed}

The requested operation was unsuccessful.

As shown also, the Kionix KXCJ9 Accelerometer SPB driver is properly installed. Just the other Kionix device is not working.

Any ideas on what to do to make things work perfectly? I really like the windows tablet experience so far.

Hi,

I do not own yet this tablet, but based on my research yes, an ipad air 5 case will fit. You just ave to take care of the position of side ports than can require to cut or drill to be accessible with some case.

Here a video sample where you can see an ipad air 5 case used with a teclast x98 air II which is the same size:

you can ask seller for increase windows partition / removing android. In other case, you will receive dual boot tablet with dual boot bios loaded. It's one step less to windows only tablet. Check the prices. Better option is order the smart cover and flash tablet by yourself.

Latest bios??

Hi, i've reistalled windows 8.1 pro and android lite 4.4.4 in my C9J8 so i don't modified the original bios with the tablet comes (dualboot version). Now i think that this bios limit the tablet in windows use, such the speed processor since turbo boost, or grafics, and I noticed slowdowns not so sporadic and annoying troubles with touchI, a excessive battery drain with windows and I think that is the original BIOS to give some of these problems. My IFWI version is 5.6.5 and the tablet is C9J8, what bios i can use to maintain the dualboot and resolving this problems? Thanks :)

I've got a C8J7 and only using Android. Everything is working well, and I'm using mirek190's 3.1 rom. Only problem I have is that xposed framework won't work. When re-booting after installing, soft bootloop happens, and have to disable during boot and uninstall. So I was wondering if anyone else has gotten xposed to work. Also a small request regarding the bottom menu bar; would be nice to have the "options" button added, since some apps needs the fixed options button to get into the menu to access preferences etc.

- advanced settings

- apply language settings to the welcome screen, system accounts, and new user accounts

- change system locale

[Teclast X98 Air 3G] kosrica:
The true fact about this tablet is that it gets quite hot when using Android and I speak now about normal applications, e.g. if you open 2-3 tabs in google chrome which may have some graphics or you are on facebook the tablet gets hot and the termal notification warning appears. You can say that this doesn't represent a problem because you can dismiss this notification event but unfortunatelly you can feel the back of the tablet how hot it gets and eventually I don't think the tablet life will be so longer if it operates under these conditions.
