Hey all, it's still not clear to me how I create a Windows install USB stick so that it will detect and allow me to install with my Teclast OTG cable. I have downloaded the image that Mirek made available in post 2165. I tried using Rufus to make that self-bootable but the Windows icon does not show up when I boot my device (c6j6).. I only see the Android device.

I also downloaded the WinPE_User_20140814.7z and extracted that directly to my Win8 USB stick and that didn't seem to help.

Any idea what I'm doing wrong? Thanks!

Hi mirek190, first thanks for that upload. But i have problem, i installed the dual boot bios and android lite 4.4.4, i downloaded your installation and extracted to my 8gb fat32 usb. when i choose to install win8 on boot i get (windows failed to start boot bcd microsoft\boot\bcd error code: 0xc0000225) as i was reading that is regarding the partitions. i used the partition.tbl 5000M from the previous posts that i found.

[Teclast X98 Air 3G] mirek190:
Do you have dual bios and android 4.4.4 ?

I remember that my 1st teclast freezed on aspart 8 afrer I took out form box to check out is working or not :D but 20 min later I updated bios and andrid to 4.4.4 lite and from that time works without any freezes .
[Teclast X98 Air 3G] SUMMERBREEZE:
nope, i hvent flashed anything yet, just change the launcher and remove some chinese bloatware.

this is the screenshoot

I am using the official rom of Teclast, i didnt flash anything(neither BIOS nor LITE ROM)

because after i got the tablet, i did tests and i found out that GPU is problematic and games freeze, i was thinking to return the tablet and thats why i didnt touch it very much

the roms you uploaded, are they english and drivers added yes?

If yuo have mirrored touth is very easy to repair.

Just replace that fle I mentioned few pages earlier in windows \ int from fix camera archive and restart tablet.
[Teclast X98 Air 3G] keepfishes:
Okay Guys, I have updated my tutorial again I hope it is clearer now: Post #1929

If you already downloaded the Windows Full/Lite ISO, just extract and copy and paste it into your USB drive and you are ready to go! NO NEED FOR RUFUS!

[Teclast X98 Air 3G] mirek190:
In that case you should try update BIOS and ROM.

Maybe in older BIOS is set up to low voltage for GPU as dehaut or something like that.

As I said my first teclast was unstable as well from box but 30 min later I updated everything and now ( from 1 week ) any problems - I play a lot because I like.

I have 3 tablets any each of them is updated bios and ROM - no problems at all.

2 last ones I updated just after unpacked then .
[Teclast X98 Air 3G] keepfishes:
I don't think it is due to the Partition 5000M file. It is due to something else. Try extracting the downloaded image again and then copying it to the USB drive again.

[Teclast X98 Air 3G] davidonabus:
I'm making some progress.

I managed to get windows installed but the display was inverted. I'll look into getting that fixed shortly. The problems that still remain:

- The Win8 lite install results in a Chinese install. Did I miss the instructions on how to get an English install?

- I lost my Android boot. When I start my machine the white OS choose screen now only shows Windows.

Hello guys, i have a small problem. I flashed dual boot bios from existing Windows 8.1 installation. All good, Windows 8.1 working great with 60Hz refresh rate

But want to install Android also.

My problem is that i can't enter DnX mode to flash Android.

After pressing Vol + /- + Power it says " Rom selection switch to Android" It only appers 2 or 3 second so i can't even read this excactly, after that Windows start to booting.

What should i do ?
[Teclast X98 Air 3G] mohamad_skiller:
What is your tablet model ? C6j6 ?

Where do you havebuying can you give me a link?
[Teclast X98 Air 3G] TeutonJon78:
It really does depend on the games. If the game is entirely in Java or a good engine, then it should work in either environment. However, if they used NDK stuff to write low level C, then it might be too optimized to run on x86 without the developer doing extra work.

I think the devs do have to compile for both architectures though, in cases like that, even though they can upload them as on combined APK. I'd have to image most newer stuff doesn't have a problem on either -- Intel has done a lot of work to make that the case.

[Teclast X98 Air 3G] ImJamIN:
Have you update your bios with the last one that have release teclast on its server?

Have you tried to update your rom with lite version?

Maybe that the reason of your crash should be these two things.

Try it and keep us updated.

P.s. try to change dpi too
[Teclast X98 Air 3G] HDtracer:

Can we just change the dpi in the build.prop from 320 to 260 instead of using an app?

I had this issue in the beginning, it seems some Air 3G's have different base touch configs. I had to experiment with this setting and also removing the file completely.

Yes, I edited the build prop in mine before moving to Windows worked fine.

So is it a Soc fault or a rom fault that I could not play Real Racing 3 or Dead Trigger 2 ? RR3 would crash on the download data screen and Dead Trigger 2 gets stuck on the loading screen forever.

[Teclast X98 Air 3G] seba2000:
As I see, there are few problems which you can find in X98 Air 3G:

- problems with software install (dual bios / android / windows) - it seems that this is more users skill issue instead of real problem

- inverted screen (touch), not working play store, etc. - that is also related to users skills (proper patches needs to be done)

- gpu / soc failure (android only? - crashes in some games) - I would say that this is not confirmed - it seems that problems might disappear after bios / android update (I am looking forward for [MENTION=3014815]SUMMERBREEZE[/MENTION] confirmation)

- some different minor problems

I saw that some users complains also on battery drain issue (windows only?). I believe that [MENTION=4723868]keepfishes[/MENTION] complain on 5% / 1 hour leak in standby mode which would be a huge trouble.

Is it a real problem? Could you guys please share with us about your feeling regarding battery? (especially in Windows)
[Teclast X98 Air 3G] keepfishes:
1) Official ROM has lots of bloatware and useless chinese apps.

2) Everything just becomes smoother... Try it yourself, just use Texdroider app.

---------- Post added at 07:58 PM ---------- Previous post was at 07:47 PM ----------

The main problem is some users do not read instructions properly, either that or they don't understand English well. But one problem is true, on some computers it is difficult to use the IMT to flash the tablet due to driver incompatibility...

The GPU problem is there and is real. Some units have faulty SOCs. What I advice is that when you first get your device, TEST, TEST and TEST it again. Use the OpenGL ES3 benchmark, run as many games on it until it gets really hot and see if it crashes. If it doesn't, you have a perfect unit. That's for GPU.

Some folks got touchscreen defects also, go to the developer options under settings, turn on the "show touches" and "pointer location" options and see if the red dots are very far apart or the touch response is jerky. If they are, your touchscreen is defective and you should ask for replacement.

I have asked the question about battery drain here many times, but I received little if any replies on this matter. :( Seems like I am the only one getting it? Before the dual BIOS flash, in connected standby I lose 2% per hour when I monitor via sleepstudy. After dual BIOS, it is now a whopping 5% drop in one hour of connected standby. This is the most pressing issue for me as of now, because I keep having to shut down Windows. Seeing that I get no replies here, I went to the Chinese forum and asked, and apparently the problem exists for many of them as well, well at least I got more replies there than here about this issue...

You can read my thread here

The battery life, when in use in Windows, is I think comparable to the surface pro, or slightly lesser if I'm not wrong... But keep in mind what kind of processor the Surface Pro 3 has, and what processor we have, it's a world of difference.
[Teclast X98 Air 3G] mirek190:
VERY IMPORTANT !!!!

Please add this to firt post !!!!

Yesterday at night is was asked to check RR3 on my tablets because some people have problem with unstable on games especially like RR3 .

I said on my 3 tablets works perfect ! That's true.

I made today some investigation - on my 1st tablet flash old bios !!!

Afret it RR3 was VERY UNSTABLE - freezed 3 times my tablet within 10 min :( on old bios.

Later flashed again dual bios - RR3 works great - no issues at all.

Conclusion :

Probably on old bios i too low voltage i some problem with GPU bios or so.

Aftet updated to dual bios no problems at all.
[Teclast X98 Air 3G] keepfishes:
Good find, I'll try RR3 as well. Previously I tried the OpenGL ES3 on my tablet on old BIOS and it worked fine, it didn't crash even though I repeated it 5 times and the tablet got quite hot. I think the best benchmark now is RR3? HAHAHA :laugh:
[Teclast X98 Air 3G] seba2000:
And this is what I am talking about - if [MENTION=3014815]SUMMERBREEZE[/MENTION] and other users could confirm that GPU/SOC problems still exists after bios and android update then I could assume this issue as confirmed.

For now some guys just complains about crashes, but when they are asked to update bios and android there is no reply from their side...

[MENTION=4723868]keepfishes[/MENTION] - that is true, this is quite strange that nobody (except you unfortunately) complains about battery behaviour in Windows. I am looking forward for some other users opinions.

Could you guys (Windows users) share with us about your feelings regarding battery life? Did you noticed any unexpected leaks in standby mode, short working time, etc.?
[Teclast X98 Air 3G] G3n3R4L:
why no one searching the old posts, we spoke before about it ..... hardware are different between each piece of the tablet that means some people will have issues some are not, for now all the c6j6 having no problem at all with the dual boot bios, the rest are just lucky unlucky, all the problems are coming from the bios, so people who are having problems with the dual boot bios and the bios is unstable with them, they can just flash the old bios if it was stable to them either android bios or windows bios, till we find another dual boot bios and they can flash it freely.......

some questions like power drain, i had a lot of power issues with the old bios and once i flashed the dual boot bios all my power issues are gone, so maybe you need another bios.

someone asked about the dpi, teclast made the rom without changing the dpi of the screen, everything was just bog and large and the rom for me was some old smartphone and moving with slow motion, after changing the dpi the rom is smoother and lighter. fonts and resolution is smaller and suitable with the screen properties.

im sorry guys but really this thread becoming a call center, there is no bug reports anymore. everything explained with details here in this thread but we keep only adding posts ........ we need to look forward for the bugs and solutions. and how to install android on ad card or give it smaller sized partition .....

edit: for the power drain issue change the teclast charging cable to slow one ..... tested, the slow cable charging so slow but will give you 8-9 hours battery life

[Teclast X98 Air 3G] G3n3R4L:
all we know that short big usb cable such as the one we received with the tablet is faster on charging, so i was charging my tablet with some long smaller cable "magro" and the battery used to live for 9 hours for me, since yesterday i stated to use the teclast cable, only 25 mins using the tablet after recharge and the battery is 88%

the probleme with android i think is the rom , change dpi for me not change anithyng better view but little laggy again in scrolling with nova launcher , i have 32k score with antutu but my old optimus g with 24k score is better smooth on nova launcher scrolling very better , in game no problem work well but if you want better framerate and smooth in game , use app for change resolution at 1440x1080 is better for game ,

now on windows 8 touchscreen scrolling is very smooth and game is working perfect but is same probelem as android i never play at 2k resolution because is not maximum framerate of game , i think 2k resolution is just for video not for game it's intel gpu on it not a nvdia gtx or radeon and is not a surface pro 3 with core i7 or i5 remenber it's 180$ tablet
