Well. this units has more secret than we suspected ;)

On my C6J6 texdroid didn't caused Bootloop, Nomone messed up with my keyboards :/

Anyway if these kind of software caused bootloop or stucked on TPad logo you don't need to reflash, just fix build.prop permissions using ADB. And always make copy of files that you're going to change.

Oh. We need CWM recovery :)

When i'm in home i'll try change DPI by editing build.prop. I don't like installing apps when it's not necessary.
[Teclast X98 Air 3G] SUMMERBREEZE:
You are perfectly right, we need CWM! :) Thanks for the ADB info too, but what about the commands for pushing the build.prop ?
[Teclast X98 Air 3G] BoORDeL:
It should be "adb remount" and "adb push <local> <remote>"

If u want to change permissions just use adb shell (if in need adb root first to have a root adb) and use chmod

Please correct me if i am wrong.

This is an how to for ADB http://www.droidforums.net/threads/how-to-use-adb-all-commands-and-options.6865/

yes but system needs to be writeable. not READ ONLY.. and by ADB, it is not always easy to give this access to SYSTEM folder.
[Teclast X98 Air 3G] severall:
adb remount

adb push build.prop /system - build.prop must be in the folder where ADB is. If not, you have to type folder path

Changing permission:

adb shell

su

chmod 644 /system/build.prop

I guess my tablet is died. Help please

Hello. Im writing my first post in xda. I have a problem I hope you can give me a solution. thanks in advance.

I had converted my tablet ( teclast x98 air ii) to windows. Then i didn't like windows on it and tried converting it back to android . I followed the guidance in first page and couldn't do it. With manufacturing tools I can't go into droid boot mode. each time "entering dnx mode" screen comes. when i connect the tablet on entering dnx mode to pc while in manufacturing tools flash is ready, I get this error: "ERROR : Port 0/1/4 #0: IFW flash failed - SN : Baytrail61502261" I disabled all boot priorities from windows bios but it also didn't work. I guess if I go into droid boot mode, it will be done but anyhow i can't enter to droid boot mode. :(
[Teclast X98 Air 3G] BoORDeL:
HAve u tried to reinstall USB DRIVERS?

Have u tried to flash ur device from another pc?
[Teclast X98 Air 3G] selimdek:
Thanks for your fast reply. I tried it from another pc. But all the same. I can convert it to neither android nor windows. When i tried to reinstall windows with bootable usb it fails and says "your pc ran into a problem and needs to restart"
[Teclast X98 Air 3G] SUMMERBREEZE:
now i tried something, you know, when we turn INTEL TURBO MODE off, tablet doesnt hangs in games yes? and we have heat issue at high cpu speed. But i left the TURBO MODE ON and experienced this as below ;

I downloaded this app:

https://play.google.com/store/apps/details?id=com.dsht.kerneltweaker

I did some changes in settings,

CPU Parameters : MAX 1.66 GHZ

KERNEL : I/O SCHEDULER - CFQ (CLICK CIRCLE)

READ AHEAD SIZE : 256 (CLICK CIRCLE)

and i ran the UNITY OpenGL ES3.0 benchmark, it didnt hang at all, tried 10-15 times but all was fine!

But when i set it the next speed , 1.743 ghz, the benchmark test failed! Later gone back to 1.66ghz and benchmark passed all tests again!

So what do you think? It is also a kind of voltage issue alongside with thermal throttling?
[Teclast X98 Air 3G] pcbroute:

im sorry, but i didnt receive yet the programer so i cant made video or tutorial, and my eetools topmax, still no working du to lack of lpt port ..

but ist simple to use it guess ...

install the programer

connect the end of the clip to the programmer (pin 1 to pin one)

and on the other side of the clip you should see red wire .. pin one i guess

connect to the chip (you will see a small dot on the chip tell you where is pin one)

then clic auto-detect, try to see if the clip connect all leg and the programmer should find the chip

then open the bios u want to fash and flash it ..

what you problem ?

So, could anyone explain or summarize the difference in flashing Dual Bios (Android & windows) on Air 3G and Air II?

Any "Notepad ++" editing difference should be taken care of?

Any Rom flashing procedure should differently be done?

I know all of us here are experimenting the device we own, but I just want to make sure the difference on Air II model.

One suggestion, could anyone mark the date of updated info on Front Page if any thing is added in future?

It seems all info is growing and being updated as many participate in this flashing job.

My Air II is finally on the way home any minute. I am so exited. Hopefully share some experience with you all. :)

I really appreciate you
[Teclast X98 Air 3G] igius12:
thanks for answering

I flashed my x98 air 3g c6j6 with toolbox bios whitch was wrong (it was for x98 air)

now my tablet doesn't power at all and cant be recognized by the pc (win 7) I installed all drivers and tools

tried all buttons but its dad.

I think 99 % must be bios wrong flashing. ineed procedure to flash with those external tools cause I don't want to burn any circuit.

Enter BIOS by pressing "ESC" key during boot and under the "Save and Exit" menu, scroll down to the "Boot Override" option, find the USB drive and select it to boot from it. The BIOS will boot into the USB Drive and Windows install should start.

[Teclast X98 Air 3G] supercowz:
Nice app ! :)

Was looking for something similar !! Well done ?
[Teclast X98 Air 3G] majkel_94:
Looks like max voltage in BIOS is too low and the CPU can't work and you get freeze ;)

There is strong relation with frequency, voltage and temp - all this things have an influcence for stability.

Sometimes when you cool down the tablet it will won't hang but sometimes the voltage is still to low to work ok.

Also when the temp is low you are in Turbo mode all the time so you might observe the voltage issue.

The batches of Intel CPUs always has quite random parameters. In desktop CPU one unit work with 1.15V out of the box and the second with 1.25V :P

IMO the problem is that the Teclast didn't tought about it and we have constant voltage in all units.

Someone has better unit of CPU and he don't have freezes while the second person not. That's it :D
[Teclast X98 Air 3G] HDtracer:
Haha you are correct on both counts. I forgot that the toolbox installs supersu instead of the Chinese super user.
[Teclast X98 Air 3G] SUMMERBREEZE:
i agree every sentence you write mate!

Even we make the temp very low (like [MENTION=4777359]acc007[/MENTION] did) tablet will freeze sometimes when the cpu/voltage is not stable. CPUs need a proper and right voltage to work at max speeds (here it is 2.16ghz) if bios is set up properly for this, even you succeed overal temp to cool down, it wont be stable.. Wish somebody could look at the kernel and do some tweaks for us.. maybe one day
[Teclast X98 Air 3G] PWMx:

[Teclast X98 Air 3G] acc007:
I start to believe this is exactly the same. After my thermal fix I never crossed 51 deg C (with OpenGL 3.0 benchmarks), and my tablet still freezes sometimes...
[Teclast X98 Air 3G] Cozla:
I lowered CPU frequency to 1660 Mhz. Tablet become more stable. I have been played RR3 about 20 min and it didn't freeze, also I did about 30 test by OpenGL but tablet finely froze (with normal CPU freq usualy it froze at 6-8 test). Temp wasn't higher than 60 °C. It is geting better, but not perfect. I belive that freezing have something common whit CPU voltage about you wrote before and solution of this problem will be found soon.
[Teclast X98 Air 3G] jcespi2005:
Sounds like should be posible to raise or down the voltaje until found a stable value for every CPU, am i right?
[Teclast X98 Air 3G] acc007:
yes, that's standard procedure when overclocking or underclocking, but in PCs this is set in BIOS. Here we have no such option in bios unfortunately :(
[Teclast X98 Air 3G] ImJamIN:
But you are on old bios, right?
[Teclast X98 Air 3G] acc007:
No, I flashed dualbios. And a few minutes ago I installed Win8.1 as well, so setting it up :)

i am happy the trick i wrote somehow helped. Yes i also noticed that at 1.66 ghz, tablet more stable, much more responsive and faster than max 2.16 ghz.. some of them may wonder how it is possible? the answer propably is under voltage problem.. tablet can still work with intel turbo mode and max cpu freq is 2.16 ghz right? but cpu is not totaly stable. if you have experiences with overclocking before, you will get me. with low voltage but high cpu speed, benchmarks give worse scores and freezes happening.. i think this is the same issue here.. when we lower the cpu speed to 1.66 ghz or for someone else can be even higher or even lower, tablet works more stable cos cpu is stable :) the voltage is just enough for that freq at 1.66ghz or around..

Wish we had some android kernel tweakers here.. they would play with kernel and do some voltage settings and some other performance tricks. and we would see if it sort the problems or not..
[Teclast X98 Air 3G] SUMMERBREEZE:
please do the settings exactly as shown in attachements below and try the benchmark test once more and tell us what you experience

I found a problem with downloading Windows image from Baidu through the link.

Baidu asks an account to download but i don't understand Chinese at all.

Probably, SUPERCOWS version would be an option. My question is: If I install SUPERCOWS version of Windows, do I have to use SUPERCOWS android rom as well?

OMG, the SUPERCOWS on MEGA also requires the DECRYPTION CODE.

Does anyone have alternative link for WINDOWS?

I am in the middle of installing....got stuck here.

Both links below don't allow me to download...

"Whatever the case, make sure your USB Drive is formatted as FAT32! Very important!

I used this wimboot image that automatically uses WinPE to get through the whole install process automatically without needing a single mouse click, which also has all the drivers and everything installed and working properly:

I figured out Baidu one (since I was stuck in flashing widows) with my Chinese friend's help (opening a Baidu account for downloading).

The disappointing thing is to download from Baidu will take 12 hours. (incredible....)

If anyone wants to flash the Dual Bios, buy a cup of coffee for Supercow and download from MEGA before starting anything.

P.S. By the way, will your version of windows only work with SUPERCOW android rom? Anyway, :good: thank you so much for the effort to develop roms and upload them to MEGA. I should have bought a cup of coffee for you before I started. Let's have a raincheck.

"Dead links" on Mega

Link is not dead, forum software shortens the URL (you see three dots ...). In original posts the link is correct, but the "name of the link" is shortened. If you quote the post, the target of the link gets screwed and is with these three dots (as it only copies the name of the link, obviously).

If you try to go to shortened URL (= name of the link), MEGA tells you that the file is encrypted ( actually there is no file with that name).

This is my experience. I might be wrong.

This is the link's name as forum software shortens it (with extra space to prevent it appear as a link here )

I've solved that problem. You have to uninstall all of the drivers and install them once again. After installing ADB driver I've connected tablet in DnX mode (buttons VOL UP, DOWN, POWER at the same time) - tablet was recognized and proper driver was installed. After that flashing with Intel Manufacturing Flash Tool was successful :)

[Teclast X98 Air 3G] kinhvanhoa:
DUAL BIOS INSTRUCTION missing features.

I am on AIR II MODEL, to be clear.

1. If you follow the dual bios instruction, you will encounter CHINESE instructions on screen until you've done everything successfully. It might be depending on ROMS. I didn't use SUPERCOW's ROMS due to the link problem.

On Windows, if you are not Chinese speakers, you will be panicking until you download the language pack for the default language.

On Adroid, the situation is same but it's a lot easier.

2. For the final step of the Window installation, you may need a bluetooth mouse for REMOVING RAW PARTITIONS.

Hand touch will not work. You need physical "left button."

3. On Android, the Market app will not work, which mean you cannot sync your account from the market.

I followed Frontier's suggestion., but it doesn't work since it requires the "ROOT ACCESS."

I've asked here whether I should "ROOT" the device or not. No body answered. I think you MUST ROOT your device for applying possible solutions.

4. After the installation, your device will be "downgraded (if you're on AIR II)" to C6J6 weirdly.

Some expert should port the stock rom of AIR II for better and stable performance.

These problems are I've found so far....

BTW, is it ok to root after the DUAL BIOS installation is done? LINK2SD definitely requires SUPERUSER GRANT which my device cannot grant.

It's been tough...though... without the market app on android is simply no good.

(anyhow, it looks good with dual bios although some features are not working at the moment.)
[Teclast X98 Air 3G] SUMMERBREEZE:
mate maybe use some camera apps from google play (google camera, camera360, camera zoom fx etc)
[Teclast X98 Air 3G] jcespi2005:
Of course you need root to apply the Link2SD solution for Play Store ;) apply root after installing Android in the Dual System... or at any other moment, is no dependent...

For me the only issue is camera upside down on Win 8.1 (no teclast Wni 8 used), but don't care...
[Teclast X98 Air 3G] kinhvanhoa:
