strange.....

root@x98air_hg6m:/ # would suggest it is logged in as root?

If you do "adb shell" to your device then type "su" does it load into "root@x98air_hg6m:/ #" ? if it does you should be logged in as root, if this works it would point towards having some form of root access to the system at least from there we can try to set the /system/ folder to read/write (although the root user should be able to do this anyway?)

Try typing "adb root" and then typing "adb shell id" and seeing what it reports back? should say "0/root" somewhere or similar

I did notice that when I tried to SU through ADB the tablet loaded up an alert asking to grant permissions (this was after rooting though of course) did you have anything like this pop up during this process? have you tried other rooting methods previously?

You are running the script as administrator I presume?

If all else fails, perhaps someone else with a bit more know how can assist? but if you can get into the root user it should literally be the "Root" user as in full permissions to chmod folders and push files to the core system.
[Teclast X98 Air 3G] adyjob:
Thanks for the reply. I haven try any other root method yet. I even fully reset the tablet before follow your step. If i do "adb shell" an error : more than one device emulator.
[Teclast X98 Air 3G] 25gee:
Can you type in "adb devices" to see what comes up, there should only be one device (the Air II) do you have any other phones/devices plugged in?

Another thread on here suggests that another program is running on your PC which emulates the ADB, one example mentioned is "BlueStacks" or something similar? close down all programs which are unused on your system in the task manager and any phone sync software etc, unplug anything you don't need and basically try to get windows running as bare as possible (Assuming you're on windows) (if you know how you can also check services to see if there are any services running related to mobile/android? android studio springs to mind)

did the "adb root" return the same error?
[Teclast X98 Air 3G] adyjob:
Once you mention the "bluestacks" then i realize that i have a "bluestacks" which is running at the back end. After close the bluestack all the problem solve. Now my tablet is root. Thank you so much for the information. You really help me a lot.
[Teclast X98 Air 3G] 25gee:
Excellent, glad I could help!

Thankfully the folks here at XDA-dev have come up with these problems before and found a fix :) props to them.
[Teclast X98 Air 3G] adyjob:
Anyway, if i wish to remove most of the chinese bloatware, any software you would recommend? I mean a safe way without leaving any problem to the system.
[Teclast X98 Air 3G] 25gee:
I have not removed everything myself yet, but many of them can be removed by dragging the icon up to "uninstall" those which cannot I have simply gone into the information for and disabled, reason being I am not yet sure which apps may have core components required by the system and have been too busy playing with the tablet (only having it 2 days haha :D ) but will have a go through it, most root file managers/program managers/backup apps like titanium backup should be able to remove them though I'd imagine.
[Teclast X98 Air 3G] adyjob:
Since my tablet had rooted and the playstore is working fine. Should i remain the Link2Sd apps in the tablet?
[Teclast X98 Air 3G] 25gee:
I have kept it as it doesn't hurt to have it and can come in useful for other things, I have noticed it taking SU permissions every time the play store checks for updates so it may be required to allow the play store to run properly, though I have not yet had a look to check so don't quote me on that :)

Only thing you can do is test it, remove it and if play store stops working then you know hehe.... can always re-install playstore + Link2Sd ;)

I just followed the dual bios tuto on the Air 3G thread, the 3G and Air II bios are the same ( for android and dual bios )
[Teclast X98 Air 3G] mrbun9l3:
I have used C6J7 for 6 days and I have never had any hang. The only problem is battery meter. Quick discharge to from 95 to 7% and then few hours on this level.
[Teclast X98 Air 3G] adyjob:
My tablet Teclast X98 Air II with Android 4.4.4 after trying with few games, i realize some 3D games while playing will hang. I have to power it off (long press power button). so far i have try Real Racing 3, Beach Buggy Blitz, Frontline Commando 2. all these 3 games will cause my tablet hang... anyone have idea to solve this issue? I have try Subway surfer, Temple Run 2 both working fine.
[Teclast X98 Air 3G] 25gee:
The 2 tablets we have here don't hang, they do mention throttling due to thermal events which is not really good... but they never hang.

You can always rip them open and add a bit of heat sinking :) really easy to get apart.

Not sure why yours is hanging though :(
[Teclast X98 Air 3G] adyjob:
i don't think is heating problem, all the heavy 3d games i test when the games just started to play for few seconds the tablet will just hang.:mad::mad::mad:
[Teclast X98 Air 3G] 25gee:
Could you try the CPU-Temperature app from play store and run these games with the overlay enabled to see what the temperature is?

I'm curious as we have had one of ours as high as 68C and it still never hangs, so would like to know if it is consistent with a specific temp range or something else?

Edit:

Sorry didn't see the previous post, but if you can get any other info at all to try and pinpoint the issue it would be nice to try and find the reason behind it.

What bios do you have? standard? anything different?

Which things cause it to hang? I'd like to try them on ours and get a CPU temp from you at the point of hanging as we have had the CPU jump from 40's to 60+ in a few minutes :confused:

Just trying to see if the games that do work on your system are at an equal or lower temperature than the ones that do not work as this will for sure eliminate heating (unless the app mis-reads)
[Teclast X98 Air 3G] adyjob:
I will run few test to get back to you. Just now i did try with the game Subway Surfer which i previously stated it works without hang. but it seems like not that way. I did install cpu temperature and put it overlay. My tablet at first at temp ~50C. When i run the games around 6 minutes the cpu reach 68c and then later it hang. I thing you are right i do have heating problem. for the game like Beach Buggy once i start the game the cpu jump from 50c to 60c. I don't even play the game, in few more second the cpu temp reach 64c and then the tablet hang. Again i test the Real Racing 3, the cpu temp start frm 50C, as the game load and play the demo ( i never play the game), the cpu temp started to increase until 66C and then it hang.
[Teclast X98 Air 3G] 25gee:
Wow!!

It took me a good 45 mins to an hour to hit 65+ but then I am in the UK and the ambient temperature right now is not amazingly hot, still that is fast.

Which ones crash/heat up the quickest? I'll give them a go on our tablets and see what happens.

If you take apart the tablet (be careful of course, but it does come apart fairly easy) you will see a brown thermal pad on the SoC and RAM in the tablet, on mine the pad was not sitting flush against these and was lifted slightly.

You may want to look into ways of shifting the heat away from the SoC though as that thing gets hot fast :(
[Teclast X98 Air 3G] adyjob:
Real Racing 3 is the so far the fastest. Before game started 50C and during loading and start play demo. the cpu temp jump to 60, 61, 62, 63... 66 and hang. Just took around 30 second.
[Teclast X98 Air 3G] 25gee:
Even before taking apart my tablet it took a good 30-40 minutes to even get near that hot in RR3, that is insane!

You might want to whip the thing open at some point if you feel confident enough and take a looky, ask a few on the air 3g thread about what they have tried as they seem to be having similar issues.
[Teclast X98 Air 3G] adyjob:
You look so familiar with the problem, did you have before the same problem? I can see that you did take apart your tablet before. I think i will contact the seller first to discuss this problem cause i just got it 2 days ago. I still have purchase protection. But back to your suggestion, what you want me to do after open apart the tablet?
[Teclast X98 Air 3G] 25gee:
Well I'm only aware of the issue from the air 3g thread on this site, many people are having issues with heat on these and they are almost identical hardware wise.

There is a brown heat transfer pad above the SoC on the inside of the tablet which can be loose sometimes, it is basically a thin sheet of metal with a sticky black pad on it (not really great)

There are many pics of it over at the air 3g thread and also in that link I sent you for the toolkit to root, there is a folder on there for pics.

Heat issues

I bought the Teclast X98 Air II (HG6M). I already solve the (ridiculous) google play bug, but the tablet hangs up everytime i try to play a 3d game (i tried shadowgun, GTA Vice City, Wild Blood). 30 seconds after the lauch of one of these games, the tablet freezes.

Curiously, NFS Most Wanted runs fine!

I think that´s a temperature isssue. My tablet reaches 60-65 celsius degrees running games. That´s maybe a software fault, since a lot of users had similar isssues. Will teclast roll out a update?? I hope so!!
[Teclast X98 Air 3G] adyjob:
Before i purchase this tablet i already known the playstore issue but not the heating issue. The seller at Aliexpress also admit problem on playstore but the seller told me there will be a update release around 3 weeks from Teclast. I hope the release will also solve the heating issue. Playstore issue is easy to solve as i known there is a solution in xda but if i had known the heating issue i would not buy this model. Anyone who plan to buy this X98 Air 3G / Air II , i would not recommend as i dig deeper into xda, actually lot of people facing the same problem.
[Teclast X98 Air 3G] 25gee:
Mine sat about 40-45 when idle and hit 63-68 when in games it never ever froze though.

I wonder why some are heating so badly and others are fine? the same applies for the 3g version, some are crashing all the time, others are having very few issues at all.

If you are OK with ripping them apart (which is very simple on these) you can easily add a heatsink to the SoC and check/replace/reseat the existing thermal padding (which isn't that great) ours now radiate the heat through the back casing through a small modification, sure it gets a little warmer to touch but not uncomfortable and it never goes above 55-60C even heavy duty for hours.
[Teclast X98 Air 3G] adyjob:
My idle CPU temp is at 48-50 and that i consider quite high. As i play games the temp will quickly hit 60 within few second, when it hit 64 and 65 the tablet will froze. I was thinking maybe the kernel is also contribute to the heating problem as it control the CPU, GPU and voltage of the tablet. I will try to install kernel tweaker to downclock the cpu and see any help.
[Teclast X98 Air 3G] tirmey:
I don't know if it's really a heat problem, because shadowGun freezes at 61 degrees, but shadowRun reaches 63/64 Celsius degrees, but runs fine (tested today, 30 mins of gameplay)...

Anyway, that high temperatures certainly drops out our batteries.

Hey guys, I decided to flash back to Android 4.4.4 due to preference. I rooted it using the toolbox. Fixed the Google Playstore issue with the link provided in this thread. Installed Titanium Backup to remove the unwanted apps and installed the Lollipop Google Now launcher through the Playstore to replace the terrible laggy chinese skin. I'm really enjoying the tablet now that i'm back on Android. I have a HG5N.

I take no credit for any of the instructions and simply providing information that the wonderful users of XDA have supplied.

Camera upsidedown

Hi, I just got a Teclast X98 Air II, Android version updated automatically to 4.4.4. It came whith the Google Play Store issue, which was solved efficiently with the help lines in this thread. I wonder if anyone has a solution for the upside down camera. I only have this problem with the rear camera, not the frontal one.

I tried several apps for camera, but no one I found has the possibility to invert the image. Of course, these problems are strange and can only happen in chinese tablets, I suppose....

Any help will be appreciated.

By the way, what are the main reasons everyone is trying to convert the tablet to Windows 8.1 ??? What is really better with Windows in a tablet?

[Teclast X98 Air 3G] zeronavigation:
I received my Teclast X98 Air II yesterday (HG6M) with Android 4.4.4 installed. It worked alright although missed the PlayStore. I wanted to install Windows 8.1 on it to give that a try. Unfortunately something went wrong: i succesfully rooted and flashed the BIOS according to the cmd. But after the reboot nothing is working. As in: screen stays entirely black, no sounds, inserted USB-stick doesn't light up.

So it looks like it's bricked, although it seems weird that the screen doesn't respond to and inserted energy cable.

I already ordered the two products to reflash the BIOS, as in the post of Hendrickson. But can anyone confirm it's bricked?

Whenever I get these items I'll try to fabricate a more detailed tutorial (although my skills as an electrical engineer are low).
[Teclast X98 Air 3G] kinhvanhoa:
I have the same problem with the DUAL BIOS system. Probably, I have to go back to the stock Android ROM.
[Teclast X98 Air 3G] Xpedience:
Odd thing about these tablets, I have 2 Firmware versions so far, and 2 different OS levels.

So before I can do anything at all with them I need to find a good, stable ROM without all the bloat. Been looking everywhere, looks like SCROWS is the only real option for non-Chinese?

Perhaps Cyanogen will play with the Teclast soon.
[Teclast X98 Air 3G] Miles Wolf:
Hi everybody!

I'm thinking on buying the Air II, but after reading a bit here and in other places I have a lot of doubts that I would like to know if you can solve them:

1- I am interested only in Windows, I don't want to use Android. The heating and hanging problems are there in Windows too?

2- I would buy ths tablet only with Android installed because it is cheaper. Is there any problem to install Windows if it only has Android?

3- Is it possible to fully delete the Android partition?

4- Any known issues with Windows on this tablet PC?

5- Is this the tutorial found here (http://xdaforums.com/showpost.php?p=56788730&postcount=20) still the one that I should follow to install Windows? Any thing you would add to this tutorial because any issue discovered later?

6- Any important thing to tell to a future buyer of this tablet? Cautions, advise...

7- Would you recommend any other tablet instead of this one? I know there's the Air 3G, and I would like its 3G connectivity, but as far as I know the Air II has some better specs (60Hz screen instead of the 48 Hz of the Air 3G, for example).

Thank you.
[Teclast X98 Air 3G] kinhvanhoa:
Windows is working as I tried the Dual Bios but I am not sure the Camera upside down problem will last or not on a single bios system.

Is there any expert who can figure out X98 AIR II's camera problem? I think it is the key issue for any rom other than the stock rom which I didn't even try as I initially installed the Dual Bios. :(

OK. I'll keep it for a moment since I am still interested in the Dual Bios installation.

By the way, is there any difference between the Windows 8.1 (the Chinese one I found on XDA) and the Windows 8.1 with Bing (PRO version?)? I am actually not familiar with Windows 8.1 so just curious.
[Teclast X98 Air 3G] kracz:
I install Chinese win 8.1 with Bing next only change key to pro and download language pack. Unfortunately, I have not enough posts and I can not give you a link to the outside regarding differences. :crying: Windows 8.1 with Bing costs $0 for computer manufacturers to include on their laptops and tablets.

[Teclast X98 Air 3G] kinhvanhoa:
I understand but I am already on Windows PRO 8.1 without Bing. I don't think we need to chose the version with Bing over the simple Chinese version of Windows 8.1 though. Am I missing some points here?

---------- Post added at 02:25 PM ---------- Previous post was at 02:20 PM ----------

This instruction fixed the screen upside down on Windows from the start-up (although it occasionally generates an error message about loading some drivers... If I wait for a minute, before touching the screen it doesn't show any error message).

However, the CAMERA issue never goes away..... I don't know where this problem came from the beginning.

Strange.... Hangouts on Android and Skype on Windows... I cannot use both of them..

I think I should install OSes once again from the Dual Bios.
[Teclast X98 Air 3G] kracz:
I changed nothing (I did everything according to the instructions). I do not have any problems and bugs. All works. How to think so the only problem with the installation of a clean version of the system is the appropriate drivers.

Nah that's not true, you're able to get 60hz by default on Air II with Windows preinstalled, and also as far as I know all the 3G versions from TinyDeal with also Windows preinstalled comes with the 60hz enabled (no dual boot).

Question about partitions and installing Windows 8.1 Pro

X98 Air II with Android 4.4.4 to Windows 8.1 Pro.

When installing Windows 8.1 Pro and it gets to the selection of drive/partition in the installer do I wipe all partitions and let installer continue just as a normal install on a new PC or do I leave partition structure alone and select the largest free partition.?

I am just going to have single-boot Windows 8.1 Pro on this tablet and no android and wanted most available space.

Is there any drawbacks to removing all the partitions that were already there.
