I guess together we can do something lol

i did order pci to lpt port but sadly my topmax pro programmer still not like it, i guess i have to wait for the usb programmer ....

we are on same boat :) lol

Okay thanks, Is there anything I need to know when flashing it? And If I can't flash it, how will I know is it just not detected by the flashing software and worse case scenario is it easy enough to unsolder and remove?

Thanks for answer , did you have such file X98 Air 3G (C8J7)-Android4.4.4-V2.00-1CF3.rar , because from the teclast it downloading in horrible speed. And on xda I see only modified android .
[Teclast X98 Air 3G] SUMMERBREEZE:
I will find a better link for you, wait for me, also you need internet download manager to download with fastest speed.
[Teclast X98 Air 3G] jacfry:
This flashrom software won't program the chip if it's not detected. If it will find the Winbond chip then you are ok. It will also verify the contents of the chip after programmig. you can find links to the web pages I used to do it in my previous posts in this thread. It's really easy once you open the case. I just had to try different USB settings to find the right USB port under linux. I'm not an expert in linux.

I havent done anything or with windows yet, so you better ask these to someone who knows better than me :)

But if you want a 1 usb stick method, download windows 8.1 iso vl pro version 32 bit and also RUFUS.. and a 4gb usb stick.

Make a bootable FAT32 USB stick with RUFUS.. Google it abt how to do it. Leave the installing driver stuff after win installation. At least, I would do this way

and observe how much temperature on CPU you have - I want to know how much retain heat CPU.

Mine after 20 min has ~ 41 C - and no freezes
[Teclast X98 Air 3G] kodoq:
which one is a btter option

hi everyone

i'm thinking about buying the teclast x98 air 3g but with some issues around it ( like freeze, etc.), is it better to buy the teclast x98 air 2 (non 3g version)? is there any differences between these two tablets except the 3G option?

thanks a lot
[Teclast X98 Air 3G] SUMMERBREEZE:
Thank you, i will try them and let you know. RAR test is the most intensive and torturing one for CPU?

What about this one?

https://play.google.com/store/apps/details?id=com.into.stability

By the way, i am doing some antutu benchmarks wiyh Intel Turbo Mode ON and OFF and also GFX Ram MINIMUM and MAXIMUM and do some screenshots, i will also share them
[Teclast X98 Air 3G] muzetas:
I checked my on this benchmark and after 3min cputemp shown 62C and I stoped the test. The throttling messange is appering at 60C on my device.
[Teclast X98 Air 3G] SUMMERBREEZE:
thanks for the feedback, ill also try soon

---------- Post added at 12:38 AM ---------- Previous post was at 12:09 AM ----------

I ran the test for 20 mins. Max temp i have seen was 61 Celcius, i didnt see any thermal throttling popup aswel

My tablet also works at 44-46 c at system idle.. cpu usage is %2-3 at 498mhz speed, this is very interesting.. [MENTION=2198172]mirek190[/MENTION] has got this degree after 20 min cpu throttling test and it my default cpu temp :rolleyes:
[Teclast X98 Air 3G] mirek190:
I that case we almost sure that some of that tablets have not properly installed cooling system.

Mine after 3 min had 30 C

Need just more results.

In that case repairing such thing will be very easy :D

---------- Post added at 01:41 AM ---------- Previous post was at 01:39 AM ----------

But you was very close ;)

But you see mine after 20 min or even more I had just around 40 - this very big difference.
[Teclast X98 Air 3G] SUMMERBREEZE:
yes i just wrote about this above as RED.. very interesting :silly:

I will also try another popular stabilty app

https://play.google.com/store/apps/details?id=com.into.stability

It stress both cpu and gpu..
[Teclast X98 Air 3G] mirek190:
And probably on dual bios the voltage is a bit bigger and probably your cpu was even faster over hitted - that's why still was unstable .

Mine who was unstable still has low temperature and is stable as rock now.
[Teclast X98 Air 3G] SUMMERBREEZE:
Antutu tests are ready.

Intel Turbo Mode OFF

DVMT Pre-Allocated 32M

DVMT Total Gfx Mem 256MB

Aperture Size 256MB

Screenshot = 1

Games never crash

Intel Turbo Mode ON

DVMT Pre-Allocated 32M

DVMT Total Gfx Mem 256MB

Aperture Size 256MB

Screenshot = 2

Games crash

Intel Turbo Mode OFF

DVMT Pre-Allocated 512M

DVMT Total Gfx Mem MAX

Aperture Size 512MB

Screenshot = 3

Games never crash

Intel Turbo Mode ON

DVMT Pre-Allocated 512M

DVMT Total Gfx Mem MAX

Aperture Size 512MB

Screenshot = 3

Games crash

CONCLUSION :

Turning the Turbo mode on or off, doesnt effect GPU's performance very much. But as you can see, the benchmark scores related with CPU get lower when TURBO MODE OFF..

So if our games go fine and dont crash when the turbo mode off and the gpu scores are still fine, we can say that OUR PROBLEMS are related with CPU/Voltage and thermal throttling-not enough cooling problem around this.

[Teclast X98 Air 3G] robusto:
Hi, did some testing. I played Real racing 3 for 25 minutes, got a throttling msg once in a while. Then the game crashed, so I started dead trigger.

Played it for an 25 mins, got some brightness/thermal msges, but the game didnt crash. Quitted the game, started 3dmark Ice storm Extreme, score 7409 and average fps 35.

RR seems to be buggy with x86 hardware, it force closes now when try to launch it. 3dmark didnt output any errors. Games plus 3dmark ran fluently without signs of throttling.

Do the throttling signals tell that I have a faulty gpu/soc?

Mirek which bios version (dual or not) and which x98 version do you have?
[Teclast X98 Air 3G] severall:
My after looping benchmarking hit 70C. Back of the tablet is not hot. Just a little warn. No freeze at all. Maximum allowable temperature of this processor is about 100C.

These problem which people have maybe caused by overheating..but not a CPU. Maybe RAM or some kind of voltage regulator.

Its a shame not having a custom recovery... i miss too much...
[Teclast X98 Air 3G] WSOFT2002:
Seems here have some people may have the same problem as my X98 Air 3g (C6J6), I try to tell my story more detail.

I get my X98 on 6 Oct, I am very happy with it in the first two weeks (well, It does reboot for a few times), Everything normal, including playing games (like Candy Crash ) for two to three hours with no problem.

I install Asphalt 8 on the third week (I have try other 3D games too), when I playing A8, I have 90% hang in the first round, the best I can is about two round, then I thought it may be the bad implementation of Android, so I flash the X98 to Windows and install A8, but get the same result. At that time I don't think it is an overhead problem because the machine is cooler then I play these mini games, until one day I was in a car and have the air conditioner blow to the back of the X98, that was the first time I can play A8 nearly an hour without hang (Under Android).

After that, I did a few test and confirm if there is a cooling, my machine can remain longer under 3D games.

Because I am living in Hong Kong, so I can take my X98 to Teclast Service Center in China. When I told the tech. at service center my problem, he said that it's because these games is not for X86 (I didn't notices A8 have X86 libs at that time) and may hang and refuse to repair the unit. I show him the video from LVL91 in #135 (Thanks! LVL91) and run the benchmark in front of him and it hangs, after that he agree to repair my machine.

I wait for three weeks, and get the machine back at 3 Dec. I am lucky this time, my X98 don't hang in 3D games anymore. the longest test I made is, after the first round in A8 and left the X98 replay for two hours with no problem (With charger plug in)

PS: They don't mention what they had done with my X98.

Here my suggestion,

1. Return or get repair if you can, it is a hardware issue!!

2. Try cooling test, if this helps then the adding Thermal-Adhesive may work.

3. If the cooling test fail, the last option is flash the old BIOS and disable the GPU Tubro, and this will reduce performance 30~40%

[Teclast X98 Air 3G] Maringer:
Big problemo. Almost certainly easy to solve, but I need advice as to how to do the fix.

Fundamentally, I had my Android-only tablet set up almost fully (using the 'lite' 4.4.4 ROM), but have now got myself into a bootloop after trying to install the Microphone gain fix.

After copying the XML file across to the tablet, I thought I had selected the correct file permissions using Rootbrowser but I'm now encountering bootloops so there is obviously a problem somewhere.

Earlier in this thread, one or two posters have mentioned it is easy to fix permissions using ADB, but I can't seem to access the tablet in any ADB mode but 'sideload' through the recovery so can't access adb shell to try and change permissions.

Though reasonably computer-savvy, I've rarely used ADB so I'm pretty much a novice here.

Can somebody give me a reasonably basic walkthrough as to how I should get into ADB mode so I can access the ADB shell? I'm using a Windows 7 x64 installation and I think all my drivers are correctly installed as I was able to install the new ROM in the first place. The tablet appears in the device manager but isn't visible by ADB in any way but sideload.

If only we had a CWM so I could just "fix permissions"!

Any assistance gratefully accepted as I'd rather not go to the trouble of having to reinstall from scratch if at all possible!

Then when the dual boot is loaded it will go into grub2 for android and windows for windows.

Has someone been able to run Ubuntu or some other distro ?

Any instructions (not in chinese) ?

Where do you have seen that max temperature for z3736f is 100°c?

I have read much articles but no one report this specification. And no one write voltage core.

While if you look at 3735 or 3770 or any other bay trail processor, these specifications (Max T. and voltage) are write.

That's strange.

Well, i just make a assumption based on similar cpu. I'm quite sure that 70-80C is completly safe temprature for this CPU. Modern Intel processors made in 22 nm architecture start to throttle after hitting 100C.

Once i had a laptop with Core i7 4702MQ . During gaming, CPU temperature was 95-98C, completly stable.

[Teclast X98 Air 3G] 25gee:
ok, so I don't have the tablets just yet (and mine will be an air II sorry) just a few questions sorry if I sound stupid.

So just to clarify, Intel Manufacturing Tools, these are used to flash the bin file which preps the systems bootloader for the OS being used right? so for android it installed fastboot and for windows I imagine some other means of booting from the USB etc? these are NOT the actual roms at all but are for preparation of installing said OS (a little clarification here would be nice as to what exactly it flashes and its main use in single and dual boot situations).

Rom installation - does anybody know if the processes are the same for 3g and the Air II? and would the roms for the Air 3g run on an Air II or should I look specifically for the Air II roms as there doesn't seem to be much info on the Air II atm (though similar hardware no?)

We have to get it into DnX mode as stated and then push the rom over with the flash.xml via the Intel tool?

the Intel Manufacturing Tool as managers and go to the menu File -> Open. There, choose the folder of ROM (X98-Air-2), find the file "flash.xml" and open it.

- We keep the tablet down the VOL +, VOL- and POWER in order to display the logo of running Teclast DnX, connect the USB cable and Intel Manufacturing Tool begins the process of flashing Android ROM. Wait until the process is complete, disconnect the tablet from the USB and disable the device.

In which the windows install would also be done as highlighted in the tutorial but with the Air2 bios?

What exactly are the 2 bin files for in the fptw? what do they contain/flash? what is the tool for? just want a nutshell of what each tool is responsible for, which does bios and which does the rom install?

Android bin and windows bin? what exactly are they needed for?

Does the tutorial highlighted in the thread work in the same way for the Air II? does anybody know? just scared I'll go doing something stupid and bricking the thing :confused:

My C8J7

Hello everyone!

IYesterday I received my Teclastx98 3g.

It's coming with:

Adroid 4.4.4

IFWI 5.6.5 (no ideea what is this)

BAsedband version H350_V3H.20.06 (idem) :)

Kernel version 3.10.2

Build number V2.0020141106

For me, this numbers and versions or an alien spaceship are the same.

The problem is that the tablet like you all comented have not Google Play.

I was speaking with the provider and told me that Teclast will solve this issus in about 3 weeks (I don't really believe them but let's say they will).

I had tried to root my tablet following indication in this forum and the tool given, but when in console i choose "E" nothing happen.

So, at this point, after loosing all night and most of today in searching options to solve the root and google play problem I'm totally stuck.

Beside of this, When I use my camera to record video, is blocking the tablet and restarting itself.

I guess I bought a wrong tablet.

Anybody can help me with this problems, please. I know is a pain in the neck to help a dumb but maybe somebody may have mercy:(

Greetings!

I had the same issue with Google Play and i knew there was a fix in this thread (please check the first page)

I have sorted the problem but The things you must do(change the language of your tablet into English) :

1) Go to Settings / Developer Options / USB Debugging and CHECK the BOX(Turn it on)

2)Verify apps over USB - Uncheck (Turn it off)

3 Uninstall all drivers from your PC/Laptop (connect your tablet and better do it from DEVICE MANAGER/Always check the box and delete the drivers aswell, not only uninstall)

4) Restart your PC and download Intel Manufacturing Tools from THIS LINK

5) Install them in this order in the QUOTE BELOW :

6) Now when you connect your tablet to PC, PC must be seeing your tablet. Now Download The Tool BOX by Frontier from THIS LINK and UNZIP IT.

7) RIGHT CLICK on ROOT_me!.bat and RUN IT by Admin rights and DO the ROOT Procedure. When it is done, it will want to restart and let it restart the tablet. Thats it, your tablet ROOTED. After that, you can continue with Google Play Fix which already written in first page/android development. Hope it helpes

I was about to purchase this Teclast x98 Air 3G tablet from Aliexpress for 230 USD.

But I see that devs are fond of C6J6 model and all development is based on that.

After purchase I shall be relying on this thread for updates/tweaks/fixes other than the official channel.

So what are these models

C6J6 / C8J7/ C9J7

Any other model ?

Does it refer to Android OS/Windows OS /Dual OS models ? If so, then which is what ?

One seller told that C8J7 is the Android OS only model. Can someone please confirm ?
