I had to install drivers manually.
[Teclast X98 Air 3G] Frontier:
Can you elaborate on the particular batch of these X98 Air 3G's?

Are they the same build version (C6J6)?

Any other distinguishable properties (i.e serial number, build date etc)?
[Teclast X98 Air 3G] Hendrickson:
I recorded some gaming on the tablet as requested. No resets here either. I did run Asphalt 8 at the native res for a long time and its smooth, but can stutter. It was around 20-25 fps? Much faster than my Onda v975w was. It was really stuttery. Here in this video I tired Asphalt at 1366 x 768 and its super smooth.

And here in this video I ran Civ 5, Half Life 2 Lost coast and Asphalt 8 at 2048 x 1536.

I do think I got a good CPU in this one, no heat issues after a few hours of gaming to really push it and never got over 62 degrees and to the touch was warm. Not hot.

Does Windows 10 need any special new drivers or anything I should be aware of? I'm thinking about flashing it on my X98 to have look at how it runs on the unit.
[Teclast X98 Air 3G] LVL91:
I have no idea about which batches have problems. The info in "About tablet" in settings is the same. And the serial numbers don't make sense to me. I'll need others to provide their serial number. (please PM me, don't put your serial number on this public thread)

I do have a very interesting found on the slow charging problem.

It's very simple. Probably due to the specification of USB, which is a maximum of 1.5A, charging the big battery might take a while. The maximum current (charging my tablet) I have seen is 1,18A.

A quick calculation:

- Atom chip at full speed: 2W

- Screen at full brightness: at least 5W

- WiFi/Bluetooth/GPS/3G using all at the same time: 1W

- other stuff: 1W

Total current draw at 5V: 9W / 5V = 1.8A.

So at full power, it's probably impossible to charge the tablet!

A simple calculation shows that it takes: 8500 / 1180 = 7,2 hours to charge. And that is when you turn the tablet off.

My next step is to check the current draw when the tablet is fully charged.

Also, I doubt the charger can actually provide 2.5A. Chinese charger have always been crappy because they like to use cheap components which causes more voltage ripple.
[Teclast X98 Air 3G] namth56:
No, but I had to install drivers one by one. When I was with Windows 8.1 Pro, I got high battery drain in sleep mode. On windows 10, I don't see it any more.
[Teclast X98 Air 3G] FEGuy:
So I'm very interested in picking up an Air 3G or Air II, but I do have a couple questions first:

-Am I correct in assuming that there's no way to charge the device, aside from the USB port? There's no way to charge it while using USB devices, is there?

-Has anyone tried Team Fortress 2 on this? If someone has it installed and can give me an estimate of FPS at a couple different resolutions (set FPS to display in-game by setting cl_showfps to 1 or 2 in the console) it'd be greatly appreciated.

Thanks for your time.
[Teclast X98 Air 3G] namth56:
For the first question, Yes. try something like this: http://www.adafruit.com/product/961
[Teclast X98 Air 3G] Glamir22:
Hi, Im currently in the process of installing windows to this tablet, but I have a few questions:

-Do you know whether the Windows 8.1 with Bing is 32-bit or 64-bit?
[Teclast X98 Air 3G] LVL91:
Ok some more bad news.

When the tablet is fully charged, the current draw is about 1.1A when using the tablet.

So if the tablet is charging and being used, it's charging the battery with only 80mA:silly:

Charging the tablet while using it, is just stupid. Charging the tablet while continuously using it would take 8500 / (80*(5/3.7)) = 79 hours.

Btw, my last calculation was wrong. I used the current @ 5V, but I should use the current @ 3.7V (average li-ion voltage)

Anyways, charging is really slow unfortunately, and a I don't think a better charger is going to change that.
[Teclast X98 Air 3G] Glamir22:
I think I ****ed up the Windows installation, I closed the command prompt after the fpt package succeeded, but then when it started to install windows it asked me to press any key in shell, but using keyboard doesnt work and I cant connect the tablet to PC anymore. So it is in a continuous Windows installation loop, which cant proceed since I cant do anything.

Is there anything I can do?
[Teclast X98 Air 3G] LVL91:
Ok guys and girls, I made a video to determine whether your tablet has gpu issues and/or touchscreen issues.

Check it out:

Check if you have followed the tutorial step-by-step and make sure all drivers have been installed.

Try the update process again, I think the problem is not your tablet, but your PC, USB port or maybe USB cable.

1st: power off the tablet by holding power button for about 10sec

If wont help, try to connect with hdmi to the tv.

Keep in mind, that the tablet might still eat the battery power being bricked...

Firmware update

About google store issue, I have contacted the Aliexpress store where I got the tablet (the store listed as recognized in Teclast's website). The is their response;

Quote

2. so sorry, recently there are many buyer have repoted this problem. we have contact with Teclast ,

then they told that this tablet is nonsupport googel service, so sorry for inconvenience,we just know it now.

google service can't test in china, so we didn't know this problem.

so sorry make all buyer unhappy.

But the Teclast said that new firmware will come after a month.

Plz be patience, this problem will be solved soon.

Unquote

I also try try to root the tablet by following this video in youtube: /watch?v=36zMgmt25Fo

Couldn't find and download the vRoot but I used Iroot instead. I root couldn't root my tablet but I was able to use google sheets and documents which I wan't able before I try. I don't know why I have a limited knowledge to deal with these type of stuff. I did spend too much time to solve the issue but no luck for me. I hope said firmware will be issued soon and solve the problem at least for the tablet owners outside the China.

I would recommend to use a programmer device, that suppors low voltage mode: 1.8v, for this winbond flash.

Such as this one: EZP_XPro Programmer.

2 supercowz: pls extract the bios from the flash by a programmer and compare with the one extracted with FTP tool.

Also both here would be +....
[Teclast X98 Air 3G] supercowz:
the thing is i have old powerfull universall programmer from eetools (cost 1000euro at that time) but with Lpt port, and i dont have

computer with LPT port anymore and i dont want spend 1000euro again for the new model with usb :) ... anyway let take a look to EZP_XPro Programmer :)

edit : i just dig a bit and the CH341A EEPROM Flash BIOS USB Programmer CH341A should do the job, since i can operate in 5v and 3.3v, maybe need a small tweak ....

here the PDF abt CH341A :

http://www.oomipood.ee/drivers/ch341a_programmer/CH341_chip.pdf

and the eeprom chip inside the tablet is winbon W25Q64 support up to 3.6V

that why maybe it did work .... with russian and german ... need some test, my CH341A is on the way ....

anyway EZP_XPro Programmer seem cool ... i like it ... :) 30$ .. worth it :)

that remind me when i reflashed my Ps3 nand with teensy++ board, same problem 5v vs 3.3v ..

[Teclast X98 Air 3G] NuttyS:
Right, a proper post this time!

I recently got an x98 air 3G, it says it's a C9J8 although the Google store lists it as C9J6.

First thing it did when I started Windows was prompt me to update to Windows 10, that went fine so I booted into android to check that out.

It was laggy - I assume because of the bloatware so I came on here and found the latest rom.

Flashed it fine, have since removed it though as I realised I wasn't going to use it much.

My problem is I saw the bios update so flashed that too. Of course I then read more on here and low and behold it had messed my cameras up!

I went back to a lower bios and got the front camera back, but in Windows they're both upside down unless I change to normal landscape mode in display settings, which is very annoying as having the tablet that way up means I keep knocking the power button.

I've tried the uninstall and reinstall fix on here but it didn't do anything.

It's fine in skype/messages, but not in any other camera app.

I've searched this and other threads and have seen people were working on another fix, but can't seem to find if one has actually been sorted?

Hey guys! I did something stupid.

I have a teclast x98 air III and I wanted to put windows on it. I followed some guide for a teclast air II that said I just needed to make a windows 10 installation USB and plug it in and reboot, so thats what i did.

I got ACPI_BIOS_ERROR and a brick.

I did some more searching, and it turns out I think there is a way to unbrick it by using a usb chip reprogrammer thing with some software and the proper bios.

Could someone help me with a guide on how to do this please?
