Buying Teclast X98 Air 3G..

When buying the device, should I prefer HG6N, C9J7, C6J6, or C8J7 model? Is it possible at all to choose at all?

If it comes with preloaded with Android and WIN 8.1, would it be possible to flash Android custom ROM leaving everything else intact?

Is it possible to install costume recovery?

Screen - I had the Cube 9x before which had unpleasant grainy screen, any comment on the screen of the X98? Thanks

Maybe this question is stupid, but I want to be sure.

I got C6J6 with dual boot, I installed Windows 8.1 Pro Full Version. I want to clean my tablet because I want to sell it. And I have a question: if I use option "Recovery" -> "Remove everything and reinstall Windows" all drivers will be kept or I will have to install it manually? Or maybe there is a better way to do fresh Windows installation?

My experience with c9j7

Hello thehobit,

My C9J7 is a dual boot, I have reinstalled android with the JCEspi2005 rom, without erase anything else. I did it because of chineese apps and play store issue.

Since there everything works fine.

For custom recovery i m not sure it will be possible because twrp or cwm are not supporting Intel cpu yet

For my part i find the teclast glass smooth. Much better that the onda v975i i had.

Concerning choosing the model...ask the seller to a precise model

:fingers-crossed:

Hi guys,

After new Windows installation (Windows 8.1 Pro - from 1st page) I've lost wireless display possibility...

I am 100% sure that I had this possibility on original Teclast Windows Bing - I believe that this is some drivers issue.

Could anybody please check on Teclast Windows type of wifi card in Device Manager (under Network adapters). I see Realtek RTL8723BS now (I didn't check that before reinstalling but I guess that it should be some Intel wifi card).

Any reply will be highly appreciated.

Second question: does anybody using Widi display with this tablet? (wireless connection with TV). If yes than what dongle (particular device/s) will work with this tablet?

You can wireless connect to your TV by Charm Bar (right edge of your tablet) -> Devices -> Project -> Add a wireless display

If you don't see this option it means that you have some drivers mismatch problem like I do. I am sure that option is available with original Teclast Windows Bing.

Which Windows 8.1 is better? With Bing or 8.1 Professional?

I am discussing with a seller on aliexpress, i almost convinced him to make a special hub for our Teclast for a cheap price :D

He also asked me to check for this cable, i think its called Y cable you mentioned before

http://www.aliexpress.com/store/pro...Cable-with-Micro-Power/221499_2017792055.html

I just couldnt understand from your post, how can we supply power to the usb hub? The charger of Teclast goes to wall and we need to connect USB into it and and charging input is microUSB... You mean putting a small converter (microUSB to USB) and like that into the HUB? I am not sure...

cheep USB OTG HUB with CHARGE function

I'm using this USB HUB.

When switched to OTG it works as expected under both Android and Windows.

When switched to CHARGE under Android it just charged, no otg funtion BUT I didn't test it enough to make sure it's not an issue I will describe below (installed windows and didn't go back to Android to check it).

When switched to CHARGE under Windows: it charged with otg function working (all three ports), but...switching to OTG and back to CHARGE disabled otg function until restart. Re-plugging wasn't enough.

Summing Up windows has to be booted with the HUB switched to CHARGE or otg function will not work while charging.

When switched to CHARGE under bios otg function will not work even when booted that way.

Charging is slow as already mentioned. I'm not sure yet if this HUB is making it worse or it's just the charger and cable. Anyway I suspect it will slow charging down. I'm not sure if you can actually charge the tablet with it or just slow down the discharge.

You mean finnaly full working TRUE DUAL BOOT?
[Teclast X98 Air 3G] BoORDeL:
This is a well known method for a true cold dual boot.

The trick consists in writing on the fly the firmware for the guest OS.

I don't like it but now they have added an automated way for writing bios on the fly.

I'm still waiting for a bios containing both 32bit and 64 bit UEFI INSTRUCTION SET for a real cold dual boot.

Hello,

since 28.12.2014 Teclast had updated the Playstore. See attached File.

I have the C9J7 model.

Now I am happy.
[Teclast X98 Air 3G] seba2000:
Thanks.

I am wondering what I missed then and now I have lack of wireless display possibility...

There must be something to be done...

Anybody have any idea? How to restore wireless display on fresh install Windows 8 Pro?

BTW, I can confirm huge battery drain on Windows (C9J7)

I disabled Windows Search (in services), disable Fast Start (in power options), muted volume (there is no requests then under powercfg /requests), even turned on Airplane mode and disabled bluetooth (in device manager).

Everything was useless - battery drain issue still exists (about 3-4% / hour with screen switched off). By 6 hours in night 20% of battery was consumed.

It seems like this tablet never sleep - screen is just switch off...

Do you use Windows with Bing from Teclast? I'm using windows pro and I have the same problem. Display after pressing the power button is totally off. Under Android the working time is normal, battery drain when tablet sleep is up to 5% per day it should be the same under windows. I think that windows from teclast should solve the problem, so I"m looking iao image. If it didn't help so it is a dual bios fault.

Ok [MENTION=286727]finas[/MENTION] will try and let you know.

But what about Play Store and Google framework ? Where is it on the home screen ?

Is the model no. C9J7 mentioned on back of your tablet ? Android 4.4.4 C9J7 is mentioned inside About Phone section. Where did you buy it from ?

I applied update via Windows update (250 MB).

The leather case I got actually opens to the right side and is non-magnetic !!

Update:

Teclast Auto update was successful. ~12.76MB download.

After reboot the Google Play Store & Google frame work were auto installed but had to update it to latest version.

Ran Antutu and it froze during final Video test. Had to reboot but still gave a score of 28500.

Installed CPU-Z and it reports that only Accelerometer is supported. Antutu also reports the same. No GPS ?

CPU-Z reports the battery capacity as 4980 mAh !! But Windows reports it 31000mWh which is more or less 8500mAh.

Other C9J7 owners also please check and confirm these points.
[Teclast X98 Air 3G] smartchip:
Good to know. I'm currently talking to the seller and compiling evidence that the freezing problem doesn't happen on every tablet. They gave me the canned reply that some games are not properly coded for Intel processors.

I'll update if/when I do get a replacement. Besides that 3D gaming issue, and having too little memory for dual boot, I'm starting to really like this tablet.

For those looking for a good case, the Logitech Ultrathin Folio (without keyboard) works well.

Hello all,

I have tried to find information about sleep problem in Windows and only found the info available on first post of this thread.

I have followed instructions, and now, when launching powercfg /sleepstudy, a report is generated. But when Tablet goes to sleep, I still see the screen doesn't go off, so the battery drain still present. When gone to sleep, the screen is still on, but black, so u can see the backlight.

Does this happen also to you? Anything I can try to switch, tweak?

Thank you very much for help.

Can you confirm this on your C8J7 & C6J7 ? If possible please post a screenshot of Antutu Sensor info.

AFAIK the Teclast X98 Air 3G Win8 only models don't have GPS sensor which makes me wonder if C9J7 is just an officially software updated version of C6J7 !!! :confused:

Whereas it was meant to be an officially software updated version of C8J7 to match the HW part :confused:

The sensors are missing it seems, huge disappointment and if true then it is a case of duping customers.

Office 365 is a genuine licensed version ? I clicked on the Microsoft Office icon on metro screen and it took me to a window with 2 buttons in Chinese.

It also mentioned a date of June 2015. Is this a 6 month Trial version ?
