I was thinking that, seems it doesn't support it then. Oh well. 150mbps is still nice.

I have an LG TV and Widi works fine for me. But its 1366 x 768 max res on my TV, then if it is 1920 x 1080p It will not let me increase the resolution. Still it works fine.

By the way here are some high speed no password required downloads of the OTG files if anyone wants them:

I'm on C6J7 now and just Windows 8.1 at the moment with no plans to dual boot or switch to Android. But under the device manager, like my C6J6 I see the same GPS device:

Broadcom GNSS 4752 Geolocation Sensor

The info on the chip in my C6C7: http://www.broadcom.com/products/GPS/GPS-Silicon-Solutions/BCM4752

Maybe the new devices have it disabled in Android? I'm trying to find a decent GPS app in WIndows Store to test it really works.

ota update c8j7 2.00 -> 2.01 ?

I have the original V2.00_20141106 installed. Since the teclastautoupdate.apk only shows

an error when searching for updates I am interested in an incremental update from

V2.00 to V2.01 for c8j7. After that I could apply the 2nd incremental update given above.

Anybody?
[Teclast X98 Air 3G] agunghost:
I've got c9j7, and it's not a true tablet because of so many sensors are missing.

However, Gps is working tough without magnetic sensor. For this, I feel disappointed too :(:(:(

I have successfuly activated both windows and office. For office, I've got licensed for 2 devices for 1 year.

And also, I've installed android Amiduos in windows and interestingly, it gets antutu score around 19000. So, for virtualization, it still capable doing something great. However with the price of cutting storage down to around 1Gb......

For Activating Office365, you need a live.com account ? Did you have to put in a key or just go online and activate ?

Please elaborate how you activated ?

Can we backup the license details so that we can still use it after a fresh windows installation ?

Windows was pre-activated /OEM key for me.
[Teclast X98 Air 3G] agunghost:
I activated using a live.com email, but I'm not sure if we must use "live.com" account.

And I don't need any key, we just need to stay online.

As far as I know, once activated, the licensed will attach to email that we use to activate.

everything again.

My tablet is C8J7 Rooted so i don't know if it has any relation to the Techlast update failing.

It is 555mb so it seems to be a whole operating system update.

You will lose everything by flashing this update anyway as we dont have a custom recovery for this tablet.

Hi Hendrickson

Thanks
[Teclast X98 Air 3G] mnitstanley:
I ordered mine a week back and got C9J7 series from AliExpress seller, Tina Wu (CoolMZ.com). I am happy about that seller too especially for the fast, safe and cheap shipping to India via DHL.

It was delivered yesterday and I updated the Android OS via teclast OTA and also updated Windows 8.1 and there aren't any major bugs after the update.

3G has a connection glitch in Android which requires an extra reboot to connect to 2G/3G. Tested on Vodafone INDIA on Android as well as Windows. So it works.

I am pretty much satisfied about the C9J7 which got an OTA update dated 20141225.

Thermal Algorithms notifications do pop-up sometimes but doesn't slow-down or stop the ongoing operation.

I couldn't complete my Antutu test at first because 3D test froze but not anymore.

I suspect that some C9J7 also suffers from GPU problem. I am testing mine. Except for high end games, it works fine so far.

Update:

Riptide GP2 ------Failed :(

Real Racing 3 ----Failed :(

I haven't rooted the device yet which I shall but I guess, at present state also, it may not be that far off from a "rooted Stock ROM"

Check attachment. All I did was an OTA update.

Can someone build a rooting/unrooting zip which can be applied like an OTA update ?

Or

Execute a script via ADB ?

I am about to try this on my Air II...do you by chance know if your tablet was powered on or not? Mine is hard bricked and you can't easily tell if it's on or off, but I can tell if it's powered on or not cause the chips are slightly warmer if it's running, and get cold if it's off.

BTW, this is such a silly reason to have to go through this hassle as I am about 100% sure if there was a hard reset to BIOS defaults my unit would be fine. All I did was try some different settings. I guess now that I will soon have the clips and flasher and stuff I might be able to try stuff again and just be able to flash back. Really should be a bios reset though. Guess this is some sorta cost savings to not have a hardware bios reset....haha.
[Teclast X98 Air 3G] kaplaey2:

well within the build.prop file it says that "# ro.build.product is obsolete; use ro.product.device"

[Teclast X98 Air 3G] thehobit:
Thanks for the update. I'm about to get C9J7 shortly.

How clean is the stock ROM from bloatware? Did you install a new custom android?

Did you have to install the various fixes from the first page?

What about VROOT for rooting?
[Teclast X98 Air 3G] HDtracer:
To be honest I don't know if it will work with the update app. Probably not though.

You can always give it a go, but be prepared to have to flash/fix it with Intel flash tools.
[Teclast X98 Air 3G] mnitstanley:
You will get C9J8 if you buy it from this seller Pretty much the same but next newer batch.

Stock ROM is full of Chinese Bloatware and didnt have Playstore or Google Play services at first.

Even with Bloatwares auto-starting with boot, I have 40-50% RAM free. Data Partition size is only 6 GB !!

All I did was, checked for Teclast OTA update and applied it and rebooted and no major glitches or bugs at all.

Didn't have to apply even a single fix from first page.

I updated Windows also.

Haven't rooted it yet since it seems to break the future OTA updates (not that there are frequent OTA updates).

But since Data Partition size is only 6 GB, I will have to move game and apps to SD card. And bloatware cleaning is also inevitable.

So I am looking at 2 methods mainly to root

Method 1 as suggested in this post using X98toolbox

Method 2

[Teclast X98 Air 3G] Hendrickson:
No way of knowing 100% it was charged. But what I did was leave it charging overnight to insure it was hopefully charging it. If its on the area near the Cpu - the mircosd slot is warm. Hold the power button 10 seconds , then wait a 10 minutes and see if it's cold. If its cold its off.

Stupid there is no bios reset!

I've bought an SD card for my W8.1 Air II and installed a few programs. However, I realized that most of my 64GB were soon used, and I found it really weird. I checked the folders, and one of them showed a size of 571 MB and 581 MB when placed into the SD (what's usually displayed as size in disk). The other one had a size of around 9 GB (a Matlab installation) but it used almost 45 GB in the SD! Does anyone know why this is happening?

[Teclast X98 Air 3G] jcespi2005:
Should be caused by cluster size...

If you use FAT32 or extFAT with, for example, 64Kb cluster size, a 2Kb file is using 64Kb. A 61Kb file uses 64Kb also... So lot of small files with a big cluster size is not a good idea... If you use only windows, format the SD as NTFS with 4 or 8Kb cluster size... And give a try...

You can even change the resolution and also of course DPI.. 264 ppi will be a great looking for the tablet, but all for these, you need to ROOT the tablet

2) I had a bootloop and i had to reflash the ROM and it solved the problem, but i also know there is another way, by ADB commands, push the system.img via fast boot.
