I have flash the mirek190 rom v3.1 works fine but when i want power off the Tablet i cant do that well there is only Reboot and other things.

Can any one help me the install a power off point one the Menü ?

I mean at the Power Menü.
[Teclast X98 Air 3G] mr.pants87:
you can just hold the power button for 10 seconds or download xposed (it's in the OP) and then download APM (advance power menu) and set it up that way.

Yes, I have noticed the same issue with the brightness, any idea how can we solve this? I also think is somewhat related with the colours displaying on the screen...

Yes but with APM can i make that only under menü reboot. Two Clicks to power off.

Any one a other way ?

refresh rate

hello I have installed windows 8.1 by teclast only not android on my HG9N x98 air II, and I saw that I have to install dual bios to have the 60hz refresh rate with my gpu. I was wondering ... so many developers here cannot fix this simple problem? I dont want android and I dont want also to have lower battery life....is this really so hard to do?

Hi guys,

I just receive my X98. I noticed it is running on Win 8.1 with bing 32bit. Is there performance gains if install Win 8.1 pro 64 bit? How about the driver, any issue if reinstall Win? Also can I use back the Win key in this tablet for Win 8.1 pro?

when i do that i get: entering dnx mode. waiting for fastboot command... but my computer even after i installed the drivers can see that it is an intel andoid AD but with a (!) and i dont see my tablet on the flash tool. what can i do?
[Teclast X98 Air 3G] sbasil:
What OS are you using? The flashing tool didn't work for me in Windows 8 x64 (it wouldn't find and install all drivers) --> I had to install Windows 7 x64 and disable driver signing before I could flash anything. Also, try connecting the device to another USB port and even with another USB cable. I'm pretty sure your tablet isn't a lost cause yet. :)
[Teclast X98 Air 3G] PeppeBove:
It is better 32bit.

64 bit take more memory on our little Hard disk and give no advantages on system with less than 4gb of ram.

For key, you cannot use your windows factory key on pro version

Hi guys, 2 days ago I received my C8J7 (

I rooted it, it was in Rom 2.05.

- Is there any changelog since 2.01 (to compare with custom ROMs in OP), on witch ROM is based mirek190 rom v3.1 ?

- I've spent few hours on this topic, but I've not seen an easy way to dump partitions. AFAIK there is no CWM nor TWRP. Is there an "easy" way to backup partitions ?

Battery Calibration and Voltage

C9J6 Dual Boot: I noticed that when I switch between Android / Windows, the battery calibration is messed up again, battery is stuck at 7%. Although I recalibrated / fixed it. Anyone noticed the same?

Furthermore, when changing Critical Battery Action under windows to 'do nothing', the battery voltage increases to over 4V and capacity increases accordingly to a bit over 41k mAh. I don't fully understand how changing this setting is correlated with the battery voltage o_O. Any explanation?

I ended up using my "shure se535" headphone and at the maximum volume, then I could get a audible sound. But with my LG G3, my ears would be hurting at maximum volume with this headphone. Funny thing is, this headphone costs more than the tablet.

I have decided to bring it back for repair and will let you guys know if there is any improvement after it.

It must be ControlSet001

\SYSTEM\ControlSet001\Enum\ROOT\SENSOR\0000\Device Parameters\kxfusion

i have put that in the two ControlSet001 and CurrentControlSet and then it works.

But i find that at first not well it not work when i restore the Driver with Double Driver. (From that is have destroy any thing i can not say why and where)

Then have i restore Windows and use the other Driver like the video https://www.youtube.com/watch?v=rLjayeQJg4Q. (Click on install of the file at the driver foder)

It must be the Driver Package that is not store with Double Driver.

IF anyone is interested, got a video of the Tecalst X98 Air 3G Vs Cube i6 here: https://www.youtube.com/watch?v=NAs8t7KD1pQ

The Cube i6 is interesting, it's surprised me with a better build than the X98 Air 3G. It's got no soc issues like the freezing or overheating so far. And it's in BLACK :)

Downside is only 32GB eMMC for now, no hdmi out and the screen has a kinda anti glare coating on it :confused: The way Cube have done the mirco sim tray and the mircsd slot are nice, Teclast should take note.

Hopefully Teclast as busy working on a 9.7" retina tablets, this the new Atom X5 or X7 cherry trial, 4GB with a full sized usb .30 port now...
[Teclast X98 Air 3G] benbraun322:
Ha I hope your right but if you are I will be really upset because I just bought my X98 Air 3G.

I don't think they would release a tablet with the specs you described for a while though.

But if I really like my Teclast and I find it a suitable replacement for a laptop during university days I would probably buy the new one if it's within the same price range.

Camera and orientation Fixed

Hi Guys,

I got some good news. The camera has been fixed and with working orientation and touch.

http://bbs.teclast.com/thread-258210-1-1.html

Need to uninstall three devices and reboot

1. Kionix KXCJ9 Accelerometer SPB

2. Goodix Touch HID

3. Intel Graphics.

Then after reboot install in this order from the attachment download in above link.

1. Intel Graphics

2 Goodix Touch

3. kxaccel-win8-x86-dbg-intel.exe and registry. Once registry entry is done and reboot monitor will be reversed. I had to change registry to this value.

01 00 00 01 01 00 02

At the moment was on the windows 10 chinese image and tested this and works.

1. I am now going to test this on windows 8.1 clean installation and let you know of exact procedure.

2. Would be great if someone with default image or any other windows installation with default drivers tests this also and let us know of results.

48Mhz refresh rate not fixed with this.

Will keep you posted.
[Teclast X98 Air 3G] BoORDeL:
OMG YES IT WORKS FOR CAMERA.

Tested on windows 8.1 PRO ISO

Just remeber to copy in windows\inf folder TouchSetting.gt file (overwrite exiting one).

Anyway touch HID driver has a different behavior respect the old one.

I did not manualy change registry value for sensor because it was correct (anyway better to check)

Fix Playstore issue on new Android Firmware (4.4.4)

Hi,

Thank your for all your interesting contributions!

I would like to ask you one question:

Is there any way to fix the Google Playstore issue on the new firmware? What I have rooted the device, installed the google services and playstore and App2SD.

My problem is that when I try to make the playstore a system app, I get the message "/system: Not enough space". However I have plenty of gigs left.

Anybody has found a solution to this? Thanks for sharing!!

Other remark: Indeed the tablet gets barely warm at the touch and some benchmarks run even slower on my Air 3G than on my old X98. I think that there is some more headroom left for tweaking the turbo mode.

I have ordered an Air 3G Windows, maybe it will be better there.

regards,

Alex

[Teclast X98 Air 3G] Hendrickson:
Many thanks, can you please explain the reg edit? The bottom of my screen works well with touch, but the top half is reserved.

Here are the driver downloads without having to sign up on the chinese forum https://mega.co.nz/#!4Z9A3Tzb!mITSJDywAVE0nhuoDh7ISc9sSX0ilRH37CHPY-Cgs1U

As for the 48hz refresh rate, I think I got a step closer.

The new driver from this download (above) now ables CustomModeApp in intel GFX. In run, type CustomModeApp. I have tried to enter 1536 x 2048 at 60hz but it says I exceed the bandwidth limit.

Maybe a DTD regedit can fix to hack 60hz, at least we can now add custom resolutions too.
[Teclast X98 Air 3G] StardustOne:
The Geekbuying findings and fix attempt for the broken Google Play Store is only for the Teclast X98 Air II, and they do not work for the X98 Air 3G version of this tablet. I tried it. Not a chance.

Nothing works out of the box for Android for this tablet with 4.4, no wonder people desperately try to use it as a Windows tablet.

This is one fine example of a hardware that someone should never buy if it is intended to be used with Android, it is broken out of the box for everyone and Teclast does not do anything to fix this.

It is quite a sad story that the shops are still selling this product and everyone opening the package then realizes what mistake it was to order this in the first place. It is also unbelieveable, how positive the reviews for this hardware are, e.g. with tinydeal.com, there are currently 12 reviews and most of them are for the outdated and not sold anymore Android 4.2 version that came with the old CPU, they simply merge everything together to make it look good.

And the worst: my colleague has received his tablet a week ago and his status for the order is still Shipping. But you can only comment on the product when you have ordered the product and your status changes to received. I hope not too many are ordering this product before my colleague can rate this hardware with 1 star (there is also the Windows 8.1 version, available for the same price, but no one seems to even consider buying the Windows 8.1 version, but everyone with the broken Android one wants to convert it to Windows 8.1).

Sad story short, if you still think about buying this tablet, get the Windows 8.1 version, it runs Windows 8.1 out of the box and avoid the Android version at all costs because it does not work and it only is a waste of time to try and fix it with various information from people who might got lucky rooting and installing stuff without proper instructions.

[Teclast X98 Air 3G] Hendrickson:
Ok so whats a good tool to extract my monitor driver? I see its listed as a Color LCD, not generic monitor. So the driver used must tell the Intel GFX it can run at 60hz. If I can extract this air II driver and apply it to the Air 3G then using CustomModeApp, we should be able to run 60hz.

I am not sure, do you have better option/solution? KB is looking good, it is possible to buy white version, MS build quality used to be perfect.
[Teclast X98 Air 3G] benbraun322:
Yes I do :D

If you don't mind having the stand separately you can buy this one on eBay for $27

http://www.ebay.com/itm/310571683387?rmvSB=true

And its Logitech so its not going to break down on you, very nice quality Bluetooth KB.

But if I was planning on spending a lot of $$$ I would go for this one instead of the Micorsoft one, its only $50 instead of $80 it comes in white, and has a built in stand can SUPPORT 3 BLUETOOTH DEVICES!!!

Meaning if you use both Dual Boot of both Android and Windows then you dont have to re-pair the KB each time it has a little knob that you turn to choose which device it is connected to.

You can make #1 Windows and #2 Android and still have a third device you could pair it to!
