With a few exceptions, I find the performance to be similar to Windows 8.1 and the overall experience to be better, because, frankly, Windows 10 is a better OS, especially for a tablet.

The exception that comes to mind is:

Chrome browser which performs very poorly in Windows 10

---------- Post added at 12:46 PM ---------- Previous post was at 12:37 PM ----------

Based on the history of the device, my educated guess is that it is not upgrading because your Windows 8.1 is not "really" activated.

Upgrade to windows 10 from stock teclast windows?

I was wondering if the teclast stock windows can be upgraded directly to windows 10 without reinstallation?

And does windows 10 consume more storage than windows 8.1?
[Teclast X98 Air 3G] juanmaasecas:
I said it last week, Windows 8 performance is better. Animations are more fluid, the Os is a little bit faster and chrome is awful in Windows 10, while it's quite usable in Windows 8...

Still working on it. I suspect it is a driver issue, since I have seen a number of driver issues in Windows 10 between the four machines I have upgraded. Although there also seem to be some occasional problems in Windows 10 itself, so we may have to wait for Microsoft to start issuing updates.

Issues after Bios 2.02 flash

Hello Dears,

I flashed my C9J8 Tablet with the bios 2.02 and implemented the Mike190 5.0 V3 early beta with real success.

I'm now waiting for the Win10 download completion in order to upgrade my windows partition.

But i figured out an issue: no more cameras working nor in android neither in windows system.

Is it due to the rom flash 2.02 ? how can i correct this issue ?

Thanks for your support,

DcaMan
[Teclast X98 Air 3G] juanmaasecas:
Front camera won't work either windows or Android because of the 2.02 bios. Downgrade your bios if you need it... Rear camera doesn't work in lollipop mirek's v3, but it does on his kitkat roms and it also works on Windows (although probably inverted).

[Teclast X98 Air 3G] daWyrd1:
sounds like me.

i flashed 2.02 bios on my c9j8. no matter how a usb stick is prepared it never shows up in the bios for booting. i used the old fashioned win8.1 install from the first page of this garbage pail thread. copy the winpe files from the stock win8.1 to a fat32 usb stick. plug that in a usb hub with a usb kb and a ntfs usb stick with the win8.1 image. reboot and windows starts installing. upgrade after installation.

good luck

Bios 202

Hi,

I tried the BIOS Update 2.02 to a x98 3g (c5j6) to install from Post # 9792nd

Finally, I have made this

** BIOS flash SUCCESS !! Press and hold power button until X98 device shuts down !!

13 Then do this:

IMPORTANT: Hold the power button until your tablet Powers off Disconnect from tablet PC..

14. Wait 30 seconds and power back up while holding tablet Vol +.

now it will not boot.

sorry for my englisch

HELP
[Teclast X98 Air 3G] daWyrd1:
nope, it didn't touch it. after win8.1 install i did have to go into the dual boot screen manually (vol/power) and uncheck win8.1 so it'd dual boot boot by default.

"Contact" application missing

MIrek190: I have installed the last version of your Android 4.4.4. version 4.2 but the "Contact" application is missing: did someone had the same problem ?

This application was included in your early beta Android 5.0 but I had to uninstall it due to frequent freezes.

It's too bad because Andoid 4.4.4. seems to be very smooth but I cannot use this ROM without "Contacts".

Thanks anyway for your continuous efforts to provide ROM for our X98 tablets !

Hello, I want to thank you all and especially the developers for the work done.

Recently I've decided to install Mirek's custom rom v4 on my c9j8. So I've flashed bios 2.02 with success and after that the custom rom with intel mft. The rom was flashed succesfully as shown by mft log but unfortunatelly now when booting to android the tablet is stuck on the tpad logo screen. Boot in windows works ok. Any ideas how can I make the tablet boot to android again?

Thank you!

Sometimes the videos play fine and other times they freeze up like this ?
[Teclast X98 Air 3G] alborto:
Yes
[Teclast X98 Air 3G] tecknight:
Assuming you mean:

Yes, sometimes it works fine, other times not so much.

Here is what I want you to try next time it happens:

Immediately go to settings: WiFi and turn off WiFi for 15 seconds. Then turn it back on. Once WiFi reconnects, try the video again.

Let me know what happens.
[Teclast X98 Air 3G] alborto:
Doesn't work,i need to reboot
[Teclast X98 Air 3G] tecknight:
OK. Next time it happens check your internet connection bandwidth.

Try running a speed test.

Launch a browser and go to:

www.speedtest.net

You will need to run a test when it is working also.

This will tell us whether you have internet connectivity with sufficient bandwidth when your problem occurs.

Thanks for help.

But what when I have already installed Windows 8.1 with Bing?
[Teclast X98 Air 3G] im4u2nv:
Thank you Petruccig and Frontier for your hard work....

I am just wondering what is the difference between the Chinese Lite ROM and the original one...i understand that the chinese bloatware were removed in the Lite...do they have the same OS version? Also for the Lite ROM, are we still be able to upload OTA?

Seems like after we root...we can NOT update through OTA...sorry i am just a newbie here :).
[Teclast X98 Air 3G] HDtracer:
It is the same as the Teclast 4.4.4 release just without all the crap and a different launcher.

I dont think it will do OTA updates. It doesn't even have the Teclast update app in it.

I dont think the standard ROM with root access will do OTA updates either (as with virtually all rooted phones/tablets)
[Teclast X98 Air 3G] im4u2nv:
Thank you for your reply HDtracer! but the post said that after we install 4.4.4 from Teclast, we would need to do a small OTA, right? SO it means that if we are using the Lite ROM, we can' t do update because we don't have the Teclast update app?

I am planning to flash the 4.4.4, do the OTA and then root..that's what i did to my current x98.

C8J7

Is the C8J7 the dual boot version of the x98 air 3g?

Because over at this review of the dual boot x98 air 3g http://articles.imp3.net/64947-1.html

There is a image of the dual os x98 air 3g http://images.imp3.net/article/2014/reviews/teclast/x98air3gdouble/04.jpg

If you zoom in you can see that the ID says C8J7
[Teclast X98 Air 3G] im4u2nv:
i am currently updating the BIOS (Android) to the latest one...it has been 15 minutes and the screen still says 'Upgrading, this may take a few minutes...'

Any idea how long does it normally take to upgrade the BIOS?
[Teclast X98 Air 3G] HDtracer:
Are you doing it ota? I flashed it manually with the ifwi app and it took about 20 seconds.

I never managed to get the ota that is mentioned in the OP. The update tool always said undiscover new version so I did it manually.
[Teclast X98 Air 3G] im4u2nv:
I did it manually also..using the IFWI app...i downloaded the bios from the link by Frontier...it's weird..i tried it several times and it just said Upgrading for the last 30 mins or so..

Basically i did the following:

1. Copy both files to the devices

2. Install IFWI app

3. Open it and browse it to the BIN file, loading the file to 100%

4. Tap 'Update', and it shows 'Upgrading' but it just kept circling...

The x98 is still at 4.4.2 and rooted. No other changes have been made, no other application has been installed...

weird..
[Teclast X98 Air 3G] HDtracer:
All of the above is correct but probably isnt going to to work on 4.4.2

It is a bios that you have to install after the 4.4.4 upgrade.
[Teclast X98 Air 3G] im4u2nv:
Yup...i just realised it when i read the bios name...it is indeed for 4.4.4...

I have now upgrade to 4.4.4 and apply the bios...any way to tell how the bios has been updated succesfully? Seems like the boot up screen are the same as before..

Also i tried to do OTA upgrade before rooting..and the Teclast Update said no new version...

Also i tried to run x98 tool box..the .bat file..it run but when i select 'e' to Root the tablet..it won't do anything...should i put the tablet in the dnx mode or something?
[Teclast X98 Air 3G] HDtracer:
Yea dunno how to tell because all the version numbers stay the same.

You have to make a folder (on desktop or somewhere) and unzip the toolbox.zip to it, plug the tablet in and then run root-me.bat, press enter and that should be it.
[Teclast X98 Air 3G] dmandic:
To answer myself, i see in review that Windows in dual-system X98 Air 3g are 32-bit (you can see it in Cinebench image).

It surprises me somehow because i was on impression that in order to realize true dual-boot, there would be needed to install 64-bit Windows on 64-bit UEFI that supports Android?

Or it is possible to boot 32-bit system from (Teclast-modified) 64-bit UEFI?
[Teclast X98 Air 3G] im4u2nv:
THank you HDtracer. I did that and the command prompt screen said

.

adb server is out of date. killing...

ADB server didn't ACK

* failed to start daemon *

error: unknown host service

.

. If ID above - 0/root, Everything will goes well.

. If otherwise, press CTRL + C to cancel.

Press any key to continue . . .

WHen i comtinue..it just said adb server is out of date. killing...
[Teclast X98 Air 3G] HDtracer:
Hmm I wonder if you need the ADB drivers.

Have a google for minimal adb and fastboot program. It is on XDA somewhere as well.

Might just be easier to download the chinese version of vroot, it works easy.

Just temporarily disable antivirus and possibly firewall if it doesn't go to the root screen after doing its file check thing.
[Teclast X98 Air 3G] im4u2nv:
I think I already have one because i can flash using the Intel tools, right?

Anyway i managed to root using old school method by having Kingroot and Vroot...works well..

After all this though i still couldn't find any update v2.0.1 that Frontiers mentioned...i run teclast update but no new version was discovered. Any idea? Since OTA doesn't work it would mean that i have to reflash the whole tablet and install the whole application again to update OTA so i would really like to have the OTA first before installing all my other applications.
[Teclast X98 Air 3G] HDtracer:
Dont worry about 2.0.1 Teclast withdrew that version after a day or something.

2.0.0 is the newest version.
[Teclast X98 Air 3G] im4u2nv:
Ah ic,,,no wonder i couldn't get it...thank you for your help mate!
[Teclast X98 Air 3G] HDtracer:
Haha no worries. I went through the same thing trying to find that version as well.

Im not sure if flash tools adds the ADB drivers or only the Intel ones.

I had to download minimal adb prog to get a proper adb connection for pulling some other stuff off the tablet.
[Teclast X98 Air 3G] Killa-Bee:
have you Installed it on the Teclast Tablet?

does it work?

can you root the tablet with this ROM? if true with what tool? the same Toolbox as we use with our existing ROM?
[Teclast X98 Air 3G] mirek190:
After I flashed new bios on tablet and installed rom 4.4.4 lite.

I was installing on my x98 air 3g a tons of apps - including games yesterday.

I'm really surprised how everything works great !

For instance :

WinRar test has 1600 KB/s :D my note 3 has only 1100 KB/s - amazing !

GTA SA - everything on MAX settings - playable 25 -40 fps !!! - my note 3 on max settings is slow around 10 - 15 fps

Aspart 8 is the only game I found on max settings is choppy BUT you can just change resolution for that game and is fully smooth ! incredible !

I made video - https://www.youtube.com/watch?v=jIlw8rym53A&list=UUZrzmJGPYsbqhq4CkVLaNAg

No issues at all !!

Battery is very good - I was afraid about deep sleep - but works great no any drains !!

For such price and quality - the best tablet ever !!! :victory::victory::victory:

I was curious and made 3d bench on lower resolution

As fast as Samsung Galaxy S 5 hehe Nice !

[Teclast X98 Air 3G] agunghost:
I have X98 32Gb version.

I have also encountered the same message. The main problem is that it needs more available storage space for installation process.

So, anyone having 32Gb should free up more space (at least around 6 to 7Gb in order to upgrade to windows 10).

Before upgrading, backup your windows serial number using key finder magical jellybean, back up entire partition using macrium reflect (free version).

For this purpose, I'm using SSD storage for faster process.

Then, I just upgrade with option of keeping user file safe, choosing Home edition - 32bit version and create ISO file.

This ISO file is directed to external storage (Flash disk or SSD storage).

Using Rufus, I write an 8Gb USB Flash Drive using ISO file created from installation process.

To install, just clik "setup.exe" in the root folder of flash disk. During the installation, I don't have to input windows key and It's been activated in windows 10.

After installation, VGA driver is not installed by default. Therefore, we just need to update driver using previous windows 8.1 intel vga driver or using driver from Techtablets.

Windows 10 is great, but with only limited storage.......ehm....not sufficient. After installing Office 365, I only have aroud 300 to 500Mb left!!!

It's because I keep windows 8.1 version just in case I want to revert to older version.

So, before upgrading, make sure that you have:

1. Back up existing partition, and external storage (at least 32GB)

2. Back up windows key

3. USB flash disk ( 4Gb is enough).

4. Download Macrium Reflect free, Key Finder magical jellybean, Rufus.

5. Braveheart (just in case you bricked the tablet... hehehe)

However, I need help. How to boot into USB flash disk?

I have backed up using external storage and macrium reflect. If someday I want to revert, I can rewrite the partition using macrium reflect. However, I don't understand how to boot to USB Flash disk..
[Teclast X98 Air 3G] dagrim1:
I just went with the media creating tool, 32bit version: http://www.microsoft.com/en-us/software-download/windows10

I choose to 'update this computer' and all went fine (except indeed vga driver and it took a while). After that I choose to reset, keeping user data, to clean stuff up and now after installing most of my stuff again (nothing huge though) I have 29.1 of 37.5GB free. When upgrading I believe a lot of "noise" from windows 8.1 is still remaining. There's also a lot of update info and files after updating to 10, getting rid of that with disk cleanup is a nice option too.

[Teclast X98 Air 3G] grayfone:
I did NOT upgrade to Win10 from the stock version, but I can tell you that Win10 does start/upgrade according to the language you set in non-unicode settings and the country in international options (I had japanese as non-unicode setting and country set to japan on my desktop pc and the update started in japanese, and I had to swap to my own language after it finished updating), so as long you set your country, non-unicode settings and language/keyboard to the correct one before launching the update, you shouldn't have any problem. You can always rollback to 8.1 if anything goes wrong, though, directly from win10.

As for drivers, if you had all the drivers correctly installed on win8.1, the only driver the tablet needs is the Intel graphics driver, which the tablet will eventually download from Windows update itself (probably will download it before the whole update starts if you allow the updater to download the updates). The driver is basically beta, but works decently. It's slightly slower than win8 one, but since it's a recent system intel will probably update it soon.

I just got my Teclast X98 Air II (64 GB) (Model HG9M)

I'm really excited to finally play around with it.

It seems to me that I actually got Windows Bing 8.1 (9600) installed as my stock Windows because everything is in english with a chinese language pack installed (in the region and language section).

So in this case, I'm planning to upgrade to Windows 10 and flash Mirek ROM. I've seen the video uploaded by Techtablets that reinstalls the stock windows to windows 8.1 bing and flash a custom rom. But in my case, I think the process would be different. How do I flash Mirek ROM without interfereing with my windows?

1) Do I need to flash the bios 2.0 both in windows and in android?

2) Do I just use the Intel manufacturing tool to flash the Mirek ROm? Or do I need to do something before then?

a) Can I repartition the size without interfereing windows? Meaning I want to make windows storage bigger than android. Currently 33 Gb was partitioned for windows with 29 GB of free space. Is that how much windows 8.1 consume ( around 4GB)?

3) How do I get the product key from windows to upgrade to windows 10? Note - I have already activate it.
[Teclast X98 Air 3G] articsilverfox:
I think folks expecting Windows 10 to be faster are being a tad naive

Never in Microsofts history have they built a new OS for older hardware, their new OSes have always been designed for the very latest/future hardware in mind.

In fact i think its just as often seen as the opposite so that it encourages a new PC/Tablet purchase thus triggering a new MS OS licence sale for Microsoft..

The only gains in speed to be had are from a fresh install with less old software installed/clutter weighing it down.

I am constantly surprised by the naive views people have of MS, the only reason there was a huge gap between the release of Windows XP and their following OS was because Microsofts stock price was doing so well. Historically MS only respond to new software releases when their stock price stops rising on long term average, its such an accurate system you could set your clock by it, its never ever had anything to do with technology advancement in general...

Bios 2.02 Cameras issues C9J8

I was so confident about the bios 2.02 for my C9J8 (I haven't read about this camera issue before) that I haven't made a bakup of my stock bios.
