thanks but i didnt understand, this one was only for C6J6 ?

[Teclast X98 Air 3G] peppemaria:
ehm .. I followed the steps .. I have not read anything about the BIOS version c8j7 !! so I installed the wrong BIOS ?? I did not understand o.o I should go back to Android and wait then?
[Teclast X98 Air 3G] SUMMERBREEZE:
earlier AIR 3G came with ID C6J6 and preinstalled Android but we had a WINDOWS BIOS already to flash windows 8.1 to C6J6 tablet. But now new AIR 3G come with ID c8j7 and there is no WINDOWS BIOS to flash yet for ID c8j7

different IDs , different files here we are talking about.. We discussed here (go back 15-20 pages before) what if we flash c8j7 tablet with C6J6 bios.. will it brick it or not etc... thats why we have been waiting someone who has got c8j7 preinstalled WINDOWS 8.1 official and DUMP the windows bios for us and share it
[Teclast X98 Air 3G] Informatic:
Please slowly explain what have you done so far.

What files have you downloaded?

Have you flashed BIOS as mentioned in the first post?

Does your back cover mention "C8J7" version?

Did your device ship with Android preinstalled?

It's quite important, because so far there has been nobody with C8J7 brave enough to try flashing C6J6 Windows-compatible (32-bit EFI) BIOS provided by Teclast.

If your tablet boots at all (even to chinese Windows installer) you still will (most probably) be able to recover Android, or just finish installation (and fix issues, take a look at the first post), without having to use external programmer (which would also require you opening the case, desoldering the chip, and everything, which, believe me or not, is not that easy...)

Could somebody with an account for the official bbs.teclast.com forum download the Android BIOS for the Air Version II for me? I am trying to sign up for a couple of days but I can't get any registration email.

[Teclast X98 Air 3G] billbmsn:
Once you have updated to Win 10 and see that it is activated, doesn't the Win 8.1 key in BIOS become irrelevant? Win 10 activation is based on hardware ID MS gathers identifying your device specifically, so once activated a key is never needed again.

http://answers.microsoft.com/en-us/...duct-key/33f31475-93b3-4d1c-812f-4b21fbd807a7

"Windows 10 handles keys differently. When you upgrade to Windows 10 via Windows Update from Windows 8.1 or Windows 7, the process registers your computers hardware, and qualifying OS with a Microsoft Product Activation Server. The device is then considered a Windows 10 device.

Subsequently anytime you re-install (or clean install) the installation checks with those servers, finds the unique installation ID and produces the validation"

and the Win 8.1 key, in BIOS or otherwise, would not work anyway for a Win 10 clean installation. I tried it. Invalid key.

I'm on BIOS 2.02 with no key in BIOS. The upgrade from the original activated Win 8.1 to Win 10 went fine. But I did not record the Win 10 key. THEN I inadvertently blew out all my partitions and had to rebuild Android and Win 10 dual boot from scratch with no Win 10 key. Ooops! Totally clean install of Win 10 from ISO put on bootable flashdrive. No problem at all. I just skipped a couple of requests it made for a key during installation, and Win 10 activated based on hardware ID MS recorded from my original Win 10 activation.

So, I'm not sure what this BIOS key injection accomplishes except perhaps going back to Win 8.1 at some point.

Hi, is it a problem?

we bought a tablet with the original windows license in UEFI BIOS, since there is a procedure to restore the key I think is profitable to share this info to the community.

You're not interested ? No problem!

If there are people interested, now they have the opportunity to restore the key in the UEFI BIOS. There are many users who have downgraded from Windows 10 to Windows 8.1 , perhaps it may be helpful.

I just shared my knowledge..

Help !

I'm so happy to have found this active thread :laugh:

I bought a

Teclast x98 Air II model

HG6N.

I never used this tablet so it’s brand new with Win 8.1 bing version with chineese language mixed with a bit of english.

I just like to upgrade my tablet to Windows 10 with a clean install with the latest Drivers/Bios Files and use it

in French

.

I browsed the web site/forums to find my answer but I’m just more confused :confused: about "Which files should I use" for my model HG6N ?

To add to my confusion some tell that HG6N front camera don't work with Windows 10 or/and Bios 2.02 and

I need to have the front camera working

.

I don't need dual OS.

What I'd like to know:

If there is REAL advantages at this point to use Win 10 over 8.1 with the Teclast X98 Air II model HG6N ?

Does the "stock" rom/bios have some issue losing power in "Sleep mode" with Win 8.1 and Win 10 ?

What advantage I will find if I upgrade the bios to 2.02 if I use only Windows ?

Thanks a lot for your help ! :cool:
[Teclast X98 Air 3G] tecknight:
#1. Flashing an image has no effect on the BIOS of your device, so it cannot erase any embedded Windows key.

What happens to existing Windows installations is all determined by the XML file you select.

If you select an XML file with the word partition or repartition in it, any existing Windows installations will be wiped during the imaging process.

XML files that contain neither of these words will leave your Windows installation intact.

If there is REAL advantages at this point to use Win 10 over 8.1 with the Teclast X98 Air II model HG6N ?

There are no significant differences in performance between the 2 OS's, provided you install the appropriate drivers.

In my opinion, Windows 10 is a "better" OS , especially on a tablet such as the X98.

Does the "stock" rom/bios have some issue losing power in "Sleep mode" with Win 8.1 and Win 10 ?

Yes, the amount of power consumed in sleep mode drops by up to 80% under BIOS 2.02 compared to stock BIOS. The ROM image does not have much effect on power consumption.

What advantage I will find if I upgrade the bios to 2.02 if I use only Windows ?

Significantly reduced power consumption in sleep mode and in some cases , a higher video sync rate

Thanks a lot for your help ! :cool:

Hi, I've run into trouble while using MFT to flash a Lollipop ROM (Teckinght's debloated 5.0.2) to a C9J8 Teclast X98 Air 3G. Namely, when I open the xml file in MFT and it says "ready to flash", and I plug in the tablet booted into DnX mode, Windows (Win10 64-bit) says "USB device not recognized", and MFT doesn't seem to recognize it either as it doesn't begin flashing. I used Tecknight's tutorial and I'm quite sure I followed every step written. Anyone encountered this issue so far or knows what to do with it? Thanks in advance and sorry if it's too noobish or was mentioned somewhere before, 1200+ pages are too daunting to look through and the search thread function didn't yield anything useful...

[MENTION=2651082]tecknight[/MENTION] or any other that can answer ;)

Could you reassure me with the Camera with my HG6N model...

I've seen lot of peoples telling the front Camera will not work after upgrading to Bios 2.02 with

HG6N

OR Win 10, is it true ?

If it's true do you know a fix (driver or file to edit manually) for the camera since

I need to have a camera

especially the front one ?

Does the advantages of BIOS 2.02 in sleep mode are for Win 8.1 OR Win 10 (maybe both) ?

Last could you tell me if those instructions to Update the BIOS from Windows ( Ihave no dual OS) seem safe:

first impressions

After one day from the installation of the mirek's 5.0 rom, I must say it has a lot of improvements from the previous version.

I just don't like the sound of the notifications: even disabling viper and lowering the volume value, they are distorted.

Also, I would prefer that the sliders of the volume would have more steps.

Another matter, I was trying to modify by myself, the SystemUI.apk to have 5 buttons for the navbar, but I didn't find, in the res folder, the right .xml file to edit: is maybe the navigation_bar.xml located in res\layout-sw600dp-v13\?

With stock BIOS the front camera will work in windows (8.1 & 10) and android 4.4.4

[Teclast X98 Air 3G] billbmsn:
Sorry. I never intended to insult you. Your instructions are great. I should have noted that. I did ask how useful injecting the key is and then added what I had come to believe - that getting the Win 8.1 key back into the BIOS does nothing very useful, as far as I can see. It isn't necessary to do the Win 10 activation when upgrading from Win 8.1 or reinstalling Win 10 clean. People have been spending a lot of time trying to inject the key perhaps thinking it really matters. I did recognize at the end of my post that it may help in the case of reverting to Win 8.1, as you suggest. If I am mistaken (as I have been many times before), please feel absolutely free to correct me. No offense will be taken. I'm here to learn like everyone else.

[Teclast X98 Air 3G] tecknight:
Billmsn,

I agree with you. I see no point in injecting your Windows 8.1 product key when you are running Windows 10. After the first time you install Windows 10 from an activated Windows 8.1, Microsoft remembers specifics about your system, so it will be uniquely identified If you ever install Windows 10 on it again, even if it is a clean install. Also, any time you make changes to your BIOS image, whether upgrading your BIOS version or just just injecting your product key, there is a chance (hopefully a very small one), but still a chance you could brick your tablet, so why tempt fate when you can just save the product key and type it in if necessary.

I think that it is great that Massimo is sharing his knowlege. If I was staying with Win 8.1 I would consider trying it, if I could ever get past the fact that the app is only in chinese

---------- Post added at 07:00 PM ---------- Previous post was at 06:52 PM ----------

OK, try this:

Boot tablet into DnX mode.

Connect to PC

Go to Windows Device manager.

1. How is device identified ?

2. Look at details in device Manager

What VID/PID are showing in device manager

Does it look like this:

On model HG6N only, upgrading the BIOS from stock to 2.02 will cause your front camera to cease working in Windows.

The front camera does work in Android, however.

---------- Post added at 07:24 PM ---------- Previous post was at 07:22 PM ----------

and your MFT is configured like this ?

Post your MFT log after you select an XML file and connect the tablet to PC

Looks like that too - and when I plug it in nothing happens. Windows makes the connected and disconnected sound though and it appears and disappears from device manager when I plug it in and disconnect it.
[Teclast X98 Air 3G] tecknight:
Your SoC driver installation has to be messed up then.

You have to do this then:

Boot into DnX mode

Connect tablet to PC

Go to Windows device manager

Right click the Intel adb device.

Select Uninstall

Check the box indicating "Delete the driver files for this device" then click OK

Once it has uninstalled go to Control Panel->Programs and Features

Find the package entitled Intel SoC drivers.

Uninstall the package.

Reboot PC

Reinstall SoC driver package included with MFT install.

Try again
[Teclast X98 Air 3G] wfan:
Right click and uninstall?

I've tried uninstalling everything and reinstalling but no luck. I've used your guide with the exception of using intel 1.09/1.10 drivers. 1.05 would display as unrecognised in device manager.

[Teclast X98 Air 3G] tecknight:
Fallen, based on the error message you are receiving, your problem is with the Intel SoC drivers, not the Adb drivers.

I recommend a HARD uninstall/reinstall of the SoC drivers.

@wfan YOU need to do this as well !!

Follow these steps:

Boot X98 into DnX mode POW, VOL+ VOL-- until DnX mode appears in small type in center of X98

Connect X98 to PC

on PC Go to Windows device manager

Right click the Intel Android ADB interface. You should find it under Intel Android Device

Select Uninstall

Uninstall dialog will launch. Check the box indicating "Delete the driver files for this device" then click OK

Windows should uninstall all USB drivers associated with the VID/PID

Close Device Manager and go to Control Panel->Programs and Features

Find the install package called Intel SoC USB drivers. Uninstall it.

Reboot PC

Reinstall Intel SoC USB driver package bundled with MFT install.

Reboot Windows PC again.

Try flashing your X98 again

Hi,

i have a Teclast X98 Air 3g ver C6J6.

With stock bios and android rom (ver 4.4.2) my battery (with almost no use of the tablet) remains for seven or eight days in suspend mode. This is aprox 0.5% battery drain per hour.

Yes, right click on the adb device in Device manager, then select uninstall.

As for the drivers, you should be using:

iSocUSB-Driver-Setup-1.2.0.exe---Ver 1.2.0 Intel SoC USB drivers

IntelAndroidDrvSetup1.9.0.exe---Ver 1.9.0 Intel Android Adb drivers

Each of these Installer packages are the latest Intel release of their class.

I have MFT and both of these installer packages installed on 3 different Windows systems and it works perfectly on all of them
