HELP !

I’m new to the tablet world. 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 want 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:

I read about various ROM/FIRMWARE versions, various Drivers versions and I’d like to know if it’s better for me to upgrade the ROM (I don’t need dual boot) and update some drivers or install some utilities ? If yes could you give me the links.

Also since I have this model ”HG6N – Windows (32G) – Camera reversed” does I need to do something special to fix the Camera everyone talk about?

I have already downloaded Windows 10 Fam Ed 32 bits in French via the WinMedia Creation Tool. Does I need another version or it will be fine to boot with a USB drive to install Windows ?

Best Regards !
[Teclast X98 Air 3G] massivekind:
First of all welcome ;)

Updating to windows 10 is nothing special, it's very easy.

Why (almost) everybody is updating there bios to version 2.02 is because the battery has less drain in sleep mode. I did this also ;). The 2.02 BIOS is a dual boot bios but that's not a problem. You could remove the android partitions in windows. For updating your BIOS check the forum on xda for the x98 3g, this forum is a mix of 3g and air ii users

I updated the tablet also to windows 10 and didn't need to install any drivers. If you need the drivers anyway go to the website from techtablets.com.

And download the drivers for the 3g.
[Teclast X98 Air 3G] Mikha777:
Thanks a lot for the quick reply ! :good:

I will give it a try this week with a clean install from a USB Stick, I was affraid to install a wrong Bios file and brick the tablet.

Regards :o
[Teclast X98 Air 3G] massivekind:
There is always a change to brick the device.

Good luck
[Teclast X98 Air 3G] Mikha777:
I found instruction to upgrade to 2.02 but they are to update on the Android side ? :confused:

Since I have HG6N model with only Windows do you know where I can find step by step instruction to know how to install the 2.02 ?

Regards :)
[Teclast X98 Air 3G] massivekind:
U could ask on the air3g forum. They could help u better because I think there are more people, which had the same problem as you :o

Help with Windows 10

I have an Air II HG7N. I allowed it to update to Windows 10 via Windows Update. Now I have 3 problems. First, although I selected English, almost all the sub-menus are Chinese. Second, I have no auto-rotate. Third, the drivers are bad--my wi-fi seems to be very slow and drops often.

Is there any way to fix these problems?
[Teclast X98 Air 3G] Mikha777:
I should update this week (HG6N) and will give you some news on "how it was" for my update and also I will leave you my drivers versions.

Which Bios do you have ? I will install 2.02 bios. and will make a Clean Install from a USB drive.

Regards :o
[Teclast X98 Air 3G] raymikeva:
I also installed the 2.02 BIOS. I did it after the Windows 10 update, if that matters.
[Teclast X98 Air 3G] microb77:
If you go with 2.02 on the HG6N the front camera woll not work in Wndows 10.
[Teclast X98 Air 3G] Mikha777:
Do you know if there is a fix since I need the front camera ? :mad:
[Teclast X98 Air 3G] massivekind:
At the moment, there is no fix for that. But they are experimenting with an other device.
[Teclast X98 Air 3G] intre:
I'm quite happy now. So as Windows 10 was not running as smooth as W8, I decided to rollback. After a reboot I got the error 0xc0000225. So now my tablet is useless.

I think I'll try to install Windows 10 from scratch. Is there a W10 factory image with embedded drivers for this tablet? The w8 version was the only way to make it work fine. BTW is a Windows-only HG9N.

Ty in advance.

[Teclast X98 Air 3G] massivekind:
Download the wibdows 10 driver packets for the 3g on techtablet.com in the zip there are 2 folders for 2 different camera's. Also you could try to download the windows 8 drivers for the air ii and try to install the camera driver from there

:cool:;)

---------- Post added at 08:04 PM ---------- Previous post was at 07:54 PM ----------

If windows 10 was successful activated you could install a clean version and login with your account. Also you could install the drivers for windows 8 if necessary from techtablets.com
[Teclast X98 Air 3G] intre:
Yes it was activated. Why not the Windows 10 drivers from "X98 Windows 10 stock image factory drivers dump.zip"?

[Teclast X98 Air 3G] intre:
Finally I managed to do a fresh install of W10. Now it seems a bit more smooth, though I don't have any program installed yet. Still got the problem of the battery meter, it only shows the remaining percentage when I switch to power saving mode. By the way, it looks like today 29 was released the W10 version of Intel drivers. Anyway, I still got the brightness problem. The brightness of the screen changes by itself when I switch from darker to brighter images. I had that problem too but I solved it by installing the official w8 from the vendor.
[Teclast X98 Air 3G] massivekind:
Go to energy settings current profile and click on advance. Now search for display ( or something) and expand this options, search now for adaptive brightness and set this to disable :cool::cool:

Update Only the BIOS and Clean ANdroid.

Hi,

i am a very happy user of a HG7N (NO 3G) tablet, i have update to windows 10, i am satisfied and it work's great, my only problem is the battery drain on Windows mode and i want delete android.

My request:

1. how to update ONLY the BIOS of the tablet (to solve battery drain) ?

2.how to DELETE Android partition to recover space ?

Thank you to all !
[Teclast X98 Air 3G] massivekind:
Search in this forum on " update BIOS 2.02" you will find a post from techknight (I believe) and follow the steps. Be aware that there is a change that your front camera won't work. To install the new BIOS you h have to flash it via android.
[Teclast X98 Air 3G] MrRimmer:
For me, at least, with H6GM changing to BIOS 2.02 has not solved the battery drain issue (Windows 8.1).

Update to Bios 2.05

The HG7N is not affected by the ACPI bug in Bios 1.07 and higher that affect HG6N + HG5N so his Front Camera will work with BIOS 2.02 and the drain issue will be fixed too. :D

Another thing you could do to help to fix the drain is to follow those steps:

Teclast x98 air II HG5N doesn't boot

Hi there.

I've been using the x98 air ii (HG5N) for quite some time now. I recently flashed the 2.02 dual bios succesfully., and wanted to install windows 10 x64 on it.

While the tablet was trying to boot windows install from the usb, it's screen suddenly turned off. Right now it doesn't boot anymore. I know the tablet would probably not install the 64 bit version, but i still wanted to try it. Down below are the things i already tried:

Hold the power button for 50 seconds. Hold it with volume down. And hold it with volume up. No sign of live.

Disconnect and reconnect the battery from the motherboard. Still no life.

Tried it with connecting the power supply. No sign of life.

The battery was 60% charged. So an empty battery is probably not the cause.

Search this thread / google for similar problems.

Can someone please point me in the right direction what has been the cause / how to fix it? A bricked bios doesn't seem the cause to me because the device didn't get bricked while flashing the bios (bios was flashed succesfully). Thank you in advance.
[Teclast X98 Air 3G] Mikha777:
Unfortunately your tablet is bricked now, attempting to install a 64 bit Windows on an X98 is known to corrupt the EFI BIOS and brick the tablet. :rolleyes:

The only option you have is to get an external USB flasher and flash it from a PC.
[Teclast X98 Air 3G] Arcenon:
Thanks for your reply. Getting an EEPROM flasher it is.
[Teclast X98 Air 3G] hindibuff:
Hello all,

Very new to this tablet so please pardon if I ask questions that seem rudimentary. In reading the forum, I could not find answers related to my issues, so posting them here.

I have a Teclast HG8N tablet that I have a few questions about:

1. Is there a lolipop update for it out yet?

2. I have a battery drain problem in android and windows ( or is just a small battery). Read some posts about updating bios. But:

* How do I find out what bios I have (I don't have an external keyboard to plug in). Either in widows or Android?

* What is the latest bios to update to how do I get it?

3. The plug for headphones seems to be strange. If I plug in a three connector headphone (from my phone), it doesnt work. It only works if I plug in just the two connectors (meaning don't plug it in all the way.) A minor inconvenience but wondering if anyone else encountered it and if there is any resolution to this.

Thanks so much!!

Which part of ROM

Hi there,

I need a small help.

Have s Air II HG8N dual OS.

I flashed to X98_Air_2_android_5.0_mirek190_v5.0-ultra-light, it looks pretty fast, stable (I dont care about camera).

The point is, that during the flashing I have sudennly droped my Windows8.

When I open this rom, I can chose between : flash-full_with_REPARTITION / flash-system_only_WIPE_DATA / flash-system_only_NO_WIPE_DATA

I dont know, if this was the bad step, but i chosed flash-full_with_REPARTITION.

I have two of these tablets, so dont want to make this mistake twice.

Thanks.

Teclast has released Lollipop for the HG9M. When I installed it on my HG8M, neither camera worked. Still, they might work on your 8N, but it appears cameras are a common problem for the X98 under Lollipop.

http://bbs.teclast.com/thread-397112-1-1.html

Also, over on the 3G thread, mirek190 has released a heavily modified Lollipop. I had the same camera issues

http://xdaforums.com/showpost.php?p=62483840&postcount=12094

To see BIOS version, from Windows, get into the All Settings menu, Update & Security, Recovery, Advanced startup, Restart now, (wait) Troubleshoot, Advanced options, UEFI Firmware Settings, Restart. The main page of the AMI BIOS setup should open after a few seconds, and the 4th item under BIOS Information should be "Project Version" with the tPAD BIOS version shown to the right.

Teclast has not released any BIOS recently for public installation. They have pushed firmware updates via their Android update app. It's not clear that these updates fixed battery drain issues. Many people have installed a BIOS version 2.02, which almost always resolves the battery drain issue.

http://xdaforums.com/showpost.php?p=61719173&postcount=9792

You should read all of TecKnight's tutorials...

http://xdaforums.com/showpost.php?p=61731608&postcount=9841

However, for me, and possibly you, 2.02 kills the front camera in Windows. Still, I run 2.02 but I run a KitKat release created by mirek190 because the cameras work, unlike Lollipop.

http://xdaforums.com/showpost.php?p=62024241&postcount=10608

Yes. You need either a iPod/iPhone type earphone or an adapter plug like this one:

BIOS 2.05 and Windows 10 64bits

Well, I have a question for all the people who has delivered the new BIOS 2.05. Is your windows 64 bits?

I was one of the guys who tried to install windows 10 x64 and see what happened with the BIOS 2.02, and test it two times because it's incredible. I had to reflash the EEPROM.

Now there is a new BIOS, have any test with this new BIOS if the windows is x64?

In BIOS 2.05 it is just minor modification so

don't try to install 64 bit Windows

or your will brick it again ;)

Ok, I get it when some other user tell me which version bring in his new Teclast x98 Air II.

Sorry, only for take information, because I want to edit the BIOS to allow a Windows x64. We have seen that there is a process into BIOS to check if a Windows x86 or Windows x64 is executed. But how do you want to dissasemble a BIOS which is signed by Teclast? I think that you are trying to follow the same way that me xDDD

UPDATE about BIOS 2.05 for X98 with GC2235 Front Camera

UPDATE about BIOS 2.05 for X98 with GC2235 Front Camera

The problem with BIOS higher than 1.03 is that the front camera GC2235 is not enumerated in the ACPI/DSDT of the BIOS, there is only the OV2680 that is enumerated. So I will insert GC2235 device in the DSDT so it should be recognized and initialized properly on the Windows side since Windows use the ACPI tables to find the devices on the hardware.

For Android/linux I don,t know a lot about it since I don't use it, I know DSDT tables are used too but I don't know to which extent. :confused:

If I'm successful to build a new BIOS2.05.bin with the modified DSDT it could work on both OS Windows and Android, it's not easy (at least for me) to find the tools and knowledge I need to be successful but I can say I'm very confident. :cowboy:

For the Windows side I can inject the fixed DSDT part in memory when windows start without modifying the BIOS, it's less elegant but it work. :D

Worst come to worst I will come out first with a fix only for Windows where the fixed DSDT is injected in Windows at start and later I will come with a complete BIOS fixed.

If you have any question feel free to ask. :cool:

Hi I ordered a Teclast x98 Air ii 64gb version with Windows 10 and Android installed and it arrived today.

But I am a newb at this and a bit confused about the hard drive capacity.

When I got to "This PC" in Windows it show under "Devices and drives" 19.0gb free of 32.8gb.

If I go to settings/system/storage it shows 19.0 GB used out of 38.0 GB.

When I boot up in Android and go to settings/storage it shows Total Space 16.53 GB.

None of these capacities come close to the 64 GB that it suppose to have. Have they sent me a 32 GB version instead of the 64GB version ? or does these capacities above seem right for the Teclast 64 GB tablet ?

Hi everybody,

This week, I knew Teclast has a new X98 PRO international version different to the sold one from China. They closed a new International version for EU specially. So, it looks like, they will have 2 international versions. They will launch the new one on Sept 27Th and this new version has not Chinese apks, it has new apks, several new free accesories what I do not know yet, European warranty,…. I work in a media in EU and we received it. They will sell from Spain to EU (www.teclast.es) as I can see on www.teclast.com. Upon my point of view, this step from Teclast is very, very interesting for EU people. I will pay attention to teclast.es in order to see the new presale.

HDMI Output on Lollipop

Hi Guys

I tried posting this in the main teclast air 3G thread but couldn't get much traction there. Hoping someone here may have some advice.

I'm currently on merek's version 4.1 on my Air II and have no complaints. I do have one question though related to the HDMI out. When in windows 8.1, I plug in the cable and it automatically detects the connection and outputs a fullscreen 1080p image to my tv. This is what I would expect. When I plug in the cable for android (mirek190 v4.1) it also detects the presence of the plug but it does not adjust the resolution properly to my tv. What I see is basically a square box in the middle of my tv instead of a full screen 1080p image.

Is there a tweak or file i need to flash to correct this? Should I use the included resolution changer app and if so what settings should I use?

Thanks in advance

I had to take a break my X98 crashed in the update from Win 8 to Win 10... Windows was throwing me a generic error and finally it was the partition tables that were corrupted.

Short story: X98 is fine now I'm finishing the configuration on Win10 (Updates + customizations + Image Backup) so in 2 day I will resume the test. So far it's look good one DSDT modification was crashing completely and the last I have tested was throwing a BSOD with a error message so I know a little bit more were the problem is.

Next step is to make smaller changes on the DSDT to better troubleshot what is causing the crash. :p

I would delete the drivers related to sleeping mode via the "devices manager". I'm pretty sure it is related to drivers/ACPI or even a corrupt registry entry. That's why deleting the drivers should reset completely the registry keys involved. :cool:
