Anyone noticed a strange boot behaviour when charging the tab? Looks like it only boots into Android for me.
[Teclast X98 Air 3G] thehobit:
Installing windows 10

I just installed win 10 preview release (downloaded free from MS site), over previous win 8.1.

Installation was quite smooth, I used the same drivers as for Win 8.1 in the first page (x86).

It has some visual improvements which are more adapted to tablets. Office preview can also be downloaded for free from the store.

Although MS is still fixing bugs and improving the system, it is running quite smoothly so far, possibly slightly better that win 8.1. I will test the battery drain issue soon.

Nevertheless, in my view, Microsoft did not go the extra mile to adapt system to tablets in a proper way.

My benchmark is the fact that mouse is still essential, especially in the windows legacy mode, which can’t be avoided. The pity is that the high resolution of the tablet is actually turning against it in that aspect, by making everything smaller. There is a list on other shortfalls (keyboard issues), yes I assume everyone is familiar of it already.

I still recommend the upgrade to the adventurous ones. Windows, with all the limitations does serve several purposes, and for whatever it doesn’t, there is always Android :)
[Teclast X98 Air 3G] aab44:
Dear thehobit,

could you please explain to me how to update my Teclast X98 Air 3G to windows 10.
[Teclast X98 Air 3G] thehobit:
I'm not sure about update since I did a clean install deleting and recreating the windows partition.

However, there is an "update option" (I used the custom install), which I believe will upgrade the existing 8.1 system. Best is to refer to MS release notes.

From past experience, upgrades do not always run smooth (i read that 8.0 to 8.1 was problematic in some aspects), especially while this is still a preview version.

How do you adjust the thermal values?
[Teclast X98 Air 3G] sauliusz:
I thought that MS fixed scaling issue in Win10. Isn't there option to increase scaling to 300% or more ?
[Teclast X98 Air 3G] thehobit:
There is a scaling option up to 300%, yet it serves the prose to a limited extent.

It does not look native and its limited in legacy mode.

This is the example for "jack of all trades master of none"
[Teclast X98 Air 3G] sauliusz:
Yeah my bad, i googled and it seems that i misunderstood something, too bad MS

BTW has anybody else received their X98 with 64 GB? How are your SSD speeds?
[Teclast X98 Air 3G] WeaponX_BCN:
I would like to apologize because my English is not so good.

I just got a Teclast X98 Air 3g C8J7 ANDROID American Megatrends BIOS:

Core version 5.008

Compliancy UEFI 2.3; PI 1.2

Project 3G068i version 1.01 x64

GOP INFORMATION

Intel (R) GOP Driver [02/07/1008]

TXE INFORMATION

Sec RC Version 00.05.00.00

TXE FW Version 01.01.01.1120

As much as I touched options in the BIOS profit not start the Windows USB pen for installation DUAL.

Does anyone can tell me if this is possible starting DUAL BIOS or if I have to change the BIOS on the other ???

(The vol + POWER combination does not work)

Help, please!
[Teclast X98 Air 3G] xusso:
If the combination doesn't work, then there's only one OS installed, the C8J7 is supposed to be single OS.

I would suggest that you start with the first and second posts of this thread if you want Dual Boot.

Good luck!
[Teclast X98 Air 3G] WeaponX_BCN:
Si: only comes with Android. My question is whether this BIOS can not install Windows with him to take DUAL.

And if the first post DUAL BIOS supports.

I don't own this tablet, yet anyways, but scaling in Windows 8.1 goes up to 500% if you choose the custom option. The programs that don't scale well get a fuzzy font to them but to me its still useable.

Here they both are, renamed to txt

A note for beginners fiddling with these files:

Always make a backup of files you are changing :D

Root needed

Always use a plain text editor

If you want to copy new file version to a system folder:

use a new name (like .txt in this case), copy this file, check the rights of the file you want to overwrite (often rw-r--r-- or 644) and apply these to the new version, then rename the file to the one you need (.xml in this case).

I am a fan of total commander for stuff like this, has all the options you need.

The solution to the non working touch in Android may have been on this forum all along in the rar is a apk file that might be able to fix the controller but I can't get it to work it keeps saying "The driver mobile devices used is not support the Function!"

Can somebody check if they have a file with gt in the name in the /proc/ folder and if they do upload it (this is a configuration file for the touch controller)

[Teclast X98 Air 3G] quocminhbvi:
I noted that this is in 1st post but it is not quite clear (at least to me). Can you elaborate the steps. Thanks.

If you haven't Teclast OTA app you can download it from here: Teclast update tool

If you want can find the apk attached to this post (fastmode.apk).

If you don't want use apk, use adb shell and then su to become root.Then launch these commands:

Code:

echo 400 >/sys/devices/pci0000:00/0000:00:02.0/drm/card0/gt_min_freq_mhz

echo 400 >/sys/devices/pci0000:00/0000:00:02.0/drm/card0/gt_max_freq_mhz

If you want a persistent fix, also after reboot you can create new file install-recovery-2.sh file and put it in ./etc folder with these istructions:

Code:

#!/system/bin/sh

echo 400 >/sys/class/drm/card0/gt_min_freq_mhz

echo 400 >/sys/class/drm/card0/gt_max_freq_mhz

Remember remount /system as rw and chmod this neely created file to 755. You can then execute it or restart to have it automatically started.

[Teclast X98 Air 3G] iPWNtehNOOB:
Just placed an order for an Air II to give it a try. I was a backer of Console OS when I owned my Dell Venue 8 Pro, but ended up selling it before the Console OS Android ROM was released as the screen was too small for Windows.

I've got a couple of questions if you guys wouldn't mind answering them:

1) Which ROM provides the most AOSP or "Nexus" feel?

2) Which ROM is the smoothest? Don't care so much for gaming performance, but I'd like smooth navigation through menus.

3) I see people saying you can install Windows 10 preview on it. Do all drivers work? Given the drivers are similar if not the same as for Windows 7, could I install W7 on it if I was so inclined?

4) How much space is available on the Windows partition out of the box, with Android installed?

Just received yesterday...no freeze

Hy,

Yesterday i have received from 8th Jan'15 sale. C9J8, bios 1.03. i have just root it with i root. and installed both GTA san andreas and real racing 3. I was keeping an eye on the thread from past one month and saw many people are complaining about freezing....but truly i have not seen any freeze in either of these games on android. However i have received few thermal event message.. any one just tell me how to install mirek rom as my bios is 1.03 and version is c9j8 .....BTW i hve tried following hendricson video as well as first OP to install dual boot bios of c6j6...but in OP is says install bios first on android and then on windows but hendrison video shows he first install on windows then on android.....i have tried on android first and its going on and on and on ...i have to cancel the update.i am sorry for bad english ...but should i install mirek rom or not cause everything is working fine...i even has not installed fastmode.apk
[Teclast X98 Air 3G] HDtracer:
Hi, apart from the launcher the tablet pretty much runs stock Android, so I guess use Google launcher and it would pretty much be stock.

I use the stock Teclast rom with Nova launcher, remove the chinese apps manually and use xposed framwork and gravitybox for any customization that I want.

I'm not a much of a fan of deodexed roms, but all the roms here run pretty smoothly.

Sorry cant help with windows questions (I hate windows on tablets haha)

The fix for the thermal message is on page 616 I think.

Rom wise see above. Lots of options and they all run good.
[Teclast X98 Air 3G] ruleonyourself:
i know roms are there but the thread has been outnumbered with posts and my version is c9j8 and all the method and bios is available for c6j6 (stable) mirek has posted c9j8 but someone has written that it is unstable......
[Teclast X98 Air 3G] HDtracer:
Hi, unless you are trying to install dual boot, the bios on the tablet is fine.

If his android version for your tablet is unstable and you are rooted, just clean the stock Rom of Chinese apps and use whatever launcher you fancy.

---------- Post added at 12:58 PM ---------- Previous post was at 12:41 PM ----------

What happens if I didn't? and how do I then fix it? It seems I can't change launcher now, I assume that is the result of deleting tUI first?

---------- Post added at 01:18 PM ---------- Previous post was at 12:58 PM ----------

No, don't worry I think I am ok. I couldn't install Google Now Launcher (because the button I needed to press to 'clear defaults' was greyed out) but I could install Nova and that seemed to straighten it all out. Thanks!

Hey all,

I'm using the device with dualboot-bios, but windows only.

But I've two problems:

1. When I put the device into sleep-mode, the device freezes and gets warm. I've to reset to get it on again. Is there a solution for this?

2. Sometimes the device just hangs - i doesn't matter what I'm dooing, but the screen freezes and I can't do anything but reset the device.

Would be nice if at least the fist problem can be solved :)

Thanks!

Hi, I've been using the tablet for Windows only but this weekend I was bored so I proceed to dual boot.

I only used android the very first days I had the tablet because I bought it specially for Windows, so I couldn't test it very much.

Now I was setting up android and I have realised mi MicroSD card doesn't work on Android, but works perfectly on Windows.

The file system is exFAT, I know that is the problem, but on my Xperia Z the MicroSD works fine so what happens? I have googled but the only thing I found is the Paragon app but it says exFAT is only supported for OEMs (?) and some XDA about the same problem in some smartphones, but I tried that and doesn't work.

I'm using mirek190 v3.1 ROM so I don't know if this problem is only for this ROM but I think that isn't what is happening here.

Thanks everyone, this topic is really helpful.
[Teclast X98 Air 3G] mirek190:
Teclast on android not handle extFat .

You have to convert or format your card to ntfs or fat32.

ONLY NTFS and FAT32 .

iPad Air Vs X98 Air 3G (Screen and physical comparison): https://www.youtube.com/watch?v=2EWsfZGdKVg

Would it surprise you to know that the Windows only 48hz bios allows the screen to be even brighter than the Apple iPad Air..... Yep it's true :) Why I like that bios even if its only 48hz.

[Teclast X98 Air 3G] iPWNtehNOOB:
From what I've read, it seems Hackintosh projects dropped support for Atom CPUs a long time ago, so you'd be hard pressed to get any recent OS X to boot. If you did manage to get a version to boot though, you'd likely encounter zero support for WiFi as these use a proprietary chipset, combined with the fact that OS X wireless chipset support is already very limited. Your best bet would be a virtual machine, and even that wouldn't be very nice.

As for Windows 8.1 + 10 dualboot, I haven't received my device yet to play around with the BIOS, but I would imagine this is probably possible. I know others have managed to get Windows 10 working on it fine, but I'm not sure how many boot options the boot menu can accommodate, or if it will even allow two Windows installations for that matter.

---------- Post added at 11:50 AM ---------- Previous post was at 11:49 AM ----------

I dropped a comment on one of your videos, I'm wondering if you can recommend a decent case for this unit? I don't care much for an inbuilt keyboard, though tri-fold and smart wake features would be nice. Also, are ROMS for this device interchangeable with the X98 Air II?
[Teclast X98 Air 3G] Hendrickson:
I'm not much help on cases sorry as I tend to not use them and just an iPad air sleeve, the cases I did try did not fit without having to cut out parts for the buttons which are on the wrong side to the iPad Air. Ali express and others do sell X98 specific cases that do fit correctly.

Yes Air II roms work on the Air 3G, but you'll be missing the phone launcher / dialler.
[Teclast X98 Air 3G] iPWNtehNOOB:
Thanks for that, I'll probably just end up with a sleeve too.

USB or SD Card boot, with dual boot BIOS?

Hey,

Forgive me if I've missed it in this thread, I have attempted to read all the way through it.

Is there a way to boot from a removable device, SD or USB, on the Air 3Gs with dual boot bios? I didn't realize this was an issue until after I'd ordered my 64GB (C8J6).

I've been, fruitlessly, attempting to get the Windows 8 boot loader to boot from USB (and SD), with no success. I've tried both easyBCD and easyEFI to modify the boot options, and again, no luck.

My eventual goal, if the drivers are there, was to get triple boot Android, Windows & Linux. But secondarily I'm a bit concerned about not being able to easily do a boot to USB reinstall of windows should something go south.
[Teclast X98 Air 3G] thehobit:
If no Android and clean install, I assume yes. Note that you may not have enough disk capacity to install to 2 systems (about 10GB each)

Unless you have a special reason, I would keep one system only.

Hi

Does anyone know where can I find a case for Teclast x98 air 3g with a keyboard that includes a touchpad?

I fond few keyboards, but none of it, is really holding the tablet.

I'm adding a picture of a nice keyboard, but it doesn't really hold the tablet, it is just lying on it.

Root breaks Dual Boot??

Hi,

This is sort of a silly question really but I just really want to be 100% sure.

I was just wondering if I boot into Android (I have the dual boot version) and root it with the VRoot program, will that prevent access to Windows via dual boot? Will I still be able to dual boot to windows and (rooted) android like normal?

Will the program just root the android version and leave windows alone?

Thanks guys! :highfive:
[Teclast X98 Air 3G] ImJamIN:
the full feature bios are present only in the single boot version. Android or windows. Choose one and flash it

If you work on android you are changing only android. If you work on windows you are changing only windows (be aware from partition).

So if you root your android, the bios still remain the same because you aren't working on bios. OK ?

Well you'll be limited to 48 FPS max using vsync and it might not be as smooth for some, possible flicker?, But I see no difference and it might save battery, on my Dell Venue 11 Pro the intel driver would reduce the refresh rate to 48hz to save battery.
