thanks.. but it was working running a program for 4 hours left on (it was a cold night too not usual warm weather).. and charger plugged in at the time..

hows leaving it on charge solution here?

however I just tried another usb charger 2amps as soon as plugged in come up with same error on screen

if you are correct perhaps their charger is faulty

=== ok you might be right !!! im now getting battery logo for charging..

flipping hell their charger died over night then. think they are switch mode was making a buzzy sound!

thankyou thankyou fingers crossed it will come back

acutally I tried their charger on older tablet and charge light comes on.. very strange.. confusing

perhaps its degraded and not 2.5 amps beats me..

I'm just curious - what app you are using to decompile uefi ?
[Teclast X98 Air 3G] Mikha777:
Only thing I use is IASL (From ACPICA) for the DSDT, the rest is the source.
[Teclast X98 Air 3G] jcinfo:
Nice y wait for this new bios 2.05, for moment possible for have files to add DSDT/ACPI in Windows for my camera work ?
[Teclast X98 Air 3G] valerima:
Big files- over 4GB

NTFS or exfat support

Especially SD card.

Is it somehow solved for our device?

From windows probably it should go...

I was working with Onda and noticed that was not able to copy some bigger mkv movie. Was this option somehow included by Mirek?
[Teclast X98 Air 3G] zenitraM:
I managed to install it. You need also to download the "tools" RAR from the Teclast website (it comes on the link for the chinese Windows 10).

Then you have to follow the steps on the PDF on the chinese part, you can more or less understand it with Google Translator:

- Have two drives (or a drive with two partitions, one FAT for the "tools" and one NTFS for the .wim)

- Put the contents of the folder wimboot (in the tools RAR) in the FAT one

- Put the "images" folder on the NTFS one

- Boot from the FAT one using USB hub + BIOS

It will boot on a command line and automatically find the drive where the "images" are, format the last partitions (the Windows ones) and flash the image, without any interaction. You need a keyboard though to enter to BIOS and exit that command line once the install is done.

After a few reboots and clicks the install is done, it comes activated, on English and Chinese and it seems to be clean.

Also, you can use a single NTFS partition for both "images" and "wimboot", but you need something else to boot the EFI bootloader from the NTFS partition which is not supported by default on the tablet, I used this and it worked fine:

[Teclast X98 Air 3G] joq3:
I have noticed a thing that disturbs me.

When I have the tablet set to 25%, 50% or 75% I notice it tries to dim the screen when the colours change.

Say I am on the desktop, a bright colored background, and open an application that is very dark, I can clearly see that the tablet dims. Not smooth, that's what is annoying, it is jumping down when dimming, like it is flickering.

This looks very bad, especially when watching a video in a dark room. You notice it all the time as the scenes change.

Is this some setting or driver issue in Windows 10?

Have not yet tried if it happens in Android.
[Teclast X98 Air 3G] nodoka256:
sir first thanks for your replay

I already did use MTF ( rom: X98 Air 3G (C9J7) mirek190_v3.1 ) and chose flash-full_with_pattitioning, but when progress about 10% the tablet reboot, usually tablet will entering flashboot mode, BUT now tablet reboot to windows, so the MTF failed.

how can I fix it

Thanks
[Teclast X98 Air 3G] agunghost:
I had the same problem a while ago but it should be easy to get rid off this problem. "Flickering" display is really annoying.

What you need is just change the display setting via INTEL HD Graphic Control Panel (If already install windows 10, make sure you have updated intel graphic adapter).

To access intel graphic control ponel, just right click empty space in desktop (anywhere), Choose Graphics Properties. Then, Choose POWER. Below Display Power Saving Technology, Click DISABLE.

This last step is just to switch of display power saving which cause "flickering" problem.

Hope this will solve your problem.
[Teclast X98 Air 3G] tecknight:
Maxximo,

An install.wim file is a customized, automated installer for Windows.

It allows you to customize an install by including files not included with the stock installer, such as drivers for the specific hardware.

It also allows for pre-configurations of typical install options, so that the install is completely automated. You need only select the .wim file and the install will complete on it's own.

I suspect that Teclast bundled the Windows 10 drivers and pre-configured the install.

This is a good thing, in my opinion.

---------- Post added at 02:31 AM ---------- Previous post was at 02:26 AM ----------

Nodoka,

Could you please post your MFT log of the attempted flash ?

---------- Post added at 03:16 AM ---------- Previous post was at 02:31 AM ----------

I don't know how it went downhill either.

My questions are solely for the protection of the users who are flashing their BIOS and taking a risk of bricking their device.

I want to make sure 2.05 is safe to flash, that it actually came from Teclast as an official release, that it provides something more than 2.02 provides, and if so, what has been changed.

I also want to make sure that multiple people have flashed the 2.05 image and they are not reporting any problems.

For the record, I applaud the effort to develop a BIOS that can support all the cameras present in the different models of Air 2 and Air 3G devices. I hope Mikha is able to succeed in this endeavor, as it will help the entire community.
[Teclast X98 Air 3G] Maxximo88:
Yep ok, this is a good news.

As you know, many users upgrated their tablet from Windows 8.

In my experience, a fresh install of Windows (and Linux OS) could give more reactivity/speed/stability.

So, I just want to write a Guide about it for Teclast community (and italian users).

---------- Post added at 01:04 PM ---------- Previous post was at 12:43 PM ----------

Wow, great!

I will take note about It.

I want to write a Guide. If I have time I will do a video-guide, but I don't have time now..

You can install 2.05 right now (For the link see my previous post) if everything goes fine I will be able to test the DSDT today or tomorrow and right after I will post the the DSDT with complete instruction on how to install it. :cool:
[Teclast X98 Air 3G] valerima:
I am sorry, Mikha777, but

Could you provide information on which devices this new bios was installed and what results did you have?

Any cameras started to work compare with some previous soft?

How many have installed your bios?

How big is a risk to brick the device?

Where improvement was noticed?
[Teclast X98 Air 3G] Mikha777:
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. :cyclops:
[Teclast X98 Air 3G] joq3:
Do you have 2.05 installed? Can you check if it has English OK in the boot selector screen? Because I have seen on a video of new X98 Air that they have OK instead of chinese characters in the OS selector.

Also does it have the english Teclast logo (without chinese characters) when you boot it up?

Hey, just finished uploading both the WINPE and the WIM images for W10 to Mega, here they are:

WIM ("images" folder with the big wim): https://mega.nz/#!Vk10EK6a!GxsGd4tEszyBMfBNn53VEOu3guQJqGtPBeWzYPpsaqs

WINPE (installer for the images): https://mega.nz/#!g4EDhDRI!SfKLjl__B2lMN4zdGCwNBqjugmiHcTJ3UmONtotckUo

Probably the .wim can be splitted into 2GB parts (and the .bat which performs the setup modified to use a .sim instead of a .wim) so no NTFS partition is needed.

Here you can find all the drivers that comes with the last windows 10 teclast relase.

[Teclast X98 Air 3G] nrdmtt:
This are raw data, just extracted from /System32/Driver and /System32/DriverStore

So you can either install a clean version of windows 10 and then update all the drivers manually (one by one..... ye.... i know), or you can create a custom windows 10 install iso with all the driver integrated.

Actually I do not know if there are programs that let you batch install the drivers :good:

Time permitting, I will create a custom windows installation in the week end with all the drivers integrated, starting from windows 10 international version

I have the same problem. Still to understand if it's a windows bug or a driver related problem.

Actually I am using the latest z3700 driver from dell (for win10), but I think the previous version (for win 8.1) was better/with less bugs.

I'd like to have some

"advanced users"

comfortable to have their

Windows Registry modified

The only

risk is to corrupt the Windows registry

and in this case you will have to Press F8 and choose the "use Last Known Good Configuration" option." to start again. Even better just have a recent "Image Backup" of your device is always useful when you "hack" in you computer. :silly:

The "change"

don't involve hardware changes

at this stage but only software change AND Having already

BIOS 2.05 Installed

in your X98 Air.

Send me a message

if you want beta test and later (

today or tonight

) I will send you the instructions via Private Message on how to do the testing. :victory:

N.B.:

Will only pick-up the first 3-4 users that will answer. so don't take it hard if you don't receive an answer. From that point if everything is alright the fix should be released today or tomorrow. Right After Next Week I will begin to see if it's possible to implement the fix in the BIOS directly.

My wifi disables itself occasionally.

I was watching Plex on my C5J6 version last night, with my bluetooth speakers connected to the Teclast and streaming video via Wifi.

That is when the device dropped wifi, went to check and the Wifi-card had disabled itself in Windows. I enabled it, and it connected to internet again, but 5 minutes later it happened again.

What is this? Is it bluetooth that interferes with wifi?

Weird thing is that it worked for 3 hours the day before, streaming video and using the bluetooth speaker.

Please help me out! Why does it disable the network card by itself in Windows!?

Hi,

I have been running Mirek v4.4 for the last couple of months and decided to try Lollipop V5.

Adb and all drivers are installed (and I have tried re-installing them) but when I try the update it will hang immediately after starting Daemon (left it for 30 mins and nothing happens). This problem arises on whatever PC I try (various versions of windows), whatever cable I use to connect and whether or not it is fresh boot of Android. Developer options are on (USB Debugging on).

Any ideas???

joq3,

What is this? Is it bluetooth that interferes with wifi?

Yes, bluetooth does interfere with wifi. A certain degradation in performance is expected, as bluetooth and wifi operate within the same frequency range.

However, I have noticed on my X98, that my wifi slows down dramatically when bluetooth is enabled. My wifi adapter has never disabled itself in Windows, however.

That being said, I am definitely not a fan of the changes to wifi configuration in Windows 10. It is much less intuitive than Windows 8.1.
