Ok let's see with more recent softwares how it will react, I have attached an archive with newer softwares . :silly:

In the CH341A v1.18.zip you will find the latest 64 bit Serial Driver 11/04/2011, v3.3.2011.11 (you don't need the parallel one).

Off course also Ch341a V1.18 and in the 2 other files v1.23 + v1.24 of the Programmer Software.

Try with those versions and if the driver is not signed just use the Windows "Dev/Test mode" to install it.

Little Tutorial: https://msdn.microsoft.com/en-us/library/windows/hardware/ff553484(v=vs.85).aspx :cowboy:

Let me know what happen now !
[Teclast X98 Air 3G] Mikha777:
You are near, :o you just need to boot from the UEFI Shell now, look here --->

The UEFI shell is the OS that you will use, The USB drive don't boot and it's fine since it only contain the UEFI tool FPT and the BIOS ;)

From there follow the instruction of my previous post. :fingers-crossed:
[Teclast X98 Air 3G] Mikha777:
UEFI OS is the same as "UEFI Shell" but sadly you probably deleted the UEFI partition on the X98 :eek:

First we need to crate a bootable USB key http://www.tomshardware.com/faq/id-1869892/making-bootable-dos-usb-drive.html

Second we need to have FPT utility from Intel for the DOS, I've attached it to the post.

Third We copy the FPT.exe (DOS VERSION) to the USB key.

Fourth Boot your X98 from the USB key and at the prompt it's the usual procedure:

fptw.exe -f Your_Bios.bin

Let is complete 100%

IMPORTANT:

Hold the power button down for 15 seconds to reboot. For some reason it can corrupts the BIOS if you don't do that.

Regards :cool:
[Teclast X98 Air 3G] Mikha777:
Download Win 10 32 bit edition ISO from Microsoft

Copy the ISO file to a USB drive with RUFUS using GPT and Fat32 option

Plug the USB Drive and Fire Up you X98 and press "esc" to go to the boot menu and boot from the USB drive.

Follow the instruction to install Windows. :cool:

If you are not able to reach the Boot menu, just Install again Bios 2.05 or 2.02 with the Dos method, Tutorial here: http://xdaforums.com/showpost.php?p=63133035&postcount=13143 and this time you will be able to go to the boot menu to install Win10 :silly:

If you want to remove the Dual Boot menu after flashing 2.03 or 2.05

HI!

Now after drivers installation looks much better but still not perfect ;p

I choose bios, then I click program and programmer work, but when program bar reach to 100% software don't give me any message - no error, but no success to... Tablet is still dead, connected charger doesn't help...

[Teclast X98 Air 3G] B0IIE:
I think I have the same problem as .oOOo.

I don´t have the UEFI shell option either.

And when I use the way you described to .oOOo. in your last post nothing changes. The behavior is still the same.

I also tried three different usb drives that usuallydont make any problems.
[Teclast X98 Air 3G] nikhtas:
this is the steps to CH341A software. worcks fo me in C6J6.

My english no good

9)With the CH341a software running plug the CH341a into your computer. Make sure that the Chip type is "25 SPI FLASH", the Manufacturer is "WINBOND", and the Name is "W25Q64BV".

10)Press the "Detect" button. It should detect your bios chip. If it reads unknown then you are not hooked up correctly.

11)Press the "Read" button to download what is currently on the bios chip

12)Press the "Save" button to save this locally on your computer. Use a file name like "t01_bad_flash.bin.bak"

13)Press the "Erase" button to erase the chip. This won't take too long.

14)Press the "Blank" button to check that the chip is now blank. This will take a little while. Watch the progress bar at the lower left corner of the window. Continue when it reaches 100%.

15)Press the "Open" button to select the bios dump you wish to write. In my case the file was named "EMBEDDED_OEM_BIOS_DUMP.bin".

16)Press the "Program" to start writing the new bios to the chip. This will take a little while. Again, watch the progress bar and continue when it reaches 100%.

17)Press the "Verify" button to make sure that what's been written on the chip matches the buffer(the bios dump you wrote to the chip).

18)Unplug the CH341a from your computer's usb port, then unclip the test clip
[Teclast X98 Air 3G] .oOOo.:
Nope, I did not. I take really good care of my partitions. :)

With two owners reporting the same problem, it is possible that your tutorial does not work for all versions of this tablet. UEFI Shell never worked for me somehow.
[Teclast X98 Air 3G] Maxx733:
Thank for yours help and answer !

14) I'm got error "The chips are not null"

17) I'm got error "Chip with the contents are in disagreement"
[Teclast X98 Air 3G] Mikha777:
Could you do a

verify

at the end to see if it was flashed correctly ?

Regards :cowboy:

---------- Post added at 06:41 PM ---------- Previous post was at 06:33 PM ----------

It could be your contacts (Clip/Chip) that are bad or for some mysterious reasons for some users flashing under Win 8.1 don't work well so you could have to find/install a computer with Win 7. :eek:

Try it and let us know :silly:

---------- Post added at 06:59 PM ---------- Previous post was at 06:41 PM ----------

[MENTION=3762638]B0IIE[/MENTION] and you seem to have the same problem.

One thing

: X98 has a UEFI firmware and all UEFI tablets/computers have UEFI shell since it's part of the UEFI specification when built/shipped.

The UEFI partition for the shell is very small and will look like this:

Have you tried the DOS method to update the firmware ?

If yes what were (exactly) the results ? :angel:

Regards :)
[Teclast X98 Air 3G] billbmsn:
Sorry, deleted....
[Teclast X98 Air 3G] .oOOo.:
Yes, I checked your instructions because B0IIE reported having problems.

Your partitions differ a lot from mine. I have a 4.69 GB recovery partition. Did you reinstall your X98? That could explain why things work for you and not for me.

I'm not trying to update my BIOS. I was just checking your instructions to help [MENTION=3762638]B0IIE[/MENTION]. I will check this second solution if he gets stuck again. It would be great if there is a solution that works for everyone.

[Teclast X98 Air 3G] Maxx733:
Question to me ?

Win 7 home premium 64x
[Teclast X98 Air 3G] air ll 64gb hg9m owner:
so.in summary.

you tried win8.1 64bit.

then you tried win7 64bit.

try a 32bit operating system. everything on the tablet is 32bit originally i think. try that and report back.
[Teclast X98 Air 3G] B0IIE:
The DOS version didn´t work for me either. I can´t tell you much of a result as nothing happens, but a short blink after selecting the usb stick to boot from. Its the same result either trying the rufus way or the DOS way. I cant boot into the DOS prompt.

I do have the efi partition but its only 64 MB big.

I did Intall Mireks Rom 5.0 and a clean Windows 10.

When installing Windows 10 I was able to create a bootable USB drive with rufus and the windows.iso.

I hope this info will help you to help me better. A big thanks by the way!
[Teclast X98 Air 3G] withoutme5:
I can't boot the mirek v5 roms.. doen's boot, get dark screen all the time after choosing android.

I try 3 times, different downloads and roms (light and normal)

Anybody knows what happen?
[Teclast X98 Air 3G] Mikha777:
Try with this even newer driver attached but I doubt it will work but maybe... :rolleyes:

If it did not work I would try with Windows 7

32 bit

since it's the most compatible platform for the CH341.

Give it a try and tell me the results after. :good:

If you don't have a computer with Win 7 32 bit available to you just use a PE 32 bit version it will be fine for flashing: http://tinyurl.com/qzn34vw :angel:

[Teclast X98 Air 3G] Mikha777:
Hummm it's strange... :eek:

To recapitulate:

You are able to enter in the "BIOS" screen with the ESC key to select the boot device BUT you don't see any option for UEFI.

If I recall correctly you see your USB drive in the device to choose but nothing boot.

If the hardware/Firmware is fine you must be able to boot with a USB drive formatted in GPT/FAT32 with a valid Boot ISO.

Double check that RUFUS is sett on GPT and FAT32 and that the ISO image is VALID, try at least on 2-3 different USB drive in case of incompatibility with one specific drive.
[Teclast X98 Air 3G] B0IIE:
Your recapitulation is correct.

I'll use the usb drive with which I managed to install Win 10 the next time.

But what do you mean a valid ISO file?

As I wrote before, I don't have an ISO file to work with rufus.

Could you upload one?
[Teclast X98 Air 3G] steelicon:
Hi! I just want to share my experience with Android 5.0 and Windows 10 Home on this device.

In Android 5.0 booting takes about 140 seconds (2 minutes 20 seconds) to reach the lockscreen from cold boot.

In Windows 10 Home booting takes about 40 seconds to reach the lockscreen from cold boot.

This is with both Operating Systems using multiple user accounts (3 user accounts).

Android 5.0 has 1 user with 4.83Gb user installed apps, another 1.43Gb installed apps and finally 3.85Gb installed apps. Most user downloaded apps are linked to SD using Link2SD.

Windows 10 Home has only a few user installed apps.

Is this normal? Any ideas? Thanks in advance! :)
[Teclast X98 Air 3G] Perfectdevil:
No this isn't normal

Are you on stock Android 5.0 or mirek v4? You need to check your Android settings or if there's an app that make your booting takes this long.are you using xposed.RAM manager apps...give more info on what kind of apps you use so we can help

I use similar configuration of mirek v4 5.0 + win 10 and android boot less than 30 seconds

[Teclast X98 Air 3G] Lordof9:
Yay,

a new day a new strange behavior of my X98 3G. Now it takes me about a minute to get to the dual boot screen. I push the button and a black screens with a little "9C" appears for about a minute. In the past i pushed the button and 2-5 seconds later the dual boot screen appears. Same thing with the charging screen.
[Teclast X98 Air 3G] Maxx733:
Ok I install windows 7 ultimate 32bit and have same error !!

"Chip with the contents are in disagreement "

Btw I use CH341A v1.18 because v1.23 and v1.24 need licence code .... Maybe its the reason of fail ?
[Teclast X98 Air 3G] Mikha777:
CH341A v1.18 work fine the other versions are in the archive provided just to showcase them for users that flash lot of hardwares ;)

It's very strange, at this point I would try to buy a "blank chip" to test it with the programmer to see if the same thing happen,

if the same thing happen lot of chance the programmer have a problem but if it's work fine with the "blank chip" it mean the problem is on the X98 itself.

So the next thing to try would be to remove the chip from the X98 board and install the new to test it. If it did not work with the new chip programmed the problem will be somewhere on the board of the X98 and at this point sadly I can't really help you.

Let me know the results ! :cowboy:
[Teclast X98 Air 3G] B0IIE:
It didn´t work with this USB drive either.

So it must be this ISO file you are talking about wich I don´t have.
[Teclast X98 Air 3G] Mikha777:
Here's the link of small WinPE ISO image from Based on Windows 7 with some utilities I use to repair computers. :angel:

https://mega.nz/#!opByBBSZ!MRn8OemEbFWKOeK388SNspBJ4rDTMZxLzO_6st1jeLY

It will bring you to a Desktop but there is no Original "Windows Explorer" but there is a Files Explorer and you don't have a "start menu"

It's very easy to use you just right click with the mouse and the main menu is there:

NB: You will need to copy the ISO file on the USB Drive with RUFUS, the setting will be "MBR for BIOS & UEFI" + FAT32 and from there the USB drive must boot after you select it in the BIOS menu of the X98. ;)

If it did not boot (try at least 2 different USB drive) Copy again the ISO with RUFUS but use MBR for UEFI & FAT/".... again if it don'T work try a last time with GPT & FAT32.

From there we will be able to have more informations on how your X98 is configured with the utilities. :cowboy:
[Teclast X98 Air 3G] Maxx733:
I must assembly new blank chip to tablet to test ?
[Teclast X98 Air 3G] .oOOo.:
Same results here. The tablet does not show the USB stick as bootable and UEFI boot only flashes the screen.

I'm a bit confused about these instructions. As far as I can see, the X98 does not support legacy boot.

[MENTION=3986785]Mikha777[/MENTION] What results did you get when you tried to boot your tablet with a DOS formatted USB stick?
[Teclast X98 Air 3G] Franxooiis:
I'm looking for ways to install Ubuntu on dual or third boot. I reduce the windows partition and boot on a willy usb pendisk. The live system reconise partitions only from /dev/mmcblk0p0 to /dev/mmcblk0p7. I try to run the install with /dev/mmcblk0p19 but an error appear, "can't access to this device."

Is it possible to erase all the partitions and move android at the end of the disk ? What partitions can I modify without bricking the tablet ?
[Teclast X98 Air 3G] Mikha777:
No, just begun programming it outside directly on the programmer socket and test if what is flashed is correct with the VERIFY function from the program. :cool:

---------- Post added at 10:50 PM ---------- Previous post was at 10:25 PM ----------

Your right, Sorry

it was my mistake

, I was stuck in a old "thought pattern" with the DOS/BIOS and your question made me think of that. :p

DOS don't work with UEFI at all

, forget what I said about DOS, I was just wrong and was stuck in a old "thought pattern" from BIOS. I read a lot about UEFI in the last weeks to understand how it work and forgot about it :P

That's why when you update through Android terminal you use 2 computers one in DOS mode and the tablet in "terminal mode".

So the answer to your question:

What I used to successful boot with X98 ?

- The Windows 10 32bit ISO burned with RUFUS GPT/FAT 32 = Success

- The WinPE (Based on Win7) diagnostic USB Boot Drive I've done https://mega.nz/#!opByBBSZ!MRn8OemEbFWKOeK388SNspBJ4rDTMZxLzO_6st1jeLY = Success (ISO copied with MBR/Fat32 MBR can work sometime but I suspect it will work also with GPT/FAT32)

From the WinPE we are able to run almost everything since there is a command prompt so I suspect we could even use the DOS command to flash the X98 firmware but I've not tested since my UEFI partition was there but it should work in theory.

Again I apologize for my misleading statements about DOS booting in UEFI mode it's IMPOSSIBLE..... question bring me the fact clear in my mind tha'ts the main reason I've made a WinPE USB drive to access dos command and other utilities when Windoz was corrupt on my X98 .

So give a try to the WinPE ISO since I know it work since I used it a lot ;)

---------- Post added at 11:00 PM ---------- Previous post was at 10:50 PM ----------

With UEFI firmware it's almost impossible to do it and have the tablet to function properly http://techcat.ca/threads/onda-v975...-mint-linux-on-intel-atom-bay-trail-tablet.8/ so having Linux booting from the tablet would be a miracle even more with a

real dual boot

According www jfwhome com/2014/03/07/perfect-ubuntu-or-other-linux-on-the-asus-transformer-book-t100/ we can build our own EFI 32bits for boot. It hope I can end to grub when I choose Windows in the teclast os menu.
[Teclast X98 Air 3G] B0IIE:
I was able to boot Into your WinPE with GPT and FAT32. I didnt have the same colours as you have in your screenshot but I think that doesn´t matter. From there I did nothing else as I wanted to reasure the next steps and because the battery was under 30%.

So from WinPE I´ll start a dos command and use

fptw.exe -f Your_Bios.bin

Right?

[Teclast X98 Air 3G] Estiui:
Ah ok, we agree then. Thanks! :)
[Teclast X98 Air 3G] keepfishes:
I'm actually doing that, but everything looks very big on desktop, and everything else on Metro looks very small...

And I think it would at least give you a 1 hour battery boost. For me I lowered it to 1440x900 and to me, that's the best tradeoff between everything becoming too big for the screen and trying to go as low as I can.

How much battery do you guys lose per hour when the tablet is in standby mode? Mine is 2% which to me is quite a lot... I've resorted to changing my power button to shutdown instead of sleep now... Takes 15 secs to boot up so it's not that long anyway...
[Teclast X98 Air 3G] SUMMERBREEZE:
I SEE, I just thought it was tested and confirmed that it is working.. I understand polish well but not yet perfect, so its my bad..

Well I see that battery usage when in standby is also quite significant. I don't know how it was on android because I've moved to Windows really fast ;)

But when I compare it to iPAD then the difference is really big, you think that this is windows issue or hardware?
[Teclast X98 Air 3G] BoORDeL:
I was on windows from the first day.

I installedcustom windows 8.1 PRO on c6j6.

i hadn't any issues except for 48 Hz video refresh.

The system was stable and fluid.

Than the boss (read wife) decided that ANDROID was better for evry day use (:|) so i had to reinstall ANDROID (the light version).

The tablet is even more fluid and battery is long lasting compared to windows idle performance.

I have to admit that android (light rom) is significally better than windows for this tablet (at least more optimized).

Just my experience with this product.

[Teclast X98 Air 3G] SUMMERBREEZE:
thanks for the review.. but did you also some do additional settings or tricks on that lite rom? i mean, did you still uninstall some apps or for example changed the launcher etc ? i am also now between android and windows.. cos for me, my 3G sim card is very important. I travel a lot and i need 3G internet with me.. as i could see, windows is very problematic with 3g and just for 3g, i cant buy a 3g usb stick for a tablet which already a 3g simcard slot.. :rolleyes:
[Teclast X98 Air 3G] keepfishes:
Glad to know that I'm not the only one getting this problem. I believe it's an issue with either BIOS or Windows or the drivers, and not hardware, since other tablets like the Surface, Lenovo, ASUS users also report excessive drain on connected standby. The difference between them and us is that they have manufacturer support, all they needed to do was update their drivers or flash a new BIOS and subsequently no more problems... For us here, it's a different story, so until today I'm still trying to figure out...

What I've found particularly useful is the "powercfg /sleepstudy" and "powercfg /batteryreport" commands which helps to analyse battery drain... But until now I still can't figure out what it is.
[Teclast X98 Air 3G] SUMMERBREEZE:

For guys in Poland:

3G works OK in Windows on most cards (Plus and Orange tested) but AERO2 gives "can not connect". I can enter the proper APN name (darmowy) but it doesn't help.
