Be sure you use the prompt with admin right first.

If it did not work try:

runas /user:administrator cmd.exe

cmd.exe can be any command like fpt.exe ;)

Also I'd like to know if it is Windows itself or the FPT.exe that throw the error. :cyclops:
[Teclast X98 Air 3G] Mikha777:
You can also try the Win version with a GUI AFUWIN, use the 32bit version. :cool:
[Teclast X98 Air 3G] B0IIE:
I´ll try that next.

Here are two screenshots from WinPE when I used cmd as an administrator.

And one from afuwin, also with administrative rights.
[Teclast X98 Air 3G] Mikha777:
Which Firmware Version do you try to flash ? 2.05 2.02 ????

I will look further but it's like if the BIOS you try to flash is not signed ?

This one (2.05) is signed as far as I know: https://mega.nz/#!wgBjEbrI!Bn1HY_iSynNjpzE9Glsp3-5fcip7XfAge8HXhHph9gY :silly:

Try also with the Windows version = AFUWINGUI.exe we could have more information from the GUI ;)

I've attached the latest version :fingers-crossed:
[Teclast X98 Air 3G] B0IIE:
Nothing new. If I use the rom you posted or if I use AFUWINGUI.exe I get " 18 - Error: Unable to start a secure flash session".

Maybe it isn´t possilbe to flah the bios from within WinPE?
[Teclast X98 Air 3G] Mikha777:
Let's try another thing:

afuwin.exe MyBios /GAN

GAN is an undocumented switch to bypass some protection but use the AFUWIN version cause GAN is only in the Win version.

If it did not work I will check if there is something wrong on the PE that prevent the flash from working. :cool:

[Teclast X98 Air 3G] B0IIE:
That worked. Kind off!!

The flashing was successfull. But after I shut it down and held the power button for 15 seconds I can´t boot it anymore.

Nothing happens when I press the power button.

I think that bricked it!!
[Teclast X98 Air 3G] Mikha777:
What version bios you have you flashed ?

At least we know that with /GAN it work from WinPE, I don't think the brick is due to the /GAN option, it more "badluck" than anything else.

Yep with GAN it work most of the time, from what you told it seem bricked (no power) like me you will need a CH341A programmer, I wait patiently for mine... :cyclops:

I paid mine less than $10 with the clips ;)

I received my X98 Air 3G from Gearbest today. It is C5J6 with BIOS 2.05, Win10 and Android 5.0. Android is full of bloatware, but the cams work under Win and Android.

Windows is not activated and the activation failed with error "this product key is beeing used on another PC...". :( I'm going to demand a new key from GB.

The SIM card works under Android, but in Windows the OK button is disabled when I enter the PIN. In the CDC MBIM device properties an information note says "The USB\VID_8087&PID_0911..." requires further installations. What is missing here?

[Teclast X98 Air 3G] Mikha777:
You don't see the icon cause Windows is not installed on your tablet, after installing the dual bios (2.03 or 2.05) you must install Windows. :cowboy:

I'm not sure what kind of error because it's shutingdown in 0.5s. Did I just make building material from tablet?
[Teclast X98 Air 3G] cattolicboy:

This matter was discussed a lot of times in this thread: the X98 is NOT designed to run a 64 bit operating system!

Same thing happened to me with the 2.05b (Bricked) but with 2.05 I was fine. :p

I think I may have used the "first" release that was not "patched" by [MENTION=2198172]mirek190[/MENTION]

They are from the same seller so you I will receive them (clip + programmer) at the same time, the feedback of the seller look good to and the shipping was fast 48 hours after my order. I expect to receive it this week but it's from China so I know it can

SOMETIME

take up 8 weeks but usually it's 2 weeks. ;)

Here's a

complete CH341a tutorial

with softwares to flash the firmware https://mega.nz/#!YgRRXLQJ!T9RefL5mwNnNA90I8AlaolydVLTMPDY2_9Sl06E5PPU Also I've collected on the web almost every CH341 softwares/Drivers version available so if you need other drivers or version I should have it just ask me !

BTW:

Question for [MENTION=2198172]mirek190[/MENTION] : Could you explain me what are the modifications you make to the BIOS/Firmware to prevent them to brick and what is the theory under the modification or why it have to be changed before flashing ?

If I remember correctly it's changing some bytes in the image via Hex editor but I can't find more information on Google about this.

Does the 2.05 bios has any difference with inaccurate battery reading and battery drops like with 2.02?

Any link for working update file...?
[Teclast X98 Air 3G] UK3G:
Hi Andreasph, two things, firstly Gearbest say that they test each device before the ship them, so why did they no pick up on the windows issues before sending the device out. Secondly, I ask this because I am in the process of ordering the same model as yours from them and wanted ti know whether you had any issues with them. As I thought upgrading from 8.1 to 10 and 4.4 to 5 would be too difficult for a novice like me, so going for one already pre-installed should be easier

[Teclast X98 Air 3G] andreasph:
Hi UK3G,

all the functions I've tested so far on my X98 Air 3G work. I didn't install software anyway, because I want not make any change before I get a valid Win 10 license.

In the meantime I've tried to activate Windows by telephone, but MS told me that this key has been activated too often. They regret that they cannot help me. This is a big issue for me, because a Win 10 license would cost me more than half of the tablet price. I'm waiting for an answer from Gearbest after sales support right now. I hope they can solve it. I'll keep you in touch.

As far as you know uefi is an operating system that write / read data and that 2 bits are propably to activate uefi ( install ? ) drivers on the tablet.

[Teclast X98 Air 3G] Mikha777:
It's easy, first install Easus Partition Master Free in the Windows Partition http://www.partition-tool.com/

After post a screenshot of all the partitions on the X98 here and I (or anybody else) will be able to tell you which partition to keep and which to delete.

Once done you resize the Windows partition with the space from deleted partition with Partition Master.

The only part "strange" for me is why downgrade to Windows 8.1, you will have to find a Win 8.1 license and have less function than Win 10 IMO.

In Win 10 you can strip down everything you don't like including Cortana and even replace the start menu. ;)

Wich partitions do we have to keep ? Is that only the EFI and Windows one ?

If I erase all my partition, do the tablet still enter in the bios and is able to boot from USB keys ?
[Teclast X98 Air 3G] Mikha777:
Since my tablet is "bricked" and I wait for the CH341 programmer I don't remember for sure... :p

You have to keep the EFI partition since it did not take lot of space and from there you can do lot of things like upgrading the firmware etc etc... (but it's not mandatory)

For Windows you need to keep the system partition that is in Fat32 to boot and the one in NTFS which is the main partition for Windows.

Just send a screenshot of your partitions with Easeus Patition Master it's free and this way it will be more easy and safe to tell you which ones are important.

Helloy guys,

Ive searched the web, but couldnt read all 1000 Pages of this thread to find an answer. (or is there a possibility to search in this thread for posts with keywords?)

I got my new X98 Air 3G today and followed the instructions by TecKnights Tutorial for flashing the BIOS to 2.02 by usb-cable with Host PC.

Everything worked fine till the flashing process started. I took only 1-2 seconds till it finished.

Now Im not sure, if I sucessfully flashed the Bios.

Here is my question now:

How can I determinate my current bios version? In TecKnights tutorial there is missing this section and the web has no answer for me.

I trid the system information through the regedit command msinfo32, but there I can only see:

BIOS Version/Date: American Megatrends Inc. 5.6.5, 1/16/2015

I fear, if I flash the bios again, I can cause trouble....

So, hopefully you can help me :)
[Teclast X98 Air 3G] dzikk:

Hi andyon2, I have the 3g tablet bought from official Teclast Malaysia. Since you have successfully updated the bios, I'd like to ask you a few things:

- how's the windows battery drain issue? having 3-4% drain on standby currently
[Teclast X98 Air 3G] Spectator_0o:
Why would you want to downgrade your bios? Shouldn't the bios you have gotten with your tablet be 2.05?

Just connect your USB Keyboard with this OTG cable and press ESC on bootup (before entering the OS menue).

Hello,

sadly I have been several months disconnected of this forum, and I came back, searching for news in the first page of this topic, and I haven't found any new information, so it hasn't been updated anymore!!!!

I know it is selfish to ask for a summery of last months, but I cannot read 500 pages :(

Last things I tried was a new BIOS which fixed the Windows Battery drain problem, but Windows still facing the freeze on games. Now I see there is Windows 10 and Android 5 from Mikrek.....

Can someone make a short summary, please? Which are the options for Android and Windows now? Any chance to load those new roms in first page?

I think my BIOS is old already (Project Version tPAD 2.02), and Intel GOP Driver 7.2.1011 for my "old" C8J7 tablet.

Thanks a lot in advance, and if you feel is not fair my request, I understand, don't worry :)

[Teclast X98 Air 3G] UK3G:
i'm waiting for delivery of the this tablet, but with Windows 10 and Android 5 already pre-installed. I've been working my way through the treads but would like to know:- 1) The bios should be 2.05 as its the tablet is coming straight from the factory i'm told. If this is the case, will the dual boot app already be present on the device and if not, how would i install it without going back to version 2.02? (2) If i have to revert back to version 2.02, i've read that i would lose my windows key, would that also apply to the office 365 that comes with it? and finally (3) Its noted that in Android, the device is riddled with bloatware. I plan to flash it with mireks android 5 V5 rom, how simply / difficult is this to do and will i need to root the device first. Thanks
[Teclast X98 Air 3G] fraz0815:
1) dual boot present, no need to change

2) if you flash a new bios the windows key will get overwritten but if you ever have to, you can backup the key before flashing another bios - see teclasts's tutorials

3) simple. two methods: first with MFT described also in teclasts tutorials or with new installers that ship directly with the mireks rom

Hello there, I'm new of this forum, and I am going to write for the firt time as I have a problem (actually I have some) with this great tablet.

I've had the x98 air 3g for 3 months before my brothers broke the touch screen (fortunately LCD are ok).

So I bought a replacement screen for AliExpress. I was aware that there are different connectors, I did not open the tablet before the arrival of the new screen so it was a lottery.

I got a PB97JG1471-R2 connector from AliExpress. Then I took the tablet to a "tablet repair" shop with the new touch screen. They changed the screen (I was not able to unglue the touch screen).

Today I got back my tablet, I turned it on, and it automatically started Android as the last time. I tried the touch screen and everything was ok.

Then some minutes ago, I tried to switch to windows and I noticed that both the dual boot screen and all windows are not ok with the new touch screen: it works but the cursor is in a different position, distant 4 or 5 centimeters from my finger.

So what is going on? Touchscreen perfectly working on Android, and that disaster with windows (and the dual boot menu) ?

What do you think the problem is? I have a wrong connector? In this case, how to discover the right one, considering that the shop does not have the broken one?

Thanks in advance :(
