Please reply it is emergency

Dear All,

I have serious problem with my TECLASTX98 AIR 3G (C9J8) 32GB. On the android version everything works perfect I have no problem. When I go to Windows 8.1 I have problems. I tried to free up more space to install windows 10 and searching on the internet I read that deleting WINSXS(from C:/Windows) you will free up alot of space. So i tried to delete that and failed. then I went through few steps which I do not remember exactly but I end up deleting from the System Properties > Advanced > User variables for USER (ALL!!!), and System Variables (ALL).

Now I cannot open System Properties, a lot images from applications are missing and I see a blank square instead, and the most important I cannot make a recovery. Everytime I enter the safe mode, or the advanced mode I get few chinese words and I cannot make a recovery!!!!

You do nothing wrong, HG9M in an

Android only Tablet

. :p

But if you flash the Firmware to 2.02-2.05 you will have the DualBoot and be able to install Windows 10 (32bit) :cyclops:

Fingers Crossed

Hi Mikha,

Tried AfuWin last night I tried the efi versions 32 & 64 bit neither worked the 32 bit 1A32 image trype problem and the 64 bit version kept saying it could not read programme. As for the programmers one can only hope! However just in case I have ordered a replacement tPad should be here next week. worst comes to the worst I will clone it. Once again thanks for all your help and advice I will keep trying various methods until the programmer arrives also ordered some Winbond chips to practice on. Gary
[Teclast X98 Air 3G] Mikha777:
At this point the only thing you have to do is to reinstall Windows 8.1 or Windows 10 (Your Choice) from a USB drive.

https://www.microsoft.com/fr-ca/software-download/windows10 Download the 32bit Version of Windows.

If there is not enough space to install Windows you will have to delete the Windows Partition (Only the Windows Partition). :cowboy:

Argh ^^

Now I did a full wipe out to install Android again, because it has only 17gb space....

And I looked up the model numbers:

The HG9M is Dual Boot!!!! No Android only... ^^

Now I deleted Windows without saving the key :P

The reason, why there wasnt a dual boot menu is:

The first time it can be, that you need to turn on the tablet by pressing Vol+ and On!! Then the Dualboot menu shows up.

Now I have to think how to regain Windows 8 and the key :D

Maybe I will stay at Android only, but there is another problem:

I used the partition.tbl from Mireks Android 5 Rom for Android only, so I should now have the full storage of 64gb located to Android.

But still: only 17gb space under Android... :/

hi! I have installed the BIOS but it is all in Chinese! I do not know if it's been successful! how can I be sure?
[Teclast X98 Air 3G] supercowz:
Why not change Chinese to English language or full English win8.1 pro with Rufus.... Anyway...

Enter the bios and check if is 64bit then is OK...

Same as this
[Teclast X98 Air 3G] soudara:
i'm sure at 90% flash new bios can not fix 48hz probleme , the probleme on c6j6 it's edid eeprom on lcd panel have bad information , intel hd drivers can not override edid infos like amd or nvdia gpu and we can not use custom edid infos on monitor drivers , i think not 48hz probleme on ubuntu or android because you can override edid information but not on windows with intel hd graphic driver , or need to reflash edid eeprom directly on lcd panel but need to open tablet

60hz working on hdmi output because the edid of your external screen is correct but not on the integrated lcd panel

if you have flashed c8j7 with c6j6 bios and install windows and have 48hz problem probably c8j7 have bad edid information too

teclast know the problem if it's easy to fix , he can fix it but i think it's same problem of lenovo y50 48hz probleme 3 year past not fixed
[Teclast X98 Air 3G] peppemaria:
There is no information about 32/64 bit.. When i press VOL- VOL+ and POWER compare the line " entering dnx mode..." but After 20 seconds the tablet start with windows normally! How i can do? Can i change languages? There is all in chinese! I don't understand anything
[Teclast X98 Air 3G] supercowz:
Not good bios!!

Look :

Change win8.1 to english

I read this Teclast forum topic he said Trial Model Dual Boot OS is C9J7

从外观来看，双系统版和单系统版的A3没有任何区别，唯一区别就是机身背后的编码，双系统版是C9J7，而我手上的单系统版是C6J6.圆润、简洁的外观，超薄的机身也较容易获得大家的接受。

hi Estiui,

there exist an onlineshop where you can pre order dual boot win8.1/ Kitkat X98 Air 3G now. They have written they will ship it in the end of December. (When they do not have any problems). Right now I have ordered the windows version because I think the place is a little limited for 2 OS.
[Teclast X98 Air 3G] SUMMERBREEZE:
you wanted to go back to Android yes? now follow the guide very carefuly and just flash the android ROM from your PC.. the bios looks OK to me..

Can you not enter Fastboot now? turn the tablet off and go to fastboot? doesnt work?

---------- Post added at 05:37 PM ---------- Previous post was at 05:36 PM ----------

mouse probleme!

Hi, this is my first post here :o,

I want to upgrade my c6j6 to 4.4.4 and i preparate all files and install all drivers but when i run "Manufacturing Flash Tool" my usb mouse blocks ,when i close it i have the mouse working again:(i have windows 7 64bit and antivirus+firewall turning off)
[Teclast X98 Air 3G] robusto:
What do you guys think that is the probability of us c8j7 users having a winodws compatible bios? I ordered this tablet with windows in my mind and still have the possibility of disputing.. Love the build quality and the display but quite frankly

I might want to return it I cant use it to its maximum potential... What should I do?
[Teclast X98 Air 3G] SUMMERBREEZE:
so do you have c8j7 device with windows in your hands now? do you have any problem with it? for example screen refresh rate is 48hz or 60 hz?

Can you please do a backup for drivers and also dumt the bios?
[Teclast X98 Air 3G] robusto:
Nope. I have a C8J7 but with android tho.

What I ment is that will it be possible in the future to install Win on this baby?
[Teclast X98 Air 3G] SUMMERBREEZE:
of course it will, all we need now is a bios from preinstalled C8J7..

My X98 is unbricked !

Tonight I re-programmed

successfully

the Firmware of my bricked X98 Air II. :victory::victory::victory:

It's not that's it's hard to do but since there is MANY tutorials, drivers versions, software programmer versions (.exe.) and I lost 2-3 hours to untangle all the informations., it was confusing :eek:

So I will do a simple package/archive with all the software needed with the latest versions, and simple/clear instruction to save time to users who may need to unbrick their X98. :angel:

Personally I've downloaded over 180mb of utilities for the CH341A to use less than 20mb of software.... The balance is just outdated softwares/drivers.

With the right softwares from the beginning it should took less than 45 minutes to do

, the hardest part is to put the clip correctly on the Winbond chip. :p

I charge my x98 overnight and re-install Windows 10 tomorrow, I used Firmware 2.05 Firmware. :cool:
[Teclast X98 Air 3G] danil0:
thank you

is there bios update also in this package ?
[Teclast X98 Air 3G] Mikha777:
Nope just the driver for Win 10 :cowboy:
[Teclast X98 Air 3G] danil0:

Can anyone share pid or MFT setting values for x98 air II 32gb tablet? I didnt find them in techknight tutorials or in first post. Most of the info on web i found is for 3g variant and not air II.
[Teclast X98 Air 3G] Mikha777:
Yes try with the UEFI method :cowboy:

There is no more risk to brick your X98 than with any other methods if you follow the instructions.

You do it from the same computer/tablet so no no cable and No other computers involved :cyclops:

Just

DON'T forget

at the end of the process/flashing to shutdown the tablet by pressing the Power button for 15 seconds ;)

How Flash your BIOS via the UEFI shell:

You connect a USB hub to your tablet and connect a Keyboard to the hub and a USB key with the

BIOS file

+

FPT.efi

command and the

fparts.txt

on the USB Drive.

Important:

To be recognized by the UEFI SHELL BIOS the USB must be formatted with GPT AND in Fat32, the more EZ is to use the RUFUS utility to format the USB drive. So don't forget to format the USB drive before copying the files ;)

You power up the tablet and press "ESC" key to enter in the BIOS.

In the BIOS you go to the Boot selection and choose "UEFI Shell"

You will see a screen like this:

You press any key to have the SHELL prompt (There is not Startup.nsh on tablet it's a generic message in UEFI bios)

You are now in the UEFI shell, it's a littel bit like the old DOS shell.

We now need to know where is the USB drive so you will type "map -r" (Without the quotes)

It will list all the devices available:

You try to find your USB drive, usually you will see "Removable Hardrive" in the name somewhere.

To be sure you have the good device you type at the prompt:

"ls FS1:" (Without the quotes) and press "enter"

It will list the files so if you see the BIOS file and the fpt.efi file you are at the right place if not try another device FS1 FS2 etc...

Once you are in the right device it's EZ:

First we will do a back-up of the BIOS, so Type:

"fpt.efi -D MyOriginalBios.bin" (Without the quotes) and press "enter"

It will do a backup of your bios named "MyOriginalBios.bin" saved on the USB drive.

Now we will Flash the BIOS so type:

"fpt.efi -f MyNewBios.bin" (Without the quotes) and replace MyNewBios with the name of the bios file) and press "enter"

The process will begin you wait few minutes till it end and you should receive a message that the process was successful.

IMPORTANT:

At this point you shutdown the tablet by pressing the Power button for 15 seconds ;)

That's it ! Enjoy ! :laugh:

N.B.:

Link for Flash Programming Tool:

https://mega.nz/#!o4YADKZJ!Q1q3J8wSC9npX1ofrGE3iAwYEMAodREv1v-PhrJIXKI

For the BIOS you can use any BIOS from 1.03 to 2.05

has anyone idea why is this happening?

I tried several drivers with no luck.. my version is HG9N
[Teclast X98 Air 3G] Mikha777:
Usually "error 204" happen cause the transfer of the data from the file to the firmware was not perfect, even if it work fine I would try to flash again with the same procedure to be sure everything is fine.

From what I remind HG9N should not have any problem under Windows, could you check in the device manager under Windows and tell me what you find for the camera especially the front camera...

If

Front camera is recognized as OV2680 instead of GC2235 and throwing a code 10 error in device manager it's because from BIOS 1.07 and higher they don't support the GC2235 Front camera in the DSDT sadly I will

try

to fix it soon in my free time.

The good news is that with Firmware 2.05 there is no more power leak when the X98 is in sleep mode ;) Before 2.02 there was a major drain on the battery in sleep mode. :D

For the Android I can't really help since I only have Windows :p But Firmware 2.05a (like you have) have the same benefit and limitation than Firmware 2.02 but have few less minor bugs. So if you read something about Firmware 2.02 it apply to 2.05 and vice-versa. :cowboy:

Regards :angel:
[Teclast X98 Air 3G] danil0:
thank you for the answer..

yes in device manager the front camera is 2680 not 2235... please try ti fix to...I think this is a major problem...we can not skype anymore:rolleyes:
