[Teclast X98 Air 3G] HDtracer:
I dont have the tablet with me atm but I do seem to have a lot more system partition left (500mb more) compared to 4.4.2.

Would it be possible to run Windows from the SD card do you think?

Because looking into the future with my crystal ball I can already see the "I have run out or memory" posts :o

Don't reboot windows 8 !! And try to reflash

Open cmd command with admin right ... Then try flash again

C6J6, Win10 installed, flash for dualboot

First of all, thanks for everyone here !

I read for hours the last tens of pages, to be sure I dare to make my move to dual boot.

Not too familiar with these, but I have done something before. And I normally can use Google.

So, no step to step (and I mean really every step, not just "flash from windows" ) instructions from the forum yet, since I need those.

After hours of reading, some Googling, copying the "dualboot bios tested C6J6 and C8J72" files to tablet folder C:\Flash_BIOS, renaming .bat file from Chinese to "known" letters, flash.bat

Running command prompt with administrator rights, typing "cd C:\Flash_BIOS".

Then giving command "flash", and crossed my hands.

Lines scrolling in the window, some mystical characters, and finally ">pause, Press any key to continue . . . "

-Closed Command Prompt window, clicked shut down, and restarted from power button.

-Tabled started in BIOS, and saved the settings and exited (not really changed anything), BIOS screen opened again.

-Shut down the tabled pressing long time the power button.

-Started tablet with long pressing of power button.

-Boot menu came there , of course only Win option there, choose it and Win10 started just as before.

-60Hz refresh rate, camera upside down. So all was good :) Some work to do tomorrow.

-Soon also Android and also new Windows installation if no recovery (Acronis etc.) works

Again, Thanks.
[Teclast X98 Air 3G] micky1067:
Sure you can not see what I see.. Will be nice.. ;)

I have the Stock ROM Android on C6J6 Tablet and is rooted. I have broken now the flashing. Is ok.

I can start all apps. On my Tablet was no IFWIUpdater APK. So i get one from this file: http://fs1.d-h.st/download/00149/7OC/X98 Air 3G Android4.4.4.rar

Is Version 1.0 . And then I start to flash it like Post #1591 from this thread.

Is it not the right way ?

Thanks ... so much for your help

I will write what I did in points:

1. downloaded Windows 8.1 PRO 32bit ISO from 1st page

2. made bootable pendrive by rufus. Clear ISO file, without integrating drivers etc. GPT and FAT32

3. installation launched, but i got error: "Windows cannot install required files. Make sure all files required for installation are available and restart the installation"

What I did wrong?
[Teclast X98 Air 3G] micky1067:
Sorry for my mistakes.... But I am new in this way. Only flashed Phones. Now the Tablet is special for me.

BTW, maybe we could reduce the Android data partition do 4GB and disable SD emulation?

If we do it, the default place for downloading and ringtones + others will be external SD Card, as in older Android phones ;)
[Teclast X98 Air 3G] supercowz:
how much ?

on 11.11 event c6j6 or c8j7 android only was arround 180$ with free shipping, allway order free post shipping since dhl or fedex allways charge me 40-50€ fee/custom, no fee on regular post ...
[Teclast X98 Air 3G] ImJamIN:
I should wish to give more space to android because windows has already 6gb of free space. If you want to install some game you can install to sd card.

While for android is more important /system and /data partition and less /cache and /logs . So if we can optimized android partitions to have more space to use to specific partitions, it should be more smooth and usable. IMHO

[Teclast X98 Air 3G] Hendrickson:
Supercowz, your the man here on this dual boot topic now. You have my thanks! I have thanked you as much as I can. I will try dual boot on my Air II tonight if I can. Hopefully it's not going to brick. I will update this in the Air II forum.

I agree, it seems some hardware revisions took place. I know that my C6J6 touch screen is HORRID compared to the newer hardware used in the Air II I have. The touch lag it gives makes windows seem like its stuttering, but use a mouse to scroll and it's smooth. Proof that it is the touch screen.

I recommend people stay clear of the C6J6, I assumed it was the android rom lagging, but on after getting the Air II for a friend I found out it's not. Ask your seller on Aliexpress for the latest revision, not old stock!

should i install it and then flash dualboot ? or just like this i should flash the dual boot :confused:
[Teclast X98 Air 3G] supercowz:
Flash dual boot straight .... Very easy start updaterIFWI (blue circle) apk do you see it on your tablet ?

Did you install all the driver first ?? On your PC for manufacture tools ??

iSocUSB-Driver-Setup-xxxexe: At some point during the installation, you will know that you have to connect the X98 with USB cable to the computer to install the NAND drivers. H connection is necessary otherwise you can install to see and shape the NAND memory of tablet.

IntelAndroidDrvSetupx.xxexe: We run this installer as an administrator with the tablet plugged in USB. This will install the ADB driver Intel, which appears in the Device Manager (Device Manager) for Windows. (See the picture Figure_1)

ManufacturingFlashTool_Setup_x.xxexe: This tool is used in the final planning "name" (branding) of the tablet and install the fastboot kernel. Install with administrator rights on the proposed application folder (hold down the name of the file for the next step).

- Upon completion of the installation of the Intel Manufacturing Tool, copy the file "CUSTOM_CONFIG.INI" into the folder that the tool was installed (the default is C: \ Program Files \ Intel \ Manufacturing Flash Tool).
[Teclast X98 Air 3G] SUMMERBREEZE:

Great work guys. Thanks supercowz and everyone for making the dual boot work.

I am getting ready to buy this tablet and have quick questions if you don't mind. Do you guys have a preferred site where you buy these from? Some of you have indicated that you knew what model you were getting even before it was delivered. Is there a way to find out which model you would get or is it random? Also, with official dual boot being so close to be available, would I be better off just waiting or should I just go ahead and buy now?

we advise you to buy from here, it is the biggest Teclast tablet seller, [MENTION=2470600]supercowz[/MENTION] and i bought our tablets from here on 11.11 chinese shopping festival and the tablet came as C8J7 which is a good ID..

http://www.aliexpress.com/item/9-7-...Core-Tablet-PC-1-83GHz-Retina/1862203196.html

First contact with the seller (Anna Fang-Echo) and say you are from XDA forum, Mr. Julien from France and Mr. Emrah from Poland say hello and advised to buy from here etc. and ask about the device ID. Say you want it to be C8J7 , ask them to double check.

addition : dual boot version is sale, its price is 227 usd with free shipping and normal android version is 211 usd with free shipping
[Teclast X98 Air 3G] supercowz:
I don't think dualboot is ready on sale, I will say presell, officially seller say 20december

U can order c8j7 android and transform it .. Up to u

U can order teclast from OKQI officially seller (say "echo I'm friend of Mr viey from France, small discount please...or smal gift if possible")

Hey Guys,

I'm just wondering how do you go into boot menu with this new BIOS? I'm trying to reinstall my Windows and I can't because there is no option to select boot menu. I can only choose Windows Boot Manager.

Whatever I do, it will not boot from the USB drive that I have inserted.

Is there a solution to this? Thanks!

---------- Post added at 10:27 AM ---------- Previous post was at 10:08 AM ----------

Wow this new BIOS has almost nothing in the BIOS options as compared to the previous old one. I can't even choose for it to boot from USB. The only boot option is "Windows Boot Manager" or "Disabled", which is really dumb...

This means that I can't install anything from USB!

---------- Post added at 11:22 AM ---------- Previous post was at 10:27 AM ----------

I've also tried pressing F7, F12 during BIOS, but it doesn't bring up any boot menu to choose from USB or eMMC boot.

Even after booting into Windows, going into recovery options and choosing to boot to the USB drive after a restart doesn't work as well, the system goes straight into Windows on the eMMC.

Also, I found that for those who have unchecked the dual boot option on startup can bring back the dual boot menu by pressing Vol + and Power button together when turning on the machine.

Just a quick cross post from the Air II thread which I thought would be worth sharing here:

I picked up this OTG USB Hub the other day. This device is able to act as an OTG cable AND charge the tablet simultaneously. Working nicely with a keyboard, mouse and external HDD plugged in. The vendor states it's compatible with the x98 3G. Pretty useful for docking or converting your tablet into a XBMC HTPC.

Teclast just posted a new BIOS for C8J7 on their website. It's downloadable at http://dl.vmall.com/c03xavafpc and has the title "Android System Update IFWI (BIOS) General tutorials and tools file (for X98 Air 3G (C8J7))"
