I did try with a 500GB 2.5" drive and it works, it can read it, but not safely enough...I would get uncomfortable clicking noises before plugging the hub in the charger.
[Teclast X98 Air 3G] acc007:
Today I installed latest 3d mark. It freezed about 10 seconds after launching the primary test, during the initial demo... So it's not Android only failure. Just another confirmation it is hardware fault. For me intensive 3d titles freeze on both android and windows... And temperatures never reach 60 deg. It is gpu only bug. Intensive cpu benchmarks can work ok (tested for 20 minutes both on windows and android)

but not possible convert to tablet to c6j7 bios from here? http://xdaforums.com/android/genera...-2048x1536-t2913035/post57539121#post57539121

Of course, need someone test this bios first, if made android version to c6j7 with windows running all thing properly...

or is at high risk use these bios?
[Teclast X98 Air 3G] SUMMERBREEZE:
Guys, to your attention!

Please dont flash any

DUMPED BIOS

to your device, or it will brick your tablet! the software method we use do not totaly dump the bios.. It needs to be hardware method..

As far as i know, two of us flashed a dumped bios to their device and they ended with brick!

C9J7 Base ROM

[MENTION=2470600]supercowz[/MENTION] ;)

Tough can't make it today, but taked some free time, so here we go:

C9J7 Base ROM

Descripcion:

- Based on C9J7 1.06 Stock KitKat 4.4.4 ROM

- Deodexed

- Zipaligned

- Chinese Apps eliminated (system should boot EN locale)

- Nova Launcher as default Launcher

- Added ES File Explorer (hate the default one)

- AOSP Keyboard default input

- Rooted (now should work as SuperSU updated today version)

- Google Play Fixed (integrated on System partition)

- Audio fix by Frontier (hope don't forget to add this one :confused:)

Three XML, one stock (for Android only system), other one stock without repartitioning (for reinstaling Android without modify partitions), and the other with 1Gb System, 512Mb Cache and 5Gb Data (repartition for Dual Boot).

TWO Links,

one for C6J6 (build.prop on /system merged with the new one)

https://mega.co.nz/#!ZcdnwDzJ!Kq4o-RDyMPYp7AC99V--kjyqqnhgAHQf7Ia0u-Hto7o

and one for C9J7 (build.prop original modified)

https://mega.co.nz/#!UVNCgACb!rrD5tRICirC7xcYj4YOU_k_w6glTZv2xS9W3_L6kjHk

PD: No tested yet, hope i can install later today. Please, report on root, try to execute SuperSU, should be OK.

ADVICE: Don't try if you're not sure how to recover or go back to stock.

believe or not believe (i actualy dont care what you think, as long as you think i write lie things), dumping bios with FTP -D command is not SOMETIMES enough for proper bios.

I am just telling people to be careful about flashing bios. It is better maybe until we see an official bios from Teclast (like c6j6 and C8J7)

For air ii users...

For X98 AIR II (HG6M) users:

I've just figured out this:

If you use the stock Android Rom (HG6M) available at http://www.teclast.com/tools/pad/pad.php for flashing Android on your tablet, the camera will work fine.

However, I am still struggling with Windows Screen and Camera Upside down problem.

One problem finally went away but the other is still alive.

BTW I found the new BIOS for AIR II (December 4, 2014) on the official website of Teclast.

Since I don't understand Chinese, please someone helps me to understand the details of the upgrade, which might means a lot to the Dual Bios system. It's a BIOS update!

I also got a hunch that the Intel HD Driver on Windows 8.1 would be a key player to make the inverted screen problem.

When I uninstalled it completely, the screen came to the normal temporally.

I don't yet understand what causes the Camera problem. It's really bothering and I am a bit tired to challenge the matter. :(

---------- Post added at 01:54 AM ---------- Previous post was at 01:37 AM ----------

new C9J7 today dump dual bios :

The Latest Bios for AIR II (HG6M)

https://mega.co.nz/#!SQhmgA6C!wtvgM84uTtO9ccDw-jMmG3zowSubwwWh_gxxWmuW-Qk

The Latest Android Stock Rom for AIR II (HG6M) Build Number (V2.02_20141105).

https://mega.co.nz/#!idIQibCY!qDFYnjWpgQYfNmhHQlylr9BGPjuvWb7SDvR-Ecy0vsw

Disclaimer:

The Stock Rom has a problem with Google Play Store and should be rooted for the Fix Guide.

Don't know the reason but VROOT and SRS ROOT didn't work for rooting.

Used this instead:

FRONTIERS X98 TOOLBOX (for easy rooting)

https://www.oboom.com/MCY35B1Z

Just extract it and run "1_Toolbox.bat".

The rest is self explanatory

Chose "E" for Rooting.

### Insufficient Memory ???

500MB is too small for the stock android rom ?

I followed this guide but now got the insufficient memory error all the time.

Extract the contents of the ROM to a folder. You should see a "partition.tbl" file inside.

This file controls how the 32GB eMMC in the tablet will be partitioned in this step.

Attachment 3048867

Copy the "partition.tbl" file FROM the Chinese download (either 5000 or 8000) TO the Android ROM folder that you extracted. Replace the original "partition.tbl" file that came with the ROM.

Edit the "partition.tbl" file in the Android ROM folder, find the second last line, which is "add -b 5931048 -s 10240000 -t data -u 80868086-8086-8086-8086-000000000008 -l data -T 0 -P 0 /dev/block/mmcblk0"

and change the highlighted number to the value of user space you want in Android. The number is a multiple of 2048, so let's say if I want 500MB user space, I would have to multiply 500MB x 2048 = 1024000 and input "1024000".

Attachment 3048872

I tried 300MB but it was too small, I think 500MB would be good if you're planning to use more Windows. Save the file!

Hopefully this helps. :o
[Teclast X98 Air 3G] WSOFT2002:
I also read this before which wrote by hjysc, what he said is, someone use a programmer (i think it's a hardware dump) to dump the bios and modify the content of address 400d & 400e to FF, so it can use on c6j6

But I can't find c9j7 org. bios, so I can't confirm it's true or not.

[Teclast X98 Air 3G] berwick:
sorry i m still a bit confused as i own C6J7, (not c6j6 or c8j7)

so if i want to flash it into dual boot are the following step correct?

1: flash dualboot bios from tablet windows (only one dualboot bio available for now, am i right?)

2: flash supercowz c6j7 light rom with desired partition table from PC

3: install win8 with that 2 USB prepared (which win8 WIM i should use c8j7? c6j6? or c6j7 from teclast?)

and i cant go back to original c6j7 bio as there is no bios dump available for now, right?
[Teclast X98 Air 3G] martyan:

Take heed regarding the warning about voltage, managed to fry the Flash while it was plugged into the programmer. Now waiting for some replacements to arrive before trying again. Component is a "Winbond 25Q64FWSIG" if you're in a similar boat.
[Teclast X98 Air 3G] ImJamIN:
So, is it the same or not?

Supercowz have you compare it with right software or not?

Wsoft2002, do you think that the more changes are for options in bios that we don't have now with dual bios?

Edit: I have compared the two bios; this is the difference :

119783 : 119783 Byte(s) diff

8268825 Byte(s) match

8388608 : 8388608 Byte(s) total

So, there are 119K of byte that are differents. Maybe Windows Lic Key ? (I don't know)

Here we must have a hero (with programmer!) that try to load the new C9J7 to test if it's work.
