Hi people, my tab is coming in two days!

I will check bios and try freeze issue, but later i would install windows only bios and remove android completely.

Please, tell me if these steps are correct:

1- go into bios, and boot from usb.

2- start windows installation. Q: Can i use an external cdrom with windows 8 PRO disk?

3- disk partitions Q: what i should do here? Can i remove all partitions and make new ones? Can i remove recovery partition?

About windows bing key, how i can get it before delete each thing?

Good day,

Can you guys help me out, what am I doing wrong?

I have a C9J8 which came with dual boot. I followed Hendricksons video. I went ahead and Installed the Mirke Rom with the partitioning (C9J7) with a 4 GB install. Now when I go to install windows into the dual boot menu, I don't see an option to install windows on the other partition like in his video and I'm stuck, any advice?

[Teclast X98 Air 3G] TC93:
Was that with the tablet totally shut down or was it in sleep/standby?

I ask because I currently have been trying out a Toshiba Encore 2 Write tablet and I need to shut it down completely otherwise if I leave it in standby mode it drains fast, like 20% in 3 1/2 hours. Maybe its a Windows problem.

The good thing about Windows 8.1 is that it boots up fast from a complete shutdown. Like 12 seconds for me.

C9J8 x98 air 3G Ubuntu

Has anyone been able to successfully boot into Ubuntu (or similar) using the stock x98 air 3G (C9J8) dual boot? Any steps I can follow?

I have managed to start booting into Ubuntu from a USB stick but something I have done in the setup causes the USB ports to be disconnected (or something, haven't worked it out yet) so after GRUB loads I get dropped into the BusyBox shell with no keyboard and no USB stick which means that I can't get any further. Graphics driver appears to load (although is inverted, that seems to be a common theme with these).

If there is any interest I can share my steps on how to get that far at least.

The Connected Standby battery drain is horrible, I've read you can install the AIR II DUAL BIOS, so that the drain is much more reasonable, but you lose GPS...

I want to flash dual boot bios on my friends device C8J7 android version 4.4.4 (it has factory single android bios)

I am using UpdateIFWI.apk but it never flash the bios. Did you have any issue like that?

It is the safest way to flash the bios thats why i am scared to the other ways..

What more do you suggest ? Please advise :crying:
[Teclast X98 Air 3G] TomaszD84:
Thanks, what about the Windows with Bing activation though, will I lose the OEM key by flashing a different BIOS?
[Teclast X98 Air 3G] mirek190:
The best way to flash bios is use toolbox ( 2nd post in thread )
[Teclast X98 Air 3G] grigoris_a:
If you have original teclast windows then use Teclsast bios utility to extract the key from bios and the to insert to new bios.You can download it here
[Teclast X98 Air 3G] TomaszD84:
Thanks, my installation is using the original OEM key, which I also dumped to clear text beforehand. I'm trying to inject the Windows key into the X98_Air_II.bin file, but even if I tick the "force" option, the file is not modified at all. Any suggestions?

(BTW. the google translator "Word Lens" option is great, otherwise I wouldn't be able to do any of this)

EDIT: I'm starting to suspect that I should have done this before flashing the other BIOS, does it inject the BIN file with the key from the currently running BIOS or from the current Windows installation key?
[Teclast X98 Air 3G] grigoris_a:
You first use the tool to dump your bios key and then flash the bios you want.
[Teclast X98 Air 3G] TomaszD84:
So it's too late now, because the BIOS I flashed doesn't have an OEM key, so I can't dump the key to inject it back to a BIOS bin file, correct? The Chinese interface is not very helpful here, I'd appreciate some help :eek:

I do have the plain text OEM key, is there any way at all to inject it into the BIOS now?
[Teclast X98 Air 3G] grigoris_a:
Yes its too late.I don't know if you can inject OEM key in bios.
[Teclast X98 Air 3G] TomaszD84:
That... would have been helpful to know an hour ago...

I don't understand why anybody else isn't concerned about this, is my OEM key of any use now? Will I be able to re-install Windows and activate it by typing the key I (THANKFULLY) have extracted to text?

Also, I wonder if every device has the same OEM key anyway... mine ends with XHHTT, can anyone dump their key and compare?
[Teclast X98 Air 3G] grigoris_a:
Since you have the key I don't think you will have issues with activation and every device should have a different key.

You can't blame us if you brick your tab, this is just ridiculous. I asked a few questions myself which are still unanswered, but this might be because it's a thread with over 600 pages and not a clear subforum. And you definitely should check out the first page. Everything is described there.
[Teclast X98 Air 3G] antony84:
First, i don't blame no one, i simply ask because i don't have programmer to reflash bios in case of brick.

Second, in the first page i can't find a tutorial to completely remove Android with its partitions, starting from a stock dual boot installation.

Third, in the first page i can't find a way to backup OEM key and restore it.

Maybe these usefull informations could be added in first page, so stupid people like me can avoid to make always same questions.

I will try by myself, risking the brick, and i'll report these informations for all.

Yea most people are looking to install dual boot starting with only windows or android.

I have been following this thread form the start and cant remember anyone going from dual boot to windows only.

Some have gone to Android only which I thought would be a good idea for the new 64gb dual boot tablet (I'm not a windows tablet fan haha)
[Teclast X98 Air 3G] perkinna:
Thanks Originalas. This was much simpler than my method! However it ended up at the exact same point, ie about 25sec after the 'Try Ubuntu without installing' GRUB menu option is selected communications are cut to the USB port. Ubuntu boots as far as it can but ultimately drops to Busybox prompt (Initramfs unable to find a medium containing a live file system) as USB drive is unavailable and of course keyboard wont work either so can't do anything at that point. Note that there is about 40sec of completely blank screen after selecting the GRUB menu item and it is in that time (I believe) that USB is dropped (I have a Logitech G15 keyboard that has the LCD display that disappears at 25sec mark). Unplugging / replugging does not work.

Also note that the C9J8 appears to be 64bit UEFI so don't need to do the 32bit bootia32.efi workarounds.

Any idea's as to what would be causing USB communications to be dropped? I've tested with 2 x keyboards and 2 x hubs and 4 x USB drives all with exact same result. USB still has power, but no communication to USB keyboard or USB drive.

---------- Post added 4th February 2015 at 12:09 AM ---------- Previous post was 3rd February 2015 at 11:47 PM ----------

Thanks vpx. I couldn't get any of those methods to get to boot (shift + restart from windows, F2 on boot). However pressing del to get into the bios and just selecting Boot Override -> USB Drive seemed to achieve the same outcome (I believe) and was simpler so I just went with that. Note that the C9J8 seems to be 64bit UEFI so didn't need the 32bit EFI changes.

Past that your method seemed to be more-or-less the same as Originalas, ie use Rufus to prepare the USB stick. Unfortunately comms to the USB port appear to be cut after about 25sec (blank screen for about 40sec) and once comms are lost I can't do anything further (cant use USB keyboard, etc).

ty for the pointers.

Win Battery drain

Hi guys, if you turn airplane mode on, there is minimal batterydrain in connectet standby (as there is no connected anymore...). My X10hd had normaly 3% drain every hour, with airplane on it has 0% in 2 hours. Here are some Scrips to simplify turning on/off, only use Win 8.1 update Version, the other one gives virus alert (?). You can pin them to taskbar and start.

Now we need a schedule or script to toggle them automatic if power button pressed.

It is not a perfect solution but the best we have at the moment.
[Teclast X98 Air 3G] Petepe10:
It is not random, it is part of the temperature management system, that kicks in at about 55 degrees by lowering the brightness to 40% (so if you already have low brightness you do not see it at all).

40% is pretty dark in bright light. In the system folder are two files that regulate this throttling - see some of (my) previous posts.

It could be a too cautious measure.

3. On left navigate to Event Viewer -> Windows Logs -> System

4. Press power button to sleep the tablet.

5. Press power button to wake the tablet.

.......for wake: Kernel-General 1

Good morning

apologies for coming in with questions blaring, i have read the first page repeatedly and looked at all the options so far.

i have just received an air 2 dual boot (HG8N) 32GB

I have quickly realised that i wont be using the windows partition

So, i would like to single boot to Android, with a nicely optimized rom no bloatware

i see on the front page there are a variety of Roms, all with specific model numbers listed

NOOB question: do i have to flash the corresponding rom ie HG8n (which doesnt exist yet) or the the 4 digit code in reference to a bios number which i should flash first?

[MENTION=1167021]Hendrickson[/MENTION]:

Right now Teclast's line of argument is that the HardWare is fine but the software/games/app that crash are not codeed/optimized for Intel architecture.

We all know that such denial from Teclast has no logic but it will be nice if we can prove it with other brands using same SoC.

Can you please make a video on Onda 919 Air 3G Dual Boot to establish the fact that 3D error is not due to Intel-Android incompatibility.

You just need to run Unity Benchmark app @ 1080p. Also please use a CPU temp. overlay in the video.

Also please run the Terminal script to verify that the min and max GPU values are set to 313Mhz & 646Mhz respectively.

The idea is to record the frequency variation of CPU and GPU along with temperature history during Unity Benchmark or any other 3D test.

This video also blows away the illogic of Teclast.

However, this request is not critical in nature. ;)
