so do you think the oficial (can you please add the link for it?) dual boot bios by teclast is better than we use right now(the dual boot bios from chinese forum) :confused:

---------- Post added 8th December 2014 at 12:08 AM ---------- Previous post was 7th December 2014 at 11:49 PM ----------

this is a SYSTEM issue.. build.prop located in /SYSTEM folder and clear data cache and wipe dalvik from recovery mode wont change anything

battery issue

Hey guys anyone has battery not showing correctly in windows? Mine is on 31% for three hours now
[Teclast X98 Air 3G] Hendrickson:

i made with 2gb internal memory for android ......

to change the internal memory open partition.tbl with notepad++ and change this line

add -b 5931048 -s 16384000 -t data -u 80868086-8086-8086-8086-000000000008 -l data -T 0 -P 0 /dev/block/mmcblk0

reload /dev/block/mmcblk0

to this line

add -b 5933056 -s 4194304 -t data -u 80868086-8086-8086-8086-000000000008 -l data -T 0 -P 0 /dev/block/mmcblk0

reload /dev/block/mmcblk0

for 1gb only paste this line instead

reload /dev/block/mmcblk0

in both cases you will need to use link2sd so you can move applications to sd card, sd card will be read and write on both windows and android.

I think there is instruction on the texdroider app page in the play store that tells how to push their recovery folder via ADB.

I just changed the build.prop file. So much easier than messing about with apps.

I then changed it back to 320 dpi because it didnt seem to make the tablet run any better, everything just got small :)

guys, you know i am on bootloop and wanted to flash again the android but though i do everything correct, when i plug the usb cable in DNX mode- waiting for fastboot command, intel manufacturing tool doesnt start at all!!

i dont know what to do.. drivers seem ok, it is just in bootloop cos of messup build.prop

what do you suggest?
[Teclast X98 Air 3G] krisbliz:
Check VID PID values, also check usb port,cables etc...
[Teclast X98 Air 3G] supercowz:
did you try to boot android secure ?

i try on my side .. wait

OK should work.. Work for me

to enter secure safe mode

boot your tablet one time and select andoid boot, if you are allready on that mode, turn off your tablet and wait a bit

then press volume- (volume down) and power and stay push on this until android boot, you should be in safe mode

then via setting do factory reset .. voila ... no more bootloop.
[Teclast X98 Air 3G] SUMMERBREEZE:
update : I was able to flash after uninstall all drivers and its tracks from device manager.. i mean, i didnt just uninstall program, i also uninstall the drivers left in the system

Successfully updated my C6J6 to dual-boot, thanks for all the people who write these tutorials.

After manual installation of Win8.1 Pro and all the drivers, I cannot change brightness at all.

I have seen issue regarding battery in past pages, but nothing related to brightness control.

Am I missing something necessary to control it, or is it bios related ?

Losing Android Install.

Hey guys, I have successfully flashed the dual boot bios. Using the tutorial I got Android (Cows) up and running no problem. I then installed Windows successfully but it continues to wipe out my Android install. I end up with only the Windows option on the OS selection screen. Anyone have any idea what I'm doing incorrectly?

Thanks

Can any one upload yours real racing data that will be work?

I tired of searching and downloading with google play and always will be failed
[Teclast X98 Air 3G] HDtracer:
OK I have been trying a few games.

RR3 just crashes as soon as I open it. Dead Trigger 2 plays the opening movie and crashes.

Asphalt airborne plays excellent with no crashes after 20 min.

Into the dead plays well with no crashes

I can only conclude that there are games out there that really just don't work or work well on Intel based android.
[Teclast X98 Air 3G] ISEENOEVIL:
I had the same issue as yours and realize that the DISKPART cmd in the script is wiping the drive. Check the Images folder on your WINPE/USB disk open WIMPART.TXT this is the cmds use in the script. You will see the "clean" & "convert gpt" as well as the drive that will be created and listed.

Also check the sequence performed by the "Main.cmd" under the script folder on the WINPE/USB.

This pointers should give you an idea why the Android part is being wiped.... hope that helps
[Teclast X98 Air 3G] davidonabus:
Thanks a ton! The Win8.1 full image worked great. The Win8.1 Lite doesn't work and results in deleting the Android partition. I'm good now! Much appreciated.
[Teclast X98 Air 3G] Petepe10:
Ask Mirek to send you / summerbreeze his apk of the game and his build prop lines on cpu.abi to make sure what it is.

Like I said before, x86 and arm versions may be around. If all works except some games it seems more likely to me that the game is not fully supported by intel. If a game does not show up in the Play store it is an indication that it was not released for the platform. Sideloading of apk's may work sometimes but not always.

Games are a bit difficult to check of course, since the course of play varies with the user input, so crashes are less predictable.

I installed SUPERCOWZ LIGHT ROM for Android. On my c6j6 when opening the camera app (in Android) the picture on both cameras is inverted! (dual boot bios installed).

But I'm referring to Android not Win 8.1! (On Win 8.1 I already did it.

I don't think that bios from teclast website has dual boot. But I didn't test it.

This is link :

http://www.teclast.com/tools/pad/pad.php

Click left button and insert your model for download bios

If you try to download bios for c6j6 and for c8j7, teclast remand you to the same page with the same bios. That's strange.
[Teclast X98 Air 3G] LVL91:
That's nice to know! I am going to try the full windows install this evening. :)

I thought it was a problem with both the lite and full version.

This is about the full chinese version right? (link above the lite version link in post from keepfished dual boot tutorial right?)
[Teclast X98 Air 3G] ImJamIN:
You have modify only /data partition and not /system, right? And /cache?

If so, what's about completr storage of full android ? Before was 10gb, and now?

I have the same problem, check reply above this reply. You have to install the full version probably.

I also have the reduced capacity issue after flashing dual boot bios.Returning to win only bios did NOT fix the issue.Also there is major issue with connected standby with this tablet.Battery drains are huge with no possible offenders in sleepstudy reports.All probably due to bios.I wonder if someone with a Windows purchased tablet(either 3g or air)could make a sleepstudy and battery report to show us.

INVERTED CAM on this Android!!! on C6J6 with DUALBOOT

Hi guys and [MENTION=570060]Supercows[/MENTION]

On a C6J6 with DualBoot Bios I've installed successfully both Android and Windows.

The Android was from SUPERCOWS ANDROID 4.4.4 C6J6 AND C7J8 ROM For Both: https://www.dropbox.com/s/c0kg06aq3e...lBoot.zip?dl=0

The funny this is that I have INVERTED CAM on this Android!!! (Just like in windows - but there it's solved with the known fix).

The SUPERCOWS ANDROID as I can see was for X98 Air 3G(C8J7). Is there a differense in the camera?

Has anyone else has the same issue? (On a C6J6 with Dualboot)

Hello to everyone

first: Thanks a lot to everyone. Your work in this forum is fantastic.

any ideas???

It seems that the SUPERCOWS ANDROID 4.4.4 C6J6 AND C7J8 ROM For Both (https://www.dropbox.com/s/c0kg06aq3e...lBoot.zip?dl=0) is causing inverted camera on Android in dualboot c6J6! I'm trying to figure out if the other light version works properly!

[Teclast X98 Air 3G] PWMx:
You just forgot to change the file permissions.

And no need to reflash everything. You can use ADB shell to change the permissions afterwards.

( Don't ask how I know this ... ;) )
[Teclast X98 Air 3G] SUMMERBREEZE:
no my friend, you are wrong, your gpu is also problematic and possibly faulty like mine. Also so many people has the same issue but they didnt face it yet.

Why can someone else play RR3 but you and i cant at all? Why you and i cant play dead trigger but someone else can? and a lot of games like that.. and there is no guarantee that a few games you play right now will never give you issues later, this is a very promising but not very well build inside, typical chinese tablet. maybe thats why it was this much cheap, thats why it became very popular.. If you are still happy with your tablet and believe it is just intel&android (x86 & arm etc) issue and wanna keep it, i respect it, no problem for me at all, but i can not play almost any games at all and i didnt pay 200 usd plus same taxes at the custom for a tablet that will never let me playing any games at all!

By the way, i am trying to contact with my seller on aliexpress for this issue but no answer for 2 days.. I keep asking the same questions, trying to negotiate for both sides good but no response at all.. They were giving answers very quickly all the time before buying the tablet and it was nice but now, why they dont response now? ;)
[Teclast X98 Air 3G] severall:
Thank you. I'll try this today. Just learning how to use ADB shell ;) It will be mush easy playing with this tablet if we have a CWM recovery.

[Teclast X98 Air 3G] SUMMERBREEZE:
Look at their answer, they say c6j6 and c8j7 dont have the same GPU! this is a bulls.hit lie! we all know they are exactly same. And noone knew when they purchased they would get c6j6 or c8j7 ? In their product page, there was nothing writting about hardware or gpu change, i dont remember this, so all of us purchased this tablet with a high hope for gaming.. And most of the tablets have this issues, were purchased on 11.11 shopping festival.. I think the seller just sent the defected or returned tablet to people because they were promotional ones.. I mean, if i bought without any coupon or discount, i would propably GET a rock solid one.. :silly:

Overheating

This is overheating issue.

I opened the device and there were two thermal pads. On top of Intel SoC and other covering two DRAMs. Other two DRAMs were without pads.

Those pads were too large, so I was able to cut several smaller pieces out of those. Now SoC, all DRAMs and PMIC are properly covered and also eMMC has smaller piece on top.

Heat definitely gets transferred to the can lid. It gets uncomfortably hot. Too hot to keep finger on it. PMIC and SoC areas seem to be hottest spots.

Also can lid to the aluminium back cover interface is poor. Let's see how I could improve that ...

So this overheating issue is really two fold :

1. Thermal design and implementation of it is not sufficient to keep all components cool enough in worst case scenarios.

2. System level thermal throttling does not work properly - Probably SW (firmware) issue.

(In many practical systems 1. cannot be guaranteed and thus 2. is needed to avoid crashed and freezes ...)

[Teclast X98 Air 3G] severall:
Regarding the overheating..

When i have Windows 8.1 installed on C6J6 i run Intel Burn Test + Furmark. There's no games or programs on earth that can produce more heat than this combo.

After 1 hour of testing nothing happens and CPU Temperature was about 70C which is good. Maybe my tablet manage heat better ? Or these crash problems have a different cause.

Currently i'm on android. What game is most demanding for SoC ? , i'll my try my piece.

[Teclast X98 Air 3G] PWMx:
Yes, for any continuous heavy CPU or GPU computation ... Games, benchmarks looping etc.

(Components gradually heat up more than can be dissipated and nothing is holding back. I.e. cooling is insufficient and throttling doesn't work.)

[Teclast X98 Air 3G] vgiozo:
The Windows version that is shipped with those tablets is the exact same one that other people use to flash it themselves. It is the Windows 8.1 Bing version, that prevents manufacturers from making a deal with Google to change the default search engine to Google search (but the users of course can) and Microsoft lets them have it for free, in order to deal with Android competition.

Of course "sneaky" sellers will apply a +10-40$ overhead for the same tablet, even though the OS is free...

To sum up, you dont get a licence key...because you dont need to activate it, it is already licenced. What you get is Office 365 Home 1year subscription, but I don't think it is worth it.

I would think like that (get Air II and be done with the flashing process) but truth is, it will cost you more, and you will likely lose more money when you want to resell it to buy something else, because the other person will look at the features and find the Air II lacking...and where the Windows 8.1 came from (pre-installed or post-installed) wont make any difference.

Get the one with the richer feature set and just follow the guide carefully...you dont need 3G and GPS? Dont use it...
[Teclast X98 Air 3G] LVL91:
Incorrect. The bing version is meant for tablets smaller than 10 inch. (around 10 inch I think)

My windows is not licensed and it's asking for a key which I need to pay for...

Edit: Windows with Bing is meant for devices that would costs less than 250 dollar. At least that is what multiple sources are claiming. But manufactures provide the devices with keys installed. Maybe Teclast can give us keys. But chances that is not going to happen I guess...

[Teclast X98 Air 3G] Glamir22:
I am currently running Windows 8.1 with Bing, if I install Windows 8.1 Pro from the ISO do I just need to install the Teclast drivers to get the touchscreen working?
[Teclast X98 Air 3G] vgiozo:
Actually it is correct,

http://www.howtogeek.com/195934/what-exactly-is-windows-8.1-with-bing-do-i-have-to-use-bing/

but I guess specific keys are provided to manufacturers and you dont get any unless you buy it with Windows pre-installed...that is something worth noting.

Let me get this straight though...the Win8.1 version that is provided here is demanding an activation and a licence (within what timeline) ?

That means then that people here who have installed it and are not complaining either do have a separate key or the have gone another way about activating them.

Hmmm if only those damn thieves of sellers wouldnt charge up to 40euros for the Teclast Air 3g with Win8.1
[Teclast X98 Air 3G] severall:
Yes, i just install clean Windows 8.1 Pro. Link to download driver is in the first post at this thread.

[Teclast X98 Air 3G] vgiozo:
It's the drivers that are beta, not the OS. Also Teclast is already shipping those beta drivers with Win8.1 right now.

That is, we will never get a fully licenced version of Windows, unless we buy that tablet with Win8.1 preinstalled...

...kind of foolish for us even to expect that Teclast would release fully licenced windows downloads for anyone to acquire....
