Hey,

Thanks for help.

As for the ROM - I thought the same, that this is not connected with this error. I was just clue less ☺

I will try with the adb. I didnt know about pushing roms via abd. Need to check it then.

Also will try the REVO uninstall. Because of this i tried flashing from different computer.

Will definitely let you know.

Thanks again
[Teclast X98 Air 3G] HDtracer:
Just a thought, if you have the original Teclast rom for your tablet you could replace the system.img file with the custom rom system image and try flashing it.

That should keep all the stock partition/recovery/data/droidboot, etc files and just flash the new system image.

I dont know how it will affect the windows partition though.

I dont have a dual boot device and havent looked at the stock dual boot rom and partition table.

Could be a way to see if there is a faulty file somewhere. (just remember to change any file names so there is no chinese characters in the names)

Safest way would be to push the system.img file with fastboot I think.

I experience strange behaviour of the OS-selection page:

When i restart windows, OS selection screen will always come up to let me select windows or android. Because upper left tick is set this is normal. The same behavior if i shut down windows and then press pwr.

When i shut down Android (there is no restart button and restart-apps from market do not work) i have to press pwr & vol+ to get OS selection. Only pwr does not bring up OS selection but boots again in android.

Is this normal or is my tablet faulty?

:confused:

EDIT: Strange behaviour only happens if connected to charger (no hub), if tablet is disconnected, OS selection comes up after android, too!

Windows 8.1 bing key

If I buy Android only version and want to dual boot, would Windows 8.1 bing edition activate on it's own? Or do I need to buy bing key from somewhere?
[Teclast X98 Air 3G] TomaszD84:
If you have the Windows only or Dual Boot version from factory, you WILL LOSE the Windows OEM Activation key (and your Windows activation AFAIR) if you flash your BIOS, nobody seems to realize it or forgets to mention it.

Dump the key to clear text using tools found here http://forums.mydigitallife.info/threads/40897-Guide-to-preserve-Windows-8-x-OEM-Activation and/or use the tool Teclast provides to inject the current OEM key into the BIOS image that you're planning to flash.

---------- Post added at 09:18 PM ---------- Previous post was at 09:15 PM ----------

The Windows with Bing key cannot be bought in retail, it is only for OEMs. The key is injected into the BIOS at factory if you buy the Windows only or the Dual Boot version, so there is no legal way to activate Windows with Bing if you buy an Android only version.

You could buy a standard Windows 8 or Windows 8 Pro license or get the latest Windows 10 Preview for free.

Thanks I'd buy dual os one. And since the price difference between 32GB dual and 64GB dual is not that significant, I'd got for 64GB dual.

Just one more question, I'm guessing these new 64GB ones are newer model C9J8, which I believe already has the known fixes, is that so? I'm more concerned about the touch issue seen on bunch of C7J8s.

Hi

In Windows when you change the resolution to lower, is the screen just like

Regular tablets with that resolution?

I mean when you set to FULL HD (does it have FULL HD?) Is it just like Xperia tablet Z

For example? Or if set to 1280*800 is it just like a galaxy note 10.1 or any regular tablet with

This resolution?

Or it just goes up scaled and awkward like desktop PCs ?

And something else,I was wondering aren't tablets like PiPo P9 3G with android 4.4 better than this one? PiPo P9 3G has RK3288 and Mali T768 (better than z3736f right?) While using a lower resolution of 1920*1200

Or isurface pro with dual OS and z3735f while using 1280*800 screen which should have a lot better performance than teclast x98 3g both in android and Windows, right?

Sorry if it was too long. I appreciate your advice.
[Teclast X98 Air 3G] JagSagaz:
What does "better" mean to you? Remember that you can't have Windows installed on a Mediatek Tablet, so you can't compare both tablets in these terms. Maybe you mean Android vs Android, but in this case I'm sure there are even better models than these two.

Hi,

I just received my Teclast X98 air 3g 32Go windows only version (C6J7). :good:

I'm very happy, especially because it was won at 80% of the value by a game/contest from planetenumerique.com and hongkongeek.com (thanks again to them)! :D

It's window 32bit with Bing version, and the emmc is a BiWin.

I just have time to play a little with it, install an antivirus, and also check some of the bug still present in this version:

- both cameras are inverted. I will try the fix given on first page

- Battery report from windows shows a full charge capacity of 14,432 mWh. i will try the fix given on first page

- Chinese translations in some windows menu label (network sim 3G mode, ...) but maybe it's only in the french configuration of windows?

I have 2 questions:

- is there a way to make a full backup or create an image to be able to restore the system in the future? It seems that there is a small partition for system backup, but how to use it?

- is there an update/upgrade to do before applying individual fix (camera, battery capacity, ...)?

Thanks

About bios problems

I was thinking... the only problem with C9J8 bios is battery drain in windows sleep mode. The rest is full working without any fix.

Instead, using a single boot bios, like air II ones, or C6J7 similar ones, fix the battery drain issue, but bring other problems, like camera inverted and battery capacity issue. Is it correct?
[Teclast X98 Air 3G] kiru:
Are you sure you have a C6J7? I only ask because you should not have the inverted camera issue. I have a C6J7 and everything is working out of the box. I would try to restore windows first before trying anything else. You can initiate the restore within the settings menu in Windows, but please keep in mind all the restore menus are in Chinese.

Battery drain

Hello.

I have made some research, and my conclusion is that dual boot bios C9J8 does not have the ability entering in sleep mode. When you press the power button it only switch off the screen.

You can verify this in windows, open an command pront window as administrator, type "powercfg -a", the results are: not capable entering in s1, s2 o r s3 standby modes nor standby in battery mode.

Can someone with only windows bios C6J7 share his results?

Thankyou
[Teclast X98 Air 3G] Bor-ka:
No, aspect ratio is different. You can't just fit 16:9 resolution in 4:3 tablet, there will be black borders or such.

If you go for movie (16:9 aspect ratio) or gaming (compatible android GPU), then other tablets are better.

On the other hand, if you like 4:3 or need windows installation (office, old games, specific software, you name it) it is a very good choice.

[Teclast X98 Air 3G] capillonpub:
Hi,

First i'll correct one point:

- After one full night charging, the maximum battery capacity seems more correct: 29,720mWh. so maybe no need to apply any fix !

In a command prompt, copy and paste the command below, and press Enter:

powercfg /batteryreport /output %USERPROFILE%\Desktop\battery_report.html

About the tablette version, C6J7 is want is printed on the back of the cover, is there any way to check this in the system?

To be more clear when i said that the camera is inverted: if i open the website: www.testmycam.net

- with the tablet in "portrait" mode, camera lens in upper left and physical button on left, the top of the picture is on the left side of the window, the back of the picture on the right side of the window.

- with the tablet on "landscape" mode, camera lens on upper right and physical button on top, the top of the picture is on the bottom of the window, and the bottom of the picture on the top of the window.

How to make a dump of the bios?

I'll certainly will do this, but first i will check the video link on the first page to swith frm chinese to english !

On my brain new C6J7: It's difficult to comare exactly because my tablet run windows in french, but i read that s1,s2,s3 & hybrid (s3?) are not available.

I'll switch in english to check but now there is 23 update to apply before restarting :(

edit: in english now, the following sleep states are available:

standby (connected)

hibernate

fast restart

not available: standby s1, s2, s3, hybrid sleep

Earlier in the thread someone recommended Andoird only from AliExpress, saying that dual OS can easily be loaded. Then I learned that unless you have Windows preloaded, you don't have the OEM keys. And without those, you can not install windows.

C9J8 SkyGo won't work Windows or via Android app.

I've not had to do anything with my Teclast 3g air, and have been fairly impressed .This C9J8 version seems far more stable than other previous ID's noted throughout the thread, however one big problem for UK users is that the Skygo app in the play store thinks the tablet it rooted. When I try via the dual boot method and switch to Windows it doesn't allow me to register the tablet. Has anyone cracked this preferably via Android as there are far more free VPN apps when I am out of the country.

I believe that the tablet is indeed rooted - I've played with some chinese apps and seen a button called "s-thg root" where s-thg was in chinese.

Hi, the tablets dont come rooted but have a program installed to allow rooting, which triggers detection by apps.

Rootcloak doesn't work on most apps and Rootcloak plus doesn't work on Intel processors.

Hide my root may work, but it disables root for all root required apps.

I think the only the only real way to use apps that detect root is to completely unroot with vroot or maybe supersu.

It is stupid that apps look for root as any Windows or Linux computer with admin rights is basically "rooted"
