[Teclast X98 Air 3G] BoORDeL:
I don't understand your problem.

Why blaming TECLAST for letting you install WINDOWS 8 on your TABLET by giving you BIOS and DRIVERS?

Have you paid for a windows licence or just bought android tablet?

this is XDA and here we are talking about moding our device.

If you think you have been fooled by TECLAST about windows LICENCE use THEIR FORUM.

I think we have only to thank TECLAST for the opportunity

My 2 cents
[Teclast X98 Air 3G] vgiozo:
I dont have a problem and I am not blaming Teclast for anything.

I am simply trying to figure out if as buyers of an intel SoC tablet which is advertised as win8.1 upgradeable we can get Win8.1 licenced (manufacturers get it for free for low cost tablets) as an "add-on" or this is only true if you get Win8.1 preinstalled on the device.

That is the extent of this discussion...no blames, just clarifications .... because I did not see this issue coming up before in the discussion and was wondering whether software downloads offered here in the guides was actually licenced and working as if the device had been bought with the OS built-in/preinstalled (i.e. if OS was already activated or would activate if a supporting device was found running on it)

The conclusions of this discussion are

1) No, the Windows8.1 Bing version that is free for manufacturers and buyers comes licenced only when pre-installed. Neither Microsoft nor Teclast is giving away keys to buyers of tablets under 250$ that support Windows

2) It was very naive to think that Teclast would just offer licenced copies of Windows like that on the internet, for anyone (not limited to its clients) to access...doing so would equal pirating software...

Again that is not blame, it's solving questions and using common sense.

The only thing to settle now is if by contacting Teclast with proof that we have bought the device, we can get a key to activate Windows8.1.

Personally I don't consider it likely...again no blame.

I am on the verge of ordering and interested mainly running the tablet on Windows 8.1, so I wanted to know if buying an Android version of the tablet and upgrading is practically the same as buying it with Windows preinstalled, plus the manual process and risk of OS-change. That is all.

Seems like I better order a tablet with preinstalled Windows or check whether it serves me better to buy it separately, if the extra cost is similar.

[Teclast X98 Air 3G] tumich91:
Is still problem with refresh 48Hz and inverted camera on Win mode?

Im waiting for now 30 days and still dont get it from Aliexpress :/

Am Teclast should give z3735d like on Air wifi and won't be problems :(

also that's true that z3735d better run 3d games than z3736f? Probably cuz of drivers..

Only Teclast Air 3G is only one tablet in the world with this shi* z3736f..
[Teclast X98 Air 3G] BoORDeL:
no i've installed a clean windows 8.1 pro (using win toolkit to modify iso with teclast drivers) and office.

Anyway i've noticed that standard windows installation create a 4GB partition for recovery and that could be the difference of space used.

---------- Post added at 05:30 PM ---------- Previous post was at 05:29 PM ----------

Yes the 48Hz problem persists only in windows (not in linux or android) because of INTEL DRIVER.

For the camera something is mooving because teclast AIR II is not affected by this problem (http://bbs.teclast.com/thread-256976-1-1.html)

I have changed my tutorial already this morning and only the Windows ROM compatible with dual boot is there now, I have removed the others.

You can safely download the Windows image from my tutorial now, but it's from Baidu and painfully slow.

---------- Post added at 07:30 PM ---------- Previous post was at 07:30 PM ----------

Yes, I recognise this problem, and therefore changed my tutorial this morning to reflect this change already.

---------- Post added at 07:33 PM ---------- Previous post was at 07:30 PM ----------

Yes, I have read reports of the chinese tablet user going into aircon room and blowing the fan directly on the metal back cover of the tablet, and the game never crashes. Without aircon, the game crashes in 10 mins.

---------- Post added at 07:34 PM ---------- Previous post was at 07:33 PM ----------

I have complained about this so many times in previous posts, and I even posted my sleepstudy on this thread, but no one seems to care about what I'm saying about connected standby. I've turned to the Chinese forums for help, and apparently they are facing the same problems too. I have shown detailed sleepstudy screenshots...

I dont really think so mate.. maybe someone who can play these games can open the backcover of the tablet ( [MENTION=2198172]mirek190[/MENTION] can you do that mate? ) and submit detailed photos and we can compare them with yours.. cooling, thermal pad, hardware etc.

I also have an idea, it would be great if we could put the tablet (as back cover open) on a colling pad like this and see the results :

As your tablet is freezing, could you try some cooler blowing on your tablet and check if it still freezes? Then you'll have confirmation if it is a matter of overheating.

I don't think it will have better results then win8.1.Since in the sleep study report shows that the tablet "sleeps" well(99% in deep sleep) and battery drain is high it is 99,99% bios issue.If it was driver it would report the device with the problem.And there is another thing to keep in mind.Since the battery reports false state we really don't have the percentage drop that sleep study states.

Funny thing is that in Android, the battery drain is almost zero when I leave it to sleep with the dual boot BIOS... that's something quite reassuring for me now... But with windows, standby time is horrendous, so I think it might be either problem with Windows implementation of connected standby itself or the windows drivers.

Hi summerbreeze, i have seen your video and I think that your cpu/gpu isn't broken or fault.

Your situation is common among custom rom with undervolt/overvolt of gpu/cpu in every smartphone and tablet.

I often have had this problem when I play with voltage and overclock.

So I think this is a problem of software and not hardware. We must concentrate to developing kernel and recovery and I belive that most of this problem will gone.

Or we must wait a new dual bios that correct some instructions for work well with c8j7.

P.s.: try to load the last official bios from teclast (web) and then try to play again to see if work well...

[Teclast X98 Air 3G] majkel_94:
But what about the emulated SD? I mean that in stock Android the 26,5 GB partition is for apps and files also which means all app data (maps, obb packs, etc.) and files like downolad files or DCIM are in internal memory.

Can somebody change this behaviour like it was on phones 2 years ago? Only apps on /data, all other files on external SD Card :P
[Teclast X98 Air 3G] Jote:
Intel like Mediatek, Allwinner and Rockchip do not want to release a single line of code and they don't have to. However phone/tablet manufacturers are using open source code from chip manufacturers as base and terms dictate that they must release it under GPL. Right now they are "stealing" and we are left without Cyanogenmod or any other custom rom with fixes that Teclast cannot seem to be able to produce..

If we would bet on release date of Android 5.0 to X98, I would pick date "never". I would probably win.
