Can i answer call when I am in Win 8.1??? dual boot to WIndows

I just received the teclast dualboot but just to check is the dualboot is totally different than the youtube where you can just click the button it dual boot to android or Windows. Now its i neet to reboot to select.

I am planning to use it as a phone function. But it I am in Win 8.1 i will not get any call? anyway to fix it?
[Teclast X98 Air 3G] mirek190:
Ehhh power off - just keep button power for 6 seconds that's it

I didn't change size the top bar for your information.
[Teclast X98 Air 3G] fred7106:
Thanks. Probably is same strange think of the theme.
[Teclast X98 Air 3G] kosrica:
Ok, I will ask them to test the unit before the shippment and to confirm me the HW version C9J8.

Could you please tell me how do you find the browsing experience on this tablet, especially in Win 8? Is it smooth? Can the tablet be also used for some light editing of Word/Excel files?
[Teclast X98 Air 3G] Petepe10:
No solution for freezing by changing throttle behaviour

As follow up of prevoius posts, even removing zone 1 and 3 throttling did not prevent freezing of RR after a while, so no luck tweaking so far. Bad voltage regulation in combination with temp seems to remain the lkely cause to me.

---------- Post added at 04:38 PM ---------- Previous post was at 04:36 PM ----------

Is there any further activity on Chinese forum on freezing?
[Teclast X98 Air 3G] SUMMERBREEZE:
apart from this 3G gaming issue, it is a great device, browsing is very smooth and fast. You can use the world/excel editing with no problem, with hdmi output, you can connect to your HDMI or DVI-D monitor in desktop mode and use it like a portable PC..

the atom chip is well enough to capable the other apps too.

That´s the way real dual boot works. The video doesn´t show real dual boot, it´s only an emulation.

Windows doesn´t support phone function yet, maybe Windows 10 will do?

Hi,

there is some minor bug with your rom default settings - there is some text displayed under the clock, but only in portrait mode. I have Polish language, the text was different on English language... Have a look below. It is some Apex setting. No problem with Nova launcher.
[Teclast X98 Air 3G] fearxl:
I'm agree with you. It's a temporary solution. I think Teclast will don't find a fix.

List of members with no 3D issue on Teclast X98 Air

I am trying to consolidate the statistics of members with

NO 3D issue

on Teclast X98 Air.

I hope this list shall help the developers and troubleshooters here to get that valuable info/data/config when needed.

Hey Guys, [MENTION=2470600]supercowz[/MENTION] [MENTION=3014815]SUMMERBREEZE[/MENTION] [MENTION=2198172]mirek190[/MENTION] [MENTION=281521] jcespi2005[/MENTION] [MENTION=1167021]Hendrickson[/MENTION] [MENTION=5653798]Petepe10[/MENTION] [MENTION=323861]ImJamIN[/MENTION]

If you guys approve of this please let others know about this too

How to test ?

Run at least the first two apps/games and check if the tablet hangs/freezes. Please test the 3rd item if first 2 are successful. The more the better :)

thanks, it is a good idea but Real Racing 3 (PlayStore) should be in the list as number 2 :) also [MENTION=4777359]acc007[/MENTION] has C8J7 and has gpu issues too
[Teclast X98 Air 3G] mnitstanley:
You are right. I took the list from you only.

Re-arranged it because Riptide GP2 is a light weight game and users won't mind testing it compared to RR3.

Still should I shuffle again ?
[Teclast X98 Air 3G] BrocasHelm:
Just some info on testing, I tried unity benchmark today at 1080p and it froze at the fifth attempt(one after the other). Still the freezing issue exists, so run it several times, not only a couple. Also RR3 froze after like 15 mins of playing, in a race that took over 2 minutes. Earlier races that ended in 1 minute or so didn't cause me freezing issues.
[Teclast X98 Air 3G] SUMMERBREEZE:
i am also sorry for you mate.. it seems only a very few people has a good piece. and most of others dont even know that they have defected one :(
[Teclast X98 Air 3G] BrocasHelm:
[MENTION=4915543]mnitstanley[/MENTION] I have a c8j7 but I shouldn't be on that list, my tablet has the freezing issue. I just posted earlier so that people do lots of testing to be sure, else they might think that their tablet works fine and when the time comes for serious 3d gaming they will have the freezing issue.

PS: Got mine from aliexpress seller Tina Wu, not Anna Fang.
[Teclast X98 Air 3G] Petepe10:
Hi guys,

No problem to test, but games are a bit hard to compare as it depends also on skills and it takes (me...) very long to get somewhere. Are there other (deterministic) stress tests than OpenGL, maybe? Also should there be a temperature overlay on screen too?
[Teclast X98 Air 3G] malojk:
What model number, c9j7?
[Teclast X98 Air 3G] mnitstanley:
Kept your handle there because your case is better than many and the list isn't gonna be that long :p

I also got mine from Tina WU and has got the same problem. Did you contact her regarding this ? She said that I was the first to report this issue.

I contacted her this morning, sent her videos. She shall be replying soon with a course of action.

---------- Post added at 01:12 AM ---------- Previous post was at 01:09 AM ----------

So far this is the only method to test at hand. Temperature details too shall help. BTW, how to temp. overlay and FPS overlay ? which apps ?

The idea was to put that info out there so that troubleshooters can contact the 'lucky ones' directly.
[Teclast X98 Air 3G] BrocasHelm:
I have contacted her the last couple of days, I have a video uploaded for her to see(not YouTube as she told me) and new we are discussing through whatsapp. Anyway, we can discuss that through PMs if you want to keep the off-topic posts here to a minimum.
[Teclast X98 Air 3G] mirek190:
Could someone flash my rom c6j6 to c9j7 - make flash system only - to check that everything works ok ?

I assume the camera will be inverted only.

But I need testers that's will make my work easier - thanks .
[Teclast X98 Air 3G] SUMMERBREEZE:
the other stress tests (like RAR test, 3dmark, antutu, stabilitytest app) dont really test the cpu/gpu, they are staying very light for the SOC. but RR3 and Unity OpenGL 3.0 are very easy to try and dont require any skills at all :)

look at my video, i didnt even start the game lol ;)

https://www.youtube.com/watch?v=w1-tiNtrgiw

so the best stress tests are the OpenGL 3.0 benchmark and RR3 by so far :highfive:
[Teclast X98 Air 3G] Cozla:
I also have a 3D issue :( My device id is C8J7. Seller OKQI
[Teclast X98 Air 3G] mnitstanley:
I couldn't even get that far :silly:
[Teclast X98 Air 3G] SUMMERBREEZE:
Please ask them, the new batches (Dual boot - C9J8) are clean and have no problem? cos Anna Fang told me the new batches will be clean(they always say this actualy but nothing changes :cyclops: )
[Teclast X98 Air 3G] Cozla:
I have the same.

I also use polish language and in my case there is word "aplikacji" in two lines.

P.S. Guys is there posibility to make sub topics like android roms, widows, dual boot, 3D issue and more becouse in couple days it will be 5000 post and it getting hard to find what we really interested in.

Hello

I have C9J7, I can play Asphalt 8 for 2 hours with no problems, but my WiFi losses connection while sleeping (sometime ).

Did not test Android side of the tablet much, but it works. Got it from KnoDo Ltd. on Aliexpress.

[MENTION=2198172]mirek190[/MENTION] Can your mirek190_rom_v3.0_04.01.2015 be install on dual boot C9J7 system without "damaging" W8.1 and how?

Thanks
[Teclast X98 Air 3G] mirek190:
Very easy . Just instal my rom using flash- system only .XML in my rom files.

Second way :

you can get to droid boot by fastboot command .

Like

When you in Android - connect tablet to PC and use fastboot

Fastboot reboot-bootloader.

In bootloader

Fastboot flash system system.img

System.img must be in the same folder with fastboot.exe

I would not have to worry about partitions for Android or W8?

Does tablet version mater? mine is C9J7.

I have install English language pack, but there is still a lot of Chines writing in log in screen or after update etc.. Any boy alse have same problem?

Bios/Firmware update fail

Hi,

I have an X98 Air C8J7 and I inadvertently flashed with the wrong bios. I selected the wrong bin file. Now when I try to power on I get nothing. I've tried power button + volumes up/down with no luck. Does anyone know of any threads that may exist on this? I really like the tablet and would hate to lose it. If I need to post more information about the issue I would be happy to do so?

Thank you so much
[Teclast X98 Air 3G] grigoris_a:
From switched off press power button once to boot and keep holding vol up key pressed.

If you don't see windows icon it means the USB is not bootable.Try getting into bios and see if the USB drive is detected.

[Teclast X98 Air 3G] Petepe10:
Tweak?

I only have occasional freezes in RR3, never in opengl benchmark. So tweaks are hard to test. Attached two files that I am using now, and seem to help prevent freezes, at least my impression so far. If someone wants to test:

Make backup of the original xml files

Copy attachments to /system/etc

Rename them to xml (extension is now txt, xml is not allowed as attachment)

Set rights to rw/r/r if needed

Reboot

Test...

(Obviously, rooted device is needed... )
[Teclast X98 Air 3G] jubpi12:
Thanks mate, I've flashed and all seems good at first, but I have a really strange issue.

When I create a second user for my wife, second user is not functional, I mean:

There is no launcher ( so screen is in black)

There is no play fix.

There is no posibility to open developer options ( as in main user)

...

I just can move in settings menu, Is like ther is no aplicated all your modifications so is no functional.

Do you know anyway to fix it?? By the way , main user works perfect!!

[MENTION=1167021]Hendrickson[/MENTION]

Hi Hendrickson,

I have my c6j7 preinstalled with windows 8.1 with Bing. When it first arrived, I used it without any problems with 3D games in windows. However, since I changed to dual boot, both in Android and Windows, 3D games freeze after one minutes or so. So I assume that the dual bios causes this issue to my c6j7.

Any change to convert it back to original bios for c6j7. Or should I flash bios for android only, android only is OK for me.

As you have c6j7, do you have the bios bin file for it. Can you please share with me. Thanks

[Teclast X98 Air 3G] MCRHAZ:
Hi I am looking to purchase this tablet and was wondering if Teclast provides software updates...in that they will be upgrading the Android version to 5.0 lollipop. Or if there is a way we can port Android 5.0 whilst still keeping the dual boot function with windows 8.1.
[Teclast X98 Air 3G] mnitstanley:
Forget about Teclast software updates. All they have done so far is to upgrade Android from 4.4.2 to 4.4.4.

You may get one more in the life time of this tablet. So kiss goodbye to Lolipop dreams.

I mean look at their history, they fixed a critical Playstore bug after 2-3 months of plaguing requests.

It is also ironic that they relied on a fix from this forum as the work around. Amazing.

http://www.teclast.com/en/Information/008.html

With regard to porting, I don't believe any non-Chinese guy/group is gonna do that. Kernel Source available in public ?

And even if you get one from the Chinese forum, you can't address the coders due to Language barrier to squish the bugs.

Most of us here still rely on Google Translate to decode those forums.

And if a miracle happens, CyanogenMod or MiUI may release an official ROM for Teclast and the World will end that day :p

Having said all that, that's just my opinion.
[Teclast X98 Air 3G] mnitstanley:
One incident points to Dual Boot BIOS problem because Single Boot BIOS worked OK for the user

BUT Out of the defect-free tablets, majority is Dual Boot.

Another post points to kernel/OS bug because Sony video engine solved it for him. [MENTION=2198172]mirek190[/MENTION] [MENTION=2470600]supercowz[/MENTION] [MENTION=3014815]SUMMERBREEZE[/MENTION] [MENTION=281521]jcespi2005[/MENTION]

Yet another solved the issue with HW tweak to control thermals.

Someone eve tried for a Thermal Algorithm tweak and succeeded partially.

Single BIOS + Windows = :good::good::good:

Single BIOS + Stock Android = :good::(:(

Single BIOS + Custom Android = :good:

Dual Boot+Stock ROM = :good::good::(

Whatever + HW tweak = :good::good::good:

Is it true that HW of

Windows only

model is different from rest of the models. It doesn't have GPS and 3G ?

Anyone spotting a compelling pattern here ? I don't.

Doesn't this mean that it is a plain HW issue with a particular batch ?
[Teclast X98 Air 3G] MCRHAZ:
loll thanks for the detailed response...yeah I guess I was reaching for the red starburst on that one eh...but on the whole how is the tablet to use on a day to day basis, I wanna buy this for my dad who isn't going to be creating many documents on it but simply reading surfing the web and watching movies on youtube or netflix... do you think 4.4.4 is manageable on this device with say the google now launcher? is it laggy? or buttery smooth?
[Teclast X98 Air 3G] mnitstanley:
It is buttery smooth for day to day apps. This device is not laggy in any sense.

4.4.4 is not bad at all. But it is humane to yearn for that extra mile :p

I hope your Dad is not gonna watch 4K videos on this :silly: Is he ?

Most users are so happy with this device because they don't know they have this problem.

Because they dont play heavy games on this. Even moderate games are also OK.

Ignorance is Bliss .. huh ..?

[Teclast X98 Air 3G] smartchip:
OK guys, so I just re-read the bbs.teclast.com post above and it says:

Under Settings / Developer Options - turn on "Force 4x MSAA" (found under Hardware Accelerated Rendering).

Did that and just managed to finished a race in Asphalt 8! Usually mine freezes at the opening animation of a race. I'm gonna keep trying and report back. If you're having freeze issues with 3D games do give it a shot.

Edit: Bummer, it sure took longer to bug out, but it eventually froze on my third race [emoji29]
[Teclast X98 Air 3G] SUMMERBREEZE:
so you are basicly saying, when Force 4x MSAA is off, yout tablet just freeze at the beginning, but when it is on, it took much longer to freeze? so what does Force 4x MSAA thing do?

[Teclast X98 Air 3G] smartchip:
No clue [emoji39] I'm just trying out stuff based on the post in Teclast forum. Besides the post OP saying he's solved the freezing issue, none of the replies confirm the fix.

Edit: OK, I swear I'm not delusional. Turning the option on allows me at least 2 races in Asphalt 8 before it freezes. Turning it off, I can't even get past the opening animation of a race. Same with the Unity benchmark, I complete 1.5 times the benchmark in 1080p with it on. Maybe an option for those who takes breaks between games? [emoji39]
[Teclast X98 Air 3G] mnitstanley:
Completed Unity Benchmark once and it showed 8.08 on screen. Is that the score ? Froze in the second attempt :(

But with Real racing 3, it is still the same. Can't get past the intro video.

Now I am going to test with 3D mark on Windows as well as Android. Shall be sharing the results soon.

3Dmark Android fails. Gets stuck after 1mins 20secs

Is there any way to unroot the device so I can apply the update?
[Teclast X98 Air 3G] Hendrickson:
I flashed my C6J7 with the daul boot bios too, to return to just windows I flashed the Air II bios from here: http://techtablets.com/teclast-x98-air-3g/downloads/

It's basically the same bios as the Air 3G windows model, just that I did not want to risk a software dump so used the Air II bios and it works 100%
[Teclast X98 Air 3G] ApteryxK:
So if i am going to buy the tablet i should buy a windows only version ? What do you recommend ? Aliexepress ?

And what does that mean :BUT Out of the defect-free tablets, majority is Dual Boot.

Does it mean dual boot are defect free or more likely to be defectly.

Any suggestions and advices? :cowboy:

but in the other hand, if this info is really true, then how did they (Teclast) fix the problem? and why they are not putting this information in their website to public?
