[Teclast X98 Air 3G] heartbr:
I am going to repeat my previous post so It doesn´t get lost in the jungle of posts:

I own a teclast x98 air 3g.

I installed the dual boot, and android and windows.

It happens to me that when I switch off the tablet from android, I can switch it back on ok.

But when it is switched off from windows, it cannot be switched on just by pressing the botton as usual. I need to do a long-press to reset the tablet, and then it starts fine.

It is more than one case that I know this happens and we have no clue what it can be.

Can you help?
[Teclast X98 Air 3G] PESCEPALLA:
I have just received the teclast x98air 3g dual boot from Geekbuying, the seals they were broken therefore surely they have put the hands on it.

android in English, completely Chinese windows but above all after two or three touches it begins to dance and freeze. I must re-send back immediately it?

The procedure more simple to eliminate the Chinese version?

and because' they write that all the languages are supported if it is not this way?

as you will have understood it is my first Chinese tablet, I ask all of your polite suggestions, you are indulgent

thanks

Was wondering if anyone could help me. Whenever I plug my air 3g into charge, it doesn't really heat up, although the charger itself gets almost too hot to touch after about 30 mins. When I unplug it, it immediately smells like its been burnt.

I've used various cables/chargers all with the same result.

Charging via computer is fine (but very slow).

Is it possible to fix this?
[Teclast X98 Air 3G] juaaslo:
I am sorry, that doesn't happen to me, using provided charger by teclast which outputs high charge.

Anyway, it is very weird it is a not an increasing problem. I mean, in case you had problems with battery or charger, you should notice one of them getting hottter and hotter when you plug it on, not just cool during the whole process and all of the sudden, you switch off and something gets burnt.

I am charging mine right now and it is totally cold. Have you tried in another plug? What is what gets hot when you unplug, charger or teclast? Where is the smell coming from? Does it dissapear inmediatly?

BR

PS: I have noticed it is a pain in the ass to leave it charged, since no led to inform when it is charged, and no image on the screen informing about battery charging.
[Teclast X98 Air 3G] ImJamIN:
Hi mirek,

Have you tested microphone?I think that the fix with new Base isn't working so well. It make a conversation too loud.

[MENTION=2198172]mirek190[/MENTION]

I flashed your rom system only, and I noticed that there is no more power off option only reboot, Why so? Is there another way to shut down the tablet because I don't want to have to power cycle the tablet each time I want to shut it down

Also without the option key I can no longer access options such as sound effect, search and party shuffle in the default music player though that's no bigger because the default music player sucks and has a terrible ui, so could you change the music app in future releases
[Teclast X98 Air 3G] KyeMillington:
What I mean is, when I take it out, If I bring the charger to my nose it smells like it is burning, along with the part of the usb cable thats inserted to the charger. The charger itself gets hot when I put the tablet on charge, it gets so hot it has that kind of smell.

It disappears after about 5 minutes, but stays hot for about 30 mins when unplugged.

Hi,

I am trying to install dual boot on my X98 Air II. i succesfully installed the bios, but after i installed IntelAndroidDrvSetupx.xxexe. my tablet is still not recognised by the PC. So i could not able to install Android, but my original Windows is still intact and usable. please advise guys
[Teclast X98 Air 3G] djeskoswe:
I have no options in my bios to change turbo , i looks like a locked bios.
[Teclast X98 Air 3G] acc007:
On 11th Nov and earlier I bought some pendrives and micro sd cards from aliexpress and after verifying with h2testw the only 2 recommended items from my experience are:

1) micro sd 32 gb, real class 10, real capacity: http://www.aliexpress.com/item/Best...manufacturer-Free-adapter-free/508253716.html

2) micro sd 32 gb, real class 10, real capacity: http://www.aliexpress.com/item/Micr...rd-2GB-4GB-8GB-16GB-32GB-64GB/1237877283.html

I also bought some pendrives for kids, also 32 gb, and these very real fakes... I got 100% refund for them, so DO NOT buy them:

1) http://www.aliexpress.com/item/Reta...drive-memory-stick-u-disk-for/1585751018.html

2) http://www.aliexpress.com/snapshot/6330465775.html?orderId=64491798612442

What is funny... real class 10 cards are having read speeds ca 15mb/s, while fake pendrives have only ca 1.2mb/s read! Yes, over 10 times slower!
[Teclast X98 Air 3G] mirek190:
Sound efect are in viper FX even equaliser - look there.

Swith off tablet you say ? Just keep power button for 6 sec or so to swith off completely .
[Teclast X98 Air 3G] acc007:
Well, the materials... I had copper plate and artic silver 5 paste at home. The only thing I bought was a thermal pad, I bought it on local auction portal: http://allegro.pl/termopad-termopady-thermopad-200x20x0-5mm-3-8w-mk-i4976172231.html

But as for the results... yes, it didn't help much. Lately I switched back to Android only rom (official from teclast), and turned off turbo and so on according to the screenshots attached somewhere in this thread. And it helped a lot - I was able to run unity benchmark 5 or 6 times in series, then play a few minutes of asphalt 8 and then a few more minutes of real racing 3. CPU temp reached 43 deg C max.

BUT... after few more days... it isn't so perfect. When my daughter plays my tablet (she loves "my talking angela" which is not so gpu intensive game) for example for 2 hours without proper ventilation, the tablet reaches ca 48 deg. And if we play rr 3 then, it will play only for a while, and then - freeze.

Someone mentioned angry birds transformers. I didn't play it, but I confirm that my tablet freezes with Angry Birds Go (when it is warm). I can play it a lot in the morning, when tablet is cold after the night, but when it is warm it gets freezed in a short time. Still with turbo off...
[Teclast X98 Air 3G] juaaslo:
Thanks for answering,

I agree, when I just start tablet, I can load games and they freeze a few seconds later. If I have been using the tablet before, it is inmediate. Si I think I am gonna follow your tuto in case something improves, even a little. You confirm a decrease of 10º which is a lot!!!

I red after using thermal pad and cupper, there was some space left to close the tablet. Do you think I should get 0.5mm or 1mm thermal pad and cupper?

Thank you so much
[Teclast X98 Air 3G] acc007:
I think it is safe to use 0.5mm thermo pad between display and pcb, 0.5mm copper between SOC and SOC shield and 1mm thermopad between SOC shield and back case. This is my current configuration (however between shield and back case I have 2 0.5mm thermopads stacked, so it gives a total of 1mm).
[Teclast X98 Air 3G] arthurdub:
The wall plug part of the charger gets hot but mine shuts off when the tablet is fully charged which is good because some chargers keep running hot until you unplug them. I also noticed that the tablet also charges faster out of a certain wall outlet in my office (must be a higher voltage). The video star hendrickson picked up one of these multiport chargers if you you are worried about it.

WIDI / Miracast feature (working dongle)

Hi guys,

I am very curious about wireless display feature in Windows (WIDI / Miracast).

I have found a problem - I downloaded Intel's WIDI Update Tool from page:

http://supportkb.intel.com/wireless...fservice/intelwidi/#portal/1026/article/16168

and I have this error:

Your system has an Intel Wi-Fi adapter that is not supported by this update tool.

The WiDi Update Tool does not support the Graphics adapter installed in your System.

I am very confused - this tablet is touted as WiDi compatible, but official WiDi tool (Intel) returns an error...

I am not sure if I have some drivers mismatch or is it a hardware issue.

Could you guys please check your tablets by this Intel tool (you can download it by above link - very light, only 649 KB).

Second question: can anybody recommend me (and to others) any working WiDi / Miracast receiver which will work with this tablet (on Windows)? Unfortunately I do not have this feature build-in into my TV so I need to buy some dongle (receiver).

Thanks in advance!
[Teclast X98 Air 3G] KyeMillington:
Thanks mate, I'll look into it.

Never realised it turned itself off, that gives a greater piece of mind.

[Teclast X98 Air 3G] fred7106:
I am one that have a C8J7 "bad" tablet, however I bought it on 11.11 with a good discount and the USD low respect the Euro, now Anna Fong gives to me the opportunity to replace the tablet, but this mean at least 25 Euro for to ship back (they want tracking) and to the same time you must have confidence that you receive back the tablet and this one is a good one.

So my opinion is to continue with this one because (if we don't want play games) with the dual boot the tablet is very good expecially for the price that we have invested : phone, retina, dual OS.

I have also the Onda V989 with A80T little e big, the quality is the same, you can play games and the tablet is very fast, but it has not 3G e GPS and it is no possible to install windows.
[Teclast X98 Air 3G] codezion:
Call me crazy but I think I am going to go ahead and buy this tablet. Hopefully I get one without the gaming issues. If not, I can live without heavy gaming on tablet. From what I have read, it is fine with respect to everything else.

Just curious though... did anyone have to pay extra fees if the tablet was shipped via DHL? I'm wondering if I should do standard post to avoid surprises or expedite using DHL.

Thanks.
[Teclast X98 Air 3G] Nuja:
im waiting for 2 teclast x98 air 3g dual (ordered from tinydeal in early january), hope i get good one, atleast good enough to do anything not related to 3d without freeze ^^
[Teclast X98 Air 3G] legalchiz:
A Big Thanks

I was trolling this board and eventually purchased an x98 Air II online. Received a dual-boot HG7N, and I love it. So far no apparent crashes, etc. It does "thermal throttling" pretty easily and there are some other quirks (haven't yet had the courage to install a custom rom to get rid of the bloatware), but very happy with the purchase. I wouldn't have gotten it if it weren't for this thread and the hard work of people like the OP and Hendrickson. So: thanks. :good:
[Teclast X98 Air 3G] craigg123:
Depends what the seller declares the value as. Mine was declared as $25 communication device. It has arrived in my country (was sent on Wednesday), DHL says it will be delivered on Monday and best of all $0 tax or othe fees as it's a "low value package". Could be different in your country though.
[Teclast X98 Air 3G] cyber2rnk:
Received my C9J8 model yesterday and so far so good. Testing it on Android and no issues so far will switch to Windows soon. Check battery backup below on continuous use on WIFI and 2G from full charge. How is it others??
[Teclast X98 Air 3G] Cozla:
Beside freezing issue I have problem with tablet case, it seems not fit well. When I press the tablet it creaking. Whatch and listen to this [YOUTUBE]http://youtu.be/Md1Vrmvf5m8[/YOUTUBE]
[Teclast X98 Air 3G] SUMMERBREEZE:
Have you played any game in Android? for example Real Racing 3 and Asphalt 8?

I am asking because some of tablets gets freeze while gaming
[Teclast X98 Air 3G] renton82:
I have the Air II version but i had the same problem, i have just tried your trick and i hope it will work for me too! I'll report back!

Using no app partition how is possible to move app on SD, taking in account that now for the dual boot we have reduced the space data of the android partition?

Thanks
[Teclast X98 Air 3G] thehobit:
Thanks for the new ROM. On a new C9J7 dual boot, if flashing only system.img and boot.img

1. Would it override the dual boot or only affect the android?

2. Would it eliminate all the Chinese apps at once, or apps are intact as mentioned in the post?
[Teclast X98 Air 3G] juaaslo:
Real time help :)

Hi all,

I need real time help, although I think I am already screwed :S

In order to try different things, I installed last ROM from [MENTION=2198172]mirek190[/MENTION] and then I pretended to change BIOS from current Dual Boot Bios for C8J7 to the one in the first post from [MENTION=277859]Frontier[/MENTION]: X98 Air 3G Android BIOS 4.4.4 (IFWI) (http://d-h.st/7OC)

Well, I thought I wouldn't have any problem installing IFWI and then trying to upgrade the BIOS, but it is "upgrading" since 25 minutes ago and it keeps saying "Upgrading, this may take a few minutes...."

So I guess I am screwed, but any idea about a way to avoid bricking before forcing the tablet to shut down? Any ideas?

Thanks in advance!

BR

EDIT: No brick after all. I closed the IFWI and restarted device, and working as expected. Anyway, I think this is a question for [MENTION=2198172]mirek190[/MENTION]: If android version is 4.4.4, why is not working IFWI to change BIOS? How can I go back from Dual Boot BIOS to latest Android BIOS?

Thanks
[Teclast X98 Air 3G] mikbe:
Am I blind or is there a shut down option missing in your newest ROM [MENTION=2198172]mirek190[/MENTION] ?
[Teclast X98 Air 3G] sence:
Hi, I think its not a problem with your tablet...Intel's WIDI is older compared to miracast, eventhough people call it WIDI/miracast.....For the windows8.1,we dont need to install anything....Miracast is integrated into the OS....Just swipe from the right and get the charms menu....Then follow this , Devices-project-Add a wireless display....It will search for available miracast adapters or miracast enabled TV/monitors.....But I love WIDI, 'cause in that we can stream the screen at 60hz....miracast only supports upto 30hz on the tv/monitor....And forget about gaming via miracast 'cause response time is like 100ms....

About miracast/WIDI adapters, I use the NETGEAR PTV3000 and its good...It has got dual band support- 2.4 GHz or 5 GHz....Ignore the negative reviews on this device...After the latest firmware updates, its working perfectly...
[Teclast X98 Air 3G] antony84:
People, seems i can request order cancellation yet form my abiexpress account. Do you know there is a penalty to pay?

What you advise me? Better avoid the chinese lottery?

I would buy a windows tablet, but i can't find nothing as good as this one at the same price. Have you some advice for me?
[Teclast X98 Air 3G] juaaslo:
I just use notification toggle for android, so you can select switches for anything in the tablet, including a power menu, in case it can not be found in the rom by itself.

Tethered CWM for Teclast X98 Air 3G works

Thanks to bodivas. He provided a modified / working version. See the link above. It works without any

modification.

This is what I tested already:

1) Backup to external SD card using CWM

2) Flashed original manufacturer firmware (boot, recovery, system, ...) 2.02 (C8J7) (all data was erased))

3) Restored just data (not system) from external SD card using CWM advanced restore

best,

gnegne
[Teclast X98 Air 3G] mikbe:
I know and that's how I've been shutting it down. 5-6 seconds isn't enough. :P
[Teclast X98 Air 3G] gnegne:
Hi,

I have some similar problem I just updated my firmware by flashing 2.02 (C8J7). After that I also wanted to update

the bios (android only). UpdateIFWI does not finish. After reboot the "version number" is still the same: "3G068i 1.01 x64" should

be "tpad 1.03" what I read in this thread.

After that I copied /system/bin/fpt-tools-package to /data/tmp/ and called

./FPT -Y -F bios.bin

via adb shell. This is more or less what X98 Toolbox does. There is no

real error message except that a module "iqvandroid.ko" cannot be opened.

I had tested miracast on this tablet, I have installed trial program AirServer for Windows which allow me to make a Miracast receiver from this tablet.

I mirrored screen from my Android phone, everything works perfect, no additional drivers.

If you want to send screen to TV, just open charm bar and look for wireless display option.
[Teclast X98 Air 3G] mirek190:
Later I'll try to add power off button to power menu.

But for now you can just keep power button longer to switch off the tablet completely
[Teclast X98 Air 3G] Akitoyo:
As I read this freeze problem might be because of high temperatures inside the tablet, wouldn't it be possible to go outside/to a colder place and see if the tablet works longer there? I don't expect that it will work perfectly fine, but maybe you are able to play for a little bit longer. Monitoring the CPU/GPU temperature would be useful as well.

btw I just wrote the support an email asking if they made any progress on the 3D issue. Anyway, I don't expect an (useful) reply.

Wondering if anyone can help me out. I have an x98 air 3g windows only version (C6J7). I am trying to do a fresh install of Windows 8.1 pro. I can boot from the USB drive fine and select the partion to install windows, but one it starts the process I get a message saying somthing like "missing files" and then the installation aborts. I tried a few different downloads of window 8.1 pro (Including the one linked in the op). I just want to install a 100% English version and I have a spare pro key that I can use.

x98 user to be..

I'm one of the 8th jan qkqi buyer.Will report later. By the way, I'm not really into gaming but only casual games, rarely. I'll using x98 as windows during office hours & android the rest. Get it because my laptop battery just died, make it unportable. I'm also love the steve jobs's screen proportion (9.7" 4:3) rather than wide screen for tablet & the size just fine & nice to bring around.

So far qkqi promise to test the device (& change the language), at least they do it on android i will belived they test it. so far I'm not pushing them hard, my 1st priority is get the device out from their shop. But anyway i will get ready & expecting to get bad product & get long way (& long time?) to solve with seller, even change the product (x16hd/x10hd?).

It's been a long time I'm not going to xda, since i'm using windows phone (lumia 1520). I'm also have asus tab (use by my kids, along with ipad -sigh, kids these days) that not really developing supported, only half baked root.

I belive the freezing issue so magnified because of the unlucky owner come here to solve the issues. most user that get fine product, don't even care about rooting their android, as long can install fb, not coming here to tell about their device (btw, if you just want to use android, why bough x86/64 system, why not simply get the arm system, that promise 60000 antutu score?). But then, i can say this product is fast clumsy developed, low manifacturing cost oriented & bad qc, that rise the flaw product number come to user. but thanks anyway, new buyer will aware, testing their device & trying to solve with seller, not simply keeping their device & get cranky.

I hope this system actively developed (me myself not a developer) so that this device can be customize & optimize, along with issues fixing (beside keep me busy, haha..)
[Teclast X98 Air 3G] HDtracer:
Just doing a backup now and seems to work very well.

Will try some zips etc and see how they go.

I wonder if this would be an easy conversion to actually flash onto the device?

Oh and did you use T3 to launch the application?

Edit

Any idea where it saves the backup to?

I have been everywhere in the tablet and cannot find it.

Hi. I have installed dual boot android light rom and win 8.1 pro but I have a problem. I can't rotate screen on both OS. On android it just doesn't rotate even I have auto-roration on. On windows there is some problem in device manager 2 devices have exclamation (2 sensor devices). I've tried several times to reinstal drivers from drivers pack but it didn't help. How can I fix it, any advice?

Before I transformed my single android tablet with 3d games issue into dual boot, auto-rotation worked fine.

I searched this thread for solution but I found nothing, sorry if I missed it. I'm new here, hi :)
