[Teclast X98 Air 3G] SUMMERBREEZE:
i just dont want to talk about this problem anymore in this topic, i am sure some people want to see some other helpful things (flashing, rooting, drivers etc etc.) and i am really bored and sick of seeing that people saying the tablet freezes while gaming etc.

people can do what they want. money is theirs.

but i believe i warned people enough. this tablet is not for gaming or 3D stuff, it can freeze even when it gets very hot while watching a film or youtube etc. this is a 200 usd cheap chinese lottery tablet. all is up to you :cool:
[Teclast X98 Air 3G] grigoris_a:
I haven't left it yet overnight but judging from the sleep study reports where most of the seasons where green I would day that I am whithin Microsoft specs for connected standby.Even better then my ThinkPad 8 tablet.
[Teclast X98 Air 3G] mirek190:
I'm not agree with you. Tablet works perfect for gaming as well - I have 3 of them and no freezes at all in games. :)
[Teclast X98 Air 3G] SUMMERBREEZE:
You are very lucky one Mirek :) you have won the chinese lottery :D

and yes i am lieing, i can play every game with no problem!

and Teclast made this announcement just for fun! :good:

WiFi problem

Hi wanting to know if someone can help please, I have two x98 3g air ' and on one them everytime I turn it on I have to put my WiFi code password in everytime the other connects fine, this one doesn't is there a reason why please
[Teclast X98 Air 3G] sence:
This is the reply that I got from the seller for some of my questions

"OK, get you. here are the answer you need:

1) we have test 10% and all running good with 3D games, but there are too many games now and every game is different requirements in resolution, storage, RAM. Just like iphone4 is hard to support IOS7 frequently. So it may not support all 3D games, we have tested real reacing 3, and it is running good. (My qn was about the freezes while playing 3D games.They only test 10% of devices...Looks like they choose only the good ones to test and put the ones with the gpu issue in the "not tested" group :D ....)

2) no, please do not worry, we are out of stock these days and all the item are bought from Teclast few days ago. (My qn was about selling the returned tablets on this $199 sale)

3) this batch is C9J8.

4) emmc brand---i have told our boss to ask supplier, but there is a little slow answer, will let you know once i get news. :)

5) you can leave a note ask for this, and our guys will change to english for you before shipping.

6) we have tested real reacing 3. :) and it runs well. (My qn was about testing my tablet before shipping,if I pay for it.Without even the payment they are saying that they have already tested my unit :laugh: )

Hope all this helps, please consider carefully ( Is he/she really trying to tell me something :silly: ) and make your decision.

jessie"

I cant still make a decision..Please guys, if you guys know a good tablet with screen size 7-8" and has dual boot and a good screen like X98 air, do reply.....I am really thinking of going with the X89 dual boot....I am also wondering,If there is a dual boot model available for X90HD......Still worried about freezing issues even on the above mentioned tablets,while playing 3D games.....If any one saw a good review of X89 dual boot / X90HD model, please share the link...THanks.
[Teclast X98 Air 3G] mirek190:
I didnt tell that you are a lair .

Just said if you have teclast air 3 g without freez problrm the is really good device for gaming.

BTW I have 3 full stabe devices and my friend bought one teclast air 3g as well ( C8J7 ) his teclast is full stable as well.

I don't have any idea how many % of devices are unstable in 3d. But if I have 3 ok devices and my friend as well ....We didn't bought that device cheaper like you for instance. [emoji6]

My Air II runs very well - 3d Games, Benchmarks - no Problem :)
[Teclast X98 Air 3G] muzetas:
In my sleep study raport all positions are green, but the tablet is still draining around 5-7%/h. Over the night it losing the ~60% of power ;/. On android all is perfect only 5% per day on standby.

I think that original windows from Teclast may have working properly standby. I installed windows pro from .iso and injected the drivers and maybe this is the problem...
[Teclast X98 Air 3G] SUMMERBREEZE:
so you mean, the seller send some of the defected or returned ones to people in promotion days? :crying:

kind of clearness :D not fair.. i am not also saying all the tablets will have this problem but we can not just guarantee for everyone.. I also dont know how many % of the tablets are like this but the seller had told me that so many people is asking them about this gpu problem.. and in here XDA, i saw a lot of people still has this. this is not a little amount IMO.. and Teclast made even an official announcement in website, if there was really little people who had this problem, i dont think that Teclast would make such thing. BTW, i am happy for the people who has a stable tablet, including you, i dont have anything against you but you must also understand us. Its not easy to see such behaviours from the sellers and they still keep telling lies. :crying:

---------- Post added at 10:42 PM ---------- Previous post was at 10:40 PM ----------

This topis is not Air II topic, also i didnt hear bad comments about Air II before (about GPU issue).. maybe it has got a different PCB and architecture i dont know. but i am happy for you aswell mate.. I dont think i did something wrong here, i just wanted to warn the people and be careful, after payment, contact the seller and ask the stable one :) thats it :good:
[Teclast X98 Air 3G] muzetas:
They also said that they checked my tablet and I got defective one. Before the shipping I sent them a 3D benchamark test. Don't belive them.
[Teclast X98 Air 3G] Maringer:
Aeroplane mode switches off all wireless connections. This includes wifi and bluetooth so you are left with an unconnected tablet. Not much use.

I just want to be able to switch off the mobile network connections.

I do seem to have an issue with my tablet which I'm not sure has been mentioned in this monster thread. It seems to randomly freeze when sleeping unused and the only way to get it started again is the long 10 second power-off before switching back on. Sometimes, I even need to charge it once again before powering on!

I'd imagine this is a software issue so I may have to try Mirek's ROM to see if that improves matters. Using the Google Now launcher which I suppose might also be an issue?
[Teclast X98 Air 3G] smartchip:
1. Turn on Airplane Mode

2. Turn on Wi-Fi

If it works as it should, you should see the Wi-Fi connected with the Airplane icon in the status bar. 3G radio and data should be off.

It didn't bother me, but I did notice that my tablet randomly restarts while I'm not using it or when it was on the charger. Didn't have to power-cycle it though, may be a different issue.

Personally, I like the Google Now launcher, but it doesn't play nice on some devices like my Samsung tablets. Try Nova launcher, works with everything I've thrown it on.
[Teclast X98 Air 3G] majkel_94:
Airplane mode turns off wifi, BT and mobile but it doesn't disable it.

You can turn on airplane mode and then just turn on BT or wifi, I have this all the time because I use 3G only a few times a month :P

[Teclast X98 Air 3G] Maringer:
Thanks guys. I would say I didn't know you could use wifi in aeroplane mode, but I have a feeling I had read this elsewhere in the past but had forgotten!

I'll try another launcher as well.
[Teclast X98 Air 3G] SUMMERBREEZE:
this was what i wanted to ment, thank you for the explanation. even there is NO sim in the tablet but 3G is ON, it eats a lot of battery
[Teclast X98 Air 3G] grigoris_a:
I find this impossible.In study report you have the first table that shows every session above 10min that tablet slept.In the tables that follow you have the analysis of each season.If in the first table you have all green it means your tablet looses less then 2% per hour.Maybe you mean in the tables bellow of the first are all green(that shows the possible offenders)

When I had dual bios I was also loosing 5-7% per hour and I tried Teclasts and pro windows with no change.

Regarding the tweak for improving temperature in the cpu....besides [MENTION=4777359]acc007[/MENTION], anyone tried? Just in case it can improve the freezing issue a bit at least, although for him, it didn't work.

Besides, anyone with C9J8 have checked if in their official dual boot bios, you have the turbo disabling option? If so, could that Bios be "exported" somehow and then imported to previous versions?

By the way, where can you get the components used by acc007?

Thank you everybody!
[Teclast X98 Air 3G] Frontier:
A small tip: root the tablet after all official updates are installed. Official updates always un-root the OS.

I've learned it from my OnePlus One ;)

Enjoy.

[Teclast X98 Air 3G] SUMMERBREEZE:
a very dummy question, i didnt get my tablet yet, so it will come with older Android version, to do install this new one, what way or tool do i need? Or it will be available for downloading from OTA?

thank you

---------- Post added at 02:34 PM ---------- Previous post was at 02:28 PM ----------

we should also keep forcing the Teclast with our emails etc. then they will maybe work harder and faster :) as i can see , it is the most popular tablet at aliexpress right now. So so many people already bought it or still buying.

Hi,

I've just updated the post number 2 with link to ADB Driver, GOOGLE PLAY STORE FIX and KITKAT 4.4.4 ROM(OFFICIAL) v2.0.0.

Could anyone check if with new ROM version the multi user mode work correctly,please?

For verify if all is ok, you can try to create another user from main user session and switch to the new user profile. When you are logged as new user you can try to add an existing google account,in the 4.2.2 version the keyboard seems not work.

I would like to thank all those who contribute to improving this thread, a special thanks to Frontier and BoORDeL for their suggestions.

I think that better the quality of instruction and tutorials are, less problems or troubles will we have.
[Teclast X98 Air 3G] SUMMERBREEZE:
i thank you for making a great thread to help to all of us :good:
[Teclast X98 Air 3G] Frontier:
In order to install this version, please use the guide "Windows to Android" described in the second message of this thread.

Just ignore the part about the Android DnX BIOS as it is not needed.

You can also find the necessary flash tools there.

I've done what you've described and still the AOSP keyboard does not work because it is not selected by default.

It is very easy to fix however: after the new user logs to the OS, go to Settings > Language and settings and just click on the AOSP keyboard settings icon (the one on the right side). Just change any option there (e.g language, offensive words e.tc) and the keyboard will work correctly.

This bug appears when the main user (the 'owner' of the tablet) does not use the built-in AOSP keyboard when the new user is created (I used Swype while creating the new user). Since the new user does not inhere the keyboards/settings the owner has, the new user is created without a default keyboard selected.

Quite silly but luckily easy to fix.

Enjoy.
[Teclast X98 Air 3G] francescoliberti:
Hi,

I just bought the tablet, and I want to switch from Android to Windows, following the guide in the first post.

I would ask only one thing: when I load windows, the tablet works perfectly? There are particular bug, for example, do not work or work badly camera, microHDMI output, GPS or 3G consumes more battery?

thanks
[Teclast X98 Air 3G] SUMMERBREEZE:
these are the most popular bugs in the topic

1) camera is inverted. if you want to take a photo of a friend, you will see his head is upside down :D but some 3rd party softwares like ManyCam pro etc. can fix this issue.

2) screen refresh frequency is locked to 48 hz, should be 60 hz but not, i think its a gpu driver issue. we are also waiting a fix for this too

apart from that, its almost stable in windows
[Teclast X98 Air 3G] jcespi2005:
microHDMI and sound

Does anyone here tested the microHDMI connection?

Tested with the cable shipped with the tablet, and works fine in my fullHD TV, but no sound trough HDMI connection. Seems there is no option to enable the HDMI output for the sound. I have a Minix X7 and has options in sound to enable HDMI and other options for the sound.

Any ideas?

Perhaps is a good idea to report to teclast to see if they can enable it...

Cheers
[Teclast X98 Air 3G] BoORDeL:
as stated before hdmi works fine, video and audio.

Have you got at least v 1.4 hdmi cable?
[Teclast X98 Air 3G] Frontier:
Yes works fine, no issues at all.

The X98 Air 3G does not ship with an HDMI cable, only with an OTG cable and the USB charging/data cable.

Anything else was probably provided by your seller and it could be possible that the cable supplied is incompatible.

The X98 Air 3G like all Baytrail platforms require an HDMI v1.3 cable (at least).

I am using the X98 together with a plain HDMI v1.4 cable and the necessary converter for micro HDMI, no issues whatsoever; sound is enabled and the only options are - by using the VOL- and VOL+ buttons - to either have it on or off (i.e no volume adjustment on tablet).

Try another cable, nothing wrong with HDMI using ROM v2.01.
[Teclast X98 Air 3G] jcespi2005:
Thanks, both...

Tha cable was part of a seller bundle, so i'll claim him for a working cable.

Cheers
[Teclast X98 Air 3G] mitsos1os:
Hi guys... I also have the tablet and i am really satisfied with it on Android. I was thinking about flashing to Windows, but I saw that the windows firmware is in beta, and somewhat buggy with things like inverted camera etc... Also it is very annoying that the official forum is only in chinese, with Google Translate almost useless in some cases... Glad to see that there is a community forming up here for international users...

Anyway, I would like to know if someone could point, if except for the dual boot systems that are making a fuzz, there is a stable windows only firmware with the camera invertion resolved for use with apps like Skype etc.. and generally stable.

Thanks...

I found this thread which was posted just a couple hours ago on how to install the new IFWI BIOS.

The Android 4.4.4 download is on this thread:

http://bbs.teclast.com/thread-257530-1-1.html

http://pan.baidu.com/s/1sj0RN1j

Password：36z1

The new IFWI BIOS is posted here:

http://bbs.teclast.com/thread-257708-1-1.html

Link: http://pan.baidu.com/s/1hq69Nco

Password: 95z4

Okay I realised the thread is in Chinese and full of JPEGS which can't be Google translated, so I had to do it manually, below is my translation...

Changes:

1) Upgrade Android SDK from 4.4.2 to 4.4.4

2) Improve functionality and increase generally stability of the system

3) Update built-in APK procedures

Update of the IFWI fixes:

4) Video playback crashing

5) Improve Wifi related parameters

<<start of JPEG>>

Gentle reminder:

1) Carefully read the instructions before doing anything

2) Before updating IFWI, ensure at least 50% battery power

3) While updating IFWI, do not run other apps simultaneously

4) While flashing IFWI, NEVER force shut down

5) Flashing IFWI has its risks, please practice with caution

6) This version of IFWI improves Wifi and crashes

Preparation:

1) Download tools for flashing IFWI: http://www.teclast.com/tools/pad/pad.php

2) Prepare a USB keyboard

<<end of 1st JPEG>>

<<Remaining JPEGs>>

Actual flashing proccess:

After extracting the IFWI firmware and the tools, copy the contents into the tablet’s internal memory as show in the picture.

From the tablet, open a file explorer, navigate to the corresponding directory and run the “UpdateIFWI.apk” application.

In the application, there is an option to select the BIOS file, select the “Rom_8MB_Tablet_Android.bin” file.

After that, hit the update button below. Update will proceed and system will restart after it is done. At any time in this process, NEVER force shut down the tablet.

On an unrelated note, here's a leaked picture of the X98 Air 3G doing TRUE dual boot Windows and Android that's being tested by the engineers...

[Teclast X98 Air 3G] FEGuy:
Big thanks to whoever did the TF2 test. Absolutely buying at this point, but a couple last questions anyways:

- Given the name and stated dimensions of the tablet, has anyone tested how well it fits to iPad Air accessories, etc.?

- Has anyone gotten any form of Linux (I know there's Fedlet for Bay Trail tablets, but I'm not sure if it'd work with the way X98 OS installations seem to work) running at all? I imagine there's not much that'd make it worthwhile for everyday use, but I have a Unix/Linux Systems Administration class next semester and I'm running out of ways to piss off this particular professor.
[Teclast X98 Air 3G] SuperRockmen:
Hi guys, so which tablet is better? The air 3g or the air ii? I am primarily using it for videos and playing some games. Also is having dual boot worth it? ( due to the space partition and so) appreciate any comments thks!

This is what i got as a message this morning from the seller OKQI

I will not comment.
[Teclast X98 Air 3G] 84.hp.bluestacks:
haha.....you think they are so free to test all the tablet.....no way.....random test maybe

the postage from our end to China is so much expansive compare to them....

so far from my site:

1 good x98 air 3g

3 good x98 air ii

1 good x98 air

1 bad x98 air

buying China tablet always depend on your luck...........
[Teclast X98 Air 3G] SUMMERBREEZE:
of course they can not test each tablet, but i believe that they can test the tablets if the buyer deffinately asks.

They can also contact with Teclast and press them to be more careful about production and quality check. I dont think they do even one of them. They also say that they tested the tablet and it is stable but still ship the defected one :silly:
[Teclast X98 Air 3G] smartchip:
Your statistics give me some hope that my replacement tablet will not be a bad one. *fingers-crossed* Perhaps the ratio of defective vs. good tablets is not so bad.
[Teclast X98 Air 3G] mnitstanley:
It could be true. They have to maintain their reputation after all. But testing and shipping 2000 tablets they sold on 8th Jan is going to take some time.

Clearly it is a hardware fault. The 8th Jan models tablets could even be the reworked pieces.

So are you going to open a dispute for your piece and appeal for partial refund because sending back is going to leave with a net loss ?

Also I support your view regarding escalation of the issue through feedback. It is just that the lucky ones never really understand the unlucky ones. It's plain human nature. You don't look back once you get lucky. And also so unfortunate to see argument like "we didn't buy it cheap unlike you" from a logical person. So insensitive. I didn't buy it on 11/11 sale and I have C9J7 and still got a defective one. It simply blows away that argument.

Testing each tablet before shipping is not a big issue especially when they have to open & install the English language pack in Windows. I received it that way. You just happened to be lucky to have so many good devices.
[Teclast X98 Air 3G] SUMMERBREEZE:
thanks a lot for your understanding :) i had opened the dispute before and was waiting for them to give me a solution but nothing psitive happened. so i will ask maybe 60-70 usd partial refund and see what they will do..

And also there is something else, this device sold by some other companies on ALIEXPRESS. Its 196-204 USD (single boot version) and we all know that we can convert the C6J6 and C8J7 to dual boot one easily.. maybe we can ask some more discount from the seller (reducing the price if we all buy from the same seller) and also ask detailed test.. since they are not that busy like OKQI, i think it wont be that much problem for them.. I will contact with some of them and let everyone know here :)
[Teclast X98 Air 3G] mnitstanley:
I may believe them this time. Look at this turn of events (suspected)

Sells C6J6 and returns some as defective mainly Playstore. Didn't take it seriously.

Sells C8J7 and still same issue. Unofficial fix for playstore available but now 3D issues come to fore.

Sells C9J7 upon Teclast promise of issue resolved. Sees playstore issue fixed and still ignores 3D issue but OKQI pressurizes teclast to release fix for previous models

Sells C9J8 upon promise that all issues resolved but still complaints

Sends back remaining C9J7 and C9J8 stock to be fixed

Teclast does HW rework because no Bios change in working C9J8

Sells all reworked models on 8th Jan after testing every single piece.

Sorry guys I just don't have any other option than being optimistic here.

---------- Post added at 09:25 PM ---------- Previous post was at 09:15 PM ----------

You can't blame the sellers or even Teclast for not having play store working. It is a Chinese government regulation against having some Google apps installed in devices sold in the Chinese market (which this device is primarily made for)

Also reading other forums it seems a lot of other Chinese brands (Onda etc)have the same problems with the same games as these tablets.
