I backed up and edited the build.prop file using the APP Build Prop Editor from JRummy.

This dis not solved the issue.

I suppose I need to flash the proper BIOS too, the matter is...I cannot find the file on teclast website. I even need to access the site via a proxy (my-own proxy on google appspot) cause going straight with my internet provider...it takes ages to load the pages (on a 80Mbit fiber intenet connection....)

If you could just provide me the proper link to BIOS downlaod on Teclast website......

tap to wake

Hi, can we add "tap to wake" fonction on Android.?
[Teclast X98 Air 3G] ice.man:
I'm not sure of my bios version:

1st time I checked, it was reported to be C8J7

but I was running a preinstalled modded rom from ecommece website eToTalk

then I played a little with tool-box, intalled new rom

2nt Bios it was then reported to be C6J6

3rd then I just editied a file and NOW the reported Bios is C8J7

As i can see, the bios reported from Android is not the actual Bios, ad far a just editing a file you can force the Os to report a different BIOS

So maybe I never flashed the bios, just changed the reported because o a different ROM??!?!?

How can I know the actual bios version?!?!?

Hey guys,

I want to install a working regular android firmware - no more windows and only android - but there seems to be no chance... I installed the three ROMs given in this thread (chinese lite, supercowz, jcespi2005 - where have these been published? Is there a link to the developer threads?) but I encounter numerous problems with them. I can not find more information on these ROMs and I'm getting quite frustrated.

I have the C8J7 and I can not find a ROM for it. Not even the factory one. The Firmware link in the second post does not work, and I have no idea how to get this freaking tablet to funktion normally again. I should have left it how it came out of the box...

Can someone please point me in the right direction?
[Teclast X98 Air 3G] whymoo:
The tablet supports

2G network GSM 850 / 900 / 1800 / 1900

3G network W-CDMA 900 / 2100

T-Mobile supports

2G network GSM 850 / 1900

3G networks W-CDMA 850 / 1700+2100 / 1900

As you see I shouldn't have 3g ( there is no coverage here for it anyway) but I should have 2g, call, text, USSD, alerts and emergency calls.

Batterylife with Android?

after having flashed immediately to W8.1 and experiencing rather regular battery life I am wondering about yours with Android?
[Teclast X98 Air 3G] ImJamIN:
Thank you very much.

I have find the mode to flash bios dumb via sw without brick tablet.

Now I have Flash c9j7 bios on a c8j7 and it's all right.

I have done all of this hoping to have a bios with more functions but unfortunately it doesn't have it.

It's the same of dual bios from Chinese man.

Thanks to all that help me sending their dumbed bios
[Teclast X98 Air 3G] Hendrickson:
Your battery is not calibrated now, Windows is detecting only one battery cell of the two for some reason. Try to full discharge the tablet and then leave it overnight charging.

Also install battery meter pro and see if the battery is 14000 or 31000 odd in size. If it reports 14k it's defiantly reading only one cell.
[Teclast X98 Air 3G] acc007:

Battery drain

I have the same problem. Battery drain is 2-7%/h

I'm using android or shutting down my tab to save the power.

The battery stats pro is detecting two battery cells, so it isn't that issue.

I found some informations that intel drivers can cause that problems, but nothing more ;/

Guys did you find any solution for that?
[Teclast X98 Air 3G] vgiozo:
Yes, I got this issue too, sadly, after the tablet wouldn't power on for some reason while left in idle....managed to get it to power on again, had to press the power button for around 20seconds, but now it only reads 14mWh battery capacity

Also, according to my battery report, the recognized battery capacity had already decreased slightly during 2 weeks of use, from 31mWh to 29mWh before the aforementioned issue occurred.

http://www.mediafire.com/download/a6655k6bjwa9e54/battery-report.html

Would be great if a solution was found....

are you sure it is just software and not a battery issue per se?

I have communicated this problem to the Aliexpress Teclast retailer, just in case they are familiar with it, but maybe we should make it known to Teclast directly.

Anybody speaking Chinese who can post this issue on the Teclast forum?

[Teclast X98 Air 3G] ImJamIN:
After much test (because every dumbed bios has different code :eek: :confused: )

the most important thing that must be change is the same thing that have tell the Chinese man: 400d and e to FF.

The other code isn't so much important because it change at first boot.

I haven't still install windows, but on android I haven't any excessive battery drain.

Can you upload the bios you flashed to test it??

Have you seen this http://bbs.teclast.com/forum.php?mod=viewthread&tid=260820 ??There is a comparison of an original c9j7 bios.
[Teclast X98 Air 3G] whymoo:
Actually you might be right, I just checked on Fibocom's (modem manufacterer) webiste and with imeidata.net and it looks like it only supports GSM 1800 / 900 which aren't supported by t-mobile. I guess futuremark and all the sellers have the wrong specs. I wonder if it would be possible to change the radio since there are too models of the fibocom H350 and they both have the same specs but differen't frequncies but it is unlikely that fibocom will sell single units wihtout some social enginering.

Google Play not working after update to Android 4.4.4

Guys, I have a problem with Google Play. I update my X98 Air 3G to Android 4.4.4 and the google play stopped working, then I followed Frontier's fix - I rooted first the tablet with the Frontier's toolbox. I'm using an SD Card from one of my cellphones which has other files on it.

Everything went well until I had to use the Link2SD file to convert the newly installed Google Play into a system app. I'm receiving this error in Link2SD: /system : Not enough storage space. I google this error but I found only an italian forum in which no solution was given.

Also do I have to use a microSD or it works also on the built in memory?

Any advice hot to fix the Google Play?! I'm noob into this rooting stuff, so any help i will highly appreciate.

Million thanks in advance for your time and support.
[Teclast X98 Air 3G] qrious:
luckone.......I ran into the same problem and asked on this forum..what system apps were safe to remove and didn't receive an answer so I went ahead and deleted the teclast app and the Iqfly app ...I think that is what it was called and it made enough space to create the system app....
[Teclast X98 Air 3G] luckone:
I have plenty of space also on the tablet's drive (about 10-15 free GBs) and around 10 free on microSD. So it's not about free space is more related to how to fix the Google Play and stop it from crashing. I also checked Teclast site and it seems they don't have an email address for support, just for sales.
[Teclast X98 Air 3G] qrious:
luckone it is about "system space" not to be confused with the amount of space on the drive......

Hello, I have a teclast X98 Air 3G (C6J6), I arrived 15 days ago. The automatically upgrade to android 4.4.4 and version 2.0 kitkat. It has happened so many. The play store no rula. After much looking, searching and trying solutions everywhere, none has funciondo, and have tried countless of them. Today I managed rootearla and that works perfectly I play store. I will explain the steps you make.

Do you need the driver for the pc recognize the tablet, I have xp and recognized without problems, you simplemete accept the certificate warning leaving you, period.

IMPORTANT: q you put in the talbet in settings-dialing options of development DEPURACION USB LOCATIONS AND SIMULATED also mark. otherwise the pc does not recognize the tablet.

You have to download this program. I have tried many and none work but this itself. This in Chinese and goes perfectly, it is this VRoot_1.7.9.9730_Setup. I put the download link.

ttp: //dfiles.eu/files/eiz87ibaf (lacks h pq I can not put the entire link, it detects as spam).

1º- factory data reset. This is done in settings-security- copy restore factory settings.

Once started the tablet, I still kitkat android 4.4.4 and version 2.0.

2º- No upgrade anything vroot and once installed on the PC, open it, connect the tablet pc and vroot try to recognize your device if you do not acknowledge is q do not have the driver. Find them online. If you recognize you appear in the tablet a notice in Chinese with two options, itches and looks right. BE PATIENT. If all goes well, the tables are reiciciara and already have rootear. To know if this rooteada install root checker, if you ask permission and put everything green is q this rooteada.

3º- To play store, install Link2SD program, open it, look for the application store spades play over and choose actions become reinicas app and system. If he says no space q erases any application which but be careful. To me I did not need. This should be OK.

I AM NOT RESPONSIBLE FOR ANY REASON OUT IF SOMETHING WRONG. I did well and perfect. There are tutorials on how to use vroot and Link2SD.
[Teclast X98 Air 3G] whymoo:
I don't think they changed it, all the tablets use a global model of fibocom 350h otherwise there would have to be a differen't driver. I'm hopeing the us version of the fibocom 350h won't require differen't drivers and just opening the tablet and changing the fibocom chip will work, anybody know for sure?
[Teclast X98 Air 3G] jcespi2005:
The free space needed to convert a user app to system app is on the system partition (about 1,3Gb total on stock).

If you wanna do in the easy way, once you're rooted, install SystemCleanUp (from Play Store), and the app let you know what app can be deleted, but as said in previous posts, almost all chinese apps can be deleted, just take care to have an aditional launcher line Nova or Apex in case you delete the default one...

I used the intel APP for Android.

but you need the tablet to properly boot the android os

the .apk is in the Bios.rar attachment
[Teclast X98 Air 3G] 25gee:
Yes! this is perfectly normal, you continue through the installation and grab the drivers zip on the first page, install the driver under gyroscope and run the registry file.

After that go into device manager find the unknown device, install drivers and point manually to the drivers folder (it will install but fail to enable this is normal) from here simply right click on the display that installed, disable it and re-enable, you may want to do the same with the 2 I/O devices for the orientation and accelerometer to fix the inverted screen rotation ;)

Heat dissipation vs. freeze

At what temperatures do you encounter freezes (i.e. playing real racing 3 on Android)

I'm using CpuTemp from playstore with CPU temperature overlay (so I can see the actual temperature while performing tests) and if tablet freezes it shows around 54'C. Using 3DMark benchmark or Unity benchmark I don't encounter freezes as the temperature tops at 52'C. I get this temperatures indoor with leader protective case.

My tablet is heat dissipation tweaked.

[Teclast X98 Air 3G] ImJamIN:
The bios you upload seems the first version tPAD 1.02 (date and time) but I'm not sure.

For the differences I belive that is not so important. I have seen much bios in these days and everyone had differences. This is because the bios are loaded on our device. If they were taken 'virgin' like those on teclast website (original) we will not see any difference.

But this isn't a problem because when the bios is flashed, at first run it will be modify for every our tablet.
