Hi guys. I started a new project, an OTG + Charging USB cable for Teclast tablets, but (from my tests) I didn't found the right configuration to enable the feature and to power the tablet in full charging current (right now I can only power the tablet at 500mah). I found some info about other devices (ex. Nexus, Asus Memopad) that can enable this feature.

http://xdaforums.com/showthread.php?t=2530529

[IMG="charging cable tried"]http://cdn.head-fi.org/7/78/900x900px-LL-781bd011_Y_OTG_CABLE.png[/IMG]​

I know there is an USB hub with this function, so it's really possible enable it, but the circuit previously tried doesn't work in right way..

Does anyone have info about it?

It isn't enough to backup bios to have serial.

You must backup with a program from teclast or with a procedure that it was posted some times ago. So no worry about dumb bios ;)

Small problem with keyboard sound

Hi guys, first of all sorry form my bad english!

I've bought a c8j6 64gb air 3g tablet, i'm quite happy with this. I got a small problem with keyboard sound lag. When I type a word, (in chrome, playstore, everywhere) the first 2-3 letters has no sound output. After that all works without any problem.

Same things for the lock/unlock screen sound. Many times there is no audio output.

I tried many keyboards (android, swiftkey, lollipop) with the same bug. For the lock sound i tried to disable it from settings and use Screen Off & Lock App but nothing changed.

Does anyone have the same issue?

Hi, my 3g on win 8.1 single boot gets often disconnected.

Do you know if there is any way to fix this?

I love this thread but don't you think it'd be better to make a division by topic for better reading? Over 700 pages single thread is crazy.

Cheers.

Windows 8.1 freezes randomly

Hello,

I have trouble specially with windows 8.1 which freezes randomly, sometimes after few minutes of use sometimes after 30 minutes, it is really painful, tried to update the drivers but to no use.

It is more stable on android, but I need windows. Should I go with windows 7? my device is the c6j7 which came with windows at the beginning.

Any help would be appreciated, I'm tired of freezing issue and also sometimes windows will shutdown unexpectedly and very fast, it is really painful.

Thanks

This I can help with.

The Teclast X98 has 32gb of memory - 16gb on Android and 16gb available for Windows.

I have a question too, regarding Frontier's post on page 43 (Yes we go way, way way way way back lol) regarding google play store fix. The guide is really vague and I have no idea how to apply it.

I made a thread about it here http://xdaforums.com/general/help/explain-rooting-guide-android-4-4-t3069723

I really want to use Android, but without google app store, android is pretty useless.. So if anyone could review/help, that'd be great.

I just received yesterday my new tablet, Teclast Air 3G 64Gb Dual-boot (C8J6). The tablet has hardware fault:

In Android I can not play 3D games (for example Asphalt 8). Tablet freezes totally.

This is the second Teclast tablet that I have. First one was exactly same tablet, but model number was C9J6 (I sold it to a friend). There has not been any problems with that tablet and it has been working perfectly.

I know that there is patch for the 3D-game freezing, but why I didn’t have any problems with C9J6?

Will it help, if I install the C9J6 files to the C8J6? I read from somewhere, that the hardware is identical. Is that true?

The seller suggested this:

I did it for android (did not help anything).
[Teclast X98 Air 3G] HowDoesIRoot:
Maybe this patch will help? http://www.teclast.com/en/Information/009.html
[Teclast X98 Air 3G] darkpower2k7:
Thanks for reply

No it loads normally, put in my password and login then it can freeze when I'm Idle or while I'm using it, randomly.

This is driving me crazy.
[Teclast X98 Air 3G] Achiron:
Hi, my tablet recently started getting little unresponsive from time to time on android, with some overheating maybe that causes the touch to stop working and then the device reboots. This happened once and I continued with the game and all was ok. Now I'm flipping through pictures on the windows, and suddenly the screen goes out, and I have to give long press for the device to power up and boot up. Also, I'm in the middle of a dispute with them over the case which is awful. DO you think it's something solvable by diagnosing the problem? Or it's part of the product faultiness?
[Teclast X98 Air 3G] HowDoesIRoot:
To the two above posters, I wish I knew the solution. How long have you had the tablet? Have you tried reformating Windows or Android? I can't think of anything else to do.. I would expect Chinese tablets like these to be faulty.. I use mine once-twice a day to watch TV shows at night, otherwise I don't use it.
[Teclast X98 Air 3G] rudivb:

i tried but no chance to fix the problem :(
[Teclast X98 Air 3G] frank smith:
Thanks!

The 3D-freeze patch helps, but I'm wondering why the C9J6 did not need any patches and C8J6 needs it. What is the difference between them? Software or hardware?

Clock Losing Time

I bought Teclast x 98 AIR (C9J8)about 2 weeks ago from Geekbuying, the 1st problem I noticed was the sim card slot was broken and the HDMI port was not recognizing the HDMI cable both in Android 4.4.4 and Windows 8.1. The Simcard slot was easy to be fixed so they repaired. The HDMI port has not been fixed. I was told by Geekbuying to take to a local repair shop to fix it. Lately I noticed that the tablet is losing time. I searched on the internet for a solution (Setting>System>Date&Time> unchecked automatic date & time and automatic time zone) but it didn't fix it. The clock is still losing time even 1 hour overall. I am looking for a solution but I can't find any solution. I was thinking to flash the tablet (I know nothing about flashing) but from the links on the 1st page I only find roms and updates from C9J7... So I was thinking...

Do you have any solution for the clock losing time?

Do you believe that if install C9J7 roms to C9J8 will I have problems with the drivers?

Is there any video guide how to flash the tablet without deleting the Windows8.1 partition but only the Android partition?

Can I flast only the Android Partition without touching the Windows 8.1 partition?

With Kind Regard

I have seen that c9j6 has newer baytrail processor (serial number) than other 'old' x98. Try to look at your processor serial to be sure that is the same new hardware.

I have had the dual boot air II x98 32GB model for almost a month now. The USB 2.0 Hub you guys have been linking to on aliexpress works great. I currently have 128gb flash drive, a mouse, Griffin Powermate and fiio e10 dac plugged in and everything works flawlessly and the tablet does charge. I am using a 2A charger and I keep it on the hub on the #2 setting. It does charge slowly though. I plan to test with a higher amperage charger soon.
[Teclast X98 Air 3G] benbraun322:
Does anyone know what will happen if I put in a 128Gb Micro SD card?

hi,

similar question here. I would like to make a backup from Windows with a disk-image-programm (macrium reflect free), which is restorable with a rescue-usb-stick.

Which partitions must be saved in the imagefile for this purpose? It is enough to save partitions which are labeled as follows: ESP, system (fat32-formated), microsoft reserved, Windows?

many thanks!

tablet is stock-dualboot (c5j5); non root.

Macrium reflect worked fine with the tablet Asus note 8. But a Android-Windows-dualboot is maybe a little more complicated.

Tablet dead

Hi all,

I have a x98 air 3g, 64gb dual-boot, all stock.

Today I received my micro-hdmi cable.

Upon testing it I wanted to switch from windows to android. I disconnected the hdmi cable, hit reboot in windows and connected the cable seconds before the device finished the shutdown process (wanted to see if the boot sequence is being shown on the external display as well). As I connected it the screen went black and now my tablet is dead.

It seems to be turned off. It doesn't respond to any button I press.

I tried pressing the power button, tried to press it half a minute, nothing.

Also tried combinations of power and volume buttons, nothing.

If I connect a usb keyboard nothing happens. If I activate numbers on the keyboard the light for numbers doesn't show.

The battery was about 80% when the tablet went black. I tried charging it. It didn't change anything. As the charger got hot I assume that loading the battery still works.

Did anyone happen something similar?

Any ideas what I could do to rescue my beloved tab? Or ideas how I could figure out if it is a software issue or if the hardware is broken?

The tab is 4 days old, all stock.

Any help is really appreciated!

Cheers

Hi,

Translation is badly needed.

My x98 air 3g is dead and I need to re-program bios.

Is there any video tutorial shows steps?
[Teclast X98 Air 3G] :
Sounds nice. Any recommendations that aren't too expensive?
[Teclast X98 Air 3G] cosmok82:
Your problem is similar to the one in my project.

There isn't an issue with power supply used (if it's higher than 2A)! I measured the voltage/current from different charger outputs, they depend from the usb configuration on tablet. Actually, this usb cable or hub configuration cannot supply more current than about 1A and it works in a particular situation, that I tested.

This means you can slowly discharging the tablet, but not recharge it (in OTG + charging mode) from the condition in which it finds itself. With your post you confirmed my doubts about aliexpress hub features.

If you have any question or interest in, take a look to my coming article on my blog.

That's bad....

I don't know if it can help, but you can try to reflash bios with a programmer or you have to send to the seller for change it.
[Teclast X98 Air 3G] vengador:
Oh man,

could my bios be affected? I didn't flash anything. Just powered the device off and bam it never turned back on again.

On a previous page i read it could help to push the power button for 10s then release it and push it again for 3s. But that didn't help.
[Teclast X98 Air 3G] ImJamIN:
You have already tried to push power button and it fails. if you have connected hdmi during boot sequence I think that's probably it has something to do with bios so reprogramming it can help but that's strange.

If you don't want to try it you should think to send it back because I have had a similar issue and the tablet is still 'broken'...

Calendar not syncing

Hi all,

I am in a bit of a pickle and hope you guys can help.

I have a Teclast x98 32Gb Dualboot C9J8, with 4.4.4 on the android boot.

I rooted the Android and started deleting some of the chinese bloatware using Link2SD.

I foolishly deleted the google calendar sync file (i think!), and now my calendar will not sync to my google account. The attached screenshots show that my google account has syncing issues now, and there is no calendar option within my account.

I have tried a factory reset but it has still not sorted this issue out. I have also tried re-installing / copying various calendar apk and odex files to system/app but I think I may not be using all the correct files.

Does anyone have any thoughts on how I can rectify this please, or possibly upload their calendar / calendar sync related apk and odex files please?

Many thanks in advance

We shall wait for Hendrickson to dump his EDID data for Air II which already has proper 60Hz timing, then we'll compare. Your EDID is version 1.4 - when trying to edid with Phoenix it says it will be converted to v1.3 (no idea what is the difference), so let's wait for Air II EDID file, maybe it will be enough to use this one.

I've also found this nice EDID editor which supports EDID v1.4, it can also extract data from registry

I had the same problem when I tried to convert play store to a system app, I found a solution. I used the Link2SD to uninstall unwanted system apps to make room for the play store, I cleared about 40 MB space before I successfully convert it.
[Teclast X98 Air 3G] acc007:
When comparing your file for Air II and BoORDeL's one for Air 3G, it seems that these units have totally different displays. Both can have the same resolution, but timings are totally different. For example pixel clock is 200.00 (Air II) vs 164.25 (Air 3G). All other timing parameters differ as well, see "Detailed data" tab in AW EDID Editor. Also Air II seems to have 8bit color depth, and Air 3G - 6bit only.

If anyone wishes to risk, he can use Air II BIN file, then open it with MonInfo, Create INF file and then upgrade display driver under windows. However, use it at your own risk.

Personally I think that this EDID tip isn't a way to go, too much differences, but who knows...
[Teclast X98 Air 3G] Hendrickson:
Your right, they seem to reflect different hardware. Same panel maybe, but the converter or what ever you call it for the DisplayPort signal to the panel. Still I will try the inf now on my Air 3G and let you know the results. Thanks for your efforts.

Btw 48hz Vs 60hz, I did not think it would make a difference. But it's noticeable on the two system when using IE11.

Your problem is clear now with the video it happened to me too when trying to fix the camera.

Obviously your steps to fix the camera were not followed as they should. When touching the screen on the left for example the touch is recorded on the right side. Are you sure the registry setting is the correct as described in post 3?

Uninstall goodix touch and graphics and sensor display reboot. Instal graphics and touch. If touch is ok proceed and install sensor too.

I had a windows tablet Onda V975W, I find it boring as a tablet, pretty much a web browser for me. So I sold it and bought Teclast X98 Air 3G. I think of the two, the Teclast has much superior built quality. It has all the issues you mentioned here. Fortunately I found this thread, I followed the guide to root it. I used the solution found on page 43 to fix the play store. while doing so, I ran into problem when converting to system app, it gave me the system not enough space error message. then I figured out a solution, just uninstall some unwanted system apps to make room for the play store. then I installed the Apex launcher and now I have a fully functional android tablet.

Another reason I chose this tablet is that I am hopeful Teclast will release a firmware to make this a dual system tablet with one key switch.

Did you do the tablet restart that is needed when installing Intel flash tools and also if you don't put the custom. ini file into the Intel folder the flash will hang at 5%.

To edit the time to sleep before hibernation- open up the BAT file by right clicking on it and choose Edit.

Find the line in the bat file where it states 30 Minutes (1800 seconds) and change the 30 minutes to the value you desire (this value is just a note for you to remember next time you want to edit the file).

Then change the actual timeout (in seconds) to the value you want. It's listed as 1800 when you first open the BAT file.

*Note that the timeout is listed in seconds (Default of the Bat file is 30 minutes = 1800 seconds).

Hope that helps.:good:
