Touch screen in android issue

Hi everybody,

I have a techlast x98 air 3G dual os 64GB (C9J6) that substituted my iPad of which I couldn’t be more happy about.

I changed without any problem my Android rom following the useful tutorials described in this forum, changing with Manufacturing tool, I’m actually using the 4.4.4 rom from this tread.

Unfortunely I have the 3D gaming freeze problem, that’s quite an issue for me because I used to play RR3 sometimes on my iPad.

I have a big issue with my touchscreen that stopped working in android while it works perfectly in the OS Selection screen and under Windows, that makes me exclude any hardware issues. I see that germancf have experienced the same issue... How can we solve it?

At the beginning I thought it could be an android rom problem, but even reflashing different roms the touch doesn’t respond, that’s why I’m thinking of a bios issue.

Updating the bios could then solve both the 3D issue and the touchscreen, but there comes the hard part, checking my bios version, looking for a bios upgrade and for a tutorial to make it safely on my C9J6 versíon, possibly without losing my Windows installation that works very well!

I thank you all in advance, your help is very appreciated.

Are you aware of specific differences between C8J6 (64GB, Dualboot) and C9J6 (64GB, Dualboot)?

C9J6 is from a newer timeframe?

I haven't had any overheating issues yet (C9J6 ).

Can make phone call on windows 8.1 with x98 air 3g?

I can't find app to do this :crying:

[Teclast X98 Air 3G] majkel_94:
Nope. It's just SoC fault, propably some units needs a little more voltage to operate on full frequency but Teclast has constant voltage writen in BIOS so some peoples have to limit the freqency to stablize ;)

The heatsink is the same - there is no heatsink, only thermopad which is connecting SoC with aluminium back of the tablet :P

So I have a C8J7 coming in a few days running only Android.

I am planning on installing Dual Boot.

If I test Asphalt 8 in Android before I install dual boot and I have no 3D issues does that mean that when I install dual boot, Windows won't have any 3D freezing either?

Or us it completely unrelated?

Thanks

Reinstall only Android on dual boot

Hi, I have broken my android. I have dual boot in my tablet and was using android when I realised something was not working well, si I have tried boot to recovery to wipe cache and dalvik, But something went wrong and it got stuck at wiping cache for about 10 minutes so I pressed power for 10 seconds to power off.

Then android didn't boot, I can choose it in boot menu but it gets stuck at Teclast logo. Windows is working fine.

So I'd like to reflash android but only android, and let Windows untouch. When I installed dual boot on the tablet, the android installation erased all the memory of the tablet, so I don't want that, and I don't know any way to enter to recovery without using the "reboot to recovery" option in android.

TL;DR - There is any way to flash android without flash all the memory?

I played a few races without any problem. I'm not using the tablet for long gaming sessions, though.

I'm still not sure where to put C8J6 and C9J6. Seemed as the 64GB tablets are mostly fine.

Need Help! Got Dual Boot HG7N and WINDOWS Screwed Up...

So I got this Dual boot (From Factory) Android 4.4 and Windows with Bing (I guess). Windows Side was hanging and what not... So thought out RESETING the WIndow's.. While it was reseting It got Stuck at 35% for ever and I started the Process again.. and It went thorugh..

NOW the Problem Part..

1. All my Windows Tiles have "x" on them... PC Settings or Any other Metro Apps does not open. (So that I can reset Again).

2. On the Desktop side It says windows PRo 9200. See picture. (and Does not activate)

What are my options? Does anyone have Restore file? from same model.. Or is it even possible?

NOTE: Android is Working fine.. and I want to keep them both.

At the OUTSET THANKS A LOT.

Anyone knows ?
[Teclast X98 Air 3G] Petepe10:
I have not tried this, but I would assume that if you extract and copy both the apk and odex files it should work also if you plug them in.

If it fails you probably have to flash a complete rom again.
[Teclast X98 Air 3G] chrissss91:
Thank U, I'll maybe try it after doing a complete dump of partitions.
[Teclast X98 Air 3G] Romeo76:
Hi I did it many times, it's very easy!

0) follow the youtube Hendrickson's tutorial in the first page of this tread first, most of the things are described there!

1) Install Intel Manufacturing flash tool into your PC (not the tablet)

2) setup in settings > general properties VID and PID parameters as described in Hendrickson's video tutorial

3) Download your favorite rom from the first page of this tread and decompress it.

4) Download from here the zip named "ONLY FLASH system.img": I can't post links, but you can find it in the first page, into che FAQ #8

5) copy flash.xml from step 4 and copy it into the rom folder from step 3 where the other flash.xml file is.

6) load flash.xml into IMFT (File > Open), IMFT goes in "Ready to flash!"

7) turn off your techlast

8) turn it on pushing power+volume up+volume down together for 10 secs. It goes in DnX mode

9) Connect your techlast to the PC, then IMFT starts flashing, it will take at least 15-20 mins, so DON'T DISCONNECT OR SWITCH OFF THE PC OR THE TECHLAST. IMFTwill stuck at about 82%-90% it's perfectly normal, just keep waiting.

10) at the end the battery icon will appear on your tablet, then you have done!

That's it.

How to power tablet back after my battery run flat?

My battery went flat and my tablet shut down. I connected it to charger over night and it did not charge and will not power up.

Can someone help me with procedure to "kick start" it back to life?

Thank you
[Teclast X98 Air 3G] abanglek:
mine is c9j8 also have same problem, with older microsoft manifacturing tools. Newer version not even passing the dnx mode. But as long as it's entered fastmode, you're good to go. I'm using modified flashme bat file from toolbox to flash, because i'm too lazy to type the whole commands. The modification is removing few early lines that searching & changing mode stuff, also bypassing delete data part. Try to flash system part only, as well as cleaning temp parts. If you changing part table, then you have to install windows back again, that hastle if you want to install the original wim. Me myself not installing the bing version just because of the fact it's too hassle.

But i'm afraid your your copy have hardware fault, maybe stuck/touch volume button, that simulate multiple button press that always entered dnx mode. Get ready to hardware fix if software fix not working. Simply send it back if this not make any sense.

There are instructions for post-install fixed xposed framework. Just follow the instructions & get all benefits of it (my must have module is youtube adblock & gesture navigation (paid), as well as gravitybox).

If you only want to change dpi, no need for xposed, theres a lot of free app in playstore that can change dpi, as long your device rooted.

Me myself using rootexplorer (paid) to make change, either fix xposed install or changing dpi value (edit buildprop), since i'm preferring gui way, rather than using terminal.

I'm using 240 dpi for android; 1) more logical to make use of high res screen -esp in reading 2) i believe store will think this is mdpi device -for the sake of performance

(no longer using android on this device)

x98 windows

I've tried recovery before & no issues of reactivating (before i'm total remove all the parts, also get rid android).

Try 'ehem' way to activate windows if normal way not working.

Tips for anyone else before making any windows changing: backup the whole registry, keep it in other place, or even in onedrive (crazy 100-150mb worth of reg file). Use 'free window registry repair' to restore back the whole reg, as well as repair any redundant or broken registry.

For metro/modern apps that not working, i also had this issue, that can temporary fix with resetting account, or simply run 'wsreset' in admin mode, everytime windows restarting (worsen by SOD issue -but no more). So i tried more permanent solution & it's work. I'm creating schedule task for wsreset. My setup is put it as highest priority, run every pc log (needed if you have multiple account in windows) or simply every pc start if you have single acc.

x98 windows mouse

since i'm now dedicating this tablet to windows, i try to find how to make this tablet more usable. my issues is desktop mode in windows too frustrating, esp when use it on productivity apps. except for chrome (or i'm using slimjet, chrome base alternative, that far better from original chrome, but with carefull settings), mouse or touchpad is needed for more precise pointing/selecting.

so i try to bough small keyboard with touchpad (about same size of this tablet) for $43, but i can say 'luckily' the item is not in stock & i got refunded. so i looked at other option, there is rapoo e6700 for about same price locally (i don't understand why it's so expensive outside). the issue is it not really small nor thin enough.

so i try to find other option & found this. small app that make use of touch screen as a touchpad that is 'touchmousepointer'. i think this is great apps that i will support even not using the extra features. this touchpad only work in desktop mode & i'm using it only when i'm needed (there is the mouse button beside the keyboard button). all the typical touchpad features is there, 2/3 fingers tap/swipe & others, you name it..

my setup for now is using fullscreen mode, turn off accelerating & speeding the cursor.

maybe it's for you too & with this, it's possible to use with cheaper external keyboard without touchpad or mouse. for me i'm no longer need external keyboard since this is my secondary device that i'm using it when away from my desk. all i need is more precise pointing when on desktop mode.

[Teclast X98 Air 3G] abanglek:
erm, i don't know if this thing can be talk here, but in this case considered okay i think. this tablet have licensed, only activation issues. for me, i have win7 pro license (few actually) that i'll use it as soon as win10 launch. as for now i'm using pro because of original wim too sluggish to install, not much benefits i think bing vs pro.

in this case, k..s or pi.o or whatever sometime not working, the latest that almost no issues is microsoft toolkit. be carefull on where you get it, too easy to get of course just hoax fake app.

Reset Android partition

hi guys, I have a question for you. I installed more apps, some of this junk. Now I find the tablet c9j8 very very slow.

I want to reset the partition of my Android tablet. I proceed from the menu settings and restore? there is a particular procedure to be performed? some of you have already done? best regards
[Teclast X98 Air 3G] streetsmart999:
Thanks for trying to help... but that was the first thing I tried. But Finally I figured out a easy way (kind of), instead of completely removing Android etc. Also, this step will help if someone with "PC Settings DOES NOT OPEN on WIN 8.1 for RESET" I searched allover the inter-web to Make my PC Settings to some how open.. So that I can Reset/Refresh the PC. I tried , WSRESet, Edit Reg Key Settings, CMD lines and even swapping shortcut Icons.. Nothing worked. Finally I found in the corner of the web that S h i f t + RESTART boots into REPAIR /RESET Menu. With that I was able to reset my PC. Everything on Windows side (without touching any Partitions / Android) was brand New . .

2 good things happened with this adventure..

1. After Repairing the first screen is typical windows setup screen and once you select English... everything is in English and US.

2. Some somehow the sleep Problem disappeared. Ran Powercfg cmd's and no more see Intel Or Sound waking it up.

Resetting is bit tricky in the beginning as its in Chinese. Used Google Translate Camera /Picture Translate to see what it says and what buttons are what. Hope this helps someone.
[Teclast X98 Air 3G] abanglek:
Haha, it's good to hear when your issues fixed.

Benefits of backing up registry is it's also backing all the serials (as well as settings), so no issues on activating (or with some app, manually backing all the serials). My SOD issues disappeared when i'm restoring my early reg backup on bing. So backing up whenever Windows in good setting condition, you wont know what will happen then, error, slowdown, malicious, whatever..

That is my point, since i'm choosing not really safe way (or i don't care way ?), i see no point to keep the bing, esp when using 'other' method to activate, or recovery part removed, or ssd re-part (or in my case, I just simply take over the whole 26gb ssd to windows -32gb wtf). need 2 flashdrive method, deal with chinese language.. beside my curiosity to win10 beta that i install on latest build launch date, I just come back to 8.1 pro & appreciate it.

Still trying to make Windows version usable

Currently in android there is practically no battery drain in standby, after 3 hours I am still on 100%. However, windows burns through the battery at a rate of 3% per hour implying a driver/software issue rather than hardware.

I have tried updating the graphics drivers & the wifi / bluetooth drivers, but the battery drain is fairly consistent between 900-1200mW per hour in connected standby. The sleep study always has the top offenders in green and not mention anything above 1% active time.

In one of the first posts in this thread it suggests changing the SD drivers from Intel to Microsoft versions. I did so and it appears that this makes the situation worse and I generally use 1300-1400mW with these drivers.

Recently I installed an updated intel chipset driver. My rate of battery drain within sleep studies did not appear to change, however, it is now reporting something in red in the Top Offenders list.

Unregistered Device \_SB.PC10.SEC0

This reports 100% active time and presumably relates to the cause of the battery drain problem. Googling has not been too helpful, and I was wondering if anyone in XDA might have an idea. Perhaps if I can find a driver for this device I might be able to have a tablet than can enter standby without wiping out the battery!

[Teclast X98 Air 3G] c0manche:
Thinking of just installing windows 8.1 pro on the tablet not bothered about the android partitions is it safe to just launch the windows installer and delete all the partitions and create just a single one without briking the tablet.

Also if in the future if I decide go back to dual boot (if lollipop eventually released) would I be then able to use the manufacturing tools to repartition and go back to dual boot?

Thanks in advance

Random shutdown / hibernate Issue in Windows during charging

Hey guys,

I have read through most of the forum but I have not been able to find anything about the problem which i am facing. I have an Air 3G C9J6 and when i am using windows during charging my tablet randomly shuts down and sometimes hibernates. I have no idea why this is happening? Has anyone else experienced this issue as well? I am not even gaming during this time. I am usually watching videos but it also happens during normal browsing.

I initially thought that this is because of heating because when I ran HWmonitor in the background after the hibernation when I log back in it showed the maximum temperatures from before. I took screenshots of HWmonitor two times after this happened. The screenshots are in the attachment named "shutdown_max.png" and "shutdown_max1.png"

The temperatures are pretty high considering the benchmark test by [MENTION=1167021]Hendrickson[/MENTION]: https://www.youtube.com/watch?v=auXzxeXs_84

I also did the same thing but on battery I played some movies etc for a while but the tablet did not hibernate and the temperatures were even higher. The screenshot is named "No charging test.png". I have no idea now what is the problem. Clearly there is a heating issue with the tablet and something else which causes it to hibernate during charging. Could someone give me there expert opinion?

I have not tested much in android but from my experience I get the "Throttling down brightness due to thermal event" notification again and again. The temperatures I have noticed in android go to about 65 but i think its lower probably because of the Throttling.

I told the people from Aliexpress about the issue and they told me that one of the buyers told them that they used copper plates to reduce the heat and an other one told them that he installed windows completely again and it fixed the issue. So it was not really much help.

Can anyone help me with this problem? I am really confused.

"read only" tablet

Hello, i flashed this bios for installing windows on an allview viva i10g , after reading forum i see that is identical to telecast x98 3g, also it has the same hardware as x98 air 3g, except lower freq proc, and it has a home button near + - volume.

After flashing bios for x98 air 3g to install windows, the tablet boots to telecast logo, and forward to the uefi shell, couning the 4 seconds and enter the shell command line, the screen is upside down and in landscape position, so now i was ready for continuing the install steps , boot windows etc, but there was a problem, the USB would not initialize, OTG keyboard do not work to press DEL or ESC to bios, neither in uefi shell, and also not booting usb stick, trying to boot from internal sd not working, i think internal sd is not bootable by default, the computer do not make beep sound and do not see anything when i connect the tablet (tablet in uefi shell), vol + - and power does nothing, continue to boot to uefi, vol up power or vol down power , nothing, it seems those buttons do not initialize. only the power button works.

So, the tablet is functional, booting, but i cannot interact with it to continue installing windows, or to revert to android (cant enter dnx mode),

Any ideeas? to flash this on usb with some tool without detecting ? Or tools to flash while in uefi shell mode?

If the only way to recover it is SPI programmer, do someone have some guides, info, photos about opening the tablet, bios pinout details, any info that may help,

Thank you.

For me this happens only when charging apparently. I have used it on battery with no issue what so ever.

I think it may have something to do with windows thermal management which I read about from the following link but its just a hunch. https://msdn.microsoft.com/en-us/library/windows/hardware/dn757331(v=vs.85).aspx

USB OTG hub

Hi,

I've ordered the Teclast X98 Air 3G 64Gb last week. (bought it for my backpacking adventure)

I'm already ordering some accessory and reading information I need for the best experience with the tablet.

A powered OTG USB HUB that can charge and use USB ports simultaneously is a must have for me.

I've been searching these threads, but still don't really know what the best buy is.

What I found out/questions:

- The one that Hendrickson uses works good?

- Cheaper HUBs can be used, but there is a specific order of connecting everything?

- A member was talking about buying specific parts, you can connect(total $7), don't know if this works?

- Can you kill your battery/charging by using the wrong item(s)?

- Is it advisable to buy a quality charger?
