Y buy simple micro OTG hub 4-5$, use diode Inside for charging tablette :)

[IMG="Micro OTG hub"]http://i01.i.aliimg.com/wsphoto/v0/1754613053_1/Black-Dual-Micro-USB-Host-OTG-Hub-Adapter-Cable-For-Dell-Venue-8-Pro-Windows-8.jpg[/IMG]
[Teclast X98 Air 3G] lion_sta:
I have a simple hub, and when using the mouse at certain times I get a big lag. Is that something that happens to all hubs?
[Teclast X98 Air 3G] rudivb:
So I have to solder a diode by myself?

And can you charge and use USB devices simultaneously?

Can you charge your tablet and use USB devices like the mouse at the same time?

Edit:

Could it be that there is a difference in the new and old models?

That the old models can not charge and OTG simultaneously, but the new models can?
[Teclast X98 Air 3G] pvdas:
Can you get to UEFI shell? Do you see the USB drive through OTG at all? If so try putting the Windows install on a bootable USB stick, formatted Fat32, and use GPT not MBR. Then you should see it in BIOS and you should be able to boot from it too :)

Android 5 or 5.1 ?

Is there any hope to get Android 5.x running on this tablet ?
[Teclast X98 Air 3G] mikbe:
No. Intel hasn't finished its Lollipop for Bay Trail yet.
[Teclast X98 Air 3G] sexyyoyi:
Thanks!

I ended up brought the tablet back to Shenzhen to their repair shop. That place repairs many chinese brand tablets.

Without looking into it too much, the technician said my earphones are too good of a quality. Need to use normal ones. He gave me one with "teclast" brand" marked on it, and the sound is great on it.

I think you are right that I need to use a cheapeone.

BUT strange thing is that after the technician looked at it and did something to it, I didn't have the battery leakage problem for Android 4.4.4 which was bugging me (but I accepted it as a Chinese tablet thing). The battery now holds its power over night without dropping battery (1% at most).

Glad I got that guy too look at it. But guess this many not be available to many of you guys.

I dear mates,

I want to buy this tablet but it is being very hard to read this entire thread.

I would like to ask if you can tell me what are the known issues, bugs and cons of the tablet for I could analyse.

PS: is still possible to root the Android OS without losing the dual boot?

PS2: I saw that are many versions of the AIR II. What is the Best or the one with fewest bugs?

Where is the tutorial to flash bios on windows please ?
[Teclast X98 Air 3G] Bor-ka:
Cons:

High battery drain in windows and android. Bad usb protection (USB charging controller could be fried up by the charger). Bad cooling system (throttling events). Bad android optimization (GPU in 2D mainly). Touch controller dies on random (exact cause is not known) - zero support from Teclast. No light sensor.
[Teclast X98 Air 3G] kulatrax:
Are you refering to air II? Or the 1st version?

Do you mean that Android experience is not so good? That's bad for me, because I will use Android 90% of time :(

[Teclast X98 Air 3G] MarcoPau:
Hello guys, just received my X98 Air 3G. Amazing piece of device.

A couple of questions (windows 8.1 related):

1- touch keyboard is hiding stuff behind. Is it possible to set it to make things underneath slide upwards, resizing the desktop? If I need to look at the bottom of a page or something I won't be able to do it unless I close the keyboard, can't scroll untill the very bottom. I hope you understand what I mean.

2- I changed language, installed language pack and everything, but I still have some chinese characters here and there. You got a clue?

Thanks for helping out!

Received Android tablet, want to install Win 8.1

I received this tablet today and have been trying to install either Dual Boot or Windows only, with no results at all.

The version is C8J7 x98 Air 3G.

1. Since there is not UpdateIFWI (I see it listed under Settings - Apps, but not in the launcher) there is no way of installing Dual Boot from Android.

2. I cannot flash another ROM.

I receive constantly the following message. I tried a different USB already.

3. There seems to be no update available when I load "TeclastAutoUpdate". I only see everzthing in Chinese, though.

At this point I am starting to think that an easy workaround is indeed not possible, and that I will not be able to load Windows 8.1. I just want to try to install it, but I am afraid of bricking a 200 Dollar gift the first day with the Rufus USB method.

What would you recommed in this point?

Thanks for this one! Did the job.

You guys have a clue on the touch keyboard issue? On android everything underneath the keyboard would slide up, here on win 8.1 it gets covered by the keyboard and you have to move things around or close the keyboard in order to use those parts.

Bios 1.07

Here it is the bios 1.07 mod, for work with every tablet.

Before you flash it, remember that I'm not responsible for brick and/or malfunction of your tablet.

So, if you want to try this new bios, consider to buy a programmer.

Hi! Firstly, thank you very much for your opinion!

I stayed disapointed with the tablet right now. Can I ask you what version of Teclast do you have? D'ont you think that problems was solved on the Air II version?
[Teclast X98 Air 3G] ImJamIN:
I don't know what's new, but there isn't any upgrade to the driver's version so maybe a best use of scaling (for heat) and probably (I hope) a best dual boot experience

My version is c9j8 3g dual os, but replace bios to windows only, cleanup ssd & fresh install win8.1 pro. Some says lost gps in this bios, but not in my case, everything works fine. Which version isn't important, there's no magic for improvement in every updated version. What i'm trying to say is general about photoshopped ads, no name, chinese brand product.

I'm not saying this tablet is totally bad, for hardware i can give 5 over 10, but software & optimizations i give 1 for android, 6 for windows (it's just because of microsoft general optimization + no much touch from manufacturer).

Screen is okay, esp resolution, but wasted by not optimized hardware. My copy have 2 tone temperature, white in board area & brown/yellow-ies the rest. I'm doing some temporary fast-fix by putting some paper between board & lcd, so there's little improvement. Maybe when i have some times, i will put better heat isolation material there. Big gap between glass, no treatment over lcd make the screen crazily glare, find out hendrikson youtube about outdoor visibility & it's real. Just because maybe hendrikson not putting any comparison make people that want to buy this tablet in denial, say it about angle whatsoever, but it real, unusable. Even now my tablet have some dust creeping between glass, showing how big the gaps & no seal between. Like i'm said, my volume switch is misaligned, not the button, but in the inside. Seriously i don't know how/why it's move, but it's happened. So i put some tape to secure the switch after realign.

This is real half-bake product. When other say teclast is better then other, i can't imagine how bad is 'others'. If you willing to have long way optimizing this tablet, play with the hardware, you're welcome. But if you want undisturbed fun or you want your bloody job done, maybe this tablet isn't for you.

For $200, for me not really small amount of money. If this tablet sell for $100, maybe i'm not so much complaint. Raise a little the budget, below $300 have better 'real product'. For example when i'm mention about mipad, it's about $240, but it's real, >10 hours battery, 40k antutu score, great screen (no gaps, better dpi, usable outdoor). When i'm mention about switch10, it's about $280 locally for latest 64gb version, seriously, no one complain about the screen +gorilla glass, maybe keyboard little small & mushy. Get full hd version if you have lots of money.

I just to be frank here, no offend. So far i have this tablet & use it when i need it (when away esp), but of course with not much satisfying. I come back to my real laptop or desktop when i need my work done fast. Come back to ipad mini, it's big different in speaker sound & screen quality. I want to get real keyboard for this tablet, but realize it's not worth for more investment. But still i'm quite glad get this product as a part of my gadget experience.
[Teclast X98 Air 3G] Killa-Bee:
I got the Teclast x98 Air 3G (ID: C6J6) , Android.

I am trying to flash the tablet to the latest ROM I downloaded directly from Teclast

X98 Air 3G (C6J6)-Android4.4.4-V2.00-BD41.rar

I followed all the instructions following the Chinese instructions attached inside the RAR file, got all the IDs needed for the flash tool, etc.

I booted the tablet into XnD mode as it states both in the manual of the ROM and the official Intel PDF for that tool.

tried flashing , it started flashing , but then it fails.

Any idea why?
[Teclast X98 Air 3G] Hendrickson:
Unfortunately, it didn't work, still 48hz. Can't get past the 48hz mark as it will say its exceeding the bandwidth when using CustomModeApp. Must need a bios fix for that one so it will allow the display to run at it's full 60hz.

Unless someone here knows how to reg edit hack a custom resolution refresh rate?

Thanks, I will look into this, but first I need to get the touch screen working correctly. I have applied the Camera fix and they work the correct way up! And install everything as directed and I have moved the TouchSetting.gt to Windows/inf

But still I have this issue with the touch screen, only the bottom half works correctly and the top half touch is reversed. Anyone had this issue? If so what is the fix?

Can you upload the monitor driver spomewhere for me to have a go?
[Teclast X98 Air 3G] Hendrickson:
It turns out when I have my monitor connected it says its a color monitor. But the extracted driver is generic PnP monitor. I installed it on my Air 3G and no different. :( When people installed the camera fix and drivers you did it with the unit in portrait mode? Did you reboot after any steps and did you move the touchsettings.gt ? I'm at a loss here as why its working for other but not me.
[Teclast X98 Air 3G] SUMMERBREEZE:
guys, think about it, some of us even were thinking that camera and screen refresh rate issues related to hardware problems but now it seems we fixed the camera problem yes? this mean, they are actually not hardware issues, just software(driver)

im quite hopeful abt screen refresh rate lock issue too.. :good:
[Teclast X98 Air 3G] BoORDeL:
Remove the old device drivers (completly) has shown on post 3 and reboot system.

Now you must have a mouse and a keyboard to operate with the tablet:

reinstall video (from device manager navigate to video card than choose custom driver pointing to first directory of the zip file and install) do not reboot and install HID (second directory, right click on the inf -> choose install) copy and replace (if present) .gt file to windows/inf directory. Do not reboot install kxaccel exe from third dir and click on REG.

Reboot

should be all ok; if not verify values on registry:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\ROOT\SENSOR\0000\Device Parameters\kxfusion]

"Orientation"=hex:01,00,00,01,01,00,02

This is very good, because I I got the same error and asked about 3 pages before what is going on, yet it seems that this thread is only interesting for Windows 8.1 installations.

It would make much more sense if that thread had been split up into an android and into a Windows section.

Nevertheless, I know now that I did nothing wrong, the new tablets sent out by the shops seem to be broken and cannot be flashed anymore with what everyon else did before. And until someone finds out how to fix, we are all stuck. 550g of nice shiny paper weight made by Teclast. And it does not seem that someone here cares much about us users with Android tablets.
[Teclast X98 Air 3G] Hendrickson:
I can confirm my reg values are the same and installed the same. But it seems there are different batches in the touch screen or something. My Air II, Original Air 3G and now the new one have different values in the touchsettings config file. Very odd.
[Teclast X98 Air 3G] BoORDeL:
I am sorry my friend i'd like to help you but i have installed windows from the first day i got this tablet.

i have no experience about issues you are experiencing.

I think most of us have do the same thing because specs of this tablet make it a perfect candidate for windows 8 OS,
[Teclast X98 Air 3G] Frontier:
Is your Android properly rooted? Are you using the latest SuperSU?

This message appears when Link2SD cannot write to /system.

After rooting the tablet, please ensure that SuperSU has the option to provide root access by default to applications (i.e not ask or deny).

Reboot and try again to convert Play Store to system app.
[Teclast X98 Air 3G] acc007:
Hi,

maybe this will help - google for the term "EDID". It's not a matter of gfx driver, but gfx controller. EDID stands for "Extended display identification data", a piece of memory somewhere in gfx controller (in our case perhaps it's bios, or some chipset on motherboard that differs between Air II and Air 3G) that gives a list of supported resolutions to operating systems. I played with it some time ago (I used generic vga driver to connect to my LCD panel from broken laptop, after connecting via hdmi it always reported max 1440x900 although my panel was 1680x1050. After playing with EDID and manually changing the driver it windows, I was able to get native resolution. With edid it is also possible to provide custom resolutions).

As you have both Air II @ 60Hz and Air 3G @48Hz, maybe try extracting EDID data for both and compare them ?

I used these tools on Windows:

- Phoenix EDID designer v1.3 by Raylar - this tool can extract EDID data from current device (from windows registry), modify modes data and save it as binary .DAT file. Download eg here: www tucows com/download.html?software_id=329441&t=2 (sorry, not possible yet to provide links)

- MonInfo Monitor Asset Manager - a tool to create .inf file, download here: www entechtaiwan com/util/moninfo.shtm

To use it, open Phoenix first, fetch data, modify (I believe it will be just changing 48Hz to 60Hz) and save as .dat file. Then open it with MonInfo to create .INF file. Once you're done, open device manager, choose your monitor and upgrade driver (by selecting generated .inf file). Check the results after restart.

I did this procedure on my LCD 17" panel and worked well. But, as first, use phoenix tool to dump unmodified EDID data from both Air II and Air 3G. Check if there are any differences, so we will see what's possible to do before upgrading monitor driver with .INF file. If you can, please post both binary dumps somewhere, I'll have a look at them as well :)
[Teclast X98 Air 3G] Killa-Bee:
I agree with you, it so should had been split into windows and Android as a separated forums threads.

here is is posted in Android General, but yet 70% of the posts in this thread are Windows related.
[Teclast X98 Air 3G] Hendrickson:
Trying to do this but it doesn't work, when I click in Phoenix to extract the EDID it just closes the app on my and nothing happens. I think it's crashing?

I have a super messed up touch screen on my Air 3G, I have tried a fresh install and done the camera fix over and over the touch screen is always as per below. YET, when I restore the WIndows 8.1 Big image the touch screen is fine, camera isn't of course.

Video best explains my touch screen issue after the camera fix:

[YOUTUBE]Wb2YChNFrxM[/YOUTUBE]

Pulling my hair out trying to fix this stupid issue, I have fixed the upside down cameras to only have this new issue...About to fully give up and quite messing with the Teclast Air 3G and let Teclast fix it themselves!
[Teclast X98 Air 3G] renard01:
Hi Boordel :)

a) Yes, I've tried this and it did not work out at all ... maybe the solution for the air II but does not seem to work for the X98 air 3G.

So currently no way to get a working 4.4.4 Android on that device --- shame on Teclast!!

b) Yes, the X98 air 3G has been shipped but it will take another 10-14 days from experience - i will be glad to dump the bios (if you tell me how to achieve this).

Somebody was asking about the 4..4.4 update. It seems to be working nice except for the playstore problems - no crashes any more with youtube etc - very stable up to now.

I am a litte bit reluctant to flash windows 8.1 on it due to the lack of license, the 48Hz problem and the bad performance people are reporting.

regards,

Renard01
[Teclast X98 Air 3G] acc007:
Does it crash on Air II as well ? Anyway, you can use MonInfo only to extract EDID file to binary file. If you do it on both units, we will know if there is any difference. If there are, please attach these 2 binaries and I might have a look at them in Phoenix. Maybe it will be enough to use EDID data from Air II and apply it to Air 3G... but first we need to obtain these 2 binary files.
