You're totally right, RR3 is sensible to DPI modifications, so in order to install or restore with Titanium you need to go back to stock DPI value... This happens to me also on my OnePlusOne if i modify the DPI, so no related to Teclast or OS, is just a RR3 thing...

After restoring or installing you can go with modified DPI and play the game without issues.

I also had huge battery drain in windows.With dual bios around 5-7% per hour and with windows only bios around 3%per hour(but also 48hz display).Lately I tried a bios from Hendrickson page that is for air II and my battery drain is around 7% per 16 hours(almost perfect) display is 60hz but the downside is that this bios doesn't list the GPS sensor in hardware manager.
[Teclast X98 Air 3G] BPM:
done ;)
[Teclast X98 Air 3G] Dudeonyx:
That bios you speak of does it work on x98 3g? And if so is it 60hz?

I don't mind GPS not working as I have phone for that
[Teclast X98 Air 3G] djeskoswe:
When i got my unit the GPS was disabled in device manager , so i enabled it !

Will disable it and see if battery is better

[Teclast X98 Air 3G] grigoris_a:
I don't know about x98 3g.I have x98 air 3g C6J6.And yes display is 60hz and NO battery drain in connected standby.
[Teclast X98 Air 3G] Dudeonyx:
Sorry, I meant to say x98 air 3g not x98 3g (forgot that there was such a tablet)

Anyways, could you link me to the post or tell me what page you found it at
[Teclast X98 Air 3G] grigoris_a:
Here http://techtablets.com/teclast-x98-air-3g/downloads/

You will find it under bios files.It has the dual boot and the air ii HG6N.
[Teclast X98 Air 3G] antony84:
Hey people, let me understand!

I will have battery drain with windows, with c9j8 unit also? But in standby only mode or always?

OMG... i thinked 3D game issue was the only poblem of this tablet........
[Teclast X98 Air 3G] grigoris_a:
I can't speak about c9j8 since its factory dual boot.I believe that it will not have these issues.But c6j6 and others that are not factory dual boot have the drain issue in connected standby when converted to dual boot because there is no official bios from teclast to convert them dual boot.
[Teclast X98 Air 3G] Dudeonyx:
Thanks

I have some(a lot) of questions

Just to be clear it works on c6j6 x98 air 3g despite being for x98 air ii?

Also how did you flash the bios, the standard way outlined on the first page?

And lastly after flashing the bios did you have to do anything different from the usual Windows install process? And did 3g still work?

Basically just me tell any issues you had aside from GPS
[Teclast X98 Air 3G] grigoris_a:
Yes it works in c6j6.I was already in windows when I flashed and the process is as described for all the bios versions.3g still works and aside from GPS and the inverted camera issue which I had to apply the fix everything is great.If you are on android you will follow the steps to convert to windows and just use this bios instead of the one in first post.
[Teclast X98 Air 3G] fred7106:
Please which version of MS-Office is useful for Windows 8.1 on the tablet ? On the installation in chinese there is in a folder something called Ms office, but now I have installed english iso and I have not any MS application.

There is under windows some leak of the battery? The tablets runs fast the battery also if it is in sleep (about 7 hours)

After reading the last pages, I'm not making a payment I think. Too much issues with the tablet, and no fixes from Teclast.
[Teclast X98 Air 3G] supercowz:
hi again everyone, sorry i was too busy theses last days

i can confirm now ist not safe to order this tablet, yesterday i receive 3 C8J7 tablet, and one is defective, rotation is not working

is seem a faulty accelerometer, so the tablet wont rotate in android and win8.1, big issue ...

so i was close to order 3 more tablet on 8jan, but did not pay yet, i think they lie too much, and send faulty tablet to clear they stock ....

so be carefull ....
[Teclast X98 Air 3G] antony84:
People please!!!

Who have stock dual boot version (c9j7, c9j8) can confirm no battery drain on windows?

Please answer!

I made payment this night... Am i in time to cancel order before ship?
[Teclast X98 Air 3G] mnitstanley:
Stock dual boot is only C9J7 and C9J8. I have C9J7 and haven't noticed battery drain yet. I haven't seen any C9J7 or C9J8 being reported here for battery drain. Only the 3D issue so far which is still there in some tablets. As per the policy, OKQI shall bear the shipping charge in case of return in case you get a faulty C9J8.

[Teclast X98 Air 3G] Petepe10:
There are some updated files (at least according to the dates, 9 jan etc) at the teclast site, www.teclast.com/tools/pad/putcode.html

But I assume for c8j7 it is still 2.02, so the old version with the OTA integrated probably.
[Teclast X98 Air 3G] SUMMERBREEZE:
simply dont buy this tablet anymore if you are a gamer or doing some heavy 3D stuff! look at other options.. i am really sick of this tablet right now.. maybe this is the reason why it is that cheap..

I don't game much only movies, browsing and a few programs. I bought a Windows only version x98 air 3g which should be arriving early next week, I'm still hoping I get one with a working gpu though! What is the model number of the Windows only versions because the c8J9 is dual boot right?
[Teclast X98 Air 3G] vpx:
I am still little surprised from this tablet. I have it 2-3 weeks and I did not tried any 3D game, because it was not purpose of buying this tablet for me. I need this one primary for work (do some emergency stuff in the field, when smartphone is too small and notebook is too big), for using some native Windows applications(special VPN) and MS Office, reading PDF manuals. On the other hand I need Android, because there are a lot of applications, especially maps and another tools. I am interested in DSLR photography, so I preferred this tablet instead of some ASUS or Lenovo with only 1200x800 screen resolution (at similar price), because photos on retina display looks great. I also bought software for Android for testing and prepare me to certification exams. When I am travelling, I would like to watch some movies (does not matter on OS). So I need Android and Windows tablet in one for both - work and free time, and IMHO in conclusion Teclast X98 is just right for this purpose.
[Teclast X98 Air 3G] supercowz:
i agree with you my friend, advoid order this tablet, to much problem with it, if only you are lucky, you will got that great tablet.... but is like lottery

i order/got 10 tablet, with no 3D issue, bec i guess im good heavy order guy, so they dont send me faulty one .... so when you receive faulty tablet, i guess they know, specially if you are new customer, high chance for you to get fautly one

and now it look like they are clearing stock ...

this morning i got 3 c8j7 and one is faulty, rotate screen is not working, i guess sensor problem ....

how come they dont saw that before ship it ...

about the shiping return, they told me they refund 10$ for shipping back, so if like me send tablet back to china cost 25euro, you will only get 8 euro back ... they dont pay back full shipping return .....

now i have 3 tablet in pending waiting for payment, but i will cancell them, im tired to deal with lies and bull**** from : Shenzhen OKQI Electronics Mall

like teclast they lie too much

that was fun when teclast told us the 3D tablet problem will be fixed with one apk, in one month, too hard to believe...

specially when in one month tablet stock will be sold, and teclast ... will dont care much ....
[Teclast X98 Air 3G] lrobberl:
First of all thanks for the ROM.

I'm still waiting to receive my device (surely a C9J7 model), but I was wondering how to flash the ROM in the android partition only, without touching the Windows partition... Furthermore, if I'd ever want to, how could i get back to the original preinstalled version of Android?

Thanks a lot

I see an update for C9J7 also only with respect to the date not the version . But v1.08 should be dated 20141225 but shows 20141022 which is ridiculous. But no OTA update so far. [MENTION=3014815]SUMMERBREEZE[/MENTION] did you check this?
[Teclast X98 Air 3G] SUMMERBREEZE:
yes i am actualy saying the same! If you are not a gamer, this tablet is great! :)

but never give your tablet to someone if he/she wants to play a game! it can disappoint you and makes you feel ashamed! :silly:

[Teclast X98 Air 3G] smartchip:
Luck of the draw, join the Chinese Tablet Lottery [emoji39]

All seriousness, if you search through the thread with "problems" or "freeze" keywords, you'll get a pretty good picture of current issues. Unfortunately there isn't one specific model that's immune to poor QC - and this applies to ALL Chinese brands.

If it's the first time you're buying a Chinese product, consider possible loss of time and frustration as a balance for the low cost. On the other hand, if you don't get sent a lemon, you've just scored a pretty sweet device.

Hi everybody,

I just call my dealer by live chat (geekbuying.com), here is his response regarding my purchase:

"be at ease that we have tested it before shipping and that all are ok for it , that default item other customers get just a special case "

this is what I said. Thanks a lot

Hello everybody,

I have a Teclast x98 Air 3g (C6J6) with dual boot and I have a know problem but I tried all the methods (I think) but I can't fix it...

In windows the touch in my half screen is inverted. I know, it's answered in the first post but this solution didn't work for me.

If I run that bat in the startup screen it creates a non-working second HID touch interface. Everytime I restart the tablet is the same.

I tried also differents drivers (I really don't know the difference) without any luck. Sometimes I have the touch interface all inverted and other have the half of the screen ok and the half inverted.

I tried to delete the touch settings file in the Windows\inf directory... I also copied that file from a pack of drivers for the tablet...

Nothing work.

Anyone could help me with this? Is there any good package with the drivers or the files needed? any instructions?

By the way, I have the same 3D fault in Android like almost everyone... In windows seems to be Ok, I ran 3DMARK (Windows) without problems.

Thanks a lot and keep going!!!
[Teclast X98 Air 3G] rofejo:
Can someone confirm this?

Yesterday i have installed the latest version (2.01 from full rom and 2.02 via OTA) and I only saw that the Wifi seems to work better (with v2.00 version when powering on sometimes wifi was not working) but, for example, the microphone sound is still bad (but the patch on the first thread works fine)

[Teclast X98 Air 3G] lrobberl:
Man I don't think this would be fair for the seller... I mean sure it has problems with 3D graphics, but, as you also said, this tablet it very good apart from that! So I would think that in the reviews people should maybe rate 3-4 stars if they have the problem and mention it in the review. For those who don't have it I don't understand why they should lie and write a complete negative feedback.

I'm still waiting for my tablet to arrive. If it has problems I'll just ask for a partial refund, which I think it's just fare for both the seller and the costumer, then it'll be up the seller whether complain to teclast or just don't care. It's their business... I mean, if you really don't care about the games, getting a discount on a already cheap tablet wouldn't be convenient to us? :)
[Teclast X98 Air 3G] Maringer:
As a matter of interest, does anybody know how to disable the network (both 2G and 3G) in an attempt to save a bit of power? I'm running the Chinese 'lite' Android ROM. I've actually got a SIM installed but don't plan to take the tablet out of the house and away from WIFI very often, so it would be nice to be able to disable all wireless connections but for WIFI/Bluetooth.

hello,

I own a teclast x98 air 3g.

I installed the dual boot, and android and windows.

It happens to me that when I switch off the tablet from android, I can switch it back on ok.

But when it is switched off from windows, it cannot be switched on just by pressing the botton as usual. I need to do a long-press to reset the tablet, and then it starts fine.

It is more than one case that I know this happens and we have no clue what it can be.

Thank you.

[Teclast X98 Air 3G] smartchip:
I'd tend to agree that the reviews on Aliexpress can be more useful for potential buyers, but buyers should really be doing some research.

As for the "partial refund", these Chinese sellers are banking on the fact that if they make returning the defective goods cost-inefficient for the buyers, fewer people will choose to return them. Negotiate for better return shipping coverage to give yourself the option of returning the tablet for a full refund.

Trust me, they're still turning a profit - most of these tablets are made with components that were stripped from recycled "trade-in" machines or QC rejected stocks by the component manufacturers. Don't believe for a second that the newer model numbers mean they are refining the design or fixing anything. It's nothing more than moving on to a different supply of replacement components.

The product you buy is only worth what you think it's worth. I for one have returned my X98 Air II and am waiting for a replacement - but I did pay a little more to buy it from a local seller in Singapore, so the return process is less of a hassle.

I just cant accept that they describe the the tablet as game monster, they dont mention even 1 line about the problem under the product page. this is not business and if people think this is a business, they can go to hell :laugh: where is honesty here? they know the problem there and do nothing and they send the broken tablets to people STILL.. and when you tell them it is broken, then they say ''please send it back bla bla'' but shipping back cost 3-4 times more than they offer and plus there is no guarantee the next tablet will work fine!

The truth is that everyone who has faulty unit write in this topic but not everyone who has good unit write here.
