Hi all!

Since I still have to receive the tablet I've asked Anna fang about the 3D problem, cause I think they sent me a C9J7 since I've ordered a dual boot model before Christmas... Here is what she replied...

What do you think?
[Teclast X98 Air 3G] SUMMERBREEZE:
first of all, it is not Anna Fang, it is our popular sherry :) she is just a new staff and doesnt have information about the stuff very much.. so dont very much relay on what she says :) now i am in contact with Jessie.. She seems very talented and also has a very good english and understands the technical stuffs.. Anna Fang is not bad too.. now Jessie says, the new batchs C9J8 will not have this problem at all, i wanna believe but hard to believe at the same time :D

I've got no problem updating via OTA eventhough mine is rooted.

After using several days, I've checked that processor speed is arond 400 to 1600.

Using ice storm, it has different score when in windows and android. And it tends to get higher score when in windows.

I always get a hard on with their replies.
[Teclast X98 Air 3G] smartchip:
I reserve my doubts about things the Chinese distributors on Aliexpress say. Mostly, they blame the manufacturer and promise fixes that don't materialise just to make a quick buck.
[Teclast X98 Air 3G] SUMMERBREEZE:
Guys if you are also looking for a good earphone for this tablet, please buy this one.. it is very cheap but has a great sound quality for its price.. basses are great especialy.. i got the blue colour and it also matches to your tablets white colour.

This is a partial solution, but it's a step towards the final solution.

It's partial because we force to use GPU that we know that isn't the problem. So when you play asphalt, tablet make use more of gpu, so we can play "without" using only cpu. That's the reason that we can play more and more, but as you have seen, after some time the load of cpu (throttling? ) make freeze
[Teclast X98 Air 3G] hejabajen:
Apk file

Hi, i recently recieved my X98 Air ii (dual boot) and i also got freeze issues similar to others.

Got this reply from Anna Fang/jessie:

"Hi, please do not worry, for this problem. We have contact Teclast and here is the reason: since it has intergrated graphics from INTEL, we believe the quality for intel cpu will not be bad, and teclast has told it is not a hardware problem, it has something to do with compability.

So Teclast will work on this and creat an APK file in a month to balance it and they will finally work well.

Could you please give them more time?

Thanks,

Jessie"

Now, how would a APK file solve the freezing issues i have in Windows 8.1?

I thought APKs were android files? Please enlighten me :)

[Teclast X98 Air 3G] lrobberl:
So if the fix won't be released as promised, do you think it would be fare to ask for a partial refund just to pay the shipping costs to send the tablet back to the seller and ask them to send me the C9J8?

(of course I'll wait to see if the new ID has actually fixed the problem...)
[Teclast X98 Air 3G] kosrica:
Funny answers from our chinese tablet supplier: I've asked for the hardware version of the tablet and they said to me it is Android 4.4 and Windows 8.1.

I guess we'll have to stick with this kind of conversation if we want to buy a cheap tablet from China.
[Teclast X98 Air 3G] mnitstanley:
OTA update eve after rooting. You sound like the luckiest guy around :p The Midas touch :silly:

Ice Storm of 3Dmark or a separate one ? I tried installing the 3Dmark basic version which is 1.5GB and it failed multiple times. How did you manage to install it in Windows ?

Now I am trying to install it from MS App Store.
[Teclast X98 Air 3G] ImJamIN:
If this is true, why C9J8 or C9J7 haven't any problems?

Have they already mod android? Or the problem is android AND thermal throttling (voltage ecc.)?
[Teclast X98 Air 3G] mnitstanley:
Majority of defect-free tablets means the list of defect-free tablets here

Wait till members start reporting here that C9J8 is alright and has no issues so far.

Aliexpress OKQI store is the Teclast authorized seller.

No recommendation regarding Windows or Android. Still, what most of the users here have done is they bought an Android model and converted to other variants.

If you have no time or don't want to get involved in tinkering, then buy Dual Boot, like I did.

Also the much awaited C9J8 model which is supposed to bedefect-free is a dual boot tablet.
[Teclast X98 Air 3G] ApteryxK:
Thank you for that information, man that's amazing.

As I plan to buy it the 8th january, do you think that the aliexepress stocks will be this new batch ? What do you recommend ? 8th or after ? Because the 8th you have -29$ on their aliexepress account.
[Teclast X98 Air 3G] djeskoswe:
My dualboot c9j8 unit was send with dhl today , Anna says no 3D problems :)

[Teclast X98 Air 3G] mnitstanley:
I have a defective C9J7. But out of the good tablets reported here, majority is C9J7.

[MENTION=3014815]SUMMERBREEZE[/MENTION] They will create a BIOS patch and remove the turbo boost feature to make it usable.

But that would be cheating because you paid for Z3736F but ultimately it will work at 1.33 GHz which is even below Z3735D.

I suspect this because I have seen a famous brand do this to resolve their overheating and battery issues.

They overclocked the Snapdragon 400 processor to 1.6Ghz which gave them an edge over the competitors who were selling same same Snapdragon at 1.4GHz.

Later company send an OTA update and fixes the proc. core to work max at 1 GHz. :p

Buyer lost because they ultimately paid for 1.4 and ended up with paltry 1.

Hilarious. :cowboy:

The whole community is looking up to your tablet like it is the 'messiah'.

Gear up because we are gonna make that tablet work like a lab rat :P

How much did they charge for DHL ?

I am not sure that it will be C9J8. Better make sure about it from the seller before purchase.

Don't rely on Chinese lottery :P

Also, why don't you try this tablet from this seller or from OKQI.

[Teclast X98 Air 3G] ApteryxK:
Congrats ! Where did you buy it ? I would likr to buy the same :D
[Teclast X98 Air 3G] ImJamIN:
I hope this will not the solutions and I think this will not be because if now you buy c9j8 and it's problem's free, you have a z3736f at 1.33ghz? The users will be very angry!

x98 air II

hello friends, my english is not good

bios settings inside emmc secury erase enabled, false doing and i can not use tablet

dnx mode is working, normal power is efi shell

back to android or windows for load, what i can doing

help me please, What can this do for tablet

:rolleyes::rolleyes::rolleyes:
[Teclast X98 Air 3G] thebigfatman:
If you're booting to the EFI Shell, it's because you have the wrong boot device.

To restore defaults, boot to BIOS, in the "Boot" menu, under "Boot Option Priorities", set all 3 option to "Disabled"

Save and Exit

And it'll boot normally again, or "Vol- and Power" for DroidBoot

I switched from Android to Windows just fine, but after reloading the Android BIOS, the boot order was still set for Windows UEFI, even after reloading default settings.
[Teclast X98 Air 3G] keepfishes:
Some people have had touchscreen issues, there's a touch screen test app to test if the touch screen is refreshing quickly enough, I forgot the name of the app, you can try that...

Just to clear the Air (pun not intended), I read the Chinese forum and can confirm that the dual boot is not true dual boot, but it requires flashing the BIOS every time the operating system is changed.

This is not anything new really, I remember reading one of the users here on XDA doing it as well, and he was concerned about the number of times that the BIOS could be rewritten, as frequent rewriting could potentially damage it. Even the authors of the Chinese thread acknowledge his efforts.

I've read on some chinese forums that using a shorter cable works better, due to the problem of resistance...
[Teclast X98 Air 3G] SUMMERBREEZE:
Guys, i have followed the steps on this LINK and collected and combined them all (the cables and converters ) here below..

I did a long search and tried to find the best price/quality ones.. I also added a 4 port hub in it which we will need to connect our devices such keyboard, mouse, pendrive etc. (using our tablet as desktop mode with charging at the same time)

1) USB Male to Micro USB Male Charging Data Cable w/ Switch for Samsung Galaxy Tab 3 - Black (100 CM)

http://www.aliexpress.com/item/USB-...itch-for-Samsung-Galaxy-Tab-3/1876709616.html

2)USB Female to Micro USB Female + Micro USB Male Adapter Cable - Black

http://www.aliexpress.com/item/USB-...e-Micro-5-Pin-Female-Host-OTG/2005996373.html

3) USB Female to Micro USB Female Adapter – Black

4) Usb Hub 4 Ports Black

http://www.aliexpress.com/item/4-port-usb-2-0-hub-black-free-shipping/1702234009.html

These cost only 7 USD all together with free shipping and it will work %90 with our tablet(Dell Venue 8 Pro and Teclast X98 Air 3G are identical tablets, source HERE

[Teclast X98 Air 3G] danny92:
Thanks to the OP for all info related to this great tablet.

Trying to play with power parameters to have the same behaviour as Android in Win8.1, i.e max speed when screen is on, power button shutdown screen and deepsleep the tablet.

But Sleep Mode in Win8.1 is taking long time to wake up the tablet, and have to put password again.

Also, I would like to allocate certain regions of the screen to a keystroke, regarding which application is currently running.

To achieve that, as far as I know, only gesture or Autohotkey can do it : http://superuser.com/questions/731060/detecting-touch-screen-presses-in-autohotkey-in-windows-8
[Teclast X98 Air 3G] BoORDeL:
Just to clear... it's a true cold dual boot, but as stated from you and fro me before , it requires a firmware writing on the fly and the original discussion of this method started in the XDA TECLAST X98 AIR (no 3G) discussion http://xdaforums.com/showpost.php?p=55875461&postcount=250 .

Anyway could we stop writing the same stuff?
[Teclast X98 Air 3G] keepfishes:
Sorry my friend, its not that I want to keep reposting the same stuff, I only brought that up because someone was asking if it was a true dual boot without having to flash the BIOS, and the answer is no. Cheers. :)
[Teclast X98 Air 3G] davidonabus:
Do we expect that the 4.4.4 v2 update eventually be OTA, or must this be installed manually?
[Teclast X98 Air 3G] keepfishes:
I've inquired about an item from the seller and he claims that this works. If so, it reduces the need to buy so many wires, just one will do... Attached is the screenshot of the conversation with him...

[Teclast X98 Air 3G] SUMMERBREEZE:
yes you may be right, a few cables, converter etc but it really works they say on that dell forum page..

about the hub you mentioned, he also told me the same but the other sellers who sell the same hub, write that its for only few tablets..

please read item descriptions, it says ''This Cable support galaxy s4,note 3,thinkpad 8 to use OTG and Charge function at the same time, Other Smartphone or Tablet can use OTG Function or Charge Function only!''

i think the best and safest solution will be getting this one below(15 USD + Free shipping) (the one Hendrickson advises to us on his video HERE

http://www.aliexpress.com/item/Univ...inkpad-8-X98-M80ta-WT-8-Miix2/2038609573.html

but now i am also curious about the charger, everybody say that our tablet is known with slow charging.. What kind of charger will charge it faster? any advises?

The most importang thing is fix 48Hz refresh rate to 60Hz. Dual boot is lower priority. All my videos recorded by phone have 60fps but on Windows mode I see it without full porformance..

Hope that Teclast will realase new model with otcher processor :(

droidboot not working

thank you the bigfatman, How do I install droidboot on tablet
[Teclast X98 Air 3G] jacfry:
One more thing which may differ is that I chose "save and exit" instead of "save and restart". Still as I mentioned before I have browsed through different bios setting and might have unintentionally changed something. Next step would be to desolder the Bat+ wire and wait some time to see if it will be able to start after that.

[Teclast X98 Air 3G] SUMMERBREEZE:
C9J7 also have the same problem, unfortunately.. The supplier agents are very sure that C9J8 will not have any problem at all.. we will see :)
[Teclast X98 Air 3G] ApteryxK:
Man, this looks awesome, the price is too high though, and you have chance to get extra fees, omg quadhd screen ! That's great, but i really don't know, should I buy it... Nobody bought it yet and it can have some defects :( i will look further into this, maybe add 50euro of extra budget... 300ppi really worth it ! Plus it's bigger. You are killing me inside
[Teclast X98 Air 3G] BrocasHelm:
I've tried the Force 4x MSAA option to check if I get freezes. It is much better than before, I got to finish races in RR3 that were too long to finish before. But still it froze, and that happened after a race. Which is strange, it always happened inside the race with the whole 3d graphics and such(where temperature was going up). This time it happened at some menu screen, when temperature was actually dropping.

Anyway, this solution is not good anyway. I tried some Antutu with and without the option enabled and I got way worse graphics performance. I noticed it eralier at the score of unity benchmark, but here in antutu you can see actual numbers.

This is without Force 4x MSAA.

And this is with Force 4x MSAA enabled.

We are talking about +100% 3d performance and +200% 2d performance when the option is disabled.

Let's wait and see if Anna Fang gets a solution, which I really doubt will happen anytime soon(if at all). Still, enabling that developer option makes it more viable for me that doesn't want to reboot into bios and enable/disable turbo mode every time I want to play some 3d game.
[Teclast X98 Air 3G] wxuod:
Hi guys, I also have the 3d freezing problem on a C6J6 bought on November 11th on OKQI. I received today the same message from sherry about that Teclast is creating an apk that solves the problem, that they said that it's due a "software incompatible"..., two weeks ago told me about a firmware update that solves the problem (the last appeared on December) and we know that this firmware dont solves that problem.

I'm on middle of an open dispute now and like some of you I dont know what to believe from them, due that this same apk message was told some weeks ago to another user here, the "about a month" seems that works for every new day. :laugh:

[MENTION=1167021]Hendrickson[/MENTION] bought it and he will make a review for us. so wait a few days more. stay calm :D
[Teclast X98 Air 3G] RakeshReddy:
The wait is killing....X10HD Is too good to be true. Hope this one doesn't have any gpu bugs....as its using the same SOC and dual boot system.....
[Teclast X98 Air 3G] lrobberl:
What if in the C9J8 they only update the bios removing the Intel turbo boost as said earlier? Wouldn't this be a cheat by Teclast? [emoji14]
[Teclast X98 Air 3G] djeskoswe:
If that the case they will have lots of refunds or returns :)
[Teclast X98 Air 3G] SUMMERBREEZE:
You are welcome. I recommend, please contact with them immediately and ask simply below,

1) ask if it is really C9J8 that they will send to you.. be sure about this first.

2) ask them to keep your tablet for 1-2 days specialy to test for you. at least with this benchmark app and RR3 game, give them the links to try :

Unity Benchmark

http://www.mediafire.com/download/faoerw8cx35ft88/com.Maniac.UBenchEnhanced.apk

Alternative link for benchmark app :

http://www63.zippyshare.com/v/80289232/file.html

================

Real Racing 3 (.apk file)

http://www.mediafire.com/download/x2rbg5hv7bvlwts/com.ea.games.r3_row.apk

Alternative link for the game apk

http://www63.zippyshare.com/v/3459349/file.html

3) They told me that they have a technical staff who can do such things.. So the best way to be sure if your piece is defective or not or in good batch or not.. so accept to loose 1-2 extra days for tests and once its a good one and they are sure about it, tell them to ship to you... Its much better than getting a defected tablet, yes? :)

4) and the last one, get a kind of agreement that, if you still get a defected tablet, they will accept the full refund or a partial refund (but a big one) etc.

all is up to you, insist and force them to do these al.. :good:

2.00 to 2.01 update for C8j7

Does anyone have just the 2.00 to 2.01 zip for the C8j7 model? Or do I need to download the whole firmware (550+ MB)
[Teclast X98 Air 3G] BrocasHelm:
I downloaded the whole thing, and after flashing it and once I booted the device, I had a notification to update to v2.02 automatically. But I don't see much difference than before, I just did it because the seller I got my device from gave this as a possible solution for the 3d issue(I knew it wouldn't work, I just had to do it to provide a new video to aliexpress in case I have to open a dispute).

[Teclast X98 Air 3G] SUMMERBREEZE:
while you are making the video, first show the firmwire version and then after record the game :good:
[Teclast X98 Air 3G] BrocasHelm:
Of course, first I open the About settings, then I show CPU-Z to show max frequency is at 2.16GHz and then I run RR3 to show the freezing issue. But hopefully I won't have to get to the whole dispute thing in Aliexpress, I'm not sure it can support the buyer as much as ebay/PayPal do.
[Teclast X98 Air 3G] SUMMERBREEZE:
if you bought it by paypal, then you are a bit luckier than us. Cos paypal always (well almost) stay beside the buyers.. and as partial refund, you can get something 50-60 usd and plus free tablet case for next order (of course you are keeping the tablet) which better than nothing...
[Teclast X98 Air 3G] BrocasHelm:
I got it from Aliexpress seller Tina Wu so I'm in the same situation as most people here. Alipay generally isn't famous for supporting buyers, that's why I hope to settle this with the seller without opening a dispute case there(in the past I did something similar with another item I got from Aliexpress). Once I have it resolved I'll let you guys here know what happened. She still hasn't replied to the video that I sent her though, so I'm just on hold for now.

No ;( DHL where meant to deliver it today, but today is a half holiday here and tomorrow public holiday. So I will now get it on the 7th which sucks. It's only an hour away from me. My Onda v919 64GB dual boot machine has not shipped out either, waiting for that one too.

On another note, testing Diablo 3 (user request) the machine completely locked up! I have it on video to as I was recording how it would play the game for someone. So it seems my C6J7 will freeze after all if it is pushed really really hard in a game like Diablo III. Funny thing is it never crashed before and I played all the play store games and Path of Exile for a while.

Btw Diablo III is not really playable, I wouldn't call 15-20 fps playable.

I hope my X10HD doesn't have a bad z3736F... fingers cross and since it's the first batch I wonder what will be wrong with it!

[Teclast X98 Air 3G] Hendrickson:
Yes true, you'll find that is around 20fps (he is not running fraps and the map has few monsters to render) Once your in town or with 3 others and lots on the screen it bogs down to 15 fps or less. Which isn't really that playable to me. See here in my video:

[YOUTUBE]AA08EYU_Z44[/YOUTUBE]

If you don't lag is playable I guess, it's also a whopping 25GB install that eats up the hold drive, I had to run it from an external drive.
