Hi everyone. I received my x98 air 3g c9j8 from the 8th sale two days ago.

Its absolutely awesome and i love it.

I had one issue so far. I charged for the first time and the charger got really hot. Then part of the tablet got hot 2. I was just casually browsing windows when it froze. I have changed charger since and it doesn't get that hot anymore ut still pretty warm. No more freeze so far.

I read here people want a bios dump of the new c9j8. If you guys tell me hiw to do this ill get you your bios. Detailed instructions please.

Cheers

cant order this item.

Sorry, this order is failed due to internet connection problems.You can go back to shopping cart.
[Teclast X98 Air 3G] rocketbo:
Hi,

The same happened to me once. The problem occurs if you use a WinPE not meant for dual boot. It somehow lets Android disappear. Dont know whether its just hidden somewhere or overwritten. I would suggest, if you take a WinPE image, to use one of the dual boot tutorial in the XDA forum. If you did use that than its probably a different problem.

Cheers

hi how can I check gpu frequency and it is possible install update.zip on Mirek190 rom? If yes how can I do that? Or how can I change frequency of gpu?
[Teclast X98 Air 3G] vpx:
Can you try 'powercfg /a' to show what energy modes does support your tab ? On my C9J7 there is not S1,2,3 modes, only Connected Standby. thx

Does anybody tried OpenPowerCfg from sourceforge ? It allows you to tweek detailed power settings for modes.

Can you upgrade the ram? To 4gb maybe?
[Teclast X98 Air 3G] craigg123:
Mine is the same. Is Intel sst audio keeping your device awake? If so download auto-mute, just Google it, works perfect for me.
[Teclast X98 Air 3G] BPM:
i would like to install grub (or any other bootloader) to my windows partition and install any linux.

so i could be able to first choose between android and windows and if i select windows i get the bootloader to choose between windows and linux.

but before i start to try this i need a solution to select a OS in the bootloader with the touchscreen, a bluetooth-keyboard or via vol+/-/power button.

anybody know a solution for this?

Hands free problem

I buy omtp handsfree for my x98 air 3g

The sounds quality is very good but ihave another problem when i listen to the music auto stop and start my music it make me crazy i change my hands free and app player but i have same problem
[Teclast X98 Air 3G] mnitstanley:
But before that please share a picture of your BIOS.

If it is v1.03 dated 11/21/2014, then it is the same as C8J7 and C9J7.

We believe that teclast has developed v1.09 dated 12/29/2014 which has updated GOP drivers.

Is your Android firmware updated to v1.08_20141225 right out of the box?
[Teclast X98 Air 3G] djeskoswe:
My C9j8 has v1.03 bios
[Teclast X98 Air 3G] mnitstanley:
We know that your C9J8 has v1.03

Want to check this for the C9J8 of 8th Jan Sale.

Thanks

I received today my second tablet (the first one I sended back, with faulty GPU) and I tested a 2TB 3,5" HDD and working well.

Also GPU works ok :D
[Teclast X98 Air 3G] Akitoyo:
Did you pay the shipping back?
[Teclast X98 Air 3G] topcatbv:
Yes, from Romania the shipping back was 20$, they promised a free sleeve with the new tablet (they forgot it, of course :o ). Anyway, I am pleased that the new tablet works ok

today i receive the 8jan dualboot C9J8 model and guess what, the tablet is freezing !!! so they dont test them ...

so now the 2 last tablet i order are defect, one c8j7 cant rotate (dead accelerometer) and one C9J8 3D freeze .....

too much lies from chinese ....

we need to keep writing the request all the time, otherwise they forget about such things..
[Teclast X98 Air 3G] vpx:
Hello, yes Intel SST Audio keeps my device awake, so I tried Auto-Mute, 'powercfg /request' reports everything OK now, but I have still battery drain in Windows and no idea, how to solve it.:mad:
[Teclast X98 Air 3G] Hendrickson:
That is not good, I'm also facing lies from China, with Honesty Team and Eternal Team shippers on Aliexpress. They told me DHL picked up my Onda v919 on the 12th, but I don't have any REAL tracking numbers. I called DHL and nothing is in the system coming to my address. So it's not as if it's sitting in HKG with DHL, but they are just giving me a fake DHL number. DHL don't take a week to pick up a parcel.

I've seen sellers do this before, they lie and give you a fake DHL number as if they are shipping in 3 days as stated. Really they have no stock yet and they are not telling me the truth. And when it ships, oh its DHL fault it took so long to leave China and they give you an "updated DHL number". It's just lies and complete BS.

Then ET says "UPS" lost my X80H, it was never even picked up by them! Just the billing info sent and that is it. Now they say it's lost and if I want them to send another it will take a few weeks as "Teclast" has no stock....Again more lies.... What really happened is they over sold and when it came to UPS picking it up they didn't have stock. So they blame UPS.

I think I'll give Tinydeal.com a try... At least I have protection with paypal with Tinydeal.

WIMBoot or ZipMagic ?

I was wondering if WIMBoot could be used to increase disk space in windows and came across this program "ZIPmagic DoubleSpace" at http://www.zipmagic.co/doublespace.html , wich clames to compress your drive with more options them WIMBoot and on the fly without a windows reinstall. See the screen shot attached (list of features). Has anybody tried this (or similar) or have an opinion on using a program like this?
[Teclast X98 Air 3G] supercowz:
i new this will happen

on 8jan i had 3 tablet at 189$ to pay, but is at that time i got c8j7 defective tablet, i decide to pay only one 8jan dualboot tablet ...

hi,

my C6J6 don't start at all, some hour earlier was ok, now, when I try to start it ... NOTHING NOTHING

I try the charger on my phone and works fine

any idea? it's over?

I buy it from OKQI in Oct. 28 2014

thanks!
[Teclast X98 Air 3G] SUMMERBREEZE:
It is really sad to hear but i believe they will ship both tablets to you somehow.. just insist them to do their job quick or ask your money as full refund..

btw i also bought X80H dual boot for my wife.. what do you think about this tablet [MENTION=1167021]Hendrickson[/MENTION] ? It sounds a good tablet to me and i paid 110 USD for dual boot one and plus free case as gift..
[Teclast X98 Air 3G] xusso:
110USD and free case? Where did you get such a great deal, I'm interested!
[Teclast X98 Air 3G] vijay555:
I'm writing up a guide to convert your normal boot to WimBoot. It's fairly involved but not difficult.

I've seen a lot of advertising for DoubleSpace. It seems a bit spammy but I'd love to know if it works. I believe it costs about $30.

[Teclast X98 Air 3G] Kaiser Souze:
This thread is awesome! A lot of smart people and a lot of people helpful.

Ok tomorrow I'll do the big jump to dual boot. :cool:

Only few others questions:

1)I understand that I can update bios by toolbox. I must swap the .bin file in the bios folder of toolbox with dual boot bios .bin, then attach the Tablet to pc via USB and start the toolbox.I need to install some drivers or tools (for ex. Intel Manufacturing Tools) to make sure that the device is made recognized from toolbox?

2)Is the battery drain on Windows really that remarkable?

3)How did you make 2 partition in the MicroSD memory card, one recognizable from Android and the other from Windows?

4)Anyone has flashed C6J7 bios on C6J6 for only Windows use? If yes where I can find C6J7 bios dump?

I am grateful to all those who want to help me. :good:
[Teclast X98 Air 3G] Hendrickson:
Yep, ET might have good prices but their service is bad. How do you find the Chuwi Vi8? I found it to be really quick, smooth and good eMMC speeds. A great little tablet. I would have kept it if it had HDMI.
[Teclast X98 Air 3G] SUMMERBREEZE:
Hi mate!

I bought it here :

http://www.aliexpress.com/item/In-S...-83GHz-Tablet-PC-Quad-Core-8/32219710836.html

right now it is already 115.99 usd but no case included unfortunately..

When i bought it, it was 117.99 usd and there was a promotion for first 20 buyers get free case. and i had 7 usd store coupon, i used and it cost me only 110.99 usd :good:

But still please ask seller for case for gift, insist them and maybe they will deal with you.. they are open for such deals always. or they will reduce the price 3-4 dollars for you.. they are chinese :D
[Teclast X98 Air 3G] Hendrickson:
1) Yes or you can use the dualboot bin flasher and just rename teh bios file you want to use or edit the bat to your bios rom

2) It's not the best, but on all bay trail tablets I've had they have this. Venue 11 5130, Asus T200ta, T100ta

3) I used Tiny Partition Tool, Windows can onyl read the first partition

4) I can't find the C6J7 bios, you can flash the C6J6 with the Air II bios it works, but it will disable the GPS is the only side effect.

Air II bios is here: http://techtablets.com/download/teclast/x98_air_3g/bios_files/X98_Air_II.zip

[Teclast X98 Air 3G] Kaiser Souze:
Sorry I don't understand this. No driver needed for flash dual boot bios by toolbox but I must rename what?

Ok,no GPS on the C6J6 with Air II bios, but 3G and 60 Hz display refresh are ok? Nobody try C9J8 dual boot bios on C6J6?
[Teclast X98 Air 3G] Xayfer:
wifi issues

yeah exactly. full bars and suddenly a huge drop, then connection lost and no network can be found for some seconds, then its rebuilding up.. so this might be a problem due to to the win 8.1 bing version? i tried the fix from your links but the problem persists. i thought about a workaround buying an external wifi dongle, dunno if that helps.

the same problem is on android, too.

thx for ur help
[Teclast X98 Air 3G] SUMMERBREEZE:
guys you know, C9J7 and C9J8 come with Windows 8.1 bing version (activated)

Do you think it worths installing a plain Windows 8.1 pro version to the tablet and after install the drivers?

I mean, Windows 8.1 will be much better, stable or faster? or no big difference? any suggestions?
[Teclast X98 Air 3G] kiru:
On the teclast site they have an extra download tool or something to help with the WiFi. I had these problems as well and then I installed the file from teclast and my WiFi "seems" to be more stable. I only installed it last night so no longer term tests as of yet. I am at work right now and will link the downolad page when I head home.

---------- Post added at 07:05 PM ---------- Previous post was at 06:59 PM ----------

I have a C6J7 version and tried to install win 8.1 pro and had issues with the drivers. Windows installed fine but when I started to manually install the drivers I ran into some problems where some of the drivers didn't work or wasn't recognized. I mainly struggled with WiFi and Bluetooth and could not get them going. So I reverted back to the windows + bing and everything worked fine. Also, after the win pro install I had the inverted camera issue, which is interesting as I though this was a bios issue, but it seems like a fix was incorporated at the os level.
[Teclast X98 Air 3G] SUMMERBREEZE:
did you follow this guide by [MENTION=1167021]Hendrickson[/MENTION] ?

I have C9J7 with WinPro installed and almost everything is fine (sometimes drops WiFi, but the same problem persists in Android, maybe problem on my tethered phone, and draining issue when sleeping) I activated hibernation and I am happy with my X98 now. No inverted camera. Everything is in English, no Chinese characters
[Teclast X98 Air 3G] SUMMERBREEZE:
which drivers did you install? the ones [MENTION=1167021]Hendrickson[/MENTION] dumped from his tablet (C6J7) ?

So did you solve the battery draining issue with hibernation?

[Teclast X98 Air 3G] kiru:
Yes, I used his drivers. For the life if me I could not get it going. But on the flip side. I did notice the tablet running a bit quicker with pro.

Use Cpu Temperature by mooncakes from playstore.

That message is not dangerous at all. Don't worry.

Use the temperature overlay function to get the temperature reading at all times.

You may also note at what temperature you get this message and share it here.[/QUOTE]

OK I've tested it and I've got message at 65°c

Then I change gpu frequency to 500mhz and temperature was under 60°c in same game.

Hello. One quick question: Can we flash Windows-only bios to android x98 air 2/3g via UpdateIWFI app?
[Teclast X98 Air 3G] agunghost:
Is it possible to upgrade eMMC card?

In the past, some smartphone can be upgraded (for example HTC HD7, but it's an SD Card module).
[Teclast X98 Air 3G] microb77:
OK, follow up!

I bought a air ii and flashed the dual bios of first post.

Followed the instructions.

Only hiccup is I had to use my own windows iso. The one we find around here are WIMs and will use all the space (and get rid of android). Afterward, it went smooth.

Now, I want to get rid of mihome launcher which is included in the ROM... How can I do that?
[Teclast X98 Air 3G] SUMMERBREEZE:
This is very easy :good:

go to this link from your tablet (simply click on it)

CLICK HERE

and download the .apk file. It is Nova Launcher..

Once it finishes downloading, install the .apk file. And make the Nova as the default launcher.. thats it.. Also change the DPI tp 264 ppi. You need root for that though.. Then the tablet will be more smooth

what's improved in the latest update v2.01?

I see Teclast has posted a new update V2.01 for C6J6 on Jan 09, has any one install this update? and what's improved in this version? thanks.
[Teclast X98 Air 3G] juaaslo:
Hello,

I have tested mine with workaround freq of 396Mhz and it works fine. In tests for 1080p the unity benchmark shows "low values" around 9-10fps. But I have seen that if u let the screen go after finishing, it gets up to 11 fps. Then I tried 500 Mhz and it got higher values, and when finished and left the screen going, it stopped in 11,6fps. Then I tried 521 and it stopped at 13,8. And final tests were with 542 and I reached 14,15fps for 1080p, stable. But again, I saw first fps shown are lower but then you leave the screen going and values went higher. What are the values you show here? The first fps after test finishes? Or you leave the test after finishing with "residual" image and wait for "final" values?

For me 542 working fine for this test. Testing RR3 now
[Teclast X98 Air 3G] SUMMERBREEZE:
yes when we ask about the score, we mean actualy the first score the benchmark shows.. we dont need the rest of the benchmark actualy.. so for 396 mhz - 9-10 fps is fine.. and start again.. and repeat it..

and of course when the gpu frq value is higher, then fps is higher..

so for 542 mhz if the the test still go on but no freeze, its great for you.. but the real test is RR3 game (if it lets you play at least 30 minutes of course)
[Teclast X98 Air 3G] juaaslo:
I have been playing around 60 min in a row to RR3 and no freezing at 542 Mhz :)

Quite happy about that, but maybe this thershold is particular to each tablet!

Anyway, I expect this claimed new bios for last batches is the definitive solution, instead of this workaround which doesn't work on windows!!!

BTW, which is best windows image nowadays? Since everything changes from 1 day to the next, maybe the one in first post is outdated???
[Teclast X98 Air 3G] SUMMERBREEZE:
Great, i am happy for you.. but your tablet before was freezing while gaming? this fix is not for each tablet, only for the ones which are problematic :)

BTW, for me windows is just for work.. i am thinking to play games only in android, so i am still happy for this patch works for android at least
[Teclast X98 Air 3G] juaaslo:
Yes, I had a serious problem with freezing. In RR3 I wasn't able to finish the test race...arround 25-30 seconds. I wasn't able to finish a single unity test (1080 nor 720), so I had a real freezing problem. Maybe I could go higher than 542, but I think this is performance enough until final solution is found.

For me windows is the same, not for gaming, although u know, u always want a perfectly working tablet :)

Which is the lighter windows image available?

So I've run the tests on my 8th Jan tablet, no crashes on RR3 or Unity, but my Unity scores are a little low.

I have a sneaking suspicion that they've applied the GPU throttling thing to the tablet before sending it out, can someone let me know how to check?
