[MENTION=1167021]Hendrickson[/MENTION], i purchased the tablet again (C9J8). I had asked them to test the tablet and the seller confirmed that they tested my tablet with benchmark and RR3 many times and it is working, i must believe them this time. So i made the payment (189.9 usd), they will ship it soon(they included the case as gift). My question is, when i get the tablet, it will be dual boot by factory, and both android and windows will be installed..

Can i flash mirek's rom with partitioning (3gb data, 1 gb system, 100kb cache) without touching the windows? or i can flash only system.img and accept the default partitions?
[Teclast X98 Air 3G] Akitoyo:
Where did you buy it?
[Teclast X98 Air 3G] SUMMERBREEZE:
the same place, OKQI. This time i didnt pay until they confirm it works and doesnt have problem with 3D. Also the last fix you found made me buy it, i can just update.zip and play any game with max cpu speed.

I also had got a partial refund before (50 usd + free tablet case) from previous order. I think i will give the old tablet to my brother or sister.

I will let you know if the tablet is OK with gaming once i get it
[Teclast X98 Air 3G] antony84:
I'm waiting my C9J8 tablet.

But reading posts, i'm afraid about battery drain under windows.

Can someone say me if it happens with C9J8 tablets and when this happens (in sleep mode?) ? Thanks.
[Teclast X98 Air 3G] fred7106:
I solve the problem I have modified in init.d the mount script adding the two lines

insmod /system/lib/modules/jbd2.ko

insmod /system/lib/modules/ext4.ko

Seems that the driver are not mounted
[Teclast X98 Air 3G] juaaslo:
Thanks for great work!

Will it be a C8J7 version? If not, is this version compatible with C8J7 tablets? (nobody seems to know real differences between C6J6 and C8J7...)
[Teclast X98 Air 3G] smartchip:
Hmm, not sure if I'm right - the tablet supports NTFS partitions on microSD natively? I just changed the fat32 partition to NTFS on the windows side and was going to install Paragon on Android, but it seems that wasn't needed ... the partition just worked.
[Teclast X98 Air 3G] mirek190:
Do you have camera inverted on my rom ? Have you flashed rom for you device ?
[Teclast X98 Air 3G] SUMMERBREEZE:
i bought the tablet (c9j8) and it will in a week or so..

i want to flash v3.1 rom by you (c9j7)
[MENTION=323861]ImJamIN[/MENTION] said, maybe if i flash your rom to c9j8, camera can be inverted but i didnt try yet :)

I am asking and i want to know how to flash boot.img in case :silly:
[Teclast X98 Air 3G] mirek190:
On video you are using very old version of my rom [emoji12] I presume .
[Teclast X98 Air 3G] agunghost:
I have tested several type of file system while formatting SDCARD. From my test using crystal disk, the highest speed of reading and writing can be achieved if I format sdcard using sd card formatter in this link .

However, for microsd with 64Gb size, it will be formatted to exfat partition.

Now, the problem is, how to access this exfat partition in android?

I can mount it using MLUSB, but it has to be inserted into usb card reader, not in microsd slot. Paragon is also not a solution.

So, Is there anybody has a solution for this?

thanks
[Teclast X98 Air 3G] HDtracer:
Worked out the problem.
[Teclast X98 Air 3G] smartchip:
I want one of these. If only the USB OTG port were in the middle. LOL.
[Teclast X98 Air 3G] vpx:
In my case Mirek190 ROM, Android support NTFS on SDcard without other software or driver.
[Teclast X98 Air 3G] jcespi2005:
You can move manually the OBB folder to external SD, and make a pair on Folder Mount after that. WHen ask about to move files, answer not, and don't delete the internal SD OBB folder, the pair is done folder to folder ;)

I have it working and works really fine ;) good combination with Link2SD for some apps like RR3 or Asphalt 8 ...
[Teclast X98 Air 3G] smartchip:
I'm on stock ROM, so support seems to be baked in. Good to know, now to move the Windows libraries and One Note sync to the microSD.

BTW, I was trying a couple of registry tricks that worked in Windows 8 to get store apps installed on the microSD, but this has been disabled in Windows 8.1. Don't try it, broke the store and had to reinstall Windows to get it working again.

What is it Microsoft and Google have against microSD?!
[Teclast X98 Air 3G] jcespi2005:
Strange, this modules are installed by default, at least on my ROM and stock one... (at kernel level)

/system and /data partition are ext4 by default, so basically these modules (at kernel level) are used by default when the system starts...

I'll try when i got some free time...

---------- Post added at 08:00 AM ---------- Previous post was at 07:56 AM ----------

Seems, for the previous posts, NTFS is supported out of the box on the tablet, so perhaps the best solution is to format NTFS for Android and Windows. extFat is Microsoft proprietary, and probably not supported by default on the microSD and only trough USB reader (haven't tested).
[Teclast X98 Air 3G] TiGer0:
I don't think it is compatible for the HDMI, because Samsung is using MHL & X98 is using micro HDMI.
[Teclast X98 Air 3G] agunghost:
There is no problem for accessing NTFS but the speed (writing) will be only half of exfat.

From my quick test, the best one is using external hdd. However, it miss the practical aspect due to the need of external power.

I haven't tried using ext SSD.
[Teclast X98 Air 3G] Kaiser Souze:
Hi,

I've seen Hendrickson's complete Tutorial video.

I've C6J6 model with stock android (4.4.2) rooted.

I would flash dual boot bios but I haven't the UpdateIFWI application, maybe I've removed it togheter others chinese bloatware app.

How can I reinstall it on my device,please?

Thanks in advance
[Teclast X98 Air 3G] topcatbv:
Do you know what is the HDD maximum storage space or maximum file number that the tablet sees?

Thanks
[Teclast X98 Air 3G] mirek190:
On 4.4.2 that Chinese app to update bios doesn't work. You have to use toolbox to update bios ( remember to swap bios in that tool on your bios ! )

---------- Post added at 12:13 PM ---------- Previous post was at 12:12 PM ----------

You don't have to use ntfs - why just format card to FAT32 ?

I formated my 128 GB card to fat 32.

Questions

Hello i had a few issues i hope i can get some help on. The first, i have the dual boot hgy7n and i made the mistake of wiping my windows. I was able to reinstall it, but ended up losing android. What would be the best way to get androod back? I tried the flash tools with just the system files, but it keeps failing at 30%. Another question i had was about windows. Did anyone else lose sleep function? Under power button options i get only hibernate, shut off, or do nothing. So now i can't use the power button to put it to sleep..very annoying. Any help would be appreciated!
[Teclast X98 Air 3G] Kaiser Souze:
Thanks to your reply and for your work with ROM for X98 Air 3G.

What Toolbox do you mean? The Frontier Toolbox used also for the root?
[Teclast X98 Air 3G] smartchip:
Yeah, originally I partitioned the MicroSD with Fat32 and Ext4. Works well until my OneNote (I use it heavily for notes from my work PC) sync on Windows started eating up all my C drive. Only way to move that (and all the libraries) off to MicroSD was to convert the Fat32 to NTFS.

Also wanted to try installing Windows Store games onto the NTFS partition using a registry edit trick, but that only works on Win8. Haven't found any other way that can be done for Win8.1.

Bottom line, if I weren't starved for space on Windows, I'd stick with Fat32.

---------- Post added at 06:44 PM ---------- Previous post was at 06:28 PM ----------

Yeah, didn't notice that. Would've been a good idea for a desktop dock (of course the X98 ports are in all the wrong places). Charging, USB OTG and HDMI in one, especially for Windows.
[Teclast X98 Air 3G] jcespi2005:
Most easy way is update to 4.4.4 (2.01 or 2.00 is good) and start from this point ;)

---------- Post added at 11:58 AM ---------- Previous post was at 11:57 AM ----------

I tested 1Tb 2.5" HDD and works fine...
[Teclast X98 Air 3G] Kaiser Souze:
Ok, but if I can't update directly from tablet 4.4.2 version because I'vre removed all the chinese app (removed any system apps also?), how can get the toolbox that Mirek190 advice to me?

Is this? http://xdaforums.com/showpost.php?p=58125024&postcount=4768

@ Hendrickson,

Can you please post a review of the Onda V919 Dual Boot 3G Air Tablet when you have had it a while.

I am not sure which tablet to get,

Teclast X98 Dual Boot Air 3G

Onda V919 Dual Boot 3G Air

Both look similar but the Onda has more storage.

Thank you.

wifi issues

hi there,

im having huge wifi issues with my teclast air 2. tried every fix available, but my wifi keeps crashing/slow performance while other devices (in same wifi network) works perfectly.

is this just a bad wifi card in the teclast or is there anything else that can help?

thanks for your assistance!
[Teclast X98 Air 3G] agunghost:
I can format to fat32, but with the price of sacrificing write speed. Since the internal storage is so limited, the option left is to maximizing micro sd usage.

I use it for running portable application, so it needs write speed too, not only read speed.
[Teclast X98 Air 3G] mirek190:
You have to check your rooter.

To swith to work in mixed mode or so.

More control packets etc

You have to remember that tablet works only in 2.4 GHz not 5 GHz wifi - that 2.4 GHz frequency is very noisy environmental .
[Teclast X98 Air 3G] antony84:
So all tablets have battery drain in sleep mode in windows here? Even with dual boot stock bios?

Please, someone not having battery drain in sleep mode could say which bios/config are using? I will use the tablet for windows only... so it's important for me...
[Teclast X98 Air 3G] djeskoswe:
my unit has stock dual boot bios ..
[Teclast X98 Air 3G] grigoris_a:
C6J6 flashed with air II bios no battery drain.Also windows only.
[Teclast X98 Air 3G] antony84:
So seems only bios of x98 air II hasn't battery drain... but GPS is not working. Maybe is GPS that drains battery? Anyway i would not lost the GPS function :(

Someone ask teclast about battery drain problem in windows? Is there a way to ask them about this problem?
[Teclast X98 Air 3G] xusso:
The X98 Air II doesn't come with GPS. Has to be something else.
[Teclast X98 Air 3G] craigg123:
Have done quite a bit of testing, it seems there is no freezing issue with my C6j7 :D. Did about 30 minutes of 3D Mark 11. And allot of Asphalt 8 Airborne. Got temps over 70c in benchmarks but no associated issues.
[Teclast X98 Air 3G] trikst3r:
Do you own AIR II?

Some one posted earlier that his AIR II has GPS.
[Teclast X98 Air 3G] vpx:
I disabled GPS in Windows, still battery drain.
[Teclast X98 Air 3G] Hendrickson:
I haven't tried it with the stock dual boot, as long as you get a matching partition exactly the same and flash only the system you might be able to do it. But I'm unsure as Mirek190's rom has a smaller cache size.

In that video I was, I have the new rom now of course. :)

Thanks I will give it a go! I'm trying to keep my Android partitions as small as possible because I prefer Win8.1, but Android is still better for gaming and apps.

I want to know this myself which is part of the reason I got it. I hope to have it soon, DHL have picked it up but it is just sitting in Hong Kong, not sure what is up with that. At this rate it's going to take 2 weeks to get here! :mad:

Is the wireless speed up and down? Sometimes fast then it just seems to stop then continue? I noticed this on my Air II, but it seemed to have fixed itself when I was installing WIn 8.1 Pro.

On another note, might pay to stay clear of Eternal Team supplier on Aliexpress, I got this message on my X80H Dual Boot order:

Hi dear friend,

Wish you a nice day!

Today we get a news from the shipping company, they said your parcel has been lost during the way, so it is why there is no tracking information updated.

And depends on the rules of our shipping company, we need to do the refund for you,and then send them the refund record .

Here you can open the dispute of “ item has been lost“。

Then we will agree with the dispute,and do the refund for you.

Thanks for your understanding.

May-Eternal team

Very odd, it was UPS. It sounds like me they are doing a bit of insurance shipping fraud maybe? :confused: So far I have found Honesty Team and OKQI to be the best.
[Teclast X98 Air 3G] antony84:
Maybe no one contacted Teclast for this? While a lot of people complaining and contacted them for 3d game issue?

Maybe i'm the only here that would use this tablet for work?!? :confused:
[Teclast X98 Air 3G] Akitoyo:
I'm really interested if the Onda has the dame 3D issue. I think about buying one.
[Teclast X98 Air 3G] Nuja:
that is the battery drain in windows
[Teclast X98 Air 3G] Kaiser Souze:
Perfect.

Sorry another 3 important question, my case is particular case:

1)I must change the bin inside BIOS folder of the Toolbox with the bin file of the dual boot bios, right?

2)Is It not necessary install Intel Manufacturing Tools before use this tool for update from 4.4.2 stock to KitKat? Can I launch directly this toolbox without any installation before?

3)Can I pass to mirek190 or jcespi2005 LIte ROM from 4.4.2 stock with toolbox that you suggest to me and then flash the dual boot bios by UpdateIFWI? Is the UpdateIFWI apk on these cooked roms?

Many thanks for your help!
[Teclast X98 Air 3G] mirek190:
1 - that's right

2 - you have to install Intell manufacturing tool - without it you can't change to any rom for the time being - now I'm working to build proper cwm but need time ....

3 - what the problem - jut update bios by toolbox - this is very easy .

I was never using update FW - I have no idea if will be work properly on cooked rom .

Windows broke my dual boot

Hi all,

So, I read most of this thread and the one about the Air II (which I own). I got the dual boot to work (somehow). I installed the android portion and it was fine. When I installed the Windows using WinPE, it installed.... but the Android logo is not there anymore on the boot screen!

It looks like it replaced the whole thing.

Anybody knows what could have gone wrong?

I was fool to install those updated Intel drivers from techtablets and after numerous tries my touchscreens is still touch half inverted. I've uninstalled and deleted all three drivers and installed them again in correct order. Registry fix is applied and files placed correctly. Still no avail. Tips anyone?

I've tried drivers from drivers package and camera fix package.
[Teclast X98 Air 3G] ewawowa:
I am hoping so. I managed to get annoyed when the google play store didn't work and was messing around and started a bat file. The tablet updated itself and didn't turn on again. I have tried to find the Russian walk through but bing and google translate suck when you have no idea what they should or could say. lol

I bought a new duel boot 3G but it seems a waste of a good tablet if I can get my old air 3g working again.

What Windows benchmarking tool or application is the best for determining whether there are issues in Windows mode?
[Teclast X98 Air 3G] Nuja:
I used "powercfg -sleepstudy" (it generate a html file; when your open it your can see if something is doing the batery draining)

But im using windows with bing that came with the tablet, maybe the problem is in this windows or the driver (and that you dont have the same).

anyone can confirm with the command and report that the tablet with win 8.1 pro doesnt have battery drain from the intel device ?
[Teclast X98 Air 3G] kiru:
I have a C6J7 Windows only tablet (running the preloaded Windows with bing ) and I don't have a battery drain issue, or atleast I dont't think I do. I can push the power button to put the tablet to sleep say at 60% and when I wake it an hour or 2 later it is still at 60%. The only thing I have really done is put the tablet in airplane mode with WiFi and GPS on. I have also installed the wifi drivers posted on the OP (the tablet wouldn't let me install the bt drivers for some reason). The tablet easily lasts 2 days for me on moderate use.
[Teclast X98 Air 3G] craigg123:
Thanks. Issue is sorted and battery is reporting correctly now. Used your tips and the guide on the first page :good:
[Teclast X98 Air 3G] microb77:
So, I was right. The issue is that the windows image, which is Windows 8.1 with Bing (Teclast beta) I found around takes up the whole space.

I have been looking and couldn't find: can anyone point me to the Windows 8.1 with Bing from teclast which will not necessarily take 100% of the disk? Any chances I will get the "office" bonus back?

Thanks!
[Teclast X98 Air 3G] muzetas:
Do you have dual bios or single bios? In my opinion that issue depends of bios version.

[Teclast X98 Air 3G] SUMMERBREEZE:
i dont think it is related to the rom, maybe you were playing a 3D stuff longer time than before and cpu got warmer than before and gave that warning..
[Teclast X98 Air 3G] antony84:
---- wrong
[Teclast X98 Air 3G] Akitoyo:
Well, I really like the x98 and it's awesome features. But I think this is just a work around, it doesn't fix the real problem (no matter if it's a voltage or a temperature issue or what else). Futhermore, it doesn't improve anything on the Windows system. It's great to have this work around if you already bought one of this faulty tablets, but for me it's not a final solution. I will wait until they officially fixed the issue, if this ever happens. Another idea would be to buy this tablet from a more or less German (as I'm from Germany) seller, so if there is the 3D issue I can send it back for free. It costs a few Euros more, but I'll feel safer. Anyway, these are just my two cents. I cross my fingers for you and your new tablet :)
[Teclast X98 Air 3G] SUMMERBREEZE:
thank you, unfortunately in Poland, X98 Air 3G is very expensive and buying from china is the only option, and of course we are playing a lottery at the same time..

For me gaming is the only thing for android OS... I will use Windows for my work, so Android : gaming Windows : the rest.. hope you now understand me well :)

[MENTION=1167021]Hendrickson[/MENTION] and also some blogs reviewed Onda tablets before and as i remember, it doesnt have high scores.. So lets wait a bit more and see what the final solution is for X98 Air 3G..
[Teclast X98 Air 3G] antony84:
So, seems C6J7 is the better bios for windows usage. Respect x98 Air II bios it also let GPS working, right?

Is there a way to dump this bios?

Can all C6J7 (stock bios) owner's confirm no battery drain in sleep mode?

QUESTION:

Do you know if C6J7 tablets are sold yet?

Maybe i could ask the seller to send me C6J7 model instead C9J8 one's. I'm not really interesting in Android... I will use this tablet with windows, and i think it will become powerful with windows 10 (Seems it will allow windows phone apps over desktop windows...)
[Teclast X98 Air 3G] kiru:
If I recall correctly...all C6J7 tablets are windows only. If you order a win only, you will get the C6J7 version.

Not sure if this made a difference or not but I did do a factory restore with the tablet when I got it (using the preloaded windows partition).
[Teclast X98 Air 3G] antony84:
I check just now teclast forum, and someone here in latest days has posted some bios files.

Here the link: http://bbs.teclast.com/thread-263308-1-1.html
