Hello.I have buy a teclast x98 air 3g 64gb dual OS and the version is c9j6.Is this a new one?Because i saw version j7 ,j8.What is the meaning of the versions?

It's not possible, android is not working on NTFS and Windows can't r/w on ext4 :P

Just run regedit and change the following key. You should see 'sleep' option.

I am seeing that this tablet is only playing 720 p videos when I am trying online videos not more than that. Is there any settings that I need to check. Please update me.
[Teclast X98 Air 3G] ImJamIN:
Hi,

download attachment and unzip it.

I've reduced cache from 1Gb to 512Mb.

I left intact the space of system partition even though the custom roms from Mirek or JCEspi are under 1Gb; this in case you want to return to the stock rom

You will have this situation :

- 22 Gb for Data

- 1.5 Gb for system (default for teclast)

- 512Mb for Cache

Have a good flash ;)

[Teclast X98 Air 3G] muso06:
Hi to all :o

not sure if its a right tread to post but here is my question:

Are 3 models Teclast X98 Air 3G , X98 Air 3G Dual and X98 Air II

have exactly the same processor model and clock speeds ?

if there are different models , witch is the most recent / current model

and has the best overall components and processor real performance speed?

Intel Bay Trail-T Z3736F

Processor Main Frequency: Quad Core, 64-bit, 2.16GHz ?

is the clock speed advertised by Teclast really 2.16 Ghz or

is it in reality less like 1.9 Ghz for example ...anybody ? :confused:

thanks in advance for replies

cheers

muso
[Teclast X98 Air 3G] beefbones:
Yes they are the same, in terms of clock speed, look up Intels website and see what the 2.16hz means, its turbo.
[Teclast X98 Air 3G] muso06:
thanks for reply ,

so as i got it right .. turbo means it switches between minimum Base and maximum Burst frequency

when needed ?

like mentioned on intel site:

Processor Base Frequency	1.33 GHz

Burst Frequency	2.16 GHz

are the X98 Teclast Air 3G / Air II tablets ever reach the max Burst frequencies at all ?
[Teclast X98 Air 3G] skompa:
Hi, thanks. But already done. If CsEnabled set to 1, standby gets available in energy profile and for button, but not working. What I see is, the Wifi driver blocks the connected standby (Cs). Already updated to 3007.9.anything from Dell, but powercfg still notifies, that Wifi is not compatible for Cs. Any other ideas or newer driver available anywhere?

Edit: Found the issue: Pattern match must enabled. Afterwards reconnect including reentering the passphrase and everything works fine.

thank you again and again :D
[Teclast X98 Air 3G] aztecp2:
Jamin Thank you so much.!!!!

I'll be using more android than windows.

then, what's the best number for cache?

I don't mind even if it's 5GB as long as it's super fast

can you please change cache?

you can pick 1GB, 1.5GB, 2GB, 3GB, or whatever!!

the fastest one!! thank you!!
[Teclast X98 Air 3G] ImJamIN:
Cache use in Android it's very poor.

If you have read the old post you can find that most of the partitions from mirek or JCEspi have given 100Mb to cache.

So, 500Mb are enough. Give 2 or 3 Gb are wasted.

But if you want to have 1gb I can give you the new partitions file, but remember that probably you will use 50/70 Mb. .. ;)

Imstall Android Without droidboot

I don't know why, but my droidboot is corrupted. I can get into dnx mode, but can't get into droidboot mode, so I can't install android on it using Intel flashing tools.

I have the dual bios installed and I'm running windows on it.

Is there any way I can install android on it directly from windows or efi shell ? If not, how could I restore / fix the droidboot so I can install android on it ?

Thanks !

Try installing the drivers from the post #6849. They are 3007.10. But I do not think that will make a difference. I have also C9J8 and didn't have the problem you are describing.

[Teclast X98 Air 3G] aztecp2:

I put your partion.tbl in mirek's rom folder, and if I select flash-full_with_pattitioning.xml in Manufacturing Flash Tool, flash-full_with_pattitioning.xml will read whatever from partition.tbl automatically.

is it correct?

I mean that 32GB was the problem everytime so I asked you tons of times.. :(

thank you for your help
[Teclast X98 Air 3G] ImJamIN:
I'm using the same file and I've tried to install windows and the 64gb card is recognised. In fact I can install windows in the remain free space (about 35gb).

So, why android show that, I don't know because i have got the partition file from teclast c9j6,
[Teclast X98 Air 3G] skompa:
Hi pvdas, thanks for your help. What I found out: wake from pattern match must enabled, otherwise Cs gets blocked by Wifi and standby will not work, although gets shown in energy profile. With the newest driver from #6849 it works still fine too. For the SDIO hardware I use the "outdated" Intel driver delivered from stock. So my issue is closed here. ?
[Teclast X98 Air 3G] salespalace:
guys, no one seems to have specified exactly whether rooting the device would lose dual boot or interfere negatively with the bios.

if someone can confirm what happens, it'd be great.

I've gone through nearly this whole thread and haven't found a concrete answer.
[Teclast X98 Air 3G] reeferuk1:
it just roots and reboots, you have nothing to worry about
[Teclast X98 Air 3G] wokadoodle:
Hendrickson's last comment on his YouTube video about rooting the Teclast has part of the answer:

Root will not kill the dual boot, if it disappears, hold vol up on boot and the dual boot menu will appear again.

The act of rooting an Android device should have little or nothing to do with BIOS as Android itself doesn't work on the concept of BIOS, whereas Windows PCs generally does.
[Teclast X98 Air 3G] salespalace:
thanks, will be rooting as soon as i get home.

i don't know about you guys, but the idle battery drain on windows is awful. whereas on android it's marvellous. for example, on Android within 8 hours of idle. 1% is lost.

whereas on windows roughly 10-15% is lost.

ofcourse that is removed if i hibernate the tablet. but i don't want to always have that.

i have followed all the guides and advice on how to improve it. but everything other than hibernation does not help.

would be great if someone can help more on this.

cheers.

First time setup

Apologies if this has been asked before or should be obvious.

I have just received my Teclast x98... and was wondering what people would recommend to do to it as an initial setup.

I've set my windows language to English as outlined by Hendrickson's excellent tutorial. Is there any simple way to clean up the default installations (android & Windows) without doing a full reflash? I don't want to go down that route till I've had more time to study the details.

Any suggestions?

Cheers.

another issue i've found was that swiftkey messes up when chaging rerolution and stays messed up after restoring to 2048x1536, only solution seems to be a reboot so far.

Hey guys,

Is the tablet still good?

What I am looking for is a high-res ~9-11 inch display (probably would prefer 4:3 ratio) with dual boot (will most often use win8, but I might need android (could sacrifice android here)), hdmi (not that essential) and decent specs for stability. I was looking at Cube, but ex. they don't offer HDMI on i6, or win8 on Talk x9. Teclast x90hd also looks like a nice deal, but it doesn't offer dual boot. Looks like Teclast x98 ticks the points I want, I am just not sure about the performance - it's pretty old.

Is there a better value deal I could get for around $200, or should I just get this one?

Looking for my first tablet btw

Stuck flashing BIOS on Android

Hi all, yesterday I was flashing dual boot bios in my tablet (C8J7) from Android, from mirek190 ROM. This ROM doesn't include UpdateIFWI.apk so I donwloaded it from the apk pack in the first post. I tried to flash the BIOS file but it took all the night long and still says "Updating,this may take a few minutes..." so here I am, waiting a few minutes, but asking you for advice too.
[Teclast X98 Air 3G] benbraun322:
Can someone please create a partition table for me to use with Mirek190's ROM?

And everything else will be towards Windows 8.1.

Thanks in Advance :o

Need help and suggestions.

Hi all esteemed xda members. I am in need of some help and guidance. I am explaining my requirements in as much detail as possible.

I received my dual boot Teclast X98 Air 3g today. The back of the tablet says C8J6 as the ID of the tablet. The tablet has 64 GB of eMMC storage. I went through a lot of posts and threads but did not find any relevant information related to 64 GB C8J6 model.

What my tablet has now:

1. No additional accessories like USB charging hub (I have ordered one and it is still in shipment, will take another month to arrive I guess).

2. OTG cable shipped with the tablet.

3. Power charger.

4. Dual Boots works fine.

5. Booted into android and everything appears to be working with a lot of Chinese apps and bloatware. Android has 16GB allocated.

6. Windows 8.1 with Bing is preinstalled which activated fine. Everything works fine here as well.

What I want to do:

1. Install a debloated and rooted Android ROM with approximately 8GB of storage.

2. Install Windows 8.1 Pro on the remaining storage space. (I have valid Win8 Pro license)

Questions I have:

1. Do I need to flash any BIOS or is the current BIOS on C8J6 model good enough for my requested setup?

2. Which ROM to use for Android which provides the best performance with 8GB allocated?

3. Do I need create a separate image using my Win 8.1 pro iso or are there any prebuild win 8.1 pro images available which I can use to install (with my license key)?

If anyone of you would be kind enough to point me to correct posts or provide me with detailed information, I would be very thankful. Any other suggestions or modifications to better my required setup above would be welcome as well. :)

Thanks in advance.
[Teclast X98 Air 3G] ImJamIN:
Hi,

1. Tell us which version is installed on your Tablet

2. There are no big difference between jcespi and mirek, so you have to look at changelog and choose what you think that is suitable for you

3. In first page you can find supercows windows 8.1 pro image. But first I suggest to backup your windows driver with double driver backup ;)

Flash android without affecting Windows / dual boot

Hi there

I've a X98 Air 3G (C8J6), 64 GB Version, with pre-installed dual boot (Windows and Android). I could manage to set Windows 8.1 completely to German. So happy with that.

On Android I set the language to German as well, rooted the device and deinstalled all the chinese apps. Unfortunateley the android system seems to have still chinese parts, e.g. some pop-ups coming up are in chinese.

Now I have two questions

a) is it possible to replace the existing android ROM without affecting the dual boot system? Any guide to follow?

b) is it possible to set the existing android system completely to German / English, so I don't see ANY chinese letters anymore?

Yes it is possible, Using Intel Flashing tool... you need to pick System only which will not touch the Windows Partition.

But Please follow the instructions provided by the ROM developer.

For bios version you must go in bios with DEL key and look at TPad version (1.05 or 1.07 or 1.09)

Dual boot Bios installed....now no access to fast Dnx mode

Hi,

I've flashed my new air I with the dual flash bios. I have not installed windows yet as I was going to try a custom rom for my hc6n but now I cannot get fast dnx mode to engage.

When I press the volume up/down with the power it now just boots directly into android. (I did have dnx mode easily enough before adding the dual bios so I know it's not my technique) I'm nervous about messing with the firmware till I understand it a bit more. Has anyone else seen this? I'm not stuck with the Chinese bloat ware and crashing play store.
