u dont need to get any ipad soecific accessories, for example i bought from aliexpress a bluetooth keyboard, thats looks like ipad's one and it works with me good on windows, and also a bluetooth mouse from the same site and also works perfect, and then u can search for teclast cover, u will find a specific ultrathin for this tablet which i have it now, and its better than any ..... u will find a touch pen with the tablet and otg also.

about linuxn check the comments u will find a link for teclast forum with successful installation of ubuntu, which u can install it normally because we have a bios already, but still u will need usb hub for the installation to use keyboard and mouse, and btw installing windows is not as hard as u think, i just installed windows the normal way by flashing the iso on an usb flash and boot it normally, and then installed all drivers manually, long story short once u will have the bios flashed u can treat the tablet as a normal computer only some drivers complications which needs some updates with the vga and camera specifically.

I've just prowled the Chinese forums again...

It appears that the camera is fixed in Win 10, as reported in this thread...

http://bbs.teclast.com/thread-257760-1-1.html

and

http://bbs.teclast.com/thread-257771-1-1.html

He provides the link for download of Win 10 Build 9879 (apparently he claims that the build in the link is not the normal one gotten from microsoft, he added some components to make the driver work... So not any Win 10 will work):

no pro nor 3g neither hdmi.

If u need to talk to me in italian send me a pm.
[Teclast X98 Air 3G] SUMMERBREEZE:
this means basicly if we install this windows pro at this link and the drivers :

http://xdaforums.com/showpost.php?p=56172528&postcount=3

3G and HDMI will work then, yes?
[Teclast X98 Air 3G] BoORDeL:
Yes ... anyway upgrade video driver with the last with intel driver.

You could use this generic driver finder from intel http://downloadmirror.intel.com/24345/a08/Intel Driver Update Utility Installer.exe
[Teclast X98 Air 3G] SUMMERBREEZE:
thank you :good:

I have caught you here so i wanna ask your oppinion, do you think this 48 hz refresh rate lock issue related to gpu driver or something else?
[Teclast X98 Air 3G] BoORDeL:
Really don't know.

it's said could be driver or bad bios implementation.

anyway i think solvable ... let's wait for teclast engineers to pubblic a stable version of windows (drivers or bios or they both)

sorry for my horrible english.
[Teclast X98 Air 3G] acc007:
Not sure, because I don't have it anymore... But it doesn't use init.d from mirek190 rom because it was not working for me. So perhaps it will work with stock rom as well. Someone please try...
[Teclast X98 Air 3G] SUMMERBREEZE:
how mm thick was the copper plate before and you changed it to a thinner one?

I may be thinking also buying a plate(dunno how mm yet) or copper foil

after your experience, what is the maximum and best thickness for the gap between pcb and screen?
[Teclast X98 Air 3G] jcespi2005:
You're right, so i try to go recovery, and the only valid option is Update ADB SideLoad.

Go to this option, connect the tablet, and use ADB Sideload update.zip and this works fine. Worked fine for me, now i have a FastMode icon, and max and min freq is 396 (instead 640 before the patch).

Attached picture with the recovery screen...

No need to install or use the OTA app ;) anyway you can install and use but take care with the updates ;)

EDIT: Take Tollbox on hand, this update.zip deletes su and you will not be rooted, so need to root again...
[Teclast X98 Air 3G] SUMMERBREEZE:
do you remember the test result with the stock rom at 1080p? or its just a benefit of your rom? or maybe your tablet is more stable than ours at 646 max speed and give better score? [MENTION=4777359]acc007[/MENTION] what do you think?
[Teclast X98 Air 3G] mirek190:
The sock I had only 1 hour.

I have no idea why I have such score.

Futhermore, is it possible to flash the rom from the SP without changing anything on the windows system?
[Teclast X98 Air 3G] mirek190:
Yes it is possible.

Like my ROM has proper XML files for it.
[Teclast X98 Air 3G] Akitoyo:
[MENTION=2198172]mirek190[/MENTION]

Your rom looks really interesting :)

Btw does anyone know where to ask for a subforum for the x98? As already mentioned everything would be more clear.
[Teclast X98 Air 3G] ImJamIN:
I think that new version can have more voltage (by bios) but have down frequency gpu. So there is no problem to play but you buy a tablet that you didn't know that it's downgraded. How much peoples understand this?

[MENTION=228925]Mirek[/MENTION]

There is already a (temp) CWM that's work. Take a look at this thread :

Is that enough?
[Teclast X98 Air 3G] acc007:
I tried with 500, launched Unity Benchmark for Open GL 3.0 and left it playing for one hour. Temp reached 52 deg and it was still working. Then I tried 600 and it got frozen after ca 2 minutes. Will try more tomorrow.
[Teclast X98 Air 3G] SUMMERBREEZE:
maybe somewhere between (550-560 mhz ) , the tablet will have a deal with us :p
[Teclast X98 Air 3G] acc007:
I think every piece has its own limit - some work without problems at 624 (so no fix required for them), and some will probably work max at a bit more over 400mhz...
[Teclast X98 Air 3G] SUMMERBREEZE:
I see ;)

But do you still recommend the HW mod(thermal pads, copper sinks etc ) to eleminate the thermal issue? (making it lower) ?
[Teclast X98 Air 3G] acc007:
These 2 things are independent. My tablet doesn't have more than 52 deg C after HW mod. But of course this is a bit risky if you're not familiar with HW mods. For example you can crack your backcase etc...
[Teclast X98 Air 3G] ImJamIN:
I think that if you can have less °C the tablet says thank you ;)

I cannot apply this update.zip by Teclast Update Tool.

I wasn't able to do it on [MENTION=281521]jcespi2005[/MENTION] ROM so I downloaded I installed one from [MENTION=2198172]mirek190[/MENTION]

I have C9J7 - this can be a problem in this case? What I should do to apply this fix?

BTW, [MENTION=4777359]acc007[/MENTION], your fix (/etc/install-recovery-2.sh) didn't work for me with [MENTION=281521]jcespi2005[/MENTION] ROM. Now I am on [MENTION=2198172]mirek190[/MENTION] so I will try one more time.

Should I apply any special permissions to this file?
[Teclast X98 Air 3G] SUMMERBREEZE:
so many wrong things going on with you mate :) nothing works as i can see..

maybe start from the beginning, flash the factory rom and try like that :good:
[Teclast X98 Air 3G] jcespi2005:
Did you try the ADB Sideload? model should not change nothing...
[Teclast X98 Air 3G] seba2000:
Yeah, it seems that I have some bad luck... Flash factory rom will be the last option (I do not want to do repartition, I have working Windows which I prefer to not touch).

As I good understand (quick uncle Google study) I need to install Android SDK on my computer. I think that I will do it later on.

For now I will check [MENTION=4777359]acc007[/MENTION] fix... (I need to download RR3 files again and I am not sure if I should set any special permission to this file. It will run on startup or I should execute this script?)

Is it possible to UPDATE BIOS without Reinstalling OS?

Hello all,

please, I have AIR II version HG6N with WINDOWS 8.1 only.

Is it possible to update BIOS without reinstalling the OS ?

IS the newest BIOS for 3G compatible with NON 3G version of tablet ?

THANK YOU
[Teclast X98 Air 3G] mirek190:
Right

You can use terminal on android or ADB on your PC.

Where you have adb files just run console

for instance if you have adb files ( 3 files ) on C drive in ADB folder c:/ADB then

In console ( CMD ) just

c:/ADB/adb shell

later su - in deveroper options ( android ) needs debugging on

then cat /sys/class/drm/card0/gt_max_freq_mhz

---------- Post added at 10:52 PM ---------- Previous post was at 10:44 PM ----------

Bios is not related to operating system.

For your device is working dual boot as far as I know.
[Teclast X98 Air 3G] 1KeNnY1KeNnY1:
Thank you

Thank you Mirek,

I am trying to figure out, why my tablet does not charge when system is ON. Please, did you encounter with same issue ?

Wonder if the BIOS update is the same easy, like in Android, via app ?
[Teclast X98 Air 3G] Hendrickson:
I've been working on a 110% noob friendly tutorial video for the last few days on how to:

Flash the dual boot bios from Win 8.1 or Android, or flash an android or windows bios from Windows Or Android

Install Intel MFG tools, load a rom to flash and selecting partition sizes to suit your needs

Enter DnX mode/fast boot. And start the flashing process.

Make a bootable ISO and how to boot to it.

Install Windows 8.1/10

Install the drivers

Remove the android drives that are visible in Windows using the disk management.

And you can use the video to later flash only Android or Windows.

Hopefully it will cut down on a lot of the same questions etc. Hopefully I will have it live tonight, if it doesn't kill me :)

[Teclast X98 Air 3G] seba2000:
Succeed! However not without the fight...

"Official" Teclast update didn't work - I received error in recovery, so I cannot install it.

I tried this on [MENTION=281521]jcespi2005[/MENTION]'s and [MENTION=2198172]mirek190[/MENTION]'s ROMs so I am not sure why it fails...

[MENTION=4777359]acc007[/MENTION] file (/etc/install-recovery-2.sh) didn't work neither - RR3 crashed

What was strange - I checked GPU value by Terminal Emulator in android (thanks [MENTION=2198172]mirek190[/MENTION]) and it was 646 MHz (seems that script executes but didn't change anything)

I used Terminal Emulator (thanks [MENTION=4777359]acc007[/MENTION]):

echo 400 >/sys/class/drm/card0/gt_min_freq_mhz

echo 400 >/sys/class/drm/card0/gt_max_freq_mhz

and tadaam! GPU speed 396, RR3 is working!

charging issue

Thanks mate for reply

the thing is, I did not ever flash bios on this device, or tried any flashing on it. Simply, it stopped charging from Windows, and I think there is probably issue with UEFI Charging Driver.

Tried full WIndows restore, and nothing changed. Once the tablet is off, it will charge, when turned on, it will stop charging.

1) Can you explain how to look GPU MHz?

2) Do you only have to type in Terminal Emulator and does it work?

Hi, you wont be able to install the update.zip on anything other than a completely stock Teclast rom.

It probably wont even work on the stock rom if you have removed any system apps also.

The updater script is looking for a set of parameters to say it is safe to install the update.

Someone maybe able to modify it to by pass the checks.

I haven't found any yet.And I don't know if users with c9j7 or c9j8 have battery drain in windows.Most users don't even know about sleep study reports and maybe they don't even notice they have a drain.Generally the bios thing is a mess since you don't have a version history and no official version.
[Teclast X98 Air 3G] agunghost:
Yap... it needs more power.

You should consider buy hub which is like this one tested by Hendrickson

I have tested another OTG from banggood (4 In 1 Micro USB Power Charging Host OTG Hub Adapter Cable)

However, it can only be used as OTG only or charging only.
[Teclast X98 Air 3G] smartchip:

1. [MENTION=5980665]Akitoyo[/MENTION] already said that, but:

cat /sys/class/drm/card0/gt_max_freq_mhz

2. Yes, execute su before those commands

Unfortunately, now I get error "android system uids inconsistent" when I starting android. I am not sure why it is caused (I made many things yesterday...:))

I am planning to repartition whole disk and install fresh android and windows. Then I can try to make some tests...

BTW, you can do it by your own as well.

Yeah, this can be a problem. However I believe that I noticed that some guys reported about apply this patch (update.zip) on [MENTION=2198172]mirek190[/MENTION] rom...

I am not sure if this is true...

Any micro HDMI - HDMI cable should work. But just do not buy ordinary HDMI-HDMI cable with micro HDMI adapter (according to my experience is much better to use microHDMI - HDMI cable).
[Teclast X98 Air 3G] agunghost:
If speed matters, better go with larger microsd card with higher speed (for example Toshiba Exceria MicroSDXC UHS-I U3 or Sandisk Extreme), not USB 3.0 OTG (because Teclast only has USB 2.0 slot).

It's better in term of writing speed.

I've tested 16 Gb Generic usb 2.0 Toshiba, 16 Gb generic usb 3.0 Sandisk flashdrive and also 32 micro sd UHS 1 Samsung Evo.

The result is no significant difference between usb 2.0 and usb 3.0 flashdrive in term of read and write speed (identical). But the writing speed from micro sd is more than twice speed of usb flash drive.
