[Teclast X98 Air 3G] ImJamIN:
I think that the problem is exactly this; gpu doesn't have any governor that scale the frequency from 313 to 646 but it functions only at one specific frequency.

If you look your min max and average frequency they are the same ! In every version.

So I think that the problem under android can be solved with a different frequency (how the update does) and under Windows an upgrade to the intel driver will probably solve the problem too.

So I think that there isn't any hardware problem, but only thermal problem that it's the most important problem like the bios optimization.

IMHO
[Teclast X98 Air 3G] mnitstanley:
You are partially right. But then one simple question, how SOME tablets handle those 3D and some DON'T ?

The governor for GPU could be missing because throttling of GPU may be a new concept in Android.

But not a new concept for Windows. So how 3D issue in Windows ? How intel drivers incapable of scaling ?

GPU runs at full speed all the time i.e. 646 MHz

And voltage inconsistency occurs when CPU turbo boosts and reaches 2.16 GHz along with peak GPU frequency of 646 MHz.

How Android gets the value 646 MHz ? From BIOS ? If so then BIOS fix may work.

After applying the fastmode fix, the max and min is fixed at 396Mhz.

Why didn't Teclast set the recommended min and max values via the fastmode fix ?

Anyone tried manually setting min to 313MHz and max to 646MHz ?

Any app/software to monitor the GPU freq. ?

How to get GPU frequecny history in Android or Windows ?

It would be nice to see if Onda has proper governor and GPU scaling or not. [MENTION=1167021]Hendrickson[/MENTION] can you check your min and max values for GPU freq on Onda or X10HD ?

Losing wifi password

Finally, I found a way to fix the problem of lost password wifi and now i don't have to enter my wifi password again. (thank to blackrambo9 : http://xdaforums.com/showpost.php?p=58302259&postcount=314)

The tablet must be root.

Follow this steps to correct the problem:

1.Turn off WIFI

2. Goto Settings> General> Backup and turn off the ‘Back up my data’

3. delete all files and folder in the following directory. /data/misc/wifi ; Delete all the files and folders.

4. Once done reboot phone re-enter your WIFI information.

5. To test turn OFF the WIFI wait a few seconds then turn back ON it should remember everything. Next test is to reboot the phone, this will validate everything is working correctly.

This fix work fine for me;)

From what I can tell, the Cube i6 dual only has a 32gb option, which is not good, especially for a dual boot.
[Teclast X98 Air 3G] ImJamIN:
As I said I think tat the problems hardware are only thermal and bios.

I think that other producers have a better bios optimization/configuration and probably have new Intel driver too.

Under android I think that they can have added a governor for gpu or they have downclock it for better thermal dissipation.

Teclast HAS its faults. But I have much dubt that there are some hardware problems (defects)

So yes, android obtain hardware information from boot/droidboot so it know that gpu work at 646mhz but android itself doesn't know how it work (no driver/plugin application).

Windows has problem with old Intel driver. If you try to update them the gpu work much well. But we all know that upgrade Intel driver has some 'problems' (camera and touch).

So new bios (probably 1.09? ) could resolve something (because has new gop information ), but we haven't see it yet... :(

pure android

Sory for another post, but I can not read all the pages and I have a few questions. I have a 3g dualboot x98 teclast after kingroot and iroot.

1. Is it possible to install a pure android on C9J7 (dualboot) obviously preserving Windows, or at least get rid of the apps and especially widgets of Chinese? If so please give me simple instructions :)

2. Do unroot save changes or reset to factory settings?

3. What is the largest capacity of the microSD card which will operate in this tablet?

4. How to get rid of the largest number of Chinese characters on both systems?
[Teclast X98 Air 3G] mirek190:
1 - yes just can install my rom with option system only ( C8J7 )

2 - unroot just remove root.

3 - 128 GB
[Teclast X98 Air 3G] microb77:
follow first page instructions. The simplest is to use the Intel Manufacturing Tools, with one of the ROM provided (I used Mirek, the others work as well).

When flashing, use the Xml named "Flash-System-Only" or along those lines; it will flash only Android and leave your Windows intact - that is if your system is already dualboot with both Windows & Android (which I read it is?)

---------- Post added at 08:27 PM ---------- Previous post was at 07:40 PM ----------

Hi guys,

I like the tablet. I like experimenting on it. Now I'd like to test Ubuntu. What I understand is that for this to work, it has to be (too) the first installed system; unless someone knows how to make it boot correctly with the eMMC. According to a chinese user on the Teclast forums, he succeeded to boot Ubuntu, but to do so he had to

1. Delete all partitions

2. Create 1st partition FAT32 of 1Gb

3. Install Ubuntu (which allowed him to create new partitions)

So, the way I understand it, it should be technically possible to create a dual boot Android/Ubuntu, or a multiboot Android/Ubuntu/Windows, or any combination. Yes, maybe we'd have to boot to windows and then pick between windows and Ubuntu, but I can live with this extra step.

If I am right (I doubt this, but who knows!), if there was a way to create a flash.xml that looks at existing partitions and let them untouched, and then create the android/windows partitions with the remaining space, and install Android accordingly, perhaps this would work?

Of course, the perfect situation would add a 3rd icon at BIOS OS selection, but heh :D

Anyone think it would work and would be willing to either test it, tell me how to test it, or prepare the flash.xml? I don't mind testing it, as I believe I could just reflash a one of the full flash.xml and I'd be fine (OK it means re-installing everything but that's part of the fun).

Anyone?
[Teclast X98 Air 3G] mirek190:
To add extra partition is very easy - you have to add it in partition.tbl

Did you ever find a way to raise the warning limit? I looked but couldn't see if there was ever a solution.

I mostly have the screen at around 50% so that explains why it never seems to dim.

I say random because I can get the warning by turning tablet on from dead cold, opening an email or web browser and it will pop up (not likely that it instantly heats to 55deg doing that) or I can play asphalt or RR3 until the whole back of tablet is super warm and see no warning at all.

Most times though, when gaming the warning pops up after 5mins or so, but sometimes it doesn't

Ubuntu, C9J8 Dual Boot and 32/64bit UEFI

Hopefully this saves others some time that are looking to boot Ubuntu from USB on the dual boot C9J8.

If I understand correctly - it appears that booting into Win8.1 uses a different UEFI to booting into Android. Android UEFI is 64bit, Win8.1 UEFI is 32bit. If your USB stick is prepped for 32bit and you boot into Android it wont work afterwards. Boot back into Windows and it will again. And vice-versa, if your stick is 64bit and you boot into Win8.1 the next time you try to boot off your stick it fails.

It has taken me a very long and frustrating time to work out why all the USB sticks I had working suddenly all stopped working when "nothing" had changed.....

You can use cpu temp apk to get a temperature overlay on your screen. Heating up can go quick, especially charging. In theory there could be other cues other than temp as well, but I have no indications on that.

Anyway, in the folder /system/etc there are 2 files,

In thermal_throttle_config.xml you see

<!--Cooling Devices-->

<ContributingDeviceInfo>

<CDeviceName>Display</CDeviceName>

<CDeviceID>1</CDeviceID>

<CDeviceClassPath>com.android.server.thermal.BrightnessControl</CDeviceClassPath>

<CDeviceThrottlePath>none</CDeviceThrottlePath>

<ThrottleValues>

<ThrottleNormal>100</ThrottleNormal>

<ThrottleWarning>40</ThrottleWarning>

<ThrottleAlert>40</ThrottleAlert>

<ThrottleCritical>40</ThrottleCritical>

</ThrottleValues>

So the screen dims from 100 to 40 per cent if temp gets higher than the warning threshold. I changed the first 40 to a higher number, 70, for a brighter screen. And dim it manually if I do not need high brightnees.

The thresholds are specified in file

thermal_sensor_config.xml with

...

<Sensor>

<SensorID>2</SensorID>

<SensorName>skin1</SensorName>

<SensorPath>auto</SensorPath>

<InputTemp>temp</InputTemp>

<LowTemp>trip_point_0_temp</LowTemp>

<HighTemp>trip_point_1_temp</HighTemp>

<Threshold>

<ThresholdTOff>0</ThresholdTOff>

<ThresholdNormal>55000</ThresholdNormal>

<ThresholdWarning>65000</ThresholdWarning>

<ThresholdAlert>70000</ThresholdAlert>

<ThresholdCritical>75000</ThresholdCritical>

</Threshold>

</Sensor>

Throttling start at 55 degrees, next level 65 etc.

Anyway, I increased 55 to 60.

Fiddling with these numbers is of course with some risk of overheating, but I assume this is minimal for the lowest level.
[Teclast X98 Air 3G] HDtracer:
Thanks. Did changing from 55 to 60 stop most of the warnings popping up?

I think 60 would be pretty safe as that xml allows up to 75 deg.

Can't Press OK Button in the Cancel/OK Binary Choice Dialog Box

Guys, I need your help.

In Android, I somehow cannot press the Ok button in the Cancel/Ok binary choice dialog box. I am not sure this phenomenon appears with all such boxes, but right now I am having difficulty with the one that is shown in the installer when I try to install an .apk file. I thus cannot install those apps from places other than Play Store (I can install apps fine from Play Store).

I cannot press either buttons in the dialog box presented by Super SU when su permissions are requested. :(

I am guessing that this is actually a security measure by some app. Also possibly related to this is that I uninstalled a bunch of Chinese apps a while ago. I was sooo annoyed by them that I did that in haste --- which might not have been a good idea, I admit.
