Thanks for advice for hdmi and otg hub!

I would ask if someone bought a case with bluetooth keyboard suited for ipad air, and if it works.

I was checking this:

http://www.aliexpress.com/item/Ultra-Thin-Silver-Aluminum-Wireless-Bluetooth-Keyboard-Case-Cover-For-Apple-iPad-5-ipad-air-9/1578636854.html

What do you think? Any other advices?

[Teclast X98 Air 3G] fred7106:
Thanks, but I have not understood this upgrade will be change the Rom or not? Now I have the apps for the fastmode with using the update.zip from teclast and today for the first time I have played Asphlat 8 :smooth and slow respect to the Onda V989.

You are best and thank you for it

And you did great work buddy ! And also thank to you, I have ordered the tablet. Thanks to your video.

THANK YOU FOR IT !

As for GPS, I had it even before on disabled, so doesn't matter really, as I don't use this function even on my phole lol.

The main goal now for me, is to reenable that charging via USB when system is on
[Teclast X98 Air 3G] mirek190:
Aspart 8 is the one of games that needs lower resolution .

Just use screen resolution changer in my rom or do no lad from play and change to 768x1024 150 dpi.

The gem be then will be fully smooth.

Hi,

Has anyone recently bought "Teclast X98 Air 3G Intel Z3736F Quad Core 9.7 Inch Android 4.4 Tablet- SKU168246" from Banggood?

I want to learn its Product Code if somebody know it. Since,I could not get any info from Banggood.

Whether they do not know how to look for the code or they hide it since it is old batch!?

Thanks,

Link2SD troubleshhoot please

Hello,

I recently bought microSDHC card 64GB from Sandisk. I paritioned card to 2 partitions (cca 32GB+30GB).

I am using 1st partition (NTFS) for Windows, saving application to Program Files, Onedrive files, media files.

I planned to use 2nd partition for Link2SD on the android side, but with no luck.

I used Mini Parititon Tool, created second partition on SD card as PRIMARY and EXT4.

1st partition (NTFS) is in Android visible, but Link2SD shows 2nd partition is not mounted. Then I tried to create EXT2 partition instead of EXT4, but still with the same result. Do I need to format EXT2/3/4 partition before using, or it is enough to create EXT partition in Mini Partition Tool ?

Thank you very much for any advice

Windows Gpu fix?

Hi guys.

I got a X98 air ii dual boot tablet, with freezing issues in both android and windows.

I wonder how i can change the gpu freq in Windows so that i at lease can complete a benchmark without freeze?

Hello Guys !!!

For X98

In the Teclast Site we could find new files (C9J7) in date of January the 8th for Windows&Android Rom

Does anyone already tested it ?

I've tested similar keyboards to the one you linked and they are not very good - keys are a little too mushy for me. As a case they work pretty well, but that's another thing you have to put away when you want to use your tablet as a slate. IMHO, have a case that will prop the tablet at a good viewing angle and carry one of the portable standalone keyboard/touchpad combos. This way, you can continue to use the keyboard even when you change to another device.

I found this in a local retail store and it works perfect for both Windows and Android. http://extremepcs.co.za/images/ELETE TPAD BT.gif
[Teclast X98 Air 3G] PWMx:
Observation :

/sys/class/drm/card0/gt_curr_freq = /sys/class/drm/card0/gt_min_freq_mhz

So it always runs at the lowestmost GPU frequency scaling point (whatever that happens to be).

Maybe the GPU frequency scaling driver was broken and because of that the highestmost frequency possible was forced.

The end result is that both CPU and GPU are simultaneously running maximum turbo frequencies - which is obviously too much to some devices.

BTW - Here are few interesting comments about similar Intel GPU stability issues :

Keyboard bluetooth and usb

Hello,

I have tested two types of keyboard. (works on android and w8)

A bluetooth one bought on aliexpress with the tablet - brand new- and works fine. But this kind of keyboard doesn t work for entering bios with otg hub or cable.

One is a Logitech K400 (Wireless) And works great too. This one works for entering bios who support mouse too.

I am using the chinese lite rom and cannot do any updates via CWM/Teclast update or ADB side load, they all fail.

I'm trying to redo the partitions because I want to flash either yours (probably) or mirek's rom. I am using around 150mb cache and almost 1gb system already (and with 32gb of memory why strangle the tablet for the sake of 500mb :) )

I have the spreadsheet, but I was wondering if there was an easy way to tell how much total memory was left to allocate to the data partition (so it is all used) after you had changed the cache and system partitions.

Time for some maths I think. Start with 32gb and calculate each partition amount and start subtracting haha.

Charging times

Hi everybody!

Here's an user with the Windows-only version.

My Teclast X98 Air 3G takes a loooooot of time to do a full charge, 6-8 hours aprox. even turned off. I bought a charger that can give 3A but the problem doesn't change. And it seems that the tablet "eats" more than what can give the charger, so if you're with low battery you can't use it with the charger... Am I the only one with this problem? Any way to solve it? Thanks.
[Teclast X98 Air 3G] jcespi2005:
Take a look to this line extracted from stock ROM:

add -b 5931048 -s $calc($lba_end-16384) -t data -u 80868086-8086-8086-8086-000000000008 -l data -T 0 -P 0 /dev/block/mmcblk0

clock issue under the dual boot

for people who face the issue of one hour difference between android and windows to fix do the following

just hit Start and type regedit.exe in the search box. Hit Enter and navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation. Right click anywhere in the right pane and hit New > DWORD (32-bit) Value. Name it RealTimeIsUniversal, then double click on it and give it a value of 1.

and done, time in windows is exactly the same as android under the correct time zone.
[Teclast X98 Air 3G] HDtracer:
So does it matter what value you use for the data partition then? Just chuck 28GB in there or something?
[Teclast X98 Air 3G] PWMx:
I haven't seen any proper solution yet. Only temporary hack to underclock the GPU.

Intel should deliver working "turbo"-solution. I.e. system level DVFS with thermal feed-back.

This is fundamental limitation of micro-USB charging. It is limited to 5V*2A=10W.

The tablet (and higher end smartphones, as well) can consume more when actively used.

This is especially true for demanding gaming with high display brightness.

So you could be discharging battery even when charger connected.

(And higher currents and/or voltages are not safe with this connector ...)

Only possible solutions are the use of some proprietary connector and charger

or implementing the new USB type-C connector and related high power charging spec.

(The new Nokia tablet is the first with this connector.)

[Teclast X98 Air 3G] mnitstanley:
I didn't believe till now that this problem could be solved at all with a patch since it looked like a defective piece of hardware.

But this explanation looks like the real case and quite logical.

The combination of CPU and GPU engaging in turbo boost at the same time must have led to voltage inconsistency eventually leading to overheating/freezing/crash.

That logic also explains why some of you could run those games with Turbo boost mode OFF.

And also the present solution (Fast Mode) is done by locking the GPU clock thereby avoiding simultaneous burst modes.

Since Dual Boot BIOS didn't have the option to turn off the turbo mode, they have resorted to an OS patch for the time being.

If all this is true then I believe that the 3D issue can be completely avoided or minimized with a BIOS patch.

We know that a new BIOS exists and I also believe that the C9J8 sold on 8th Jan Sale has got this new BIOS.

Awaiting confirmation from new buyers. The new BIOS is the only solution as I see it.

I will be disappointed and let down if they stick to the GPU clock locking trick as the permanent solution.

---------- Post added at 01:43 PM ---------- Previous post was at 01:27 PM ----------

My reasons why I would or not choose a particular Tab

X98 Air 3G → YES Only the Dual Boot version because everything is balanced. The looks, the screen resolution, battery, SoC, XDA support. The only downside is the 32GB storage. 3D issue will be sorted out eventually.

X98 Air II → NO because it lacks cellular connection and GPS. You never know when you shall need 3G and GPS.

X10HD → NO over the X98 series because it is a little out of balance for screen resolution to battery capacity. I am no fan of 16:9 aspect ratio either but you get premium look and more internal storage than X98.

X16HD → Yes and NO over the X98 series because they look more premium and have got just the right required resolution. But I am no fan of 16:10 aspect ratio and 32GB internal storage.

Intel Core M → NO. Sure the performance is better but the price is expected to be in the range of Laptops i.e like 500$+

Thanks all - lovely tablet: benefits from WimBoot

All, I wanted to thank you for the great effort and comprehensive work done on helping us maximize use of this tablet.

The tutorials work very well, and I wanted to note that in a dual boot configuration (or single boot of windows) it's really worth converting your Windows 8.1 installation into a WimBoot install - this is used in the method described in the opening post, but in dual boot it's allowed me to compress my Windows installation down to less than 5GB installed.

That gives me a 8GB Android partition and a comfortable amount of space for Windows.

It takes a long time for Windows to do what it needs to to get fully updated, but once it's done, converting to a WimBoot doesn't take long and it really works well on this tab (or the Air II as I've used).

For more advanced users I'd recommend moving the default folders (my docs etc) to an SD Card, and also using junction points to move things like the Installer folder off of C.

Thanks again all!

maybe the gpu governor (if there is one) is not good as frequency and voltage are related, the in-between steps may not be stable enough. If we had custom kernel as android phone we could test voltage/frequence setps (and all devices do not react the same).
[Teclast X98 Air 3G] mcmaco:
Hello again,

QTx49 is a part of the intel drivers. Theses drivers are 32bits.

Sometimes windows has issues to run 32 bits drivers in a 64 bits environment. You could try to fix that with the compatibility mode :

see : http://windows.microsoft.com/en-us/windows-8/older-programs-compatible-version-windows

One reason of the crash might be a bad cable. Try another one (or/and another usb port).

My mistake for the teclast X98 there is no way to install rom by the sd. Sorry
