Touch screen android doesn´t work

Hi, any knows news about touch screen android failure? , I have teclast air 30 c8j8 and it doesn´t work since two months, i changed roms but nothing, thanks for all.
[Teclast X98 Air 3G] kosmas fil:
I put a different model. mine is c8j6 and I'm downloading for the c9j8. I believe it will work and they seem to be downloading... well see.

by the way what is the difference between these versions?
[Teclast X98 Air 3G] salespalace:
just bought two 64gb versions of the x98 air 3g from geekbuying. how much faster is its emmc compared to the 32gb? and it their a sort of guide on what to do when i first receive the tablets?
[Teclast X98 Air 3G] kosmas fil:
the new ones that arrive are working fine. Check the camera on bot os if it is inverted and apply the fix if needed, change the language the one you prefer, and root android in order to remove the chinese apps. (see page one)

one more thing. Do NOT touch the partitions (you'll see quite a few if you go to storage management in windows) for any reason. they are all needed by android.

It is fixable, but it is a hussle. just in case download (why not today) the firmwares for your device. A backup is also advised
[Teclast X98 Air 3G] salespalace:
thanks for that.

will most fixes that were originally made for the 32gb version work with the 64gb version?

I have similar keyboard meant for iPad Air. It fits well and yes you can use the Cmd key as Windows start up key. The BT works really well. The Only problem is that there is no Esc key. Instead of that there is Home key, but it does not work. The Home key in Windows takes you to Internet Explorer.

Unregistered Device SB.PCI0.XHC1

Hi,

I've tried a lot of drivers and my sleepstudy now shows only one major offender: Unregistered Device SB.PCI0.XHC1

Anyone knows how to solve this ? I've tried to disable USB Hub and nothing changed. What device is this ? Why it is "Unregistered" ? My Device Manager is fine, without any exclamation marks or apparent issue.

Thanks !
[Teclast X98 Air 3G] ZeAuReLiEn:
A Google search on the device name suggests that it is related to "SB xHCI Compliant Host Controller"

Do you have anything plugged in on the USB port ? A MicroSD Card ?

I don't have the tablet yet (ordered a 64GB Dual Boot), which means I don't know if I'll face the same problem

WiFi performance in both Android and Win10 is about 15-18 Mbps at best (should be at least 30Mbps). Since its in both operating systems, it does not seem to be a driver issue.

Is this malfunctioning specific radio or typical for the device by design? Any reference?

i'm trying to install windows after android for dual boot. it was from the beginning dual boot so the bios is ok. android installed and running ok. i place the two sticks and start the installation but in that cmd window it gives me a messege "failed to make w:\recycler\scratch directory" any Idea what goes wrong?
[Teclast X98 Air 3G] ZeAuReLiEn:
I faced this issue with another tablet, that was because there were remaining partitions on the disk that caused partitions that were supposed to be used for Windows (one for data, one of few GB for the OS image) and the installation scripts didn't map properly the W:\ drive

I sorted this out by cleaning partitions (carefull if you want an Android dual boot) and manually following the .cmd script to ensure W:\ was mapped properly

Good luck

Trying to upgrade to Windows 10.

Deleted the Windows 8 partition.

Tried to install but it said something like "win could not create a new partition or locate an existing one"

Deleted the last partition of 5gb, like I found in a post.

Then I get another error> Unexpected error, verify that sources are accessible. Error code 0xC000005

Also, before that, I get a "Partitions on the disk are not in the recommended order"

X98 versions ?

Hi everyone, I've just received my X98 Air 3G Dual Boot 64 Go, and this is version C8J6 (when I look in Android's parameters)

The point is the AliExpress' seller said on the description page that all the X98 Air 3G sold will be on C9J8 (the less buggy version I guess)

So before going further in development and hacking, is this C9J8 real ? Anybody have it ? Because in that case I could open a dispute with the seller.

Thanks for any information !
[Teclast X98 Air 3G] Petepe10:
It supports 11n 2.4, not 5 Ghz. What is your negotiared connection speed with your router. I get a 28Mbps speedtest when connected at 65Mbps. Orientation of the tablet plays a role as well as how busy with signals your area is. Get wifi analyzer from the Play store, could help to find a less busy channel for your router.
[Teclast X98 Air 3G] Dadaism:
The 64GB Dual Boot Version is C9J6, that's what mine said before I flashed Mireks custom Rom.

However, mine is still suffering from severe battery drain under windows 8.1.

I noticed when changing Critical Battery Action under windows to 'do nothing', the capacity increases a bit over 41k mAh (before around 31k). How is this related (shouldn't change the real battery Voltage)?

I noticed that when I switch between Android / Windows, the battery calibration is messed up again and battery is stuck at 7%. Although I fixed it under Windows.

Under Android, I seem not to be able to get rid of the stuck at 7% battery. I deleted batterystats.bin / recalibrated the battery, but nothing seems to fix that. Any Idea?

Build 10036 setup touchscreen inverted

I downloaded the new Windows 10 Build 10036 which was leaked by TNSC then converted the build to 32-bit Enterprise using the svfx tools leaked by WZor then extracted the iso then I Integrated the drivers into both images in boot.wim and into the single image in install.wim then I copied the files to a usb flash drive previously formated with rufus and also copied the drivers on to it just in case. In perivous builds of windows this allowed me to install windows without a usb hub just by using the touch screen. Anyway, then I entered the bios of my tablet by pressing esc on the touchscreen keyboared the flash drive was in the tablet. Then I booted from the flash drive, but this time the touchscreen didn't work during setup. I then tried do integrate the touchsetting.gt and that produced no result, then I expiremented. I unpluged the flash drive pluged in a mouse, the mouse worked, then I touched the screen and the mouse pointer disapeared and a touch pointer appeared on the oposite side of the screen (it was inverted) I moved the pointer to the next button but I couldn't press it so I was unable to complete the setup (I couldn't use the mouse because I have no hub and the mouse would have to be connected at the same time as the usb flash drive)

I used DISM but Wintoolkit and ntlite use DISM also, so I probably would have gotten the same result if I used them. Does anyone know a possilbe fix? My guess is that this is broken in build 10036.

[Teclast X98 Air 3G] BoORDeL:
U do not really need that app to change GPU frequencies.

Are you rooted?

Yes follow this method:

If you want a persistent fix, also after reboot you can create new file install-recovery-2.sh file and put it in ./etc folder with these istructions:

#!/system/bin/sh
echo 400 >/sys/class/drm/card0/gt_min_freq_mhz
echo 400 >/sys/class/drm/card0/gt_max_freq_mhz

I prefer 500 as max freq... but you have to test it.

No: ask for TECLAST SERVICEDESK help.
[Teclast X98 Air 3G] vpx:
Same as me:

1) delete 5 GB recovery partition on the almost end of drive. You probably ran diskpart. Done.

2) in diskpart delete Windows 8.1 partition.

3) create new partition (size is old Windows 8.1 partition + recovery 5GB partition = cca 18 GB)

4) format this new partition as ntfs, quick (diskpart)

5) assign letter to this partition (diskpart), make partition active

6) download gimagex from autoit web site, put it on the same flash drive, where you have Windows 10 installation.

7) run command line in Windows 10 Install (PE) key F10, locate and run gimagex, locate install.wim image of Windows 10 and apply that image
[Teclast X98 Air 3G] lion_sta:
Thx for the reply,

what I did and it worked is format the entire disk, apparently, since I couldn't find the specific partition, but I don't think it is a problem since I haven't opened once the Android.

Then the install worked after changing the disk to MBR from the command line.

It seemed to work fine.

C9J8 Bios v1.03 Download Link

Dear All,

I've been reading hundreds of pages of this thread and I really think that some of you that provide solutions are heros to me. I my self have fixed a C9J8 to then sold it to my customer. Thanks to the heros who have written this thread.

But I have another C9J8 that is "stubborn". It came dual boot with Bios v1.03. I have no problem starting the Windows, but everytime I start the Android, it always comes to the screen saying "Entering DNX mode. Waiting for fastboot command..."

I've discussed this with the seller. As they suggested, I've download C9J8 stock installer right from teclast.com/tools/pad/pad.php. I've ran the procedure carefully for several time and always stuck at 10%. After waited for a while, Intel Manufacturing Tools said, "#0: Device on port 0/0/4 #0 timeout to enum adb (TIMEOUT = 180)."

I've also have tried first page's tutorial regarding "stuck at 10% problem", but have no luck either.

May someone here help me to solve this problem?

Oh, and Anna Fang from Shenzhen OKQI Electronics Mall at AliExpress.com, if you are in this thread, "thank you" for sending me two broken units of C9J8 in one delivery. What a big coincidents, huh? I really think you've sent me reject items. May my money makes you more "prosper".

Friends, please help me fix the problem, thanks!!

Hi all, just got myself one of these and fell into trouble very quickly.

As a few others have done, I changed a setting in the bios and bricked it.

I've ordered the required programmer pieces from eBay. [MENTION=1167021]Hendrickson[/MENTION], can you confirm whether your tablets had the W25Q64FW (this is what I have) which is supposed to operate at 1.8v and not the W25Q64FV which operates at 3.3v?

I bought the same programmer/test clip as you have so just looking for confirmation that I won't need any voltage stepper.

From the searching I did, it seems they should be fine and only one post in this thread about being careful with the voltages (later edited stating that he desoldered the chip and may have damaged it during that process). [MENTION=1167021]Hendrickson[/MENTION] sorry to point you out but I've been following you on YouTube specifically because of your great videos on this tablet, keep up the great work!
[Teclast X98 Air 3G] Hendrickson:
I can confirm my one was the 1.8 volts W25Q64, I was really worried about frying the chip to. But I plugged it on (With the battery attached) I heard the Windows new hardware beep and it was detected. Flashed it and no problems, It brought my X98 Air C6J6 back to life. I later sold it as the touch screen was laggy.
[Teclast X98 Air 3G] Paulicat:

Love windows on these tablets, but I only got to use it for 24 hours before bricking it!

detecting GPS on teclast x98 air 3g Win 8.1 (not dual)

Hello Folks

Just purchased the above BECAUSE it was advertised as having a fully fledged GPS. None of the navigation/mapping apps (mine or pre-installed) can detect the GPS. The purpose of having this kit is to use it for GPS marine navigation. No use (or much reduced use!) without it. Read most of the thread and my conclusion is root-cause of the problem could be a number of things, from BIOS version to Win 8.1 drivers.

No a tekkie at your level guys, so would appreciate your advise on: (1) how to correctly diagnose the problem, and then (2) how to fix it! I'm sure someone on the forum has already encounter this problem.

Many thanks in advance!

As far as I know, installing Xposed on the tablet will cause a bootloop. I haven't seen any fix yet to get Xposed working.

If you installed the newest Xposed apk, just press the vol+ key repeatedly while android is booting. That will trigger an auto-deactivate of the xposed framework.
