brought tablet just for reading and study and for that its best. my problem is regarding gpu z showing 0 frequency. can you please confirm with x80h. I gave my x80h to friend so cant test myself.
[Windows 8 General] sbasil:
I don't have Windows currently installed on my X80h so I can't...Haven't used my x80h for a month or so. :D But I'm pretty sure that you not supposed to see the GPU frequencies since the GPU is integrated to CPU. If it's running Windows OK, I'm sure there's nothing wrong with it. Your tablet is just not powerful enough to run games at native resolution (too many pixels to push and not enough memory).
[Windows 8 General] teclast-x80hd:
Hello, i finally got the spi programmer, please can you help me out now?

These are the things i bought,

1: SOIC8 SOP8 Test Clip Socket Adpter For EEPROM 93CXX/25CXX/24CXX in-circuit programming on USB Programmer TL866CS TL866A EZP2010

2:Free Shipping CH341A 24 25 Series EEPROM Flash BIOS DVD USB Programmer W/Software&Driver(C1B5)
[Windows 8 General] ndouchin:
Pay attention that your programmer must have a 1.8 v tension, for not damaged the eeprom. It might work, but i bought one more expensive that your, to have the good tension.

I use the information of this blog to unbrick my tablet:

It is very simple.
[Windows 8 General] teclast-x80hd:
Thank you for the advise. I did see this website, but they talk there About the teclast x98 air, and they use something like the beaglebone black??

I have a teclast x80hd and i can not even find the right bios file for this x80hd can you help me step by step please??
[Windows 8 General] ndouchin:
I have made some picture of my x80h:

http://xdaforums.com/showpost.php?p=58763475&postcount=249

I don't remember where the eeprom is exactly. Do you already open your tablet? Put some pictures , in high definition of the pcb, if you want that i identify your eeprom.

However I cannot provide you a bios as my model is different from yours.
[Windows 8 General] teclast-x80hd:
Yes i saw your pictures, i think it is exactly the same.

[Windows 8 General] teclast-x80hd:
Please can you help me? The website talks About a teclast x98 and i have x80hd and i dont know how to do this, my tablet is now for more then 2 month offline
[Windows 8 General] ndouchin:
Without the correct bios i think you cannot be able to flash your eeprom.

Do you ask to your seller a copy of x80hd bios?

Or do you ask to teclast after sales ?

Concerning to flash your eeprom , you must choose a 8192 kB / 8MB chipset, and plug your spi programmer correctly. You have a keyed circle on your eeprom, to plug the cable correctly.
[Windows 8 General] teclast-x80hd:
I Think you are correct About the bios file, i used the x80h but i have x80hd tablet, i thought bios is the same, Lets say i have the right bios and i am pretty sure i plugged my spi programmer correctie, What is the software to flash bios? I used both manufacturing tool and the so calles CH41 i Think. But both dont seem to work, ho do i flash the bios?

A community spirit kind of guy would have pushed them into that onedrive location on similar.. :p I have a baidu account but it's still a pain, especially as downloads without that backdoor/rootkit manager are slo-o-o-w and unreliable.
[Windows 8 General] sence:
Sorry for not sharing that link in here. I dint think any one will be interested in this android 4.4 rom. Only change I could see in the rom is the addition of the new boot to window's switch(which only takes to that OS selection menu). I just needed this rom to see if it solves the bad battery meter issue. The battery reporting is different with different android roms. Even if you reflash the same bios or do a fresh install of windows, battery reporting changes only with the android roms. I got the file from one of the members of [MENTION=1167021]Hendrickson[/MENTION]'s site - techtablets.

X80h (FB5M)-双系统-Android4.4-V1.05_20150808版固件.rar : https://drive.google.com/file/d/0B7jPdolwYUQuSm5SV3ZTR2VBRUU/view?usp=sharing (This link is not mine, credit goes to the member Liam of techtablets).

Either way, I just wish you replied earlier, when you saw my request. Dint see any "community spirit kind of guy" when I needed one. :D
[Windows 8 General] Barleyman:
Thanks, I actually only started puttering with my X80H today so I haven't downloaded anything yet. As I said, Baidu = pain. I've got Weibo account which you can verify on UK phone but that ONLY works on the rootkit download manager. There's theoretically "log in with weibo account" on the baidu website but it does not actually work. At least on chrome and IE it does not. It goes thru the motions but actual login does not happen. Interestingly weibo phone confirmation thing only works on IE.

I have the 1.0.5 rom downloading on the rootkit manager now for what it's worth. I would've put it on my drive share, same as this guy did.. So does the battery charge meter actually work properly there? Would I be better served by sticking to LewaOS? My plan was to use Sbasil's tool to install 1.0.5 + strip chinaware + add GAPPS.

These one thread for one tablet threads get out of control pretty fast unless the OP guy is religious about updating OP..

I actually bought this thing for my son to play around with, I got Air II for myself.
[Windows 8 General] sence:
Mate, stick to the LewaOS or that Android 5.0 beta. This 1.05 is still not helping with the bad battery meter. Also there is a way to calibrate the battery for android (If you use only windows and wont switch OS, then this still works - http://xdaforums.com/showpost.php?p=57587321&postcount=3339). I did see slight improvements in the battery life after doing this. I dont know if you know this already, if not do it once.When the battery gets to 7% switch off the tablet. Then switch it ON and when the OS switch menu appears, touch somewhere on the screen so that the OS auto select timer will stop. Then keep that way until the tablet fully shuts down. Make sure no charge left in the tablet by pressing the power button again. Then charge it overnight. After that you will get kinda okayish battery meter in android.
[Windows 8 General] Barleyman:
Seeing how the data partition is 10GB for Android, I'd like to beef that up a bit..

Here are instructions for android-only installation:

http://bbs.teclast.com/forum.php?mod=viewthread&tid=263550

Has anyone tried that? Is the 32GB partition is safe to use, just replace the one in android rom and flash away?

Better to save the windows product key just in case..

..

Hmm, apparently that v1.0.5 fastboot installer bat killed Windows. Ahh, never mind, I never use windows 10 on my Air II either and this is for playing android games with. Lets try that 32GB partition table, what's the worst thing that could happen :laugh:

---------- Post added at 12:30 AM ---------- Previous post was at 12:15 AM ----------

Well didn't go to bootloop, that's good. Apparently there's still a backup partition stealing some 5GB of space but since the data partition is 25GB this way, that should be enough for some android games..
[Windows 8 General] teclast-x80hd:
Please i need help with my tablet
[Windows 8 General] Barleyman:
Well, as I said this is for my son to play with until he inevitably smashes it. At $100-odd I see this as a disposable tablet. Really great value for money of course. Personally I'm using Teclast Air II and my wife uses Ramos i10s. So the android version does not really matter as long as wifi etc works properly. Having battery stat giving heads up that "hey, you'll run out of juice in 20min, son" is of course important.

There's battery+ which you can use, it has it's own calibration routine so even if the built-in battery thing is broken, that'll tell you how much juice you have left. Well, I'm not sure in this case but on a reasonably functioning android it does.
[Windows 8 General] MacArthur67:
I also have a X80HD but no bios problems yet.

You must get the X80HD bios file. It's not available on teclast.com as far as I can see. Write an email to Teclast and ask for it: aftersales@sk1999.com, wangtt@sk1999.com

They answer but they are a bit slow. Write short and clear English as they probably use some translation software Eng -> Ch.

If they upload it to Baidu and link to it from teclast.com you can download it even without a Baidu account (may require a trick), or I can download it and put it somewhere else.

When you have the bios file follow this instruction closely: http://everythingisafile.com/?p=173

It doesn't matter if they talk about X98 as long as you have the right X80HD bios file. Use Windows 7 to get rid of the driver issues.
[Windows 8 General] ndouchin:
I have already say to him, to contact teclast.

[MENTION=5994621]MacArthur67[/MENTION] you can also backup your bios in android with linux flashrom utility (with static x86 compilation to avoid library dependency.):

http://ao2.it/en/blog/2014/11/21/teclast-x98-air-3g-cheap-intel-bay-trail-tablet-getting-acquainted

And before shared it, you can edited it in hex editor and delete the windows keynumber by replacing it by zero .
[Windows 8 General] MacArthur67:
Yes I know there are ways to do that but I have bricked my Android partition (problems with Exposed Framework) and currently waiting to get an updated Android to flash. Only Windows works fine in it now. Trying to back up the bios from the Win 10 side is just too much for me.
[Windows 8 General] ndouchin:
Poor "teclast-x80hd" user, he has no lucky with xda member which try to help him ^^.

Anybody else has the 80HD in android and can make a backup?

I have an X80HD and it runs well with Windows 10 and Android dual boot. I find myself using Android less, and would just like Windows. Can I use the following tool to create a bootable USB and boot off of it, to install Windows 10?

http://xdaforums.com/showpost.php?p=61067632&postcount=821

---------- Post added at 07:43 PM ---------- Previous post was at 07:31 PM ----------

I've been on Windows 10 since it was available, and haven't had any issues. Could it be the X80HD is more compatible than the X80H?
[Windows 8 General] billflu:
Just installed last night. I did have to follow sbasil's steps for creating the USB, as a regular bootable Windows 10 USB would not show up in BIOS. I backed up the drivers before re-installing. The only driver I had to seek out was the accelerometer, which was easily downloaded from the manufacturer's website.

Do you mean you are able to get Windows 10 only on the X80HD?

Is it possible to flash teclast's air 98 - Android 5.0 rom to x80h? (Same hardware/3735F)
[Windows 8 General] MacArthur67:
Absolutely not. Some hardware is the same (SoC) but much isn't the same, such as display, digitizer, eMMC, and so on. For example the X80HD boots on the KK fw for X80H but the digitizer gets mirrored somehow. But why do you want the X98's LP for X80H when there is a LP fw for X80H?

---------- Post added at 10:08 PM ---------- Previous post was at 09:17 PM ----------

If you ask me my X80HD is on that KK fw now (cleaned and tweaked). It's version V1.01_20150716., same version as my X80HD came with, the one I bricked with too daring Xposed modules. Now it's rooted and with Xposed installed again and only a few Xposed modules.

It turns out that Teclast don't have any later multi-language fw than V1.01 for X80HD, even though the Ch forums talk about V1.05.

Anyway, it works fine now. Cleaned and tweaked I get ~36k in AnTuTu and the highest reported score for any X80HD in Geekbench 3 at present.

Fast enough for my 8 year old son to play train simulator games on. It overheats a bit by 3D graphics games but I'll modify the cooling a bit like I did on a X98 Air.

I have the X80HD

After I ran Windows 10 update, my dual boot menu is gone. How can I get it back?
[Windows 8 General] billflu:
After a clean install of Windows 10, the only issue I am having is the vertical orientation of the screen. The screen changes to being upside-down when vertical, horizontal is fine.

Would someone be able to export all the registry keys under the following path?

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\ROOT\SENSOR\0000

Thanks!
[Windows 8 General] DanielDEV:
There is a LP for it? I have been searching for a long time.

Can you provide me the link/web for it?
[Windows 8 General] MacArthur67:
Yes, there is an official LP Beta. There are download links in this thread. Easiest way for you would be to go to page 79 in this thread and download sbasil's excellent X80H Toolbox, from which you can do everything you need. Download and install firmware, root, install Xposed, change screen dpi, etc.
[Windows 8 General] billflu:
I found the correct settings earlier in this thread. Applied reg fix and it was working after a restart.

Windows Registry Editor Version 5.00

[Windows 8 General] MacArthur67:
Can you still switch between Windows and Android if your tab is running one or the other? Have you done a BIOS backup? You can find everything you need in my post #1271 in this thread, including flashtools for both Android and Windows, but no BIOS file. I have a BIOS backup but it carries the fingerprint of my device and I would need to edit it to be able to share it.

My tab always boot in BIOS

My x80hd always boot into BIOS although I used to try many times. In BIOS, I see no boot option# but it auto boot in Windows installation when I plug a usb bootable with windows.

But now I can't boot into USB anymore but it still apears in boot option#. I have tried install Android with 4Gpartition via Manufacturing Flash Tool and it success, but still auto in BIOS.

What can i do now? Have I flash DualBIOS again? Is there anyway to flash BIOS via fastboot mode?

Flash the dual boot bios again using Android and you will solve :)

Should we see an update to lollipop on this device ?
[Windows 8 General] mr_kaboom:
I think i understand. But everytime i hit the power button, it always boot to bios (with mono color like blue and gray, there are 3 tab Main, Boot and Save&Exit), no box to choice Android or Windows.

To day, i disconected the battery and hoping bios will be reset. After about 5-6 hours, I connected the batterry. When I connect a usb bootable (with Windows 10 installation), it show a Android 4.4.4 install (or pre-setting) with text "please wait" - or something like this, And it boot to Android successfully. Unfortunately, the touchscreen didn't work correctly, so I stupidly power off-and turn on (because I think it will be okey after restart) and forgot update the bios. Now, poor me, it just always boot in bios.

How can I boot to Android again to flash bios? Please help me!!!

[Windows 8 General] oile:
No problem then :)

Flash android following instructions (intel flashing tool) and then reflash dual boot bios within android (I remember I used the flashing tools from x98 to flash our firmware but if I don't mistake someone uploaded here these files too).

After that you will be good
[Windows 8 General] mr_kaboom:
Did you mean UpdateIWFI.apk file. After disconect and reconnect battery agains, I can boot in Android and install this apk. I already copy the backup BIOS from another in this topic to the sdcard of tab.

When i run this apk, choose the .bin file and hit the Update, it run and stuck at "Upgrading, this may take a few minutes".

Have I root this tab before upgrade bios? I have not yet did this step.

Can I stop this process and root it now with out brick it agains??? :(

Update: Many thanks, I just backup and flash bios with X80H toolbox 7.4

But when i turn off and turn on, it boot in bios agains, so I flash the Android 4.4 (from a man-him said that is stock rom) with Manufacturing Flash Tool. The process showing in desktop is ok, but the tab showing 2 errors. First it said "EFILLINUX ERROR... bla...bla. Dis DNX mode?". And after flash recovery successfully, it showing a error on tab's screen "Could not open /sys/devices/virtual/backlight".

So Can it be cause of why it always boot in bios? (because i flash wrong rom?)

Sory for my bad English.
[Windows 8 General] dr.diggler:
I had this too. I Used Toolbox to flash Android, not intel manufacturer flash tool. Worked fine for me. But i don´t know if there is a possibility to flash x80H(D) too with that toolbox.
[Windows 8 General] mr_kaboom:
As you say, did you use X80H for flash? It work fine - sound like it boot to Android nomally?

So my problem with bios is the error "EFILLINUX ERROR... bla...bla. Dis DNX mode?" or the bios chip is working badly?

OMG, this is my second X80HD tablet. The first was bricked (or damaged bios) because I tried to install windows 10 64-bits and in my country, i can't find anyone who can flash this bios chip. They have a programmer, too, but can't read the chip.

Can you give me a link for a official rom for my X80HD., please. I found some at Chinese Teclast forum, but can't download because i don't have a baidu account. I used to create a new one but can't pass through captcha after activate with link in Email.

Heat sink mod

I did some DIY with the cooling in my X80HD. It used to overheat and throttle the performance quite a lot when my son played car racing games on it, but not any more!

All it took was 2 x copper heat sinks (shims) size 15x15x1 mm (CPU + NAND) + 1 x copper shims size 10x10x1 mm (PMIC) + thermally conductive adhesive transfer tape + heatsink plaster + 1 hour work. The original cooling was just some heatsink plaster between the CPU + PMIC and the metal shield plate. That's obviously not enough. There was no heat pads or anything on the NAND or the RAMs but I put a copper shims on the NAND and transfer tape + heatsink plaster on the RAMs anyway. Temperatures are down more than 10°C in the same stress test and the score in 3DMark is up ~10%. I did the same mod on a X98 Air 3G before and it had even greater effect there, probably because of the metal backside of the X98. Total cost on AliExpress for enough shims + tape + heatsink plaster to do the same mod on 15 tablets is less than 10 USD for all including shipping. Se attached photos for details.

Hi guys, I need a bit help on checking whether I screwed up my mouse drivers or not :(

simply put. Could you guys unplug the usb mouse if it is plugged in, then check whether you still have the mouse icon on device manager like the image below ?

https://dl.dropboxusercontent.com/u/99592042/mouse/youhavedis.JPG

Also, could you then check the mouse property on control panel and see if there is anything there like below or not ?

https://dl.dropboxusercontent.com/u/99592042/mouse/nomouse2.PNG

I'm asking this because I discovered some games (The Legend of Heroes: Trails in the Sky, Stein;gate) will first check if any HID-complaint mouse is attached or not. If no mouse attached, then the game will simply ignore ALL touch screen attempt, and I can't do anything to the game. On the other hand, if a usb mouse is detected then the touch screen will register into the game, despite not actually using a use mouse at all.

And i am wondering whether this happens to everyone , or is it just my Teclast

Thanks guys
