Remember that the problem was not the tablet, the problemas was a SERVICE of windows, the teclast x98 works perfectly without issues :good:
[Teclast X98 Air 3G] MindlessAutomata:
You can't really say that. Not everyone gets the issue, and the people that had it on windows 8.1 also got in on Windows 10, so this would all point to some sort of issue with the tablet. It's possible sensors are reporting incorrectly, or there's some voltage issue, or the tablet has inadequate heat dissipation. When I opened my tablet, I did NOT have the metal shielding over my SOC that is shown in some of the other guides for adding copper plates to bring the temps down.

It's likely there is some hardware irregularity of some sort that is causing this service to shut down the tablet.
[Teclast X98 Air 3G] Aviver:
Can someone recommend one external flasher for my bricked teclast? Thx
[Teclast X98 Air 3G] siezed:
Yea you're exactly right, Ive always suspected cheap sensors that fault easily, every time I run hwmonitor I see 400c + under max temp but I never see when so its just a Ms glitch to that high which could be related.

Also guys remember the soc is rated to 100c but heat drastically reduces screen AND battery life, heat can wear pixels and basically destroy batteries so make sure you watch temps if you disable the thermal shutdown.
[Teclast X98 Air 3G] ILUVMONEY:
Thank you for the info. I was in the middle of downloading windows 10 through the medial tool and my Teclast rebooted. Everytime I start windows, it always reboot once for whatever reason. I have also upgraded the bios to 2.02 and still does that Well, I hope I won't have to install those drivers manually after upgrading.

Another question, I can install the 64 bit version windows 10, right? The selection was in Chinese, anyone knows if it matters if I happen to choose the N/pro version or not?
[Teclast X98 Air 3G] MindlessAutomata:
NO! Everyone who has done it has bricked or messed up the windows partition, one of the two, I can't remember which. Don't do it, the BIOS is only 32 bit and since there's only 2gb of ram on these 64 isn't really all that necessary.
[Teclast X98 Air 3G] ILUVMONEY:
Thanks!

Oh wow I didn't know that. Good thing you told me! Thanks man/lady!
[Teclast X98 Air 3G] sandroj:
How did you download Win 10 directly? Is it necessary to save the key if we update this way? And do you mean that all the software needs to be reinstalled?

Do MS have tools in order to know this kind of problems? Or we should contact with them explaining the problem ?

Go here:

http://www.microsoft.com/en-us/software-download/windows10

Make sure you download the

32-bit version

despite our 64-bit processor (runs in 32-bit mode).

[EDIT: if you are going to run the tool on another PC that is 64-bit to create install install media, D/L the 64-bit version....later in the creation process you should select the 32-bit version of Win 10.]

On a dual boot model, if you have at least 7GB free on your tablet's C: drive in Windows, you can download the 32-bit tool to your tablet and follow the direct upgrade procedure. On my 32GB X98 I couldn't get much more that 5GB free. If so, you must download on another the tool on another PC and create install media, either on a flash drive or SD card of at least 4GB size. If you format the flash drive GPT, you might be able to boot with it. Most have not been able to get that to work. If so, do what I did and just boot normally into your tablet's current activated Win 8.1 and access the flash drive or SD card there and run setup. You don't need the key even if you have an updated BIOS with no key. As long as your current Windows is activated, Win 10 will be.
[Teclast X98 Air 3G] mikbe:
No no no. If you make the bootable flash drive on 64-bit Windows, you should download the 64-bit version of the tool.

The tool will ask if you want to download 32-bit or 64-bit image or both. I choose both so that I can use the same flash in all my computers.

I had only 5,5 GB free storage and Windows 10 installed just fine.
[Teclast X98 Air 3G] kosrica:
It seems I cannot change the GPU frequency in mirek's v3 lollipop ROM. I've tried the standard commands in terminal emulator and I've even add the script in install-recovery-2.sh. It seems that the GPU frequency stays the same at 646 MHz. Any idea how can I change the default frequency? Is it safe to directly modify the android files gt_max_freq_mhz and gt_min_freq_mhz?
[Teclast X98 Air 3G] articsilverfox:
If you haven't done it your self then I don't recommend you suggest it, so far everyone whos attempted to install 64bit Windows 10 on their Teclast has bricked it according to this post.

[Teclast X98 Air 3G] mikbe:
Where exactly did I say that you should install 64-bit Windows on X98? Nowhere. I said you should download 64-bit tool if you create the bootable flash on 64-bit Windows. Tool then asks which type of Windows you want to download. And that should be 32-bit for Teclast.

Despite all the warnings about voltagelevels and the possible resulting damage i took a gamble with it as my Air II was dead anyway...

Ordered a generic c341a and a test clip off ebay and they worked very well without any modification.. My tablet's back and running windows 10 :)
[Teclast X98 Air 3G] mirek190:
I have a trouble with system ui - even repacking that brakes notification panel position ( to the left - not keep in the center )

In that case I remove extra buttons later( vol + - ) when I find solution .

Xposed I add later in next release ...

I have exta idea how to save even more Than 150 MB of system ( system will be even lighter and faster ) but it takes a week to finish - then it will be v6 [emoji12] and add more features ....

Now I'm uploading v5 ....air3g and air 2

For everyone who updated to win 10 and it seems a bit laggy... I changed a simple setting, maybe it is known for many of you, but just in case help to anyone... Go to Settings /accessibility /Other options... disable visual options (first option)... It help me and the tablet seems to be better.

Yes, you're are right, it's possible a bad sensor or something else.

It will most definitely work on C9J8 and C5J6. Just as likely camera won't work on C6J6. But who needs the rubbish camera anyway. :silly:

MA is correct, it NEVER ends well if you try to install 64 bit windows !!

Thanks a lot for all your hard work, Mirek!

Do your new builds work on Air II variants too? Specifically, I have a HG9N model... Your v3.0 build works fine there, including the cameras, does it mean v4.0 will work too?
[Teclast X98 Air 3G] mikbe:
It's always the same when new ROM is about to be released.
[Teclast X98 Air 3G] billbmsn:
Fair point - making sure the final Win 10 OS download is 32-bit for our tablets and not the tool itself. That's what I should have said. I'll correct my post.

So, I gather you were successful installing Win 10 as an update directly to your tablet with only 5.5GB space. Maybe I was just shy of 5.5. I tried several times and the process failed near the end and I recall seeing a disk space error. Also, were you able to get an English version of Windows doing this? The reservation update method installs Chinese Win 10.

If you can get enough free drive space to update directly and you end up with English (or whatever language you want), this is a likely much faster method than using a flash drive or SD card like I did, but I couldn't get it to work.
[Teclast X98 Air 3G] mikbe:
Somehow 32-bit version of the tool didn't launch on 64-bit W7 Pro. I was wondering this too.

I updated on battery power without reservation from 8.1 Pro -> 10 Pro using USB flash drive. After installation there was much more space available than before.
[Teclast X98 Air 3G] billbmsn:
Mike: I edited my post while you were replying. Oh, and now I understand that you used a flash drive. I thought you were saying you could update directly to the tablet, no flash drive or SD card involved, with only 5.5GB free. That I believe requires more like 7GB, as I wrote.
[Teclast X98 Air 3G] fresnillo:
sorry but i cannot understand why

Sorry for ask at this way but the question is simple.

How the users have been installing an iso of W10 x64 and has bricked the tablet?

It's the first time which an OS flash the BIOS? Or the brick is simple and can be undone when reinstall process finished?

I want to clarify this because it's weird when you read that a windows x64 instalation has bricked a tablet, which can run any SO from UEFI and has a BIOS with a "launcher", and the tablet has a x64 CPU.

Thanks
[Teclast X98 Air 3G] mikbe:
That for me too felt impossible to achieve so I decided to install it from flash drive.
[Teclast X98 Air 3G] cashif:
Could you please post the detailed steps to upgrade to Win10 and clarify my doubts. I already have prepared bootable flash drive; I have two doubts 1) Will updating wipe my android partition & 2) Does the flashdrive immediately gets detected when Windows restarts during install.
[Teclast X98 Air 3G] mikbe:
1. Charge the tablet

2. Plug in flash drive in Windows

3. Launch x86 setup.exe

Bing is Home and Pro is Pro. That's it. If I remember correctly I unplugged flash drive and plugged in charger after first restart. It only needs flash drive to load files in internal memory. Yes the update folder is created in C:\ even if flash drive is used. If battery is full when update starts, this last part is not by all means necessary.

And no. Updating won't wipe your Android partitions.

You rebooted once after flashing? Many devices require that. Instagram has never worked on my C6J6. It must have something to do with the camera.

Have you made clean install ?

Do you have problem with GPU ?

Because all system is accelerated by GPU

Try reduce speed gpu / system/etc/init.d/gpu-fix

Change from 640 to 550 or less and then try .

Because now all system is accelerated by GPU even stock 5.0 is not.

I tested 4 days and rom was fully stable for me..

Hi Mirek

I have a problem of flashing your ROM v4. First, I tried flashing with your file "FLASH_tool_Teclast_x98_air3g_and_air_2- (v2.1) .bat" but I met the same problem as "yotiXD".

So I tried with MFT, but MFT hangs at 11% then the program closes (see the MFT attached picture) and now more way to launch Droidboot only DNX mode works.

Restarting normally my C9J8 hangs on the picture Teclast then nothing !

What can i do ?

And restart pc after that.

If you use my tool in android you need swith on developer and usb debugging.

Or go straight to droidboot by pressing vol - and power for 7 sec .

All driver was installed, I just manage to restart droidboot (4 try) but the flash with your file .bat stuck on "waiting for device" and nothing ...now i can't launch android at all.

Typing this from your new ROM mirek :D thank you very much, I just wanted to report that I also got a random lockup right after install, first thing I did was run antutu, it went fine then when I tried to click results the app froze, I force closed it then reopened and that's when the whole system froze, but I hard restarted, ran antutu again and played 2 games a of vainglory then typed this with no lockup so idk what caused it. The other small issue is the volume seems wonky, its kinda like either full volume or mute, probably a setting in viper but just thought I'd let you know, thanks again!

Edit: seems to only be system sounds like touch sounds and lock sound that's unaffected by the volume button, but a google search makes me believe its an android/lollipop issue that we've had for awhile and never noticed because the volume was so low to begin with and viper brings us up to near normal volume so its noticeable, still haven't found a fix though if anyone does let me know☺

Teclast X98 Air 3G Tablet: 9.7&quot; 2048x1536 px - Z3736F - 3G - Android/Windows...

I updated to Windows 10. Everything went on smoothly and Windows 10 is in place running with lots of lag, may be due to driver which I could not install till now.

Now the problem

The tab is totally in Chinese excepting the apps which are partially in English. The SETTINGS menu is painfully in 100% Chinese and I am unable to do anything. Can somebody come to my rescue. A video guide would be very helpful. Incidentally, it may be said that my windows 8.1 was in 99.9% English excepting occasional one or two pop-ups with partial Chinese. So I could not understand as to how windows 10 was installed in Chinese.

Thanks to everybody in anticipation.

x98 Air 3G C5J6 in a complete mess, please help

Hi I need help! Would really appreciate if you could suggest how I could fix my only tab the x98 Air 3G C5J6.

I earlier upgraded to Win10 but found that I'm not able to connect to 3G. It just wouldn't allow me to proceed after keying in my pin. I thought maybe the upgrade corrupted some drivers so I wanted to start clean and reset Win10. In the midst of resetting Win10, it rebooted itself and gave me this error 'INACCESSIBLE BOOT DEVICE'. No matter what I do, it just wouldn't boot into Windows. So I created Win10 USB boot device and booted from it. I entered Win10 recovery and tried to reset again. Still wouldn't work. So I decided to reinstall Win10. Along the way, the Windows partition got deleted. So I tried installing Windows in the unallocated disk space of about 33GB but it just wouldn't proceed.

So now I'm stuck with a device that still has Android working, but Windows completely gone with seriously messed up partition.

Is there a way I can restore my X98 C5J6 back to its original factory state from the recovery partitions?

When resetting Win10, I didn't expect that the process will screw up so I didn't check the CD key. I’m not able to check my CD key now since my Windows partition is wiped out. If I were to follow Hendrickson's tutorials to install dual boot, Android and Windows again will I lose the CD key currently embedded in BIOS?

One of my major worries is that I believe my partitions are seriously messed up now and I probably need to do something change it back to its original state.

Desperately in need of help.

Mirek:

I flashed your new 5.0 V4 successfully to my 32GB Air II. Sure like the look and feel, but...

Every other boot or so, the wifi icon on the home screen shows an exclamation point. I have had no issues with wifi prior to this. The connection status show 72 mbps, but things seem to download very slowly.

The cameras are broken and Skype locks up. Never had that problem with your KitKat ROMs. I tried a few other camera apps and nothing worked. I use this tablet for Skype, so I guess it's back to KitKat V4.2 for the time being.

Antutu locks up at 1%, even after multiple reboots.

These both require a shutdown.
[Teclast X98 Air 3G] G3n3R4L:
Flashing the new bios doesn't harm any os, but i think you already lost your windows cd key .... If you already loat your installed windows
[Teclast X98 Air 3G] Luigi.:
Yes, i used the path, which the utiliy installer choosed.

update: successfully

i have done many different things at the same time, so that i do not know which was teh solution

1. installed BIOS Utility to root c: (only an folder with 1 letter)

2. kopied the Key.bin to the same folder like BIOS Utility ((only with 1 letter: k.bin)

3. run as administrator

3.1. choose the 2nd Option

3.2. chose the k.bin and do not mark the point under the k.bin line

3.3. forward

4. the the tablet boots only one time, after reboot, no popup window at the BIOS Utility

5. i am very happy, now can window 10 come... :)

Best regards
