I'm really wondering if I should upgrade to Win10

Those who have done so, would you recommend doing it?

If I have the stock Win 8.1 with Bing and latest Bios (the Win key is not injected, but I have it), would you recommend using the Microsoft update?

Any other recommendations besides setting locale, language and everithing to US/UK to have an english Win?

Thank you very much. The growth speed of this thread is incredible! it's like 10 pages per day?
[Teclast X98 Air 3G] cosmok82:
tecknight, please read you this previous post...

The CH341A BIOS flasher is a 3.3v-5.0v eeprom compatible programmer, so, did you have already check that it works on 1.8v SPI eeprom too?

I don't want to burn my eeprom with a non compatible programmer, maybe it needs a "voltage level converter" to work properly. Is it?

At this rate my bus pirate 4.0 can work fine! ...with a level shifter...

Idea is good but we need to someone test it who has flash device ( in a case )

If reboot -p brick device then we can try halt -f ( this one restart device at once - not waiting for system )

Tecknight, I've been wondering: when are you getting your next article out?

Coming soon: Increase your available Windows disk space by up to 64GB w/o partitioning !!

I am looking forward to that as this is one of the most important thing for windows users on that tablet yet!

Thanks,

Hi guys,

I just thought I'd share the following with you.

I had windows 8.1 installed (dual boot) and I upgraded to windows 10. For some reason, I had to do it using the media creation tool as the automatic update would fail in the download process. Anyway. This being done, I had a version 10, activated. Yesterday I tried cleaning everything so I could use 100% of the space for Windows 10. I didn't want to go through the windows 8.1 install then upgrade - I wanted a fresh install.

As expected, I was prompted my windows 10 key... which I don't have. And the windows 8.1 key wouldn't work.

Well, all I had to do was to say "do this later" (or whatever is that small link saying) every time it would ask for the key. Eventually, the WiFi got configured, and Windows 10 activated on its own :eek:

I did some research, and it seems that the tablet "itself" got recorded at Microsoft as an activated device, and thus do not need to be reactivated. This is a relief - a lot simpler to go back to dual boot when Mirek's rom is finally out.

So, if you have Windows on the tablet, and plan on reinstalling anyway, then I recommend you first go ahead and activate your windows 10!

cheers!

Hi Tecknight,

Thanks for the work! I installed the 1.03 dual boot for the Air II (I have an Air II) and then installed your ROM. The still cameras do not work in that ROM, like with Mirek's v3 alpha.

Do you guys think Mirek's next release will fix this?

Thanks!

Cool, I came across this article/xda post today about Trojans in Chinese Android ROMS that spy on users and have custom update/payload systems imbedded in them have been found, and looks like from the article it was a big Chinese company Xiaomi/Mi.

http://xdaforums.com/mi-2/development/rom-gummy-nightlys-t2872413/post56249328#post56249328

https://blogs.mcafee.com/mcafee-labs/trojan-hides-rom-android-device

I now been wondering about is how can we trust these Chinese roms and has Mirek technically been de-trojaning the Teclast roms when he says in the build logs that 'all chinese apps have been removed'?

One thing that got me a tad paranoid about this was that Teclast came out with its new Android 5 rom right after Windows 10 came out and with everyone upgrading their Teclast windows tablets the new Windows 10 and Mireks ROMS it might of inadvertently squashed their spyware setup..

Thanks.

Hi there, I have a 32gb air ii. not the 3g version. I have the windows only bios from november or such.

I tried using the air 3g win10 package of drivers. I did not update the bios though.

Long story short : extremely laggy. bad performance all arounds which makes me miss 8.1. I cannot watch hd video on it anymore. At all. So maybe I have a wrong bios OR drivers, but right now, I do not like it.
[Teclast X98 Air 3G] cubelindo:
So no point upgrading to Win10 yet?

This "free upgrade to Win10" has some deadline?
[Teclast X98 Air 3G] siezed:
Good question, xaoimi's business model is different, they sell hardware at cost in order to distribute software so they might be more likely to include nasty spyware, but I def wouldn't put it past teclast. Spyware scanners almost never remove OEM spyware too cause its part of the contract when you purchase it, you have every reason to be suspect and careful what you use the tablet for, but pretty much all spyware is looking to gather use habits and what you're purchasing so they can sell the data to companies in order to build targeted ads instead of blanket advertising which is way less effective, ie they want to build a profile of you to sell to ad companies, its pretty unlikely it's stealing cc info or anything completely illegal like that from my experience, I worked in telemarketing for a few years and learned a lot about how spyware and targeted advertising works is the only reason I think this.

About windows - are you sure they not spying you ? It's completely closed c9de and you don't know what is inside . . .
[Teclast X98 Air 3G] jakep_82:
My experience is the same. I did a fresh install of 8.1 last night from the C8J6 factory image which includes all the original Teclast drivers. I then upgraded to Win10 through Windows Update. The end result is a laggy mess. I'm planning to do another fresh install of 8.1 and stick with it until Microsoft better optimizes Windows 10, or Teclast releases better drivers.
[Teclast X98 Air 3G] microb77:
I have the same version (Air II 32Gb) and Windows 10 works very well, better than 8.1. I think you may need to update your video drivers. I know in my case I installed the drivers, rebooted, it was the same... So I went in device manager, it was still "Microsoft Generic Graphics". Right-clicked it, updated driver, and it swapped to intel and was fine after a reboot.
[Teclast X98 Air 3G] mathsz:

Windows 10 in English (or other language but not chinese)

Hi guys, I've updated Windows 8.1 to Win 10 but most of text is in Chinese!

Before upgrading, I've installed Italian language pack to Win 8.1, but now it is in chinese! Any solution to get a clean English (or italian) clean installation of Windows 10?

Maybe could be profitable a *.BAT file (script) or a language pack available out of Windows Update..

Please QUOTE this topic :)

[Teclast X98 Air 3G] siezed:
What do you mean by clean installation? You can change the language of everything but there's a few steps, you gotta copy all settings over to Unicode to get rid of system Chinese and stuff but once that's done it should be all one language.

[Teclast X98 Air 3G] cosmok82:
be careful!!

Hi tecknigh, I read so much topics today about the W25Q64FW eeprom and I have to deny your info.

With the mix "flashrom + BP 4.0 + Level Converter" is possible to dumping and flashing the bios of Teclast X98!

I shall go one step further.

If you use a CH341A programmer without level converter, you can fry your Winbond eeprom. It's SO MUCH DANGEROUS, because the eeprom works at 1.8v of voltage level, instead the minimum voltage level for CH341A programmer is 3.3V!!

I pray that no one has tried this suggestion, it could works in one shot, but it might make the tablet unusable! Permanently!

For info.

You can find other info in italian FB group "Teclast X98 Air Utenti Italiani (Italia - Italy)", thanks.
[Teclast X98 Air 3G] grayfone:
There's not a way to cram all the steps in a single package or batch file, unfortunately.

That being said, the process is not hard. The parts that have to be changed are: input method (keyboard); country; non-unicode language setting. It's also useful to set the login page language as the same as main language (this will avoid the welcome screen in chinese...). If you alter all of those correctly, Windows 10 updates with the correct language, otherwise you'll have to install the language pack of your choice (by setting the input method to your language), then set country and non-unicode language settings.
[Teclast X98 Air 3G] Maxximo88:
Thanks for quote,

yep with clean installation I mean to get the original Windows 10 ENGLISH ISO (maybe made by Teclast) and install it with Pendrive USB, clean UP windows partition and install IT al NEW (but still Android partition available).
[Teclast X98 Air 3G] siezed:
Oh ok i see what you mean, as far as i know its more the key rather than the iso, you have a Chinese key, but with windows 10 u may have got an English key im not really sure, if you did get a us key it would be as simple as downloading the iso straight from ms with the tool, but my guess is its still a Chinese key. Doesn't matter as far as i now once you've changed the Unicode and system language its the same anyways.
[Teclast X98 Air 3G] Maxximo88:
Wait, do you mean Windows Product Key is linked to "Region" and not to the hardware?
[Teclast X98 Air 3G] svemm:
Hello everyone, I own an X98 AIR 3G 64GB Dual OS (Core Version: 5.008, Compliancy: Uefi 2.3; PI 1.2, Project Version: tPAD 1.07, Build Date 1/2015, Memory: 2048MB) which came with Windows 8.1 (English with some Chinese) and Android 4. I installed Windows 10 RTM Pro X86 English by plugging in an usb drive with the installer in Windows 8.1 and selecting "do not keep any data". The system appears to work well excluding the battery that drains up insanely fast, I see no 'question marks' in the device manager and I haven't installed any additional drivers.

Unfortunately I lost the multi boot menu and thus access to Android, the system directly boots to Windows (the C:\ disk is 32.8GB). Is there a way restore it (Lollipop preferred, but even the Android it came with would be ok)?

I've also been unable to activate Windows 10 with the serial key that i found in the ACPI/MSDM table in the BIOS by using RWEverything, it complains about "non-core edition ... run slui.exe to display the error", but this is a secondary issue compared to getting the multi boot back. Thanks to everyone that could help.
[Teclast X98 Air 3G] microb77:
No it is supposed to be linked to the hardware. It is possible that some metadata is recorded when "activating" your hardware, including the region of the windows 8.1 key on which you activated it...

In my case, I had installed a win 8.1 pro with my key, so everything was north america, and I activated windows 10... When I reinstalled clean, it was set to french canada.

So... it depends I would say.

Have your tried turning your tablet on holding volume up + and power ?
[Teclast X98 Air 3G] tecknight:
The reason I posted the particular CH341A flasher that I did is because we have had 2 successful bricked device recoveries reported using this specific flasher. I was not giving you detailed instructions on how to recover a bricked device, I wasn't giving instructions at all. I simply told you in general terms what you would have to do to recover your device. I told you to search this thread for specifics. I have not personally recovered a bricked device before, but all the posts I have seen use a flasher of this type at whatever voltage it puts out.

The bottom line is, this is your tablet and you need to decide what you want to do with it, whether that is trying to recover your device using the method that has been reported to successfully recover several bricked devices in these forums or using your bus pirate to try to recover it or tossing it in the trash bin, that is your decision to make

Hi, I have Teclast X98 Air 3G dual boot.

I just tried to update windows 8.1 to Windows 10.

During installation tablet powered off. When I tried to power it off, windows installation continues for about 2 seconds, and tablet keeps resetting. I can't do anything. I tried to use command prompt to reset into windows recovery mode, but i can't because tablet keeps resetting.

Android works flawlessly.

How can I repair this? Is there option to install Windows from USB, like in desktop/laptop computers?

I have read tutorial to install windows 8.1 from usb after selecting "Launch EFI Shell From filesystem device" option in bios, but after doing that will I lose dual boot option?

Tablet won't start

Hello,

My Teclast is C9J6. It was with stock Android and Windows 8.1. Today I received notification regarding update to Windows 10. I started the procedure. The tablet restarted and begun the update. During some point (I think in was installing drivers) it restarted and stopped at the red Chinese logo for several minutes. After nothing appeared, I pressed the power button for 10 seconds and the tablet turned off. Then I turned it on by holding Vol+ and Power. The OS selection screen appeared and I clicked on the Windows logo. After that the screen became dark gray (not turned off). It stayed like this for a lot of time. I decided to turn off the tablet again, by holding the power button for 10 seconds. And now it would not turn on at all. Any ideas what can be done?
[Teclast X98 Air 3G] tecknight:
I DID read it. You obviously did not read what I just posted.

I DID NOT AT ANY TIME TELL YOU OR ANYONE ELSE HOW TO RECOVER YOUR DEVICE.

I simply told you that you would need to get a flasher and test clip.

and to search this thread for instructions

-------

At this point I am sorry I even responded to your pleading messages.

I tried to be nice and explain what happened and empathize with your situation.

and now it seems you want to blame me when you, by your own admission, ignored the instructions in the tutorial and on screen to power off the device with the power button

Well at least I can say I tried.
[Teclast X98 Air 3G] siezed:
You should have left the red screen alone, the install takes a long time even on my high end desktop, it took even longer on my tablet and I remember it being on that screen for 10 mins or more, hindsight aside plug it in and let it sit for awhile then unplug and try different key combos, holding power then holding power vol - then power vol+ and -, might have bricked it though and need to try the unbrick procedure on first page which involves buying a flasher.
[Teclast X98 Air 3G] tecknight:

MFT doesn't seem to detect my X98 Air 3G C9J8. I have used tecknight's guide on both MHT and flashing, but it just stays there at "Ready to flash!" even though Device Manager in Windows tells me that Intel Android ADB Interface is connected.
[Teclast X98 Air 3G] siezed:
Well its linked to both, but the hardware can be changed, its stored on Microsoft servers and can be installed on a different pc and activated, but the key itself uses an algorithm with certain info in it, country and windows version are included in the actual key so can't be changed. Either way ms is way more lax with the keys now because they basically just added more problems for legit users while barely doing anything at all to prevent piracy, now you can use any windows 8 or 8.1 key on any computer and activate it, the limitation is only one activated PC at a time. Technically, while illegal and breaking the contract of your key, you could install and use the key on 1000 computers and windows would work, it just wouldn't be able to activate and would show a message all the time, but otherwise they'd all work normally. Instead of all the bs trying to lock people out, they simply ask you how many PCs you are using the key for, answer any more than 1 and it wont accept the key. The bios also has a home country imbedded and that's probably more why we can't go full English, even if we had a pure us iso and key.

It's not a Windows 10 problem. I flashed my tablet last night from a PC running Windows 10 with no issues.
[Teclast X98 Air 3G] tecknight:
I have as well. 4 or 5 times.What is happening ?
[Teclast X98 Air 3G] keloc:
Simply nothing.

I have used your tutorial to install MFT and everything went just fine. Then I downloaded two roms (the Lollipop you posted here and Mirek's v3.0) and ran MFT. I set up the values in settings, turned on the tablet into DnX mode, plugged it in PC and nothing happens.
[Teclast X98 Air 3G] tecknight:
Try running this as administrator

Download MFT timeout Fix

Do you see the X98 in Windows device manager when you connect it in DnX mode ?

If so, look at the details to see which VID and PID is showing

This is how it should look:
[Teclast X98 Air 3G] keloc:
Still nothing :(
[Teclast X98 Air 3G] tecknight:
Check my additional post above.

The tablet is in DnX mode, right.?

Not Droidboot mode ?

DnX mode=hold POW, VOL+, VOL--

Droidboot mode=hold POW, VOL--
[Teclast X98 Air 3G] mirek190:
In that case go straight to droidboot .

Press vol - and power for 7 sec then run my app that is with my rom and flash .
[Teclast X98 Air 3G] keloc:
Tablet is in DnX mode, the values are same as on your screen.

Your 5.0 Lollipop have only installer.cmd which are giving me errors "oem is not recognized as an internal or external command, operable program or batch file"
[Teclast X98 Air 3G] tecknight:
Try this, it's my last suggestion.

Close MFT.

Right click on the MFT shortcut on your desktop, select "Open file location"

Look for the file: CUSTOM_CONFIG.INI

Open the file.

Look for the line:

SkipXfstkPhase = false

Change it to:

SkipXfstkPhase = true

save the file.

Relaunch MFT

Select your XML file.

Then Boot up the X98 In Droidboot mode (POW and VOL--)

Once in Droidboot mode, MFT should start flashing

---------- Post added at 02:31 PM ---------- Previous post was at 02:05 PM ----------

OK, I tested it twice on my X98. Both times it flashed successfully with no brick.

By the way, reboot -p shuts the tablet down INSTANTLY.

Lowmemorykiller in 4.4 is far more better .
