    How can I get the SOC devices and Android devices VID and PID? Are they different for each Teclast X98 tablet? If they are same for all devices could you write them up here?

      In the “ManufacturingFlashTool” tool use the Help command to get a help document. You will find your answer there.

        My device is detected as Intel Android Composite ADB Interface so I can get the Android devices VID and PID. But I cannot obtain SOC PID/VID, according to the manual I need to connect a device in SOC mode via USB cable. How should I do this, I tried some ways but can’t find any new device under Intel Soc. Did you manage to do that?

        Reply
          • jachas

            OK, I did it :)
            SOC devices VID 8087 PID 0A65
            Android devices VID 8087 PID 09EF
            Then open flash.xml
            Power off your tablet. Hold volume up volume down and power button as long as you see the Teclast logo. The screen should stuck on this logo. Then you have to plug it to your USB port, it should be USB 2.0, for me USB 3.0 didn’t work out. Device should be automatically recognized and flashing should start from now on. Then just follow the next steps in the guide here. GL :)

            Thanks.

            For some reason my device gets stuck on “Booting to droidboot.img success”:

            Maybe someone else will have know how to resolve this.

          • jachas

            What is going on with the tablet then? Is it restarting to the droidboot screen? If so, what information can you read on the bottom left corner? Besides can you read and provide the information about your VID and PID when you connect the device just stuck with the Teclast logo and how is it recognized (name in device manager)?

          • Tom

            At first i have put it in the soc mode like you described to get the vid and pid. I have connected the tablet to my pc and it apeard under the intel android phone in device manager (the same place as with tablet running androig os and debuging mode enabled) but this time PID was different. So I used those values and placed them in SOC section of the flashing tool along with allready obtained pid and vid from debugging mode. Then i have put the tablet in soc mode (stuck on teclast logo) and connected it, flashing tool recognized it and began its work.Tablet
            simply shut down and never booted, all i saw was a black screen.
            Oh well. By your small review I am not so enthusiastic now 😉

          • jachas

            I had the same problem and I remember I was just doing some tries with those PID and VID numbers. I’m not really sure and don’t want to confuse you but probably my SOC devices PID and VID are from the device manager when android run and Android devices VID and PID when it stuck on Teclast logo. If I remember well when SOC devices VID and PID are correct then tablet boot to bootdroid (screen with blue android robot in the middle) but with some errors and stuck there, provided Android devices VID and PID correctly let you finish the operation successfully. But think twice, I would stick to android if I know how is it working on Windows 😉

            jachas please send me PM whit your email, i install windows 8.1 but i have question about settings in BIOS. thanks

            nie uzywam fb więc nie wiem jak się z Toba skontaktowac.

            odnosnie tego kroku to nie pamietam dokładnie, ale ja tez malem jakis problem jak źle odczytałem te całe PID czy VIDy

          • Mary Web..

            You.. I did. had the same error. I installed windows 8.1 no screen touch so I flashed back to Android. yet I was stuck at INTEL INSDIE that is ALL it did. I played with . the O65A and the other one. When I shut off after I tried to flash with intel flashing tool. I would unplug it then back it. Check numbers (o95a something like that) I would put that in then just reload the “flash.xml” and this time it flashed the droidboot and was on that screen on my tablet. I then just watced the video 222.swf. And for each command in the windows like “fastboot -s Baytrail******* (you need YORU number) I just did that in a dos prompt.

            I have no clue what I am doing all new. Yet what I thought was bricked WORKS again. So you are NOT bricked. You have to search the teclast froums I just reg ..I know its in chinese. But CHROME works great. I would just post kdkdksksk and then I could see all. And I fould someone that made a SWF vidoe. IT WORKS. GOT TO SEARCH. YOU CAN fix it.

          • gumble

            do you have a solution? same here: win8.1 without touch, the reflashed android bios. stuck in “intel lnside” screen. the using intel’s ManufacturingFlashTool with the chinese image (X98 3G安卓固件). now stuck here:

            So your Teclast works well on Windows 8.1? Only camera and 3g not orking? Teclast without 3G on Windows is bad idea. In next 5 days will Onda sell V975w with preinstalled Windows 8.1 and all the same screen etc, only without 3G and the price little lowest.

          • jachas

            Yes, exactly like you said. But this is my first tablet with windows 8.1 on it and I was not aware about some difficulties connected directly with this OS on such a small screen with such a big resolution, e.g. some applications (chrome) have to be scaled properly to be usable by finger but because of that they appear not really sharply (actually just flurry). Another problem, this time connected to device itself is that on the edges screen is much less responsive to touch. I mean it doesn’t react at all or the place of touch is not precisely reflected. Don’t know if this is a problem of whole sort of Teclast X98 or just mine. Besides it tends to be much less precise after some time on the whole screen and you have to restart it to be usable again. And there are some devices without drivers in device manager, some applications not working correctly (e.g. nod32 what makes me a little suspicious after recent news about trojan installed in firmware of some chinese phone :/) Not to mention about 3G and camera… So generally I’m rather disappointed by the whole experience and waiting for any further updates from Teclast. Furthermore I have to try Windows 8.1 on other device – from the top of the market – because maybe my problem is with the OS rather than this particular device.

          • Tom

            My device is also not very responsive near the edges of the screen. Under Android os that is.
            This might be just the way those tablets are.

          • jachas

            Yeeah, but this could really be a pain in the ass on Windows where whole bunch of useful tools are just on the edges (taskbar menubar) having a hard time to chose right tab on webbrowser. But now when I’m writing this I realized that was not a problem on android, tabs on browser are in the same place there, just under the top edge, don’t they?

          • Tom

            On Android there is this status bar with clock and all the icons. It is like 0,5 cm wide , after that there is web browsers tab bar.

          • jachas

            Yes, it’s this what probably makes the difference. Anyway, did you succeed in update your tablet? I’d like to hear anyone else’s opinion about Win8.1 on this device.

          • Bambosz babci

            Also you don’t have problem with sleep and hibernate?

    Nice tutorial!
    But are these the *official* files from Teclast?
    Or is the company still going to release an update which also supports the cameras and 3G, in the future?
    Thanks for the info!

    More easy using a Virtualbox machine and Hirensboot with Ghost and create a backup of Windows 8.1 installed in the virtual machine, and install this with hirensboot with ghost in the Intel tablet!!

    Hi, do you have some WiFi issues with this tablet? I got mine before 5 days ago and my WiFi signal is very poor compared to my other android devices. Only when I’m very close to the router and have full signal internet working very well, but when i have signal 50-60% or less download is bad and upload is awful (on speedtest) and internet don’t work or work with many packets loss and very slow. Also when I’m holding it in my hands or in landscape position signal decreases. Do you have some advice how to improve this or resolve problem?
    Thank you in advance.

      I think this is related to the aluminum back plate, this was a common problem back then with a famous phone maker where they had to attach a non conductive back plate over it, check out antenna gate, no flame please. GSM and WiFi is slightly different frequency but having same type of antenna, so orientation and even blocked by hand will affect the signal quality. Try using a stand mount.

    Hi! I am a member of the Russian-speaking forum 4pda.ru, my nick is kostyamat.
    I created a CMD script that automatically performs all the steps necessary to install Windows on a tablet. The script is able to install ROOT rights, create bootable USB flash drive, flash BIOS, download all necessary files from my GooglDrive, install the drivers, flash update.zip via sideload ADB in Recovery, Flash Firmware to tablet using FastBOOT mode without very naughty “Manufacturing Flash Tool” and much more.

    Download: https://drive.google.com/file/d/0B2EtzBgf13KZbGhZalpDM3VUanM/edit?usp=sharing

    Using: Unpack the archive to any folder or disk, run 1_Toolbox.bat, wait until the drivers are installed, perform the requirements of the script. For flash update.zip – put it in the working directory of the script. To flash firmware – unpack all files of firmware archive to a working folder of the script.

    ATENTION! IT DO NOT WORK ON WINDOWS XP OR ABOVE.

    Wellcome to try it!!! :)

    The latest version is always here: https://drive.google.com/folderview?id=0B2EtzBgf13KZOXFWRHhQMlZnLVk&usp=sharing

        Ugh.. I’m just going back to android if that’s the case. I wonder what caused this? I’ve looked at several instructions and they all show success right away. I wonder if the fact I’m using an /iso from MS intended for a desktop has anything to do with it?

    I have heard the 64 bit w/Bing has a smaller install footprint than a full on 8.1 pro edition, is this correct? I have Win 8.1 w/32 bit installed, I wanted to put a 64 bit version on it but I cant direct install from a bootable with uefi (no legacy setting either) and my main pc no longer recognizes the X98 air 2 when plugged in. Any help/suggestions/advice would be appreciated.
