[Q] Download mode not compatible with Virtual Machine?

Hello all.
First of all, before people shooting at me and saying "please search", I come from many Google and xda search with "MacOs, download mode, failure vm, virtual machine, odin , kies" in every combination you can imagine and no result.
So, the problem is the following one:
I remarked, with some friends from a french forum that we all succeed to use KIES in a virtual machine and connect the phone:

That work like a charm.
Then w wanted to flash, then reboot the phone in Download mode ( yellow android at work ) and then there is a big crash telling us that the device is not recognized:
"unable to connect USB device to virtual machine"

I would really be pleased to have more info on this issue and if we are only a little group to have this issue.
For info, I am using MacOS Snow Leopard and the trial of parallels desktops 6.

It doesn't work with VMware Fusion either. Must be something to do with the USB interface on Samsung.. I've heard some people have it going on Virtualbox running on Linux - but not Mac.

Works fine on VirtualBox on Ubuntu.

Why don't you give Heimdall a go? Haven't tried it personally, but OS X is in the list of supported OSes

Maybe I found the explanation , thanks to ed link:
Although Heimdall runs on OS X all Galaxy S phones tested thus far contain a bug in the secondary boot loader that prevents the phone registering itself with OS X. This may change if Samsung release an updated secondary boot loader.

Maybe there is the same problem.
Does the secondary boot loader has a link with download mode? If yes, that might be the problem!

Saw that today too.. .pretty sure its the issue since it affects all parallels, fusion and virtualbox on Mac OSX.

Yes, download mode functionality is provided by the secondary boot loader. If you really desperately want to get it working with OS X then you would need to download the source for, modify and install a custom IOUSBFamily.kext that contains a work-around specifically for the Galaxy S.

The only options for we Mac users right now are to find a Windows machine, install boot camp on your Mac (then point your vmware machine to it to save duplicate Windows wasted space), or possibly find a way to boot from an external drive with Windows (like a thumbdrive or livecd if possible).

Exactly what i have done. And I HATE it :|

I had this same problem, and I just saw this thread after spending hours last night trying to figure out why XP in Parallels stopped recognizing the phone as soon as it went into download mode. So irritating!

it works for me on VMware 7 + WinXP SP3
because my Win7 64bit PC is crazy it won't recognize the phone randomly, twice it bricked my phone doing the Flash on the Host PC
so after setting up my ROM FLASH VMware machine, now i no longer have problem
stupid windows, no time to mess with the system registry to figure out what is the madness with the USB detection
i'm pretty sure you should have no problem as well if you use VMware 6.5

I posted this in the Heimdall thread but thought I should let followers of this thread know also.
I sent Samsung the OS X USB failure log and since then Samsung have informed me that the Froyo update (specifically the Nordic version released October 15) includes a fixed bootloader which should allow the phone to be recognised in OS X. I'm yet to verify this but hopefully this is the case!

[Q] Teclast X98 Air 3G: Semi-brick

Hello XDA!
I Pray for Help
I have a tablet: Teclast X98 Air 3G 32GB C9J8.
- It all started with the fact that when you install Windows 10 I formatted all partitions.
- Windows 10 install. Everything worked well, except for the battery. The battery not charging while working in Windows.
- It was decided to return the Android OS. But it was not there. I was not able to install android through Manufacturing Flash Tool, because the partitions have been deleted.
- For a long time I was looking for ways to solve this problem, but the solution I not found.
- Well, to hell with it with android - I said. But the problem is that while I was looking for a solution to this problem - I created another problem:
Now tablet not booting to Windows 10. After turning immediately goes into the BIOS. And when I try to run the install from a flash - nothing happens.
- I tried to boot from a live usb, but no result.
- I think something happened to the EMMC.
- But there are two workable options: EFI SHEll and WinPE5_TechAdmin_UEFI.
- EFI Shell works, but does not allow to load the installation Windows with usb flash by running and bootia32.efi or bootx64.efi.
- WinPE5_TechAdmin_UEFI: Run the menu with different options:
- Installation
-diskpart
- Acronis
- etc.
Windows installation runs but produces different error types: ACPI_Bios_Error or 0xc0000XXX - winload.efi
Acronis starts, but after entering my tpad hangs.
- Who can recommend?

Hello mate . Any changes? Did you fix it ? I got techlast x98 3g 64 gb fully working maybe i can help you with somethig to take my os to upload on a server . Maybe you can fix it . I have no ideea . Just trying to help

Hi everyone.
Any idea or problem solution?

Nothing happened in the meantime ?
I am in more or less the same situation. So I liked to hear what now is yours.

I am in the same situation as you, i cannot boot from any usb device, i also tried booting from the efi shell but of course i had to same problem as you. At least i still have my android 5.0 rooted that works fine but i would like my windows to also work
I have tried a lot of things but am also nearing a wall and was just about to make a similar thread as you.
Edit: My situation is not exactly the same as you as my windows 8.1 is not working instead of win10... When i try booting into windows 8.1 i instead get a blue screen and get to the recovery options for windows 8.1, but none of the options work. Of course i can use the CMD option but chkdsk and similar commands don't help

Have you tried to flash a custom android rom like mireks?

Teclast X98 Air III 32GB Android version - Install Windows 10

Hey guys,
my x98 Air III will arrive in the next couple of days and I plan to run Windows 10 on it. i got the 32GB Android only version and hope since there is a 64GB dual boot version that the bios isn't locked and I can boot from USB. Has anyone tried this already?

i want to give it a try but i'm a bit scared i mess up my shiny new tablet...
i found some more info and it looks like it should be possible to turn my tablet into a dual booting device. The 32GB version that I have is M5C5
http://bbs.teclast.com/thread-518225-1-1.html
i just connected a powerd hub and put teclast win10 on an external usb stick. i interrupted the boot by hitting esc on boot, tried to launch from usb, but it didnt work..

Ordered mine yesterday. My plan is also to put Win10 on it, so I'm collecting info/files on how to do it. Maybe Chris from TechTablets will make a video of the process before mine arrives?

he just released a review: http://techtablets.com/2015/11/teclast-x98-air-iii-review/

I've managed to install the dual boot bios on my Air III, but couldnt figure out why flashing was failing. Every time it would go to 10% and fail (when using that Intel's flash tool).

So how did you make it work? Could you post some instructions?

I was succeeded flashing dual boot bios,
and re flashing android 10G patition .
however, I cant boot windows to install it.
dual booting mod didn see windows logo.
I trid to make a booting USB, winpe USB.
didn work out.

Im at that stage now as well. I couldnt flash the rom automatically so I had to manually input the fastboot commands. Got few things to try in regards of delpoying Windows on it, but that will have to wait until I get home though.
I will put together a guide once I manage to get Windows working, hopefully sooner rather than later

How did you manage to install Windows? Can you provide links to files needed to install it?

I'm pretty happy with Android right now, but I wonder if the UI response is more snappy under W10. I already have a USB prepared with the Teclast W10 version. Just waiting for instructions on how to flash bios etc..

I have done a clean Windows 10 Home 32bit (TH2 1511) install and use the driver package from HERE.
All works fine yet but i know one issue with screen brightness:
When i tap the brightness icon (with 25-100%) there came a point with 0% brightness and i tick it and the screen was off and no chance to find the right button without screen
I restart the tab with 15sec. power button but after the short welcome screen, the screen goes back to dark.
So i must use a keyboard and start the tab in rescue modus and set the power managment to "standard". After this the screen was on after next restart.
My question: is it possible to delete the 0% entry in screen brightness?

How did you manage update BIOS? Did you flash it from Windows PC with USB Debugging enabled or from EFI Shell? My Windows desk cannot find Air III, it says 'no devices found'.

I have managed to put windows on it, by downloading all the files directly from Teclast forums. However, windows is in Chinese and I cant seem to change the language to anything else. Everytime I download a new language, it fails without oving me a reason any suggestions what to do?

if you let me know how you flashed the bios and which files you used for the install, i will put it on my tablet as well and we can figure it out together

Thanks, did that and all is fine now. Only trouble was none of the drivers were included in the official ISO files, so I had to manually install a lot of things. The file that can be downloaded directly from teclast is optimized and preconfigured with all the drivers that are needed.

First of all get this: http://pan.baidu.com/s/1kTyAH2f
Secondly, follow this tutorial to install all necessary drivers and tools: http://forum.xda-developers.com/showpost.php?p=62823535&postcount=5
Thirdly, manually edit "Update_Android.bat" file (comes with a package that you have downloaded as the first step) to make sure that all file paths are correct - most importantly the 4th line of this wile, where it points to Intel Manufacturing Flash Tool. Also make sure that there are no Chinese characters in any of the file paths.
Lastly, run "Update_Android.bat" and follow the instructions there I've found that unless you get everything right (all file paths and tool) there isnt much risk of something going wrong, as nothing will actually happen.

thanks for the info! just installing windows 10 on my m5c5 32gb air iii right now, seems to work bios flash was easy and painless. after flashing it took a while for the tablet to power back on. it also didnt see my win10 install usb stick at first. after a few trial and error attempts it eventually booted into windows install.
I'm installing stock windows. which drivers did you use to get the tablet fully working? right now I'm getting the July 2015 Air 3g Windows 10 drivers from techtablets

I have used the same package, majority of drivers can be downloaded using Windows, but there are some missing and thats where the package comes in useful.

Best Rom and Bios for X98 Air III 32GB M5C5 FEB 2016

UPDATE MARCH 2018:
I finally converted my Air III tablet from an Android only into a dual boot Win 10 and Android system. I'm using my laptop a lot in the office these days and didn't feel like schlepping it home every day. My Air III is now my home computer.
I'm surprised that it can run one of my favorite games that just came out: "Into the Breach" with no problem. I connected a Apple BT mouse and it's a cool little portable system for Indie games. Other ones I tested that run well are Shovel Knight, Super Meat Boy, Celeste and FTL. As a gamepad I use an Amazon FireTV controller that I link up through BT.
For those of you who still tinker with this tablet, here are some instructions to get dual boot working:
1. Install Mirek190's v7 rom for Air 3g. Copy the 6GB partition table and also the "boot-air3-m5c5-moded - boot.img" (extra download from mirek) to the ROM folder. For your convenience, here is a ready to flash version for the Air III, already modified with the right boot.img and 6GB partition table: https://mega.nz/#!5xMVgRyC!gHfvg3L3kXzL-NOFfTHvk4_nalKRM-io8DtnGhRCUXU
2. DOWNGRADE YOUR BIOS! - This took me a while to figure out. 2.05 is still the best bios to use for Android only but if you want Win10, downgrade to 1.00. 2.05 Bios does not work for dual booting on Air III.
This is not without risk, but I confirm that the following link to the 1.00 bios worked for me: https://mega.nz/#!VgMWVZjZ!SgSzryJkn89RWMidg_Um8Ab1wgDnZ8JWGwgK-yR2dj8
Unzip the contents of the folder to c:\update_android - If you have Mirek190 v7 installed it will have Supersu and USB debugging already enabled for you. Execute c:\update_android\android\Update_Android.bat with the tablet booted to Android. Note that there is two Update_Android.bat files. Makes sure to use the one in c:\update_android\android\
3. After the successful flash, connect a powered usb hub to the tablet via OTG cable. Connect a keyboard and USB stick to the hub. Follow instructions from Techtablets: https://www.youtube.com/watch?v=rLjayeQJg4Q
In order for a successful Windows 10 install you need Rufus and a 32bit copy of Windows 10. I used en_windows_10_enterprise_x86_dvd_6851156.iso. Create the USB key with Rufus and make sure to choose GPT partitioning.
4. After everything is set up, install drivers for Win10 Air 3G from Techtablets
5. Android should have around 5GB of space and Windows will end up with 15GB of free space. It's good practice to install software to an external SD. Especially WIn10 can run out of space quickly with all the updates it loves doing.
Hope this helps someone

ORIGINAL POST FEB 2016
Hey guys,
I just installed the following bios and rom to my Air III M5C5. I switched back from Windows because Windows was somehow buggy and didn't have much to offer for tablets:
I followed Kuba's advice ( http://techtablets.com/forum/topic/best-rom-for-x98-iii-m5c5/#post-25075 ) about best rom and bios for M5C5:
DOWNLOAD ROM https://mega.nz/#!8s92TbCR!w-vVyqbnqVf3p3YJP_obj2xRm_7f7sx9YMqVhLm4hXA
DOWNLOAD BIOS http://forum.xda-developers.com/showpost.php?p=65166671&postcount=87 (thanks to skubidoo)
You will also need Mirek's ROM: http://techtablets.com/wpfb-file/x98_air_2_android_5-0_mirek190_v5-0-ultra-light-7z/
I can confirm my X98 works better than ever! Both cameras are working and the device feels snappier than the original Teclast Android rom that came with my device. The rom is the official Teclast X98 Air III rom for recently shipped devices. Thanks to guvno for making this available to everybody! I first thought I will install the debloated Google Now rom for the air iii but since this is based on the original Teclast rom that I used to run, it wouldn't have been an improvement in terms of speed.
Here's how to install the ROM
PREFERRED METHOD TO GET THE RIGHT BATTERY DISPLAY:
- Prepare guznos rom for MFT:
Go to folder "X98_Air_2_android_5.0_mirek190_v7.0-ultra-light" - "ROM-backup"
Copy and replace droidboot.img, efilinux-userdebug.efi, flash-full_with_REPARTITION.xml and installer.cmd to the guzno folder.
- Install MFT software following tecknight's tutorial (http://forum.xda-developers.com/showpost.php?p=62823546&postcount=6)
- Now start MFT and select "flash-full_with_REPARTITION.xml" from the guzno folder.
ALTERNATIVE METHOD:
- Install the drivers IntelAndroidDrvSetup1.10.0.exe and IntelDnXUSBDriverSetup.exe in Win7 from "X98+Air+III(M5C5)+-+guvno"
- I put my device in DNX mode (holding down vol up, vol down and power when tablet is switched off)
- Used the batch file "flash_rom.bat" from "X98+Air+III(M5C5)+-+guvno" which then installed a freshly rooted rom of android.
Here's how to install the BIOS
I downloaded X98_Air_2_android_5.0_mirek190_v7.0-ultra-light, replaced /data/BIOS/2-05.bin with the one from the above mentioned link (https://mega.nz/#!dYxVTQrL!J9h-bk-hWzE80UK2MSzRd2CBiAoYY8TF6XXr-JwpgdU). Then I launched FLASH_tool_Teclast_x98_air_devices-v3.0, hit 4, then hit 2 and select 2.05. IMPORTANT Make sure you select only this version and make sure you replaced the right file. Be very careful with this step because if you accidentally flash the bios from the Air II to your Air III, it can brick your device!
For me, it worked correctly and updated my M5C5 to the most recent BIOS. You can tell because the tablet doesnt start up displaying chinese letters anymore but instead showing the latin letters TECLAST
If you want to keep your Windows installation I believe you have to change partition.tbl but not sure how this would work. I'm Android only now.

please can you post a screenshot of the device versions (Android Version, Kernel-, Build-Number, etc.)?
Thanks,

Android 5.0, build number is V1.00_20151204, kernel version 3.10.2 (December 7th 2015 10:50:43 CST).
This version is already with root

This rom works really great but the notification bar is flickering in some apps, someone has the same problem?

Yes, I'm returning to Sikke1's Rom because the flicker annoys me
I tried mixing Clean Rom+System.img from Sikke1's Rom and is working very good, but unfortunately the rear camera is upside down.

Try to disable gravitybox if you are using it. That helped for me on the flickering issue on mirek's v7.0 rom

So is this new stock rom worth switching? what about ui fluididy and battery calibration problems? has anyone tested it, who really does know the problems of the other available roms?

There isn't gravitybox into that ROM as mirek's, so thank you for your reply, if i found how to solve it, i will write here

Right, there is no gravitybox in stock ROM.
The battery status is fine for me, the only thing which is not 100% OK for me (beside this flickering) is the touch screen sensitivity.
Some times a have to touch twice for reaction - is this normal for this screen?

battery is reporting the correct values and i don't seem to have the flickering problem. i'm very happy with my Air III now, it's a big improvement in UI responsiveness to the original one. i didn't notice any problems with sensitivity...

Glad this ROM was usefull to more than just myself. Thanks to ionioni and hordarian for the adb commands on dumping and packaging the dump files to a flash package.
I myself was using custom ROMs until one of my units came with a clean AOSP ROM which this is. Finally Teclast has started to supply their customers with this instead of their bloated versions. All manufacturers should do this IMO. Release their own customized version to the general public but give the tekkies a clean AOSP version to play with ☺

For me the best rom is android 4.4 mirek version or other.
With android 5.0 battery drain so fast, just try android 4.4
My bios is dualboot V1.00. (m5c5)

i noticed the flickering notification bar today in google photos and tapatalk when scrolling. clearing notifications seemed to get rid of the problem. considering all the problems i had with tablet in the past ( battery drainage, random freezes, screen unresponsive, slow scrolling, lagging, constant driver installations and updates in win10) this wont bug me much.

Just to complete the picture:
The BIOS Version is:
Project Verion: tPAD 2.05
Core Version: 5.008

Right?

You can fix the flicker by checking "disable hw overlays" in developer options. It doest seem to have major disadvantages turning this on from what I gathered...you basically force the use of the GPU for screen compositing which might free up the CPU but might have some unwanted side effects like obstructed image rendering. I think you have to turn it back on after restart or use a script like this one http://forum.xda-developers.com/nexus-4/help/disable-hw-overlays-force-gpu-rendering-t2227089/page2

Can I flash this rom over sikke1's debloated rom without any issue? Because sikke1 rom has 100MB cache partition and 1GB data size. Does this matter?

If you use the flash ROM batch file with the standard partition table it will completely reset your tablet. So no, it shouldn't matter. I had windows installed and it just repartitioned the tablet.

Can Teclast X98 Run Chrome OS

Can X98 run Chrome OS???
It seems the old dog needs a new trick and I am wondering anyone has any knowledge on how to flash a chrome OS onto an X98 pad
(not need to care the dual boot system anymore, but I don't want to brick the machine either...)
Thanks,
Tony
Update:
I do have a bootable usb and usb port hub for keyboard and mouse...
-Do enter the x98 pad Bios and change the boot sequence and it does not work.
-Do go to the win10 advance reboot and it does not work...
and then read other flash methods:
-Try using PhoneFlashTool but it do not recognize the ChromeOS zip image.
(should I flash the pad like flash a Linux system for the pad)
What can I do next...
Update #2
Using override boot in bios with a USB stick and it will install the whole thing at ease, however, there is no touchpad and sound...
However, when I install virtualbox in the ChromeOS and then reboot, the USB function is all gone!
Now I am stuck again...
(*use rufus can install any bootable OS on scandisk USB stick, highly recommended.)

Hi @grygry777, I'm also interested in installing chrome OS on my teclast, could you please share some insights from your experience?
Did you use chromefy (croissant)? what images? what is working / not working?
What's required for the flashing process? if you don't care to elaborate about this part a link would be great too.
What OS did you end up with?
Thanks

Hi @TrampGuy, I just using "[email protected]" one,
Use Rufus to install an image in a usb stick.
The flashing process is simple and forward in the bios setting, and the rest is pretty automatic... make sure you have a mini USB hub for mouse and keyboard all the time...
everything goes fine (and fun) but right after I install VM which recommended by them, the USB function is all gone...
(now the machine is a 'functional brick', since I have minimum knowledge in BIOS side, I don't know what to do now... The point is I cannot reflash the bios using those three files(IntelAndroidDrvSetup1.5.0, iSocUSB-Driver-Setup-1.2.0, PhoneFlashTool_5.3.2.0_win32), it's just can't find my device and I don't know why, really stuck here now)

Hi,
I have also such a thing lying around here and was wondering whether it will work to load ChromeOS on it.
Have you fixed your issues in the meantime? Or have you dropped the HW finally for scrap? What was the reason for installing VirtualBox inside of ChromeOS?
Tnx in advance! KR,
Hans.

The most information about those cheap China-made tablets will be on techtablets.com. In the forum you will find a dedicated section for the X98 Plus II. Fingers crossed you find someone there who can help unbrick the pad.
Have you succeded to get the touchscreen work before the machine went down? I have currently no idea how to solve that one.
Ah ... there are articles around, that you should never install virtuabox on chromeos (sorry, I know you already realized). Even though other articles state different messsages. Up until quite current kernels the HW virtualization support is not available in the kernels. Probably the discrepancy is related to specific processors ... I don't know.

Can X98 run Chrome OS???
It seems the old dog needs a new trick and I am wondering anyone has any knowledge on how to flash a chrome OS onto an X98 pad
(not need to care the dual boot system anymore, but I don't want to brick the machine either...)
Thanks,
Tony
Update:
I do have a bootable usb and usb port hub for keyboard and mouse...
-Do enter the x98 pad Bios and change the boot sequence and it does not work.
-Do go to the win10 advance reboot and it does not work...

Try Brunch framework, CloudReady or Fyde OS

So if anyone is still thinking about installing ChromeOS on Teclast X98.
I managed to get it running using the guide on
(sorry there is no official website or blog on this guy's work). Look in the description of the video for written instructions.
I can use the OS if I have a bluetooth mouse and my bluetooth case keyboard connected. I'm trying to look for touch drivers to insert.

I have an air 3g teclast x98 I'm very interested to try to install chrome os as on the android side I'm stuck on android 5 and I can't do many things

Hi drrayc,
did you manage to get the touchscreen working?

Nope. Had to use the keyboard and Bluetooth mouse. I never figure out which driver to inject.
