When setting up to nvflash my G-Tablet to recover from an install problem, I couldn't flash because my computer couldn't find the driver to install that would let my Windows 7 64-bit PC talk to my G-Tablet. Turns out that the file set I was using for nvflash did not have the drivers in it.
Per Roebeet's sticky thread I went to:
http://db.tt/Wm25t7U
and downloaded the Windows files:
nvflash_gtablet_2010110500.zip
nvflash_windows_20100500.zip
The second file with "windows" in the middle has the nvflash program in it and also has an Android USB .inf file listed in it. After working with it, however, I found that it does not have the drivers to go with the .inf file. So I searched all over Nvidia's site and everywhere else looking for USB drivers.
Then I remembered that I had downloaded a copy of Advent Vega's USB files while researching one day. I extracted it and put it in my NVFlash folder and tried flashing again.
When I connected my tablet to the PC, the PC immediately tried to load a driver -- but since it didn't know where my files were it failed. I then went to Start/Control Panel/Device Manager and found APX listed in the devices with a yellow "!" (exclamation point) on the icon. I then selected the APX item and found the "Update Driver" button and clicked it. When it ask where to search, I took the local computer manual selection choice and told it to Browse.
I then pointed Browse (and the USB install) at the "USB" directory under "SystemUSB" in my NVFLash folder. (The SystemUSB folder actually has a "Flash USB driver" folder under it with the "USB" folder under it.) I suppose when you extract from the original you could just put the "USB" folder in the NVFlash directory.
When pointed at the "USB" directory, the driver installed and I was ready to nvflash.
I did this myself successfully. I have read posts from two other folks who also have used this successfully. So I believe it works fine.
But, of course, I urge you use caution and can't promise something could go wrong. (Disclaimer complete.)
The USB driver download is at:
http://www.myadventvega.co.uk/
Find the "Downloads" tab in the middle of the page and click on "USB System Driver" to get the files.
I hope this helps.

I also posted the files in one of the nvflash related threads here.. if you have the msi you can do this:
msiexec /a %1 /qb TARGETDIR=%~d1NVtemp
move "%~d1\NVtemp\PFiles\NVIDIA Corporation\%~n1\usbpcdriver" %~d1usbpcdriver
thats a batch file.. and it extracts the msi without installing.. into <drive>\NVtemp\
%1 = file name
%~n1 = file name without extension
%~d1 = drive of file name
windows will fill in the blanks if you drag and drop the msi file onto the batch file you create.
fyi latest is tegra_ventana_froyo_20110207.msi .. well technically it is tegra_ventana_gb_20110222.msi - but they both have 01/31/2011 driver inf and 06/24/2010 dll files - so... not that new
this is the apx drivers rar'd up. from tegra_ventana_froyo_20110207.msi

Listed below is a link from Blades which provides the USB drivers we need without
having to load the whole SDK to get to them:

I hope he doesn't mind my moving the link over here since I have been trying to get
this info together where people having trouble can find it. Thanks to him for the info.

I posted it here first.. but no prob.. those drivers worked right away.. make sure to point to the inf file and not the subdirs AMD64/i386.. as they only contain dll files
Blades,
hmmm. I would have swore your edit was not there when I wrote my post. Certainly you can see that there would be no reason to re-post otherwise!!! Your edit was way before my post
unless there's something weird with the time stamp. Or maybe my tired old head is just working weirder than usual today.
Either way, your work is appreciated and you should get the credit for it. Thanks,
Main thing for me is that I am trying to solve the problem that people didn't have the needed USB drivers. Now we have multiple sources.

All,
Otreblada posted the following message in a thread over in General. Since it provides a download source for the NVFlash stuff we are talking about, I have copied it over here.
His work, not mine. It contains the nvflash file, image files and USB subdirectory needed to nvflash your tablet back to stock. I have not used it. He says it works fine.
"Get this zip from mediafire.Instructions inside zip file. It does work I created this zip after struggling for almost 1 hr trying to flash back stock rom."

EDIT: Since this post I have found a post by CyHawk which has a direct link to the nVidia Android SDK:
http://developer.download.nvidia.com/tegra/files/android_tegra_froyo_20101105.msi
If you download and install this it looks like it includes the nvflash stuff in the "windows" files listed above --
and more importantly it has a folder in it called "usbpcdriver" which contains the same files as the Advent
Vega download above. I have not used the nVidia SDK stuff, though, so I can't vouch for it.

When you unzip those 2 nvflash zip files do they containany zip files within them? When icicles I see abunch of files and a zip file.
isu205,
I don't remember any .zip files. The "nvflash" file does start off with an .inf file, but that is the USB .inf file that does not have the drivers with it (which is one of our problems.
If you:
1. Download the Advent Vega USB files
2. Down load and extract the two .zip files roebeet suggested.
Then put those files in a NVFlash subdirectory -- your are ready to nvflash.
That's all you will need to restore to the older bekit stock version.
(I think if you download the otreblada file it has the above already in it.)
Rev
P. S. -- You can find, download and install the nvidia SDK, and it will give you
the same files plus more -- but it also adds some complexity.
You pays your money and takes your choice!!!
EDIT: I double-checked and the answer is NO. No zip files I could find.
I'm a linux guy but do have a Win 7 Starter netbook. A while back I installed everything (sdk and USB driver)? necessary to grab screenshots using adb and ddms or QtADB and everything works well.
Anyway, does this mean all I need on the netbook is:
nvflash_gtablet_2010110500.zip
nvflash_windows_20100500.zip
to get nvflash up and running?
joe2262,
Yes, I think you should be good to go as you have described. Once you install the
USB drivers, or once ADB is installed in the SDK with its drivers -- the drivers stay in
the system and are activated when you connect the tab and PC.
And actually, I've never done it this way, but if you have the SDK you should have
the nvflash_windows-20100500 installed. All you would need is the .img files from
nvflash_gtablet_2010110500.zip (and the ngflash_gtablet.bat file which runs the flash
which is in the other .zip file).

I might have missed something.
I am trying to install the USB driver, but it looks like I am not having much luck.
I first tried to connect the Gtab while it was running the stock software. It showed that it connected with no problems. When I try to run it in APX mode, it does not show that the Gtab is connected.
Is there a way to go back and start over?
EDIT: I just tried it and it said that it installed the drivers - now it is showing something like NVIDIA USB Boot, but it is not showing APX as a drive.
I recover my gtab and it is working fine as long as I keep turned on... when I turned off and turned on again, goes straight to APX mode and I have to nvflash to get on.
Does anyboby knows how to disable the aPX mode?
I am using windows xp.
none of the drivers seem to work for windows xp x64... suggestions?
thanks for this!
Does anyone know where I can get the following files?
"nvflash_windows_20100500.zip" and ""nvflash_gtablet_2010110500.zip
Need to a restore on my veiwsonic gtablet and need these files to do so.
Thanks in advance,

When the kdz tool used to work on my pc which it no longer doesn't because my pc and laptop won't recognize my phone while its in S/W Update Mode. I recall seeing adb.exe file running in my task manager. Is this file the reason why my pc and laptop won't see my my phone anymore in S/W Mode cause I no longer see it in task manager running when I try to do the kdz flash? I ran a search for adb.exe on my pc and laptop with hidden files and folders enabled and the search turned up nothing. If this file is indeed responsible for my troubles, how can I get it back? Do I need to install andriod sdk to get it back?
I really want to root my Chinese android, but I can't do anything until I get the UBS driver for the device installed on my machine. The model is a K-touch U2.
Problem is, that after I downloaded from the manufacturer, it was just a zip file full of garbage:
msmdm.inf file
tymdm.inf file
tyser.inf file
tyusbser.cat
tyusbser.sys
...
What are these things? How do I make that into a USB Driver for my phone? I've tried everything, please help!
Someone please guide

Just delete Samsung kies, and file transfer works again.
for delete kies: download kies package again and inside package you find Kies uninstaller.
Hello guys,
I was having driver problems on my i15-TFL for some time and I solved it. I wanted to share with everyone who's having the same problem.
Sometime ago, I ignorantly removed both Windows and Android from my tablet to install Windows from an ISO I trusted. This caused driver problems and my tablet was lying around uselessly. Yesterday I decided to deal with the problem and downloaded some firmwares, mostly from this thread in 4pda.ru. I tried installing using the instructions but no avail. I just wasn't able to boot into the recovery USB. I installed back a normal Windows 10 ISO and tried to extract the drivers.
This is the solution I came up with.
1. On another device, obtain a firmware for the device (eg. TFL is my devices serial id).
2. Extract compressed file.
3. Go to images folder.
4. Explore or extract install.wim file. It is the image backup file. I used 7zip but I believe there are other programs capable of handling wim files.
5. Navigate to Windows\System32\DriverStore and extract the FileRepository folder.
6. Install Windows 10 ISO of your choice to your tablet.
7. Open Device Manager.
8. Update driver of each device you want to install driver and target to FileRepository folder.
You can also take the FileRepository folder from your own tablet before removing the original Windows installation.
Hi, does anybody have driver for webcam? After reinstal of Windows 10, my tablet can´t find webcam (and one other device, which I have no idea what it is). Thank you
